Thermal throttling at low temps way below TjMAX

I have a brand new Lenovo Legion Pro 7i gen 10 (with Ultra 9 275 HX processor), which recently after two weeks of use I started noticing that thermal throttling is being recorded at Max temperatures as low as 80 C° or 84 C° in some cases while playing using the Balanced mode, along with the use of a powerful cooling pad (Flydigi BS3 PRO).

Is it normal to have thermal throttling recorded with HWiFo at such relatively low temperatures?

(Note: I didn't notice issue with the performance, just knew that from HWiFO sensors' records which in some cases showed me up to around 5% Package/Ring thermal throttling average)

Given that usually I'm capping the FPS on most of the AAA games I'm playing at 60 FPS or 30 FPS+2X Frame Generation, without capping the frame rate & without the cooling pad my CPU Max recorded temps easily exceed the 100 C°

CPU Lag Problem

When playing games, after about 10 minutes i start to get very little fps for a few seconds every minute. Ive looked at MSI Afterburner and it turns out that my CPU suddenly starts throttling down to 800 MHs from my normal 3900-4600 MHz. I have tried lowering my power limit in Bios to 90 Watt instead of 150 Watt. It didnt help.

My Specs:

GPU: RTX 3060

CPU: 11th Gen Intel(R) Core(TM) i5-11600K @3.90 Ghz

Motherboard: B560MX-E PRO

Notes:

My fans get really loud shortly before the lag and then stop for a second.

It mostly happens on games that are harder to run

My GPU perfomance also hits 0%, but its probably because the cpu isnt giving it anything do.

I got 16 Gigabyte of RAM, PC is using mostly at 14-15 Gigabyte while playing (I dont think RAM is the issue)

New legion thermal throttling

I bought this new Legion Pro 5 16IRX10 it's just been 3 days and it runs pretty hot the cpu is i9-14900hx and the gpu is 5070 lot of people recommend me to undervolt is as the cpu is way to power hungry and can run way to hot but even after finding some decent values to undervolt to it's still thermal throttling idk what to do laptop is elevated. It's brand new and the cinebench score is 30,079.

It's still throttling after undervolting

Any recommendations?

Work in Progress Dell Undervolt 12th, 13th, 14th gen and up - Public 1st draft

I posted this as an answer to someone. Thought I should make a post as it took more effort and applies to lots of systems. Search for Alienware undervolt for more details as plenty of people tinker with those and have tried an undervolt. They have very similiar bios and issues. TLDR Disable CFG Lock, Undervolt Protection, and undervolt set in bios.

Got undervolt working even with Undervolt Protection on

This was on a Dell G16 7630 13th HX. I've dumped bios, searched it and used grub, but that takes more time then the universal form browser , UMAF. So I recommend UMAF

If you mess up, you may need to recover the bios. Look it up if this quick howto doesn't work.

  1. Hold power key to turn off.
  2. Hold Ctrl + Esc and then hold Power key to turn on. Keep holding until Power light blinks twice after about 30 seconds and then release and wait
  3. IIRC there is a screen that offers the option to recover bios, that you then select.
  4. Eventually machine will recover bios, and display a screen explaining the time has not been set.

I have undervolting working, but I still need to set the max undervolt I want to try at the bios level. You need to do small 10mv steps and restart a few times to make sure the machine still works and posts (you should see the Dell logo then OS) I also recommend holding F12 to skip loading the OS sometimes. Beware, If you go too far with the max the machine will have progressively worse issues.

There are risks changing settings at the bios level.

  • The machine will crash on load
  • The machine will crash even without load
  • The machine will crash but you can get into UMAF
  • The machine will display errors as it attempts to post, but let you get into BIOS, but not UMAF
  • The machine will even fail to let you into the BIOS, so you need to recover bios if clearing cmos fails
  • The machine will need to go into service as it can't recover bios

Secure Boot

Secure boot must be disabled, but iirc bitlocker will prevent windows from booting with bitlocker disabled if active. Again more warnings here as bitlocker will prevent you from reading any files you have on the drive except if you have the key. All data on the drive could be lost so you need to backup the bitlocker key. It wasn't an issue for me this time but I've lost data in the past except my backups.

Now here are the steps (This video shows procedure)

  1. Download the Universal Form Browser
  2. Format an empty USB drive and copy the Universal form browser to the drive
  3. Shutdown the computer or restart

Hold F2 as you power on the computer to enter bios

  1. In bios go to the boot menu and disable secure boot
  2. Save changes and reset

Hold F12 as you power on the computer to get boot menu

  1. In boot menu select the USB drive that you left in the computer and formatted
  2. If you forgot to leave or put in the drive hold power button 4 seconds to turn off

Once in UMAF

  1. Go in Intel Advanced Menu
  2. Go in Power and Performance
  3. Go in CPU - Power Management Control
  4. Disable HwP Lock (maybe not needed so best try without first)
  5. Hit up and select CPU Lock Configuration
  6. Disable CFG Lock
  7. Disable Overclocking Lock
  8. Hit Enter then hit Escape
  9. Hit Escape
  10. Go in Overclocking Performance Menu
  11. Enable Overclocking Feature if you want
  12. Disable Undervolt Protection
  13. Note Processor, Ring, Ecore L2 Configuration, GT, Uncore
  14. You will want to at first undervolt the processor by -10 mv
  15. The settings are called the offset and then the + or -
  16. You want to use a -
  17. Change Offset to 10
  18. You will come back to this menu to increase offset by 10 after every restart
  19. You will be able to open throttlestop or hwinfo64 and see the offset. Dont be confused by hwmonitor, as that app has a bug and gives an incorrect number.
  20. Hit Escape
  21. Hit Escape
  22. Press y to save
  23. Select Reset

Once back in Windows

  1. Throttle stop will still say Undervolt Protection , but you can now undervolt up to the limit set in the bios. Sometimes on battery the undervolt will not be stable so retest with a lower undervolt set in throttlestop or lower it in bios if you use Linux
  2. It is best to follow the undervolt guide by XMG and linked with throttlestop 9..7
  3. Limit your undervolt to only 10mv and work your way up.

Help regarding undervolting

I recently got a brand new Legion and I absolutely love the machine, but I’ve been reading a lot on this sub about how power-hungry these processors are. Everyone seems to recommend undervolting to keep the temperatures under control and maintain sustained performance.

Here is my current config:

Model: Lenovo Legion 5 pro

CPU: i9-14900HX

GPU: 5070

RAM: 32gb

I am a complete newbie when it comes to PC tuning, messing with BIOS settings, or tweaking voltages. I know I need to do it to improve my thermals, but I want to make sure I do it safely without causing constant blue screens or messing up my new laptop.

I don't have any specific voltage values in mind yet, and I am starting completely from scratch. I'm hoping to get some advice on a few things:

The BIOS: What exact settings do I need to unlock or change in the Lenovo BIOS before I can even start?

The Software: What is the best and safest software for a beginner to use for this (ThrottleStop, etc.)?

The Process: What is the safest step-by-step approach to finding a stable undervolt for everyday gaming and heavy workloads?

Also if anyone has the same laptop and done this can you share your values?

If anyone has any solid baseline guides, tips, or newbie-friendly advice, I would massively appreciate it. Thank you

Is 93–94°C CPU temperature normal just from using Chrome? MSI GF63 Thin 11UC

Hey everyone,

I have an MSI GF63 Thin 11UC that I've been using for about 4 years. Recently, I've noticed that the CPU temperature constantly stays around 80–95°C, even when I'm just doing normal things like browsing Chrome.

As you can see in the screenshot, the CPU is sitting around 94°C, while the GPU is only around 75°C. I'm not gaming on this laptop anymore, so these temperatures seem quite high for regular use.

I've already:

Cleaned the laptop internally.

Replaced the thermal paste about a year ago.

Kept the fans on Auto in MSI Center.

If I switch the fan mode to Turbo, the temperature does drop somewhat, but the fans obviously get very loud.

Is 93–94°C normal for this laptop while using Chrome, or is something wrong?

What could be causing the CPU to run this hot? Is there anything else I can do to fix or reduce the temperatures? Would undervolting, changing power settings, replacing the thermal paste again, or anything else help?

Any advice from other GF63 Thin owners would be appreciated!

I have a metal stand too but didn't help much

Vibecoded: A software for HP Victus Overheating

As title said, I vibecoded an software for my laptop.
The issue:
My laptop, which has AMD Ryzen 5600H CPU and AMD Radeon RX 6500M GPU had an incredibly frustrating heating issue where my hotspot temperature reached 100 degrees without right away, and throttling directly which reduced my fps by 50% almost and again reached 100 degrees, this continued in an cycle.
For this, I tried various methods, locking fps to 48, lowering resolution and graphics, and some of these worked too, but still in games such as where winds meet, elden ring nightreign, the temperatures kept hitting all time high.
Which lead to me trying to look into undervolting, and to my surprise HP Victus in particular has no way (afaik) to undervolt, because it is restricted at a BIOS level.
This lead me to discovering Universal tuning utility and Ryzen controller, which worked great but sacrified much of my performance to keep temperatures in check.
Annoyed by the lack of direct temperature control, i vibecoded an software which directly targets the dGPU hotspot temperature and it honestly been working really well for me.
This leads to me making this post, for this felt too good to be true to work, that i was wondering if i was damaging any of my hardware in the long run with this app.
If anyone can check, if it is problematic or not for the system, and give some opinions about it, it would be much appreciated!

TLDR: I vibecoded an app to keep thermals in check for laptop having AMD Radeon RX 6500M and AMD Ryzen 5600H, and would like opinions about its safety while using, and would like to know if it is damaging my device in any way.

I do not know how compatible it is with other devices.

Lenovo Legion i9 undervolt

Hey guy, I'm totally illiterate in undervolting cpus, and this is my first proper nice laptop which I want to keep for long. From what I know, intels 14th gen chips have some voltage issues frying them, so I want to prevent that. What are good settings for a Lenovo Legion with a 14900hx on throttlestop? How do I even set it up? All I know is I'm getting around 27000 on Cinebench r23 and this chip apparently gets 30 to 35k. Many thanks to you guys who can help! Edit: MP ratio is 13.27 as well if that means anything, my cpu has 24 cores.

Stop panicking about 95°C: A 5-line guide

  • Seeing 95°C is perfectly normal; modern Intel and AMD mobile chips are strictly designed to boost until they hit their thermal limit to maximize performance.
  • Instead of worrying, just prop up the back of your laptop 1–2 inches—this improves airflow and drops temps instantly.
  • Clean the dust out of your exhaust vents with compressed air every few months so the fans don't suffocate.
  • If you still want it cooler, use ThrottleStop or G-Helper to slightly lower your power limits (PL1/PL2) rather than completely disabling Turbo Boost.
  • Avoid liquid metal unless you are a pro (it can easily short your board); stick to high-viscosity pads like PTM7950 if you ever need to repaste.

Is 101–103°C with thermal throttling during 90% of a short Rocket League session normal for an MSI gaming laptop?

Hi,

I have an MSI Crosshair 16 HX AI D2XW gaming laptop with an Intel Core Ultra 7 255HX. I am experiencing heavy stuttering and short freezes while playing Rocket League, so I monitored the laptop with HWiNFO64.

After approximately 7 minutes of gameplay, I recorded:

  • CPU maximum temperature: 103°C
  • CPU average temperature: approximately 94°C
  • Core Thermal Throttling: detected during approximately 92–93% of the monitoring period
  • Package/Ring Thermal Throttling: approximately 87%
  • Average CPU package power: approximately 44–46 W
  • GPU temperature: approximately 62°C

Only some of the P-cores appear to reach extremely high temperatures and throttle heavily, while the other cores remain considerably cooler. Some individual P-cores showed thermal throttling during 60–86% of the test.

The test was performed:

  • With the original MSI charger connected
  • On a hard, flat surface with the air intakes unobstructed
  • Without any overclocking or undervolting
  • With different MSI Center power profiles
  • During Rocket League, which should not be an especially demanding game for this laptop

The CPU has a maximum junction temperature of 105°C, but it is getting extremely close to that limit and appears to be throttling almost continuously. The GPU temperatures seem completely normal.

I understand that gaming laptops normally run hot, but is this amount of sustained thermal throttling normal? Could the large temperature difference between the P-cores indicate uneven thermal paste application, poor heatsink contact or another cooling-system problem?

Could this explain the stuttering, and would you recommend sending the laptop back under warranty?

I purchased it in September 2025, so it is still covered. I have not opened the laptop or modified its cooling system.

P.S. HWiNFO and MSI Center are displayed in French because my Windows installation is in French. The relevant column headings are:

  • Réel = Current
  • Minimum = Minimum
  • Maximum = Maximum
  • Moyenne = Average
  • Limitation thermique du cœur = Core Thermal Throttling
  • Étranglement thermique du paquet/anneau = Package/Ring Thermal Throttling
  • Consommation d’énergie totale du CPU = CPU Package Power
  • Performances extrêmes = Extreme Performance
  • Équilibré = Balanced

Thanks for your help.

Dell Inspiron 15 7567 CPU drops from 3.6 GHz to 0.4–0.9 GHz under load — BD PROCHOT issue?

Hi everyone,

I have a Dell Inspiron 15 7567 Gaming with an Intel Core i7-7700HQ, and I'm having a strange CPU throttling problem.

When I turn on the laptop, the CPU runs normally at around 3.4–3.6 GHz. However, as soon as I launch even a very lightweight game, the CPU frequency suddenly drops to around 0.90 GHz, and sometimes even 0.4 GHz. This causes extremely low FPS and makes the laptop almost unusable for gaming.

The strange part is that temperatures are completely normal:

CPU/GPU temperatures stay around 60–70°C or lower

HWiNFO does not show thermal throttling

The CPU is not overheating

The laptop has the original 130W Dell power adapter

The battery is also original

The BIOS correctly recognizes the 130W AC adapter

I found a temporary workaround using ThrottleStop.

If I disable BD PROCHOT in ThrottleStop and press Turn On while the CPU is already throttled, the CPU immediately returns to normal frequencies (~3.4 GHz) and stays there, even while gaming.

However, this only works until I restart the laptop. After every reboot, the problem comes back and I have to manually enable the BD PROCHOT workaround again.

I don't want to rely on ThrottleStop or any other workaround permanently. I want to find and fix the actual hardware/firmware problem causing BD PROCHOT to trigger.

What could cause BD PROCHOT to be triggered on this laptop when CPU temperatures are completely normal?

Could it be related to:

the VRM?

the GPU power circuitry?

the DC-in/power circuit?

the motherboard?

the 130W adapter?

a faulty sensor?

BIOS/EC firmware?

And is there a way to diagnose which component is actually asserting BD PROCHOT?

Any advice on how to permanently fix this would be appreciated.

Acceptance?

So, i bought my first gaming laptop, dell g15 5530 , i5 13450 HX , 1 month ago , out of the box it was lagging (on battery only) , i learnt more and downloaded throttle stop, turns out i was facing BD PROCHOT and POWER RED at the same time hence CPU stuck at 500 mhz. BD PROCHOT option was ticked and greyed sadly.

Tried for replacement , for like 2 weeks but couldn't convince dell , cause nothing popped up in their own diagnostics test, at last thought it is what it is.

Tried everything to get out of 500 MHz trap , NOTHING worked , i was broken and thought i just wasted money, then i dig more and learnt about UEIF variables , read BIOS image , and turned the BD PROCHOT offset's variables to 0x00 from grub shell. BD PROCHOT was now greyed out and unticked , felt too dam happy that day and 500 MHz was done and dusted.

Then comes the next problem POWER - PL1/PL2 RED (this one is occasional and comes on battery, idk what's the trigger point but sometimes its smooth at 30 W package power and sometimes laggy at 10 W with normal clock speeds)

For this i again tried the same method and tried to change overclocking lock from grub shell , but this time i wasn't that lucky. Then went to IMON slope (it tricks your PC that it's using less power and hence pushes some more watts , exactly the pl1/pl2 absurdly low limit i was facing) set the IMON slope to 70% from grub shell AND it changed nothing :) , previously cpu was pushing 100 watts in cinebench now 70 , lol nothing but just inaccurate telemetry. Didn't pushed past that 100 watts wall basically.

Then read unclewebb's comment and he said that this thing is because dell's manufacturer set these pl1/pl2 limits too low , and not a easy way to fix it. (EC is overriding grub shell's variables and throttle stop)

I was also looking for undervolting but again , i could only slide the sliders in FIVR to -105 mv and i was happy that my pc is now undervolted LOL , until i saw that UNDERVOLT PROTECTION on top middle of FIVR screen🙏

Researched about it and again went to grub to switch (undervolt protection) 0x1AE to 0x00 , again not solved (already turned off VBS from BIOS)

Then finally i am here sitting and just accepting that it's over , i cant undervolt my laptop and also that pl1/pl2 red on battery will stay with me for the rest of my life with this pc.

If anyone have solution for my situation , i will be more than happy , please drop your thoughts as well😊

P15 Gen1 Overheating

Hi,

I have a P15 Gen 1, and under full load without a TDP lock, my CPU constantly hits the 100°C thermal limit. With a 60W TDP limit, it hovers around 95°C, but that doesn't seem healthy to me, and I'm losing performance because of it. The CPU downclocks to around 3.76 GHz and stays there with the 60W limit. I’d really like to hit at least 4 GHz, but that’s impossible with these temperatures. My fans don't really spin up high either; the CPU fan doesn't go above 3500 RPM, even using the ThinkPad Fan Control tool. I’ve applied MX-4 thermal paste and the mounting pressure is correct—I’ve checked it multiple times. The GPU runs at around 85°C under full load, so everything is fine on that front. It wasn't always like this with the CPU; the issue started at some point—I suspect after a Lenovo Vantage update, though I can't say for sure since I usually just let updates run without paying close attention to exactly what’s being updated. I’m running Windows 10 IoT LTSC and have no unnecessary background processes running. Right now, with 3 tabs and Signal Desktop open, the CPU is at 49°C, drawing about 5 watts at 3 GHz.

Is there an undervolting solution available yet?

If I can't do anything about it, I’m considering getting a P52, since I’ve read that you can mod the BIOS using a hardware flasher. Alternatively, I might get a Dell Precision 7530, as you can easily get MXM cards for them and they’re supposedly very moddable.

However, I’m a huge ThinkPad fan and it really bums me out that my P15 is giving me so much trouble, because I think it’s a great laptop.

Specs:

i7-10850U

32GB DDR4-3200

RTX 3000
