Lenovo LOQ 15ARP9 – CPU fan won't reach max 4800 RPM while GPU fan does. Is this normal?

Hi everyone,

I have a Lenovo LOQ 15ARP9 (Ryzen 7 7435HS + RTX 4050 Laptop GPU), and I noticed something odd about the fan behavior in Max Fan/Performance Mode.

The GPU fan reaches its maximum speed of 4800 RPM, but the CPU fan never goes beyond 4500 RPM, even though Max Fan is enabled.

Current readings:

  • CPU: 60°C, 8% utilization, 4500 RPM
  • GPU: 46°C, 11% utilization, 4800 RPM (max)

I've verified that 4800 RPM is the maximum fan speed, but only the GPU fan reaches it. The CPU fan seems to be capped at around 4500 RPM.

Has anyone with a LOQ 15ARP9 experienced the same behavior?

  • Is the CPU fan intentionally limited to around 4500 RPM by Lenovo's BIOS/EC?
  • Or should both fans be able to reach 4800 RPM in Max Fan mode?
  • Could this indicate an Embedded Controller (EC) firmware issue or a hardware problem?

I've attached a screenshot for reference. Any insights from other LOQ owners would be appreciated.

Lenovo LOQ VRAM Stuck at Max Frequency (8.00 GHz) in Lenovo Vantage – Possible Fix

Hi everyone,

I noticed that my Lenovo LOQ (Ryzen 7 7435HS + RTX 4050) is showing the VRAM constantly running at its maximum frequency (8.00/8.00 GHz) in Lenovo Vantage, even when I'm just on the desktop with no games running.

Symptoms:

  • GPU core clock changes normally.
  • VRAM is always reported at 8.00 GHz (100%).
  • Thermal Mode is set to Balance.
  • No overclock enabled.
  • Happens even at idle.

What I tried:

  1. Updated NVIDIA drivers.
  2. Updated BIOS and Lenovo Vantage.
  3. Restarted the laptop.
  4. Checked Windows power settings.
  5. Disabled hardware acceleration in some apps.
  6. Verified that no games or GPU-intensive applications were running.

Possible Fix (Worked for Me):

  • Open NVIDIA Control Panel.
  • Go to Manage 3D Settings.
  • Set Power Management Mode to Normal (or Optimal Power).
  • Make sure no high refresh-rate overlays, wallpaper engines, monitoring software, or browsers with hardware acceleration are forcing the GPU into a higher performance state.
  • Restart the laptop.

Additional Notes:
After checking with GPU-Z/MSI Afterburner, I found that Lenovo Vantage may sometimes incorrectly report VRAM frequency. The actual memory clock may be lower than what Vantage shows.

If your VRAM is also stuck at max frequency:

  • What NVIDIA driver version are you using?
  • Does GPU-Z show the same memory clock?
  • Is your laptop connected to an external monitor?

Screenshot attached for reference.

Has anyone else experienced this on a Lenovo LOQ or found a permanent fix?

Thanks!
