The HP Notebook 247 G8 is overheating and shutting down. Is it just the fan? 90B or 90D warnings too.

Laptop specs: HP 247 G8, Ryzen 3 5th Gen 4-core/8-thread U-series, 8GB RAM, 512GB SSD, Vega 6, 14-inch. Bought on 25th Dec 2022.

Hey guys,

I have an HP notebook that I mainly use for 1-2 hours of YouTube/courses and around 8 hours of WFH. [used to use for coding (VS Code), (SQL cmd), (Python cmd), etc., and a lot of gaming and YouTube]

Now in 2026:-

  1. It started showing temperature/fan warnings, so I took it to a local shop. The tech cleaned the fan with a brush in front of me and didn't charge me anything. After that, the warning disappeared, but so did the fan.

  2. I went back and complained that the fan had stopped working. After checking it, he said the fan motor was severely overheating and had eventually failed. Since then, the laptop shuts down once it reaches a certain temperature, kind of a thermal fail-safe.

  3. I even keep the AC at 20°C while working and already bought a gaming cooling pad with 6 fans running at 2900 RPM, but it still overheats and shuts down. After repeated shutdowns, Windows even locked me out for 2 hours.

  4. On battery, it keeps getting hotter because the internal fan isn't working and eventually shuts down. If I leave it switched off and just charge it, there is no issue. But as soon as I use it with the charger plugged in, it heats up and shuts down.

  5. I don't think there is any performance issue with the laptop itself. It seems like the cooling system has simply given up.

I had installed Linux a while back (2024) when everything was working normally, and it ran really smoothly with no lag or jitter. No gaming on Linux, so I eventually switched back to Windows. (2025)

I contacted HP Support, and they told me to visit an HP Service Center, where apparently I can get the replacement fan for a reasonable price.

I'm really hoping it's just the fan and not the entire cooling system. I used to play games on this laptop, so the fan would run continuously for hours.

What do you guys suggest? Is replacing the fan likely to solve this, or should I also be worried about the heatsink, heat pipes, thermal paste, or something else?

Thanks!

What's your user experience been since you bought your NS400Z?

Hey guys,
I bought my dream bike in MY26; Apollo Tyres are from APR26. (Got Riding Jacket free and one basic ISI helmet)
I have crossed 2.1K kilometers on ODO, and I feel completely satisfied and have no regrets whatsoever.

I just want to hear what others have to share about their NS400z.
Whether you are planning to buy or don't own it, it doesn't matter; just share your thoughts and views.

What I've noticed so far:
She stalls and misses if I use E20, which I did once and never again.
She drifts to the left, which I have reported to SC, and they told me that they will be fixing it in the next scheduled service (2nd service)
I prefer to clean and lube the chain myself, so not having a center stand makes things difficult.
Due to my own fault, the oil level came down, so I visited SC to refill freaking 200 ml.

Suggestions required! (She is stock; no changes or upgrades whatsoever.)
I plan on buying the NS200's center stand, as I researched everywhere thoroughly, and it is a perfect fit and sits just a bit above the exhaust's height and doesn't scrap.
But many of my friends suggested getting a portable jack stand, which is easier to carry and doesn't ruin the NS400Z's look.
I'm confused about what my next necessary mod should be!

What is the highest speed you have achieved on your NS400z to date?

I reached 120 km/h for 2 seconds in the early morning on empty roads.
I just wanted to know if you are able to reach its top speed or not.

Official numbers are 156 km/h for the 349cc variant.

Unexpected Mileage figures

I have been surprised by the fuel economy of the NS400Z. Before buying it, I thought a higher cc bike (349 cc, 2026) would easily return around 15-20 km/l, but I was completely wrong. Even with mixed riding like stop-and-go traffic, highways, and monsoon conditions, the bike is giving me much better mileage than I expected.

I have been riding mostly in Sport mode lately, and the instant acceleration makes the bike so much fun to ride. At the same time, it hasn't been as fuel-hungry as I initially thought. I don't rely on the bike's mileage display. I calculate the mileage manually after every fuel fill (distance ÷ fuel filled) and also keep a record in an app. I trust my manual calculation more because the app sometimes shows slightly lower mileage. Also, please ignore the fuel prices shown in some of my entries (the attached screenshot is only for your reference). I didn't update them correctly and just entered an estimated price for Power Petrol, so those numbers are not accurate. The mileage calculations, however, are based on the actual distance and fuel filled.

I also lubed the chain myself for the first time. Without a paddock stand it took me almost an hour, so I think a paddock stand will be my next purchase. I would love to know what mileage other NS400Z owners are getting. Please share your riding conditions too (city, highway, mixed, pillion, etc.), as it will be interesting to compare.

FYI: I live in Navi Mumbai, and I use my Access 125 SE daily for office commutes, which returns a solid 58-60 km/l even with E20 petrol, and the NS400z is for weekend rides. I put a parking cover on her and check on her daily to ensure she is as fine as the day I took the delivery.

Mods: None so far.
Top Speed: Reached 110 km/l once, but the traffic greeted happily.
Current ODO reading: More than 1200 km.

Feel free to ask questions; I'm more than happy to reply.
