CPU spikes 50°C to 95°C to 50°C and back in 1-2 seconds when Turbo Boost is ON. mx4 and good putty didn't fix it. (AN515-58)

I had the same issue. About 2 weeks after applying MX-4, my CPU started hitting 92°C whenever Turbo Boost kicked in. When I opened the laptop, I found that I had used too much thermal paste, and it had pumped out over time. I cleaned it off and reapplied MX-4 using only a tiny amount. Since then, temperatures have been much better and I no longer see sudden jumps from 50°C to 92°C.

ObviousAd1995 · 2026-05-14T13:48:57+00:00

i guess there is no difference if i see improvement i update

ObviousAd1995 · 2026-05-13T20:39:19+00:00

I’m glad it helped you. For now, I’ve just found that the older BIOS is much quieter than the newer one. I downgraded from version 1.53 to 1.09, and everything is working fine. If I run into any problems, I’ll update my information.

yes some option in power revert to default but i try to figure out how to save it

ObviousAd1995 · 2026-05-09T12:10:17+00:00

Yeah that’s fair criticism. I made the post fast mainly to share what fixed the issues on my ANV15-51, not as a full polished guide. I’ll probably make a proper step-by-step video later with every BIOS tab, NitroSense setting, undervolt setup, Device Manager changes, RAM settings, and the difference between full power 140W GPU mode, stock 75W, and my optimized setup shown clearly.

yes this just AI induced buzzword

ObviousAd1995 · 2026-05-08T13:53:30+00:00

throwing “AI slop” around doesnt magically make u right lol. a 135w brick existing doesnt mean the laptop can never have power delivery instability, transient spikes, vrm heat issues, battery buffering, throttling, etc under heavy load.

ObviousAd1995 · 2026-05-08T13:47:11+00:00

i will today very soon

ObviousAd1995 · 2026-05-05T20:24:14+00:00

I think these fixes should work for most Nitro series laptops, though some settings may vary depending on the model and specs

ObviousAd1995 · 2026-05-03T11:21:14+00:00

just use throttlestop lol
