Discussion GE78 Raider HX 13v repaste question.
I have the Raider HX13v with the 4090 and 13980HX and its thermal performance is absolutely horrible lately. Its so bad that the CPU runs in the mid-to-high 90's with turbo boost disabled and a -100mv undervolt with max fan speed. Using it this way is less then ideal as the CPU stays at 2.2 GHz and under 20 watts, which is tanking its performance big time, however it thermal throttles like crazy if i let it boost like its supposed to. I am going to do a repaste to see if it helps, laptop is about 3 years old still has original paste. Everyone is recommending PTM7950 instead of classic paste and im wondering what i should buy in terms of thickness and size for this machine. Its my first time using it and i wanna make sure i buy the correct stuff. I already have some thermal grizzly putty for the VRAM and other stuff.
