Lower X300 CPU Temperature / Thermal Grease
Posted: Fri Feb 27, 2009 1:10 am
Hi.
My X300 has always run a bit hotter than I would like. Recently, even keyboard bezel would burn whenever the CPU was pegged for a few minutes. RMClock and SpeedFan reported the CPU temperature at over 80C at load, and an idle of around 60.
I tried replacing the existing thermal grease with Arctic Silver 5 a few months ago, but that didn't lower the temperature. I did some research, and it seemed that laptop heatsinks can have poorer contact than desktop heatsinks. So I tried again, but with a much larger larger gob -- about 3 grains of rice worth. My temperature is now at 58C load! That's over 22C drop in temperature. It's shockingly cool now.
Hope this helps others with hot X300's.
Cheers.
