6831fx GPU overheating

Hi guys,

My 6831fx recently shut itself off during cod4 (20 minutes into it). This has never happened before. After cleaning the blanket of dust that was clogging up the GPU intake vent(bottom) I propped the back up with a stack of post it notes on each side and fired up cod4 again. I checked the temps (HWmonitor) after 20 minutes and my GPU was up in the 93-98C range. Is this normal? I don't recall seeing my temps this high up into the 90s when I first got this laptop last march. The GPU idles at high 50C+. Do I need a notebook cooler? Are notebook coolers even effective at all? I've read many different results ranging from 3C drop to 15C drop n i would like to make sure it is worth it (temperature wise). Thanks in advance!

 

its not normal, i dont get more than 70 on cod4.
mine idles @ 40-44.

get some compressed air can and blow that dust away. if you were doing fine until now, no reason to get a cooler. i use zalman nc-1000 and as far as gpu cooling goes, it does little more than propping the back. it does help with the hdd usually about 10c cooler.

 

sorry noob question...I don't have access to the GPU fan do I just blow the compressed air into the side vents? How do I get access to the the GPU fan itself?

 

you cant without taking the whole thing apart.
just blow through the bottom and the side until you think its clean, no magic tricks here. do make sure it doesn't drip inside.

and do feel free to ask all you may think of (but do use the search as well )

 

Thanks royk! +rep

 

stay cool
