Overheating issue

[Sinny]

Long time since I've posted in here, but due to money problems I've been unable to upgrade my PC in years.

Anyway, I've currently got an Inno3D 8800gt and for the past few months after a while maybe playing a few games or watching a films (sometimes just the screensaver on) my screen will go completely blank yet everything still runs in the background, now after being dumb and not knowing I think this is most likely an overheating issue as I've just touched the heatsink and it's scorching.

It's a slimline one so naturally will get hot, however I can't afford an upgrade so the cheaper option would be to get a decent heatsink solution.

What would fit my 8800gt and more specifically what is the best in terms of keeping it cool?

cheers

Hello Mate

My cousin had similar issues with a Gainward 8800 gt - there is likely a dust build up under the cooler / across the heatsink casuing heat to buid as air is not circulating properly. You might not need a new cooler just a good clean.

First thing to try I would suggest only if you know what you are doing
Take off the cooler and clean off any dust - compressed air is the easiest way.
You can do this with the cooler on but you dont get it all out.

Then clean of the Thermal Compound - with say TM cleaner, always good to own a bottle lasts years - then replace the TM compund with say Arctic Silver or any similar Thermal Paste.
Check online for the best way to put the TM on the chip.
Arctic Silvers website is very good for giving instructions on the right application for which chip

Will cost very little £12 but should put life back in the ol 8800 GT

You will need to do most of this anyway to change the cooler

Cheers mate, Will give it a go!

I've got an some arctic silver left somewhere, go and root it out and see if I can solve the heating issues, will report back when I've done it (and found my earthing mat).

worth a try mate, stock cooler was working fine until recently and fan pushes air as long as its spinning itsa moving the same amount of air!!

Dust builds up over time especially in the tight fitting slimline cards, they are also hard to compress air it all out

Did a Furtest, which crashed the pc after getting to 106c!

but that was a major stress test, SC2 worked fine. and I don't have to wait 5 minutes for it to cool down now when I restart so hopefully fingers crossed! .

I took the Thermal pads off as well (good idea?) and put thermal paste over where they were,

Thermal pads are usually a lot thicker than a layer of thermal paste.

You need to check if the components with thermal the pads on are now actually making contact with the heatsink.

They may just be sitting there with an air gap between them and the heatsink.

I'll buy some more just in case. only cheap.

Just ordered the Akasa from somewhere else as overclockers don't have it in stock, I'm getting bluescreen when I play a few minutes of HD youtube video, I've stress tested the CPU for 30 minutes so that isn't the problem, it's idling at mid 70's so I guess it needs some nice new HSF, only problem is I hope it fits as I've got my watercooling pump screwed the the bottom of the case and it's quite close.
