PC Heat Problems? Please help! :D

[Punto]

Hi there guys, running an Asus A8V Deluxe with an Athlon 64 3500+, had my setup for nearly a couple of years now, basically the problem is that over the past 2 or so months, whenever I try to play any games or do anything such as virus scan etc basically (in my estimation) anything that places an additional load on the cpu my game will get blocky and my pc will shut down (must be a heat issue right?)

My GFX card is a galaxy glacier 6800GT, that's at 69C idle, is that ok?

My MB idle temp is 23C but my CPU idle temp is 53C, far too high right? The load temperatures start shooting up past 70C. I've basically avoided using the pc for anything apart from browsing, had exams so haven't had the time to look at it properly until now.

I've tried reseating the heatsink a couple of times and it really does seem flush, could simple misapplication of the thermal compound be enough to produce temperatures of this magnitude (55-75C?). My cpu fan is running at 2900RPM, it's the stock cooler, connected to my mb via 3 pin.

I've just ordered an XP-120 and a Panaflo 120mm fan, as well as some Artic Silver Ceramique.

Just wondering if anyone could tell me why it's running so hot? I don't understand how the stock cooler could produce such high temperatures if the ambient temp is so low (mb temp is only 23C remember?)

Btw all these temperatures and recorded with Asus Probe.

Thanks for reading and any help would be much obliged.

Yeap.. 70C should warrant a shutdown, the system should throttle when it hits 70s.. I guess its either those thermal pads are getting flake-ish, or its a duffed temp sensor..

Try to Prime the system or Burn K7 it, then touch the HS to see if its really that hot.. u can tell whether its really 70C or just plain warm..

If ur chips one of those earlier models, the pads that come with stock coolers wont be Shinetsu.. that might just explain why.. Just rip the sink off and clean the old stuff off.. apply some Ceramique ot MX grease.. AS5 if ur fluent with it.. then lock it back in..

If its not hot at all, u might want to try updating ur BIOS see if it corrects the calibration.. Or just set shutdown temp a little higher (risky for newbies.. but if u know wat ur doing then its fine..)

The GT is going way too hot as well.. 69C on idle would probably mean 90ish during load.. are u getting any artifacts? Just a comparison, mine never hits 65C even on heavy heavy load at 440Mhz/1200Mhz... Again.. same thing.. either duffed temp senser, or dodgy thermal compound.. Unmount the stock cooler.. apply some new compound and lock it back in.. If u have cash, get a NV silencer or VF700 instead.. way quieter..

the galaxy glacier already has an nv silencer on it i think...

Hmn.. In that case, just reapply the thermal bit..
