GPU Temps way too high....

I noticed recently that my GPU temperatures are running way higher than they were when I first installed my GPU cooler, a Zalman VF700-Cu.

Idle's about 60 degrees, it shoots straight up to 75 almost instantly under load, and never stops until over 90 degrees. I tested the card for artifacts using ATITool, and as the temperature goes up, within 2.5 minutes errors start to occur (not surprisingly).

I've reapplied the thermal compound, to no effect. The cooler is certainly bolted down properly and is in contact with the GPU core, so what could be causing these massive temperatures?
 
gpu? does gpu translates into cpu?
anyway, have you checked the voltage on your computer?

i lowered my voltage on my processor from 1.45 to 1.3, and the temperture dropped by 10c, even after oc'ed like crazy

and your computer should turn off automatically when the temperature gets too high

for instance i set it up so that when it reaches 60C, the computer turns itself down.

well, you might set it up as high as 70C or even more, but its bad for your core right?

have you overclocked your cpu or what? may be you touched the voltage by an accident
 
charles, hes talking about a gpu (graphics processing unit) aka video card, not a cpu.

Jet, his card wouldnt be at 60F idle, thats only 16C. Not even with the best heatsink could you get that.

Is the new cooler securly fastened to the card? if its not tight then there will be alot of air pockets in between the core and the cooler.
 
i think you're gonna need to remove the heat sink and fully ensure that every piece of you old thermal compound is cleaned off. then carefully reapply the counpound and make sure it is done so that there are no pocket of air under the heatsink. on a similar note my card was getting up to 90 degrees quite easily and still running fine, however, all i did was remove their thermal compound and replaced it with arctic silver 5, my temps dropped by 20 degrees
 
Lol, I was definately talking about my GPU (Graphics Processing Unit), aka graphics card. I wouldn't be running ATITool for a CPU now, would I? :P Anyway I tried reapplying the compound before I posted, if you think that's the cause I may try once more, and perhaps even try a different compound (I used the standard one included with the cooler).

The cooler seems to be securely fastened, but it's hard to know how much pressure is being applied, because the screws tighten completely, with not too much effort. I'll have a look at that possibility though.

PS. I was talking celcius temperatures. I think I'd need phase-change cooling to get temperatures below room temperature... hehe
 
ive heard that the thermal compound that comes with the cooler isn't that great, i would try getting some arctic silver 5 if i were you. theres a computer shop near voodoo lounge (dont say you dont know where that is lol) that stock it if i remember correctly. i think the shop is called computer warehouse or something like that
 
Haha of course i know voodoo lounge lol. It's always weird finding someone who has the same local knowlege as u on the net tho.

You're right it is called Computer Warehouse, i've been there many times. They even tried to fix my pc once when my raid0 failed (waste of money there lol). I'll check them out, probably a better bet than Maplin or than that little shop down the bottom.

I'm a bit dubious in believing that to be the only cause though. Do thermal compounds degrade over time?
 
they can degrade... they always have a use by date on the (usually anyway) also, it might be drying out. the only thermal compound ive seen in maplins is the classic white goo, and i've never seen any in computerbase either.
 
OK, I've just ordered a 12g syringe of Arctic Silver 5 from the US, for only £12 inc. p&p, I'm happy with that. :) I'm sure it's cheaper than I could ever get anywhere else, especially within the UK.
