I have an EVGA GTX 470 that I am going to be repurposing towards BOINC usage (protein folding) 24/7 (when i'm not gaming), and am worried about the card overheating. my case has plenty of cooling, I am not over clocking anything, and there is plenty of ventilation out the back. I just worry about accidentally killing my components.
The specs are:
ASUS Sabretooth x58 motherboard
Intel Core i7-950 (stock heatsink/fan)
6x 2GB PC-1333 crucial ram modules (no heat spreaders)
EVGA Geforce GTX 470
NZXT Gamma classic series case
Seasonic M12II 620 Bronze PSU (replaced my cheap-o power supply from the initial build that fried itself)
Those cards get pretty hot. I'd recommend creating a custom fan profile (not sure how for Nvidia, I'm an AMD guy) to be sure it's cooling more than it normally would. Your goal should be the lowest temps possible without making your computer sound like a lawnmower. It's not like you're going to fry the GPU from doing this, but running at high temps 24/7 will give it a much shorter lifespan due to the stress.
You can use an older version also, they all can be used to create a fan profile.
Did this, was not aware the fan could rev that high. reset to auto and i will now be trusting my machine to not burn itself out.
bad experience with cheap power supply makes me hesitant, but everything seems ok.
