The card hits +90c easily while playing Just Cause 2, which makes the fan kick in. The entire play session is just the fan continuing to work as hard as possible to keep the temperatures down. What gives? Did I just pay $320 for a loud fan? Any suggestions to this problem?
Can't escape the fact that GTX470/480 are hot and loud cards given their inadequate cooler + large die size. If noise is really a concern, 5850/GTX460 would have served you much better.
However, as I suspected 2 main things are at fault (as is almost always the case with every 470/480).
#1 - You have your fan set to Automatic. No wonder it's ramping up to 92%. You know why it does that? Because running automatic fan profile means that the card takes too long to adjust fan speeds to deal with the hot air. Then once the temperatures rise too quickly, it has to ramp up from 40-50% all the way to 90-100% to deal with the sudden heat.
This is why a manual fan profile is crucial for 470/480 cards. Make sure your fan speed ramps in EVGA Precision Tool or better yet MSI afterburner from 50*C to 80*C. Manually connect the fan speed line from 40% fan speed @ 50*C to 75/80% fan speed @ 80*C. This way your card will ramp up fan speed
much more aggressively and not wait until the last minute when it's already overheating resulting in massive 92-100% fan speed rampup!
#2 -
More importantly, your case has inadequate airlfow. A tiny 80mm top exhaust fan and the same small 80mm back exhaust fans. So you have 0 front intake fans, 0 side fans. How do you expect to have any airflow in your case? You are losing
at least 10*C right there to cases such as Antec 1200, Azza Solano, etc. I am not kidding when I say that. I got rid of my old Thermaltake Soprano case for the Azza and my CPU temperatures alone fell 8*C on the Megahalems. I can't imagine running a Fermi card in such a case.
I've no idea how to max volt the card. Idle temperature gets to 52c, so I'm guessing airflow is the culprit here (40% of the fan speed going--can't hear it though).
My EVGA GTX470 only idles at 38-41*C at 33% fan speed. Here you go - case airflow is for sure one of your major problems.
#3 - You are probably running stock Intel CPU cooler too. If that's the case, even more heat is trapped in your case. Most systems with 470/480 cards probably have setups where the CPU cooler has an fan which is eitehr aimed at the top of the case with its own external exhaust fan or at the
back of the case with at 120mm fan. This way the heat from the CPU is also exhausted from the case, which isn't the case for you either. The hot air from the CPU being trapped inside your case is only exacerbated by problem #2.
Once you set a manual fan profile, things should be much better. However, you won't have <80*C temperatures in your case without high noise levels.
The cheapest and most effective way to lower your videocard noise and temperatures would be to grab a GPU cooler like Zalman ZF3000 or similar.
This is probably the most effective method. I'd consider adding case fans too if you have the budget for it. Otherwise, just sell the card on Craigslist and pick up a 5850
