I got a brand new Gigabyte Radeon 6870 Overclock Version but I'm worried about its temperature, I was playing SC2 on high settings and the graphic card temperature rinse up to 89 celcious. I think it's TOO HOT.
My gaming case has one 120mm fan in the front, one 120mm in the back and a huge 220 fan in the rear so I don't think ventilation is the real problem.
What can I do to lower the temperature? or it's normal for that card to go that high on the temperature?
the HD6870's max out at 105c, however you should hope to never see those kinds of temperatures. Do you have a blower type graphic card cooler, or is an aftermarket type design with multi-fans and blows the hot air into the case instead of out the back?
However 89c does seem a little hot, if your comfortable you may want to remove the cooler and change the thermal paste
If you don't mind fan noise, try using MSI Afterburner to set a custom fan profile. I find that the default fan profile isn't sufficient to cool my 6870, causing it to hit about 90 degrees at full load. So I bump up the fan profile to run at 60% speed at 60 celsius, and go up 1% per degree from there, brought my full load temp down to 72 celsius.
Yeah, if you are still hitting 92 with a more aggressive fan profile, that could mean the thermal paste wasn't applied properly, or your case has airflow problems, which it shouldn't with the fan setup you have.
Adding a case fan is very simple, you just screw the right size it into the case sockets. Sometimes the case isn't threaded, but that's pretty simple. Redoing the paste can be your second go around, though if there is a sticker there it will say something about if you remove it you void your warranty. If you would rather ship it in than risk having the vendor not honor the warranty I would ship it in.
I gave a call to the vendor and he said that I could take the video card to him to see what's wrong, so I'll do that first, if for some reason he refuses to validate the warranty I will try with the termal paste thing.
