The "gpu cooler" would be the 2 fan thing But some are better than others. You'll probably have a lot of headroom to turn up the fans though, if you don't mind a little more noise. I'd say use MSI Afterburner and set a custom fan profile. Also your case has pretty decent air flow. You can probably help a bit by making sure you have all your wires tucked away so there's not much interference for the air flow to the gpu.
I don't know what you mean my "what gp should I use".
Sorry meant gpu cooler.OK yea as you can see im new to computers.So i could buy a better gpu cooler and take off the one that came with it?I use trixx.But I have noticed it only works with the extra fan a put in myself?
Yes that temp is normal, GPU's are amazing and can handle temps up to 100c. My 6970 gets up to 70-75 c. However I have the NZXT Phantom and it moves a hell of a lot of air.
80C is fine. It's hot, but not that hot. There should be a way to make the GPU cooler fans run faster. I've never used TRIXX software, but even in CCC you can set a fan speed.
