My GTX 550TI runs at around 40c idle and after playing Black Ops for about half an hour, the temperature was 67c. When I stress tested with Furmark however, the temperature reached 90c. When I turned the fan on max, it went down to about 85c. Is it running too hot?
I suppose my case cooling could be better... I have no case fans, cable management isn't too much of a problem I don't think, all my cables are at the bottom. I've read that hot air rises, and there are unblocked ventilation holes at the top. And it is a mid size tower,not a very big case at all.
I would add some fans. I've got an Antec Sonata with close to no airflow except for 2 case fans. One blows hot air from the hard drives into my graphics card and one is connected to my H60 watercooling. My 460 never goes above like 75C.
Do you have MSI Afterburner or EVGA Precision to change the fan temperature?
Intake fan at the bottom front to suck in cold air, exhaust fan at the top rear to pull out hot air. This is the minimum I would recommend for any PC with a discrete GPU. Fans front and rear create a nice airflow through the case and will lower your temps significantly. A single side fan will not help you in this case.
Your CPU fan will not create airflow since it blows down onto the heatsink; i.e. if your fan points toward the rear, it is actually sucking air FROM the rear. Unless I misunderstand and the fan is at the front of the heatsink relative to the rear of the case?
Either way, a fan a the back is never a waste of time. Most of the hot air will tend to move to the top and rear of the case, and a fan there will help get rid of it.
After putting in a case fan, There's a bit of a difference normally, but when I turn it to 100%, my temp doesn't go past 75 in furmark, compared to not doing much of a difference before I had this fan in.
