Fan speed not increasing automatically?

[Waylay00]

So I was playing Empire Total War on my new rig (i7, 650w Corsair, XFX HD4890), but I noticed that I got some artifacts after a while. Opened up GPU-Z and saw that my temps were around 67C. However, I also noticed that the fan speed on the GPU had never risen above 34%. When I manually turned on the fan about 50%, the artifacting went away.

Why is the card not spinning the fan enough automatically when it should be?

If it's artifacting at stock speeds/fan settings then I'd return it and get another one (if it's easy to do so).

If it was only 67C, then the fan was spinning fast enough. That's not too hot, and you probably shouldn't see any problems at that temp.

Yeah, I don't think you should be artifacting at that temp. That being said, I just got a new system as well (similar to yours) and am using Win 7 RC, and the fan does not auto adjust at all. I tried furmark recently and the temp went up to 78C with no fan adjustment heard. Finally download Catalyst software and adjusted fan speed to 35% and now it rarely goes above low 60s. Any higher than that and the fan is LOUD. I set it to 100% just to see how it did and my computer almost took off. Wow.

67C is not hot for a GPU at load. My guess is that it is defective.
