CPU fan rarely runs

[dkev]

I have an Artic Cooling Freezer 64 Pro. http://www.newegg.com/Product/Product.aspx?Item=N82E16835185125 This sits on a Athlon 64 X2 6400. Is it normal for the fan to rarely run? Idle temps run around 80F. I was just curious if you guys encounter the same thing with your set ups. I'm about to upgrade to a quad core, and this hsf is compatible. I'm glad because I love this thing.

I should point out that it is motherboard controlled.

Well if your mobo tells it not to run then it doesn't run. Thats what PWM is. If you want it on a constant speed then plug it into a 3pin header.

does it run slow or not at all?
