I'm wondering how to get the temps down on my system. My i7 920 is running at ~49C @ 3.48GHz (166 x 21, 1.21v) and am thinking that could be a bit better. I've got a Titan Fenrir cooler using chill factor 2 in my CM690 with 2x120mm exhaust fans on top, 1x120mm exhaust rear along with one of those akasa PCI exhaust units and 1 x 120mm intake at the front and a 1 x 120mm fan at the bottom. The unit itself is under a desk (shown here). Any suggestions on getting this down?
