My Z68 Gen 3 mobo/i7 2600K combo has been running well and has proven to be stable, so I've gotten curious to see what it can do.
I bought a Xigmatek Gaia cooler because it's cheap, decent, and just clears the head spreaders of my RAM. It was also available immediately and locally. A couple of days ago a pair of these arrived:
Cougar Vortex PWM
I'm not a fan of the color, and if I was one of those window-on-my-side-panel types I'd hate the way they clash, but they're great fans. The integrated rubber shock mounts are a nice touch, and the cables are even sleeved. Right now they're mounted push-pull on my Gaia, and with PWM enabled they move air more effectively than the stock cooler fan, at lower RPM, and more quietly to boot. I'll have to see if I can get away with one Cougar PWM fan to lower noise even more. They move so much air that the front panel on my Lian-Li PC-A05N is a major exhaust choke point (keep in mind this case's airflow is back to front). My CPU temps lower another 5-6C with the panel removed. It will have to be modified at some point. I removed the empty 5.25" bezel and that helps a few degrees too. At the very least I'll get the ventilated 5.25" bezel.
My case seems to do well with a top mounted blow hole too, and with the fan design on my overclocked GTX 560ti it doesn't exhaust fan efficiently out the back. Most of the hot air spills into the rest of the top of the case. It's running within temperature specs at 950MHz with 1.0v, but I'd like a bit more breathing room.
I have a 140mm
Cougar Vortex HDB ready to go when I'm ready to modify the top panel.
Anyway, even as things stand now, I've got my CPU happy and stable at 4.5GHz and 1.350v. I know that's far from bleeding edge, but I'm happy with the performance and heat. I'm not interested in exploring the outer limits. I'm pleased that the power consumption between idle and max CPU/GPU load is right in my power supply's efficiency sweet spot. My next goal is to see how much I can knock the voltage back down while maintaining stability in a battery of tests.
