I was looking into a closed loop liquid cooling setup for my CPU (i5-3570k) to keep my temps lower. They're already relatively low (40C idle, little high, and 60-70C under load at 4.6GHz), but the cooler, the better. I've noticed the HAF X would look really nice liquid cooled, it's got lots of room and a really nice design. My top exhaust is a 200mm fan and it's got an additional 200mm slot next to it for future customization. I was wondering if I could get a big enough radiator to take up both slots, or just get the H90 and use my stock HAF X fan to keep the Blue LED. I'm usually pretty savvy with computer parts, I built my own, but water cooling has always been a little confusing to me.
