NZXT Kraken X60 280mm Ultra Performance Liquid CPU Cooler $99.99 @ newegg
competes with Corsair H110 (very similar Asetek units. ~1mm difference in rad and different fans).
COOLER MASTER Seidon 240M $79.99 after $20 rebate @newegg
I would recommend and save up for a Swiftech H220. Expandable pre-build custom water cooler
setup. you add your vide card(s) later on into the loop. Swiftech has been building high end water coolers
for over 10 years now.
high end Air Coolers are cheaper and most CLC can't beat them. They might be 1 or 2 deg cooler but much louder.
H100 hits 59 dBA when fans are at full speed.
