Just thought I would let everyone know I found a sweet GPU cooler for MDD macs. Its made by Vantec-the all in one coppery kit "CCB-A1C". Its less than $10 from New Egg.com and comes with a beautiful heat sink w/fan, and two chip coolers for motherboard controllers. There are others but this one is definately worth a look! :lol: LET THE OVERCLOCKING CONTINUE!
