Q6600 cooled by thermaltake big water 735? good or bad?

will a themaltake big water 735 cool a q6600 cpu efficiently? i have always hand picked my parts for my water cooling kit, but my brother does not want to spent the money on one and someone wants to sell him a brand new TT big water 735 kit. for 50 bucks. i never used one of these so i can't tell him if its good or not. what do you guys think? a Q6600 to much for it? also i heard the pump go out fast. one more thing will it cool the cpu and chipset?
