[94_AcCoRd_EX]

I was using watercooling, but I'm not ATM. Its pretty easy, and I went with a custom setup. The pre-builts generally suck. Its easier if you have a mobo with mounting holes BTW, but there are work-a-rounds.

49* is just fine if your PC is stable. I wouldn't even worry about it. If you are just looking for slightly lower temps, I've had good success with SLK-800s and 900us. The 900 will be quieter if you use a 92mm fan.
