Thanks. I didn't buy the water cooling system because at the time I bought the i7 cpu (last year after it just came out), there weren't any blocks that could accomodate the socket at the time. After which, I bought the noctua "conventional" cooler instead. It works great, but it's HUGE (as in high), and I can't use the original cover that came with the case (with the 120mm fan on the side).

I'm sure there are [water] blocks that will fit my socket now, but to tell you the truth, I haven't been looking around for one since I'm not ready to buy one just yet.

ps - the noctua, although not the best looking, is amazing (in terms for thermal performance).
