I had overclocked my cpu last night and before that my cpu temp was 33C Idle Avg. After the clock my cpu temp is 34C Idle Avg. I was thinking of a way to chill my water but had no reasonable ideas for my budget. So i found an old HSF and thought if i could pass tubing through it, it would chill it :P a bit. So i bent a path through the HSF to fit the water tubing. Then put the fan on and did some case rewiring/rerouting. I turned on my comp and my temp is now 28C Idle Avg. Just thought id share.

The HSF is a Volcano 5.
Overall this is a cheap and effective cooling solution.
