kaupo1 :
Thanks! i want best cooler for oc
Are you saying that you care about heat dissipation the most and don't care at all about anything else including noise and your case has room for any of those?
Oh, I don't know much about the ones you've mentioned but from what I have read the OCZ vendetta II is good and at a good price.
Anyway hope you find some benchmarks and figure it out or someone who has one of those personally sees your post.
