Excellent little radiator. I have never been dissapointed by a DD rad, they are top quality. I have one of these on my server, cools northbridge, CPU and an old X700 vid card to 45-50C in a 75-90F utility room. I use 2 low speed long life 92mm fans with about 50 CFM each. If you are looking for a small high performance rad this is it.
