I exchanged some posts with an owner of a Swiftech in regards to this board and we came to the conclusion that the big Swifty would most likely NOT fit. The capacitors on the one side are too tall. Other than that I have seen posts of folks with a Thermalright SK-6 on it and I installed a Tai-Sol Ck 760092b (has the 30cfm fan& copper base) on it with no problem. Temps are excellent with the Tai-Sol with a 1.0 GHz chip. Don't know about others. I'd go for the Tai-Sol if you have a choice in the matter. It is rated for 1.4 GHz + . I am not sure if they still offer the 30cfm fan, but there are others.
