I have a PEP66 that I was using on my P3 800, but it won't fit on my new KT7A board.. and I really don't want to modify it unless there is NO better cooler out there that'll work on my board.. I will mod it, but only if I have to in order to get the best air cooler (assuming it's the PEP 66).. price isn't TOO much of an issue (I ain't payin $100 or something crazy like that for an air cooler).
