Solved CPU Fan Pin Compatibility Tags: Homebuilt CPUs Compatibility Systems Product Last response: April 21, 2012 8:04 PM in Systems Share MrKopaka1016 April 21, 2012 4:38:01 PM Hello people of the System forums. So I have been wanting to get a new CPU fan to replace my stock (it is loud loud loud) and i found one to seem to be the one. http://www.newegg.com/Product/Product.aspx?Item=N82E168... How ever i have run into a conflict, I checked my mother board has a 4 pin CPU fan connecter and not a 3 pin like the fan I have found requires. So my question is will it fit with one pin hanging lose. My Specs are in the signature. Thank You!

It can be controlled with adjusting voltages if your bios supports it. m 0 l Can't find your answer ? Ask ! Publish Related resources SolvedWill a 4+4 CPU pin work for an 8 pin socket?
