Can i hook up the cpu fan directly to the mobo? (I dont want to damage the mobo in the process.) Do i need that special 4 pin male to 3 pin female to 4 pin molex connector? Some ppl have told me u can hook it up directly as the yellow wire is not needed. My questions are would this thing work? Im not sure because the the orientation of the cpu cooler wires black/red/blue. The female end has only the yellow wire attached while the male end has yellow/black and red attached. I thought I was purchasing 2 these and what came in was a three pin male to three pin female with molex 4 pin. If my memory serves me in the past when I built a system I used a special cable that converted a 4 pin cpu fan to a 3 pin mobo connection and used the power from a 4 pin molex running off the psu so as not to damage the motherboard from higher power psu coolers. ![]() The motherboard has a three pin connector for cpu.

Sometimes, you won’t be able to use a 3 pin fan or a 4 pin fan with certain parts the connections just aren’t right. ![]() Meanwhile, 4 pin fan connectors are used with parts that will have high power consumption. MSI K8T Neo2 V1 Socket 939 with a AMD Opteron Model 175 with stock amd retail fan. The 3 pin connectors are better with smaller fans that don’t need to use a lot of power.
