I'll make this short and sweet. Yesterday after work, I installed my Q9550 and I put the Thermalright TRUE Black 120 Extreme cooler with 2x Scythe S-Flex 1600RPM fans. When I booted up, the POST screen said "CPU Fan Error, press F1 to resume". When I plugged up my cables, I only connected all the molex's on the 2 fans but I didn't plug in either connector into the CPU Fan connector on the board. The other thing is, in CoreTemp and RealTemp (this is pretty weird). My idle temperatures in CoreTemp is 47, 47, 44, 46 and RealTemp says 27, 27, 24, 25 (stock speeds). This is pretty weird. I don't think CoreTemp is right on that one. Thanks.
