Just build a new rig with a:
ASUS SABERTOOTH Z77
Intel Core i7-3770K Ivy Bridge 3.5GHz
With a COOLER MASTER Hyper 212 EVO cooler. When I first booted up I got a CPU fan error and had to go into bios. I had to disable the temp monitor for the cpu fan. I seem to remember there was something like that that I had to do on another build. Something to do with it being an aftermarket cooler. Am I remembering correctly, that you have to turn off the the monitor or is there a problem?
Second problem is, after installing windows 7 64bit it's not picking up my lan port on the motherboard. It's flashing yellow. Is there a setting on the board I'm missing, or is it a driver issue? I figured those were all installed with Win 7, never had that problem before.
