I've just received my ZMAXdp and I have it running with dual opteron 246 processors.
It's been running for a week now and despite all the BIOS tweaks and HWDoctor settings I can find, I can't get the fan speeds to reduce from what sounds like a hairdryer at full pelt.
On the box it says "Quiet Operation with Silence Cooling System" - I have to disagree.
Anybody else had this problem yet?
