I have been listening to my fan dying. Getting louder all the time (shot 
bearings or bushing or whatever it has). So I know that my old was turned.

And the unit ran hot.

Now with the new fan in, it is not turning at all, but the unit is 
actually cooler than before, but still hot to touch. Could be better 
contact with the heatsink.

Either I put the power connector on backwards (the manual's pic is not 
clear on this, but I don't know if that connector CAN be put on 
backwards), or there is something with the bios with this new fan...
