The goodI got upgraded processors E5-2680 v3's over E5-2670'sThe BadDead Fan and Dead 16GB module.Why the 4 stars:1 memory stick stopped reporting in after moving it around I got it to work, the fan was unplugged plugged it in and it seems a bit weak. I might add warranty on these in a day or two.The procs alone cost more than what I got these for, hats off on that.
