These new servers run really cool compared to the the older Xeons,
Also the machine is in a Sungard Data, where temps are very cold

The machine did have IPMI card in it and I could monitor temps and that 
reported hold, I
 also set the fans to full speed just in case.

Apparently, the new FB-DIMM memory gets very hot, however, I know 100% 
that this is not memory related, because the previous week I had to 
replace 160G of FB-DIMM memory in 10 servers because of memory problems, 
which was approved by Intel (on intel web site - only 5 companies are 
approved).

(I won't name the company because the admitted the problem was there RAM,

Supermicro, then got me 160G of ram and tested it all before shipping it 
to me, and that fixed the RAM errors.
