Is my CPU really 52 deg C?

I have just built the next server for our comany and I am concerned about the reported CPU temps.  The motherboard is a Supermicro X7DVL-E and I am installed a Xeon 2.5GHz Quad Core CPU.  I am using the stock cooler.  When I ran Super Doctor III it gave me an alarm and sais the CPU was running at 52 deg. C.  So I removed the heatsink and relplaced the stock thermal paste with Artic Silver.  But there was no change.  Is this a normal temp for this CPU at idle? What can I do to bring this down?  Also, I can hold my hand aginst the heatsink and it does not feel warm.

That's high for one of the low-power Xeon's, but not too bad if it's the X3320 ==> which Xeon are you using?   The quad cores DO run hotter than the dual cores, but shouldn't do so when idling (When you say "... at idle ..." I presume you mean with very low (< 10%) CPU utilization -- right??

It is the Xeon E5420 model.  Yes, when idle I mean just sitting there 0-2% CPU utilization.  Is there something I can do to bring the temps down?  I'm not sure that replacing the heat sink and fan would do anything except make the computer quieter.  The fan blows hard and the heat sink is not hot to the touch.

The E5420 isn't a low power Xeon ... it's TDP is 80w, with a thermal spec of 67°C

52°C isn't all that bad for this (Quad cores DO run hotter than their dual core brothers) ... what's important is how high does it get under load?   If it's still under 60, then all's fine.   But I'd be SURE your cooler is tightly mounted --> and did you apply the Artic Silver properly for a quad-core CPU?  (This is done differently than for single or dual core models)
