q9550 C1 Core temps very strange

I have a new rig I just put together, and I'm getting some very strange readings off of Real Temp.

First, my rig is a XFX 790i Ultra w/q9550 @2.884 ghz (very slight oc, for the ram) with 4gb (2x2gb) of OCZ 2000mhz DDR3 set to 8-8-8-16 2t at only 1.8v and 1.4v spp, @ 1900mhz, XFX Geforce 9800GTX+ Black, WD 300gb 10krpm sata300 hard drive. PC Power & Cooling TC1KW-SR (Pre-OCZ design), vista x64 sp1,

My case is the Xclio 1000, and I have a Zalman 9500 on the cpu, with arctic silver 5 installed per their instructions..

My issue is this...at idle, my core temps show 25 26 35 25. When I noticed this, the first thing I did was check my install on the cooler - took it off, cleaned it with arcticlean, reinstalled it...identical results.

It's stable for 8 passes of memtest 86+, and when I run prime95 under the torture test, it passes all 8 tests, but the temp difference doesn't change much...it goes to 41 39 47 38. I'm not planning on oc'ing the unit more than it is currently, I need this rig to last for as long as possible. (plus I didn't get the treasured E0 stepping, I even sent it back to newegg twice to try and get the newer version, no dice).

I know those are all safe temps, and below normal for many of them, but outside of lapping the processor and the heatsink (something I'm not comfortable with) is there anything I can do to get control of that one core? Or is it a faulty chip?

My CPU voltage is set to auto on the mobo, and I don't want to undervolt the processor.

Thoughts/Comments?

Hrm...I was hoping from some input or at least someone listing similar problems before and how they fixed it...

Guess I have to wait for Hard OCP to fix their boards...

It is normal for one core to report a relatively higher temp than the others. I wouldn't worry about it.

Download, if you don't have it already, Real Temp and run the sensor test. Check the offset and see if you have big difference between the sensors. It may be that one of them is stuck. Same problem here. I'm not worried abt it much though, as long as I get ~ok reading from the other three!
