I have re-seated the cooler, tried a different cooler,tried both AC5 (my usual) and Thermalrite chill-factor paste. In fact, I even have 2 cpu fans (push-pull fashion)running at 2,000rpm each. The problem is not cooler or paste application related !!
This 14-15c temperature is surely a problem. This problem is just that "one" core. Notice how low my cpuz Vcore is; at that low voltage with this cooling, I should think my temps should be in the mid to high 50's maximum. I even had the case open for these screenshots.
If I drop the OC to 3.6ghz, that "one" core still reads around 60-62c. Even at idle, there is a 41-34c (7 degree) spread.
Would my problem be mobo, CPU or something else??
Please help !

It certainly does seem odd that one core's result is so different. After some research, this could be HSF related, but you pretty much ruled that out... | |

| Re: Q9650 Temperature problem Yeah, one core being MUCH higher than the others I'd think HSF or at least the contact with the HSF...
It seems to be normal for these core 2 quads (both the 65 and 45 nm parts) to have 2 cores warmer than the others.
Here's my Q9550 @ 3.85 GHz idle:
floyd@pflog:~% sysctl dev.cpu.0.temperature dev.cpu.1.temperature dev.cpu.2.temperature dev.cpu.3.temperature
dev.cpu.0.temperature: 28
dev.cpu.1.temperature: 28
dev.cpu.2.temperature: 24
dev.cpu.3.temperature: 24
Notice the 4 C difference between cores 0/1 and 2/3, and the difference is greater when under load. As a matter of fact, one core in my case IS appreciably hotter than the others by 11 C (versus the OP's 15 C).
root@pflog:~# sysctl dev.cpu.0.temperature dev.cpu.1.temperature dev.cpu.2.temperature dev.cpu.3.temperature
dev.cpu.0.temperature: 47
dev.cpu.1.temperature: 38
dev.cpu.2.temperature: 38
dev.cpu.3.temperature: 36

1 edit | I've never seen such a thing, and it sounds a bit fishy. What indication is there that this isn't a software bug in Real Temp or possibly Windows (depending upon how the data is being fetched).
Also, have you tried *not* running multiple monitoring applications at once? I know that in the case of RMClock, SpeedFan, and some others, using them all simultaneously can result in incorrect results or error messages from the programs themselves (the reason being they're "fighting" over getting statistics).
Is there any indication the author of Real Temp has gotten in contact with Intel about this? If accurate, this would fall under "CPU bug" due to the thermistor equivalent being on-die.

| Re: Q9650 Temperature problem Well koitsu, it may sound fishy and it may be a CPU bug, but numerous people have a core-temp spread, just not so drastic as mine.
I don't run simultaneous temp-programs, but pictured so in order to confirm readings and conserve space. This should "probably" assure that neither program had a bug. I use the same real-temp version for my other pc's and I trust it; at least as much as ANY software CAN be trusted.
Your post of core temp is only at "IDLE" 2.0ghz with a 6 multiplier. Not really an appropriate comparison to what we're discussing here. Probably EIST or similiar has kicked-in due to idle. You will never show much disparity unless you're "overclocked" and under full-load...and perhaps you are one of the lucky ones (I hope so) 
I run REAL full-loads 24/7 for distributed computing, not occasional full-loads. An equivalent might be like prime95. Even my Q6600 spread at 3.4ghz is 2c degrees at idle and 6c degrees at full load. That's easy to live with, but LGA775's at 45nm seem to be much worse.
As 45nm prices decline, more folks are buying and noticing this temperature disparity. Indeed Intel should be very aware, but who knows whether they are addressing the issue. These things are like errata; they tend to remain concealed.
Anyway, I hope no one else has such a bad spread as mine

| I've got a 6600 and found odd temp readings via various temp monitoring utilities.
One of the most interesting ones showing my cpu fan to be running at 30,000rpm!
Have been using realtemp. Found some technical info for it here »www.techpowerup.com/realtemp/docs.php
hopefully this link might be a useful read. | |
