I completed my new build last week and have since been scouring the web for info on my components. More recently i've been scrutinizing over my CPU temps before I OC.
I read through the temp sticky, but am still a bit lost. Are there temps ok:
85 C ( TJunc) by Core temp 0.95
37-39 C for cores by Core Temp 0.95
41 C Asus probe
Load: (Orthos, small FFTs after 45 min)
56 C Core Temp 0.95
61 C Asus probe
The reason I ask is because it is just now that I am seeing a lot of post complaining about the Scythe Ninja Rev B and it's contact to the CPU. I want to OC the machine, but I want to make sure all is ok with HS and CPU before I start OCing.
If my setup isn't ok then I'll have to look into getting the bolt on retention kit, or go all out and do water cooling before I OC.
Specs not in sig
E6600 / Asus P5N32-SLI / EVGA 8800GTS (320MB, no SLI yet) / Corsair XMS Dominator DDR2 800 / 3X WD2500YS / Scythe Ninja Rev B w/Ixtrema 120mm@72CFM / Antec P180
According to Intel's spec sheet, you don't wanna exceed 60 °C under load. Try RMClock for your temps, it should read the same as coretemp. Anything else you're using like the asus utils aren't as the same.
If you're concerned about your temps, you should know that all C2D and quad C2D chip are known to have irregularly shaped IHS (internal heat spreaders) meaning good contact between the HS and core can be difficult. You can consider lapping both the base of the HS and the IHS on your chip to give better temps. I knocked 7 °C off my load temps from the coolest core and over 10 °C off my load temps from the hottest core by lapping both the IHS on the Q6600 and the base of the ultra-120 extreme. See pics and temp graphs in those two threads.
Yeah, the Tj is what has me concerned. It may be the HS or the CPU heat spreader, don't know until i try lapping HS. But I'm not going to lap anything until I get the bolt-on retention kit. THOSE PINS ON THE LGA775 SUCK A$$!!
My only other options are to water cool the thing. (I tossed the boxes out yesterday, so RMA is a no go! :x )
One other thought, my MB is slightly concave (looking from top), could this cause a prob with CPU-HS contact?
I installed my sythe ninja today (and have now sussed the no cpu fan problem - any fan can run off the cpu fan plug (duh)).
I'm getting about 50 to 54 on each core (according to coretemp).
This is at stock speed and no cooler than the stock HSF.
I'm using the thermal goop that came with it for now, because I forgot to order any branded stuff when i ordered the HSF.
I think its due to uneven contact too, but i'm going to now see how OCing will affect these temps.
You don't need to worry about Tcase. As I understand it, there is no Tcase sensor; the values displayed are hypothetical/extrapolated and highly inaccurate.
You DO need to worry about the real temps in the physical cores. Speedfan measures these core temps from Intel Core array (in addition to other sensors on your board). Other apps measure core temps too like coretemp, tat, and rmclock. Problem is by quad core CPUs, speedfan's coretemps off by 15 °C because it needs to subtract 100 from the DTS number to arrive at the core temp, not 85 which is what it uses. I think it should be accurate for C2D chips.
Do this: download RMClock and compare the numbers to speed fan. Are they the same?
[code:1:81aed2bfaf]Core temp = constant - DTS where the constant is either 100 or 85 depending on your processor.[/code:1:81aed2bfaf]
If you want convincing proof, read this thread paying attention to uncleweb's instructions to read your DTS directly with crystalcpuid. You'll find that RMC is accurate.
