E6600 36C on stock with Zalman 9700 and AS5

as the title says I'm using Coretemp for readings, I want to know if it is normal?I what should be normal temp?this is stock speed, no OC

my case is CM830 2 fans blowing on the side 1 exhaust at the back and 1 at top of the case and 1 fan installed on the HD cage...what do you think guys?my mobo is Asus P5K Deluxe

What is your ambient room temp?

Im using that same cooler but i used the Zalman thermal grease and a P5B deluxe with an E6600 and my idle temps were around 22 to 23C at stock speeds according to Coretemp

My ambient room temp is around 73F (its a basement room)

and as been discussed extensively in another thread, it's entirely possible the low end temps everyone throws around here are wrong by as much as 8-10 degrees

but as mentioned also, who honestly cares really what the idle temp is, only temp that matters is under load reative to how close you're at to throttling

i cant check for the ambient temp right now as I'm monitoring it remotely, but now it hits 40C idle which is very alarming for me, because I never seen such idle temp on my opty 185 oc'd at 2.8 before...

How are temps wrong by 8-10 degrees?

How is that possible? 22 to 23C is practically 73F maybe a little bit higher... I always seem at least a good 10C-15C higher idle temps over ambient temps.

My computer idles anywhere from 30C-45C depending on the ambient temps.

Yep - same for me except that the lowes it will go is about 38 with the 9700 @ stock!

I've been having a similar problem to this guy, I however, do not have as many case fans as he does, so in his case something must be up.

What cryptonomicon is referring to is what I noticed during extensive testing.

With my revision B2 E6400, CoreTemp 0.95 assumes a TjMax=85C and reports core temperatures from 48C to 85C exactly equal to what I read with an IR thermometer pointed directly at the core without a heatsink or fan getting in my way of getting an accurate reading.

That confirms that assuming TjMax=85C for my processor gives realistic load temperatures but when I reduce the cpu voltage and the MHz to minimal values, the same CoreTemp program that worked properly at higher temperatures will start reporting temperatures less than my ambient temperature which is impossible. The reported core temperature can also be 8C less than the copper heatsink block which is attached to the IHS which is also impossible. The heatsink can't be warmer than the item giving off the heat.

CoreTemp is reading the on chip digital thermal sensors ( DTS ) correctly as confirmed with CrystalCPUID which lets a user read these register directly. My conclusion was that the DTS is not 100% accurate at very low idle temperatures so shouldn't be trusted and that data shouldn't be compared with other users because it is meaningless.

A better test is to run Orthos at a fixed core voltage and a fixed MHz and then compare your reported temperatures. There's a lot more meaning in load temps compared to idle temps.

Coretemp if I remember correctly reads from the core diod as where other programs read from a diod under the chip on the motherboard. Coretemp does exactly what it says it does, give you a temperature at the core which is going to be a good few degrees warmer then say 10mm underneath the processor.

CoreTemp and SpeedFan are reading directly from the on cpu digital thermal sensors and report the same on my computer.

The only problem is trusting the DTS at low idle and low room temperatures like this.



With a room temperature of 20C you can't get an air cooled processor down to 16C. My Tuniq is working great and I'd like to think I'm pretty good at squirting some AS5 on top but that is simply impossible. It looks even worse when you consider that an IR thermometer reports the copper block at the base of the Tuniq at 26C.

If the DTS on my chip reports idle temperatures that are too low, it is also possible that on someone else's Core 2 Duo, their idle temperatures are being reported too high. If you can't come up with a reasonable explanation for the above then I wouldn't be trusting idle temperatures that are based on the DTS.

No wonder your temps are soo low... you've lowered your CPU power... i'm not sure if this is what you've meant to achieve but if not, it has probably been caused by messing around trying to overclock.. and the multiplier has been messed up, resulting in lowering your cpu power.
Your CPU is suppose to be clocked at 2.13GHz (8x multiplier) (Core2Duo E6400) and you have it 1203.7MHz (6x multiplier)...

To reset this, simply switch off you PSU from the mains.. wait 10 secs.. find and remove the battery from your motherboard.. wait 10-15 secs... "put the battery back" and connect you pc back up to the mains.. when you start, you motherboard and messed up overclocking will be back to factory default.

Thanks for the info CAMPER. I knew I must have screwed something up!

I have the same exact setup E6600 and Zalman 9700. My temps are on par with yours, I wouldn't be worried about it.

I thought I would just share this with you:

I've overclocked my CPU to 2.880Ghz with RAM @ 640 with 4-4-4-12 timings with the following temps: 36 @ idle and load ~45-47 " load according to Coretemp, not too bad IMO.
