Q6600 confusion with temperatures

[silvercue]

Hi all,

As you can see it's my first post. I found the forum serching for help on my Q6600, I stumbled accross a great article by a member here called graysky and thought collectively you might be able to help me out.

I built a new rig (in siggy) last week and was happy to see it boot to Vista64 fine and I ran a few applications without a hitch.

Then I ran some checks on temp as I plan to make sure all is stable then overclock.

The system is 50-55 Idle according to Everest and uGuru and the Individual Cores are between 30 and 40 using Core Temp (TjMax 100).

Temps seem too high to me.....and I had lock ups running Orthos stress test, within 3minutes.

I assumed that was due to the temperature which shout up to 68. But now I have uninstalled AVAST Anti Virus and do not use uGuru (motherboard software) and orthos does not cause lcokups.

However, I am still very confused about temperatures as I now also run REAL Temp which shows all the cores at 5 degress lower than CORE TEMP and it uses TjMax of 95.

I also have SPEEDFAN which shows the CPU temp as 10 degress lower than EVEREST and uGuru but shows the cores the same as CORE TEMP....and it also shows the SYSTEM temp as 10 degress higher than uGuru. It actually shows system temp as higher than cpu temp!

I really do not know what to trust as they are all showiung different combinations of temperatures. I am also not sure what are safe values as I have read many conflicting reports.

I have changed the RAM volatage to what it should be (2.1).

I beleive the high temps could be because I used TOO MUCH Arctic Silver 5, so I removed the HSF and wiped excess away with card, but temps are the same.

I have now got some Isopropyl Alcohol to do this more effectively when I get a chance and reapply the right amount of AS5.

I have also, temporarily, Overclocked to 3g via FSB and adjusted RAM speed so it does not go to fast to see what happened to temps and they are all up a bit, not drastically. Running Orthos the CPU is over 70 though according to Everest (so over 60 in SpeedFAn) and I turn it off as I dont think I hsould leave it running at that heat for too long.

I have also had blue screens when using SPEEDFAN. Along with the lock-ups with uGuru I am a little suspiscios as to why applications that monitor temperatures and can change fan speeds casue this. I have not changed voltages using them or overclcoked using them.

Would greatly appreciate any help.

PS - the fan blows air downwards - towards my GPU - it can be set to go up, but that leave little room between HSF and PSU....not sure what would be better. CPU fan is 12cm and only seems to spin at 1380, I cant seem to get it higher. Box says it has max of 1500.

Case has decent flow and a few fans. System temp is normal.

Sorry for the long post, especially for a first....I hope that I can be of some use around here!

Idle temps are not important. As long as the full load core temps for a quad stay bellow 75C it should be fine.
Core temp and everest give me the same temps and 100 tjunction is what it should be for q6600. I ignore the cpu (supposedly tcase, but its wrong) temp in everest and only look at the cores.

Whats your default cpu voltage (VID) and what voltage did u have it set while running at 3ghz?

Thanks for the reply Dark Cupcake.

The CPU voltage is 1.335. I was contemplating raisng the voltage to 1.36 for the overclock, but was concerned it would increase temps too much, so I decided to see how it ran without the increase...so I left it the same and it *seems* fine, although I have been away on business and had little time to use the computer. (hence my delay in responding).

I have even tried lowering it to 1.325 to see if that helped with temps, but it caused some instability (had 2 BSODs).

So as long as the COREs are not looking crazy, heat wise, I can ignore CPU temp?

EDIT: I just checked the setting VID in CORE TEMP and it shows as 1.325....it shows as 1.335 in BIOS though.

stock intel hsf??? Entirely undersized if so... at least imo. Ive heard about the same temps from others with that setup. Im basically half of yours with the E6600 and at half the temps... with the TRUE120 and fan.

The core temps are whats important, as long as they are not hitting above 75C its fine. I'm not sure where everest takes the cpu temp (not the core temps) from, but for example my second comp shows that temp below ambient which is clearly wrong.

A friend of mine just got a q6600 (same VID as yours) on a gigabyte EP35-ds3p mainboard, and it took a voltage of 1.375 to fully make it stable it at 3ghz. He's still using a stock cooler but will be getting a new one cause the max core temps during testing were at 85C.

Fully load up all the cores, new version of prime 95 is good for that, see if its stable. If its not raise the voltage up a notch, you shouldn't need to go above 1.375, and do not go above 1.40. Just make sure it doesn't overheat. New heatsink would also help, something like thermaltake big typhoon would work fine at 3ghz if you are using a stock one.

Thanks again.

I am not using stock - I am using this:

Xigmatek HDT-S1283 Fan

Reviewed Here

The fan was recommended by the UK Store I got the parts from for overclocking this combination of mothernoard, RAM, CPU.

It is enourmous!

I will try Prime out.

I have now taken the HSF off and cleaned all the AS5 off with isopropyl alcohol and lint free cloth, then a blast of air.

The applied AS5 exactly per instructions.

Replace all and temps are same idle and seem a little lower at load. 2 cores still 10 degress hotter than other two though.

Can run prime blend test and cores and seems ok.

If I run small FFTs though system restarts itself after a couple of minutes, though temps look fine.

Thanks for all the help here, I will have to keep plugging away. Will look at cpu voltage now, may turn up a notch.

possibly a concave or convex IHS on chip? have you checked the heat spreader on the chip to make sure it is flat and have you checked tightness or snugness of fit while on the PC. Pretty big heatsink. If your using push pins for mounting Id recommend finding a back plate for it. I believe thermalright has one avalible. Yes they do here
