Hot temperatures on my E6600

Hi all,

I'm currently (and have been for over a year) running my E6600 at 3GHz with a Thermalright Ultra 120, including a 12mm Zalman silent fan. My ambient room temperature is around 22c. Its in an Antec Titan Case running on an Asus P5W DH Deluxe.

The temperature on my E6600 when idle (and has been since installed) is ~60C (according to CoreTemp). The TJunction is 85C!

My CPU has always run hot (before the Ultra 120 I used an Arctic Cooling Freezer 7 Pro, but this couldn't keep the temperatures below 70C on Idle at 3GHz!).

Does anyone think I may have a duff heatsink? Or is this a pretty reasonable temperature to expect? It doesn't rise drastically when heavily used, but I've seen quotes of people using a Ultra 120 on an E6600 and getting 3.6GHz out of it with lower temperatures than mine? DO they live in the North Pole or am I just unlucky?

Any help appreciated!

(For the record I'm using the Thermalright paste that came with the Heatsink, which can be improved upon I know)
 
Thats very hot, what's it like on load?

Assuming you have mounted it right (on both occasions) what v-core are you putting through it?
 
Thats the strange thing, it doesn't seem to go much above 66 when under-load for an hour.

CPU - E6600
Core Speed - 3001GHz
Voltage - 1.368
Multiplier - x9
Bus - 333.5
RAM:FSB - 1:1

I'm convinced its mounted correctly, it was a careful job. I'm getting a new GFX card and RAM before this weekend so was considering buying some new thermal paste and seeing if a re-mount will help. Wanted to get some "experienced" opinions before I did this.

The main reason is I'm trying to get a bit more out of my computer without having to upgrade. Buying more RAM and a new GFX card has been the cash bit, I'm hoping to up the CPU speed for free :)
 
That seems really hot mate. I'm running the same cpu at 3.2ghz and while I type this according to Core Temp I'm 27c. I'm using the Noctua with a 9 blade Noctua fan and Artic Silver. I don't live in the North Pole and where I am it's prolly a bit warmer than back home right now.

Current settings are 400x8 with 1.35v.

It might be worth getting some Artic Silver paste but shaving off like 30c seems a bit of a mission.
 
Sounds like stuck sensors to me if the temperature at load does not go much above idle. However I only remember hearing sensor problems on the 45nm wolfdale chips.

Thanks for the details PERS, I'll try a re-mount with arctic silver and see how it goes. May try upping the fan speed on my 12cm fan thats attached to it as well.

I'll try and lower my voltage, (and match your multiplier x fsb it). This should allow me to get my RAM in 1:1 at 400, rather than the 333 its running at now :).
 
Fixed, it was me being a noob....

I bought a new PSU after my old one gave up the ghost some time last year. However, once I installed the new PSU, I left the Vcore in the BIOS the same as previously.

With my new power supply being much more efficient, it was supplying more voltage under load to the CPU. I've managed to lower the voltage under load from the above 1.368 to 1.336 (according to CPZ). Correspondingly, the temperatures now idle at around 50 (still too high, but better), and peak around 58. Looks like it wasn't stuck sensors though!

In the BIOS it was previously set at a supplied voltage of 1.4 (HOW HIGH?!?!) previously and is now set at a measly 1.35.

Sadly, I can't get my PC to boot on your multiplyer/FSB settings, even with a supplied voltage of 1.425! I'll get the arctic silver and see how that performs. Thanks for help guys.
 
have you tried other temp reading programs? i have core temp,speedfan,everest just to cross reference with. they temps are way to hot at idle!!
 
Ok then, based on that last comment it is quite clear i have a cr@p CPU...

The Thermalright Ultra 120 is one of the best air cooled heatsinks you can (could?) buy. It now has freshly applied Arctic Silver 5 linking it to my E6600 (applied according to the official site's instructions).

The 12cm Akasa Amber that I have attached to the heatsink (a highly rated 12cm fan) blows straight through the, now cleaned, heatsink and is also blowing onto a 12cm Antec case fan that is sucking air straight out the back.

The two 92mm Xilence Redwings in the front of my case are sucking enough air in so as not to produce a "vacuum" effect inside the case.

The HX620w Corsair PSU has a further 12cm fan pulling air over the CPU heatsink.

With all this placed inside the spacious Antec Titan I see no logical reason why airflow should be an issue.

Yet, with all this, I can get my E6600 stable at "only" 3GHz, with a VCore of 1.3625 (It managed only 10minutes on an Orthos Blend with a VCore 1.35 before getting a rounding error).

And with these settings, it runs under load at temperatures of 60-62.

There is no way I could reach 3.2 with a voltage of less than 1.4. And with this voltage its quite clear my temperatures would be hitting the mid 60's under load, and mid-50's when idle.

I can live with these settings, 3GHz is still fast enough for what I need to do, but it aggrieves me that there can be such a variance in performance of the same CPUs. Its also tyipcal that I got lumbered with one of a bad batch.

If anyone see's anything untoward in the above it would be good to hear your thoughts. Thanks people.
 
I think its sensors or the mobo itself, id be surprised if the cpu was at that temp. If you can try the chip in another mobo do that. How hot is the HS to touch near base - you'll know instantly then if it really is at 60c.

which mobo you are using also - there are some gaps that might explain it rather than just the cpu/heatsink.
 
I'm using the P5W DH Deluxe.

I've felt the heat sink as close to the base as i can....there's not a great deal of room for maneuvre, but I would say it is merely "warm", rather than "hot". It certainly didn't hurt my finger to touch, so perhaps the sensors are out.

It does seem completely illogical to be running at the temperatures it is at though. :confused:

What would be the life expectancy of a E6600 running at 60degrees nearly 24/7. If its less than two years then I think we can safely say it is the sensors, as my CPU is still very much alive after such a time frame ;).

I imagine 3 or 4 years :P

Considered lapping the heatsink?
 
Hey all, I've got a similar setup (E6600 & P5W DH Deluxe) with a Arctic Freezer Pro. I was just wondering which temp do you get your readings from in Speed fan? CPU or Core temps?
Also, does anyone know what temp the AUX field is recording?
Thanks
 
I use CoreTemp and Intel's Thermal Analysis Tool. They both give the same readings, although TAT allows temperatures to be logged.

I find speedfan gives highly inaccaurate temperature readings (sometimes 10degrees below what it should be).

I have considered lapping the heat sink, but don't have the will power/time/patience/ etc. I'll just keep up with it as it is and replace the CPU when it finally dies. Not to worry, thanks everyone!!
