have stock cooler on i7-940 temp program shows @55 c is temp ok would like it cooler

More about : warm 940 cpu

At idle or at 100% CPU utilization? If at 100% CPU utilization, then it's fine.

57°C is way below the maximum.

Prolimatech Megahelems or Mega Shadow. Best air cooler on the market today.

It depends, on Idle, i'd say its bit to high but if its performing a processor intensive task then its fine. However max temps are way above that so i wouldn't worry.

If that were true then I overheat my i7 920 by about 15C doing anything intensive :lol:  Luckily it's actually around 100C (usually).

Oh Damn really? Do you have any evidence?

If thats the case, what am i doing at only 4ghz. Bring on 4.2 :D  :D

Intel specs sheet. That 67'C is for the cpu outer shell/case I believe...the cores can take 100'C before massive degradation/failing.



It's $10 cheaper on Amazon.com =)

Yep the recommenced temp is 70c but the true max is around 100c.

Well in that case I better stick at 4ghz, my temps under OCCT are 69/68/68/66, so pretty close to the recommened limit.

I probably wouldn't see much performance gain out of an additional 200mhz anyway.



***Sigh!*** :(  :(  :(

Your probably right.

What recommended limit are you talking about? Intel never specifically specified any other limits with regards to the cores. If I was to keep my i7 920 under 70C I'd have to stop using it for what it's most useful for... rendering.

Where you meaning to the Core brands or the individual cores in a cpu? For the brand they do have recommend temps but there just recommendations.

http://processorfinder.intel.com/details.aspx?sSpec=SLB...

Look under "Thermal Specification"

Thermal specification refers to the maximum temperature that should be reached at the geometric centre on the topside of the Integreated Heatspreader. With the exception of mobile CPUs, it has no direct relation to core temperatures. For Mobile CPUs (which have no heatspreader) it refers to the maximum core temperature before throttling occurs, and usually it will be a more round number such as 105C.

If it was just a recommendation, it would not be so precise :)

So randomizer what is your core i7 running at? and at what temps? (just curious) : )

It's summer, so room temp is in the high 20s (celcius) much of the time. I idle at 47-50C and load at around 65C. I run stock speed but I undervolted by 0.16V. At stock vcore I idle about the same but load at around 82-84C.

Your CPU runs very hot for an undervolted one?

I get ~29C on Idle and ~40C on max load

Well, I'm using the stock cooler in high ambient temperatures. You can't expect much. It's even more interesting when my room temp exceeds 30C/86F.

Get an after market cooler and OC that beast! :D
