Looking to test the limits of my Core i-7 940 2.93ghz processor. I have it currently overclocked at 3.42ghz. When gaming for hours it will reach 48c. What is considered too hot so I know where the limit is. Here are my specs, thanks.
Although Intel still doesn't show a value for Thermal Specification in their Processor Spec Finder - http://processorfinder.intel.com/details.aspx?sSpec=SLB... - for any of the three Core i7 variants (920, 940, 965), the most informed opinions are that i7's share the same Thermal Specification as the new "S" series Core 2 Quads, such as the Q9550S.
-Tcase/Tjunction- --75--/--80--80--80--80-- Hot --70--/--75--75--75--75-- Warm --65--/--70--70--70--70-- Safe --25--/--30--30--30--30-- Cool
Tcase = CPU Temperature Tjunction = Core Temperature
During the coming weeks, I will be updating the Guide, which will become the "Core i7 and Core 2 Temperature Guide", and will include the latest information for Core i7 temperatures. For the present, since Core i7 and Core 2 Quad CPU and Core temperatures function identically, if you'd like to learn how temperatures work, and how to test, calibrate and monitor CPU and Core temperatures, then check out the Guide.
I have a similar question on the amd side. I have looked at the specs for the AMD x4 940 which I have been happily overclocking with some good results. However I am very concerned about thermals.
Here is the page I will refer to, which is located on AMD's website.
"February 2009 AMD Family 10h Desktop Processor
Power and Thermal Data Sheet".
From the looks of this page, it appears the thermal specification for my Phenom II is 52-60 C for max ambient temperature, while the max core temp appears to be 70C.
If anyone can verify this for me it would be greatly appreciated.
So far I have been able to OC the processor to 3.8 GHZ. I am using a Biostar 790GX A2+ mobo and a Cool-it Domino ACS cooling system. This is also my first foray into water cooling.
When I reach 3.5 ghz, I need to apply 1.3750 v to achieve stability. This results in my processor idling core @ 41C. Maxing all cores I have a load temp of 51C which is what I was comncerned about. Ambient only goes as high as 36C.
At 3.8 Ghz, I am applying 1.45V for stability, and it is solid. Not much change in temp, 42-43C idle and maxed out I get 53C. Which was scaring me. Ambient temp at no time has climbed above 40C.
I was hoping to run 24/7 at 3.8, but as I mentioned the thermals seem high. I should note that all this is done at medium speed setting on the domino, it cools extremely well on high but easily drowns out the video card, or even nearby conversation. However I will put it on high when I head north of 3.8 ghz.
