OCCT Give a msg "CPU too hot" at 75C.

post #1 of 13
Thread Starter 
Hey !

I'm running OCCT and after 10 min getting a msg "CPU too hot" and the test stops.
(not getting any blue screen)

the current setup pass 20 loops with LinX already, max temp was 75C.

i checked Intel's site: http://ark.intel.com/Product.aspx?id...&wapkw=(i7+950)

and it says: TCASE 67.9°C

should i not pass the 67-68C ?

im currently running on 1.2v 3.8ghz

As long as you're around 70-78ºC don't worry, but don't let it go above that.

The Tcase sensor is under the heat spreader but above the cores, for the i7 9xx series it seems to read 5-10C less than the core temps, or thereabouts. So given that is Intels guide Tcase value the accepted wisdom is that you can 'safely' go into the 70s on the core temperatures. Some people are happy to push things further though, and of course some people are more conservative.

Ok, so is there a way to make iy keep running?
Temp not going above 75 anyway.

Thanks guys.

Incorrect, TCase is the temperature at the top of the center of the IHS. The only way to measure it would be to put a probe between the IHS an the whatever you are using as a cooling solution. There is no sensor for TCase.

Also the CPU reports the distance from Tjunction not necesarily the temperature that it is at. Intel probes are more accurate at or near the Tjunction and any "temperature" reading is merely extrapolated.

These chip run hot. Hotter than i expected. 100c is thermal limit, or at least when the chip will begin to protect itself. Not that you want to get there, but I don't think many worry about temps in 80's when stress testing with something that will raise your temps to levels you will never see in real world usage. Especially ibt in very high or max. Now mid 90"s? Well, I think most will avoid any long term stress tests with temps in that range, but many have gotten there.,

Nope, there is a sensor there. You are nearly right, the sensor is at the top of the center of the IHS, only it's just under the heat spreader not some notional value above it as you suggest. There are many programs that will allow you to read the temperature of the Tcase sensor. The Asus AI suite displays the value of that sensor for one. Everest will display it also.

Your final paragraph is correct.

I've hit 95*c running Prime95 on the stock Intel heatsink right before I threw my NH-D14 on.

After D14 AND overclocked to 4ghz it only hits 65*c.

I would definately raise the temperature warning. 75*c is nothing for a Nehalem chip.

Also remember that loads presented in OCCT and Intel Burn Test are completely unrealistic of what your computer is to encounter unless of course you are folding on your CPU while playing a game. Then you might encounter OCCT like loads.
