Yes, I've noticed that the Turbo mode is still on, even if it is not an option in the BIOS.

Two key points, high temps are bad and you should think about getting an after market CPU cooler.
The Intel cooler is very limited. You can get a good air cooler for $20-50.

Make sure your case gets proper air ventilation, don't put it in a small closed cabinet.

CPU thermal paste is very important to get applied correctly, read up on it, there are a lot of info on how to do it. Too little doesn't work, too much doesn't work either, just remember you are filling micro holes on the metal finish so it needs to be very thin, almost transparent. Ensure the cooler mounting bolts are tight.

I have Noctua NH14 CPU cooler with ArticSilver 5 applied, as per instruction at ArticSilver site. You did summarize the process well, better than the site did.

I don't use the cooler that comes with the CPU, it's more of a noise reduction purpose than anything else. The tower also have four case fans; two on the front pulling in air, while the back ones are pushing air out. There's one internal fan for the four hard drive and of course the standard CPU, power supply, and video card fan(s). It's still quite since the fans run at 900-1200 RPM.

Check your CPU specs here.

Thanks for the specs...

The RealTemp 3.6 indicates TJmax as 99 degree Celsius; evidently, that's an incorrect value then, right?

Here are some of the temperatures, using Real Temp.

Default settings in the BIOS, no OC:

I am not sure that the temperature for the torture test is normal. Other than that, the system runs just fined OC-d to 3.2.

The temperature difference from the idle to the torture is about 40; is that a "normal" swing? Once the torture is over, the temperature quickly drops down to the idle values.

The RealTemp TJmax of 99°C is wrong for your CPU, it's the default value RealTemp uses. Each CPU has a different max temp safe limit, RealTemp doesn't change automatically.

Mine idles at 29°C and with Prime95 torture test at 57°C.
My OC goes to 3.84 on 1&2 cores and 3.36 on 3&4 cores.

I would put the fan on your CPU cooler, it will cool much better when your CPU is running fast. You should have about 30°C increase when running Prime95.
The fan should drop your temps by 10°C when the CPU is running at max speed.

Dave, are you sure? I've done a lot of reading on this, and while I've yet to see an Intel page saying X is the TJmax, it is widely said that both the i5 750 and i5 760 have a TJmax of approx. 100c. It is said that the creators of Real Temp have done extensive testing with DTS on the case and the actual die. I am led to believe that this is the actual TJmax for these CPUs. While it is a relative moot point if your max temps don't exceed say 70c. Any clarification would be great. A Guy

That's a "cool" machine you've got there...

Mine does idle about the same value with open case, but during the torture it goes up to the mid-seventies:

Closing it up and placing the case back into my desk increases both values by 6-8 degree Celsius.

I do have a fan on the heatsink that is also right next to the case fan in the back and top of the case. I used Zalman heatsink in the same case for my Core2 CPU and I could disconnect the CPU fan, close the case, and the CPU temperature didn't change much. That's how well the two case fans moved the air around the CPU.

The Noctua heatsink did come with two fans, 120 and 140mm, and I am only using 140mm one due to space restriction and keeping the machine quite as well. Maybe I should reset the heatsink, figure out a way for adding the second fan, or should have stayed with Zalman.

Intel® Core™ i5-750 Processor (8M Cache, 2.66 GHz)

Tcase is the CPU, add 5°C for the core temps.

72.7 °C + 5°C=77.7°C is the max safe temp recommended by Intel.


This thread explains it pretty well.

What Is The Maximum Temperature Stock Fan Core i7 920???

Scroll down to

CompuTronix's post.

Core i and Core 2 processors have 2 different types of temperature sensors; a CPU case (not computer case) Thermal Diode centered under the Cores, and Digital Thermal Sensors located on each Core. The case Thermal Diode measures Tcase(Temperature case), which is CPU temperature, and the Digital Thermal Sensors measure Tjunction (Temperaturejunction), which is Core temperature. Since these sensors measure 2 distinct thermal levels, there is a 5c temperature difference between them, which is Tcase to Tjunction Gradient. Core i7’s / i5’s and Core 2 Quad’s have 1 Tcase and 4Tjunction sensors, while Core 2 Duo's have 1 Tcase and 2 Tjunction sensors ...

The Thermal Specification shown in Intel's Processor Spec Finder is Tcase Max (CPU) not Tjunction (Core), which is a very common misconception among most enthusiasts. Since there's a 5c gradient between the CPU sensor and the Core sensors, (shown in the following Intel document) - http://arxiv.org/ftp/arxiv/papers/0709/0709.1861.pdf - just add 5c to the value shown in the Spec Finder to determine the corresponding Core temperature, which is 73c for all Core i7 9xx variants.

Intel's second and frequently misunderstood Thermal Specification, Tjunction Max, (100c for all Core i7 9xx variants) applies to overtemp protection such as Throttle and Shutdown, so you don't toast your transistors. As such, any i7 9xx Core temperatures which exceed 73c should be considered "overtemp". Further, when specifications are exceeded, then processor degradation becomes a concern, which is explained in the following AnandTech article -http://anandtech.com/cpuchipsets/i [...] i=3251&p=6

To clarify my post above, most people think TJmax is the max temp they can run there system at, it's actually the over temp protection functions that keeps you from melting your CPU. To make shorter explainations I usually assume they mean max temp they should run there system at.
