Hey guys! I just builded up my new rig and already have some questions about my CPU temperature.

Idle: 25-31°
Prime95 (after 15 Minutes): 53-56°
Prime95 (after

I changed the H105 from push to pull, do you think I can leave it?

Whats the critical temparature?

Core Temp is showing a power usage of 30-70 watts in IDLE mode, isn't it a litte bit strange?

That's my first own build and it was really expensive. I am a newbie in hardware modifications etc., thats why im asking you guys.

Maybe there are a few mistakes in my language, im sorry.

Greetings from Germany!

Welcome to Tom's!

At the top of each Forum you will see "Stickies", which are special information threads that are permanently posted to answer questions, and are there for everyone's benefit.

If you look at the CPU's Forum or the Overclocking Forum you will see this one:

Core temperatures in the mid-70's are safe.

paschmuk,

Welcome to Tom's!

What is your ambient temperature?

Core temperatures in the mid-70's are safe.

Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. Core temperature is 5C higher than CPU temperature due to the differences in sensor type, location and calibration. Tcase for your 6 Core 130 Watt i7 4930K is 67C: http://ark.intel.com/products/77780/Intel-Core-i7-4930K-Processor-12M-Cache-up-to-3_90-GHz

Tcase + 5 makes the corresponding Core temperature 72C.

Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor. Heat originates within the Cores where Digital sensors measure Core temperatures. A single Analog sensor under the Cores measures overall CPU temperature.

The relationship between Core temperature and CPU temperature is not in the Thermal Specifications; it's only found in a few engineering documents. In order to get a clear perspective of processor temperatures, it's important to understand the terminology and specifications, so please click on the link to the Temp Guide and get yourself up to speed on this topic.

Here's the normal operating range for Core temperature:

80C Hot (100% Load)
75C Warm
70C Warm (Heavy Load)
60C Norm
50C Norm (Medium Load)
40C Norm
30C Cool (Idle)

Your highest temperatures will occur when running test utilities. Temperatures are typically lower during real-world everyday workloads such as processor intensive applications or gaming.
