Temperatures Way Too High for Idle?

[DanteChiesa]

Hello, I built my computer around a year ago, and haven't had too many problems since, however recently my computer has felt like its really gone down hill, not only in performance for games (Major Fps drops), but in general use. I decided to look inside, cleaned out most of the dust, and the temperatures are still higher then I expected.

This was the build Im currently using, and these are the temperature readings when idle.

Im asking what should I check and if there is anything I can do to fix it.
Thanks!

when last did you open the case, took it outside and used compressed (canned) air to glow the dust out of the cooling components?

So all your temps are below 40c when idle?

There's no such thing as "too high at idle." Just stay below the Tcase most of the time, and you're fine. The Tcase for your i7-4570k is 67.4 C. http://ark.intel.com/products/65520/Intel-Core-i5-3570K-Processor-6M-Cache-up-to-3_80-GHz

So just make sure you don't go too high above that for too long, and you'll be fine.

DanteChiesa,

Welcome to Tom's!

At the top of each Forum you will see "Stickies", which are permanent special information threads. In the "CPU's" Forum and "Overclocking" Forum you will see this one:

Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

There is a proper way to test your Core temperatures at steady-state 100% workload and at dead idle. Please give it a read to get yourself up to speed on this topic.

Idle temperatures are of minor importance. Load temperatures are critical.

What is your ambient temperature?

Are you using Intel's stock cooler?

Guys,

"TjMax" is the "Core" temperature at which the processor will "Throttle" for thermal protection. The spec for the i5 3570K is 105C.

Although "Tcase" for the i5 3570K is 67C, this 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 + 5 makes the corresponding Core temperature 72C. <-- This is the spec, but we know that mid 70's are safe.

Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor, so a Quad Core has five sensors. 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 read the Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Thanks,

CT

Here's everything you need to know about your generation of i5: http://www.intel.com/content/www/us/en/processors/core/4th-gen-core-family-desktop-tmsdg.html

It's very technical. But the takeaway is that you just need to keep the load temperature below the throttling point, which is 105. Stay as close to Tcase as possible under load just to be conservative, and don't pay too much attention to your idle temperatures when asking whether the chip's too hot. Your CPU won't let it self burn up unless you tweak the BIOS and force it to do that. Don't force it to do that. With that in mind, jump into as much technical detail as you want as long as you don't forget the basics.

... you just need to keep the load temperature below the throttling point, which is 105.

Just to be unmistakably clear for Tom's members and our ever-present silent readers in the background, Core temperatures in the 90's or 80's are too hot for sustained operation. The CPU tests in OCCT will terminate at 85C for precisely this reason.

I prefer to say it this way; just keep it under 80.

just keep it under 80.

Eggz,

Nice rig!

Thanks, CompuTronix. I love it!
