I've just overclocked my i7-6700k CPU and wanted to get anyones opinion on whether these temps are too much.

I've managed straight out on first attempt to get a stable (currently) 4.74GHz clock.

This is with a Coolermaster Hyper 212x cooler and a Vcore of 1.35v

Prime95 testing got it sitting at around 80c at this clock rate, with it dropping down to 25c with minimal loading.

Are these temperatures OK?

If your core temperature at idle is 25C, assuming it's accurate, then your ambient temperature has to be at least 23C.

Regardless, 80C load temperature is excellent for your ambient, Vcore, overclock and cooler, especially when running P95 v28.7.

However, your temperatures will test considerably lower if you use P95 v26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html

Run Small FFT's for just 10 minutes.

Use RealTemp to measure your core temperatures, as it was developed specifically for Intel Processors - http://www.techpowerup.com/downloads/2089/real-temp-3-70

Version 287

Ambient is mid 20's right now, but can go up to 30+ (Australia with no air con)

Using CPUID HW Monitor to view temps, etc.

Thanks I'll take a look.

I ran Prime95 v287 again for 20 mins or so, using RealTemp - CPU never went over 81c

Mattb81,

Unlikely as it may appear, your 6700K is "Throttling".

6th Generation processors have 2 new features which can invoke throttling at 80C. This is described in the following Datasheet: 6th Generation Intel® Core™ Processor Family Datasheet, Volume 1 of 2 - http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/desktop-6th-gen-core-family-datasheet-vol-1.pdf

(1) See Section 5.1.4 - Configurable TDP (cTDP). Allows Thermal Design Power (TDP) to be configured "Up" or "Down" in BIOS.

(2) See Section 5.1.7 - Scenario Design Power (SDP). If "cTDP Down" is in "Auto" or "Enabled" in BIOS, then Thermal Control Circuit (TCC) activation is 80C.

These new features are designed to keep Core temperatures from exceeding 80C, when loads such as Prime95 v28.7 or heavy transcoding, both of which use AVX code, force the processor to continually operate near TjMax (100C).

You might want to look in BIOS to see if cTDP and SDP are in Auto or Enabled by default.

Surely then the frequency would reduce? But it's still at full. My earlier post is to be ignored, I wasn't OCing correctly via multipliers. Since corrected it.
