Hi temps normal on i5 4690k? Using a Hyper 212 Evo - Page 3

post #21 of 26
The reason I posted that specific tweak town chart is because it's the newest one they posted today l, it just happened to be a different CRYORIG cooler they reviewed

I think your temps seem pretty normal. The 212 Evo is OK for a mild OC. I have the 212+ with a 4690K. At 4.5GHz and 1.23v it hits about 72C on Prime95 26.6 in a pretty warm 28C room.
Later versions after Prime95 26.6 will make Haswell run hot.

TweakTown, like most others has more flaws in their test procedure than good. This kind of testing is smoke and mirrors .. and has little bases on empirical data. Maybe they don't know how to do accurate testing, or maybe they don't care. It really doesn't make any difference. The end result is data that has little meaning.

First flashing red and blue lights are CPU temp reading "accurate" to 0.01c. doh.gif What is the accuracy of air temperature going into cooler? How accurate/consistant are cooler mounts and resulting TIM heat transfer? Next is H110 being 3c cooler than H100, and H100 being 3.25c cooler than H220-X, with NH-D15 being 6.58c warmer while NH-D14 3.17c warmer than D15, but only 1.17c warmer than R1 Ultimate.. R1 Ultimate and NH-D15 are +/-1c different in accurate testing. H100 is very close to to same as well, not 4.08c cooler. Of course the differences will vary depending on how much heat CPU (heat source) is producing, but these kinds of anomalies show how flawed the testing procedures of most reviews are.

Without accurate basics we have nothing .. only wasted time.
How is system calibrated before (and after) each testing session?
What is the base air temperature?
where is it monitored?. (only relevent temp is air going into cooler)
how often is it recorded? (should be same as CPU temp)
What is the barometric pressure and humidity during each test session? (any change effects air's ability to absorb heat)
How many times was cooler mounted to establish consistency? (+/-1c margin of error between mounting is not uncommon)

And that's only for starters.

Many have tested the same top coolers and we have found the NH-D15, H100, R1 Ultimate, etc to be very close to equal in cooling ability (+/-2c), but H100 & H110 are much louder (26dBA).

It is extremely easy to pick apart the attempts of others like I did here, but it is extremely hard to setup a test system that gives accurate results.

I have tried. wink.gif
Accuracy of +/-1c is about as good as it gets ..

Well I've settled on the following stats

Multiplier--44 (4.4GHz)
VID--1.260V
Max temp 73* but usually hanging out below 70.

I went with 4.4 because as I tested out the 4.5 and the jump in voltage and fan noise was significant. my 4.5 setup eventually needed 1.305V, and temps were getting up around 78, with the 212's fan maxed out and pretty loud.

The handbrake Realbench tool is great, but I didn't realize I was just benchmarking. Once I started doing the real 15 min stress test it got a lot hotter than before.

I can see what one of the people in this thread stated, having a fan run at such high % is very loud and i'd expect a faster demise of it.

Under load, my 4.4GZ setup is much quieter. I can switch my front case fans to low for normal use and i like being a bit quieter.

I'm not a super overclocker, but I really appreciate your guys' help. Next time I build, I'll definitely look into getting a better cooler, though to be honest I'm pretty happy with my set up. You guys are very helpful.

It has to be one of the best-designed coolers ever. It's still competitive, and still being sold and produced, after almost a decade.

The only thing about it doesn't ship with any fans (which isn't a problem), but Prolimatech prices it on the high end of its class along with coolers that do ship with fans. On the other hand, fit a couple of good 120mm fans to it in push-pull, and it performs 90 percent as well as a D14 without looking butt-ugly. thumb.gif

Hi everyone, I hope this isn't resurrecting a thread that's too old, but I wanted to ask a couple more follow up questions.

So I was a goofball and used a fan that I didn't realize was as good as the Hyper 212 Evo fan. So I replaced my cpu fan for more rpms and better CFM airflow.

I was able to resurrect my old 4.5GHz setting, and the final VID I had to use was 1.31V.

The VCORE fluctuates up to 1.332V in a RoG stresstest.

The max temps I was getting though were 75 or 76*C.

From what people have said, these temps are ok, but most sources warn to use liquid cooling after 1.32V VCORE.

Any thoughts? If I can keep the temps below 80 on a stresstest, is it no big deal, or should I avoid this new setting?
