Intel i7 4790k Devils Canyon Temps

[BradleyJames]

Im starting a thread to hopefully relieve some stress and concerns regarding the high temperatures on the new intel i7 4790k devils canyon cpus.

First off, they do run very hot when using the included intel thermal solution. In my opinion, intel kind of dropped the ball when it came to cooling this mini arc reactor of a cpu. it doesnt matter if you have good airflow in your case or change the thermal paste. it is insufficient. I have a corsair 760t with great air flow and i changed out the thermal paste for MX-4. i even tried to add another fan in the top of the case blowing directly on the cpu, didnt make much of a difference.

When running IntelBurn test, which i like to use for quick, max stress, with the stock cooler, temps would instantly sky rocket to 92 celcius and the cpu would throttle to avoid overheating. I perfer OCCT when overclocking because it is a little more realistic load on the cpu for day to day use. OCCT would still get high 80's after an hour. Also, i noticed that having Asus Multi core enhancement would run all the cores at 4.4, instead of stock , which is a few cores running slower.

I would recommended getting an after market cooler for this cpu. If you are like me, you cringe at the site of your expensive cpu hitting those temps. I would recommend getting aftermarket cooling. If you dont plan on overclocking, the Cooler Master Hyper 212 evo should be fine. I recently read in a magazine that if you are going to spend more than $40 on cpu cooling, your best bet is to go with an All In One ( AIO) closed loop liquid cooling.

So, after some research, i decided to give the Cooler Master Nepton 280L Extreme liquid cooler a try. After Installing, using my personal favorite Arctic Siver AS-5 thermal paste, My temps dropped significantly, to Mid to high 50 celcius. i ran at stock speeds for a few weeks, as AS-5 take about 200 hours to cure.

Now to the overclocking. Currently, i am running a 4.7 ghz overclock at 1.258 volts. I have an asus ROG maximus vii z97. My temps Stay around 60 celcuis , Max 72 when running OCCT for an hour and 80 max on intelburn test. once again, Intelburn creates an un-realistic load on the cpu, and i have never hit anything close to that gaming, thats why i like OCCT. With my 2 way sli gtx 780tis, it stays around 50 celcius and the fans dont even have to be running fast on the nepton cooler.

please reply with any other questions, concerns or comments and i will be happy to help shed some light.

I seriously doubt that cooler gave you a forty degree difference in the load temp. It's more likely the stock cooler either came with too much TIM, which they do to make sure the average user doesn't fail to propertly mount and bond the heatsink, or you put too much TIM or had a bad mount with the stock cooler. I've installed several DC cpus with the stock cooler and never had a 90 temp while load testing. I've heard of others who have though, but it's likely they overloaded the TIM as well. Or didn't put enough. A rice sized amount is plenty.

Edit: I'm talking stock clocks though. If those temps were at a 4.7 OC, you're probably just looking at the simple fact, as we all know, that stock coolers suck.

Thanks but I know what im doing, ive done close to 100 builds and I know how to apply paste. This is sharing my experience ao others know theyre not alone. Whats wo ha4d to believe that a 280 mm liquid cooler will take 40 degrees off? This is the third I have used, an antec and an h100i on a 3770k and this is by far the best. Id apperciate u keeping what u think u know to urself as not to deter others. Thanks

If you don't want other people offering their opinions, whether they are in contrast to yours or not, don't post on a PUBLIC forum. Or write it as a tutorial and select the option to not allow comments. And I didn't say anything about you knowing what you're doing. I'm sure you do.

That being said, I still find it leaning towards the hard to believe category, especially after verifying my suspicions through several (5) various testing sites that used i7 processors and the Nepton 280L. Upper range temps at full load with stock clocks were only 1 degree different than with the Noctua NH-D14. Overclocked temps @4.2Ghz with the Nepton were also only a 1 degree difference at full load. And the noctua doesn't provide a 40 degree difference over the stock cooler at full load, that's a fact. Results were similar across testing sites with the only real benefit indicated was the smaller footprint of the water block compared to a large heatsink. That makes it AWFULLY hard to swallow a 40 degree difference. You see, I know what I'm doing too, and have been doing it since about 1984. I also know when something smells funny, and this does.

I won't say you're being blatantly untruthful, because I don't know the rest of your rig, or what kind of configuration you have going. Maybe you have a set of the fracking Corsair high performance fans on there running at about two grand. In which case, yeah, maybe you're right. But I'd sure have to see the evidence myself to believe it. Anyhow, when testing facilities that do this for a living get a one degree difference from an air cooled fan, and they are both still hitting 80c at a full load with an i7, THAT is what makes it so hard to accept. And if you ARE correct, you shouldn't be worried about what I think anyhow.

You are right I shouldnt get upset about others opinions in a public forum. I was just a little dissapointed that my first comment was doubt I stead of a thank you when all im trying to do is thank people. I will post some screen shots when I get a chance of my overclock temps when I get a chance. And my fans are cranked right up to high when im stress testing

 

[BradleyJames]

In the next few weeks im gonna grab an nzxt kraken x61 and do a comparison of it vs the nepton

 

[Darkbreeze]

Sounds like a plan. I'm interested to see the compared results on your rig. It's always hard to say what truly compares to our own hardware since every rig is so different, even though they're seemingly similar when you look at the parts on paper.

Just browsing this thread with no other software running and a x61 kraken, Im sitting at 27 deg C. I replaced stock thermal paste before install.
No over clock just stock 4 ghz. this is a new build and my other box crapped out, but will post some temps running games if it helps... but damn Im loving the Kraken. Case is also NZXT h440.

The cam software tells me this .....
Fan speed set at 70% ...... fan rpm 1500 - 1560 ...... pump rpm 3240 - 3360
Liquid temp sitting at a solid 28 deg C

Noise levels? With those RPMs I'd think it would drive you nutty.
