Anyone got 4790k and Maximus Hero VII

I have have these two and would like to know did anyone have to disable anything in the BIOS to overclock. I am getting seriously high temps around 85-90+oC without overclocking so i would like to know thnx. I am using H100i and have resitted the cooler a billion times and there is nothing wrong with pump or anything.

That sounds really strange. Is everything at stock. How are you measuring temps? What thermal paste are you using?

Need ALOT more information, what your volts and so on.

What mark a you going after and do you take it by step by step ?
Will also like some picture, so we better can help you

Ive used three thermal pastes (coollaboratory liquid pro, as5 and mx4) and ive reapplied them each twice. I have coretemp, realtemp and HWMonitor.

Ive stressted using handbrake which is my video transcoder i use for youtube videos and got these temps.

While stress testing with OCCT i get 90oC+ for the first three cores and 80oC for core 4.

Yes I have a 4790k and VII Hero, and mine idles at around 28°c and under load hits 65°c thats at 4.4GHz, at 4.8GHz, it idles at 32°c and under load it hits around 95°c and that is about 1.35Volts.

So the information needed would be,

1. what speed is the CPU running at? eg 4.4GHz Turbo speed

2. What Voltage have you got for any overclock or just Turbo speed? (use CPU-z when you are getting the abnormal temps to get all the info needed)

3. Have you made any changes yourself in the bios or have you left it running at default settings?

4. Are you getting these abnormal temps while running anything in particular, is it random occurrence, all the time, or when something specific is done?

5. You say you have re-seated the CPU several times, have you damaged / bent any pins in the socket?

6. Is it just your CPU running hot, or is your Graphics Card, memory and or power supply also doing same?

I can't think of anything else to add to list of questions rattling around in my head at moment, but if you could answer some if not all of these, it will help narrow down things as to why and how things aren't right for you.

This is just out of the box at 1.173v at 4.4 turbo. I have took a screenshot but the post is being moderated.

As it is out the box as you say, then there is something wrong with the interfacing between your h100i, and your cpu.

Do you have the stock intel cooler to place on cpu to test?

Have you cleaned off and replaced the thermal paste between each time you un/re-seat the cooler and cpu?

As asked before, if you replace the thermal paste, what are you using? how old is said thermal paste?

If you not replacing the thermal paste, then there is an issue to start with that can cause the abnormal temps

1. 4.4 Turbo
2. 1.173
3. Default Settings no changes
4. These temps are when running handbrake and OCCT stress tester gives 5oC higher
5. No
6. Just CPU

Yes i have the stock intel cooler to use and test with. The thermal pasts are new and i have used mx4, as5 and now coollaboratory liquid pro and all make no difference.

It will run at those sorts of temps while you stressing the cpu, video editing / rendering and occt stress the CPU to the point it will start crying. The temps maybe a little high, but they are what is expected from what it is doing.

kl, but the temps seem to be very high for just out of the box and no room for overcocking it past boost.

When you run the machine normally eg games etc, it wont reach those temps, as the stress testing is pushing the cpu beyond anything that you would normally achieve unless you are transcoding videos, using extra large files in photoshop and applying some serious effects to the large image files, also 3d modelling / rendering etc, but a normal home user wont push the machine as hard as any of these things do, because when playing games etc, most the load for graphics etc gets offloaded onto the GPU (graphics card(s))

As said, yes they are a little high, but you need to give the thermal paste time to settle, also how did you apply it? pea sized blob and squeeze with cooler, or pea sized blob and spread it thinly as possible over the metal lid of CPU?

It might just be that you lucked out on the silicon lottery with the cpu, which wouldn't help with the temps etc.

I am just grabbing a file off my server, will then run it through handbrake and report my temps I achieve from it in CPUID HWMonitor, as I have the same mobo, cpu and cooler (H100i) so can get good comparison on it then for you as I know mine is running as sweet as it can without issues. (I am running it at the 4.4 turbo values so it same as you then)

Yeh thnx for helping man really appriciate it would like to know ur temps on handbrake can't wait. Its just a pea sized blob and a squeeze with the cooler. I have two 4790k's and they both do the same thing so i guess i just got crappy ones. My luck is always bad anyways any device i get is usually faulty at first lol. My 780Ti was faulty my capture cards were faulty and so on so :-(.

I spread it as thinly as possible and try for even thickness all over, I used MX-2 on mine I running now, so MX-4 should give slightly better performance.

So best advice is to spread it and hope that lowers the temps to normal, at moment handbrake is running converting to a blueray profile, its got about 10 mins left to run, but at moment temps are mid 70's

There's really no need to spread the thermal compound. Just put a rice grain sized drop on the CPU and let the cooler do the rest.

Temps went to mid to high 70's, am now running RealBench v2.2 stress test then will edit this post and upload grabs of HWMonitor from each of the 2 thing. I set realbench stress test to 15 mins and to use 8GB memory in case you wanted to run and compare also.

I am aware of this, I prefer to spread it myself, always have done and always had good temps as a result, which why I still do it that way.

Here are the results from the 2 different tests, as you can see in second one which I used realbench stress test, the cpu hit 84°c on 2 of the cores during that test.

Hope this helps, and you get it sorted, let us know how you get on with different heat sink if you swap over, and also try the spreading method of applying the thermal paste, (MX-4 preferably).

Yeh i got similar results but 86oC with real bench and 83-84oC with Handbrake. I might just delid the thing next week sometimes and come back and post to see the differences if its alot.

Fair enough
