I've actually posted about this before, but I don't think I've solved the problem.

My 4790K, with all settings (clock speed, voltages, etc.) completely stock in the BIOS, is running really, really hot seemingly regardless of cooling solution.

Here's a HWMonitor screenshot with the stock cooler: http://i.imgur.com/xxGC3pY.png
Taken while writing this post, no stress test/benchmarking or anything, I'm looking at around 60C idle, and 80-99C under load.

Ambient temp at the case's front intake is ~23-24C, 30C at the rear exhaust

I had similar results with a Corsair H100i AIO liquid cooler: http://i.imgur.com/LIzsJ9H.png
The cooler is currently shipped out to get RMA'd, but it seems it likely wasn't the issue considering the temps on the stock cooler are pretty discomforting too... That cooler was installed with Arctic Silver 5 (pea method) almost a year ago, and re-seated a couple times, so curing time/ bad installation is definitely not the issue.

If it helps, the CPU was purchased from Amazon in March of 2015, so it should still be covered by Intel's warranty, but I can't return it to Amazon.

How do I go about fixing the issue? Is it possible it's the motherboard and not the CPU?

That's what I'm worried about. How do I go about getting in contact with Intel? I've taken a look at the site but was unable to find any kind of warranty/RMA info.

I don't have the H100i atm (Shipped out for replacement like I mentioned in the OP), and I had been using Link while it was installed. Link reported the cooler's temp at 30C, but every other monitoring software (and the debug display on the mobo) was saying 50-60C idle.

Is there anything running in the background you are not aware of that is running? Perhaps something is putting a load on the cpu without your knowledge thus skewing your temps?

I have the same cpu with an h100 oc'd to 4.6ghz with turbo off and I'm idled at ambient temps.

Ok I'll check back when I get the replacement. My main issue is that I do a decent amount of video rendering work, so I'm actually hitting 80-90C quite often on stock. It's even hit 100C (per HWMonitor and the mobo's debug panel) with the H100i during a Prime 95 test, which is why I RMA'd it thinking it was 100% the issue, and why I want to get in touch with Intel if possible.

GPU and other components are sitting at expected temps, so I can't blame ambient, either.

In that case you can contact Intel support especially the none prime case.

Both HWMonitor and NZXT Cam are showing CPU load at around 14-16% (So yes, there's a bit of load, but nothing that should be causing those temps even on stock cooling), and a temp of 60C, And I haven't run anything else since I powered on tonight. The issue has been persistent for at least a few months now.

Just read your other post. Even with Handbrake I'm in the 75 to 79C range under full load. How were your fans setup on the water cooler? Mine are setup to pull air through the radiator which is what the manual said was optimal.

I'll assume you set it up the same way. The only thing I can think of is the mounting of the cooler and whether or not it could be loose, or just not tight enough to be seated properly.
Just looked at mine and the corsair has thumbscrews that screw into standoffs, cant really go wrong there. Since you don't have the water cooler you cant check the standoffs.

Did you remove the stock thermal pad/paste before using the Arctic Silver?

I'm trying to think of everything.

Originally had the fans pulling air through the rad and in from the top of the case, but I eventually turned them around to push through the rad and out the top, with no change in temps either way. Also, I do tend to keep the filters pretty clean by washing them out once a month or so, so there's not much dust build-up to speak of.

As I mentioned I blamed the cooler at first too, but I'm still getting terrible temps with stock as well, so it seems it may only be part of the problem if at all. Yes, the old paste was always removed with isopropyl alcohol prior to applying the AS5 on each install.

Funny thing, though, I don't know if the MSI Z97 Gaming 5 is a thin motherboard or something, but the backplate standoff was always just a tad loose even with all the screws fully tightened. Didn't budge at all once the cooler was installed, though, only without it. (Can't really explain that all too well without video, but without the cooler here I can't provide that just yet).
The stock cooler is on snugly with the regular ol' plastic push-pins...

When I installed the stock cooler after shipping the H100i I left the Intel-applied paste alone since I didn't want to be essentially wasting the AS5.

Thanks. I submitted a request there a couple days ago, but I have yet to receive a reply. I'll try the Live Chat option on Monday and see if that helps.

I assume you have double checked all the pins are inserted all the way on the stock cooler

What's your case airflow like how many fans?

Does it help if you leave the side panel off of your system


Also what is the make and model of your PSU?
As your 12v rail is very low and out of spec at 11.1v especially to say its not under high load

Yeah, I'm looking at HWMonitor, NZXT Cam, and the debug readout on the board itself.
They all do match as far as package temp, of course the individual cores differ slightly between each other.

Airflow if good, this is my second build in this particular case (CM Storm Trooper). 2 intake fans, 1 exhaust out the back, and when the H100i was installed, 2 blowing through the rad and out the top. That slot is empty atm while the H100i is out to Corsair (I'm using the stock cooler right now until I get that back).
Side panel doesn't make much of a difference.

I hadn't actually thought the PSU being an issue, tbh.
It's an EVGA Supernova 1000W supply, and it's the newest installed part of the system. Though the temps haven't changed since it was installed, they've been the same since I first built the rig back in March.
I do have the old 700W OCZ ModXTream-Pro, might actually try switching it in and checking again if you think that could be part of the issue.

I have a multimeter, so I'll look up how to check the voltage on the EVGA manually, too.

Everything is set to stock, but I can double-check and give you an actual number in a little bit once I'm finished with a bit of work.

In any case, should I be worried at all about the lower voltages it's giving? I.e should I contact EVGA about it at all or would it not be worth it to ship back?

Update for everyone helping me out here: Intel is replacing the CPU, in addition to Corsair replacing the H100i.

If both of these don't solve the issue, I'll try my other PSU, just in case it's a voltage issue as ccampy suggested. If THAT doesn't solve it, then it really only leaves the board, (possibly something up with the power delivery? I'm no expert, obviously xD ), so I'll get in contact with MSI about it.

Thanks a bunch!

The BIOS was updated via MSI's LiveUpdate utility a few days ago when the Intel rep mentioned it, no difference. As of 08-2015, the latest version is 1.C, (http://us.msi.com/product/motherboard/support/Z97-GAMING-5.html#down-bios) and that's what is on the board now.

I do in fact recall reading something about some kind of BIOS update being needed for some Intel chips, so that is a very good point. Looking at MSI's site, it may have just been 5th gen CPU's, though.

As it stands the CPU is getting replaced by Intel, and same with the cooler via Corsair. If I'm still having heat issues after both of those are replaced, I'll first switch out the PSU with my other 700W, just in case, and then get in contact with EVGA (if PSU issue) or MSI (if mobo issue).
