Bad 4790K?

[CalebTheEternal]

So I just picked up a 4790K and I think my temps might be to high... I was using an H100i Liquid cooling loop and on minecraft I was getting around 80-90 C and so I went back to the stock cooler. Now on minecraft I'm still geting 70 C Is this to high? Do I have a bad CPU?

did you try remounting the cooler and re applying thermal paste?

[Atmos]

I don't think so. Make sure the coolers are properly latching to the cpu socket, and make sure that you swap the stock thermal paste out for something better.

 

A couple things can cause issues like this, you first need to check some stuff before jumping to conclusions.

Only about 100 times.....

I've re mounted multiple times, used 3 different thermal pastes and used different fans on the H100i, I even tried the O ring trick...

[cesrai]

You sure the H100i is functioning probably ?? 

[Battleship Yellow]

is your h100i circulating properly are you making sure to get a good seal between the water block and the CPU

[Chronos5618]

Sounds like a bad mount to me. Try removing it and starting from scratch. Should not be that high.

Well I'm not sure... On my old CPU (3770K) with a 4.2GHz overclock I would get to 90-100 with ease. But are these temps to high for the stock cooler too? I tried re mounting it multiple times..

Those temps on a stock cooler OCed I wouldn't be surprised. 

 

I know this may sound stupid but did you use alcohol to clean the thermal paste ??

It's not overclocked. This is on stock voltage and everything. The overclock I was talking about was for my old CPU. This one has NO OVERCLOCK.

 

Yes I did clean it with alcohol. Scrubbed it for a LONG time.

Those chips shouldn't be anywhere close to 90-100 with a h100i, my h110 had a 3570k (4.2) around 45-55 in games, 65-70 stress and has my 4790k @ 4.7 around the same temps with ic diamond 7 paste

 

It sounds like ether the h100 block isn't mounted correctly or plugged in, if it is mounted correctly / plugged in it probably faulty.

That's what I thought. Stock cooler temps fine or are they high?

I meant the 3770K temps with the stock cooler.

 

I bet the problem is related to the H100i, maybe the fan speed - but this is a really really long shot - ? or the pump isn't working probably.

RMA the H100i? Corsair has been known for bad pumps on their AIOs.

My Xeon E3-1230 v3 hit 86-90C on the stock cooler with NT-H1... Many other people with my Xeon have it get that hot on the stock cooler, and Ivy had shitty IHS so it doesn't surprise me one bit. @Gofspar would get his 3770k pretty hot before the delid overclocked on his X61...

[Un4tural]

why nobody suggest it yet? just touch it with hand, the heatsink, see if it gets really hot, which is unlikely,. for the stock if mount is bad.

 

i've heard h100's had bad plates, some of them, so that might be the issue?

 

70 on stress test sounds high but not too high i wouldn't think.

OK I will defiantly RMA it then. I also have a Hyper T4  cooler but that thing is a pain in the ass to get on so I'm not going to test that... I spent 30 minutes trying to get that damn thing on.... Idle temps are now around 35-40 on stock cooler.

I've heard T4s are a pain to get on, hopefully your next unit actually works correctly.

70 for the stock cooler with no oc sounds about right, that is really close to what my friend gets with his, I get about 65-70 at 1.3 volts at 4.7 with my 4790k with the intel stress tester

Check voltages, eventhough they're stock. What actual voltages is the board using, because it could very well be too high with an ROG board from ASUS.

1.3-1.4 V too high it seems.

[Majestic]

1.3-1.4 V too high it seems.

 

Can you post a screenshot in that topic? That's number 5 I believe.

 

Try updating your BIOS, in some cases that fixes it. Otherwise you have to use an offset voltage of -100/-200. Whatever your processor allows.

So I just picked up a 4790K and I think my temps might be to high... I was using an H100i Liquid cooling loop and on minecraft I was getting around 80-90 C and so I went back to the stock cooler. Now on minecraft I'm still geting 70 C Is this to high? Do I have a bad CPU?

so im going to let u in on a secret that corsair didnt fix yet u need to go get 4 plastic washers and putt them on the back where the back bracket is for some reason the newer mother boards arnt as thick had to do this on alot of z97 boards

i7 4790ks do have a tendency to run toasty.  I've actually been through two of them.  The first one, I returned because it was hitting the thermal limit and shutting down to prevent damage.  This was with a stock voltage of 1.21v and the stock cooler.  With a Cooler Master N520, it was hitting 95 with stock settings.

 

The second one wasn't doing much better but at least its staying below 100 with the stock cooler.  the CM N520 was doing about 90.  I also got a Corsair H80i and that took the temps down to 85.  I eventually caved in and built a custom loop to keep the temepratures somewhat comfortable in the 70s with a 4.7ghz overclock and 1.27v. 

 

The whole point of the 'Devil's Canyon' CPUs were to fix the Thermal Interface Material problems the original Haswell CPUs were having but in actuality, it's still a mixed bag.  There are some telltale signs of a bad TIM such as idle temps that are uniform but under load, one core would be drastically different from the other three.  If you've checked and double-checked that you applied the thermal paste and set the your cooler properly and if you've also checked that your MoBo is using up to date bios and there are no gremlins there, I'd honestly bet your problem is the TIM and unless your temps are causing BSoDs under the stock settings, there's really not much you can do since the product is technically operating within Intel specs.

Wow ok.... Well I just tried playing Battlefield Hardline on max settings and I hit the TJ max after about 45 minutes.
