Another temp topic

[App4that]

Sorry for another temp topic but this is strange and I can't seem to find another case like it.

 

Just picked up a 4790k and I'm finding it to run hot. I have it at 4.6GHz on the core and 4.7GHz on the north bridge. Vcore voltage is 1.21v. It has been stable but I hit temperatures as high as 85c in AIDA64, in Cinebench I stay under 72c. The temperatures drop immediately after the load is removed. The temperatures of the CPU change with ambient temperature. I have a 8 degree temperature difference between the cores, 3 stay very close to each other with core 4 staying much cooler than the others. I have a Corsair H105 cooler with 2 stock Corsair case fans and 2 SP Corsair case fans in a push/pull arrangement. The radiator gets hot and the pump is spinning at 1800rpm.  The push stock case fans are powered by the motherboard and are at a constant 1200rpm while the pull SPs are powered by the fan controller and fluctuate between 900-1200rpm depending on case temps. 

 

A lot of the resources I've found say to keep the 4790k below 72c, so that's the goal. And for the most part I have reached that but I do see spikes into the high 70's during heavy gaming. I used Arctic Silver for the thermal paste. So not sure if I have an issue with the seat of the cooler, or if this is just how this particular CPU behaves.

That's fine. AS5 has a cure time according to most sources.

 

85c is fine under stress, up to 90 is acceptable.

Seems hot to me. I also have the 4790K and H105. I have it at 4.5GHz with 1.13v and temps never hit 60c. Try cutting back on the volts, redoing the thermal paste.....

What's odd is I've seen people using over 1.3v at the same clock speed with lower temps though. So ether my cooler sucks or my CPU runs hotter than usual.

I get similar temps at that voltage. Once I cross 1.2v the temps spike but I need 1.2v for stability on the Overclock.

You could lower the VCCIN, I think it is set to 1.8 by default (which is higher than needed, mine was, though my board will only lower it to 1.68 at lowest) lowering it could lower temps, or give you a blue screen like with any tweaking.

Some corsair coolers have mounting issues. Have you tried the washer method? It seems like that may be your problem since you've got one cool core and 3 hot ones.

There was a noticeable difference in how the screws tightened. I assume you put the washers on the mount behind the MOBO (between the backing plate and motherboard I should say)?

I misread the cooler for a lower end unit (H55 somehow) so that is a bit higher than you'd expect. has it only been recently mounted?

 

The washer suggestion is good, I had to do that for my H80i on LGA1155 and saw a 13c drop on the hottest core.

I don't know, as I've never had to fix this problem. Google H100i washer method and you should find what you're looking for pretty easily.

Going to try and remount the cooler, and see if I can find washers. Hopefully that works as this CPU is good for 4.7 easy if I can keep it cool.

I would say something is wrong with the cooler of yours. I have a 4790k 1.25Vcore and a Hyper 212 Evo and I get similar temps to you. It's a nice overclock you've got though, but I have to think that something is wrong with your cooling. 85C is fine for the CPU to run as a peak temperature, but the H105 should be performing better

Thermal paste was off, it was only on one side of the CPU. Running AIDA64 again and highest peak temp was 80c on one core, average in the low 70s. Also put washers on te back plate of the cooler.

Hehe. You really gotta apply that shit well.

 Yes, this is not how you apply it. :lol:

 

 

 

 

Temps are more stable, haven't crossed past 80c even in Aida and the average temps are way down. Hopefully I fixed it. Thanks all!

No problem bud! Have fun benching that beast! I get 4.7@1.25Vcore in my minimal testing I've done. What about you?

I've got my 4.6GHz overclock steady at 1.21v, calling that my daily driver OC. Going to bask in the glow that is a i7 for a bit then see what she'll do.

Ive done this so far.....very rough OC

You my friend are a brave one, I wouldn't be brave enough for voltage that high. I'm still trying to work up the nerve to go past 1.25 so I can run 4.7GHz LOL

[Wingfan]

lol only ran it for 6 min's one time. I still havent really tweaked it yet, but dont really need to push for that high GHz when 4.5 is good enough. But only 83c with that much voltage seems pretty good to me for temps

That's really good. And my in game temps have plummeted with the reseat of the cooler. Yesterday I hit 79c as a high playing Fallout 4, today my peak temp was 66c. And most of the time I was i the 50's. WAY better.
