4790k heat problems

[mao91]

Alright, so the editing guy at the media company I work for is having issues where his 4790k can't keep up with playing back color-corrected 4k footage in Premiere even at half-res. If he tries to go into multi-cam, it won't even play back at 4k for more than a few seconds before it starts getting choppy. CPU is maxing out at 100% utilization & 4.32GHz, peaking around 83 C. 

CURRENT HARDWARE CONFIG:

CPU: Intel Core i7-4790K
CPU Cooler: Stock
Motherboard: Asus z97-PRO
RAM: 32GB DDR3
Graphics cards: EVGA GeForce GTX970 & PNY NVidia Quadro K2200
Drives: 2TB 7200RPM, 4TB 7200RPM, 500GB 7200RPM, Crucial 500GB SSD
Case: Fractal Design Define R4
Fan layout: 2x 140mm front intake, 1x 140mm rear exhaust
PSU: Corsair HX850

 

We have a Noctua NH-D15 coming tomorrow to help deal with the CPU temps issue, and to hopefully give us a little headroom for overclocking, and another 120mm fan for bottom intake in the case to address ambient temps around and between the graphics cards. Still, I'm curious if there's something more I should look into. Is it possible that the 4790k just can't handle that heavy of a workload? We're trying to keep our costs down as much as possible, so if there's anything I can do that doesn't involve "just buy a Titan X or Quadro K6000" or something like that, I'm all ears.

Well the i7 4790k is a hot cpu, switch out the cpu cooler, its not sufficient.

The new Noctua D15 cooler will definitely help.

Go with a Cooler Master Hyper 212 evo or something.

 

As stated, we have a NH-D15 coming tomorrow for that. The primary issue here isn't the heat, but the fact that the video playback is choppy, and that it's not rendering like it should, and that it's causing the CPU to max out.

I would say seeing what this computer is being used for just install the new cooler and keep the CPU at stock settings, reliability should come first.

It's normal, you shouldn't be overclocking with a stock cooler anyways and I'm guessing the voltage is on auto isn't it.

Alright.

I did an auto-overclock tuned to keep the CPU under 83 C, yes.

To get a more powerful cpu you will have to go over to X99 which is expensive.

 

Maybe something like this would be in your interest:

Yeah auto overclocking is kind of bad you should manual overclocking as most auto overclocks put more voltage on the CPU than it actually needed meaning lower overclock and higher temps

That's what I figured in regard to the CPU. Thanks for the video about that gfx card, something to think about for sure. Would more VRAM help this issue, or is it kind of a "meh" point?

Luckily the editing guy has the day off tomorrow, so I should have a little time to actually tinker around with that... as long as nothing else comes up.

Okay, the D-15 looks a LOT smaller on youtube... Holy crap this thing is practically the size of my face...

 

 

... but I took pictures and made a video!
