What I've tried:
reapplied thermal paste
reseated cooler
cooler (h110i gtx) was taken from a different x99 build where it worked perfectly

this is a new system that was put together 2 days ago. (5820k, asus x99 deluxe ii)

ambient: 20c
case: fractal r5
air flow is corsair h110i gtx intake to cpu (push/pull with stock fractal fans/stock h110i gtx fans), 1 rear exhaust (980 ti hybrid, rad + fan), I have the rear top modu vent open to allow heat to rise out.

I did no OC the first day, optimized "auto" settings had me at 3.6 ghz @ 1.059v / EIST on / C-states on
idle: low 30's, aida 64 100% load: high 50's low 60's

Today I went for OC, went to 4.0 @ 1.1v / EIST off / C-states off
idle: low 40's, aida 64 100% load: mid 80's (hit 89c on 1 core then I stopped test)

I now sit at 3.6 ghz @ 1.0v / EIST on / C-states on, until I can figure out the temperature issue.
idle: high 30's, aida 64 100% load: high 60's, touches 70-71

Not sure why my temps are higher now than day 1, since my core voltage is lower now. ambient remained the same.

The only thing I can think of is that heat is getting stuck inside the case and I should add a top rear exhaust (when I put my hand up to the back of the case where the 980 ti hybrid exhaust is, I do not feel a lot of air coming through) I would greatly appreciate any help / advice.

thank you for your time.

Having lower temps with the case cover on is a sign that you're doing things right. I would keep the current...

Case airflow does more than most people think (I think). I have the same cooler as you, and I added 2 additional intake and exhaust's to my case, for a total of 4 intake and 4 exhaust in a Corsair Obsidian 750D, and instantly dropped ambient by around 5-7 degrees, and load 10-15 degrees. Try a better thermal paste perhaps, for example I'm having extraordinary results with Coolaboraty Liquid pro metal paste. Also make sure your the speed of your pump is maxed out to 3000 rpm. Default is around 2k i think. Idle temp's on a 6800k 4.4 Ghz @ 1.35 volts with power saving stuff disabled and OC'd cache sitting around 30 degrees, with load temps nearing 65-70 degrees, for reference.

You shouldn't run the AIDA64 FPU-only test when overclocking Haswell-E. It causes spikes in current draw that can fry your chip. It's not uncommon for an overclocked Haswell-E to hit 90 degrees in that test, even with good cooling. What are your temps under more realistic load situations? Cinebench, Real Bench?

@bottlegamer

ok i will try that.



rendering with sony vegas gives me 97-99% load, seeing temps averaging around 75c, not past 80. this is at 1.01v (got stuck on splash screen this morning with 3.6 ghz @ 1.0v)

You must have some case air flow issues. My temps are more than 10C lower than yours rendering in Blender (using CPU only) and I have an air cooler and a much higher overclock. You should be below 60C at 3.6GHz/1.0V. Do you have any pictures of your setup? Don't misunderstand, your temps are not dangerously high by any stretch, but they could be much better, especially if you plan to OC higher.

I removed the side of the case, temps remain the same. I will take some pictures and upload tonight, late for work at the moment.

I know the pictures aren't the best, but hopefully it gives an idea without me having to pull this 70lb brick out of the corner. Let me know if there is something in specific you'd like to see.

Here is a pic of Aida test I just did, I have had air conditioner on 17c for 6 hours while I was at work. Room is a freezer, still hit 85c in a few seconds. And this is with all voltages and cores set to "auto" with EIST ON.

edit: tried ASUS realbench, hit 83c

edit 2: i loaded optimized defaults from mobo, upon startup pc says invalid boot signature. i delete pk value, get into windows, idle @ 46-47c, aida: 82-85c

It looks like your fans are blowing cool air across the radiator and then into your case. This is filling your case with hot air and causing everything to run hot. I would try flipping the rad fans around, and convert all your others fans to intake.

83 is RealBench is crazy-high. You should literally be 25C cooler at your present OC.

I'm sorry if I am misunderstanding.

You want me to try the H110i GTX as exhaust on the top? and use the other fans as intake?

Yes. I actually thought your H110i was mounted to the front, not the top, but I still think you should try that.

Ok, I will see as to what effect it has. Although, I do have the side of the case open and I've stuck my hand inside and I don't really feel any heat building up inside the case.

To no avail, I am within 2-3c of old temperatures.

What I am having a hard time understanding is why I was under 60c full aida load on day 1?

Being that I am not very knowledgeable about CPU cooling, is it possible to "burn away" the thermal paste when I hit 89c? Then I went back to day 1 stock settings and all the sudden I'm at 80c full load. I just don't understand. This is so frustrating, I'd love to just pay someone and be done with it. 4.0 1.1v 30c idle 60c load, all I want. Is it too much to ask? Every post I read is someone at 4.5ghz 1.3v @ 30c / 70c. Either everyone is lying, they all live in freezers, or this is just a sick joke. The side of my case is off, my room is cold beyond comfort, nothing I do gets this PC below 45c.

Anyone around NJ/NY build custom loops? I'd be happy to pay anyone who could get me some ACCEPTABLE temperatures.

I live in NJ, and I get paid in 7-11 Coffee :)

But before you throw your PC in your trunk and drive here with it, let's rule out a few things :)

Do you have your pump running at full-speed? Have you tried to reseat the block yet? The thermal paste would not "burn away" but your waterblock could be seated unevenly.

Perhaps we could arrange something :lol: haha

Pump is at 2300 RPM, I believe that is full speed, I am only given one option in corsair link. Is there somewhere else I could adjust pump speed? When my friend was over earlier, we reseated block and did paste (pea size amount). I prefer not to do those things alone, too worried about damaging something. I am at 45c now while watching HBO GO, on demand video online. Also, I have a Seasonic 1000W Platinum PSU, just in case that is of any importance.

edit: Open Hardware Monitor shows pump at 2319 RPM

I'm at a loss, my friend. There must be something wrong with your cooler. I would tell you to check your fan speeds, but unless they were completely stopped, they wouldn't explain why you're running 25C warmer than you should be. I would max them at ~2200RPM anyway just to see. Even if you just had a big air cooler, you would be at 60 in Real Bench at 4.0/1.1.

I am trying to use speedfan to adjust my pump RPM as others said they have used 3000 RPM, but I am unable to adjust it. Perhaps I am not plugged into a CPU header with a PWM connector some video said? sigh.. wish I knew more about all this.

Here's a picture of speed fan, nothing is adjustable?

edit: looks like I am plugged in the CPU_FAN header on the mobo by a 3 pin connector. I tried adjusting the speed with speedfan, BIOS, and Corsair Link, all to no avail. Perhaps the pump is defective? Or am I unable to change the speed because I am not on 4 pin?
