    6700k High Stock Temps

    My specs are as follows:

    Maximus 8 Hero (Non Alpha)
    i7 6700k @ stock
    Radeon R9 295X2
    16 GB 2400 MHZ Corsair Dominator Platinum DDR4
    Seasonic 850w Focus + Gold PSU
    Corsair H80i V2

    Temps are very high for medium gaming, I am afraid to see what they would do in something like Prime95.

    Here's an HWINFO64 screenshot...



    As you can see by the max temps I am getting ~85C at stock. No overclock of any kind.

    I have tried putting LLC to 5, I have set vcore manually to 1.28. I have reseated the cooler and reapplied thermal paste (Noctua NH-1)

    Got any ideas?

    Max Vcore is 1.296ish, according to HWINFO, I manually set it to 1.28 in the BIOS.

    BIOS is also up to date.

    My case is a Cooler Master Cosmos II with at least 14 fans total, with the CPU rad venting out of the top and the GPU rad out of the back. I might try swapping them...

    Most of the fans are high performance Yate Loons/Scythe Slipstreams...

    Room temperature is 70-75F.

    I personally never like that many fans in a case because it's difficult to determine where that air is actually going, and how much of it is trapped and recycled inside that case.

    Try setting the Vcore to 1.15v - 1.20v.

    Alright now under the same conditions max temps go to 70-75c, still kind of high for a good liquid cooler with a thick rad like the h80i v2.

    I set VCore to 1.175 and now it maxes according to HWINFO at 1.184. Humm... Might move rads around...

    That's looking better !

    When you installed the H80i did you use the pre-applied thermal compound on the waterblock or did you use your own? If you used your own did you remove the pre-applied thermal compound ? Also make sure the waterblock is making good contact with the cpu, not super tight just snug. Make sure the pump is running at 100% too.

    I'd remove the stock thermal compound and use Thermal Grizzly Kryonaut, this should help lower temps a little more.

    I would check the mounting and thermal paste.

    Even when mine is hitting 1.4V under load it doesn't go higher as about 80°C on Prime!
    Gaming is 60° max when the Water got warm. (And thats all on very low Fanspeeds).
    But i use a custom loop with 280mm Radiator (thin one)

    Oh, i forgot. Mine is delidded and the Factory paste is exchanged. Might also be a factor.

    Swapping rads around will not fix your problem. Something must be wrong there. Either the cooler/paste is not on properly or the water pump is not working. Or maybe the cooler has air bubbles inside? Although you should be able to hear a bubbly noise from the water pump if that was the case. Silly question, but did you connect the pump to a voltage source?

    My 6700k barely reaches 60C under 100% load with a H110i rad. Temps usually settle around mid to high 50s under full load. CPU is running at 4.6GHz, LLC-6 with Cache at 4.5GHz and 3466MHz on mem. Voltage shown in HWINFO is 1.249v. I can't remember the exact setting I have in the BIOS but it's around 1.235v.

    My 6700K under load was 55C-60C with a Lucifer V2 air cooler. Based on your temps it seems your cooler might be the issue, here. As pointed out above it would be a good idea to reapply thermal paste (don't cheap out, get a good one) and re-seat your cooler.

    Couple of other things, though. What are your ambient temps? And are your CPU temperatures constant? I noticed that my 6700K had severe voltage and temperature spikes that would reach 75C-80C before I changed some BIOS settings.

    Just to clear up one last thing, you mention the H80i as your cooler, but you swapped that for a Noctua NH-1 to check? Is that correct?
