    Hey guys.. The story is quite long but I'll try to explain as simple as possible :

    Oops, forgot the specs :

    CPU - i7 4770K
    GPU - GTX 780 WINDFORCE OC
    RAM - 16 GB Corsair Vengance Pro Series
    SSD - 128 GB Corsair Neutron
    PSU - Corsair RM750
    Cooling - Corsair H110

    Heat readings #1 (win) : http://www.youtube.com/watch?v=13F30feBWhI
    Heat readings #2 (bios) : http://www.youtube.com/watch?v=moDGnaabQLc

    • I was lucky to win a PC and it came already built.
    • At the first windows boot, everything was ok for the first 10 minutes then my Nvidia Kernel Driver started to crash every 1-2 minutes (exactly when the cpu temp reached 100 degrees celsius).
    • After I tried 10-12 drivers, fresh OS etc, I conceded that the GPU hardware was faulty (false).
    • I went into BIOS to check for factory OCs but everything was on minimal/default.
    • I realized in BIOS that my CPU temp was 91 degrees celsius (first morning boot). I immediately closed the PC and let it chill for 30 minutes. Then I started it again, and went directly into BIOS. The temp went from 72 degrees celsius to a stable 91 degrees celsius in 5-6 seconds.
    • At this point I was quite angry and I realized that I used the CPU at that temp for more than 12 hours. From my pov a CPU would fry at that temp in less than 10 minutes, so I kept the PC running with that temp.
    • I checked the thermal paste. Photos : http://imgur.com/a/3gmPz .
    • I checked if the heatsink actually stays on the CPU without any space between.

    Also I recorded my readings in HWMonitor/Speedfan/RealTemp/BIOS. I apologize for the foreign accent and bad english. This is my first actual gaming rig and I'm quite the beginner when it comes to building the actual rig.

    About the thermal paste, I already ordered Arctic Silver 5 kit (remover/purifier/paste) just in case I'll need it if you guys say that the paste that's already applied is faulty and needs changed.

    My beginner opinion is that it's a faulty heat sensor on the motherboard. The CPU can't be actually at 91 degrees celsius. It would burn to a crisp, and I already used the PC for 12+ hours.

    What kind of cooling do you have on you CPU? As of the pic, i'm guessing a closed loop watercooling kit?

    If so.. how is the power for the pump connected? To a fan header on the motherboard? Or to a molex connecton from the powersupply?

    Had the same issues with my old i7 920 platform.. connected the pump to the motherboard fan connection and did not get enough juice to the pump.

    Yeah, sorry forgot to mention the specs silly me. It's Corsair H110. But you lost me on the power source for the pump. Took 2 more pics with bad light and found one better pichttp://imgur.com/a/OG78N

    Well i had a CoolIT ECO 240 system.. when i connected the power for the pump to a fan header on the motherboard as instructet in the manual, the pump did not get enough juice to get proper waterflow even if monitor software told me that pump was running at 4400RPM. Had to connect it to a molex with a 3pin fan header to molex adapter.. worked perfectly then.

    Find you wich fan header your pump is connected to and check the bios settings for said fan header. Maybe try to connect it to the CPU fan connection and turn of any "Silent" fan settings for CPU.

    I LOVE YOU! The guys from Nvidia who built the rig didn't plug the pump at all.. Cool cool..

    i get this with my Corsair H90 p/p fans ~ 1200rpm @ 4.6Ghz (1.227v adpative), using Noctua NT-H1 paste

    Sensor test

    Idk that looks like a H110 pump issue or poor thermal paste choice..



    EDIT: ah so it was the pump, lol noobs xD


    what temps do you get now in uefi, etc?
