    i7 6850k Temps High After H110i Pump Failure / Rampage V Edition 10 Board

    So, I was running an Intel i7 6850k OC'd to 4.3ghz / 1.35v on a ASUS Rampage V Edition 10 and a Corsair H110i for about 3 years with no issues, idle temps around 25-28c, full load under OCCT around 79c after 4 hours. Anyway, the other night the pump on my H110i failed, causing my system to perform a thermal shutdown when the CPU overheated. I replaced the H110i with a H115i, and since replacing it my idle and load temps are much higher than before...

    When I installed the new Corsair H115i, I went into BIOS on my first boot and reset BIOS to stock settings, no OC or anything. Temps were pretty normal on the first boot, around 32c idle, a little higher than the H110i, but I figured it was just cause it had just been installed. Anyway, rather than running any stress tests at that time, I went ahead and restarted, enabled my XMP profile, a modest OC to 4.0ghz. I manually set VCORE to 1.22, and then set all other voltages to stock manually, I don't leave any of my voltages on auto. Upon booting into windows my idle temps were now over 50c, and they have been since then. I've tried reseating the pump head. I've reapplied TIM a few times and can confirm a thin even spread, there is no contact issue. I've gone back to stock clocks. I'm not sure what else I can do to fix this at this point. Running a stress test in OCCT produces a 90c+ temp in less than 3 minutes. Pump speed is set to max, 2080 RPM, fans are running at 1100RPM on the radiator. Liquid temp gradually increases over time under load from 24.5c to about 31-32c, so there is heat transfer happening. Temps are relatively safe when gaming, editing and rendering video, etc... they sit at about 60-63c. CPU Package temp is always a bit higher than Core temps. When idling there is about a 20c difference, my cores idle between 26c-33c, while my Package temp never drops below 50c.

    What I am wondering is what could be causing the heat increase? I would assume this newer model h115i would produce better results than the h110i I had on before, but surely that isn't the case. Also the fact that I used to be able to run OCCT for 4 hours with a higher VCORE and never hit 80c, but now I hit over 90c within 3 minutes, is pretty alarming. Sure I can perform daily tasks and game, but I won't be happy until I can figure out what the issue here is... was something damaged because of the thermal shutdown? I have been told more than likely not the case by a few people on reddit/other forums, as that is the point of the TjMAX. Someone suggested that the contact between my IHS and CPU could be poor because of the overheating, but I highly doubt it. The i7 6850k was one of the last Intel CPUs to be soldered, so delidding is pointless, I also don't understand why I'd have to do it, as nothing has changed but the AIO, which I can confirm is working. No sign of blockage or bubbles, no leaks, etc. Is it possible the motherboard or CPU was damaged or is degrading and causing these heating issue? I built the system in Jan 2017, so it's only 3 years old. I have a 1600w EVGA PSU, I have also tested with a 1200w and that didn't change anything, so I know it isnt the PSU.

    Has anyone had similar issues with 68XX processor or my motherboard? I received a lot of support on the Corsair forums, but we couldn't come up with an answer. We just came to the conclusion that since the CPU is operating at a reasonable temp when performing my regular work/gaming that I should be happy. Hard for me to be happy with it though as there is obviously something going on. A helpful user suggested I try some other forums, so I figured I'd post here as well as the Intel official forums, I am going to hit the ASUS forums, I have a post on the ROG forum about this, and I am going to look for some more Intel/68XX specific forums.

    Any help is greatly appreciated. I've included some images for you guys to check out.

    Hi,
    Just sounds like a bad contact thing
    Repaste see if it helps.
    Make sure nothing is stopping the cpu block from touching the cpu.

    I am actually about to try rotating the waterblock... it was suggested on another forum. I am going to reapply TIM when doing so, I will probably do a manual thin spread, as I have gotten the best results with that. It doesn't appear that there is anything in the way of the block, it is firmly secured, by looking at the TIM it seems as if it is sitting flush, I have confirmed I am using the right standoff screws as well as the correct thumb screws, initially I didnt replace those and just used the ones that were on the board already with the H110i, but replacing them with the ones that came with the H115i produced no results. Also, just a note since it was brought up several other times in other forums, there is no backplate because I have an LGA2011, so a backplate isn't necessary.

    Thanks for your response, I will update after I play around with the block.

    Hi,
    Yeah rotating depending on where the hoses are located might help
    Most do it because if the hoses come out the side on the block them get too close to ram.
    If the hoses come out the face of the block usually won't help.

    Welp, I feel like a dummy... I could of swore I swapped the standoff screws when I installed the new pump, but apparently I didn't. After replacing them I an hitting a max temp of 51c after 3 hours in OCCT. Thanks for the help everyone.
