Windows 10: CPU fan issues

    CPU fan issues


    Hey everyone,

    Been digging around for a few days and haven't been able to find an answer myself so I figured I try here.

    My CPU (i7-6700k) has been running hot (90'C+). The other day I noticed the fan wasn't even spinning while that hot and even when hitting 100'C. Also noticed my CPU cooler was making weird sounds, so I went ahead and order a replacement (Corsair Hydro Series H60). Got it today and after finally getting that thing figured out and installed...no change. I made sure everything was connected properly, went to corsairs website to make sure no downloads were required, went into bios and messed with the CPU fan, updated the BIOs and even downloaded an App that could mess with the CPU fan (speedfan) and still cant get the fan to move. Im sitting above 70' almost immediately and around 90'c most of the time. Would really love any ideas, I'm really close to handing this off to some more computer savvy types and letting them have at it.

    Thanks

    Do you have the fan plugged into the CPU Fan header? Is the CPU Block making good contact with the CPU, did you clean off the old thermal paste before installing the new CPU, which already has (should have) thermal paste applied.? Are you sure you have it installed properly and the CPU Block screwed down pretty snug?

    I would get the fan running right before running the computer. Your temps are getting critical.

    Since you said it is a 6700k, did you overclocked it in anyways? If you have, I would reset it via 'clear cmos' to get it back to default. If it is overheating still, then CPU and the coldplate of the cooler isn't making good enough contact. Which would follow on Essenbe's post.

    Can you explain just how did you connect radiator fans and pump ? For now, it looks more like electrical, connection or BIOS problem and no OS or programs can fix that.

    Thanks for the response. All the connectors are where they need to be and have been double/triple checked. I used the thermal paste that came with/on the corsair...im looking into other paste atm, might give that another try.

    Never overclocked, never needed too. Looking into a better thermal paste than what was already on the cooler when it arrived

    Better thermal paste is not a solution. At best, a better thermal paste may help 2-3. That's not significant with 100 temps. The biggest issue right now is why is the fan not turning. Get it running right and I think you will see a big difference. It should be connected to the CPU fan header or another fan header on the motherboard. Failing that there is a fan adapter that connects the fan to a molex connection straight from the PSU. That will cause the fan to run at 100%.

    Solution 1:
    Put a 3 pin cpu fan in the motherboard.

    Solution 2 :
    Put a chassis fan in the cpu fan header.
    And the cpu fan in the chassis header.

    There exist also a bug in as-rock motherboards : When u have cms (compatibility mode) enabled the fan don't speed up with temperature change.

    Have you tried installing and using SpeedFan? It's a well-known and generally reliable (free) fan speed management tool. This will at least show you if you CAN control and manage fan speeds, even if you decide not to use it permanently.
