After searching Google for hours I haven't been able to find a solution since recently my cpu liquid cooler is no longer detected in bios theres some lighting on the front as well as a button to change speeds and they are on I've checked the cable connected to my motherboards cpu fan port and it appears to be fine how ever the temperature still rises quickly

The cooler is a corsair H100 and my motherboard is a Asus z97-k

Update: It's randomly came back but for some reason the rpm will not go over 500 and yelling at it hasn't increased the rpm
 


Ya I thought that to but this morning I booted it up and it's perfectly fine again running at 2000 Rpm like nothing happened
