Hey LTT.
Short run up to my problem: Last night, no problem at all, this morning, no problem at all, but a few hours later when I got home from the gym my fans were running FULL speed and MSI command center was saying 99°C on my CPU temp measuerer so I semi-panic and check things out, joblist is showing my CPU to be running at less than 10% load.
I turned my system off and on again and it's still the same problem. I turn it off and take it for disasembly, cleaned the CPU, the cooler and added new thermal paste while resetting the BIOS. I also tried as best as possible to see if there was anything wrong with the liquid inside the cooler, but since I didn't want to void the warranty I did not open it up. I tried shaking as best as I could and it seemed like there was flow for the liquid, so no gunk stuck in the tubes.
Taking it back to my desk to test if that fixed it, I load it up. The motherboard doesn't give me a error code in the two digits, so I load up BIOS and look around and after a minute or so, the fans starts going crazy again and I look at the monitor page and this is what I see...
Now it says the CPU fan 2 isn't running, but I could visibly see that it was spinning at full speed, hear both of them and also feel the air.
Just for the sake of it, here are my system specs.
Cooler Master G750M, 750W PSU
Cooler Master Nepton 120XL CPU Cooler
HyperX Beast DDR3 2400MHz 16GB (Kit of 2)
MSI GeForce GTX 970 4GB OC
Corsair Obsidian 450D Midi Tower Black
Intel Core i7-4790K
My system is just about 1 year old and wasn't overclocked when this happend.
I suspect it may have something to do with the CPU coolers measurer, but to be honest I have no idea what it could be at this point.
I hope that any of you guys may be able to come to my rescue with this problem.
