    So.. i discovered that my CPU fan is not moving.. and i think its for months already...
    i never discovered it before since my temperatures have been fine all the time..
    So im wondering.. is the hardware broken?....or something has to be changed in settings?

    (when played highly requirement games.. my GPU temp went quite high but CPU didnt raise that much.. but now that i discovered this i am avoiding playing games that would put alot stress on my pc.. since CPU fan not working is worrying)

    So question is.
    1. I need change some settings?
    2. If not.. and its broken.. should i bring my pc to specialist?

    what speed does the bios list for it

    are fans controlled by a setting in the bios

    check it is plugged in securely

    Well speed was ofcourse 0RPM
    And i checked bios settings.. and didnt see anything that would keep CPU fan off.
    Also tugged a bit wires in my pc.. and everything seemed to be connected properly..

    Kinda weird though.. fan could move freely.. even before i cleaned the dust.. so its kinda wonder why its not working.

    At least tempereture is still at normal. So i can browser and do low stress things.. without any risk of overheating.

    You're incredible lucky that it hasn't overheated. What are the highest temp it hits.

    Does the fan ever come on? Such as when you first press the power button? You can try plugging the fan into the fan header located directly below the CPU and see if it spins up on it. The 4 pin fan connector will work on the 3 pin fan connector as well just with PWM fan control, just line up the notches correctly.

    highest it goes so far is 47. That when im youtubing mostly in 720p. And doing weak stuff

    UPDATE: Checked pin thingy.. my CPU pin didnt have anything similar nearby.. and my CPU fan wont even move an inch. (it wont even react the moment i start pc)

    Get a new fan! It sounds as though that one is faulty

    Is this for the MSI motherboard in your specs or another computer? If another computer please list the full and complete specs of the system in question.

    cant edit my post some reason so sadly will have doublepost.

    Anyways. I found sysfan.. and its really inconvenient to reach..i mean i would have take whole CPU off to actually plug wire into sysfan.. and on top of that sysfan was already plugged in with another wire.. so cant really test without taking whole pc apart.. so im guessing best solution would be to bring my pc to specialists. Have guarantee active anyways..

    UPDATE: can play some games where CPU goes up to 70.. but the moment stress is taken off CPU temp goes back to normal.. so its still wonder that cpu temperature is stabile and not heating.. but yeah shall send it to repairs.

    You need to get it fixed.

    Most likely the fan has failed, with the second possibility being the fan header on the motherboard being faulty.

    Can the other fan that's plugged in the SYSFAN header reach the CPU header? If so plug it in there and see if that fan still works on the CPU header. That'll give you the same diagnostic result; if the fan works on the CPU header then it's the CPU fan thats faulty. If the fan no longer works on the CPU header than it's the CPU fan header thats faulty.

    Also, you should note that when the CPU hits its max temp, around 72/73 for yours I believe, it will start to throttle the speed to try to stop the overheating as excess heat will shorten or damage the processor. You should also note that the temp sensors on motherboards can be off or are not accurate so the CPU temp may be quite a bit higher. I'm surprised your temps are as low as they are, that's nearly unheard of without a working fan.

    My CPU max temp is 99. But pc will shut off for safety at 97. From what i know this cpu can go up to 80 in peace.

    ..but yeah.. in gaming highest point it goes is 65 or so..

    BUt i shall it send to repairs to fix the problem.

    Are you sure you are talking about the CPU fan and not a case fan? Or a chipset fan?

    The figures you mention don't make sense - a CPU without a fan running would be throttling the cpu speed and temps would be sky high.

    what cpu is it the only ones that max out that high i have seen are laptop cpu's

    generally they are around 65c mark max and start throttling back in the late 50's c
