Processor Fan header seems to be dead, change motherboard ?

[z3r0]

When I was working on my PC it suddenly turned off, I tried switching it ON, after POST beep, it turned off again.

When I checked inside the cabinet, the Processor fan was not spinning.. so the BIOS setting automatically shuts down, because processor is overheating.

I tried connecting the fan to another system fan header in the mother board, it was spinning. Now I am running the processor fan, from the system fan header which has only 3 pins, so the fan runs at full speed always.

Is it ok to run the processor fan from system fan header 3 pin, while the fan has 4 pin cable. Is there any risk ?

If not should I change the motherboard or motherboard & processor, please guide me what should I do. In case I have to change the hardware my budget is 10 to 12K ?

Below is my current configuration:

In answer to your 1st question, running the CPU fan off a sys fan header by itself is not a risk. As you yourself have mentioned the only thing is it will run at full speed all the time and thus be a little noisier.

However, since some portion of your motherboard has failed, there is no guarantee that other part(s) may not fail in future. Safest option would be to change mobo+cpu.

In the end its' the user's choice

Alright, seriously do you think with your a*s? OP is asking if it's okay running cpu fan that way and if he should change hardware because of faulty fan header. He is not asking for suggestions on new purchase specifically. Read the post carefully and post accordingly, not blindly. Post count won't help in your life. ^ 999999

> Its completely fine running a 4 pin fan on a 3 pin header. As you said, it will always run at full speed.

> You can control the fan speed using software such as Open Hardware Monitor or even from the BIOS. There should be a setting similar to "associate fan to" or "use temperature for this fan". Set that to CPU and it will be controlled according to CPU temperature.

> There is no harm in running CPU fan at full speed. I do that all the time during summers.

> No need to purchase new hardware. It's fine.
