[SOLVED] motherboard cpu cooler pins broke, can i fix them easily or change the assignment?

[Jesse.m.niemi]

a month ago my computers cpu fan connector broke and wouldn't let me start the pc if anything was plugged in it. i've fixed it by changing the connector to a case fan instead of cpu fan connector but it keeps booting me to bios because i dont have anything connected to the cpu fan connector. is it possible to make it so my case fan was the cpu fan?

Depends on motherboard. Some allow this, some don't.

I have a asus prime b450-plus.

That's a pity. Since ASUS does not publish their BIOS manuals on website unfortunately I cannot check whether this one is capable of doing so.

A motherboard will not start unless it can detect that a cpu cooler is installed and working.
It does so by sensing that the cpu cooler fan is turning at perhaps 500rpm.
I looked, but your motherboard does not seem to have a pump fan which also would work.

Can you supply a photo of the damaged header?
If you could just connect the speed sensing lead from another fan, that might do it.

I'm pretty sure all of them just warn you on boot up that the CPU fan isn't being detected and whether or not you want to keep booting. And of course, you can set this to be ignored in the firmware options.

Otherwise passively cooled computers wouldn't work.

SpeedFan has the capability to change addressing, so any fan header can be used as the cpu fan header. It just takes some above average learning curve digging into the 2x fan tabs to get to that point.

Could you help me in changing the addressing?
If not is there a tutorial or something that i can use to change it?

There are tutorials around, it's just a matter of pointing a certain header to respond to cpu temps, you don't have to actually put in the address, just the header. You'll need to figure out what header is what, on which bus etc.
