MSI 890FXA-GD70 faulty fan header?

[reflex]

Hi all,

So in a previous thread I posted here, it seemed my computer would not work properly in the mornings.

This morning I turned my PC on and received a BSOD while trying to get into windows.
I restarted and went into the bios and noticed my CPU temp was 105degrees C.
I switched off immediately and checked the pump wire for my H50.
All was in order there, it is plugged into one of the non-controllable fan headers on my mobo. SysFan 3 I think it is.

I turned the PC back on and monitored temps in the bios and all was fine.
Now it's either a faulty pump, although Ive googled this a bit and a couple people have had similar problems and they just plugged it directly into the supply.
Or its the header.
I am going to check with just a normal fan later today or tomorrow morning.
What do you guys think, sound likely or not?
It's probably what has been causing my issues in the morning though...

Unfortunately I already had the smell of burnt electronics, but it still seems to be functioning...
