Bad fan header and broken case fan

Hey

Been tackling a really odd problem last few days.

I originally had x3 Silent Wings 3 case fans. 4-pin high speed jobbies.

Headers 2 and 3 are for the front two fans, and randomly Header 3 fan (the bottom front) started making high pitched capacitor like electrical whine noises. Then the motherboard and windows fan software would have hard time reading correct RPM. Sometimes reporting 60,000rpm. Imagine! haha. Then the fan wouldn't register any rpm below like 50% rate. And eventually it just wouldn't spin. It would try and wobble a little bit but wouldn't get going.

So I replaced all the fans with the newer Silent Wings 4, thinking, the fan was just on the way out.

I've had the same issue happen again in the last few days! So knowing the fan is new, I moved it from Header 3 to Header 4 (thankfully both easily accessible at the bottom of the board). Same issue. Today I received my fan splitter cable and I thought perhaps both fan headers were iffy (being right next to each other on the board perhaps something linked between them... who knows). So I used the known good Header from the fan above and nope, fan is goosed. It just tries to spin but can't.

Now I had thought the Silent Wings 3 fan was just old - perhaps it wasn't. And I know the Silent Wings 4 fan is new. Can a header on the board pop a fan?

I'm going to try and replace the fan and only use it on the splitter cable first of all, and not touch the "cursed" Header 3, see what happens. Whole thing has me confused somewhat.
:confused:
 
I should mention I have reached out to Be Quiet for a replacement, but I've never come across something like this before.
 
Well I've been on to BeQuiet over the last week and they have been great. Sent me out a replacement which came today. What is not so great is they sent me just a fan. Not a retail or a boxed like for like unit. I've chucked my old box, accessories and fan away (they asked me to break the fan and send them a picture). I have no way of mounting the new fan, which is disappointing. Currently held in place with cable ties. Good news is, with the splitter from the fan above it, it is working absolutely fine! I'm not even going to entertain trying it back in Header 3 on the board.
