Hey guys,

I have a Silverstone Fortress case that has 3 case fans, 120mm and twin 180mm fans. A few weeks ago my front 180mm fan stopped working correctly, it still span but instead of spinning at 700rpm it was sitting between 200-300.

I ordered a replacement from OCUK and popped it in and the same problem.

Ok so if i plug the new fan (or old) into another fan socket on my motherboard (gigabyte skt1366 UD5) they work perfectly well.

If i plug a smaller fan like my noctua 120mm into the "broken" socket it will work.

Does anyone have an explanation for this? The fan was plugged into that socket for 4 years and always worked fine. Now it seems to be putting out less voltage for some reason.
 
Going to give this a single bump as I'm still having trouble with this.

I was thinking i could maybe get some sort of PSU > multiple fan connections adapter of sorts, was wondering if they actually exist?

But my main worry is maybe my board is starting to fail?
