So this is an old post, but im looking for some info on this. I just bought one to replace the h97m-e i was running and apparently the 4 pin headers arent really 4 pin?? the speed isnt an issue, its that im running 4 pin LED fans and when they spin slow, the LED's dim, and fast makes them bright. Is there a work around for this? I dont wanna run a fan controller but i may have to.
