All 3 of my fans have stopped spinning in my Corsair 650D case?

So they just stopped spinning.. The fan controller does nothing and I've opened it up, everything is connected, etc. I've also heard that Corsair's fans are bad and the fan controller on the 650D case is very poor.

Currently, the three fans connect into three wires of the fan controller. The fan controller is powered by a 4-pin molex, so if the fan controller is broken, the fans can't get power any other way.

People have suggested connecting the fans to the motherboard, but I only see "CHA_FAN1" on my P8H67 motherboard?

Is there an adapter that fits into the 4-pin molex and has, say 4 or 5 small connections on the other end for my fans to connect into? So the fans run directly off the PSU (at max speed). At the moment, my Coolermaster GX650 PSU doesn't have any connections small enough for fans to attach to, hence why I thought there may be an adapter I can buy?

I'm brief in the PC building area, but my knowledge of fans is very limited.

Common fault on the Corsair 650D. The fan controller is broken and you should contact corsair for a free replacement. I had the same issue except the low and medium settings would not spin the fans, but the high setting would.

Assuming you're running an air/fan cooled heatsink, you could just plug in the heatsink fan to the one available fan header and make do with that until you receive the replacement.

Yes you can get a 4pin molex to branch into 3 or 4 fan adapters.

Your motherboard should also have 2 fan headers that I can see from quickly looking at a picture.

Unfortunately, I don't have an aftermarket cooler/heatsink if that is what you mean. Again, I apologise for my lack of knowledge!

Thanks for that link to the connector, exactly what I am looking for. It'll mean that my fans will be max speed all the time, but this is how I have it anyway.

I will definitely get that ordered, but considering some new fans in case the fans may have gone too.. I could test by putting a fan into "CHA_FAN1" (btw there's no FAN2 on my motherboard, only other is CPU_FAN or something)

EDIT: I should probably correct myself, my motherboard is a P8H67-M, instead of just a P8H67.

Ah okay, have just found the right picture of your motherboard and could only find the CPU_FAN and CHA_FAN1 as you said

I think your fans would be fine, but no harm in testing them!
