Motherboard's Chassis fan connectors not working

[Vendetta]

Good morning everyone,

I have a ASUSTeK COMPUTER INC. SABERTOOTH 990FX Rev. 1.01 and last night I finished transitioning all of my computer parts into my new SilverStone Raven 4 case with the CoolerMaster Hyper 212 EVO CPU cooler.

I went to plug in two air penetrator fan (SilverStone Technology Co., Ltd.INTRODUCTION：AP181=) and when I went to change the speed on the fans (like an on off swtich), I heard a big ZAP sound and my computer restarted.

I finally found the problem with the wires being put in backwards (not by me). However, the chassis fan connectors on the motherboard is no longer powering the fans and my BIOS no longer detects the fans connected to it for monitoring (but computer is still working fine), so I'm having to run an adaptor direct to my power supply for the fans to work.

Is there any way to fix this problem or is the chassis fan connectors toast now and nothing I can do about it?


Thanks!

Well, usually a big zap sound and a restart signify that something went seriously wrong. I suspect that you've blown the regulators that provide power to the chassis fans. They are not field repairable, meaning that you can't fix them. I would suggest getting a commercial fan controller to look after your fans.

If this board is new, it doesn't hurt to talk with the seller.

The big zap sound came from the on/off switch of the big fans that is built into the case, but the power to the motherboard's chassis fan is definitely shot. The motherboard is not new, it's a version 1.01 of the ASUS Sabertooth MB.

Computer is still working perfectly fine, so I've decided just to get power direct from the PSU with adapters and not try to repair anything risking messing up more stuff.

Thanks!
