Bypassing stupid proprietary ASUS controller for Ryujin II Cooler?

Posted by theo6942069@reddit | buildapc | View on Reddit | 8 comments

Hello everyone, I recently bought 3 ROG STRIX Ryujin II coolers second hand to use in some upcoming builds. It was suspiciously low priced at €33 a pop so I made the purchase.

I knew it wouldn't come with the right mounting bracket so I bought this separately, but stupidly didn't do more research and only now after testing realized the pump fan is powered via micro-usb that needs to be connected to a controller to operate. So it's basically paperweight right now since my CPU reaches 95°C at idle without the fan spinning.

I don't have this controller and doubt I'll be able to find it at a resonable price, so thought up a workaround using multiple converters, connecting the male micro-usb connector to a 'female micro-usb to male USB-A converter' after which could connect this directly to the back of the motherboard or use a 'male USB-A to 9-pin internal USB coverter'.

Would this power the pump fan? If so would it always run at full speed or will I be able to modify/modulate the speed?

Thanks for any help or clarifications!
