I'm hoping to find other hacks for it. also I cannot find the stock firmware to go back yet, but im sure someone archived it as coolermaster pulled it down **Q: Does this support the front fans of the TD-500 case?** A: No. the TD500 has RGB fans. This controller is for ARGB devices. CM-PNguyen **Q: I have msi b450 tomahawk max in a cooler master mb530p with 6 sikleflow argb fans. can i connect all 6 fans to this controller and then to the mb?** A: It’s possible with a 1 to 6 splitter to get them working. But to control them Only if your motherboard has an aRGB header then you can use the software. If not you only get the basic options **Q: If my asus motherboard doesnt have 3 pin 5v argb. can i use the serial ush cable to controll the argb from asus aura or asus armory crate??** A: Sorry when you said ush, I assume USB right? Well, I have the same problem, and connected via USB, my computer detect the hardware but not aura or armoury, so... no you can’t ## Frequently Bought Together - Cooler Master Co., Ltd Mfx-Acbn-Nnunn-R1 Argb Small Led Small Controller For Fans And Coolers 6 Preset Modes Thermal Detection Mode - ARCTIC MX-4 (incl.
