## Questions & Answers

**Q: What software does this work with? it seems to have a micro usb connection that goes to the mb usb header. however, what software can control it?**
A: there is a hack using the h500m firmware https://www.coolermaster.com/catalog/cases/mid-tower/mastercase-h500m/#Downloads 
and the master plus software though I have to say the effects arent very good as there are no multicolor effects and you cannot customize any animated effects 
also since these havr 3 pin plugs you can hook up off brand ARGB fans even if they have their own controller as long as they support pass though.  but honestly the effects that came with my fans were more interesting.  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.

**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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great aRGB controller for computers without native aRGB headers.
*by E***C on October 20, 2020*

I got this controller to use in my old PC before selling it to add a bit of flash so it would be a more appealing sale. The controller worked perfectly, I did need to purchase a USB header to MicroUSB cable to hook the controller up to my motherboard to allow for software control of the controller so you dont have to open the case to change the aRGB settings, and I do wish that cable was included...but it doesnt take away from it working perfectly. The controller worked well without that cable, however I think it would be a pain to constantly open the case to change any aRGB settings, so I got the cable, which at first didnt work but I needed to do was a simple driver update for the controller and then it was discovered in windows immediately. This controller was used to control 3 aRGB fans...2 EK Vardar Evo as part of an EKAIO 240mm, and 1 CoolerMaster Sickleflow aRGB fan as rear exhaust. It worked great to control all of them.The coolermaster software is not great, but its certainly better to have that option then not. All in all, this helped me to sell my old PC at a price higher then expected, and the buyer was ECSTATIC with how it looked.

### ⭐⭐⭐⭐⭐ Works Perfectly! But there is a catch
*by G***3 on July 31, 2020*

I just want to start off by saying that this is a product intended for CoolerMaster Fans, however it does use universal ports (ARGB Gen 2 port to be exact)So at first I thought this product was a scam because it didn't work with my ASUS TUF motherboard even though it says it's supported. YOU MUST PLUG THE CONTROLLER TO THE COMPUTER WITH A MINI USB CABLE!! After you plug everything into the controller (Including SATA power), you just have to plug it in via USB once for about 1 minute for the drivers to install. After that, you don't have to plug it in again. since I didn't have a USB header, I just plugged it in with my side panel open and unplugged it when it was done.The controller does not come with a Mini USB cable, so if you don't already have one, you're going to need one if you want this to work with your motherboard

### ⭐⭐⭐⭐ Works with CM software but needs firmware update first
*by J***E on July 21, 2021*

If you're wondering if this product works with the Cooler Master Master+ software so you don't have to pay $60 for the more expensive one: it does work. However, you'll need a USB 2.0 (motherboard pinout) to Micro USB cable. This product does have a port for micro USB but it doesn't come with the cable. Fortunately I had a spare one on hand and was able to update the firmware and it was recognized after that, so I was able to use the software for my Cooler Master halos.I ended up returning this for a different brand where I can connect all my RGB stuff to it and control them that way. But just be warned, if yoh want to use this CM controller to control your RGB in the CM software, you'll need a USB to Micro for your motherboard to connect to this controller, so be sure to have one on hand or buy one with this purchase.
