Or ask for a replacement controller. Worked for me. I also send my bug log to the support and eventualy right before new year they made 2.5 that seems to work. Also if you have more than one controller or other units connected to ur 4 pins molex plugin cable then dont connect more then 1 box pr power cable. This also seems to work. Im still testing but i was given this advise from support. So now i have 2 boxes with each ther own 4 pin power cable and nothing else. Or 1.4.4 version also works.

r/thermaltake on Reddit: TT RGB PLUS CONTROLLER NOT RECOGNIZED?
January 23, 2022 -

For all of you out there who might have issues with the TT RGB Plus software not recognizing your controller (Especially you with an AMD CPU)

Here is a link for the 1.3 version of the software https://file.thermaltake.com/file/software/TTRGBPlus_Setup_133_x64.zip

This is one of the most stable versions, according to reddit.

Once you download it, make sure you disable automatic updates

Unplug your controller from the PSU molex connector (FROM THE CONTROLLER'S END) while the software is open, then plug it back in, it should recognize it now.

Then go to Task Scheduler (search it on the Windows search bar on your task bar) Find the task associated with the software (most likely named TT RGB Plus) and disable it by right clicking and selecting "disable"

Hopefully this will help you all.

Stay positive and faithful to the PC Master Race!

If not, attempt to use a standard MicroUSB to Type-A USB and connect it through a regular USB port and see if the controller is detected. If all else fails, contact Thermaltake Support for further troubleshooting.

r/thermaltake on Reddit: TT RGB Controllers not Detected in TT RGB Plus
March 24, 2022 -

Hey, I recently rebuilt my PC and added a couple more TT RGB Plus products to my case in the process.

My case has had 5 Riing Plus RGB fans plugged into the 5 port controller that comes with this 3 pack: https://www.thermaltake.com/riing-plus-12-rgb-radiator-fan-tt-premium-edition-3-fan-pack.html

I also have upgraded my RGB fittings from the original non addressable version to the Plus version: https://www.thermaltake.com/pacific-rgb-plus-tt-premium-edition-g1-4-petg-tube-16mm-od-12mm-id-fitting-6-pack-fittings.html

I have also switched to this CPU cooler, which has no issues being detected in TT RGB Plus software 2.0.5: https://www.thermaltake.com/pacific-mx2-ultra-cpu-waterblock.html

For reference I had no issues with TT RGB Plus 1.0 software and my 5 Riing Plus Fans + the OG Pacific RGB fittings for years. Once I rebuilt my PC and added the above TT products, I started having these issues.

The first time I turned on my PC after rebuilding, I booted up TT RGB Plus 2.0.5. I saw my original 5 fan controller but not the new controller for the fittings (plus an additional Riing Plus fan I had). I tried rearranging how the controllers were connected and ever since that first boot I cannot detect ANY of my controllers. I have read the past posts here about this and tried only connecting one of the controllers, having only 1 controller per Molex rail, disconnecting and reconnecting everything.

Here is how I have it connected to my PC currently:

USB Header -> Pacific MX2 Ultra CPU block & RGB Plus Fitting Controller
USB Header -> 5 port RGB Controller

I have tried the daisy chain connector, with the micro usb end plugged into the 5 port controller. It seems that the older controller doesn't have the port for this newer cable to be connected the other way around. I am open to any suggestions here, I would hate to have half my RGB not even on. I know many of you are unfortunately very knowledgeable when it comes to dealing with TT RGB Plus software issues, and your help much appreciated. Please ask if you need pictures or more information. Thanks!

Hey guys!

Im new to watercooling, but I still went ahead and managed to complete my loop. However, when I opened my TT RGB plus I got the error: ''Can not detect controller, please check the Fan Controller is connected. (Error Code:H_0x0001).

Im not sure what it means, and how to fix it. I was also unable to sync it with my Razer Synapse.
My motherboard is MSI Tomahawk B450 MAX.

Any bit helps. Thanks a lot!

November 5, 2018 - Though, here are few fixes you can try to get your controller recognized by TT software, link: https://community.thermaltake.com/index.php?/topic/64522-controller-not-detected-error/ Also, since you bought your fans from 3rd party, there's no telling if the fans themselves are good without issues.

July 13, 2020 -

All connection have been rechecked and triple checked

Controller Cable is connected on motherboard USB 2.0 tried both pin connections on board

Dips are in default for one controller

Lights do have power and are in a rainbow affect

System Specs

Windows 10 Pro 64-bit

AMD Ryzen 7 2700x

MSI MPG X570 Gaming Plus

Please do not recommend MoshiMoshi0 It does not find the Port Identifier and I'm not a coder. If there was a full format then I might be able to use it but its done in bits and pieces I'll admit it's confusing. A working Gui would be better.

I was thinking about buy the MSI MAX ARGB any thoughts? Would it work in place of the TT controller?

In case there is a representative from Thermatake I woke up to no RGB lighting but fans still spinning. Removed and reconnect Molex cable and tried different Molex connections on PSU and still no RGB just fan spinning. The kit is a Riing Plus 12

Update: after two replacement hubs from TT they now work.
