Hi RDT, My experiences so far: The problem is kind of “fixed” for me. After having the fans running for hours suffering the blinking effect, it suddenly stabilized. At first I kept getting it after boots for short times, but nowadays they work fine from the start. Dunno if that will be the same case for you, but just having the lights running for hours fixed it for me. About the system treating the fans as a single block, the same happens to me when I configure the system as rainbow in the AURA app. When that happens I just hit the default button, or enable and disable aura from BIOS, and it works fine again. I know, messy... but works =P Hope that helps.

Yes, and they work with no issues. Nope, both 12V RGB headers and addr 5V RGB header are working fine with any device other than the controller =( Yes, all testing has been done with static mode lightning, and that's where the flicker is more evident. Included controllers with the fan packs are working fine, if that's what you mean. My only problem comes with the Sync controller when fan are set to PWM mode in the BIOS. I understand lightning and speed go through different channels, but in this case something weird os obviously happening =( Funny thing is, as long as I have ONE “fan speed” channel in PWM mode, ALL channels lightning fails. It's not a per-channel issue. As long as the TT Sync controller gets a single PWM signal on any channel, from ANY source (I have tried many, not just the MoBo), ALL channels lightning becomes a mess. I guess that's not managed directly by thermaltake, right? =P Because I couldn't find any local seller (in Spain) and ended up buying it from ebay (overseas) from a provider its name I can't even remember T_T (which is gonna be a real pain to manage =P). Ok, thanks anyway... I guess I'll switch to the regular fans controller included in my packs and go with static lightning or something.

Might be resurrecting an old thread, but I'm experiencing the exact same thing with a Maximus X Hero. When fans are set to PWM in the BIOS, there's random flickering and blinking on fan leds, which makes it really annoying. Transitions don't work fluidly either, because of the random blinking. Change the headers to DC in the BIOS, and then lightning works wonders. A real pain, since switching headers to DC mode turns my PC into a plane about to take off =( So I have to chose between high noise levels, or annoying lightning. Any ideas? =( Fans are connected to CPU_FAN, CPU_OPT and CHA1_FAN btw. Oh, and probably worth mentioning, I think there might be something weird with PWM signals, since I had one of the controller channels connected to my GPU (just a regular PWM header, since one of the rads is there for GPU purposes) and that had the exact same effect. At the beginning I blamed the GPU header for whatever reason, and moved on using a different approach, but seeing this makes me wonder, why do I get distorted lightning whenever I input a PWM signal to the TT Sync controller, from whatever source, be it MoBo or GPU? Thanks in advance!
