After a hard day of job, i've connect my self and just noticed suddently i was Perma Ban for Third party app.
Unfornatly i never used one, BUT i have few game who take RGB Fusion from Gigabyte (for changing my motherboard RGB led) as a Third party.
I wish have an explanation because i found it special.
Best greeting 
Uh...no. Software that controls the LEDs on your motherboard is not going to count for Riot as third-party game-altering software.
By that token, Spotify, Microsoft Office, Discord, and Minecraft would also third-party software that will result in a ban.
If what you're saying is true, then submit a support ticket to them and ask them why you got banned.
I would also suggest checking your match history, make sure your account hasn't been compromised.

Why do most of the guys that complain about this have the same broken English? And this is across all games, not just League. Certain regions are notorious for cheating, connect to regions no where near their own. You learn a lot of this from playing Korean-style grinder RPGs, I have 8 some odd years of experience.
Sorry bro, but you just need to change your habits. An RGB program is highly unlikely to trigger even the most aggressive anti-cheats lol. Unless the anti-cheat hooks into your kernel, you didn't get banned for using motherboard software lmfao. Anti-cheats only care about what interacted with the client, and will often run a check of your running applications for known software. some popular programs are very easy to detect and most anti cheats will hunt them down specifically.
Anti cheats are like virus scanners lmfao, they look for for shitty behavior.
