I have 3 x Gen 3 Radions, One of them was upgraded to Pro a few years back. I have had these running @60% for about 7 years. I have recently cleaned the fans and vents from the inside out and are working flawlessly at this time. Still running on my tank currently. I am switching to Radion 4 now. So these are for sale at $350 a piece. Or make me an offer for all 3. Will post pics tonight. Or text pics on request. Thank you.
