Hey all, Ryzen 1700 (which I've dropped back to stock while investigating this; around 1.1v - was 3.7Ghz all core OC with same voltage) on a B350 motherboard with a Corsair H100i V2 AIO cooler now mounted in the top of my case, which is approximately 2.5 years old (I was actually a replacement unit for the older H100 which I RMA'ed and they sent me this). I've noticed over the past month or so, that my load temps were getting really hot while encoding in Handbrake; ranging anywhere between 85-95c+ at which point it would shutdown to save itself. My idle temps used to be around 35c and load temps around 65c-75c which I was happy with. Over this past month or so I've moved my AIO from the front of my case (and had 2x120mm in the top of my case for VRM cooling) and swapped them around: AIO in the top, fans in the front. This seemed to do the trick and temps were back under control... ...Until I turn my PC on this morning and at idle it's around 50c-55c, and load is headed 90c+. I lightly tapped/knocked the top of my case, and therefore the radiator, and immediately my temps dropped back to an acceptable range. There is no knocking or sound coming from my AIO that I can hear. Is it a sign of air bubbles in the system? If so, can I do anything about it, or could I keep tapping it a few times to see if it clears by itself? Should I seriously think about replacing it? (I doubt I'd be covered for it as it was an RMA replacement unit). TIA

Can you give a bit of info as to what makes the board awful?
