Where did i suggest getting a new board? I said
could have. I wanted to demonstrate that while 15 euros may not be much, given the base price of the board is it worth to invest in it? Because given his post with the CPUs temp it may not be needed. Plus he got the board only 2 days ago so he could substitute it. Finally given that its the same chipset there would be no need to re install drivers (maybe audio / lan) but no need for clean install. Again I am not saying he should do this but the possibility is there.
Yes because a 8+2 phase motherboard with a 8 core CPU cooled with H100i is totally comparable to his situation
Edit: and so this post is not totally useless to OP. Look into ram coolers. Something like this
I found a cheap ram cooler locally (like 4 euros on sale) and it a perfect fit for the vrms and made a noticeable change for the vrm temp under load
