Zotac 5090 Arcticstorm

[Mr Mcgoo]

So i friend of mine stupidly bit the bullet and got himself a used Zotac 5090 Arcticstorm for £1600 due to the pump in the aio having died. Zotac supposedly refused warranty but confirmed the card works fine. So for safety we did a very quick test and the aio seems fine but it's getting to 80c under load which is bad as i have not seen above 45c at 100% on my 5090 arcticstorm. Either way that's good for him as he is planning on going for a custom loop anyway and is taking my old kit off me. We don't want to remove the aio just yet until we check to see if anyone here knows what pcb it is so we can find the right block. Hope to find the answer here instead of contacting a few places/manufactures to find the right block. Anyone have any idea? Thanks in advance
