Hi my pc sits horizontaly and is a pain to get the motherboard out off I am getting a aio Cooler and I have read that the backplate supports the motherboard but if mine is laying down would I need that extra support?
Ok thanks I was just seeing if I could be lazy thanks alot for respondingYes.
No matter what orientation, the cooler needs whatever backplate it comes with. That is a critical part of the clamping mechanism to hold it together.
