You need to give PC more space, if its got intake fans on its right hand side it helps if its got more than a little gap between it and wall. especially if you put AIO on side facing wall.
I don't find any reviews from places I know, or trust. That probably tells me all I need to know.
wonder what GN doing with their fan tester... but I digress.
They aren't Noctua, thats for sure.
Yeah, there's about 5 feet between the wall and the side of the PC.
