Im not 100% sure the exact model but its an NZXT AIO and its standing vertically at the front of the case with the tubes coming from the top, if that makes sense? its also a few years old as its a preowned PC from a family friend
My mums computer has been running horribly slow recently, i checked over it and found out the CPU is running at 100 degrees idle. She said she heard a gurgling type sound the other day, wondering if its maybe the aio is having issues which could be causing the massive change in temps and in turn...
