It didn't come with any fans other than what the PSU had, which doesn't count. Only other fan was the processor fan, which doesn't count either. I installed a 120mm ~96 cfm fan which makes 45decibals of noise at the back of the case, but my CPU is still going at 50*C-55*C. The system is low 30s*C and the PWR or w/e is high 30s/low 40s.
