That may be your problem. Is the cabinet open at the back? If not, cut a
hole in line with the case fan(s) to let them blow air out of thecabinet.
PCs are not inteded to be kept in an enclosed space, especially at
the back. All that heat needs to go somewhere and not get recycled back
into the case.
