Unit was thoroughly tested with Furmark to ensure proper operation.  There are no issues.  THIS HAS A BLOWER STYLE FAN, which exhausts our the rear of the PC, so please make sure you know what that is before you purchase.  Also, blower style graphics cards can run a little hotter under very heavy workload.  Again, was tested at maximum settings with Furmark, and there were no issues.
