after looking at a pic of this computer on the net, it is more likely a problem of too hot of case temps than of inefficient CPU cooling. It appears that there is only the PSU fan exiting out all the hot air made by the hard drive, CPU, and graphics card. I see there is an 80mm fan opening on the back of the case to add another exhaust fan. I suggest you add one. Finally, adding a 120mm side fan on the mesh side opening will further improve case temps, but may actually hinder smooth airflow inside the case, which can cause some issues with hard drive cooling, as less air would likely get sucked in from the front of the case now that you'd be pushing in air from the side.
