RAIDMAX Orion Case Review @ OCC
 

The temperatures under load were rather impressive! Though the same can't be said for the idle temps, the temperatures were right in the middle of the large pack of cases – so in reality there's no complaint. The CPU and chipset load temperatures being so low are likely due to the three fans in the case. The CPU cooler gets the help from the rear 120mm fan as well as the top 120mm fan getting rid of heat. Overall it performed quite well.
