ASUS ROG Hyperion GR701 PC Gaming Case Review
Cooling Performance Â
Thermal performance is an essential factor for any PC case. Your system may look fantastic and seem silent from the outside, but all of that is for nought if your PC has the internal temperature of an oven. Your PC case needs enough airflow for your components to remain cool under load and to prevent any form of thermal throttling. For our test, we used the following hardware using fixed fan speeds (so that only the case and its included fans can influence thermal performance).
ASUS ROG Hyperion GR701
Intel i9-9700K @4.8GHz at 1.2V
ASUS ROG Strix Z370-F Gaming @ 100% Current Capacity/ LL lvl16
Cooler Master Hyper 212 Black Edition @ 9V via Fan Speed Reducer
Nvidia GTX 980 Reference @ 60% Fixed Fan Speed
Corsair LP Vengeance LP (Grey) @ 3200MHz
Corsair MP500 M.2 NVMe SSD
Corsair RM550X Power Supply

600 RPM
Thermally, ASUS’ ROG Hyperion is a solid performer, though it is clear to us that our standard case testing hardware configuration is not ideal for a case this large. The ROG Hyperion is not designed to be used with smaller graphics cards like our ageing GTX 980 or air-based heatsinks like our Hyper 212 Black Edition. This case is designed to be used with large graphics cards and with either a large all-in-one liquid cooler (like ASUS’ ROG Ryujin III) or a custom liquid cooling loop. Even so, the ROG Hyperion delivered us admirable results, sitting on the lower side of our thermal graphs, even at 600 RPM.
  
1000 RPM
Cranking fan speeds up to 1,000 RPM has seen both CPU and GPU thermals decrease notably, with CPU thermals seeing the largest drop. Again, the ROG Hyperion delivers us respectable results, but the more open nature of this large chassis is not ideal for cooling a blower-style graphics card. Â
  
Max Fan RPM
Maxing our the ROG Hyperion’s fans at 1,350 RPM the ROG Hyperion sees another drop in overall thermals, but not a huge drop. Again, we will say that this case is designed for larger graphics cards and for CPUs that are cooled with a large AIO or a custom liquid cooling loop. That said, the Hyperion has not given us bad thermal results, and with the right hardware PC builders should have a better cooling experience.
