I'd go with an H60 plus a second fan, corsair ml120 pros for the radiator. At 100c you're being thermally throttled.
Hello, I just received my new Aurora R11 yesterday and I'm having serious CPU overheat and fan noise issue, is this normal?  The idle temperature for CPU is around 60°C and it jumps to over 90°C, occasionally hitting 100°C while gaming, and the fan noise can be heard from another room. The GPU is 35°C idling and 65°C gaming so I think it's okay.  I checked inside the case and the CPU only has a air cooling fan. Can it be upgraded to liquid cooling?
