Hi guys, I have an Asus R9 280X DirectCU II TOP (R9280X-DC2T-3GD5). When I'm gaming, I set my GPU Clock to 1200MHz, GPU Voltage to 1230mV, and Memory Clock to 6460MHz. However, when I run GPU benchmarks or even play games (I'm using BF3 to test), temperatures in my GPU reach the high 70s, even the 80s. I am playing on a 1080p monitor with maxed settings (i.e. ultra in BF3). Is this normal, or should I clock down and reduce voltage? Btw, the ambient temperature where I'm living is kinda high, temps of high 20C and low 30C)
