Or rather, the temperature seems to fluctuate far more dramatically. My i5 will idle at around 50C (curse you Haswell) but will only peak off at about 70 under load. On the other hand, my R9 280X equipped with a Corsair H55 will idle at around 40C but can max at 82C at full load. I've had similar experience with previous high end cards. What happened to the days of passively cooled graphics?
