Nope the palit cards just have very good cooling, and these figures are from early april.
GTA5 is in windowed mode at 1200p. 4x msaa (with MFAA so actually 2x msaa processing cost), natural vision mod, advanced graphics options disabled or set to min, fxaa off, shadowns etc. either 1 or 2 settings below max. grass on bottom but one setting.
GPU temp averages about 45-48C, it can hit 50s tho if thundery weather.
If I play very light games like FF10, which is really light on the GPU but still activates 3D load, the temps dont even get out the 30s.
Obviously in june/july/august the story would be different.
Seems OP fixed now anyway, so yeah dont set the global setting to full power, just set full power as and when needed on a per game basis on the game profile.
Also forgot to mention I do have a modified fan profile.
Fan doesnt stop on idle, it runs at 20%, I change fan profile from stepped to progressive, meaning in general it reduces temps.
Also when I used to play GTA5 at 30fps, the gpu temps were even lower.
Remember I havent jumped on the 144hz bandwagon, so my FPS is capped.
