i got a XFX 7900 XTX merc310 the temps are great with a delta of 8-10 when under 300 watts the secound it goes over hotspot temp jumps to 90 and slowly climbs to 95 with fan speed ramping up to 50-60% with normal temp being around 65 but if the gpu is in less use for example 280 watts there is no such issues just wanna know if a repast might not be the answer as i find it odd that a diffrence of around 40 watts would make so much more heat
