ok, i am doing gpu rendering with my 1080 zotac and i was getting temps up to 81 degrees c and now i unlinked the power and temp in msi and also bumped up the fan to 85 percent and i set max temp to 70 and i have temps i want now under 70 but i see there is a perfcap reading in gpuz which am not sure if i am limiting or slowing down the gpu when i do this, anyone can shed some ligth on this let me know, here are some screenshots of my setup while i am rendering
