i have a pc from HP its model is HP pavilion 580-101nv i have it for 3 years and the only thing i changed in it is the psu with a cooler master mwe 500 white v2.I already thinked that it will help my gpu making it cooler but i did not see any difference at temps my gpu reaches 82c max for now and in summer reaches 85c max.I tryed to clean the fan and replace the thermal paste but i dint see any difference too and im not sure if i placed the thermal paste right.btw when i oppened the gpu to change thermal paste i saw some stickers that im not sure what are those but they was came off on the upside of the cooler and not on vram or whatever it is needed for those stickers.I dont think too that my case has bad airflow my cpu is at very good temps without replaced any thermal paste on those 3 years its temp 26c when im browsing or watching videos on youtube with overclocked at 3.4ghz and when gaming it max at 36c.The gpu fan is running at 2500PRM when gaming but only when i play rocker league the fan helps the temperature to drop from 80c to 65,on other games call of duty,ark survival evolved,fortnite it doesnt help.I rember at summer that it was 36c inside of my room the gpu reached 3700PRM when i was playing ark and the temperatures was 83c.
