got 5 fans in case, stock GPU fan, and COOLER MASTER Hyper 212 Plus on my CPU

My card idles around 45 and went up to 98 in my last gaming session which only lasted 20 minutes. I already reapplied thermal paste but it didnt change anything.

did you blow through the exhaust port on the back of the card to expel any dust globs which might be blocking the air from cooling the card ? or take the cover off to see if there was any dust ? and if you upgraded the drivers and this started happening, go into the device manager and roll them back. Sometimes new drivers will make older cards work too hard.

and is the fan working ?..... the one on the card.

yea the fan is working, I have to keep it at 100% it at even keep it this cool. Didnt try blowing out the back end, doubt that will do much. its been running hot for awhile.

Reminds me of all those times where I repaired/cleaned people's PCs that had never been cleaned before and had 1-2mm of dust piled up on the CPU heatsink, completely obstructing the space between fins and sometimes even preventing the fan from turning altogether.

A simple way to avoid that is to build a case around positive-pressure airflow with filtered intake fans... keeps 90-95% of the dust out of the case for much longer operation between thorough clean-ups.
