Xtreme v3 one fan front to air in & one upside and back side for exhaust..Welcome to the forums, newcomer!
What is the make and model of your case? Number of fans in said case and their orioentation?
its summer in here so weather is hot..temp always above 38°C.. my room has good airflow.Then my casing front fan is aiming the card also..What sort of ambient room air temps do you have? As for your case, you might want to see if removing the front panel+aiming a fan at the case's front, to introduce ambient air to the build helps alleviate the temp issue.
As for your GPU, what thermal paste did you use to replace the one that came with the card? What did you use to remove the previous thermal paste?
