80mm case fans (Amazon)
80mm case fans (Amazon)
These 80mm fans are a super easy airflow mod for the 7040, because there’s a perfect little gap between the drive bays where one can mount. I only got two screw holes lined up, but it sat solid, spun freely, and helped the case feel way less “office PC.”
