Ive noticed the past few days that my EX4 is running in the high 150-170 F range. The unit is vented properly and in an open area, and while I have not gotten any heat warning I was just wondering how other users might cool their unit for safe usage. I know with summer quickly approaching the room that the server is stored in can easily hit 80-90 degrees during the day which calls into question if there would be issues

The operating temperature of the EX4 should be between 32° F to 95° F. You can try running a system test to check the health of the unit. Check page 131 of the manual.
