I recently installed three exhaust fans at the top of my PC case but noticed they're actually blowing air into the case instead of out. I've compared them to my rear exhaust fan, and they seem to have the same orientation. After a long day at school, I came home and realized this was happening. All the fans are concave, yet they're blowing air in. Am I just overthinking this?

It's possible that you have some fans that are designed to blow air in instead of out. Some models have a 'pretty' side that faces out, but they might actually be reverse fans. If your temperatures are fine and there's no dust buildup, it shouldn't be a huge issue. Just keep an eye on it!
If you're doubting whether they're working correctly, try using a piece of paper to test the airflow. Just hold it near the fans and see which way it moves. I've done that before—it’s a quick sanity check!
Check for the arrows on the fans themselves—they should indicate the direction of airflow. It’s a pretty handy feature that could clear up any confusion.
That's good to know! I thought I totally messed up the installation.
