Hey everyone! I'm trying to figure out the best fan configuration for my PC. I was thinking about adding three fans at the top of the case, but I'm concerned. If the two fans closest to the front are exhausting air, won't they be pulling away the cold air that's meant for my CPU cooler? I want to make sure my setup is efficient, but I'm not sure how to position my fans. Any insights?

You make a good point! Although some people still prefer aesthetics and pack all fans as exhaust on top, doing so might not be the best for cooling performance. If you have enough fans, it can still work fine, but I’d suggest mixing some intakes with your exhaust to optimize airflow. Check out Noctua's airflow guide; it has some solid recommendations on this.
Totally see your concern! I recently watched a video that really emphasized this. It showed how having three exhaust fans on top can mess with the airflow for your CPU cooler. It’s generally better to have the front-most top fan as intake to improve cooling efficiency. There's a good discussion about it in the video if you're interested!
I think you’d actually be better off having an intake fan at the top right alongside your air cooler, rather than a full exhaust setup. One exhaust at the back might be enough—sometimes that’s even preferable!
Yes, you're right! Having the top fans nearest to the front as exhaust could definitely disrupt the airflow intended for your CPU cooler. That's why many experts, including Noctua, recommend setting these fans as intakes instead. You can check out their airflow guide for more details!
Definitely! The video breaks it down nicely. The airflow around the CPU cooler is crucial, so using the top-front fan as an intake really helps.
