Building a new PC

I believe GamersNexus did a video on fan locations and they found that if they had an exhaust fan before the CPU fan it actually increased temps because the exhaust fan is stealing air from the CPU. Might want to keep an eye on that.

Only if you have negative air pressure in the case. Which he would not. Just maintain more intake fans than exhaust fans, and it's not a problem.

Every case is different. But with air cooled CPUs, airflow is incredibly important. With my recent upgrade, I prioritized this. Using the same case, I reduced my temps by ~20+ degrees, just using better quality fans and smarter air flow. While using a CPU with noticeably more power draw that's overclocked to 5.4.

You are welcome to take it up with GamersNexus. I'll side with the former Dell engineer that now runs his own company and has infinitely more resources than I do to test bench thousands of products.

I watched the video. He's right that in the wrong configuration, too many fans can be detrimental. But only if you install them in a reeruned configuration that results in negative air pressure. Which lots of idiots do.

More fans in proper configuration will give you more airflow and cooler temps though. The only reason it wouldn't is messing up the airflow directions. Clay's CPU/GPU are producing 150W/300W+ alone. That produces a lot of heat that needs moved. More fans move more heat. The newest hardware is super power hungry. If you want to push performance, you can't skimp on fans and you have to be smart on placement.

I guess you specifically missed the part where he talked about if you wanted to install 3 intake fans and 3 top exhaust fans that the exhaust fans towards the front of the case will pull air directly out before reaching the CPU and that he recommends installing fans behind the CPU cooler.

So is he right or wrong? Because that's not a negative pressure configuration like you are claiming.

I guess I'm not understanding where you get your belief that a fan infront of another fan is or isn't going to be taking air out of a certain area of the case based on negative, balanced, or positive pressure.

He's right. You should not have exhaust fans at the front of the case. That's an example of a bad airflow setup. The frontmost top fan should be intake in that config. Which would give you more intake fans than exhaust. Which provides positive air pressure that you want.

That doesn't mean more fans are bad for airflow. That simply means 6 fans in the wrong config can be bad for airflow.

So then your first reply to my comment where I tell Clay to look out for that is what exactly?

Because now you are saying the opposite. Before it was not a problem. Now its the fan should be intake.
