Should I Use Static Pressure Fans in This Setup?

[InfiniteXero]

I have a NZXT S340 case and I'm planning on getting a Phanteks PH-TC14PE cpu cooler. As can be seen in the photo below, the cooler in this case will be very large and take up a lot of space:

Considering that, I was wondering if I should use static pressure fans for the rear and top exhaust or stick to regular airflow fans?

Yes if you are running a overclock build.

 

Would actually help quite abit from the standard fans.

Use Static pressure fans for CPU coolers.

 

Use Air pressure fans for case fans.

 

Simple.

For case fans, I wouldn't bother swapping them out. At the end of the day, chances are that your temps wouldn't change at all going from one fan to the other. The only time that I would bother actually changing out the fans is for radiators, thick cpu coolers, or to go through packed drive cages. If you didn't already have the fans, then I would say go for it if you like, but don't expect any real temperature differences.

Considering the density of the case with the cpu cooler, are the static fans still not worth it?

There aren't many obstructions to the airflow in those positions, so airflow-optimized fans should be fine.

Best answer in the thread. 10/10.

You don't want to use static fans for anything else but having it against a radiator. Airflow fans will work perfectly in your setup as case fans  and static fans for the CPU.

Or always use static pressure because odds are that your up against a filter, grille, or just operating against back pressure. Static pressure fans work well in all situations. Airflow fans work very well only in open airflow and blow in other situations... I choose static because of its flexibility.

With no pressure difference airflow will out perform pressure in most cases. As pressure rises performance of both static and airflow drop. BUT airflow performance drops off much quicker for airflow then pressure. The only time there will not be a pressure drop is if the fan is doing nothing.

I also have the s340 and am using 2x140 in the front and a 120 rear exhaust. I do not use the top and currently have a book sitting over the vent. By using pressure fans In the front I can positively pressure the case better, which allows me to not use the top fan.

BUT I also switched to noctua PPC fans that only go above 900rpm when gaming or rendering. I found the stock fan for the s340 loud, and also plan to add sound dampening to the internals and perminatly block off the top vent(my case sits on the floor, and I can see both cooler fan and rear case fan through the top, which means I can hear them as well).

Static pressure-optimized fans don't really "work well in all situations". They make more noise for a given airflow than airflow-optimized fans. In practice at max RPM you usually just get the same noise level, but with a lower airflow. Static pressure-optimized fans are thus no more flexible than airflow-optimized fans.

 

If you graph static pressure to airflow, you see one type of fan excel towards one end of the spectrum and the other type excel towards the other end of the spectrum.
