200mm fan vs 2 140mm fans!?!?

[grav varma]

going to buy the phanteks enthoo pro, which comes with a 200mm fan in the front as intake. i am just wondering would it be better to replace this fan with 2 140mm fans from noctua, or just leave in the 200mm. i also plan on installing a 120mm fan inside on the drive cage which is infront of the 200mm fan intake

2x 140mm will be better than a single 200mm. a 200mm fan is best for unrestricted airflow. Once you place a fan filter and/or case mesh in front of a 200mm intake fan it dramatically decreases the air flow. Also 2x 140 will focus the air more better than a single 200mm

I've experienced this with the HAF 912 Advanced CM Megaflo fans and found 2x smaller fans pushed more air through the drive cages than a single larger fan that pushed all the air around the drive cages and towards the side panels. But for exhaust a 200mm fan is better than 2 smaller fans for the sake of positive case pressure, surface area, and less noise.

A 200mm fan has more area (2 140mm~30787.6², 1 200mm~31415.9²), so if the 200mm fan is a decent pressure optimized fan, I say save your money on the 2 140mm Noctuas, and just add a good 120mm (pressure optimized) behind the drive cage.

*note That is a good looking case, I might just get one.

but the thing is is that the 200mm is ths stock included fan, and i don't know if it is good enough or needs to be replaced
🙁

That is why I said IF it was a decent fan. I've had cases that came with fairly good fans, and some with fans that looked like they came off of a 1995 Gateway.

There aren't any good 200mm fans out there that can be use for intake. Only exhaust. Its best to use 2x 140mm static pressure fans for intake.

Me, I would suggest you not to waste money substituting the fans, but if you want, you could buy another fan for the top or bottom (wherever your case supports it) I think you will be ok with these 2 too for now, but you can always buy more fans
