Phanteks Eclipse P400 Airflow Advice

[ClassicalPotato]

So I recently ordered a decently high end gaming computer (specs below), and after receiving the Phanteks case, I found out that it only had two fans. I haven't assembled the computer yet but I can already tell that airflow will be a problem.

Now, I'm considering putting two 140mm intake fans on the top, and two extra 120mm intakes on the front. Will this cause problems with the single 120mm exhaust fan? If so, is there any better ways to deal with the airflow problems? Any advice is good advice, and I'm open to pretty much anything short of cutting a hole in the front of the case (Though that probably would help). Thanks in advance!

Welcome to the Forums!

 

I would recommend to balance the intake and exhaust with either two intakes and two exhaust or to go with three intakes two exhaust to promote positive air pressure if you want to help minimize the amount of dust entering the case. That can also be done by varying the RPM of the fans and therefore the intake volume.

Generally what I do is 2 good 140s (Noctua NF-A14 iPPC or Corsair ML) in the front and a single 120 in the back. I'd do something like https://linustechtips.com/main/topic/876464-modding-noob-making-p400s-front-panel-more-airflowish/ though to get enough air in

Lack of fans isn't issue. That case has practically no way for air to get in from front. Only holes are under front panel. The newer generation is so much better with both sides of front panel being mesh.

It does actually also have vents at the top as well (similar to the S340)

I would put two 140's at the front and a single 120mm at the back, and see if the temps are fine (the 1600 should be, the 1070 might be a tad warm) If you're okay with the temps you get, Great! If you're still unhappy with how warm the system runs, Consider an extra exhaust top fan directly above the CPU cooler, or possibly look into Front panel modding (though with a system like that, it's probably not needed) The Blue Build in my signature uses an S340 (functionally identical case) with 4 fans and runs relatively cool (nothing above 70ºc)

I've actually decided to do exactly that. I've ordered 2 140s for the front, and I'm going to move the stock front fan to the top for extra exhaust.

There should already be two fans in the rear and top exhaust  They dont put the second fan in the front. Same with the H500
