Cooling Options
The Eclipse P400S case was designed with quiet operation and good air-flow in mind to keep all your high-end gaming hardware running cool and reliable. There are up to six different case fan mounting locations along with support for liquid cooling.
Air Cooling
The P400S comes with two Phanteks Phantoms fans preinstalled. One 120mm intake fan on the front panel and one 120mm exhaust fan on the back panel. Both fans are very quiet; but they do not move a lot of air. Additional fans can be added if you want more airflow.
(120mm front intake fan – included)
(120mm rear exhaust fan – included)
The following table lists the noise generated by the two included case fans while operating at the three different speeds selected using the built-in fan speed controller. Sound Pressure Levels were taken 3’ from the front of the enclosure. The ambient background noise level was approximately 26 dBA.
With both fans running at full speed the noise is barely noticeable and certainly not loud while providing baseline airflow through the case. Slowing the fans down still keeps a little air moving but silences the case to a virtually inaudible whisper.
The Eclipse P400S enclosure is designed to support large, tower-style CPU coolers up to 160mm (6.3”) tall. The Hyper 212 EVO cooler fits in easily with room to spare.
Overall, the Eclipse P400S provides basic cooling with very little noise. Some users may be happy with the included two cooling fans, especially if you are using liquid cooling for the CPU and GPUs. However, if you plan to rely on strictly air-cooling, you will most likely want to add additional case fans to increase airflow (and noise).
Liquid Cooling
The Phanteks Eclipse P400S case offers several options for installing single, dual, or triple fan/radiator liquid cooling systems. For this review we installed two different liquid cooling systems, the Corsair H80i and H100i
The Corsair H80i liquid cooler uses a single 120mm radiator mounted on the back panel with a 120mm cooling fan. The bundled 120mm rear exhaust fan was removed prior to installing the H80i.
The Corsair H100i liquid cooler uses a dual 240mm radiator, which we mounted onto the front panel. Unfortunately the P400S does not permit installing liquid cooling system fan/radiators on the top panel as there is not enough clearance between the top of the motherboard and the top of the case.

Is the front face panel
Is the front face panel steel/metal or is it plastic? Which bits are ABS on this case?
The front face plate and trim
The front face plate and trim pieces are plastic.
That is not true for mine,
That is not true for mine, front panel is metal. The solid top vent covers are plastic, the HDD drive caddies, some other misc parts are plastic, the rest is metal.
I worry a little when I see
I worry a little when I see the power supply area closed in like that as I would normally install a fanless power supply in a case that size and would like the surrounding area to be totally open.
That lower section shroud is
That lower section shroud is removable if you don't want it or need more room.
It also has a downward power
It also has a downward power supply vent with an air filter.

Can you fit an HDD bracket
Can you fit an HDD bracket with an HDD in it with that front mounted liquid cooler?
Can u dit a 220 radiator to
Can u dit a 220 radiator to the top is the question then 🙂
I have phanteks p400s can you
I have phanteks p400s can you have front plate on the case while the h100i is installed there or will the airflow not work. And radiator not get cooled
I have the h80i and am
I have the h80i and am interested in this case. I want to mount it in the front like you did with the 100. Are the tubes long enough to do this?
good review, however some
good review, however some shots of the fan controller thats built into this case would be a really big help. it says the controller can support up to 11 fans by use of a splitter, but nowhere do they state whether or not the included fans are pwm or not, and on top of that whether the controller thats onboard can support pwm fans or 3 pin fans.
ive been interrested in this case as a cheaper solution to something like a carbide s as i like the full basement and provides a cleaner end look, but i dont want to have to buy a grid+ or corsair link to controll all fans seperately from the single PWM header on my mobo that my water pump will be hooked too directly. mobo can handle 82w BUT id rather not push it with the pump and 3 fans.
please pleas eplease finish this review or inform me of the lack of explination because phanteks website doesnt give any information on the onboard controller either
Hi, is hdd bay fixed only 2
Hi, is hdd bay fixed only 2 slots or you can screw another one between hdd bay & psu? My local store doesn’t sell those optional bracket. thanks
I have this tower and I have
I have this tower and I have mounted it with fan up but I wonder what si better: mounted with fan up ou fan down?
sorry “power supply” with fan
sorry “power supply” with fan up or down i wanted to say
Looks like your fans on the
Looks like your fans on the radiator are mounted backwards and working against the rear exhaust fan. The blades are curved to be pushing air out the front instead of pulling through the case… Whoops!
