Replace stock fans in Phanteks Evolv ATX?

post #1 of 6
Thread Starter 
I'm about to build a new system and I've settled on the Phanteks Evolv ATX case. I'll be using the following hardware:

Asus Maximus VIII Hero Alpha
i7-6700K
Swiftech H240 X2 Prestige
Corsair Vengeance LPX DDR4
Asus Strix GTX 980Ti
Samsung Pro 950
Samsung Pro 850
4TB HDD
EVGA P2 850w PSU

In theory, the air should flow like this:



Phanteks quotes the following specs on the stock PH-F140SP fans:

Speed (rpm) 1200 ±250 rpm
Max Airflow 82.1 CFM
Static Pressure 1.33mm H2O
Acoustical Noise 19dB

I can't seem to find the exact model of NB eLoop fan that the H240 X2 Prestige uses but Swiftech claims the following on their site:

Speed range PWM adjustable 500 ~ 1800 RPM
Airflow < 123 CFM
Static pressure < 2.35 mmH₂O
Noise level < 36.4 dB/A

I realize that these numbers don't necessarily represent "real world" performance but I'm wondering if I would be better served by replacing the stock case fans with something else? If so, what? Thanks for your advice!

Far more important than changing the intake fans is making sure that you seal all of the openings in the radiator mount. Air seeks the path of least resistance, the Evolv ATX top exhaust is very restrictive, so leaving the big hole in front of the radiator open causes a bit of a mess. The radiator exhaust will simply go forward (the path of least resistance), only to be sucked right back into the radiator to be warmed further....lather, rinse, repeat endlessly. This is a known issue with the Evolve ATX, but thankfully one that can be taken care of in ~5 minutes.

As far as replacing the stock intakes, you ideally want more intake than exhaust. If the specs on the Swiftech site are correct, you are going to need 250CFM+ on the intake. You could do something along the lines of three 120mm 2150 rpm GTs or Noctua iPPC 3000, or a pair of 140mm iPPC 3000. Keep in mind that you will have a lot of air movement, and will have to do some work with the fan curves to keep the noise in check and intake greater than exhaust.

What ciarlatano said.

I would probably not even use the back vent, and if it was used it would be intake.

Thermalright will be releasing a square version of their TY-143 fan (and TY-147A) in not too distant future .. TY-147A Sq and TY-143 Sq. Probably a month or so.
I've been playing with a couple of the first production run. Same performance as TY-147A & TY-143. Might have to get some more and run some comparison testing in Phanteks cases.

On my PH-TC14PE I like the TY-147A better than PH-F140HP. Would be nice to try PH-F140HP II .. even though specs show it moving less air than F140HP.

Thanks, Doyll. As I'm sure you know, my Strix GTX 980Ti doesn't use the reference blower cooler so it will exhaust some hot air directly into the case. With that in mind, do you still think the rear fan would be better as an intake than an exhaust? I undertand that it's desirable to have total intake > total exhaust but would I be better off having a rear exhaust to pull some of that hot air from the GPU out and then trying to find something to replace the two PH-F140SPs up front to I still end up with intake > exhaust? Thanks again for your advice!

Kinda hard to say. I would remove all PCIe back slot covers and with 2x front and 1x back intakes combined with 2x top exhaust the extra intake air will push the heated exhaust from GPU back and out of case. "Ways to Better Cooling" link in my sig might be of interest. 1st post is index, click on topics to see them. Post #5 is basic guide to case airflow.

i have been figuring out my setup for the same case as well. my hybrid 1080ti and 7700k definitely run hotter in this case then my hybrid 980ti SLI 4770k did in my storm scout 2. though i did have both gpu's in push/pull. both the 4770k and my current 7700k have been dellided. when i am not feeling lazy i will replace the thermal paste on my GPU with grizzly kryonaut (which both my old cards were applied with).


my basic setup with math.

3 noctua nf-s12a fans in the front as intake - i tapped off any space between the fans and case=
189 cfm total
54.4 dba total

rear rad (GPU) nf-f12 pwm intake =
55 CFM or 2.61 H2O (radiator pressure spec)
22.4 dba

2 nf-f12 pwm for exhaust top (h100i rad) -with the top tapped off to reduce hot air re circulating:
110 CFM or 5.22 H2O (rad pressure)
44.8 DBA

i too go for positive air flow (more intake than exhaust). i also tapped off all opening in the back with black tape to ensure all pressure is hopefully forced through the top rad.


i have been considering changing out the intake fans with noctuas industrial line which are 2000rpm. not sure if its worth it. i was thinking of at least starting with the rear intake since its the only fan that can be seen. maybe doing the 140mm fan with an adapter to the 120mm radiator. or just doing the 120mm industrial with no adapter.

a 140mm to 120mm adapter acts like a should, which is said to help with the pressure since there is a gap between the fan and rad. in my old setup, i did run phobya 7mm shrouds on both gpu's on both pull and push sides. its hard to tell if it helped. but it made me feel better inside.


a mod on phanteks was to add small spacers on the front panel (the silver panel that snaps over the fan filter). that panels clips (part that push into the actual case) are on a bracket, the bracket is screwed into the back of the front panel. so he put spacers between the clip bracket and front panel. this gave him a few mm's of additional space along the front sides and bottom which in theory would allow for better air flow intake.

the phanteks forum aslo recommends to site the top piece on top of the case, dont click it in place, just let it sit. this gives you a few mm all the way around for better exhaust.

one other mod i saw was a guy who used a water jet to cut out a cool design on the top of the case to allow for a better air flow exhaust path.
