H100i replace fans? in fractal design define r4 window

Huang Ray · May 17, 2014

I decide to use either
Arctic f12 or
Noctua f12
I do not care about the color, but
Arctic f12 is cheaper (10 vs 20 dollars)
However, people said it will lower the performance.
If I replace it, I want to use push and pull, but can though fit in fractal r4? with i7 4770k on asus formula. My ram is kingston beast 1866 (just in case).
Is the replace worth it?
If I don't replace it, will it be very loud.
Fractal r4 (i heard) is very quiet. So, if the h100i stock fans is a little bit loud, i think it is ok for me.

Push pull is mostly pointless, especially with the h100. Best is to go with pull alone. Go with the noctua, best fans around.

Is it necessary? I do not want to waste 40 dollars

and.... I heard it decreased the performance

Corsair h100i - Fan Speed: 1350 RPM, Airflow: 77 CFM, Sound Level: 37.68 dBA.
Noctua NF-F12 - Fan Speed: 300 ~ 1500 RPM, Airflow: 74.3 ~ 93.4 CFM, Sound Level: 18.6 ~22.4 dB.
Arctic f12 - Fan Speed: 300 ~ 1350 RPM, Airflow: 57 CFM, Sound Level: ~ 25 dBA.

Note: dB is the raw sound pressure and dB(A) is filtered to better reflect how our ears perceive it, so the 18.6 ~22.4 dB measurment of the 'Noctua NF-F12' can't accurately be compared to the others.

"...but can though fit in fractal r4?" - Yes, it will be able to fit in the case. The h100i will have to be mounted to the top of the case.

"Is the replace worth it?" - No, it's not. The fans supplied with the Corsair h100i don't require replacing, they're fully functional and perform very well in tough conditions.

"If I replace it, I want to use push and pull..." - I agree with 'woltej1'. This method won't function correctly on the h100i. To optimise air flow and performance the fans need to be working together, not in opposite directions.

"If I don't replace it, will it be very loud." - The h100i can become very loud; if the system is pushed to full throttle, doesn't remain loud for very long, if you will even experience it at full throttle.

If you still plan to replace the fans, then I'd recommend using the Noctua NF-F12 fans - together in a push setup. Only in a setup with those fans could you revival the Corsair's default fan speed and airflow. Whatever you decide, make sure the RPM and CFM match that of the Corsair fans; they would sold with that cooling system for a reason.

don't do a push set up, do a pull set up, It makes it easier to clean as dust in a pull set up accumulates on the bare back side of the radiator where in push it builds between the fan and radiator.

So, just use the stock fans and pull? i am kinda confused

Cables · May 17, 2014

Yes, apologies, use a pull setup; my mistake.

Yes Huang Ray, "...just use the stock fans...". The h100i fans should be setup in a configuration which directs the flow of air away from the radiator.

So, the air is intake or outtake?

“So, the air is intake or outtake?” – It depends on how you want to set it up.

I'd recreate this diagram: http://i280.photobucket.com/albums/kk198/Nf650i/Untitled-8.png

Cables :

If I want one fan in the front intake, and the rear fan outtake.
Should the H100i fan intake or outtake?

Cables · May 18, 2014

"Should the H100i fan intake or outtake?" - It should "outtake". The h100i air flow should direct the warm air from the radiator out of the case. I'd not recommend blowing the heat from the radiator into the case.

So, your point of exhaust (for your h100i) is going to be the top of the case; allowing the fans to blow the warm air out, with a fan on the front and rear of the case to keep the air flow going, in one direction.

If I did not install a fan on the bottom, should the top fan be exhaust?
Also, if I instal a fan on the bottom,
should I pick Noctua A14 FLX, A14 PWN, OR A15 PWN? ON THE FRACTUAL R4

Huang Ray :

"If I did not install a fan on the bottom, should the top fan be exhaust?" - Yes, as a rule of thumb the top fan should aways be acting as an exhaust.

"...should I pick Noctua A14 FLX, A14 PWN, OR A15 PWN?..." - The NF-A14 PWM appears to be the best fan. Ensuring you have a 4-pin connector; either by means of an adapter or supplied through your motherboad.
