LED fans for Hyper 212X?

[jpmeneses21]

I would like to replace the stock fan on my hyper 212x with an LED fan of near or equivalent performance. Not that the stock fan's performance (at 80 CFM, 2000RPM max) is poor, it's great actually. I'm just changing it for aesthetic/eyecandy purposes, and use the stock fan as front intake or rear exhaust (via fanhub) instead since my fans in those areas are a bit lacking in terms of airflow.

I'm currently looking at these LED fans which claim to have good static airflow. The only gripes I have with these is that they're 3-pin, not the standard 4-pin, PWM fans use. Is that going to be a problem?

I'm fully aware that changing the more powerful stock fan will result in slightly higher temps, but that's tolerable as long as the temps stay under 60ºC on load.

My currents temps range from 29ºC minimum on idle, to 51ºC max when I'm gaming. I'm using a Haswell i5 4570, in a Cooler Master Storm Scout 2 case, with 7 fans (2x front intake, 2x top exhaust, 1x rear exhaust, 1x HDD cage intake, 1x bottom intake)

Theoretically, if you plug in a 3 pin fan in a 4 pin CPU header, it will always run at its max speed and system won't be able to regulate fan speed based on high and low temperatures.

So running always at max speed is not really an issue if their max noise output is not terribly high. You can go for these fans if you feel you not necessarily need the ability of CPU fan being System controllable. And your temps look good, you might see some rise in temp due to reduced CFM, but as your case is heavily ventilated it shouldn't be something great.

I would recommend that once you plug in the 3 pin fan you actually keep the case open when starting it the first time, and verify that fan actually runs. Murphy's Law can be a bitch sometime. And when it is running you can install a software called speed fan to verify the speed at which the fan is running , it should be close to the max RPM stated by the FAN.

Yes, I don't mind a little noise. Actually, I'm one of those people who can tolerate a bit of the humming sound from the fans, and yes, I actually prefer the fans to run at max speed at all times.

Another I would like to know if a push-pull config really works? Based on what I've read so far, people are 50/50 on this one. Some are saying it works, while others say adding a 2nd fan to the heatsink is useless.

Well i do not know if you would consider it pointless however i can tell you based on my experience
adding a second fan only cools 1 to 3C better .

It would only reduce the temperatures further by a few degrees... unless you do overclocking where a drop of even 1 degree is really appreciated to have, the amount of effort to add another fan, maintain it and the initial cost involved is not worth it.

So in short

if you overclock : add it.
If you don't overclock : don't add it.
