Replacing intake fans in R4 (silent fans recommendations)

post #1 of 12
Thread Starter 
Hi All,

I'm in the quest of getting my computer quieter and i made a thread in the PSU section regarding replacing it and got some solid information. I now am looking to replace the fans that came with my Fractal Design Define R4.

I replaced the fan in the back with a Antec TrueQuiet 140mm as it did not fit in the front. I now have two Fractal Design Silent Series R2 in the front.

So what am i looking for?

Silent 140mm intake fans.
Need to fit the R4 Intake bracket. This means it probably has to be full framed.
Preferably something not over 1000 RPM, but not important. Have fan controllers.

As you may know, the front of the R4 is blocked for noise purposes so i assume i would need a fan with high static pressure?
Also, the bracket that fits the fans in the R4 is of a clip on design, and as i said earlier, i tried fitting a TrueQuiet there without luck. Granted i never bothered checking to see if it was moddable, so if anyone have any suggestion, or perhaps a link, where i can see how other users fitted there fans without the stupid clip-on bracket. Can't believe i missed it when i bought the case.

Thanks in advance!

I'd sayPhanteks PH-F140, but they are expensive.

I'm also partial to thermalright 140mm fans. Dunno how they work as case fans.

I'm curious as to what you'll end up getting. biggrin.gif

I went with Noctua NF A14 PWM fans. Very quiet, cool well and fit in the R4 with no modification. Their max speed is 1500 and with the little low noise adapter they spin at 1200.

You might find this thread interesting.
http://www.overclock.net/t/1484035/fractal-design-r4-case-airflow/0_20

Phanteks PH-F140XP and NH-A14 PWM are good choice. I use many Thermalright TY-14x series fans and have modified them to be square. They than fit in Define R4 front nicely once modified. Here's a pic of TY-147 fan in front of Define R4


Here are before and after mod pics of TY-140. I painted the housing black. I cut slightly too much off. The cut should just touch the center area of fan hub. The tan area on this cut is about 0.3mm too much.


Here the TY-147 is only £5.17 and TY-143 is £6.99.

TY-140, 143 & 147 have same design
TY-140 & 147 are same 1300rpm 74cfm 0.2a fan in different colors.
TY-143 is ball bearing and 2500rpm, 130cfm, 0.6a
TY-141 is ball bearing 1300rpm 74cfm 0.2a.

You might find 2nd link in sig helpful. 1st link of you want automatic speed control. wink.gif

Thanks for the suggestions! Forgot i posted this thread so sorry for the late reply.

Wouldn't modding the fan cause them to become unstable or something? I always believed that fans was balanced and that you shouldn't modify them because it could cause worse cooling/noise issues.

While true for the blades the housing does not move so no balancing to deal with. In serious flow patter testing it has been found that the round sides of housing flow a cleaner patter than the square sides. But this is not really an issue. I can hear no difference between modified and stock.. and several others have done this mod and been very happy with their results too.

Cool, thanks for the information. I'll probably order some TY-147 seeing how inexpensive they were.

Where are you located?
As a retired bespoke joiner with tools of trade I trim them down with power miterbox with good blade. Can also use a slide table on table saw with good blade.

You should definitely check out some Noctua NF-A14s I just installed 2 140mm in the front of my R4 and 2 NF-F12s on my H100i on the top mounts and they work wonders, a little pricey but can you really put a price on your high end components? thumb.gif
