Fractal Design Define R3-fans=Loud at idle?

post #1 of 7
Thread Starter 
Hey guys!

I think that my FD R3 is a bit too loud for my taste at idle and I am quite sure that the included fans is the problem but I'm not completely sure so I'm asking you guys if you know anything about the including fans or have heard anything about them being loud?

My other 3 Noctua NF-P12 fans are controlled by a fan-controller and when I turn them off the noise is still there so I'm sure that they're not the problem. The included fans are running at stock speed though which I think is 1350RPM and that sounds a bit high at idle to me.

I know that I'm very sound-sensitive so I don't know if I'm just "hallucinating" or if the including fans really are a bit loud that's why I need your confirmation guys thumb.gif

If they are running 1300rpm you will hear them.

I changed mine to PWM fans and control them with PWM splitter using PWM signal from mobo CPU fan socket... same as my CPU cooler uses.

Anything with 120mm and more than 1000rpm can be heard through a closed case. I have the same case and could hear the fans clearly.
Just get a fan controller and throttle the Fractal fans to 700-1000rpm and you will be fine.

One word of warning though, the older generation of fractal fans (before the R4) is not terribly reliable. They are ok since they basically cost nothing if you get them with the case, but don't expect them to last for many years.

The R3's stock fans aren't the greatest. As Stompy said, bringing them down in rpm is probably your best best aside from replacement, either with a controller or some voltage limiters.

If you decide to change fans you might consider going to 140mm fans.. preferably PWM. I did and it's not that hard to do.

If interested I could post a little tutorial for both modding R2/R3 cases for 140mm front fans and running case PWM case fans on same PWM signal as CPU fans.

Hmmm, I'm not the most handy person when it comes to modding etc, how hard is it?
And is it really worth it just to be able to mount 140mm-fans instead of 120mm-fans? If I buy new fans I'm certainly buying Noctua because they serve me well at the moment.

The hole is much bigger than 120mm diameter.
New Fractal Design Define R4 is 140mm fan.
As for hard well I guess it's all relative. If you aren't handy it's probably too hard. Have to drill out rivits to move the fixed HDD cage back in R2. Not sure about R3. Cut a piece of stiff plastic to fit in the front of case against the panel. Cut 2 holes 140mm for fans. Drill mounting holes for fan mounts in plastic (120mm fan mounting) and holes to mount plastic to front of case. Drill 4 holes to mount HDD cage back in about 10mm farther back in case. If fans are 140mm mount you don't need the plastic piece. Just drill the front of case with 140mm mounting holes. I used TY-140 fans so needed to use the plastic piece to mount the fans. I put Silverstone magnetic mounting filters in. Could use DEMCiflex magnetic mounting filters.
