I was thinking that the extra loading might affect it to, but I can't hear it on the lower fans (even will my head halfway inside the case smile.gif )

I’ve tested a few other case fans with the CM controller. Not a scientific test by any means, but a subjective ear-to-the-fan sort of trial. I’ve used Noiseblocker fans in three other builds and have found them to be almost silent. I had hopes they would perform well. I had plans for mounting Noiseblocker NB-BlackSilentPro PK-2 140mm x 25mm Ultra Quiet Fans ( 1200 RPM) as horizontal exhausts on the top. Unfortunately, they tick noticeably on the LOW setting; they are a little better on MED, but a faint tick is still audible. I had better luck with the Noiseblocker NB-BlackSilentPro PL-2 120mm x 25mm Ultra Quiet Fan (1400 RPM). It emits a light ticking on LOW, but was nearly quiet on MED. Finally, I found the BitFenix Spectre LED 140mm Fan was the most unobtrusive of the bunch. Only a very slight tick audible on LOW, none on MED. However, BitFenix fan does not seem to move as much air as the NBs.

Also as has been noticed by others, if multiple fans are connected to a single switch, the ticking becomes more pronounced.

Well, speculating the obvious I ran a few test of my own on the controller. I'm sure we've all come to realize that this is not a true PWM circuit. For some unknown reasoning CM decided to pulse the 12v instead which explains the ticking noise and the pulsating LEDs.

I purchased a full set of Phobya's to install into the case and fortunately they only have a very minor tick on low speed. I also had to cut the LED wires from each fan and use the original LED wiring supplied with the case and soldered and sleeved to use the controllers LED on/off switch (direct 12v).

If I would have only known the childish designing that went into the controler I wouldn't have touched this case for the price I paid for it. Live and learn I guess........

Hey would love to see how you soldered and sleeved the cables from the LED fan to the controller

I'm out of town (on the IPad) right now but I'll post what I did when I get back. The Phobya's use a switch right at the fan which, when in the on position, closes the 12v loop to the LEDs. Since the fan is supplied a ground through the controller it only took one wire to the controllers LED connector.

Well talking to one of the CM reps and he stated that a Windowed side panel maybe in the works. Not sure on the ETA but hey I can wait.

I have My h100 in a push pull with 4 fans and the airflow is INTO the case... I have not notice any adverse effects...i'm gonna experiment with both setups and post the results...

here is mine. im happy with it so far other than the fan controller issue. i wish there was a controller that would fit in the place of the hot swap bays since i dont intend on using them.
