Has anyone used Lian li TR-3B fan controller?

This one: ... ometer.htm

I wonder if it has PWM drawbacks, like making fans noisy?
Also, does anyone knows the adjustable voltage range of this controller?

Yeah I'm using one in a MSI SFF. The voltage range 7-12V. I had to use a fanmate to lower the voltage(between the controller and the fan/s). You can set the idle speed separately for the three channels. And using the three temperature probes, set a temperature point that the fans go to 100%. It's basically a two speed fan controller, individually adjustable for each fan.

I used M-Cubed attenuators in my setup, so there is no PWM noise.

FWIW.....Logysis makes the same unit in a small housing. But the guts are the same. It usually costs less. Not that great.....IMHO. But they work ok.

Do you know where i can buy, in the US, some "M-Cubed attenuators"? Also, do you use by chance this combo (Lian li fan controller and Nexus fans), without the attenuators? Are Nexus fan affected by PWM noise?

USA link to fan attenuator

These things work, particularly well with a PWM controller, but also with an analog control. There are two fan connectors on the thing, but only one voltage input.

I have never used these things on a Nexus (don't have any}.....but I do use Yate Loon fans. These fans are affected by PWM control, and the attenuator eliminated all the PWM induced noise. YMMV
