New Fan in RM100

Post by Dr.G » Sun Jun 28, 2020 9:46 am

I grew tired of my noisy fan in my RM100, especially when playing quietly at home in the evening. I was searching for threads about this mod, theres not really much around or I was just to stupid to find it. So I thought I just do my own thread of exchanging the fan.

While searching for a quiet fan, I came across Noctua. It`s an Austrian company specialized in quiet computer applications where I bought a fan. The fan comes with different adapter cables to regulate the its speed (2000, 1650 or 1200rpm).
Fan Modell is NF-A8 FLX. The dimensions of the fan are 80x80x25mm and it`s operating at 12V (in case you want to use a different fan).

The Noctua fan comes with an 3Pin connector (yellow, red, black). Simply remove the connector at the end of the (adapter) cable, isolate the yellow cable and connect/solder red to red and black to black from the cable powering the stock fan. Isolate everything carefully with duct tape or better with heat shrink tubing.

The fan is not directly mounted to the chassis but on small spacers leaving a gap between the fan and chassis of approx. 0.5cm (not sure if this spacers dampen the vibrations of the fan?). As the fan does not blow in air but sucks out air from the chassis, I isolated this gap with self adhesive foam.

The fan is now running at 1200rpm and its so much more pleasant, as the noise reduction is huge :)
