Hello all,
I thought I would share this little mod on my JBJ Formosa DX power compact light fixture. I got this unit yesterday and first thing I noticed was the fans were pretty loud.. especially when trying to watch TV. Anyways, today I installed 3 potentiometers to lower the RPM of each fan.
The fans on these units are 12 volt DC and each has its own independent power connections.. I wired in the potentiometers and mounted them on the back of the fixture.
Turning them down reduces the noise considerablly and it only cost about $10. Pretty cheap and it will keep my wife off my case cuz of tank noise..
Here is a pic of the adjustment knobs.
If you want any more details please let me know.
Cheers,
Jerid
