I jhave been working on upgrading my 14g Bio Cube to LED's for the past couple of weeks. I am just about finished and found another small project to add to the list. I found a very simple little circuit that will control the hood fan speed based on the temp of the heat sink and turn off when not needed. I will have some picture's soon . Here is the link to build the fan controller. http://www.heatsink-guide.com/control.shtml

 

I built my own custom pcb for the dimming circuit and I modified the stock fan header pcb to be a 12v power distribution module with the fan controller built in.

 

Parts consist of the following:

 

6 CREE CW

6 CREE RB

2 MEAN WELL ELN-30-27D DRIVERS

1 NANO TUNERS CUSTOM MACHINED HEAT SINK

2 SUNON FANS KDE1205PHV1.MS.A.GN

1 ALUMINUM ENCLOSURE TO HOUSE THE MEAN WELL DRIVERS

1 CUSTOM MADE DIMMER CIRCUIT: USING DIRECTIONS PROVIDED ON THIS WEBSITE FOR THE PARTS

1 MODIFIED FAN HEADER WITH BUILT IN TEMPCONTROLLED FAN OUTPUTS

Heat sink mounted all wired in using stock wiring. I wanted to maintain all features of the bio cube. I kept the waterproof ballast connectors, internal wiring and the connectors to connect the white and blue strings of LED's.

I haven't added a fan yet, just using the stock fans. I will be adding a 60mm over the top of the heat sink blowing down onto it.
