I've got a DR60 and a 4" Ruck fan and am wondering if this is good enough for it? Thanks in advance.

Looks like it should work fine.

It should work. But just be aware that fans are generally designed to be run at a certain speed, using a speed controller can often reduce the lifespan of the fan and can also be louder than running at it's rated RPM

i have never experienced that tip top toker... in general they always run alot more silently and are not stressed nearly as much as running full speed where did you get this notion?? that slowing it down decreases lifespan id like to learn more cause if thats the case im screwing both my 6" vortex and my 4" vortex alll up...

to junglist.. try harbor freight or hardware stores.. its a simple speed controller EDIT* im in the U.S. do you guys even have hardware stores..?? lmfao

Some inline fans handle the attenuation better than others. Vortex fans are pretty good. A crappy dimmer will screw up a crappy fan pretty quick. If you want a good speed controller:

If you don't know how to set it up:

Why is it important to get it right?:

I can't tell you the exact science behind it, but there are many types of fan and types of controller, and in certain circumstances running a fan at reduced RPM can cause components to overheat. Some fans are designed to be run at a set speed for best acoustics, a drop in RPM can make the fans acoustic design invalid. I've witnessed it with a couple of fans, and it was not so much that they got louder, but the pitch altered to the point that it was well within your concious audio range, if that makes any sense

Another issue with all fans, is the air flow created help to cool the motor. If air flow is slowed to to much (based on the cfm of the fan) it can wear down the motor quicker by making it over heat. Most quality fan motor handle this by the pitch design of the blade.

The problem lies in that of the type of Motor that is being used in the fan. There are many different types of Electric motors used. A standard light dimmer just "squeezes" the voltage dropping the overall current, slowing the motor. But when the current is dropped below the point at which the motor is designed for it burns its self out over time.

This is a router speed controller, they also sell them as a FAN speed controllers at Grow Shops - $17.99

Thanks for the info guys. Although I'm pretty much used to the noise now lol.

Hardware stores? Of course we do, the village ironmonger is only 80 miles away.

GoldDog, thats frikn awesome. great find man.
