Speedster and Fan Growl

Does anyone have a fan on a speedster that doesn't growl when you turn the RPM of the fan down?

I'm trying to determine if it is just the fan, or if every fan growls from the speedster.

I'm looking for another way to control the fan speed. Has anyone tried this device?

my fan dose the same thing

What fan, and what are you using to control the RPM?

I was testing a Sunleaves.com Windtunnel the 4inch. It growls when on the speedster.

The exhaust air from the pressure was louder than the fan when ran at full speed.

yes i have the same one the little blue one its plastic and i have it on the speedster also it makes alot of noise

i think its the fan motor because the low amps running throug it it makes a real loud hummin sound

I think it is because you are just reducing voltage with the speedster, which actually if my theory is correct, is increasing the amperage drawn by the motor, making it run hotter in theory.

I just think it is making the hum because it wants to be ran at 120 volts.

I guess we need to know if other fans do this. People used to always talk about the S&P fans..

mostly because they where cheapest, but do these hum with a speedster?

Bump... Looking for some input on what others are using for fans? and speed control...

I've got one of these on a speedster and it doesn't growl or hum at any speed. You can just hear the airflow slowing or speeding up.

Are you serious, or are you just tring to sell some stuff? That thing is a no name fan. Is it on a speedster?

If that is the case, I feel ripped off.

We need some more reponses on this thread..

Dead serious! Just relaying my experience, not affiliated with the manufacturer in any way. It may be no-name but it has everything a more expensive fan has except the brand name.

And yes, it is on a speedster and I ran it through the full range of control and it was completely silent minus the sound of the air flowing through the duct. I checked before posting to make sure I wasn't making an ass of myself.

I run a can33 combo, on a speedster, and I agree with the OP, at the lowest setting, I can hear that little hum as well.

on the highest setting, it sounds like a jet about to take off.

Huh, very interesting.

I might pick up one of the S&P's and try it then.

Dont bother, my S&P 200x gets owned by the speedster, hums like a motherfucker. My only fix, ditch the cheap ass dimmer switch, and buy yourself a cheap 3amp Variac. It controls the voltage you apply to the fan is the better route, got mine for 45 bucks i think.

Don't buy a speedster. It doesn't lower voltage. It turns your fan off and on at a high rate. Your fan makes a humming noise on start up when plugged in. If on full, that noise goes away in a few seconds. However, if it is being turned off and on constantly, it never gets a chance to get through that start up "hum".

Actually talked to Can Fan today. Tech guy said do not use the Speedster. It can dramatically shorten the life of your fan. He offered up their variable transformer (the device you want to use to CORRECTLY control the speed of your fan), it was, however, $300. Here:

So I looked up variable transformers myself. Found this 5 amp one (I don't know how much amperage your fan pulls...make sure thats enough):

I don't know if it will work correctly. But he said theirs was a variable transformer. I'll try to remember to let you know once I find out.

haha you found it!

Thats the variac that i ordered. it turned out being cheap and red and from china, and i'd heard a couple horror stories about one melting under the current, but ive never had a problem, and for not that much more its literally the best option.

DOWN WITH THE VARISPEED AND SPEEDSTERS! lol

I first tried the Speedster and it hummed big time.

I ditched it for this: http://aeroponicsnmore.com/climate-control-ventilation-c-23_5/temp-2v-fan-speed-control-variable-idle-setpoint-p-181

It's almost identical to the 1V you listed, but different because it gives you the option of on or off at night. NO HUM.

Yeah, this one is new, or the newest one out, acording to there web site.

What kind of fan do you have it connected to?

I have mine connected to an 8" Elicient (750cfm) inline. I've also tried it on my 6" HO Can Fan.

I'm in the process of designing/building a new grow. It will be a closed-loop 4x8 tent. I will have the 2V connected to my fan-filter with the exhaust returning to the bottom of the tent. I will attach a 8" Ice Box to the return for AC. With Co2, it will be a VERY effective self-contained growroom.

After watching that video, it does look like he is using the same GrowZone controller, but it might be the V1.
How variable does it speed and slow the vans down? I mean does it slowly creep up to full speed, or how does it work?

How does it keep the 60hz sine wave, do you know?

It's likely this has been mentioned in other threads but all of the vortex type centrifugal fans I have ever owned have a type of speed control built into them via the motor taps. In the main wiring box mounted on the side of the fan there will be a screw terminal strip, connected to this will be pass through for the negative and earth, then your supply positive can be wired to 1 of 3 terminals connected to different 'taps' on the motor winding which represents Low Medium and High.

On every fan I have ever owned you can easily change the setting via the terminal strip or mount and wire in a 3 way switch to change speed setting.
Don’t know if this helps but by doing this you can do away with speed controllers and variacs. The motor is obviously designed to do this so there are no additional noises.
I currently have 3 of these fans in 2 rooms and have wired up 2 of the taps separately, the highest speed for all fans are wired to the light timers so during day periods the fans run high, the lowest speed is wired to another timer which kicks in during night periods to keep a lower/quiet airflow going. You could also easily wire all three taps/speeds up to activate in high temps or humidity etc.
Hope I haven’t gone too off topic, of course there are many cases where specific speed control is required but I find the 3 available settings are great for my needs.

To state the obvious...if you do make changes to the wiring make sure the power is disconnected first!
