can fan any heat?

[Wacky Tobacky]

I want to sound proof my fan. i already have a muffler but i want to maybe put the fan into a box or something and try to kill the noise. i havent run these before so have no clue about them. i dont want to start a fire or anything.

what if i were to wrap the whole fan around with a blanket? i mean i want to kill all vibration and noise comin from this thing. its gonna be in my bedroom and i want to beable to sleep at night.

Please don't hurt yourself laughing at my pathetic design and execution. Power tools mixed with flu induced panic is a bad mix. That said, it works really well. Combined with Speedster and insulated duct (note: that's 4 levels of noise suppression altogether) it was, with garage door open, still audible at my neighbors door across the street.

You can tame it enough to sleep next to. You know what the noise is and it soon becomes background noise. However, no one else will know. They WILL ask "What the hell is that noise?" If you can't put the fan in the attic, be prepared to lock your doors and keep everyone out.

lol ive seen that before and thats what i was trying to do.

does the can fan produce any heat?

i was thinking about just wrapping it up in a blanket and running it. i tried it out and it does the trick. kills ALOT of noise and absorbs pretty much all the vibration.

im just worried about maybe the blanket some how catching on fire. do you think thats even a possibility?

oh and thanks for replying freezerboy you seem to be the only one that helps me out.

The fan is pretty much self cooling. I've seen some who fill the entire space with foam, which I'd have done except that my disease addled mind drilled in the side and out the end and foam would've blocked the intake. What can I say? 103º fever, panic and power tools make for bad decisions.

Thanks for all the info man.

I had my fans in a box crammed with foam, blankets, and insulation. Could still hear it..
Currently, my Vortex is wrapped with Dynamat, then a layer of sticky foam (used as insulation for water heaters). Even running @ %75 (with a speedster), I can still hear it (barely). Freezer is correct, you may get used to it (I have), but people who don't listen to it everyday will notice immediately. If having guests is unavoidable, have some other noisy distraction (TV, radio, garbage disposal) at the ready to mask the quiet whir of a fan..

Use insulated ducting, it will quiet down the sound of rushing air. Run your fan at < %100 (they seem to be super loud @ full speed). Have a distraction (I use my TV). Build a sound box if you have room.

As said, the fans are mostly self-cooling. I have a 4" canfan 170 CFM in a custom growbox. Outside of the box the temp is 70 F, inside is 73, and the exhaust is 74.5. With lights out, the exhaust is still 1 degree higher than the temps inside the box. So, the fan must be making that 1 degree difference. In other words, the fan doesn't produce much heat, at least in my setup.

thanks guys. ya i got it wrapped in 2 blankets. its doing a good job keepin the noise down. i also got a muffler. but at night when its dead quiet you can definitly hear it.

i have it running at 100% tho. i just ordered the thing so i can adjust the speed. there is barely a a temp diff from inside the tent and outside cause my fan is 270CFM and its going 100% and the vent is connected to the lamp hood.
