fans

[zlwags85]

any suggestions on small 4 inch fans that I could buy locally somewhere? Or how to get a computer fan to run on AC. The temp in my room for some reason is about 80 right now and I think the tanks will be fine but figured i should get going on some fans. The two tanks are at 83 degrees.

best guess is probably good ol' Radio Shack.

I got a 4" personal fan from Walmart for $5.99 and it works awesome on my tank. They are in the fan area of course and are in different colored boxes.

Ask brad23 I found some nice 120mm 120v fans for his canopy for 15 bux a piece they are pretty nice.
They move (iirc) 80cfm at 36dB

lego/brad,

in the market for a couple of those. where did you get them??

[LegoZ81]

the one I am currently using is a 12v pc fan. it is a YSTech 120mm fan that moves 131cfm @ 12v @ 48dB it is currently overvolted to 20v (that is the power supply I had on hand.)
beware though even at stock voltage mine is a screamer!
I got it at www.plycon.com. I'll shoot this thread to Brad.

Actually I ended up paying $13 a fan. They are 33db and they keep my temp consitant with 500w of MH over my 75g.

I'll try and find the link, I think he gave me a wholesale account as well.

thanks for the link. this may be a dumb question but what does CFM stand for? and is the 33 db fan very loud, im not up to par on that either. Thanks

[brad23]

They are a little loud for my liking but not bad. It's more of a humming sound than anything else.

They really move some air.

[LegoZ81]

CFM = cufic feet a minute
it measures the volume of air the fan moves a minute
simular to a GPH rating (gallons per hour)

you should some where be able to find a dB explanation chart somewhere that plots various common noises so you can compare how loud the fan is to something you know

[zlwags85]

ah makes sense, yea the only reason im concerned with the noise is that both tanks are in my rooms and i already have to listen to skimmers and pumps and the fans on the lights.

You may want to check out xoxide.com also, it's a computer parts store, but the fans are the same. 120mm is equivalent to a 4" fan. Also, newegg.com is great too. They both have good prices and are quite reliable.
