Alright, I bought a PC fan from new egg to exhaust my small 7 cu ft grow space. I was disappointed in how the fan worked, and I thought that if we started a nice little review thread for different brands and sizes of pc fans it would be helpful to alot of people. Again this is for PC fans ONLY! I know there are alot of people using inline fans, blowers, whatever. This isnt about those, this is for small fans for small grows.

That said,

Here is my suggestion for structuring the reviews.

Make: Manufacturer
Model: Model Number
Purchased From: Website or store name
Price: Dollars or other currency (I'm partial to the dollar though!)
Size: metric please!
Bearing Type: usually sleeve or ball bearings, some use fluid bearings
Sound level: In db if you can, otherwise copare it to something common
Powered By: I'm pretty sure all PC fans are 12V, but we all have diffrent solutions for power, list if you are using a speed control as well
CFM: cubic feet of air a minute
RPM: rotations per minute, usually listed on packaging
Pros:
Cons:
Other Comments:
Overall Rating: let's say 1 to 10
Link: link to the website if you bought it online

Okay, hopefully in a few weeks we can have a good database for anyone using a micro cab who wants to know his or her options.

Thanks!

ive been hearing alot of about people useing computer fans in the last couple weeks...and im having a hard time understanding why? I mean..they are so small,how much could one lil fan like that blow out!?
just makes me think too many youngins are trying to grow under their bed without their peeps finding out or something...

Make: Silenx
Model: ixtrema
Purchased From: Newegg.com
Price: $13.99 plus shipping
Bearing Type: fluid dynamic
Sound level: says less than 14db, this fan is seriously silent!, I can barely hear it if I hold it next to my ear!
Powered By: Radio shack multi volt converter, 1000mA. noise rating is for 12 V
CFM: less than 32 is what it says, but I would say its more like 15 to 20
Pros: absolutely silent, also has a remote thermostat attachment, which is nice because it only runs when box gets about 80 degrees or so.
Cons: moves little to no air
Other Comments: Not adequate for my grow box, and for the area I'm using it for is only about 11"x7"x20", I'm using 100w of CFL, maybe for a PC grow this would work, but for me it only reduced temps around 3 degrees.
Overall Rating: 3, really silent, but not moving enough air for my needs

For CFL's computer fans are really convenient. Not everyone wants a big grow room, and PC fans are an easy to find and easy to set up exhaust solution that are pretty silent. Also this thread is for reviews, not your criticisms of PC fans, if you want to state your negativity please do it somewhere else.

It's cool man, I didnt mean to be a dick either. I was just protecting my newborn thread from being crashed right away! I'm sure i just took it wrong. But I'm glad to hear theres more support for the CFL cult! Good luck with your grow mate!

Cheers.

make- dont know- chinese writing. haha
model- dont know
purchased from- small computer store near me
price- $12.00 us
bearing type- magnetic
sound level- silent
power- radio shak 12v ac to dc converter- $20 but well worth the money.
CFM- dont know
one major thing you forgot- SIZE- 120mm
pros- works great in combination with another 120mm sucking air out of my 2x2x4 box with 6 42watt CFLs and a 70watt HPS
cons- broke after about 6 months of continuous use.

in my experience all brands are pretty much the same.. its the size of the fan and power that really matters. also the placement of the fans is critical.. generally the intake should be below the exahust.

heres what mine look like...

not to jack the thread - but to floridasucks - that's one inventive grow box...very nice!

Hey Fuckat7t.
Personally I've tried 12v fans from Zalman, Noctua and many others. I've also tried 240v 80mm fans from Pabst and I wasn't happy with any of them, so I understand why you started the thread.
There's some great info on silent fans here:
http://www.silentpcreview.com/article63-page1.html
and here:
http://www.silentpcreview.com/section12.html

I'm sure I could be proved wrong but in my experience, silence comes at the price of airflow. If you need more CFM then you will get more noise. The mains powered fans from Pabst are the quietest available and cost a small fortune but at 32db they are almost deafening in a quiet room so I wouldn't advise them for anybody. Shame really as they can blow the balls off a charging elephant at 30 paces!
The biggest danger is that in trying to get the quietest fans and running them at 12v for max cooling, there is nowhere to go when the outside temps get higher.
My preference these days is to get well known and high output fans that aren't especially quiet and hook them up to a variable power supply.
All fans are quiet if run at 6 volts and in winter this will do fine. As temps start to get higher I turn up the voltage to 7.5 or 9 volts to get better cooling whilst still not running them at full tilt.
The Zalman and Thermaltake seem to last plenty long enough and blow as hard as any. That's what I run these days.
Just remember it's easier to quieten a powerful fan than it is to get more air out of a silent one.
