Good, quiet, and inexpensive fans...

NeveSSL · #1 12/14/2007, 12:58 AM

Just thought I'd give you guys a heads up.

I record at home, so a quiet PC is... helpful.

I was looking at SilentPCReview.com. These guys test things like CRAZY for noise!

Anyway, I'll get to the point. They didn't test the stealth, and just looking at manufacturer numbers, its slightly less. It does 47CFM at 28dB(A). Thats slightly quieter and slightly less air than the Stealth, but here is the reason I am telling you guys about these.

Ultimately, they are GREAT fans... very quiet... and you can get two of them for $13 SHIPPED on eBay.

Just search for D12SL-12. Go to the very bottom in the eBay stores section. There is one that is $7.99 OR Best Offer with free shipping from the seller Thermalmaster. I just offered to buy 2 @ $6.50 each and they accepted!

I just thought I'd mention these as a great alternative to the Stealths as they can be a bit expensive. These spec VERY close and I can say personally that they're very quiet. I have two on my computer for recording and I'm probably going to order two more for my canopy when I build it in two or three weeks.

Just thought I'd share!

And, FWIW, I bought mine about 4 or 5 months ago... so this seems to be a long term deal. If you can't find them, feel free to PM me.

Have fun!

Thanks for the tip. That's a good deal for 120 mm fans. My hood can only hold 80 mm fans though.

NeveSSL · #3 12/14/2007, 02:50 AM

No problem.

Wish you could use them!

CompUSA is going out if bussiness, I dont know what states they are in but in ohio they will be closed by 12/31. They are at 10-30% off in my area. 20% off of fans may be worth a look

I am using these fans which are true 9dba very silent

and does a perfect job cooling

This is what I'll be buying to circulate air around the orchids in my living room:

Vantec Stealth 92mm Case Fan (2600rpm)
Specifications:
Fan Size: 92x92x25mm 3.62x3.62x0.98"
Rated Voltage: 12 V
Rated Current: 0.07 Amp
Air Flow: 28 CFM
Rated Input Power: 0.84 W
Noise: 20 dBA
Rated Speed: 1750 RPM
Bearing: 2 Ball Bearings

That's right, 28 CFM at 20 dBA, for those of you in the know thats SUBSTANTIALLY quieter than the 27 etc dBA fans because the way decibels are calculated

NeveSSL · #7 12/14/2007, 05:33 PM

28CFM is also almost half of 53CFM.

If you wanted more air at the same level of dB, you could get a 120mm fan and ramp the voltage back.

And dBs are logarithmic... that be why 27 is quite a bit louder than 20, but they're ALL reference points. There's no true value.

ANYway...

Related question. What could you use to wire this up to a std house outlet? I could use a few of these but I have no way to power them.

miwoodar · #9 12/14/2007, 07:23 PM

Cut the end off of a 12v wall adapter and connect the wires to the ones coming out of the fan. Connect and reconnect the wires until you find the two that run the fan (most fans have more than two wires coming out of them). Improve the connections so they are safe and you're done.

If you want more info - not usually necesary...

You can run multiple fans in series from one adapter as long as the milleamps of the fans do not add up to exceed the milleamps of the adapter. I've seen people run three fans off of one adapter without a problem.

You don't actually need a 12v converter. My fan is running off of a 9v just fine (lower output though). Some people go to Walmart and buy a variable wall converter that allows them to choose the voltage (ie higher voltage when they want the fan to run stronger, lower when it's not necessary).

NeveSSL · #10 12/15/2007, 03:23 AM

Run them in parallel, though, as opposed to series so you don't lower the voltage.

That is, unless thats what you want to do.

Another option is if you can find a power supply from an old pc, and use that.

What does running them in parallel mean exactly? I have an idea but Im really not so good with electrical!

Thanks.

Series would be Neg to Pos to Neg to Pos - basicly just keep connecting them in a row.

Running them in parrellel you want to make sure that you have all the positives and all the negatives connected together, then connect that to the positive on the power supply and the negative on the power supply.

This is true, but they're rather large compared to other 12v sources (especially with switching powersupplies). Plus, most people don't need 10 amps to run a couple of fans... although you could find other things to do with the leftover amperage and the 5v leg, too...

If you do this, you'll probably want an AT power supply as opposed to ATX.

Good explanation draleigh.
