Where to get a blower?

SysCrusher · 10-15-2004, 06:39 PM

Just as the title says. Looking for something to use in my own custom build case. Thinking of a car blower but unsure of the start up voltage/amps on these things. But that would fit the bill.

what size do you want?

I have one that's 10"x6"x7" and pushes 700CFM in free flow

redleader · 10-15-2004, 07:14 PM

^^ How much for something like that? I'm thinking of upgradeing the circulation in my house.

SysCrusher · 10-15-2004, 07:49 PM

LOL That's some serious air flow. I was thinking of something like this.

If I can put it on a dimmer switch or something would be great. More air flow the better though if I can still adjust the speed of it.

greenman100 · 10-15-2004, 07:56 PM

mine's 48VDC and runs all the way down to 12v

I'm thinking about selling it

How quiet is it at 12V? Compared to, say, a Vantec Stealth 80mm, Panaflo 80mm, or, uh, maybe a Wester Digital 7200rpm hard drive.

Just curious. I'm not particulary interested in buying it from you. Though you got a link to the manf. and model you have?

Thanks,

still makes some niuse at 12v, mostly the rushing of air-if I cap off the ends, it's pretty quiet

I'd say about like a single 80mm Panaflo H, but a lower frequency

DrCR · 10-15-2004, 11:15 PM

Cool, thanks!

Yeah, that's one another thing the blower have going for them. Whitenoise isn't anywhere near as bad as a quieter, but whiner noise IMHO.

Anyone seeing a problem running this off an extra psu?
http://www.surpluscenter.com/item.as...tname=electric

Someone got the lot on the last one. No more left.

What about running a 110volt on a dimmer switch? Is that possible and safe?

Dimmer will work fine. Theres obviously going to be a limit on how much it will slow things though. Generally AC motors have the speed determined by the frequency of the power. WHat the inductor does is lower current. So what'll happen is you'll starve the motor of power and force it to run slower then ideal. Eventually you won't have enough power to start it, but above that point it'll work as you'd expect.

THis is the one I originally wanted. Guess I'm to slow trying to figure out how to do this the best way before I spend the cash.

Don't some dimmers use the frequency? I remember using one of those flourescent bulbs in a dimmer and it wouldnt work because the dimmer itself would just flicker the thing off and on. The more you turned the dimmer up the faster that blink would go.

Dc blower that I looked at requires 9amps which might kill a psu over time. The 110 volt I could wire up along with my pump with ease.

9 amps isn't that much...
my 450w Powersupply puts out 22 Amps on the 12v line...
should handle the 9 amps fine i would think

that only leaves 13a

couple HDs, couple opticals, you're down to 10a

that's only 120w for the processor

better not run a presshot

possibly a 550 wat supply be enough?
myself i'm going to put my Fans and water pumps in an exteral box...
so i will have a dedicated powersupply for it...
only thing i'm worried about is that there will be no load on the 5 volt line...
I have read somewhere that this can cause the 12v line to drop? duno for shure..
guess i'll find out...

depends on how it was made. Those truepowers with the 3 dedicated lines will be ok. Any other will require a load on the 5v to get the full 12v. Why? I don't know. I did this to run my fans and without a load on the 5v I got only 10v out of the 12v. I used a small 5v fan mounted inside the psu and that got me just under 12v at 11.97v.

MadHacker · 10-25-2004, 04:39 PM

how many watts would i need on the 5 volt line?
would that be powersupply dependent question? or is it safe to say i would need X watts or X percentage of 12Volt power?

Your question is as good as mine. I used a small low powered flex psu for my fans so that small 5v fan did the trick for me. I never tried it on anything larger.

Dimmers are inductor based. A circuit that could change the frequency of a sizable AC current would most likely cost more then whatever you were trying to use it with. Its a lot more complicated then simply reduceing the current so that the motor isn't as effcient.

DrCR · 11-03-2004, 11:09 PM

Just FYI, but I've desided to go for 38mm thick AC axials instead. Seem to have the high pressue, low noise combination that I'm looking for, and for a given airflow they're quieter than a DC, for a given quietness they move more air.

The AC aspect is perfect too as I'll be using an Iwaki MD-20Z in a quasi-external rad box anyway.

A very good one? I know I would love to have a controller that delivered 50% power with no voltage applied.
