blower worth it?

PetDMC · 11-17-2002, 09:21 AM

i was thinking of putting a blower on my BMW Heatercore, i found one the fits perfectly on it.

it's 460 cfm @ max but the thing cost 34 USD and the shipping it $40

that's 77.xx total, but since i'm in Canada it's $120 and the UPS turds want also $30-$40.

so the question is, should i buy it or just go with 6 92mm (3 on each side of the core)

MadDogMe · 11-17-2002, 09:42 AM

I'd use 2 120mm fans with a shroud, all the 92mm I know of have poor (comparitivly) CFM's (40-50) plus you'll get less noise with two 120's

. I use 2x 92mm 47CFM panaflos at the moment, but I'll relagate them to 7V PSU as soon as my 120 arrive

. you also get a 'harmonic resonance' discord with multiple fans together at max speed, run them slower (7V or fanbus) to avoid this...

PS, push/pull fan setups yeild very little (like 1DegC) over normal pull/suck setups, worth the noise?...

PetDMC · 11-17-2002, 09:53 AM

for me to shroud on 2 120mm i'd have to V shape the shroud, cuz i do have 2 comair rotrons but they are LOUD @ max

and i would rather get a blower

MadDogMe · 11-17-2002, 10:18 AM

Have you considered 2x175mm fans?(AC or DC), if you don't want to mess with a shroud,(there's nothing wrong with making the sides 'funnel' shaped though), or even considered a new heatercore with a better fit?, I doubt the BMW one is copper?...

That seems a lot of £$% for a blower that's all :shrug: ...

I wish PC/Cooling/OverClocking shops would start selling 175mm(172?) fans. alot of HC's are perfect sized for them, whereas 120's just dont quite fit without sharp angled / * \ sides...

UnloadeD · 11-17-2002, 10:38 AM

I'm looking at getting one of these fans:
https://www.jameco.com/cgi-bin/ncomm...s=503;533;798;
Its 24v but spec sheet says it'll run on 12v-28v

i have one of those, but it's 300 CFM and it's going on the side of my case

^ thats what the HC looks like (kinda of

)

PetDMC · 11-21-2002, 03:02 PM

oh well, i caved

i bought the blower

now which side of the core should i put it on? the side with the connectors or the side with out?

airspirit · 11-21-2002, 05:47 PM

Doesn't matter. Just make sure the fan is pulling with some shroud space inbetween the core and the fan.

there's a reason they call them blower fans

i'm gonna put a gaskit between the blower and the core

click for pic

BTW my HC has a housing for it

(BMW HC are the bomb) once i get the blower i'll try and get some pics up

airspirit · 11-21-2002, 06:17 PM

Oops, I should have caught that. Sorry. I was thinking 120mm/92mm fans still. Ignore me.

it's all good man

got a great deal on the blower too
$33.15 USD

linky scroll down to the AO Smith blowers

airspirit · 11-22-2002, 10:02 AM

That looks like it'll be one loud sumb!tch. I wouldn't be suprised if that was rated at 58-59 dB, but then you'll be hard pressed to find a blower that doesn't exceed 50 dB.

PetDMC · 12-11-2002, 10:23 AM

w00t!!!!

i got the blower today, and damn this thing rocks, its a beast!

this thing is industral

i haven't hooked it up yet but i turned it with my hand and it moves lotsa air, even if its 2-6rpm
felt like 20-40CFM

if i remember corectly the pressure it like 60-80 or something

the only thing that sux is that the flange is about an 1" too small, so i guess i have to shroud for it

bigben2k · 12-11-2002, 10:39 AM

That's great!

Do you have any dimensions?
What was the total, with shipping?
If / how do you plan to reduce the speed/noise?

| 24.5cm

i'll try and get a pic of it tomorrow

the blower itself was $34USD i think and shipping was $36USD
it weights 11lbs

i'm still working on the controller

the motor specs:
A.O. Smith
1/20HP, 1PH, 115V, 60Hz, 2.45A
1550 RPM, CWLE, TP, INS, CL "B", SPEED TWO

bigben2k · 12-11-2002, 03:23 PM

That's about 8 by 10 inches

PetDMC · 12-11-2002, 03:30 PM

yup, nicely fits my HC, just a inch or so off

still have to make a shroud

oh and about the speed, since it two speed it should be fine

i'm gonna test it tomorrow on low and high

BTW the pic is kinda misleading, its not as long

lukasz70 · 12-12-2002, 11:38 AM

BMW HC for 20Cdn

PetDMC · 12-12-2002, 03:42 PM

no worries man, i can't even write

anyway, i did some more testing on the blower and i hooked up the second speed wire (since it's two speed

) and to my surprise, it runs about half the full speed

no need for a for a controller

this was a great deal for this blower, if you could use it i would so buy it in a heart beat
