12v DC Brushless Cooling Fans

[Growly Lytes]

Im trying to track down where to find these replacement fans for my Poweramp.They are...
120m x 120m x 38m
12v DC 0.6a
Company - Innovative
I really cannot find even one of these fans anywhere To find the same size & specs has proven hard to find also through another brand.
There bigger than usaul Poweramp fans , it comes out of a 3U Poweramp.

have you tryed a computer case fan?

Newark came through for me a couple of years ago when I replaced the single noisy fan in my Genz ML200 with two quiet ones.

Just a thought.

Check the data sheet. It even looks identical

I've probably got some in my junk pile that you could have but shipping them would cost more than they're worth. Very likely you can pick up a couple for free out of dead PCs.

dead pcs wont have 120x38 mm, thats a high end cooling fan in the pc world
they are sold online however, sanyo denki fans are the best that ther are in terms of static pressure and airflow per decibel

Yep shes a biggy`120m x 120m x 38m a little big for a p.c i think.
This company doesnt have a website (Innovative) & thats the biggest hassle because i would contact them direct but i cant find them.They must be under another name !

well strictly speaking, a lot of computer fans go up to even 230+mm. you can even check out www.newegg.com under the case fans section. plenty to choose from. unless you already found some replacements. good luck.

[Jerrold Tiers]

120mm / 4.7 inch square is a common fan size.

Fans do differ by air flow, and especially by airflow vs "static pressure", which amounts to backpressure from friction.

A lot of fans move plenty of air in free air, but fail to move it through heatsinks due to backpressure.

I don't know that brand, and Google does not find a good link. The one I found was dead.

Lots of fans have that exact same part number, but many are not the same as that fan, showing different current, 0.4A instead of 0.6A, for instance.

[tealrex]

The one in the link i posted is 120x120x38 12vdc brushless draws .5 amp probably the closest your going to get Check the data sheet specs

[Growly Lytes]

So what would happen if i was to use an identical fan except it was 0.5a instead of 0.6 ? Would that be usable or dangerous ? I mean its a . difference ?

Some choices

[tealrex]

Using one that draws more amps than the original could burn up what ever circuit feeds the fan with juice. Running one without enough amp draw might not have the balls to move enough air. So you just have to get as close as you can

[UncleFluffy]

As Jerrold Tiers points out, even fans with the same size + power can vary in air-moving performance. IME, you're going to have to grab the best one you can find and keep an eye on things to see how it works out - no cranking everything up to 11 for a few weeks until you're confident its up to the job.

One other thought - did you contact the amp manufacturer and ask if they can supply a spare?

Yes & they wont have any for about 2-3 weeks coming from China i think.They just rang me & said they have got a replacement but its 2nd hand & its the same make & model but 2nd hand , what should i do it has warranty of about 5 months to go ?
Should i go for the ysed one & then get a new one when they come ? Im not sure they will give me another one if im using the 2nd hand one & its working ?
Any help please im lost & also i have more questions about Poweramps !

I'm not really sure where your location is, but if you're close to Houston, TX there's a couple of places where you can get lots of different fans, ranging from cpu-sized to keep-your-hands-off-sized, and from 5 volts dc to 220 vac and everything in between. It's called Electronic Parts Outlet, or EPO for short. Do a search within your city for electronic stores and you might find something helpful.
As for the specs, try to stay within the .6A rating (same or less); you might not get the same air flow as with the original one if you use a smaller one [might --remember there are different efficiencies] but anything is better than nothing. Too bad you don't have the CFM figure for the original one, and you might not know if the one you get is good enough until you install it (unless you get one exactly as the OEM), buy as someone mentioned above, go easy when you first install it and monitor the amp behavior...
Wait.
I just saw your comment about them offering to get you a 2nd hand replacement; if it is under warranty will you get it for free? Anyway, I would wait the 2 to 3 weeks (provided this is possible) and get the new one.
If you really need to use the amp in the meantime and have $ to spare, you might try getting a 110v (or 220, depending on your local setting) and connect it directly to the power line (inside the amp, of course). The fan would be on all the time the cord is plugged to the wall, but the amp will be safe (and you won't have to worry about other things)
I might go on and on about asking you where is the power coming for this OEM fan and if there is really a .6amp restriction... but I think that's enough for now.
So, in short:
1 Try to get the replacement fan from them (under warranty, that is.) ... too bad it's coming from China.
2 If you really, really need to use the amp in the mean time try getting one that has the same voltage as your wall outlet wherever you live (thus you don't have to worry about how many amps it is)
3 In case you're not getting it for free, try to find one that best matches the original. And again, I really would like to know if there really is a .6 amp restriction for the fan, otherwise your selection would open a lot of different options.
4 Whatever you do, get a fan; electronic components hate heat (they die). Any fan is better than no fan.
I'm curious about what happened to the original fan that you need to replace... in more than 35 years of working with different electronic equipment I can't remember ever having to replace a fan... maybe I've been in the wrong place at the wrong time to see that happen, but I've work in pro audio installation and design, iron foundry control design, HV distribution and maintenance, consumer electronics repair; and as hard as I try I can't remember not even one instance...

Well, I hope everything works out well for you.

try newegg . com
performance pcs . com
directron
frozen cpu
all those places have all kinda different 12v fans ones with lights ones without lights. ones that have a really high ccms. it doesn't have to be a deep fan like the one you have it could be one of the shorter ones. I think the deeper fan maybe better I think they will produce a higher static pressure inside the chamber. Just get one with a high ccm. somewhere around 114ccm

most local computer stores and probably even best buy and maybe even office max might have them to where you could get a quick replacement. I agree with the above poster that any fan is better than no fan. Most fans that size draw .5 amps or less.

Alright il try to answer most...
They are going to give me another one 2nd hand used one `for free` under warranty now if i want it or i have to wait 2 weeks for a new one brand new !! The 2nd hand one is the exact same fan as mine same make & model !
I sent the amp to the factory for a check up because i could hear a buzz but it was something else & the amp was fine.When they sent it back to me the fan was dangling inside i could hear it hitting the walls of the amp.It was broken right off the chassis frame look........

[Growly Lytes]

Im going to try to maybe (this may be stupid) & fix this with some liquid nails.Let it set for a few days & give it a whirl before i put it in the amp again.Im not very sure this will work but that liquid nails is so strong ive glued concrete together with that stuff.
But back to the question should i go for the 2nd hand one or wait for the new one 2 or 3weeks , im covered by warranty & i wont have to pay for neither of them but what would you do ?
2nd hand in working condition
A New One In 2-3 weeks

[UncleFluffy]

I'd ask for the 2nd hand one + a spec sheet so that you're not dependent on them any more.
