I have a quiet CPU HSF Zalman CNPS6000-Cu. - 20db on quiet mode.

Soon to have 2 x Papst 8412NGL 80mm case fans - 12db

So you see I would like a psu fan to match!

Get a low RPM Panaflow fan. These are quiet and have good flow.

What's the frequency, Kenneth?

Old high end AT or XT power supplies often had them. Around 40CFM and wisper quiet.

Check the garbage can, people throw out high quality units frequently when the hardware they support becomes worthless.

Let me get this straight...

You are looking for an 80mm fan for your PSU that is quiet (25-35dBA?) and moves 35+CFM.

Also...

You are in the UK and need to buy from a UK supplier.

Is this correct?

If that which I posed above is correct.

Did you look at the <A HREF="http://www.kustompcs.co.uk/product.php?view=2514" target="_new">Thermaltake 80x80x25mm Fan</A>. It is the <A HREF="http://www.thermaltake.com/products/dcfan/8025.htm" target="_new">TT-8025A-2B</A>. It is a 80g, 3Pin, 37CFM, 30dBA, Axial fan. It comes with a 3 to 4 pin adapter. It is not a bad fan.

The <A HREF="http://www.kustompcs.co.uk/product.php?view=2528" target="_new">Papst 80mm fan</A> is oaky. It is the <A HREF="http://www.papst.de/pdf_dat_e/S17gb.pdf" target="_new">8412NGL</A>. It is a 12V, 19.4CFM, 12dBA, Sleeve Bearing, long life fan. It's faster brothers the 8412N and the 8412NH are better fans for what you are looking for.

As for the specs on your PSU.

What kind is it? Have you contacted the manufacturer for the CFM spec? If not, post what make and model it is and we can find a replacement for you.

That was definately a good idea. Most "air" noise is created by air flow getting disturbed by grills. That's why I took off my TT Volcano 7's grill. Made it a bit quieter and besides, I don't look inside my case very often just to "see the pretty HSF!" hehehe

The specs listed at quietpc.com look outrageous. It claims 40CFM for its 92mm fan at only 20 db. Be careful they aren't fooling you. I've found that fan cooling and noise ratings vary a lot because it depends on how far away you recorded the sound and also everyone already knows that a lot of thermal sensors are inaccurate (like the ones from asus) and often when measured they are too far away from the heat source (like the ones for the athlons)

I sent a request out to them for specs on the existing fan so I will update you when I get an answer. I'll post suitable fans once I get the specs. I hope to have an answer for you soon.

I got a response from a Carlo Hong. This is what he said,

Quote:
How much do you want to spend? We can go with a low-tech solution that you will change all your fan to a sleve berring fan, that will keep them quiet. Ball barring product a higher pitch sound.. Or We can always go with the water cooling solution. An quiet internal water pump... Let me know what you think and I will see what else I can do for
you.

Have a great day!

Carlo



As you can see it was vague so I sent him another message. Sounds as if he wants to sell something.

Since I don't know what is the room temperature of the system where is located, it will be hard for me to say. Sleeve Berring fan produce less noice compare to ball baring and CPU Fan. In order for system to stay cool, you want to creat a good air flow. Ideally you will have fan that suck cool air into the system and fan that suck hot air
out of the system. That will be why system used to be able to mount fan on the front of the case and also on the back. The panasonic one is nice, but I don't know how much noise it produce.

Have a great day!


I posted the Panasonic <A HREF="http://www.panasonic.com/industrial/appliance/pdf/fba09..." target="_new">FBA09A12L</A>. It is a 92mm, 27dBA, 48CFM or (1.21mm3/min), 2100RPM fan at 12V. Or you could use the FBA09A24L which is the 24V fan.

If he says it is good to go than I would take it to be an okay spec.

Im not sure if Carlo Hong undersands that you are asking for a PSU fan, it sounds as tho he is suggesting quiet cooling for a PC generally.

Also, the fan you suggest, the Panasonic FBA09A12L - is a 92mm fan. Will that fit in a PSU that is currently using a 80mm fan??

I've also been doing some looking of my own (now just letting u do all the work :)  )

So far suitable fans:

<A HREF="http://www.tekheads.co.uk/products.php?view=product&pro..." target="_new"> Thermaltake 80mm Smart Case Fan </A>

and

<A HREF="http://www.tekheads.co.uk/products.php?view=product&pro..." target="_new"> Papst 8412 NGM </A>

The thermaltake would be able to handle any heat the PSU decided to throw at it, but the Papst is a little quieter.

All comments welcome :)

I don't know if it's just mine but my panaflos caused a fair amount of vibration. So you might want to get something to absorb the vibration. It could just be mine, however I haven't used them for very long.
June 3, 2002 6:26:06 PM

I did not realize it was a 80mm fan and not a 92mm.

Some use one or the other or both.

I suggest the <A HREF="http://www.papst.de/pdf_dat_e/S17gb.pdf" target="_new">Pspst</A>. It is a good fan. I highly doubt that you will need more than 35 CFM for a PSU.

As for Carlo Hong...???

I don't know what he was thinking. Maybe he had to translate my message in Babelfish?

How tight did you screw them down? You could go to the hardware store and get rubber washers to eliminate that vibration if you tightened the screws down all the way.
