fan inside the Avid HD I/O (8 Analog I/O + 8 Digital) ?

[tobymusic]

It's basically the same fan they used in the 192 I/O:
COFAN F-8025M12BII, 12V DC, 33cfm and 29dB(a) noise.

It's easy to replace it with a quieter fan and that makes a big difference.

yep, the fans aren't that bad, but I'm about to swap them out in my new HD i/o's - go the extra mile and all that...

thanks

I found the following over at the avid forums:

"I just got the new HD i/o as well and the fan isn't bad but I want it more quiet as well. I opened it up and found the specs on the fan and how easy it would be to switch out. The fan it comes with is part# F-8025M12B II @ Axial Fans / 80x80x25 mm II and is rated at 29.9 dB at max speed not to mention it seems to rattle a bit! I found a fan SilenX Corporation - Effizio Quiet Fans
that has about the same flow rated at 15dB max speed which is WAY more quiet. They sell on newegg @ http://www.newegg.com/Product/Produc...82E16835226034
I think all that needs to be done is carefully take the connector off or splice in with the new fan since the one in the HD i/o has a 4 pin connector."

Heres a link to that thread: Need a new quieter fan to HD IO.. - Avid Audio Forums

I think this one might be the best option?

SilenX Corporation - Effizio Quiet Fans

If anyone has changed their fan please let us know how it went.

That one (EFX-08-12) is not pushing nearly enough air, so it's not a suitable replacement and the converter will run way hotter than it's designed to.

The one you linked to earlier (EFX-08-15) is a considerably better candidate at 32 cfm, and is still nearly 15dB quieter (assuming the measurement methods are comparable...) than the stock fan in the HD I/O.

Thanks for the part recommendation, guys!

[eddiestune]

thanks darksky, i haven't decided if to change the fan or not, yet, but if i do i'll post here on how it went.

My buddy next had me replace the fans in 3 blue digidesign interfaces. Made a considerable difference. I just cut the 2 wires and soldered plus shrink-rubbered the new ones in. Pretty easy, but you need to make sure the fans rotade the right way. If you mess up the polarity it runs backwards.

anyone else done this mod?

happiness?

I replied in the avid forum as well but the EFX-08-15 fan is still running great in my hd i/o 8x8x8 since last year. Very happy and easy to change out. And yes you want to make sure to get the EFX-08-15 since it has a CFM rating equivalent to the stock fan but is far more quiet and I can record acoustic guitars in the same room with it now. Maybe my stock fan was worse then some since it had a rattle as well. Note that you do have to switch or splice the connector on the new fan with the stock fans connector. I've attached a photo of the stock fan. It's in the bottom right and the connector is the white one at the top right.

is there a fan in the Avid (blue) Digital IO?

I dont have these interfaces..... are the fans supposed to pull air in, or out?

thanks

just did the hd io fan mod with a silenex fan as spoken about above. awesome. night and day. amazing. worth it if needed. not a plug and play mod. need to splice some wires but not hard. be blessed.

I just changed the fan inside an omni interface... but it seams like there is a rpm- oder current measurement because i get a fan error message after a minute.

edit: I did some testing, its not about current measurement (tried an parallel resistor to higher the current) but the tacho signal. I reconnected the orignal fan, stopped it, and after a minute I also got the fan failure.
