From an electronic engineers perspective the way Crg has described it is the way to go. I would leave existing connector on main board but cut wires about 2 " back. Then get fan of same size and dimensions and voltage rating etc and remove whatever connector is on that and solder to wires and heat shrink etc..

Fans have a little arrow which details the direction of airflow so it is important to put any new fan in the same way direction wise. (Is it sucking air in or blowing air out?)

I had the system too while working for Roland and it was quiet for me too. I think Zo is one of the unlucky ones that must have got a noisy one or it started out OK and got noisy quickly. One needs to measure the voltage on the fan because they can run at mains AC voltages or low DC voltages as well. And let us hope that it used a standard sort of voltage as well. It is a bit silly that an audio interface even needs a fan at all. They have packed too much inside that chassis. 

If you really wanted to do it right, you'd track down the actual pin connector that fits the existing plug, put them on the new fans wires and insert them into the existing plug. I can't even tell you what a headache that is going to turn into. You'd have to learn Japanese first.

I could not agree more

Zo, did you ever get around to try replacing the fan?

Now that the DAW workstation was moved to a separate equipment room I'm starting to hear the VS-700 fan ... sometimes louder than the voices in my head ;-)

nope i gave up , i have put some acoustic fom in the desk (under the rack ) it's still in dead silent ambience annoying ....keeping it  just for conveniance to the VS 700C monitors section .....i might talk about it to the the teck guru at the SAE ....as we also have one there ...

Hey just looked at the pictures I have of the vs700r and everything is written on the fan. Looks like 5V, 0.13A. The yellow wire must be to control speed. Someone with a screwdriver could easily remove the the top of the chassis and look directly, that's very easy to do and take 5 minutes.

One thing sure the fan is a San Ace 60 by Sanyo Sanki. The "60" in the name mean it's a 60 mm fan. http://db.sanyodenki.co.jp/product_db_e/coolingfan/dcfan/cooling_dcfan.html 

Could not find the Model 109R0605M4D041. Probably discountinued (LOOOOL)... or I just can't accurately read the numbers on the picture I have. 


The closest they have availible (according to the model's numbers) is this one: http://db.sanyodenki.co.jp/product_db_e/coolingfan/dcfan/dc_fan_detail.php?master_id=1755 

20 dba... honestly, every fans in my computer are louder than this but I can understand some have quieter place than me. 


Message sent to Sanyo asking for specs. Maybe they will answer....

Thanks Dyonight

That looks promising. If we can track down a plug and plug solution for a new fan, I'd definitely go for it. My VS-700R unit is more quiet than the (supposedly silent) new DAW workstation, but since I have moved the DAW to a separate equipment room, the VS-700 fan has become noticable. It's probably more than 20dBa; I might just have an older / different fan in there.

Well, to be honest ... it's not distracting when mixing, even at quite levels, but I enjoy the silence when I push the stop button and the VS-700 is the only thing that spoils the sound of silence ...

Haha! ok  I see!

I'll let you know if I discover more about it.

Damn... its a custom fan haha! I don't like at all "contacting" Roland... any one want to give it a shot?

Olivier,
This is a custom fan/proprietary part number. So you need to contact Roland for further support.
Thank you.
