It's perfect. My biggest problem currently is that the USB fans I use to cool my V3 monos are audible from my listening seat even with them set to low. If I could slow them down more, I could get them quiet enough not to hear them. The amps don't need much airflow to keep them cool.
Great idea @ Fosi Audio, Can you please make it a no noise, all black with aluminum casing except for the propeller make it an orange one for aesthetic looks to goes along with the ZA3 / ZD3. Good luck with your works.
It needs to come with a temperature sensor that can be attached to the housing of the amplifier. So it will only power on when necessary. Also variable fan speed depending on temperature.
If heat is ok and won’t hurt the V3 Monos, I’m not sure why any of this is necessary? Instead of fans and controllers, a much more “elegant” solution would be to attach heat sinks to the sides of the Monos; yes, cover the holes which really don’t do much, with long strips of heat sink. This would add to the size of the amplifier, but would also passively cool it with no noise (audible or electrical).
less heat = lower distortion & more power, opamps and bigger power supplies are great upgrades but IMO the biggest gains will be found in better thermal solutions
@@phillipmorris9847I don’t disagree. My point was related to how Fosi marketed their cooling strategy for these amps, and all of a sudden it seems to be a concern. An elaborate cooling system like the one proposed here will add considerable cost and complexity to a product line which is supposed to be about simplicity and small form factor.
@@superspeeder Every user concern is also our concern. Rest assured, the thermal design of the V3 Mono and our other amplifiers is sound, and this product is not intended to compensate for any cooling deficiencies. We designed this fan hub, along with other products such as fans and cooling racks, in response to user requests. We noticed that our amplifier products are used in a wide variety of settings, some of which require enhanced ventilation and cooling. Therefore, our R&D team began developing new products to meet these needs.
Thanks for your comment. We are introducing this hub and the fans for users with various heat dissipation needs, not just for audio equipment but also for other electronic devices. There would be no problem with the heat dissipation of our amplifiers when they are placed where heat doesn't tend to build up. But when users have, say, 5-6 V3 Monoblocks in the setup, it would be better to generate some airflow to take away some heat.
If my equipment (of such size and power) requires active cooling for additional assurance or to maintain its performance, then my thought would be.... something is very wrong with this company's product, design wise. Get that sink in for a while. Dont get me wrong Fosi, my BT20A is still works for its purpose after all these years albeit will produce "pop" when On/Off most of the time.
Please rest assured, the thermal design of all our products undergoes rigorous testing to ensure safe and long-lasting use. We develop new products to meet more diverse user needs. Of course, fan hubs like the one in this video can also be used in other scenarios requiring ventilation and cooling, not just for amplifiers.

In the professional field, active cooling is practically included in all devices. In the domestic field, in many cases it may not be necessary, but depending on the location of the device, it may not have adequate natural cooling or when intensive use is required for many hours. This proposal is very interesting because users interested in working with a controlled working temperature can configure the set depending on their needs. The TPA3255 chip installed in a V3 - ZA3 chassis may seem to work at a high temperature because it can practically be touched with the hand when connected to the chassis. This chip in a conventional 435 mm wide chassis would work at the same temperature but its working temperature could not really be appreciated. Greetings
@@fosiaudio Again, please don't get me wrong. I'm not dropping down comment to downgrade your products be it the one I'm using or those that you are promoting. It was merely just a view "IF...and IF" I never knew who/what this Fosi Audio is, from a new user/comer/potential-buyer perspective. My point is it gives a skew impression when a good audio manufacturer introduce a product with their brand name on that wasn't inline with their core products line-up, as if there is a production mismatch along the line or a self-destruct thinking. Leave the fan controller hub to those computer parts manufacturer. None of your audio product line-up should ever require it to operate in any environment. Having an opposite view than mine is fine, I don't gain or lose anything from it. Just words from end-consumer's perspective.
Nice. I already bought the current option.
Would like to see the acrylic pedestal ( with matching fan holes ) as an optional
Thank you!
I had one of these for a PC build about 15 years ago, installs in the HDD bay
Nice!

I think this fan control hub can be the choice. It can fine adjust the fan speed.
Thanks for the comment! The noise could be distracting sometimes, so adjustable speed seems a good way to go.😉

Thank you for your suggestions!
I was thinking of making something like this myself but with fixed low speed fans. This looks to be just what I need. Please make it available.
Thank you for putting trust in us! We will keep the community posted!
good idea yes I wouold like 1 0r 3

Thanks, so far our engineers have made the right choices then😁

@@superspeederI think its just a upgrade option for there products that they can make and offer rather than a concern.

when can we purchase one of these...
Sorry for making this so long.😭 We would still need to collect more user suggestions. Will keep the community updated!
Please sell the rack as well
Fosi pls create a wifi streamer with decent screen, coax&opt out,etc...
We also hope to put this one on our to-do list!😉
Why do you say "Except for audio equipment"?
Sincerest apologies. It should be "besides".
No fans in the listening room. Ever.
