The Fun Little Gadget is Here! Cooling Fan Control Hub Feedback Request

[Fosi Audio]

Hello member!

We’d like to introduce our new fan control hub, which can support up to six 4-pin PWM fans with adjustable speeds, 12V trigger power sync, and temperature-based speed control. It’s a very nice solution for controlling external cooling fans in various setups and scenarios

Now, we’d love your feedback on the following:
1. What do you think of the hub? Does it meet your external heat dissipation needs?
2. What price would you expect for this product?
3. Besides the application of using the hub with Fosi products in the video, what other scenarios do you think it can be used in?
4. Would you prefer an aluminum alloy or transparent acrylic case?
5. With winter in the northern hemisphere, there may not be a big need, but in summer, would heat management for audio or electronics become a concern?

Thanks for your thoughts!

It would be nice if you sold the fans together as a kit and create some installing hardware for the fans eg magnets or suction etc.

Sure. Thanks for your input.

I am building a DIY version of something like this. Will be using a esp32 and will report the temperature via WiFi. Once well adjusted, I will leave it work alone.

The challenge here is where to place the temperature probe to have a meaningful adjustment. In my case, as the amp I will be cooling is also DIY, I can place several probes in key points close to the parts the heat up more, additionally, the fans will be part of the enclosure, blowing air to the inside. But something like what you are proposing, to be used with commercial amps.... Don't know, but doesn't seem reasonable to have people open their amps, and placing the probe outside.... Well, probably better than nothing but seems to me it might be a bit useless in most cases Vs just a fan in continuous operation.

Fair enough, I'm sure this will be of interest for some. Not my area, no issues (obviously)

Can I just make the point that no finished product you make should need cooling - please. Design in thermal management from the start.

Noctua (the manufacturer of one of the fans shown in the video) already makes some similar fan controllers:

I use one for my network rack. Perhaps you could explain the point of difference with your new product?

In the hope it might inspire others..

I mounted the controller in a blanking plate. Having two large fans running at low rpm keeps the temperatures in the rack down, which means that the smaller, noisier fans in the network equipment run at lower rpm. The overall noise level is reduced.

1. What do you think of the hub? Does it meet your external heat dissipation needs?

Yes, it has everything that I can think of.

2. What price would you expect for this product?

I am not familiar with the cooling gear market as I have not followed that for years although I would expect something like CAN ~$40-$50 if in a case.

3. Besides the application of using the hub with Fosi products in the video, what other scenarios do you think it can be used in?

It has cross application purposes for PC cooling.

4. Would you prefer an aluminum alloy or transparent acrylic case?

Black plastic would be good. It is unobtrusive and does not scratch other gear.

5. With winter in the northern hemisphere, there may not be a big need, but in summer, would heat management for audio or electronics become a concern?

Winter and summer both have cooling needs where I am in Canada.

Noctua sell the controller (which I have used in PCs) with a fan with a fancy shroud and stand... https://noctua.at/en/nv-fs1

It sells for £86 in the UK which is ridiculous for what it is: https://www.amazon.co.uk/Noctua-NV-FS1-Multi-Purpose-Award-Winning-NF-A12x25/dp/B0D179T54Q

I prefer to make my own USB driven, undervolted fans for improving airflow over things (you have to find fans that will start on 5V).

I also bought these fans a while back to cool my son's Xbox Series One S when kept shutting down due to overheating. They are fairly quiet and work well (solved the Xbox issue) and could be used for many other cooling purposes. https://www.amazon.co.uk/gp/product/B081RQRY3G
