PWM controller for 12V fan with temperature sensor for LAN 300x700x150 cabinet

Hello,
i am planning to build a LAN box in which I would like to house all the network control devices in a detached house.
I envisage e.g:
- pOE power supply for the AP on the façade
- wifi router
- robust switch
- possible neostrada modem
I would like to install everything in a metal cabinet, size W300xH600-700xD150mm. The cabinet is a bit large, but I have the space and do not want to worry about lack of space later.

All these devices like to get a bit warm and hence I thought of a fan/fans to cool the box. Ideally I would like to do this with 12V computer fans of e.g. 100-120mm diameter but necessarily with speed control in relation to temperature as is done in the computer case. I am therefore looking for a cheap speed controller (preferably PWM) with a temperature sensor.

Thank you in advance for any leads to such devices. Unfortunately, I have not been able to find anything similar for a reasonable price.

None of these devices overheat enough to worry about overheating and putting a wifi router in a metal case is unwise to say the least

Here you go.

I have a 'gadgeteer' friend who has access to by no means low-budget equipment. In a not so small cabinet (about 25x25x30cm) he has just two devices (neostrada+router) and in the summer he has to open the cabinet because his router hangs up.

Of course, the wifi router will have antennas outside the cabinet - I just happen to have one Netgear with the ability to create 3 wifi subnets and am wondering where to squeeze it in.

I am looking for a cabinet to be built in the wall, in the cabinet there will be several devices (among others: modem, switch or wifi router + power supplies). i am looking for a cabinet to build in the wall, there will be several devices in the cabinet (including a modem, switch or wifi router + power supplies), the cabinet should be plastic (allow WiFi - the router has internal built-in antennas, moreover external antennas leading out of the cabinet is no decoration and tempt children/dogs/cats ) and be quite shallow (preferably not more than 8 cm forged into the wall, and better still less), and have considerable "flat" dimensions (I would give the equipment "flat", currently I have a built-in cabinet about 12x30 cm and it is too small, besides the current built-in cabinet or rather a large rectangular box with a lid has inside an awful lot of some reinforcing "humps", which strongly interfere with the arrangement of equipment and cables).

What keywords should I search for (manufacturer, name)?

As for ventilation it's a troublesome matter, you can install some holes in the lid with a computer type fan, but then noise appears and it will be disfiguring (the cabinet lid will be in view unfortunately).

The developer brought all the "utilities" (cable, net, telephone) to the area around the door in the hallway, which currently fits like a fist to the nose (the utilities distributed from the under-floor cabinet "in the star" cannot be easily moved without forging in the plaster).

Alternatively, I could go for a wall-mounted mini-rack that can be partially recessed into the wall (can you suggest such a solution?).
The alternative for me is to forge one or two peszes into the plaster for a couple of metres to a large wardrobe cupboard with plenty of space, only try to tell my spouse about the wall ripping

Dipol from Krakow used to promote their own cabling concept, for which they proposed a "central" cabinet - under the name domnet
Look for them

Alternatively, Pulsar manufactures enclosures for control panels and accessories. Both surface and flush mounted versions. Many different sizes, disadvantage that they are metal.

Metal is not an option (WiFi shielding, DECT shielding, Bluetooth shielding).

Perhaps after some time you will come to the conclusion that it is worth giving even the smallest rack a place and that's it
There are also so-called vertical, 19 inch, 2U or 3U racks, after a small modification you can also fit a shelf and an inverted patchpanel there

It happened to fit a lot of things, DVR, router, restarter, panel, switch, etc
An external antenna, brought out from the casing is not a big price to pay for this solution, moreover it is in accordance with the physics of propagation - better this way than counting on proper radiation of an antenna placed in a niche such as a cabinet, even a non-metallic one

Appetite grows with eating, I know from experience that every cabinet quickly becomes "too small"

At Dipol's, only one size and metal (so it will shield WiFi), well, and frankly expensive.
In the meantime I checked that there is still a polystyrene slab in the wall behind my current box (the builders left space in the wall for the electricians this way), so I will easily be able to give a box deeper than the current 6 cm (well, not some terribly deep one, but let's say up to 12 cm deep into the wall).
It's a pity that there's not enough depth in the wall (because of the cables sticking out at the back!) to place the equipment normally, i.e. horizontally.
Another issue is the difficulty of cooling in a box built into the wall, some kind of openwork front should be provided.
I can think of an elegant speaker front
