Fan count
Four — stated in the title as a fan panel with four fans for a floor-standing server cabinet
Fan size
Not published on the listing — no diameter and no frame dimension appears in any bullet. The second calls the unit both strong and quiet without measuring either
Stated airflow
Not published on the listing — no figure appears. The first bullet says the unit secures optimal air circulation in a 19-inch cabinet, protects the equipment and increases its service life, all without a number
Airflow unit
Not published on the listing, because no airflow figure is given for a unit to attach to
Stated noise level
Not published on the listing — the second bullet describes the unit as quiet and no decibel figure and no measuring distance follows it
Roof or rack-mount format
Not published on the listing as one or the other — the title names a fan panel for a 19-inch network cabinet and a floor-standing server cabinet, and no bullet says whether it sits in the roof or on the profile rails
Rack units occupied
Not published on the listing — no rack unit figure appears anywhere, and the mounting format that would imply one is not stated either
Airflow direction
Not published on the listing — nothing says which way the fans push, and nothing says whether they can be turned in their frame
Thermostat or speed control
A thermostat with a digital temperature display, stated in the title and in the second and third bullets, with thresholds settable from -40 to 50 degrees according to the fourth. It is the widest threshold range published on this shelf and the only one given as a span
Power connection
Not published on the listing — no lead, inlet, voltage or plug is named. The fifth bullet offers a 36-month warranty instead

On the listing

A fan panel with four fans for a 19-inch floor-standing server cabinet, with a thermostat, temperature control, a built-in fuse and a digital temperature display; a stated purpose of securing optimal air circulation in a 19-inch network cabinet, protecting the equipment and increasing its service life; a description of the unit as both strong and quiet, with the thermostat and display giving control inside the cabinet; thresholds settable from -40 to 50 degrees; and a 36-month warranty.

Minus forty to fifty

Two units on this shelf publish the range their thermostat can be set across. This one publishes the wider by a long way.

Ninety degrees of adjustment. Most of it is theoretical — nothing about a network cabinet involves cooling at minus forty — and the span still tells you something worth having.

A thermostat is only as useful as its resolution in the region that matters, which for a cabinet is between roughly twenty-five and forty degrees. That is where the difference between fans running all night and fans running under load actually lives. A controller offering ninety degrees of range is a general-purpose part, which usually means fine adjustment where it counts rather than three coarse positions.

Four of the seven listings on this shelf carry a thermostat. Two publish anything about its behaviour. This is the more generous of the two.

The fuse in the title

The second thing worth stopping on is a component that appears once in this entire hub.

A built-in fuse, named in the title.

A fan panel is a mains device living inside a metal cabinet surrounded by network equipment, and the interesting failure is not a fan that stops turning. A fuse inside the unit means a fault in the panel takes the panel out of service rather than tripping whatever feeds the cabinet.

None of the other six listings on this shelf mentions one, which is not the same as their not having one. It is simply not a part anybody thinks to advertise, and this listing did.

Strong and quiet, in words

Then the page runs out of numbers.

The second bullet says the fan is both strong and quiet. There is no airflow figure and no decibel figure anywhere on the listing to attach to either half of that sentence.

Two units on this shelf publish an airflow and two publish a noise level. Those are the two figures a cooling panel is actually chosen on, and the whole argument for one product over another lives in them. Here they are adjectives, on a four-fan panel in the middle of this shelf by price.

What is not said about fitting it

The title names a 19-inch network cabinet and a floor-standing server cabinet, and no bullet says how the panel attaches to either.

Roof module or rail-mounted panel — those are the two arrangements on this shelf and they need entirely different provisions in the cabinet. Nothing here says which this is, no rack unit figure appears, and no dimension is published.

The power arrangement has the same silence around it: no voltage, no lead, no plug.

Before ordering

Ask how it mounts and what it plugs into, because neither is on the page and both decide whether it can be installed. Ask for an airflow figure if you are comparing it with anything. And if the cabinet lives near people, ask what quiet means in decibels — two listings on this shelf will answer that without being asked.

More rack cooling fans

  • Intellinet black 19-inch 1U cooling unit with two fans mounted on rack rails

    INTELLINET NETWORK SOLUTIONS 19-inch 1U rail-mounted unit, two fans, 95–115 CFM, 44–49 dB/A, IEC 297-3

    The most measured product on this shelf: airflow, fan speed and noise level all printed as ranges, with a standard cited by number and a frame thickness in millimetres.

    Fan count
    Two — stated in the title, which describes a cooling unit with two fans for 19-inch cabinets, mounted on the profile rails
    Fan size
    Not published on the listing — no diameter and no frame dimension appears. The fourth bullet gives a fan speed of 2700 to 3100 rpm instead, which describes how fast they turn and not how big they are
    Stated airflow
    95 to 115 CFM — stated in the third bullet as the air throughput. It is one of only two airflow figures on this shelf, and the range is given rather than a single number
    Airflow unit
    Cubic feet per minute — the third bullet quotes CFM. The other airflow figure on this shelf is in cubic metres, per minute and per hour, so the two cannot be compared without converting one of them
    Stated noise level
    44 to 49 dB/A — stated in the fifth bullet. The measuring distance is not published on the listing, which is the figure a decibel number needs to be comparable
    Roof or rack-mount format
    Rack-mounted — stated in the title as a unit for mounting on the profile rails of a 19-inch cabinet, at one rack unit
    Rack units occupied
    One — stated in the title
    Airflow direction
    Not published on the listing — nothing says which way the fans push, and nothing says whether they can be turned in their frame. None of the seven listings on this shelf publishes a direction
    Thermostat or speed control
    Not published on the listing — no thermostat, no speed switch and no temperature sensor is named in any of the seven bullets. Four of the seven units on this shelf have one and this is one of the three that do not
    Power connection
    220 to 240 V at 50 to 60 Hz — stated in the sixth bullet as the operating voltage. No lead, inlet or plug type is published

    • Airflow, fan speed and noise all published as ranges, which no other unit here manages
    • Cites IEC 297-3 by number rather than claiming rack compatibility in general terms
    • No thermostat and no speed control, so the fans run whenever they are powered

    Best for: A cabinet needing continuous ventilation with a known air throughput, in a room where 44 to 49 decibels is acceptable all day.

  • kenable black 19-inch 1U rack fan tray with two fans and an LCD thermostat display

    kenable 19-inch 1U fan tray, two fans, digital thermostat with LCD, 180 mm mounting depth

    The only cooling unit on this shelf with a display on the front, showing the cabinet temperature and the fan setting, and the only one that names the length of the mains lead in the box.

    Fan count
    Two — stated in the fourth bullet, which describes two powerful fans providing air circulation in a 19-inch rack
    Fan size
    Not published on the listing — no diameter and no frame dimension appears. The fourth bullet calls the fans powerful and gives no measurement
    Stated airflow
    Not published on the listing — no figure appears in any bullet. The fourth describes optimal air circulation and effective cooling of IT and network equipment without quantifying either
    Airflow unit
    Not published on the listing, because no airflow figure is given. Two listings on this shelf publish one and they use different units from each other
    Stated noise level
    Not published on the listing — no decibel figure and no measuring distance appears. The fans are described as powerful rather than as quiet
    Roof or rack-mount format
    Rack-mounted — stated in the title as a 48.3 cm 19-inch 1U unit, and in the third bullet as a standard rack mounting with the fixing ears supplied, for data and communication cabinets
    Rack units occupied
    One — stated in the title and in the third bullet, which also gives a mounting depth of 180 mm
    Airflow direction
    Not published on the listing — the title and the fourth bullet describe a two-way fan system, which is not explained anywhere. Whether that names two fans, two directions or a reversible arrangement is not stated, and nothing says which way the air moves
    Thermostat or speed control
    A built-in thermostat switching the fans on and off automatically as the temperature crosses a set threshold, stated in the first bullet, with a large LCD display in the second for monitoring the current temperature and the fan settings. The threshold range is not published on the listing
    Power connection
    A 1.8 m IEC mains lead, included — stated in the fifth bullet as part of a complete set ready for immediate installation

    • A display showing the current cabinet temperature, which no other unit here offers
    • The mains lead is in the box and its length is printed
    • The two-way fan system is named twice and explained nowhere

    Best for: A rack where somebody wants to see the cabinet temperature without opening the door, and can spare a rack unit for it.

  • Koscom Connect black roof fan unit with two fans for a network cabinet

    KOSCOM CONNECT roof fan unit, two fans, switch and thermostat

    The cheapest cooling unit in this hub and the least documented product on any shelf of this site: two fans, a switch and a thermostat named in the title, and one sentence of description behind them.

    Fan count
    Two — stated in the title. No bullet repeats or expands on it
    Fan size
    Not published on the listing — no diameter, no frame dimension and no fan model appears. The single bullet calls the fans powerful and stops there
    Stated airflow
    Not published on the listing — no figure of any kind appears. The single bullet says the unit provides optimal air circulation in a network or server cabinet, which is a claim rather than a measurement
    Airflow unit
    Not published on the listing, because no airflow figure is given for a unit to attach to. Two of the seven listings on this shelf publish a figure, one in cubic feet per minute and one in cubic metres
    Stated noise level
    Not published on the listing — no decibel figure and no measuring distance appears anywhere
    Roof or rack-mount format
    Roof — stated in the title as a roof fan unit for a network cabinet, and repeated in the single bullet
    Rack units occupied
    Not published on the listing — a roof unit sits in the cabinet top rather than on the rails, and the page never says so or gives any mounting dimension
    Airflow direction
    Not published on the listing — nothing says which way the fans push, and nothing says whether they can be reversed in their frame
    Thermostat or speed control
    A switch and a thermostat — both named in the title. No threshold range, no display and no control detail is published
    Power connection
    Not published on the listing — no lead, no inlet, no voltage and no plug is named

    StarTech two 1U vented cantilever shelves, 25 cm deep, 20 kg each, tested at 1.5 times load

    The only shelf here sold in pairs and the only one whose maker states a test margin above the rating, at a quarter of a metre deep and twenty kilograms a tray.

    Rack units
    One each — stated in the title and in the first bullet, which describes two 1U vented cantilever rack shelves in a set
    Mounting depth
    25 cm — stated in the title. No minimum cabinet depth is named, and no adjustment range appears
    Cantilever or four-post support
    Cantilever — stated in the title and in the first bullet, and detailed in the fourth as SPCC cold-rolled steel with cantilever front mounting. It is one of only two listings on this shelf to name its support arrangement in words
    Stated load rating
    Up to 20 kg per shelf — stated in the title and in the fourth bullet, which adds that the shelves are tested at one and a half times that load. The test is the maker’s statement and no test document is named
    Vented or solid surface
    Vented — stated in the title and in the third bullet, which describes a perforated 1U tray supporting even airflow and reducing hot spots under servers or audio-visual equipment
    Sliding or fixed
    Fixed — the fourth bullet describes cantilever front mounting, and no bullet mentions runners or any pull-out action
    Usable surface dimensions
    Not published on the listing — 25 cm is given as the depth in the title and no width or surface figure appears in any of the five bullets

  • Stalflex black perforated 19-inch 1U rack shelf

    STALFLEX 19-inch 1U shelf, rear fixing, variable depth, 25 kg

    A 25 kg perforated shelf sold on a rear fixing and a variable depth, with five bullets of description and not one measurement among them.

    Rack units
    One — stated in the title and in the second bullet, which calls the standard 1U and 19-inch format a guarantee of secure mounting
    Mounting depth
    Not published in the title or in any bullet — the title says variable depth and stops there. The manufacturer reference recorded for this listing reads 150 mm, which is a catalogue string rather than a published specification, and no bullet confirms it
    Cantilever or four-post support
    Neither is named — the title states that the fixing is at the rear, which is not the arrangement either of the two named terms describes. No post count and no front-flange description appears in any bullet
    Stated load rating
    25 kg — stated in the title as the carrying capacity. It sits above three of the fixed shelves on this shelf and well below the four-post one
    Vented or solid surface
    Vented — the first and fourth bullets both describe a perforated shelf, credited with improving air circulation and with preventing equipment overheating
    Sliding or fixed
    Not published on the listing — no bullet says whether the shelf is bolted in place or runs on any kind of slide. The fourth mentions mounting equipment to it with cable ties to stop accidental slipping, which is about the equipment rather than the shelf
    Usable surface dimensions
    Not published on the listing — no width, no depth and no surface figure appears in the title or in any of the five bullets
    Fixings supplied
    Not published on the listing — no screws, no cage nuts and no washers are listed. The second bullet says the standard format guarantees secure mounting and names no hardware

  • ARLI shielded RJ45 crimp plug with metal strain relief, insertion guide and boot

    ARLI Crimp plug for installation cable to AWG23, five categories named, pack of 100

    The plug on this shelf with the longest list of cable categories, including the only mention of Cat 8.1, published for installation cable up to AWG23 — and one that never uses the words solid or stranded.

    Category rating
    No single rating is assigned to the plug itself. The first bullet names the cables it supports instead: Cat 5e, Cat 6, Cat 6a, Cat 7, Cat 7a and Cat 8.1. It is the only listing on this shelf to name Cat 8.1
    Solid or stranded compatibility
    Not published on the listing — neither word appears. What the first bullet names instead is a cable type, installation cable, which is a use rather than a conductor construction, and the page never says which construction the contacts are cut for
    Shielded or unshielded
    Shielded — stated in the second bullet, which names a screened construction with gold-plated contacts and credits both with consistent data transmission
    Accepted conductor diameter
    Up to AWG23 — stated in the first bullet as the ceiling for the installation cable it is compatible with. No lower limit is given, and no millimetre figure appears
    Accepted cable diameter
    Not published on the listing — the outside diameter never appears, although a boot and a metal strain relief both have to pass over the sheath
    Load bar presence
    Supplied — an insertion guide is included with every plug, named in the fourth and fifth bullets as part of what arrives in each polythene bag alongside the plug and the boot
    Pass-through or standard body
    Standard — the fourth bullet describes installation with a crimping tool, and nothing on the page describes conductors leaving the front of the body or being trimmed flush
    Pack quantity
    One hundred — stated in the title and in the fifth bullet, each plug bagged with its strain relief, insertion guide and boot
