The Blackmagic Design Spares - ATEM Constellation 8K - Fan refers to the high-performance cooling units located within the 2RU chassis. Given the immense heat generated by 8K processing and 40 channels of 12G-SDI, the Constellation 8K utilizes a sophisticated thermal management system consisting of a primary fan bank and dedicated power supply fans.

Maintaining these fans is critical; if the central FPGA (Field Programmable Gate Array) overheats, the unit will "thermal throttle," leading to dropped frames or a total system shutdown to prevent permanent hardware damage.


Fan Configuration

The Constellation 8K typically utilizes two types of fans:

  • Main Chassis Fans: Usually a bank of 3 or 4 high-CFM (Cubic Feet per Minute) blowers located in the center or rear of the unit. These pull cool air across the Mezzanine and Main PCBs.

  • PSU Internal Fans: Each 400W Power Supply module contains its own dedicated small-form-factor fan to prevent the voltage regulators from overheating.


When to Replace a Fan

  • "Fan Failure" Warning: The front panel LCD or the ATEM Software Control displays a critical alert indicating a specific fan has stopped spinning.

  • High-Pitched Whining (Bearing Failure): If the unit sounds like a "jet engine" or emits a grinding noise, the ball bearings inside the fan have dried out or failed.

  • Intermittent Thermal Reboots: The switcher works for 20 minutes, then suddenly shuts down or glitches. This is often caused by a fan that spins up but fails to reach the required RPM under load.

  • Excessive Dust Accumulation: If a fan has been operated in a dusty environment, the blades can become heavy or the motor can burn out from the added resistance.


Technical Installation Note

Repair Level: 2 (Moderate).

  1. Safety First: Unplug both AC power cords. Even when "off," the redundant power system maintains standby voltages that can be hazardous.

  2. The Cooling Shroud: In the Constellation 8K, the fans are often housed under a plastic or metal "shroud" that directs airflow. You must carefully remove this shroud to access the fan headers on the Main PCB.

  3. Pin Polarities: These are typically 3-pin or 4-pin PWM (Pulse Width Modulation) fans. Ensure the connector is notched correctly; forcing it on backward can damage the fan controller on the motherboard.

  4. Airflow Direction: Fans have a small arrow on the plastic casing indicating the direction of airflow. Crucial: Ensure the replacement fan is blowing in the same direction as the original (typically exhausting hot air out the side or rear).


Diagnostic: Dust vs. Failure

Before ordering a replacement, try these steps:

  • Compressed Air: Power down the unit and use a can of compressed air to blow out the vents. If a fan was simply "stuck" due to a dust bunny, this might fix it.

  • The "Spin Test": With the unit open and power off, flick the fan blades with a plastic tool. If it stops immediately (rather than spinning freely), the motor is seized and needs replacement.


Pro-Tip: The "Machine Room" Effect

The Constellation 8K fans are designed to be audible because of the cooling required for 8K video. If you find the fans are constantly at 100% (max volume), check the ambient temperature of your rack. If the rack is above 30°C (86°F), the fans will never slow down. Improving your rack's overall ventilation can extend the lifespan of these fans by years.

Is your switcher reporting a specific fan number failure on the front screen, or are you just hearing an unusual noise from the chassis?

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Sleek, upscale and supremely comfortable
Size: 9, Color: Cognac
I did not know that Marc Joseph makes hands free slip ins. I own four pair of Skechers, and I thought they were the only game in town. I decided that I wanted a pair of business casual pair of wingtips. I already own two pair of Skechers Mark Nason wingtips in blue and black nubuck, so I bought a pair of their cognac colored. Perfectly fine shoes, but when they arrived, I didn't like the color, so the search was on! I found these cognac-colored Mark Joseph's and hands down, they fit the bill for what I was looking for! I actually bought two more pair of Skechers in the brown family in the same oxford, elastic lace style: One pair of another style of their Mark Nason line and one pair of their Garza line. So now I am comparing three pair of Skechers to the Marc Joseph's. Obsessive, I know :). Luckily, I have a Skechers store near me for easy returns. The look I was going for is a sleek, business casual that I could dress up or down. Three things that I love about the Marc Joseph's are the beautiful cognac finish: the white yet lower profile soles and the more formal, narrower toe style. The MJ's nailed it with the color. They have a slightly darker, more lustrous and glossier look than the others. The color alone looks classier and pairs well with black pants which I wear for work almost every day. The white soles are exactly what I was looking for. The visible rise is probably about a third of the thickness of the others and are a much more subtle, classier look. They offset the cognac color nicely but are not that in your face, sneaker looking, thick white sole. When I was comparing them to the others right out of the box, I thought they would be too narrow and tight because they looked sleeker and narrower than the others. But they fit perfectly and were very comfortable right out of the box. Upon closer inspection and comparison, I realized the narrower, sleeker look is because the eyelets for the elastic shoelaces are closer together that give the illusion that the shoe is narrower. They compensate for what might create a tighter fit across the top of your foot with two stretchy "gores" they are called on either side of the upper part. The "slits" are nicely finished, and you can't see the stretchy part and add a nice design touch to the shoe. But between them and the elastic shoelaces, they must stretch just enough to make them extremely comfortable across the top. So, if you have a high instep/arch, they should accommodate it nicely. Last but not least, they are very comfortable shoes. I wear a size 8 1/2 to 9 and my foot is slightly on the wide side. I bought the size 9's and they fit perfectly. If you are between sizes or have wider feet, you may want to size up a half size. Because the Skechers have much thicker soles, they might be slightly more cushioned, but the MJ's are cushioned more than enough for my purposes and very comfortable. Plus, they actually just feel better on my feet. I can't speak to how durable they will be as I just got them, but so far, so good. So, there you have it. I rely on other people's reviews a lot when buying online, and especially for shoes. I know it's always a crap shoot, particularly when buying shoes online, so I hope this review helps. Everybody's feet are different, but I highly recommend these.
