I’ve been running the Blackmagic Design ATEM 1 M/E Production Studio 4K for about 18 months now. It’s been a great unit; however, it has always been a little noisy. And lately, one (or maybe more) of the fans inside appears to have developed a failing bearing and the noise has been far too loud for any production environment.
There is so little info that I could find online about what’s under the hood of the Blackmagic Design ATEM 1 M/E Production Studio 4K. So, I had to pop it open to see what I was working with here. Since I was outside my warranty period, I wasn’t concerned with those consequences. If your fans fail within your warranty, feel free to go ahead and have Blackmagic to fix it.
Inside, there are three exhaust fans along the left side (one is already removed in the above image) and four fans atop heatsinks to cool internal components. The right side is open for the exhaust fans to pull the cool air from.
The three exhaust fans are 40mm x 20mm, while the heatsink fans are 40mm x 10mm (so, half-height on the heatsink fans).
I used Noctua fans in both locations. Specifically:
- 3x Noctua NF-A4x20 PWM for exhaust fan replacement
- 4x Noctua NF-A4x10 FLX for heatsink fan replacement
Because the connectors were different on the Production Studio 4K’s mainboard than what the fans shipped with, I had to cut and resolder the connections.
The wiring schematic for the exhaust fan uses a 4-pin connection and is mapped as follows:
- blue > blue
- yellow > green
- red > yellow
- black > black
The wiring for the 3-pin fans are 1:1 with black, red, and yellow.
After all the fans were in place, it was time to put the cover back on and power the unit up.
Not only did we get the one noisy fan fixed, but the device runs so much quieter than when it was new.
Noctua fans are known throughout the IT industry as a quieter replacement option inside of switches, routers, and servers – most notably the noisy 1U devices. With a little bit of time and a soldering gun, they also managed to turn the notoriously noisy Blackmagic ATEM 1 M/E Production Studio 4K into a near-silent machine.
