I did my graduate school work on thermal design using these sorts of things for Heat sink testing (not for fan testing, so slightly different, believe from the same company though) . Every time I hear you guys say you're doing pressure tests during heatsink testing I imagine you're using these sorts of devices for testing the pressure drop across heatsinks , so setting up a chamber to test the pressure drop across heatsinks would be awesome, ( I think you'll be able to additional pressure taps into an differential pressure sensor, then create an external chamber for the heatsinks to exist in, and use the the blower that bolts on the back as your flow source for steady flow) .
Would be neat to be able to couple the pressure drop for heatsinks with your flow characteristics you get from fan testing.

As for the RS-232, old standards like it are reliable also because of the voltage levels. USB is 0 to 5V, RS-232 is something like -15V to 15V. (Apparently to a total range max of 25V, so you're not hitting both 15s at once.) So it's way bigger than interference and noise, especially in factories where all sorts of stuff with high power use (and so potential for strong EM) are put together. Combine that with low baud rate and you've got a signal even with few or no modulation tricks to be very resistant to interference.

Serial ports are the best things available when you don't need high bandwidth for some reason. They've been around forever, and for good reason. They're ridiculously easy to implement. Everyone already knows what they are, how they work, etc. If it isn't broke, don't fix it. That's very much the case where reliability is king. USB is becoming more common, but I'll take serial any day over the mess that USB can be sometimes.

The Phanteks T30 is going to blow everything else away. Hands down the best fan you can get right now.
Arctic P12 and P14 is going blow everything else away in best cooling for the money.
If you can get your hands on some of the original Gentle Typhoons, you'll learn how far ahead of their time they were.

As a mine ventilation engineer that does a great deal of fan testing. This seem excessive... But Awesome
We make do with a set of orifice plates, manometer + peso tubes, ammeter and some hot wire air flow sensors.
If we're getting serious, we might make some inclined U-Tubes

RS232, reliable and easy af to implement.
Don't have to build a hole usb stack and then make drivers for said usb, just pipe commands over serial, any computer that can read serial well (so anything that's not win 10) can very simply and easily talk to it.

Serial is used because pretty much every sensor and MCU is able to communicate via serial. Makes system integration much easier. Sure, CAN and other methods are also available, but that's more expensive and kind of overkill for a lot of systems.

I've actually found some great utility to unboxing videos. They're great for repackaging items for RMA/Warranties, refunds and exchanges, and for reselling stuff on eBay, especially things like Motherboards, GPUs and keyboards.

You guys don't know how much this means to me. Been scheming for years on how to make this happen at my house. Because i am a weirdo. Thank you so much for being even weirder than me. You kick ass. All the love.

Having moved heavy machinery for breweries and server rooms (and far too many fridges) I sympathise with the struggle of getting it off the pallet good job lads! Much love from the UK!
