I bought my last 1U server a few years ago. The space savings I thought I was gaining was quickly diminished by the fact that we weren't going to be able to fill a cabinet simply due to running over our power envelope. It was going to require a bigger circuit, an electrician to install it, a change in our cool billing, etc. So, these newer CPUs while being a lot more powerful also draw a lot more power as well. In the end the squeezing 1000s of CFM through a 1.75" aperture wasn't worth the headache. I'm glad to see cloud providers are still using datacenter standard 1U chassis. I assumed everyone had moved to Open Compute rack dimensions 537x44mm. The neighboring cabinet to ours has a 3x Walmart box fans. I thought that was pretty innovative. Just use big silent, slow, fans instead of these tiny, noisy airhorns.
