I swear by my Noctuas, they are fantastic fans. I've had a full set of them in my case for about 8 years now, even under heavy gaming load the fans will get more 'whooshy' but they are hardly noticeable and keep the system cool.
We also use way more than just our eyes to navigate. We have accelerometers (ear canals), pressure sensors (touch), Doppler sensors (ears) to augment how we get around. It was a fools errand to try and figure everything out just with cameras.
Engineers: "This is possible but we will need to equip every car with an expensive sensor suite"
Management: "So you're saying we can just remove the sensors and figure it out with your engineering magic, you guys are really good at that, you got my iPhone connected to ICloud so you must be reeeally good with technology."
Engineers: "..."
Management: "Also, anyone not up to this task is fired."
