This was a great read, I have always had a love of PC fans, and the technology behind them. It'd quite a complicated engineering challenge to produce a high static pressure, high rate of airflow, and minimize noise while maintaining high reliability. I'm one of those folks that has no problem dropping significant money on fans every time I do a PC build, and so far I have very very rarely ever had a fan fail on me, even after decades of running at high duty cycles. The thing I always marvel at is how high the draw is for some of these fans. At one point I even retrofitted a system with an external radiator for water cooling that used 120V 120mm Panaflos and was separately powered from the computer.<p>I wish folks took cooling more seriously. There are so many devices that benefit from active cooling but rarely get it, or even being strategic around placement, positioning, and mounting to make convective cooling more effective. Thermal limiting is such a common occurrence on modern electronics if you don't give due consideration to cooling, as we've moved towards more passively cooled devices, including PCs (laptop especially).
