Curious: anyone else use 120mm Brushless fans in their ATX homelab builds? (lemmy.korfmann.xyz)

Been running San Ace 120x38mm 0.8A fans for a few weeks now and have been super happy (they're not silent but that's fine since they're sitting in the furnace/HVAC closet in the basement). Just wondering if buying them 2nd hand was a smart move or not. The particular ones I got are rated for 70,000 hours of use and they were in good shape, but I've been wondering if anyone has had any die on them before, and if so after how long?

I'm a big fan of 120mm for the airflow to noise ratio. They tend to last. You figure they're doing less revolutions over their life than a high rpm smaller fan.

I used to overclock back in the day when that was still a thing (2004-ish) and 120mm fans were amazing with a speed controller, have them slow when using computer normally, and speed 'em up when playing a game.

oh overclocking is still a thing, I do that on my desktop, fan curves can be handled in the bios/uefi. I like good quality higher rpm fans for even desktop use because even at lower speeds they still push a ton of air and are a lot quieter than the cheaper fans on the market. still not absolutely silent, but they don't bother me. That's what headphones are for haha

oh definitley. I usually use 140mm when possible, but they’re harder to find on the cheap in the brushless offerings on eBay. My switches (all 1U) are a different story noise wise, but it is what it is.
