Not that this isn’t a a good fan, but the pricing on this is incredibly deceptive. The normal retail price is 25.95 so you are saving 95 cents but not the 40% the page lists. The only reason the system probably thinks it’s saving that much is because the price randomly spiked to that price on the 8th and was back to the normal price the next day.
List price = MSRP <> retail price or Amazon price.
Some fun things worth noting:
#1 these 100% sound like a vacuum cleaner or jet engine at anywhere near full 3000 RPM.
#2 two years ago these were selling for $17.63 at Woot
#3 $19.99 is the cheapest these have gone on Amazon this year (July)
They don’t really often go on sale but they’re not exactly a high demand item either.
I would personally love to own six of these for a pull/push config on an AIO for fun.
