If $33 is not cheap then maybe not. But I buy my delta fans at mouser or digikey, and they have a wider range of specs than typical consumer websites. They come without connectors though so there's some crimping/soldering required.

For our little rendering cluster I bought a bunch of 12.000 rpm fans to cool the rack mounted threadrippers. Worked fine, no watercooling in the rack needed and 4ghz on all cores under load.

For some reason I got all opinionated about fans and settled on delta as my preferred brand. I think because delta actually had data sheets. The cool thing is that digikey has the exact fans I want, the downside is that the fans digikey sells have no plugs.

I tried once to terminate it myself but I was too cheap to buy the correct tools, so that did not go well. and am now a bit bummed about the whole thing, I found a vendor I can trust to sell me real delta fans.. and they have no plugs. sigh will probably stick with nocturna as a good second best.
