I ordered a lot of S9's (January Batch) and all of them came with the Y.L. D12BM-12D Fan (yellow colored sticker). But one of them came with a Nidec Ultraflo fan. Putting my hand in front of the fans, it is clear that the Nidec is not as powerful as the Y.L.

Should I be concerned? Anybody else have that fan? It just seems weird to me that machines from the same January Batch have different fans.

I have seen the same thing on my miners. Interestingly, I have one miner that always runs much cooler than the rest and that one has the Nidec Ultraflo fan on it. I have actually tried to find more of those fans as I am considering replacing the fans on the other miners but so far I have not been able to find a source for those fans.

My farm has at least 3 different brands of exhaust fans, all from one batch of miners... nothing to worry about.

I was just going to mention that I get 2-3 different fan types with my large orders of s9s. Its normal and if they put the fan on there, its good enough to get the job done.

My S9 that I did a review about also had Nidec fans, no issues. https://bitcointalksearch.org/topic/reviewguide-antminer-s9-135-ths-1320-w-bitcoin-sha-256-asic-miner-2676763
