What a shame, if they had been 17.99 I would have bought them thinking they are just a rebrand. But that 9.99 price tag made me think about it. Just glad I didn't.
I am trying to upgrade fan quality, not trying to get side grades to the stock 900D fans :-p
eLoops it is, then.
Haven't used Yate Loons or eLoops yet, but I've used the Helix. And I utterly hated them. They weren't remotely silent when undervolted, and all three had kinda a ticking noise when undervolted. It was incredibly annoying. Enough that I just flat out replaced them with AP-15s, even though they are slightly close in performance to AP-15s (and much cheaper).
