Alphacool released their new SL-15 fans today
www.alphacool.com
They price at € 11.69 (US$ 14,17).
Compared to the Noctua NF A12x15 (chromax) they definitely are cheaper (in Quality, too I suppose) and in terms of specs also a bit worse.
If you will run your fans failry low anyways tho, I suppose it won't make much of a difference to Noctua.
If you care about color and were to buy the Noctua Chromax NFA12-15 then you would save 10€ per unit. If you e.g. go for a 2 rad Ncase M1 style setup and you need 4 or more then you definitely save a a bit of money (although at that price point: would you cheap out?)
I'm tempted to buy and try it when I will build my Acat X2 dual rad buildin Q1 2021. Competition is always nice.
What are your thoughts?
