I have several fans left over from old PC builds. Most are Noctua, NZXT, and a several Corsair. I also have more than enough extensions and splits.
but I'm not sure how many fans I can chain to...
I am looking for silent cooling fans to add either to my display or sump. I'm running a rimless tank so my criteria is sleek and quiet. Nothing bulky. I also run a Profilux 4 so I have checked out the GHL fans but they are pricey. Let me know what you are running on your tanks.
