Got bored looking thru fan listings and specs and made my only excel worksheet of the fans I've looked at and have.
The bold ones are the ones I have. Also have a grading system.
Feel free to add. I didn't give public access, cuz just in case of trolls or people deleting it.

I have one sickleflow in the back, Seems to do a better job sitting vertical. Makes less noise. I don't normally care about noise, but I don't like wearing my equipment out too early. Have a bunch of Corsair SP 120's that will go on a radiator, I'll try and add my thoughts to this thread when that gets rolling.
