Used them all tbh, tried corsair and noctua.
Though currently, I'm using asaka piranha 120mm in a pull config. Would prefer push and pull, always better temps but 250D can't allow dual sets of fans on the h100i.
Must say for me they are the best I've used. I've seen temps as low as 18 degs on my setup 4670k. Max temps of 66 degs. ( asus real bench )
