I don't think Noiseblocker makes 140mm E-loops but I agree they got other great 140mm offerings. I was between the Cougar, the Akasa Viper and the Phanteks XP fans but the promo discount on these was too good to resist. Everyone I spoke to who owned these fans was very happy with them. I will be sure to let people know what I feel about them.
Meanwhile, does anyone have experience with the EK DCP 4.0 pump? I wanted to know if it is enough for a CPU/motherboard/480mm rad loop. Thanks!
