Ok I've spent the last 3 days reading watching etc on what is the best 140mm Noctua fan for my Kraken x61 Radiator and im still sitting here trying to decide between these 2 models and it's driving me nuts i just want to place my order. So I have a NZXT Kraken X61 i want to replace the 2 stock 140mm fans with Noctua 140mm fans as I've heard NOTHING but great things about using them on a radiator. The two models I'm stuck on are the Tan and Brown Noctua NF-A14 PWM 140mm fans and the Noctua Industrial 2000rpm NF-A14 Black and Brown 140mm fans, everything i watch on both of these is stellar everyone loves them nothing bad to say at all.

Im having trouble deciding because on the specs of my Kraken x61 it says the stock fans are up to 2000RPM but the Brown and Tan Noctua NF-A14 says its top speed is only 1500RPM, will i run into any issue's if i choose them to replace my stock fans? will it not be as cool temp wise since its only 1500RPM? And the only thing about the Industrial NF-A14 is some people say it's really loud and others say it's really silent, I'm just lost and could really use some guidance or advice, i know i want Noctua 140mm fans for sure just cant choose one out of these two models.
