Case Fans: GP-14 vs AF140 Quiet

[Tech Wizard]

Hello team,

 

I'm rocking a Define R5 (which came with 2x GP-14s), and I have installed both as front intake, and bought an AF140 LED Quiet for rear exhaust. The GP-14s in the front is making some weird buzzing sounds, which is starting to get slightly annoying. Noticed Corsair's AF140s Quiet edition are 35 % off in Norway, and was thinking of buying 2x and swapping them with the GP-14s. Are they any better than the GP-14s at all, or same? RPM and dBA is slightly higher on the AF140s, and the GP-14s have slightly better CFM, so spesifications-wise the GP-14s wins in all scenarios, but I'm thinking of what the 13 blades in the AF140s can do. What do you guys make out of this? Here's a picture of setup:

Edit: They are going for $15 each.

I'd pick up two Noctua NF-F14s for the front since you can't see them and there's restricted airflow at the front.
