I believe the U14S optionally supports a second 140mm fan as well. I'm currently running the SP3 version with a second fan. The Noctua website describes the NH-U14S-SP3 as having the following feature:The NH-U12S DX-4189 . . . two 120mm NF-A12x25 fans. . . For such machines, two fans may actually be an advantage since if one fails, the other will continue to operate.
That quote about the second fan does not appear on the Noctua page for the DX-4189 version of the U14S. But I suspect you can still add a second fan because the difference is the mechanism to mount the heatsink to the CPU, not the mechanism to attach cooling fans to the heatsink fins.Anti-vibration pads and fan-clips for second NF-A15 (optional)
For users who want to achieve even better performance by adding a second, optional NF-A15 fan to create a push/pull setup, the NH-U14S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode.*
