Finished testing Noctua D14 vs Scythe Mine 2.
Both twin tower coolers, but it looks like the D14 is better by a hair even with weaker fans.
Noctua D14 with stock fans and Nt-H1 paste.
Scythe Mine 2 with Kazemaru 2 1700rpm and Ultra Kaze 3000 with Tuniq tx-2 paste.
Test setup.
Intel i7 2700k
Asus Z68 V-Pro Gen3
G.Skill Ripjaws 16gb 1600mhz
Crucial 128gb SSD
Msi Gtx 560 Ti
Antec One case with 1900rpm scythe fans for airflow
Noctua was dead silent even at full while the Scythe was a tornado in my room.
