Please compare the Super Flower Megacool 140 to the Iceberg Thermal Icegale Xtra 140 and the Noctua iPPC 140.
Noctua was supposed to send this fan, but they didn’t eventually. I guess they are pissed with the G2 review.
When a test of the Noctua IPPC 140mm 3000RPM for have a fan to compare it ? 🙂
Sent an email to Noctua and weirdly enough I didn’t get a reply. Will talk again to my contact there.
