Prolimatech reportedly has a new fan on the way that is based on the PT12025 fan developed by Prolimatech and Air Propulsion Labratory if photos uncovered by EXPreview hold true. The new PT14015 is a thin 140mm fan that is designed to balance airflow and noise as well as to be compatible with many tower-style heatsinks without blocking the memory slots.
The Prolimatech PT14015 is 15mm thick and has 17 14cm-long blades. Interestingly, it has mounting holes that line up with 120mm fans that should increase the compatibility with existing radiators and processor heatsinks. The curved fins have a sharp leading edge, and the 17 moving blades and increased 140mm form factor should make the PT14015 a fairly quiet fan.
There is no word yet on pricing or availability, but EXPreview has several photos of the new fan. As far as fans go, it looks pretty cool (pun intended).
