I'm designing a case and will be building a prototype once the unconventional frame is worked out. It will use 4 slim 120mm or 140mm fans, I will probably end up prototyping both to compare results.
So naturally, i've been looking into all kinds of fans and slim fans. I know that fan stats are not always accurate and there is no standard, nor is there accurate controlled testing on 99% of fans to verify stats.
Which ones are the best? Which ones exist? At the moment, I believe the prolimatech sleek vortex 120mm and 140mm are the best. They suit my needs by having a very low minimum and PWM (400RPM min).
Raijintek, cryorig and silverstone are a few other 15mm slim fans off the top of my head. Been using frostycpu's great page of all fan sizes and thicknesses to help out.
I might try out some 12-13mm ones but they might be a bit weak in terms of performance/noise.
