They provide decent case air and while i bought em when they first came out several years ago, they have been running close to 24/7 and are still totally good and totally silent. I suspect the twister bearingh thing is a mod to make them so they can lie flat.

A clarification please. When you say "don't lay them flat", do you mean not running them horizontally or not having them stored horizontally? Because right now i have them stored in a box with another dozen fans and they are kept horizontally... They go bad just by staying in their box horizontally?

I don't know what the new "twister patent" does exactly, but the Twister pressure, are heatsink fans, They go up to 1800 rpm. High static pressure, so i don't expect them to have high CFM. Maybe the twister thing served to increase rpm?

The Lepas, are case fans and i suspect are rebranded Enermax enlobals.

dont run them horizontallly for long periods of time. even a moth is maybe ok, but these are looooong life fans. Mine are actually on their third case and motherboard.

what it sounds like is they build a rifle bearing into their enlobal system. This would solve the horizontal thing quite handily. enlogabls can do static pressure moderately well. Static pressure has more to do with blade design than bearing though.

Thanks. Fortunately i have no fan running horizontally, so that won't be a problem. Wow, 3 cases same fan. Long life in deed. Good to know they live up to the hype. biggrin.gif


Yes, the more the fan blades are flat and parallel compared to their "chassis" (the fan frame), the more pressure they make. The more they get vertical, curved on their inside, the more air they move, but less pressure. There are actually some figures out there.

3.845 mmH2O (the official claim)

2.23 according to coolingtechnique
