Interesting fan design VIDEO

post #1 of 18
Thread Starter 


Found this, thought I'd share it, since I've heard people complain about lack of (visual) proof concerning this fan design.

How does the Air Penetrator stack up outside of this smoke test? I've been looking for some new case fans.

It is not meant to be a case fan, although you can use it as one.

It's meant to be a straight - high pressure fan for radiators.

actually, it's meant to be an intake case fan. just off the top of my head, FT02, RV02, TJ08-E, TJ11 all use AP181 as intake fans. generally speaking, the air penetrators are louder then the typical fan of similar CFM rating due to its design, however the benefit is what you saw in the video.

the application for the AP fans are fairly specific. it's actually not ideal as a push fan on a rad tho it can function as one since it does have higher static pressure then a fan of similar CFM rating. However, as mentioned earlier it has higher decibel rating as well. there are fans with similar static rating as the AP fans but a lower decibel rating on the market which would work better as a push fan for a rad.

That is odd. Why would you want a fan that directs air in a straight line, taking in air in a case ? I bet you won't notice the difference in overall temp in your PC with a none-focused fan (same CFM).

The only use I can see is for rads. But nyea what do I know.

To create a wind tunnel in larger cases, just because they move the same volume of air does not mean the air will keep its velocity. Thus the air will travel at a higher speed for longer since it is focused.

Then again, having a good flow going through your case is possible because you can combine exhaust and intake fans to make it "flow". I don't see average cases use a straight line technique between the intake and exhaust fans so basically it needs to "bend" while flowing anyway... pointing the fan towards a GPU is one thing, then this fan could be very good, but just blowing air into a case? I don't think it will matter that much in temps.

Intakes placed a distance from components benefit from fans that have focused air pressure, especially if that air needs to move through hdd bays etc. The longer throw/penetration gives the air less time to sit around the case heating up before arriving at components, and makes exhaust fans' job easier. imo, from my experience.

Heatsinks/rads are not the only thing that benefit from good focus and static pressure, two qualities that imo are underrated for case intakes (except for bottom intake in some setups). I believe it's erroneous advice when people say such-and-such fan is only for rads. Not as important doesn't mean not important. No you don't need to slap a couple AP-15's on the front panel, but that doesn't mean you should ignore fans that produce tight current. imo.
