H Series 80x25mm Fan

Introducing a newly re-engineered and up-graded cooling fan series, the HYW08025. We have completely redesigned the motor and fan blades for greater rpm, CFM, pressure and improved sound quality.  The goal is to give more output in the same traditional package size.

Over the years we’ve detailed other server and case cooling fans (primarily where this model is used) and a couple in particular are very high performance, but they are 32 or 38mm thick. This new model HYW is 25mm thick. If you do not have the room, or if you have been using some of the other YS models in this size, but require a performance up-grade .. this is “your fan”!

For comparison, we have taken the HYW08025 spec and placed it on top in the chart below. All compared models are 2Ball bearing systems and 12 volt.  Keeping in mind the speeds shown are not the fastest we offer by any means, but again, this is a 25mm fan turning at a very moderate RPM.

Prefix Speed  (RPM) CFM Pressure  (mm-H₂O) Watts  (V x A) dB  (A)
HYW 6200 80.0 17.2 7.20 53.5
YW 3300 48.5 3.8 3.12 37.0
EYW 3500 54.5 5.9 3.60 38.7
NYW 5500 64.1 12.5 6.0 48.0


Notice the improvement of the new HYW in CFM and Pressure. This was achieved by designing a new motor and rotor. Notice the moderate RPM increase (~12%) providing a corresponding increase in performance with a slightly less increase in dB(A).
