[Amps] Henry 4-K ultra blower failure

[edmund weber]

 Greetings to the list,
    The exact replacement for this blower is no longer offered by Henry Radio. They
 are recommending a Dayton 6FHX3 from Grainger as a near match, however this
 blower gives less than half the cfm, (140) at twice the rpm, (3000). Am I wrong in
 thinking this would give the tube less cooling and more noise? Thanks for any advice
 on this.
