Well..almost.
Just received and installed a Silenx IXTREMA Pro Series fan in the TR4.
Pictures are on the DrakeRadio Forum at Yahoo.
This fan is speced at an incredible 14dBA at 32CFM..this compared to
25-30 dBA or more for most $5 fans.
This one is EXTREMELY quiet. I cannot hear it running from the front of
the rig. Need to get very close to it to hear it at all. It is WAY
quieter than even the 24V fans running on 12V.
They come in variable speed with thermister sensing included or fixed
speed. I tried both. they are $13 and $11 from TigerDirect.com. The
80mm units match the final cage holes perfectly and the rubber "Pin"
mounts work with no screws or other holes needed.
I would not bother with the variable speed units except on solid state
rigs like the TR7 or PS7. In the tube rigs, the temp is high enough
that they run nearly fast all the time anyway. Of course I install them
pulling air out of the cage and the result is that placing your hand on
top of the case after an hour of running and it feels cold.
I can't recommend these enough--if you are tired of the roar from fans
in the shack--these are the answer.
FWIW
