[Elecraft] K3 KPA3 Fan Upgrade Question

[list1]

Hi Brian,
I'm sure others will chime in.  What mode are you using?  What power?  What
SWR?  What's the room temperature?

At 100 Watts, for MARS I need to lecture on USB for 20 minutes at a time.
No problem what so ever.  With digital modes I do need to cut the power down
to 50 Watts.  I never hear the fans go on.  I think you need to give us all
the details.  I would never dream of replacing the fans on the K3.  Perhaps
the temps need to be recalibrated.  I just would hate for you to go though
all that work if it wasn't truly necessary.  It is such a well engineered
radio.  I'm sure Elecraft has the temperature management aspects covered.

Hello,

I am currently in the process of upgrading the fans for the KPA3 100 Watt
Amplifier module because the heatsink temperature gets too high for my
liking.
