Hi all,
I will probably be looking for a small fan for where the speaker
normally goes in my spare time. I can always use an external fan for
now. I also want to test the kpa100 with the existing fan. In any
event, I didn't want to imply that the existing Elecraft design is
deficient.
Issues would be:
1) How to hook it up? I was thinking of paralleling it with the
existing fan, so they would go on and off as needed.
2) Fan direction: I would think it best to have this fan to be in the
opposite direction of the original fan. If the original fan blows, then
this one should suck, so as to not fight each other.
3) Also omitting the speaker and adding a fan or not, will change the
ventilation paths in the EC2. It could actually create a problem with
cooling a specific area of the enclosure.
4) If I attach the 2nd fan to the first in parallel then can the supply
take the extra current?
5) Even if I don't add the 2nd fan, it may be good to install the
non-connected speaker to properly seal the enclosure to allow cooling as
originally intended.
Food for thought,
Steve, W2MY

Hi all,
I was looking at my KPA100 while waiting for some parts and am
wondering..... Since the KPA100 is in the EC2 case, I'm guessing there
is no reason to put the speaker in the EC2 by screwing it to the
heatsink of the KPA100.
What if I found a small fan and placed it where the speaker should be to
compliment the small fan at the back of the kpa100? With the opening in
the heat sink it seems a perfect substitution. Any suggestions?
