[Elecraft] Quiet fans for K3

[Jim Finan]

I use Noctua fans for most everything. Have used them for years and haven't had any failures. I use them for all systems I build for clients and myself. They have several varieties for each size and the ones with rubber mounts are generally the most quiet.  Also have a choice of 3 and 4 pin plugs.

While most of their fans come with rubber mounting hardware, the ones I suggest have rubber inserts surrounding the bolt/screw holes‎.

Noctua is an Austrian company but fans are built in the orient. Top quality with 'SSO2' bearings. 

Both Amazon and Newegg have them and the prices generally run from about $15-18. Just make sure the specs (CFM)  match (or are better).

While I haven't measured them on mine, they look like 80mm.

Subject: [Elecraft] Quiet fans for K3

What are the current options for quiet fans for the K3? My original fans 
are pretty quiet but at this time of the year when the windows are 
closed and the ambient noise level is nil, the fan noise really starts 
to bug me. It's the very slight rattle they make when they start winding 
up.. (In the din of summertime, can't hear myself think, let alone fan 
noise.)

Sources? Prices?

Are the newer Elecraft fans quiet? My PA is only a couple of years old 
so the fans are pretty recent model.
