Did anyone bother to verify the rating of this fan vs. the factory one? Does it have the rated capacity the original has? It is rated to operate at "low" speed without heating up or some other malady? Is the construction such that the lifetime is more than a few months? Is the current draw similar to the original? Assuming the voltage is such that it will not catch fire if it gets into high speed mode of course.
My fan is fine with me but maybe I should be happy that my hearing is 10db down from 0-1500 and then after 1700 I am virtually deaf at 50db down. Makes a fairly good wife filter. 73, Jim KG0KP -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Harry Yingst via Elecraft Sent: Tuesday, August 19, 2014 11:19 AM To: Dr John H Farmer; elecraft@mailman.qth.net Subject: Re: [Elecraft] [K3] Fan Replacement Thank you That is the same I found I hear the air move but not the fans For me it really improved my listening pleasure ________________________________ From: Dr John H Farmer <zen...@netspace.net.au> To: "elecraft@mailman.qth.net" <elecraft@mailman.qth.net> Sent: Tuesday, August 19, 2014 7:02 AM Subject: Re: [Elecraft] [K3] Fan Replacement Hello Group, I just want to share my experience in case it's of interest to others. I have excellent hearing and I have K3 #5102 and while it's a rig with outstanding capabilities, the fan noise has always bothered me. My K3 has the Utec fans and even on low speed, there's something about the quality of the fan noise that's bothersome, quite apart from the volume, which I find distracting even through over-ear headphones. Early on, I wondered if I had faulty fans from a bad batch. I replaced them with a new pair from Elecraft, but they were as noisy as the originals. Well, today the problem is fixed. Inspired by Harry's posts on the topic, I swapped over the Utecs for a pair of Noctua NF-A6x25s. It took 20 minutes. The difference took me by surprise. They are very, very quiet even in a silent room and I can't hear them through the headphones at all. The quality of the sound is softer somehow - just like moving air and without mechanical overtones! I worked CW for an hour tonight to get the rig warm and these fans have transformed the experience. I'm very pleased. Thanks Harry. 73, John VK7JB ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to hlyin...@yahoo.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to jimmil...@stl-online.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
