An interesting post Tony. I have exactly the same issues with the right side panel heating up with a typical front panel temperature reaching 43C. This has only happened since installation of the second receiver which virtually cuts off the airflow inside. The front panel typically runs hotter than the PA.
I have already gone down the road of cutting six vertical slots in the right hand side panel to assist with air flow. Regrettably it makes no difference to the temperature. The only way to lower the temperature significantly is to have the fans on permanently. This way there is some air sucked through the vents in the panel and I can drop the temp down to the low 30's. Given that the high temperature of the side panel does not appear to have any detrimental effect I have now given up worrying about it. 73 Barry VK2BJ -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of K2ZLS Sent: 14 May 2009 21:06 To: ELECRAFT@mailman.qth.net Subject: [Elecraft] K3 COOLING VENTS Hi, There have been enough posts here about the temperature inside the K3 to start me thinking. Mine also gets very WARM on the right side by U12 and U13. You all know how "boxed in" the Front side of the K3 has become and now we are looking at additional features being added to the inside of the box. The way the cooling fan is now, there is little or no circulation of air in the front side of the K3. Another poster wanted to add bigger fans but, you know, that will not solve the heat problem because the air can't get to where it needs to go. I would like to "CROSS VENTILATE" the front area by adding cooling vents, similar to the configuration of the speaker vents, to both side panels. There does not seem to be any worry about RF leakage at the rear vents where the AMP is and the side vents can be fashioned the same way. I know that Wayne feels that the cooling is adequate but, I think this would be a worthy modification at this point, if only to let the HOT AIR ...OUT. If someone knows how to punch out this configuration, I would gladly supply the panels and pay any costs involved. 73's and Thanks.
