Unfortunately in your case, it sounds like you already have sufficient knowledge of the issues impacting your machine that alternatives to help cool the machine down to an operable temperature haven’t been suggested.
I know that the folks from the support side are making suggestions as well, so I’m not going to bother to repeat what they have likely told you. I would like to add that there have been a couple of tricks that they might not mention, that other customers have had really good success with.
One of those is to raise the machine up on a couple of props (1"x4"s) under the runners to increase air flow to the intake, and then point a fan directly at that (underneath from the right side) to direct cooler air into the machine. That has the benefit of shortening the length of the pauses that the machine has to go through. (And make sure that the air intake at the lower right side of the machine isn’t blocked.)
Another is to open the lid between long prints - that generally only works though if the ambient temperature around the machine is cooler than the operating range.
You said you had an air conditioned house…, it is very easy to direct the cooling to the room that the machine is in, just by closing a few vents in unused rooms. (I have to wear a sweater in my office in the summer now, but I don’t really have to have the upstairs air conditioned during the day, so it works out fairly well. And i live in Houston, where it is hot about 80% of the year.) Adding a smaller portable AC to the room is also an option to bring the temp down even further, and it won’t void your warranty.
If you haven’t browsed through the Beyond the Manual section yet, there are some very clever solutions for cooling the machines off - even in tropical climates. Here are a few, you can search the category yourself for others if you want them:
Other than that, there isn’t going to be much we can suggest. Good luck with whatever you decide to do.
