Wasn't this a song from The Animals? "The Housing of the Cooling Fan"?

Isn't it
Cool is probably a term that everyone interprets differently.
You see a rack (attached to the post slightly ahead) containing a setup.
When I touch the steel plate of the rack - in listening mode- it is cool, but when I touch WAU on the cover, it is nice and warm.
When I touch the mono amplifiers (bass) with fans underneath, they are as cool as the steel plate of the rack. The same is true for the Wiim devices.
No more, no less.

My point is simply that even without an added fan, it will continue to work. For you. For me. For everybody. The WiiM devices are designed well and function well-within the thermal parameters set by the manufacturers of the internal components.
Sure, the amp might feel warm to the touch to you. You are not a class-D amplifier IC. Your hand is also not a class-D amplifier IC. Would you worry if your sauté pan got hot to the touch? If the amp is built to component spec, then trust the amp and the chip manufacturers to know what they’re doing.
Just saying.

And I thought I was the OCD one. Cooling fans. Power cords. Damping factor. I cannot believe the arcane hills people choose to die on around here. Me, I connect all my sh… uh, stuff, plug it in, turn it on. If it works like it should and sounds good, I’m happy. If it all sounds better than the gear it replaced, I’m ecstatic. And if I get lucky and it blows me away, then I’m blown away. I followed this complicated process twice with WiiM - first with an Amp Pro, and again with the Amp Ultra - with all the success I wanted for both times. Three times, actually - the last was upgrading my sub to an SVS. Each step was the upgrade (or more) than I had hoped for, each one made me a happier listener, and all on a retiree's budget. My WiiM devices paired with some decent speakers now have me looking forward to those opportunities to kick back and crank up some tunes and hear everything that went into producing them. What more could you ask for.
As others have said before, it's almost cool with no fan.
The point is that you are talking like you found out some dirty secret about the WiiM Amp Ultra and because of the ingenious move of adding a fan you have been able to mitigate the design error:
There is no design error in the WiiM Amp Ultra. It works and will continue to do so for years to come with no additional fan.
No such thing as a noiseless fan. If you cannot hear it, it really does work for you. Keeps me wondering why you have to shout at us when your fans are all silent.
I haven't seen anything in your posts on this topic indicating that you understood the real problem with the TPA3255 chips. It's not the case temperature. It's the problem of the high energy density because of the very small contact patch these tiny chips have to offer. The key to keeping a TPA3255 based design healthy and happy is to quickly dissipate the heat away from the chip. That's exactly what the heat pipe solution employed by WiiM does. Heat does not simply rise. That's pub-physics, at best. Heat transfer occurs in the direction of decreasing temperature, driven by the local temperature gradient. In other words: Wherever there are cooler temperatures, the heat flux vector will point into that direction, no matter if its upwards, downwards or sideways.
It is and that individual feel is totally irrelevant for if the chip gets toasted or not. It doesn't care for individual perception.
It's totally up to you if you are happy or not with the case temperature of any device. If you don't like it the way it is, you are free to either ditch it or help yourself with cooling fans. That's all fine, you can do whatever you want and additional air flow will never be a disadvantage. Nobody can force you to accept a surface temperature that makes you feel uncomfortable.
But please, don't try to tell anybody that there is a technical problem just because you prefer a different design. Objectively there is no technical problem. No more, no less.

I don't know if this is truly amp ultra specific, but when I fill the queue with a qobuz album and an album located on my nas, the Wiim simply hangs after playing the last track of the Qobuz stream. It never starts playing the music from my nas. Not even when I tap a different track from that nas album in the queue.
I didn’t know that wiim supported tracks from different source in the play queue. If anything from what you’ve said, I would have expected that last added content would have overwritten the queue and played just played the NAS, rather than Qobuz content.
I guess it doesn't support it.
If i want to play an album from the nas, i have to clear the queue (containing qobuz and nas tracks) and add them as a new queue.
Not i have to try that on my Eversolo and Bluesound too, to see if they do it the same way or not.

Something else I noticed this morning:
After playing from Qobuz, and having the Amp Ultra go to standby when going to bed, the next morning, it doens't want to resume the Qobuz playlist, doesn't react to presets on the remote (for TuneIn radio stations) nor does it want to start playing music from my nas.
A reboot fixed it all, but this shouldn't happen.
btw, going into the Qobuz app and trying to use the Wiim from there also didn't work. It couldn't find the Wiim, even though it was connected to my network (-50dB) and I could browse my nas music folders from within the Wiim app (though it didn't play).

Next time this happens, before you reboot submit a ticket to WiiM via the more/feedback section in the app so they can inspect your logs. As this is primarily a user forum, simply tagging admin won’t give them the necessary diagnostic information

"Reboot or powercycle your devices and/or router" is in my dictionary strongly linked too WiiM. 
Never had this with any device other than Windows PCs. Did not had it with Cambridge or Bluesound. Ok when it happens sometimes, but in my feeling it is much too often here.
But for me more the uncontrollable reboots or restarts of my Ultra were one of the reasons to ditch it. Eventually a bit too much "features"?

Hm, I have 4 WiiM devices in daily use, and only had to reboot one of them once. Probably some features are more problematic than others - or perhaps integration with some streaming services is more buggy?"Reboot or powercycle your devices and/or router" is in my dictionary strongly linked too WiiM.

For my opinion it was too much, at least for me and that is the only person I can write for. When reading the answers for many issues it seems to be felt as normal. I am from the camp: I do not care why something I bought runs, it has to run.
And please do not misunderstand my post in the Draconian thread. Same as I said about the LMS community is valid for you, @harkpabst, @Wiimer and others. I applaud your work in helping people. But I am done with problems I never knew I had them. Happy Christmas, mate!

Actually, I'm a 100% with you on this. These are all consumer-grade devices and user's shouldn't need to be engineers themselves to make them work.
To be fair, IMHO WiiM do a very good job for the most part, but there are issues as well. WiiM devices seems to be very intuitive on some aspects, and then surprisingly convoluted in others. I find it great that members of the community draw attention to such issues, and that WiiM are often responsive to such reports. But I also understand how some may find all that very tedious and don't want to bother with it at all.
Thanks for the kind words, and merry Christmas to you as well!
BTW there was no misunderstanding on my end, IMHO your post in the other thread is perfectly reasonable.
I don't think that anybody would disagree.

If you feel like the device behaves in a way it should not, send feedback through the WiiM Home App every single time. Don't think, "by now their software should work error free, they had so much time to work on it". The number of possible combinations of hardware and software components and their versions is close to infinity. WiiM really made it as easy as it gets to use this feature. Even if you're not sure if there really is a bug, send feedback anyway, let WiiM work for you.
OTOH, just because you encounter something unusual doesn't necessarily mean that there is any issue with the WiiM device. Don't be surprised if others tell you they never came across your problem despite daily heavy use. Both can be true at the same time.
If your main focus is to get a problem fixed real quickly, the a hard reboot is often very effective. Don't misread any recommendation to power cycle the device as stating that daily reboots would be required or normal. This is totally not the point.
"I never had any issues with brand X but countless troubles with WiiM" might be a gut feeling. But you won't be able to prove such a statement. I have quite a number of not so tech-savvy WiiM users amongst friends and family (some because of my recommendation, some not). In the vast majority of cases the devices simply work the way people use them. I certainly don't remind them of pulling the plug once in a while.
