Wasn't there an old Signetics App Note suggesting a 6 ft cooling fan for some one of their chips or other? Might have been a WOM (Write Only Memory.)

Hmmm. Haven't been down the fan rolling rabbit hole yet. What do you think @jonathan c and @Wes S ? Should we explore fans?

Now for the absolutely guaranteed to get you in trouble response:

Yes. While you listen, have your wife / significant partner stand to the side of the gear rack and cool the amp by waving a large palm leaf by it. This method runs silent, runs cheap. —> ……?

Ha, ha,ha...unfortunately this method do not work for me.
Keep her happy it is not cheap, and when she it is not happy, she is never quite .
But I can see someone's wife's will happily cool your gear, only for reason keep you home and she know what you doing .

I have tried a few fans over the years, and they were all too audible for me. Also, they are quite an eyesore just like tube risers/socket savers, of which I will not use either. Visual appeal of my amp plays a big role in my overall enjoyment.

I can't hear this one on low and it cools my Valhalla well. https://www.amazon.com/gp/product/B...search_asin_title?ie=UTF8&psc=1&tag=headfi-20

Thanks for the link, but that is the first one I tried a while back and I could easily hear it, even on the lowest setting.

Doesn't seem to be anything in the link.

Not sure why / it works for me. Search for this on amazon:

AC Infinity MULTIFAN S3, Quiet 120mm USB Fan, UL-Certified for Receiver DVR Playstation Xbox Computer Cabinet Cooling​

The evidence on tube life suggests keeping them cool is the top priority. Having them on socket savers gets more passive cooling on a MJ2 because there's more glass sticking out of the case. I'm thinking about adding a quiet fan or two to help also. Anyone tried this?

Actually, keeping tubes off front the case of gear, like using tube savers/adapters on MJ2, it's make longer life of your amp too. Excessive heat it is biggest lifespan enemy of all electronics.

It did not work on my phone, but it did pull up on my computer. Thanks for the link, however that was actually the first one I tried, and it is was very audible at all settings. I should mention I am blessed with really good hearing, and a very bad case of OCD.

Second is dust…after listening sessions with the Mjolnir II and after the tubes (in adapters) have cooled, I put a rectangular 4” high Tupperware clear box over the tubes…

I am right there with ya, on fighting dust. I always cover all my gear when I am not at home. I admit it is not very pretty to look at while covered, but the second I get home, the towels (gloves) come off.

I have other shapes for clear Tupperware that I use to cover Schiit Valhalla II, Woo WA3, Woo WA6 after post-listening cool-down. For the LTA MZ3, it is lint-free felt cut to shape…

Ok bro. I'm on the hunt now

I put one on my Darkvoice (since I'm not a member of the MJ club ). It's a 12v computer fan powered from a 9v wal-wart I grabbed from the stash bin, but even at 75% of full voltage it was too loud. Back to the stash bin for a computer fan speed controller, and with it turned down to 7v it's all but inaudible. Below 7v it won't spin up from a cold start (stalled), so even though I get decent cooling at 6v or even 5v, I leave it at 7v so I don't have to give it a push every time. Can't speak to improved tube longevity at this point, but the top chassis of the DV is now at room temp even after being on for several hours and it got pretty toasty previously. Transformer is even much cooler. So if nothing else it ought to help the internal components live longer.....as to whether that's a worthy goal with a Darkvoice is another matter entirely.

I knew there was something to this fan thing. Everyone has been holding out on me

Guess what fellas . . .I found another "HG" level tube. However, this time around I did not buy them all up.

Foil O Getter

I currently have the O Getter version, and it is a fantastic tube that can hang with the big boys no doubt. This tube best the Brimar CV455, with better clarity and space, while still being as impactful and musical. The sound sig, is like the 6201 PWTMDG and Brimar CV455 had a baby, combining the best attributes of both. I also have one of the Foil O Getters on the way, and can't wait to hear that one, as I think it might be the earlier version.

Nope. Not gonna do it. I refuse to keep playing your dastardly game.
