I know you all missed it, but I just wrapped up an epic Happy Dance on my way back from the mailbox!
Can someone suggest suitable thermistors for 1.4 amp bias per channel. I'm not sure I can run that high in my chassis but would like to be ready in case it can take the heat.
Thanks,
Marty
EDIT: re reading the article I see that NP already gave the answer.

Fortunately all it takes is a gentle breeze to have a very nice improvement in temps.
I still don't know how they got all those parts in that bag. Now, get to work!
This is Nelson’s recommendation.

There are a boatload of inexpensive 3 and 4 pin fan controllers out there. In a relatively well controlled home environment, maybe just using the power pins at a reduced voltage (coinciding with an acceptable noise level) and an inexpensive pcb thermostat is the way to go. Co
st wise it's pretty much a draw.
I'm reasonably sure it would cost more to diy a control but I'm 100% behind any such effort. Not everything is measured in $$

you're given with relatively small amp, small case, and all you're doing in last dozen of pages is arguing how to make it even smaller
then putting inside fan and controller and PSU for that fan
it doesn't got smaller that way
if WAF is so important, either grow a pair or buy integrated streamer/dac/can amp, fed with WiFi (not even PSU needed) and be done

You can’t go wrong with Noctua fans. very smooth, quiet, great bearings and high quality. I bought these little ac to dc modules on Amazon for less than $9 a pair With the intention of using them in my F5tv3 monoblocs to power Noctua fans. The 1000va Antek transformer I’m upgrading to has separate 12vac secondary and you can adjust dc voltage on these modules down to 5v. So it’s not a temperature controlled solution but you can set fan speed to what you want and when amp turns on it turns on, amp turns off it turns off. Simple solution
Ya, these guys have gotten soft.. They may be forced to build an old SOZ as punishment..."Operation of a single channel at twenty watts will require about 500 watts worth of power supply and heat sinking....", or at least a Burning Amp BA-1 at full song.. To reclaim their Pass Labs forum member cards.. 😊it seems we need new subsub forum - MiniMini Pass Labs
No, some need a 'helper' running 2 amps in 1 5U case.
Or, using a heatsink designed for a fan from Boyd (which you can't get anymore) because I got it free.
I will make my own temp sensor w/fan PWM controller. It's not about the money, it's all about the making.
Call me crazy and soft, and I never got a forum member card, so nothing to lose here....what if the credenza is made entirely of copper and you build the amp into the whole thing? Integrated credenza with ultimate power dissapation authority.
