Supermicro CSE-PTJBOD-CB3 ATX PWR On/Off Control Board for JBOD Storage
although, usually unless they stock this it would come from SM so it may be 'out' for dropshippers if SM is out, but maybe Acme or others stocking have it?
I tried calling to verify stock status since their website has no limit but nobody answered.Supermicro CSE-PTJBOD-CB3 ATX PWR On/Off Control Board... | Acmemicro

Shipping is $28 for 1 and $42 for 2
Yeah it's a bummer.
I tried the Supermicro Store but was told they don't sell it and to call their resellers.
I mean I suppose I could just throw a cheap motherboard with IPMI into the machine and have it start up with a FreeDOS USB drive.
I was just hoping to have a little bit simpler solution with the power board route.
Yeah I'm in the USA. I've given up after calling half a dozen places that list them as being "In Stock" when they aren't.
I'm just going to throw this motherboard combo into the chassis along with a FreeDOS USB drive (so it boots) and call it good. All in I'll be at $130 w/ a heatsink and IO Shield so that'll just have to do.
I don't get why the CB3 is so hard to find here and so expensive.
You might be interested in this then. If he is correct no cpu needed.
Ah, in my particular case (837 with 28 slots) there's no space for anything bigger than -CB3 there...
There just has to be an easier solution...
I can probably ignore the noise, but this amount of cooling is excessive and consumes extra watts. Helium drives run cooler too.

31 to 39C (39 ones being in the rear I guess). I'll still load the chassis with more drives this week. Maybe not too excessive but I never thought HDDs are as sensitive to temperatures as SSDs. I used to run 10~18TB drives with almost no airflow at all in my desk case. And they still go after couple of years.
As it is with everything if you run it outside of optimal values probability of failures increase.
I personally would not worry about disks running at higher temperatures. If your drives are 3yo plus or more and no SMART errors they will most likely live to 7 / 9 and then mass dieoff is risk. Which is the most dangerous thing that can happen to large array. Massive array + old disks = problems.
At least that is what Google study says:

Google research: Cranking up the heat may not harm your disk drives
Temperatures exceeding 100 degrees Fahrenheit may not be damaging to disk drives, according to new research by Google engineers which casts doubt on previous findings linking heat to elevated failure rates.

If you look at backblaze data you are running into high risk territory.
My Seagate NVR typically last like 5-7 years some specimen i still use but they backed up every day.
As i said even 45 deg C should be OK but you are increasing probabilities which will become certainties sooner or later.
How much power you will gain?

I'm looking at building a big array as well, also mixed disks. It's all data that is replicated elsewhere, and also backed up elsewhere, so it's not like mixing random disks of various sized and odd configurations is going to make my arrays very scary. But I am very curious to see what happens.
The usual advice is all around vibration, temperature and load types, but there is surprisingly little data on what actually happens of you just build a 'bad' array.
One of the things I might do is create a ±44 disk array of old disks (i.e. Samsung disks of various single digit TB sizes) for a while to see if I can get them to fail since they are old consumer drives. I'd be mirroring the entire dataset anyway and speeds aren't all that important either, but considering the reports from Backblaze and Google vs. the anecdotes from failures within days of consumer drives in 'enterprise' arrays, I'm curious to see if they do indeed vibrate each other to death, cook to well-done and lose bits as if they were a dripping faucet.

Disks are mechanically pretty simple if the thing vibrates it increases the chances of damaging the surface of the platter by head arm. (bad sectors)
also slowly degrades bearings, loosens tolerances in general.
Would be interesting to know how these antivibration technologies that WD and Seagate came up work.
