RAID isn't a backup. RAID protects you against a single drive failure is all. If multiple drives go down simultaneously or the controller itself malfunctions then you lose everything.
Is this too much voodoo?

once i get what I can, I'm going to get it backed up ASAP.
I'm planning to buy 2 5tb Drives next month for backups going forward.
It doesn't seem like the complexity of RAID is worth it anymore. Just get a quality drive (use BackBlaze drive reliability blogs as a starting point, at least to give an idea of which models to avoid) and run regular maintenance on it. DiskFresh can usually complete overnight, so schedule it to run in the evening. I like a two drive system. At home I use Macrium Reflect to take daily images to drive D: and I make sure DiskFresh runs on both C: and D: once a month or so.

Well ideally what I want to do is use my spare celeron system to create a Raid 0+1 setup with 4 2tb drives as a file server with 2x 5tb ESATA bakcup drives, its been my goal for awhile. I just need to source a copy of Server 2008 R2 or newer, because I want a domain as well so I can enable roaming profiles.
I recommend RAID 10, not RAID 0+1.

I've got what wasn't recoverable at least

Recovered our wedding photos and video 🤣 (she really only cared about this for some reason)
Great! Glad you got your stuff back. 😀 The wedding stuff is a pretty big deal.

yea i said, i got some games, os's and drivers recovered, she said meh
I said i recovered some of the movies, she said meh
I said I recovered our wedding photo's and videos without any data loss, she said guess who gets something special tonight
I dunno why she isn't excited I recovered Windows 1.0, 1.01, and 1.03 i mean really thats big 🤣
I've used GetDataBack from Runtime Software to recover some lost files from a failed hard drive a couple times.

It's good to hear that you got a lot of files off of it.
If there is still more that you're hoping to recover, and you get another drive large enough to hold it, then try cloning the whole disk using 'ddrescue'. It's generally available in linux distros, though I think it's usually an optional package and not something that gets installed by default. It might not be on bootable linux DVDs either, but once the live linux environment finishes booting, you can just "install" ddrescue into the ramdisk environment that the OS is running in.
As always with a low level disk utility like this, make sure you read some articles carefully about how to use it. It can be dangerous if misused.
It works similarly to the more common cloning utility 'dd', except ddrescue is designed for cases where the source drive is unreliable. In it's recommended usage, it can keep a log of which sectors it has and hasn't successfully copied so that it can resume/retry it's progress on a later boot. It also has some intelligence about using progressively smaller transfers when it runs into a trouble spot on the disk, in an effort to recover as much as possible. I think it might have options to limit the speed so as to avoid heating up the drive, but I don't remember for sure.
Needless to say, keep the source drive nice and cool as you have been doing, and avoid powering it up unless you're actually ready to run the clone operation.
Once you have a cloned image on a stable drive, even if it's not fully intact, you'll be in a more comfortable position to try other recovery methods like 'testdisk' and 'photorec' and whatever else is out there.
I recommend having not just a server with a raid to frequently backup to, but also backup your data to Blu-Ray data disk, DVD data discs, and spare hard drives stored away.

Good job getting it back - did you really use LN2 to keep the drive cool enough to recover data?
I've gone for a RAID10 system at home (almost working) going to get round to backing up to an external drive, and tape too..

yes I did, I hit it with LN2 and then immeditly put it into an eSATA Dock on my work computer. I did this 3 times 🤣

I can't justify Bluray backup, just darned expensive.
What I'm going to be doing is an external eSATA or USB 3.0 backup drive, ill buy the cage and drive seperately so I don't pay an arm and a leg for it
USB3 drive docks are a pretty good choice - you can swap HDs in an out and use anything available - so very flexible. External drives are more limiting I find. I use a dock in combo with a second internal HD that is used just for backup - fastest solution for everyday backing up.
All my ComputerLab stuff is stored on a networked mirror array, two 4 TB USB 3 drives. I just use software Raid (Windows 10 Storage spaces), I never got the rage about hardware RAID / NAS. I back the array onto a 4 TB external Seagate drive every now and then and put it out in the storage room.
My main desktop, I use a SSD but have FileHistory enabled, also comes with Windows 10, which saved onto a platter drive.

yes but a cage offeres better protection than a bare drive.
Honestly what I'd love to have is one of those drive cloneing stations like we have where i work.
I'd just clone my backups 🤣
