The "rust" is actually threadlocker. No idea why they aren't using the red or blue, perhaps it's just some generic stuff. When you're re-pasting a bare CPU/GPU die spread the past out over the whole die so that full coverage is guaranteed. You used enough excess that I doubt there's any voids but it's a good idea to keep that in mind for the future. Personally I'd use one of those cryosheets or PTM7950 since getting in and out of that thing to re-paste would be a pain and pop-out is a common occurrence in bare die applications and repasting a NAS is a PITA.

Chinese level of thread locker, gotta save a penny instead of paying for red or blue dye.

Didn't show it on video but all other screws have blue thread locker applied from factory.

Disclaimer: Normally I would be against performing such operation on a brand new device. Wait at least few months and use the product as intended, so that you look out for any manufacturer defects and also in this case you could have monitored the performance for 2-3 months to get a baseline. The reason is if day one you perform such disassembly you won't know if you screwed up or if it is the manufacturer at fault. (I understand you are a KZreadr and appreciate your dedication, disclaimer are for people watching the video). I really like the fact you have a full disassembly of a low-cost product fully documented, it is a good spot for people to get reference at some point when they need to perform maintenance or if someone is intrigued on the internals of the device. 1) The rusty compound you found is most probably a cheap thread-locker from the manufacturer, normally it is blue on electronics and sometime red on device prone to higher vibrations. You could get yourself some Blue Loctite Thread-locker and apply it, as these screws sometimes might come off due to the vibration caused by the HDD and make electrical shorts. 2) Noctua Fan is a cool touch :) A little bit over-kill but I like the choice! I can already see that in the future you'll probably build your own NAS and re-purpose this as a backup to your main NAS. Maybe we will see a mini home-lab build! 3) Plan on a secondary NAS as mentioned above, which you can set up as a backup, periodically turn on to sync with the main NAS, the secondary should be at a different spot/room or even another location, maybe a trusty family member in exchange you can offer them a small allocation.

Thanks for taking the time to write! All your points are completely valid. On the rusty looking screws. All the other screws had blue thread locker applied from the factory, which is why I was surprised to see those rust-colored screws. It could be a cheap thread locker compound like you and a few others have mentioned. You've read my mind. I do plan on building a homelab in the distant future. However, this one is more than sufficient for my needs at the moment, so it might take some time before I feel the need to go all out and upgrade! Cheers!

Thank you very much! I have successfully replaced the old thermal paste and the temps are ~5° lower than before, even with the stock fan. Seems to be an issue out of the box with some of the units.

Glad the video helped!

Are you using your M.2 as a Cache? Also, in the future you can schedule your parity to operate during specific windows (like while you’re asleep.

I did consider using the M.2 drives as a cache. However, I ended up using my Octane M.2 as storage for my appdata and system folders, which is a little overkill. There is a scheduling section for the parity and mover in Unraid. There are lots of options, for example, time of day, day of week, month, etc.

Oh the four screws to cpu fan , you needed to screw down the same nbr of turns as the other 3 screws assuming equal pressure is applied to cpu also not too much pressure that would squeeze out paste almost entirely ??? U need to monitor cpu Temps to verify reapply paste was successfully

Very good and informative video Ugreen your hot rod 😂😂😂😂

Wear and tear.

Okay, so I am going to summarize what I see. For my own benefit. You're placing the stock fan on the new NAS for no particular reason. Your drives are operating within thermal specifications. You're replacing the thermal compound on the CPU for the new NAS for no particular reason. The CPU is currently sufficiently covered by a thermal compound chosen and applied by the manufacturer. You're running Unraid, which gives you the throughput of a single disk, even though you have a four disk NAS that would provide theoretical aggregated throughput of three disks if configured in a RAID 5 array, like that supported in the manufacturer's operating system for the NAS. Ah. Good. Now I understand fully.

Even if drives and CPU are operating within thermal specs, the cooler a device runs, the better it is for the long-term reliability. So no, he's not replacing it for no reason, he's replacing it to get A) better thermals and B) lower noise both at the same time, and probably higher performance since MX-6 is most likely a better paste than what Ugreen used by default ...

@@Leseratte I believe Backblaze in one or more of their disk reports drew the conclusion that temperature had little or nothing to do with drive failure rate. I forgot to add in my original comment, that the OP immediately voided the warranty on his new device. I stand by everything I wrote and will add the following - I am sure controversial -- discussion point: Almost half of the Noctua fans people use are unnecessary, and almost half of the Noctua fans people use don't move enough air to be useful. They are quiet because they run slower and just don't move air as well as OEM fans.

As long as its within spec it will make no difference to long-term reliability, you are making up stuff you have no evidence for. Better thermals are irrelevant its a NAS performance isn't going to change or even be noticed if it does. The fan probably will give a better noise profile but he took no before or after measurements. NAS is probably going to sit unused in a cupboard anyway.

did he even test the temps before the repaste? I have the exact same unit and currently running plex transcoding at 75% cpu load and it is sitting at 65c on the hottest core, the chip is a 15W chip, if you want cooler temps just replace the whole damn cooler, thermal paste will only get you so far, and I can assure you at 15W thermal paste will never be the bottleneck of your cooling when the cooler is some thin extruded aluminum with no heatpipes
