Never said their stuff was cheap. Yes, it's expensive, but it's also the best RGB Ecosystem, imo. Keep in mind, the Commander pro is both a fan hub, fan controller, and RGB controller all in one package. The fans are the expensive part, in all honesty. You can always go with someone else, and then see if the RGB can be controlled from another piece of software, but that's pretty hit or miss.

If the device does not show up in Device Manager, it generally means there's an interoperability with one or more chipsets on the card and your board. The only way to be certain, is to try the card in another system until it works in one, which would confirm. Now, because you have an HP system, I can basically guarantee it's an interoperability because their BIOS is utter trash and has all sorts of interop issues will all sorts of chipsets (I deal with this at work all the time).

The Silencio is a case for Micro ATX, or Mini ITX. The MSI B450M PRO-VDH is a Micro ATX board so it should be fine. In terms of the GPU, CoolerMaster's site lists the "Maximum compatibility - VGA Card Length" as 355 mm /14.0 inches. The Asus ROG Strix Radeon™ RX 5700 OC, is 305 mm ( 12 inches) long, so it should fit just fine. The GPU will clear the heat sink, that's pretty much always the case with modern boards, those heat sinks just aren't tall enough under 99% of cases to pose an issue. Also of note, you can fit a tower cooler up to 155 mm (6.1 inches) tall.

Short answer, is no. There are certain "drives" (read, partitions here) and certain folders and files you should never be touching, and thus shouldn't have access to. For instance you really shouldn't be touching the recovery, or EFI partitions, and many system files you shouldn't be messing with.

Yes. I tried running a WD Black, my 850 Evo, and my CP off one SATA plug to an RM850x, and it was drawing so much current to power the lights, the fans, and both drives, that I initially had detection issues and my WD Black wouldn't even show in Windows. I've now got the CP on it's own SATA line back to the PSU. I'm not sure if it was too much on 1x 12V rail, or just for the cable itself. You should NOT be daisy-chaining CP's like that, it's a lot to power that many fans and that much RGB off a single SATA connection to the PSU.

Sounds like you need to go to a PC shop and confirm via a 2000 series.

According to this: http://www.deepcool.com/download/pdf/RF120_3IN1_EN.pdf, they are supposed to come with a controller. Otherwise, they are PWM and would be controllled for RPM that way, like all other PWM fans. The RGB is +12VGRB, and your CPU_LED header is the same:

To what version?

Does the RAM tab in Task Manager show a chunk of Hardware Reserved RAM, perhaps even 4GB of it?

Yep. I'd get the Commander Pro for simplicity. It comes with 2 channels for RGB control. 1 will power their RGB kit, the other will connect to the Lightning Node Pro that comes with the Commander Pro. It will then control the RGB for the fans. Then, the Commander Pro has fan headers which you will plug the actual fan cables into, to allow for speed control.

You can't add TB3 to that board, it has no TB3 header on it. The Gigabyte cards are intended only for use on Gigabyte boards, just like Asus' is only meant for some of their boards. There's some work arounds to try and make it work, involving getting the non-DCH version of the TB3 software from the Microsoft store, but it's not at all supported. In terms of the laptop, it's USB-C, NOT Thunderbolt 3, so a TB3 dock will not work correctly on it. If it's a newer dock with a Titan Ridge controller, it will go into what's called USB-C Failover mode, which severely impacts it's performance and capabilities, but allows it to work on a USB-C system. Alpine ridge controllers cannot do this at all, and wouldn't work at all with your Surface Laptop 3. In my opinion, your current setup is not possible.

So, their AIOs are self contained, and control off their own connections, ultimately connecting via a USB header connection to the board for full control. The RAM is controlled through iCUE communicating with it. All peripherals do the same. Only the Lighting strips, and RGB fans have to go into the LNP, or CP. The LS100 is fully self contained and connects via USB. If you skip their RGB fans or strips, you need neither the LNP or CP, as the rest of it, doesn't have RGB headers that need to go to anything else. So, for Iris, her 3 front Light Loop 120's are connected to the Lightning Node Pro, which is then connected to Lighting Channel 2 on my Commander Pro. Then Channel 1, has the 4 RGB strips (daisy-chained) connected to it.

Yeah, the Rift dislikes ASMedia greatly. The company I work for has done a bunch of testing, and generally we push people to use Renesas as they seem to be far less problem prone. I can't recommend a specific product as I don't want to violate the rules, since I have no permission to represent my company here. However, if you Google around for Renesas, and Rift, you should find solutions out there. The 3 dots came up consistently with ASMedia controllers.

You straight up, cannot. As I said, you HAVE to use their stuff. The Commander, and Lightning Node Pros are their RGB hubs/controllers and used for all of their RGB stuff fans and lights. The exception, is the AIOs are self contained. You cannot plug their RGB strips into anything other than the Lightning Node Pro, or Commander Pro.

No. You have to use their stuff. Yes, it ends up costing a bit more, and it can be a bit more cumbersome to link up, however you get considerably better control, and more consistency that way. Once you're in their ecosystem, it's best to just stick in it for all RGB components so you have a central control spot. So, for their RGB strips, you'll want either the Lightning Node Pro, or Commander Pro + their RGB strip kit.

I don't know why... but no one has questioned what the drive, partition, or files are that you are trying to mess with in the first place. So, wanna shed some light on that? You may be trying to access stuff you shouldn't be messing with, or trying to access stuff in use by the system. I think we should confirm what you're trying to touch before we try and grant blanket "solutions" which may be inaccurate depending on what you're doing/trying to do.

Just use Corsair's stuff, and it's guaranteed. Their strips are super easy to hook up to Commander Pro, or Lightning Node Pro. Their ecosystem is closed, so afaik, there's no boards out their with iCUE headers, or any 3rd party stuff compatible with iCUE.

Have you installed the latest drivers as well? Does the BIOS see the USB ports or any devices plugged into them? Have you ever used this case, and the front panel USB on it before?

If you stick with Corsair for everything else, yes. iCUE can control ALL Corsair RGB products. Lighting strips, RGB RAM, RGB fans, the i series of power supplies, their AIOS, even their ambient lighting kit (the LS100). Example:

So, the MSI B450i Gaming (Plus AC, I'm assuming as I don't see any other variant) should be pre-flashed with 3rd Gen support, and should have BIOS 7A40vA7 for Ryzen 3000 support. If you have that, 7A40vA8, 7A40vA9, 7A40vAA, or 7A40vAB installed then you should have the correct BIOS. Anything older, and you'll need to flash the new BIOS. This could be problematic if you're on an older BIOS though, as there's no flashback utility. As such, you'd need a 2000 series CPU to be able to insert it, and flash the newer BIOS. You could use AMD's upgrade program for this, or ask a local PC shop for assistance.

Short answer, don't.... Like, I guess it will depend on how much Aura Sync stuff you have. I literally only have my board, so I shut off the lights in the BIOS and left it. Everything else in my system is Corsair iCUE, so I control all that. I can get Aura Sync to pick up my board 90% of the time, but it doesn't seem to play well with iCUE so I ignore it. Seeing posts across this forums, and elsewhere, Aura Sync seems to be hella buggy, like worse than iCUE or (sometimes) NZXT Cam.

Do you have the Commander Pros/Lightning Node Pros/and AIO all on the same SATA power line coming from the PSU? What happens if you disconnect the fan headers from the Commander Pro (CP) and plug some of them into the board's header's directly? As much as I love Corsair and iCUE, it can sometimes be very, very buggy. For instance, on my account, I can't click on the dashboard or it crashes, but another account on my system can do so just fine. Not sure what's different. I've had devices disappear and reappear with a restart sometimes, other times I need to reinstall. iCUE is feature rich, which also means it's bug rich.

iCUE can really only control Corsair stuff. There's apparently some 3rd party library you can add to let it control other stuff, but I've not tried it. My Prime Z390-A only shows up in the BIOS for RGB control, as I can't run Aura Sync and iCUE at the same time, as it causes iCUE to stop responding to inputs for some reason. That being said, it's just the board light for me, so I care not. To answer the question at hand, no. Unless the RGB controller somehow can hook into the board for direct control, no. Most RGB controllers only control whatever lights are connected to the controller, and that's it. I've yet to see one that can control lights NOT connected to the controller.

Page A-3, shows as IDE detect. So, it's something to do with the drives. What's the specs of the full build, what was recently changed, etc? Will need more to be able to assist at all here.
