I just got two new drives for my server, tried adding them to the storage spaces pool and the one drive added successfully. The second drive had something go wrong. It now shows up in disk management only after a restart, disconnecting and reconnecting will cause it to not show up until restart. It lists itself as Unknown, cannot initialize. Trying to manually initialize results in the error "Virtual disk manager: A device which does not exist was specified." The drive worked normally before trying to add it to the pool. Is there any way to get the drive back so I can actually use it?

I use Primocache because using tiering through storage spaces or powershell would have meant wiping the disk and I don't have anywhere to backup all that data to. Strange things happen on the two systems I use Primocache on but I'm not sure if Primocache is the cause. On my desktop it will randomly crash the OS and clear out the cache, on my server it will randomly disconnect the drive being cached.

This happens seemingly at random. Earlier in 2020 it crashed 6 times in one month, then went several months without any issues. The last two blue screens happened in October and November about a month apart and then it went quiet. I think one of the game servers is causing it but I'm not too sure. I think in November we switched it to a stand alone and it might have solved the problem. Unfortunately this game server is not one that I can just throw into virtualbox like I'm doing now as it needs an actual GPU to run and I haven't found a way to pass through in virtualbox. I'll keep an eye on it but the crashes seem to be caused by graphics drivers. I don't know if the game I mentioned above is causing the problem. It is known to be a buggy game. Rebuild time is not really a concern, I was more concerned about if read times are affected. Write speeds could be offset with the cache SSD. My largest transfers are typically only 5GB or less. Are you saying I use rsync to copy the files from the first drive to the second drive? This was kind of my plan, try to isolate problem software into its own VM so that only one VM goes down instead of the whole machine. It's not really something I can do with the way the system is set up now.

I've got a home server that acts as a storage server, between 5 and 7 game servers, PiHole (VM), Plex server, phone backup and folding server. It works pretty well for most of what it does but a couple of things are starting to creep in as problems. 1. Since the OS is windows and everything else runs inside that if windows crashes (has been known to happen even with the ECC) everything goes down including PiHole which can bring down my internet if the server does not recover. I have an old laptop I am trying to figure out how to act as a backup but that is a different project. 2. I have been getting errors with Plex transcoding for certain content. The only thing I can think of is that the Quadro p400 is having problems because it doesn't have Quadro drivers. The system uses Geforce drivers for the 1060s I use for folding which disable the quadro drivers. My plan was to convert the whole system to run Proxmox and deploy VMs as necessary but I have concerns. Proxmox can act as a nas if I understand correctly, does anyone have any experience with this or would it be better to run Truenas in a VM? Both use ZFS I think which brings me to my next problem. The drives that I use the NAS I'm pretty sure are SMR drives which I didn't think about when I bought them (they were very cheap). ZFS doesn't like SMR for things like rebuilding an array, but are there any other problems outside of this issue? If Proxmox can be used as a NAS, can it utilize cache drives for write operations? As of right now, the server runs Syncthing to copy photos off of everyone's phone to a drive and then once a week it copies the files to the NAS drives for "archiving." Is there any way to do this in Proxmox or maybe something similar? This is something I have planned for a ways off since I don't have any income right now and some additional parts would be required. I'm mostly just trying to wrap my head around some of the technical details of it.

I still use a 1650 xeon which is Sandy Bridge with a 5700xt, and while I can tell that the CPU is holding the GPU back a little in some games it hasn't been enough for me to say I need a new system. If you are wanting a 1440p 60 experience then I don't think your CPU will hold it back too much (even more so if it's overclocked but you didn't say). I only got a 75 hz monitor for me because I knew I wouldn't be pushing high frame rates with my CPU, and I'm more of a maximum quality gamer. I don't see the point in buying a 144hz monitor if I need to turn down settings. You could always just get a GPU and monitor now and try it out and if it's not living up to what you want you can upgrade the rest.

So I looked it up and apparently I'm tripping. It was never available for Navi, supposedly the driver switches automatically.

I have a 5700xt and could have swore I saw it just a month ago.

So am I crazy or did AMD remove the toggle for compute performance from the control panel? I know it was there at one point and though "oh, that'll be great for folding" but can't find it anymore. It's not where they are saying it's supposed to be, dose anyone know where it is now or did it get axed?

Using a mix of target and my normal curve did work, though it wasn't quite what I was thinking, it's good enough. Until it was brought it up I hadn't looked into the target function all that much. Once I started messing with it I figured out how it works.

The NF-A12x25 would be my choice, the NF-F12 and NF-P12 are also considerations though might not be as good.

Seeing how much these were hyped up, I bought some for my system to see how they are and, I'm not super impressed. I've tested 3 P14s and one P12 and they work for what I was trying to do, but I feel like these are being hyped up a little too much. They are very quiet (most of the time, see below) and they move a good amount of air, but their build quality is lacking. The blades are very porous which is probably why it is so cheap and light. I know it's porous because one of the blades came in contact with the case while testing and ripped itself off. One of the other P14s came in contact with its own frame while I was slowly turning it over to see where the noise mentioned below started. this put a chip in the blade but it is still working normally. All of the p14s I tested make a very loud moaning nose when mounted as a top intake... unless it is pulling air through some sort of obstruction. The noise got worse when mounted to the case. It's almost like the fan is trying to lift itself out of the housing but it's strange that it doesn't do it while a as a top exhaust. Putting a dust filter in front fixed this more or less. No this is not the same noise reported at 1000 RPM as starts around 500-600 RPM and continues to max speed. On one of the fans I noticed the fan blades were not an even length while spinning This didn't seem to add any vibration or noise, just something I noticed. I didn't check the other fans. The fans have extremely close tolerance to the frames of the fans, I have an ongoing problem with one of the fans actually sucking in its dust filter so it starts rubbing on the center hub. I had this with other fans as well but usually pushing the slack out of the dust filter and tightening down the screws to hold it fixed this issue, the P14 is still rubbing on it though. I managed to mostly get rid of it by putting some foam padding between the fan and dust filter to space them out more. Based on what I experienced, they are not bad fans but they they are not the be-all-end-all of fans. They have their place in the market but shouldn't be recommended as a substitute for something like Noctua or Be Quiet fans. Their use case should also be considered before recommending them. They shouldn't be right up against dust filters (at least ones that don't have rigid frames to support them), and they probably shouldn't be up against the frame of the case on the intake side because of the shattered blade. The picture below is post amputated fan blade, I don't have one of the inside of the blade since I couldn't get my camera to focus. Normally I try to glue fan blades back on, but what ever kind of plastic they used it doesn't seem to work well with super glue.

Try a Pure Rock or Pure Rock slim. You can also try a 212 black. I don't know what the prices are like in Greece. You won't get as much out of these coolers as you would probably like though.

This annoys me... Not like this would have been a champ, but I figured I could use it for some extra points.

The Q300l is not well ventilated at the bottom of the case for the GPU. If you have a GPU I would recommend turning your power supply upside down or removing some of the remaining PCIe brackets so air can get in/out around the GPU. This case will benefit most from having a negative pressure setup so I would take the stock case fan and run it at full speed (provided it's not too loud for you) by plugging it into your fan up without any control. This fan most likely can't be controlled in this current setup is unless you are willing to do some electrical engineering work. I would take your two airflow fans and mount them on the front of the case for intake but you would fair better with static pressure fans instead. You can take the 140mm and mount it on the top of your case as an exhaust at the back. Tie these three fans together with the fan splitter cable on your open fan header. Ideally you should have two high static pressure fans on the front as intake tied to the fan header on your board with at least one PWM exhaust fan tied to the speed of your CPU (shares the CPU fan header) at the back and top rear of the case.

Does your fan hub have a cable to connect it to the motherboard for control? What case do you have?

Be Quiet Dark Rock 4. Should keep you cool and still support an overclock in the future.

Try a Corsair ML120? They have RGB and work with PWM for a CPU cooler, they can get very loud though when at full speed.

And here I am quietly puttering along with two 1060s...

Probably any tower cooler in the $25 to $35 range would be good enough. Some suggestions: Gammaxx 400 SE-224-XT A13 Pure Rock Slim

Is their speed set too low in the BIOS?

Help me, I can't stop tinkering with the software... I have a couple of things I've been wanting to bring up: 1. Can we have a feature that would allow fans to ramp up fast but take a while to come back down. I'm having problems with my CPU fans not being able to keep up under loads where the CPU temp is up and down a lot (handbrake batch transcoding). The CPU gets hot fast so I need fast response times but then the fans don't remove the residual heat from the cooler. I feel like this might be unique to me since I'm apparently at the limit of this cooler. 2. Would this software work with an external fan controller like the Corsair Commander? This is more of a curiosity. 3. I have a motherboard with fan headers that can kind of be controlled, but they follow presets from the BIOS and just run at a fixed speed. I have a piece of software from the windows 7 days that lets me adjust it on the desktop but not automatically. Would a log allow you to see if this is something that can be controlled as well?

Putting in a deflector plate won't work since you are just making a high pressure zone on one side and a low pressure zone on the other. The air will just flow around the edges at a higher velocity to make up the pressure difference. You are better off making the top front fan an intake to build a high pressure zone at that part of the case which will allow air to be displaced towards the rest of the components.

They put it down there so they could put in that GPU support bracket that is doing a great job of holding up those PCIe cables. Woops, didn't realize this was a necro until I saw the other thread...

What kind of light strip are you planning on using? Is it RGB? What motherboard do you have, and what kind of RGB is compatible with it. Are you just planning on using standard non-RGB LED strips? Do you want your case fans to light up. Do you plan on using a liquid cooler, if so are you planning on keeping the fans that came with it? What do you want out of your fans, silence, airflow, static pressure? What kind of noise do you prefer, low or high frequency?

I think the choice to have a fan pulling air through the fins is more interesting than them cutting down the PCB to put a fan there in the first place. Most fans can't maintain as high pressure differential while pulling air through something as they can pushing air through something. The fan design on the 3080 and 3090 are very different though so maybe nvidia found a design that can mitigate this. If I had to guess as to why they did this, I would say that it is a noise thing. They can run the fans faster for a lower noise level because the fan blades are causing less buffeting because the air they are pulling from is less dense to begin with. The fins could also help generate more laminar flow into the fan which should reduce the nose further.
