Aight lads and lasses of MacRumours

I have a question: What are some of your reccomendation for fan cooling on 3,1 (or any of the old pre trashcan macs)?

I've set this cooling profile but one of my Ram banks is a good few degrees hotter at any given time.

For context I've repasted the CPU's and the Northbridge chip, and the ram have little mini heatsinks on them which I attached with thermal pad tape (Well worth a go by the way, temps dropped a good 10 degrees over the ram banks doing that). It's running a flashed EVGA nVidea GPU too, but I can't see that screwing with airflow that much.

Is it something you guys have seen before and can it be managed or should I stop worrying about it and just be happy I was able to scoop a mac pro for £150 all in that runs catalina?

I don't think you have anything to worry about. I tried Macs Fan Control for the first time today. Setting Active preset to Full blast is a great way to move some dust. I should probably do some cleaning.

Haha fair dos. First thing I did when I got mine was open it up to clean it and hoo boy these things are dust farms. I'll probably give it a yearly clean just to keep ontop of fan dust. I'd highly reccomend getting the little 10x10mm heat sinks and attaching them to your ram if possible (I Used 3m double sided pads) as it really lowers ram temp.

On a side note, I notice your GPU shows up on fan control whereas mine doesnt. That's interesting! I wonder if it's a driver/OS issue- I'm on Catalina with DosDude1s amazing patcher and a flashed windows EVGA version of the GTX. Did you install any drivers? I was considering it but as everything is working fine on my mac I'm loath to do so incase I screw something up as I'm using this machine as my WFH/Freelance computer right now.

I didn't think I would see so much dust fly - I'll do some vacuuming before I try that again. The fans take a few seconds to ramp up to full blast and they get loud (the computer is usually silent - much more quiet than a PowerMac G5 Quad I have).

My RAM has the Apple type heat spreaders already.

My GPU is a Mac Edition card.
Anyway, it doesn't show a temperature so I don't know why it shows up in the Macs Fan Control UI.
There is a preference to add Discrete GPUs. I can deselect that to remove the GPU from the list.

I am using DosDude's patchers for Sierra, HighSierra, Mojave, and Catalina. I make custom boot HFS+ partitions (marked with a (B)) for the apfs OSs (Mojave and Catalina) so they can appear in the Startup Manager. They boot to a blessed EFI Shell that run a startup.nsh script (like the one created by DosDude's apfs patch). But I found recently that I can make the firmware load drivers before the Startup Manager even starts so it can show apfs volumes too. NTFS is also a possibility (but it's not a good idea to boot Windows in EFI mode without OpenCore to protect NVRAM).

I tried a XHCI EFI driver (USB 3.x) in rEFInd but it hangs (load manually to test before adding it to drivers folder or Driver#### NVRAM variables) - I guess it needs to be rewritten to work on old Apple EFI. I think the NVMe driver works so I could add that as well to Driver####.

To make the apfs Recovery partitions appear in Startup Manager (marked with (R)), the bless command can be used with the --folder and --file options. The Startup Manager shows the Preboot volumes (marked with a (P)). The Startup Manager shows the root file system of each apfs OS as "EFI Boot" because the bless command won't bless it (it blesses the Preboot file instead). For Catalina root (shown next to rEFInd in the above picture), the data volume has the .VolumeIcon.icns file - it needs to replace the root file system's sym link so the Startup Manager can see the icon (and also when you boot into a different OS).

Here's some commands I use to create the multi line disk labels:

Code:
# show the appearance of all the .disk_labels before updating them
dumpAllDiskLabels

# output some makemultilinedisklabel - the result can be edited like below to make the label appear as you like
makeLabelCommands

The MacPro3,1 firmware requires it32 type icons inside the .VolumeIcon.icns file. I created some custom tools to convert the format that newer macOS versions use.

Have had a Vantec fan blowing across the PCIe slots (items within) for years.
Mounted on top of the RAM cage when MP is together.

Wow, thats an impressive programming rabbithole I don't have the know how to follow you into! I was just happy to have remote flashed my GPU with mac firmware :p I think that's probably it- I'm using a flashed windows GPU whereas you're using the mac one. As I say, my mac functions perfectly and the GPU is detected and I get the precious boot screen so I'm okay with that on a 12 year old mac!

also that ram you linked to is EXPENSIVE hahah
