    I have a Mac Pro 3,1, GTX 570, 32 gb of RAM, running 10.11.6.

    No matter what I do the fans stay on. When it goes to sleep, the monitors go dark, but the fans stay on, and I dont get that nice pulsatile sleeping power light.

    I have done the terminal command: pmset -g assertions and there is nothing preventing the system from sleeping. I powered down and reset the SMC/PRAM without improvements.

    Any thoughts?

    I also tried disconnecting all my USB peripherals/scansnap and it did not solve the problem.

    Please help!

    Is there some sort of diagnostic hardware utility I should run? Troubleshooting tips?

    Edit:

    Found the problem!

    I had a rogue printer queue.

    She sleeps like a baby now.

    3,1: Still going strong almost a decade old.

    Of course it's still going strong! The 3,1 is King of Mac Pros! :p

    Its pretty remarkable the value the 3,1 has provided. Still feels snappy for most daily tasks.

    Wonder if it will be worth getting high sierra on this beast, as I skipped regular sierra.

    I agree 100%. I bought my Mac Pro new in 2008 & it's still going strong with these few simple upgrades that I have done over the years.

    • A 4GB GTX680 I flashed myself for an Apple boot screen
    • 56GB 667MHz FB-diMMs (6x8GB plus 2x4GB) - weirdly installing 64GB interferes with PCIe SSD performance
    • 2 x 1TB Samsung Evo 850 in RAID-0 on Apricorn Velocity Duo PCIe card
    • HighPoint RocketU 4-Port USB 3.0 PCI-Express 2.0 x4 HBA Controller RocketU 1144C
    • 4 x 8TB Seagate HDD - one configured for Time Machine
    I haven't bothered to upgrade to Sierra & now I think that I'll just wait for High Sierra. The value for money of this system has been fantastic & I can see it still being useful for years to come. The only downside is that power consumption is doubtless higher than a more modern Mac but purchase of a similarly configured nMP (64GB RAM & 1TB internal fast storage & 32TB nearline storage) would cost well over £5000.

    Similar upgrades. You can grab a bluetooth/wifi card for $40 on eBay which I will probably get.

    Also skipped Sierra but will probably throw high sierra on it if its easy.
