Der Mac Pro (Anfang 2009) kam im März 2009 auf den Markt. Er führte erstmals die Nehalem Architektur von Intel in die professionelle Apple Desktop Reihe ein, und verfügt über ein leicht neu konzipiertes Inneres, das auch bei den 2010 und 2012 CPU Updates beibehalten wurde.

PS Fan in RED, system idle. Sensors & Temps all OK. Ideas?

Dear Hive Brain...help!....

  1. I have a MacPro 5,1 upgraded in 2020 with better graphics card, RAM and SSD. Been working fine since then and rarely switched off. Powered down in recent heatwave and not used for a week. Re powered up to noisy-fan-time. Thanks to previous answers here, am using TG-Pro. Screenshot attached.

  1. Apple Diagnostics is no longer on my disc. I've downloaded the relevant dmg to a USB but am struggling to change the boot drive at start-up by pressing "D" etc, as this is absent post graphic card change....any ideas???
  2. So...do I just replace the power supply and see if this fixes it??? Or the fan?? (both??). Interesting rebooted from the original HDD and the problem still exists, hence unlikely a software issue?? It's possible the PSU fan is just very dirty and difficult to access to clean, thus will likely strip down first.
    • your ideas will be much appreciated. I love this machine and want to keep it going as long as possible. Thanks!

@gentlegian73384 take a look at this video at around 13:00 min replacement part number is 607-3434 Since you already know how to remove the power supply etc, take a look on here. It appears that the fan comes out the same way as it did on the older models. More info about the fans on here

This Macpro Mid2010 might be useful to you.

Well it appears the power supply’s fan has failed. These fans have a tachometer built-in which tends to fail in this way rev’ing up near the top.

I would locate the fans plug and see if reseating it fixes things as the first action. I would take the time to clean the fans of there dust buildup.

As far as the onboard diagnostics, that’s held within is BIOS chip so you should be able to get to it. You do need a USB keyboard, a Bluetooth keyboard won’t work.

Let us know what you discover, if you see something that’s not right post some pics.

Hi Dan, apologies it's taken so long to get back to you, Life got in the way.. ThankYou for your rapid reply that was most encouraging to receive. So far: Re-seating the fan's plug didn't have any effect. I removed (permanently) the optical drive and removed to clean the power supply unit. I've bought a replacement but as mine is still working have kept it in-situ. I've also acquired a scrapped/replacement fan "however" I'm unsure (1) how to actually get the fan out (can't find it on YouTube, would you believe!) and also (2) unsure what to replace the silicone/rubber lugs with that seem to hold it in place. I assume these are sound absorbing. I still haven't managed to access Diagnostic (keyboard is USB, though mouse I rarely use is blue tooth as I use a wacom graphics tablet & pen on USB for all "mouse activities"). Any help/ideas you can give would be much appreciated. Kind Regards, John

@gentlegian73384 - The PS fan is part of the PS unit. It was never offered as a replacement FRU. So you would need to either replace the entire power supply unit or which is a bit risky open the unit to ID the fan unit to see if you can locate it. Apple used a few suppliers depending on your given systems age.

Hi Dan, I think you might be mistaken here. I can physically remove the PSU totally separate from the PSU-fan which sits in between that and the optical drive bays. The PSU is quite simple to remove, though it appears I'll have to do a big strip down, even to removing the motherboard to get the PSU fan out, as the cable is tracked behind the motherboard. There's a YouTube chap replacing the fans with brown "Noctua" fans, though it sounds almost as if he works for the Austrian company that produces them. It's interesting that his video "misses out" the actual "how to remove the fan/replace the fan" section even though this is the subject of his video. It's clearly harder than it looks. He references the Apple Technician's Handbook frequently, which I've downloaded but this only shows the removal of the PSU, leaving the fan in situ. It's quite possible I may have to slice the existing plastic lugs with a knife to get the fan out but replacing with be very tricky. Cheers, John

@gentlegian73384 - which year is your system? The newer has independent fan unit and the 2012 I think did as well. I’ve only worked on the 2009 series Cheese grater (besides my own 2013 Trash Can) which has the integrated fan give this teardown a view Mac Pro Early 2009 Teardown
