Mac Pro firmware

Sounds like a problem. I’d call applecare ASAP.

Perhaps the Mac Pro is similar to the G5 regarding racing fan observations.

Thermal recalibration of the processors, or sometimes the replacement of one or more of the processors, and even sometime the logic board, was required to solve the racing fans issue.

The trick is to run the hardware test, ideally the ASD test disc available to apple tech support folks. The standard hardware test that comes with the Mac does not usually provide the level of specificity required to identify the problem, but it’s worth a try.

I would schedule an appointment at your local Apple store so they can run the better hardware test disc.

Please keep us posted.

I would also like to know what firmware upgrade you are talking about. How old was your Mac Pro? I assume anything come from Apple would be the latest firmware, although maybe not. 🙂

Good luck and keep us posted.

PS… you might try installing and running SMCFanControl to see if that takes control of your fans. We run it on our 8-core to dial in minimum fan speeds of 1200rpm, to keep the Mac pro running cool 24/7.

I believe he means the MacPro fan-speed update that just showed up a day or two ago… man I knew my MacPro was quiet, but I hadn’t realized just how LOUD it has the potential to be until that reboot (the fans go full bore for about 2 seconds as the firmware is applied).

See, that’s what mine does too. WHen I first turn it on, the fans spin up real loud, then after a few seconds they quiet down and then the machine settles down for a really really quiet day. I sometimes can’t believe how quiet it is, but when it’s first booted the fans spin up like a jet.

All’s well that ends well
