That is FANTASTIC news re. the new card on its way. No doubt this is going to make things rock and roll. Heck even on my MBP it flies with the latest cards. Not sure how your budget is, but if one really wants to see FCPX FLY - and one has the option - fast drives make a huge difference. I have the Thunderbolts and omigod I was SHOCKED what a difference it made to overall performance.
Re the fan issue I'm not at all an expert on this field (who really is an expert on any field computer related lol), but I can say that before I present to you the equivelent remedy that sounds like "trash your prefs", I should point out that the very nature of FCPX virtually taking over your machine guarantees a lot of fan engagement - no matter what the machine. Mine is runnning pretty much constantly as well - but keep in mind my projects are very very complex compared to your average user. More complexity - more computing - more heat - more fan.
It could also be that after you get the new card, this will power down more often as the machine wont be choked as often.
Having said all that, I have had fan issues in the past that were always solved by firmware updates, zapping PRAM and/or SMC. From what I know SMC is most connected with fan issues on MP's. Here are those options...
Fans
The computer’s fans speed up quickly and remain at high speed.
The computer’s fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
To reset the SMC on a Mac Pro:
1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2. Unplug all cables from the computer, including the power cord and any display cables.
3. Wait at least fifteen seconds.
4. Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5. Press the power button to start up your computer.
Another way to reset the SMC on a Mac Pro computer is:
1. From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2. Open and remove the metallic outer door.
3. Press the SMC_RST switch that is located slightly below and to the right of the row of diagnostic LEDs. Use a non-metallic, non-conductive object, such as a wooden pencil. Note: Mac Pro (Early 2008) does not have an SMC_RST switch, refer to the reset procedure steps in the previous section.
4. Replace the metallic outer door.
5. Press the power button to start up your computer.
As for PRAM
- Shut down your machine. All the way down, not sleep or logging out.
- Press the power button and then press command-option-p-r. You have to make sure you get those keys pressed before the gray screen comes up or it won’t work.
- Hold those keys down until your Mac reboots again and you here the startup chime.
- Let go of the keys and let your Mac reboot normally.
When you log back in, you’ll probably will have to adjust your mouse speed, time and date/timezone, and a few other things, but otherwise you should be good to go.
Maybe start with the SMC because of the fact it is the controller of the fan usage.
But again - maybe you dont need to do any of this after getting your new card AND keep in mind, it is kind of normal for the fan to run a lot when working on FCPX with heavy timelines etc. I have 4 machines always whirling away 😉
Other than that, surely someone else has the magic trick buddy 🙂
