Hello,

I've been using Poser Pro 2010 and other software on my New MacBook Pro for several months.  It has always been silent.  I just loaded Poser Pro 2012 and whenever I use it, my MAC makes a noise as if a hard drive or fan is running.  The sound does not go away unless I turn the MAC off.  I've never had this with any other software.  I'm not even doing much - just loading figures.  Any others experienced this?  Any idea what is going on?

Poser uses the whole cpu if it can, so it's probably your cpu fan ramping up.

Poser is quite light on CPU's exept when rendering.
For a render it runs at a full 100%CPU.

So after the render is done the CPU (and fan) should cool and slow down.

There must be some free apps around to check your systems activity and temperatures.

After opening a scene or bringing new content in, Poser 9/Pro 2012 will run a background thread that's creating the texture cache with mip maps in it (actually, several threads). Earlier versions of Poser didn't do any texture cache creation until you started a render, which caused some extra delay before the render started. That might be why your computer is running its fans when it wouldn't with earlier verions of Poser.

If you don't like the new behavior, you can turn it off on the preferences under Render/Texture Caching/Run in Background Thread.

Correct when loading items, the cache loads the textures.
But this should stop sooner or later.

The CPU goes full bore during a render, but all should slow/cool down after a render is finished.

The OP states the fans keep on running till he turns the MAC OFF.

That is why I sugested a system temperatures check to see what is happening, and when.

He can check with texture caching turned OFF in General preferences.

Sounds like your GPU kicked off because of the 2012's OpenGL viewport and your macbook switched from the intel graphics over to your 3D card, so it needs more cooling. It's normal, however you may want to have adequate cooling and ventilation on your laptop, like a laptop fan.

these MBPs may have faulty fans, may become unbalanced due to grime on the blades. if no native util to check CPU/GPU temp and fan speed, try smcFanControl or iStat.  MBP may be very hot on one side.  maybe hotter when using battery.

When I travel I use a MBP 6.2 2.66 GHz 2 cores. In the apartment the company puts me in while in China there is a white painted small shelf I work off of. I know exactly where to place my MBP (the brown outline) so it is exactly in the same place as last time due to long IDL high setting renders I run at night!

Otherwise I don't have a high fan noise issue. The setting stewer mentions I have set at 500 MB and I have all preview shadows off in the preview rendering settings.

Waiting for the newest refresh of MBP's from Apple and waiting even longer for the MacPro desktop upgrade for my monster at home if they ever occur vs going the hackintosh route.
