How to tell if SMC firmware is installed properly...

Hi
I live a bit far from my Apple Store so I thought I'd ask on the forum before I did the whole Genius Bar - back- and - forth trip.

I recently had my logic board replaced along with a rattling fan.

After which i found my MBP (2.16 core duo from last july) to run much quieter and cooler. I noticed that my fans came on more often and heard them come on.

Everything seemed fine. Then I had my bottom casing replaced (because of a scratch I found after having my logic board replaced -- which i wasn't too happy about but AppleCare helped me out).

After picking up my MBP again. It seems like the fans dont come on as often anymore and the temperatures are as high as it was before i got my logic board replaced--but i don't hear a noise.

Would anyone know if there is a way to check if the SMC firmware update is properly installed? I am wondering why the fans dont come on as often . I've been using SMC fan control lately which helps but I would rather my MBP control its own temperature without me having to adjust the fan speeds. It woudl be most helpful when running programs in Windows XP bootcamp mode.

Any advice would be great thanks.

Love O.
