Performance Update making MBP run warmer?

    Has anyone else noticed their MBP running slightly hotter since the recent performance upgrade?

    My MBP's CPU was previously idling at about 37C, and is suddenly idling at anything between 44-50C, seemingly for no reason (no extra processes running that I'm aware of, and no changes in general usage), and hasn't dropped below 42C in days. I realise this isn't hot, by a long shot, but it's a pretty noticeable increase from my previous idling temperatures, so I'm naturally a bit curious.

    I've cleaned out the vent with compressed air (though the MBP is very new, so I wasn't expecting much effect), and that predictably did nothing to bring the temperature back down to its former average... so I'm wondering now if there's something in the performance upgrade that makes the CPU run a little hotter than it would've done before?

    Not noticing any difference here. MBP still running in mid 40C with the 9400M and around mid 50C with the 9600M GT.

    I haven't installed the Performance Update yet! I have opted not to for the time being. I am not even sure that I have Firmware version 1.7... Just got this MBP about 3 weeks ago, would it have it preinstalled? 0.o I haven't chosen to manually install because I have heard some bad things about it-- as well as about the Performance Update. ><

    Thanks all. Apparently, I'm just being paranoid... but it's always good to know. :)
