CPU temp higher after latest Snow Leopard updates?

[Mac32]

Hi,
I have a MBP 2.66c2d from 2009 and a ultimate MBA from 2010. After I downloaded the latest updates for Snow Leopard that was released 1-2 weeks ago, the temps have become noticeably higher.
I have undervolted my MBA, and now the CPU idles around 50-55C when browsing and using Spotfiy. It used to be 38-45C. Same with my MBP. It is also warmer by some degrees.
I noticed people saying that OSX Lion made their Mac CPUs warmer. Have Apple done something to heat up the latest Snow Leopard version I wonder?

Anyone noticed the same?

Thanks.

Probably the discrete GPU.

Did you try gfxCardStatus?

My Early-2011 17" MBP here runs very cool (SL 10.6.8 v1.1 Combo Update).
