Mentor Graphics have just launched a community for anyone interested in electronics cooling at http://communities.mentor.com/mgcx/community/mechanical_analysis/electronics_cooling
Feel free to use the community to network with peers, exchange tips, pose questions, share industry news, offer opinions, and read blogs, etc. Mentor Graphics customers can also share models and macros under the Models sub-community, which is visible to those who've logged in with a SupportNet login. Otherwise registration just takes a few seconds.
