Lion Running Hot

Lion is running much hotter then snow leopard. At Idle I am about 30 degrees F higher then before. And tends to escalate extremely fast from there. Any one else noticing similar trends? Or an idea on how to solve it?

A Mac with a fresh installation of Lion can run hot for a while until Spotlight finishes reindexing all the new content. This can take up to an hour.

i have 2010 MBA 11inch 2GB ram 64GB SSD.
even after spotlight indexing. i still think the air is very hot with LION. even now i have only Chrome, and MSN messenger running. my Fan speed is 2454rpm, CPU is 55'C. if i turn on Pages or Mail, the fan speed could have gone up to 5000rpm and CPU temps is 70'C.

i wish i could get Snow Leopard back and a refund for purchasing lion. i prefer a COLD stable Queit Macbook air
