Just tried it (my MB gets a little hot underneath), will post back results in a few hours after some testing,

Update: Seems the same did the PSU reset and no change in temperature of casing and Core Duo temp reads the same(around 62 degrees)....Saying this my MacBook isn't particulary hot it just get a bit toasty near the magsafe connector....this is probably normal.
