10.5.6 - weird Safari and fan behaviour

Question

I've had it a few days now and I have found some strange behaviour....
⌲ Fan management seems a bit off - the fans are running a lot more often but I think this is because the core temp seems to be a lot higher a lot more often
⌲ This might be because Safari has started to act strange - it's cpu usage often takes up 100% or better usage (hence the high temps which kick off the fans) for no apparent reason - admittedly I open up 52 tabs at a time but I never had this problem with 10.5.5. Also - trying to copy text in sites is really fiddly.
⌲ A lot of the tabs I normally open in Safari stop half way. Sites with video often play with a lot of stutters. This is not my internet connection as Firefox opens all tabs quickly and the same videos play fine.
⌲ If I leave Safari alone for awhile and go back and do a refresh of all the tabs everything often goes back to normal - which is strange
I guess you'd have to say that it boils down to intermittent unstable Safari, apps hogging massive cpu usage which then kick drives the fans.
