Hmm... it must have had a high TDP like my PC with a fast fan right now. Try underclocking your MacBook Pro processor (The Intel Core Duo Yonah T2500 I believe), but beware slower performance.
Or maybe try keeping a large fan cooling your MBP but is not ideal since you're going to take it anywhere where there's no electric supply, like the beach or the taxi, right? Also you want a long term solution if you're taking it anywhere.
I heard that Snow Leopard includes power improvements according to a PCWorld article. So it's Snow Leopard's power improvements and has little to do with 64-bit, other than your processor not having SpeedStep or your software is too bloated, sucks more RAM and leads to the RAM to suck more power because it is overloaded (well not literally, I mean at the point your MBP gets slow due to the bloatware).
My evidence on the bloatware sucking RAM sucking power is that Windows 7 netbook users get an average 47-57 minutes according to Engadget. I went on the comments and said that Windows 7's hidden bloatware sucks power (well in this case bloatware sucks RAM sucking power).
And SpeedStep is a technology in most newer Intel processors that automatically underclocks the processor slightly when it is running netbook level applications and overclocks the processor slightly when you're running a lot of applications or running high performance or demanding applications.
So try underclocking your processor and see if the computer can run much better with reduced fan speeds, but again, beware slower performance.
A little upgrade to Snow Leopard should improve battery life and performance while underclocking your processor to something like 1.5-1.73 GHz should give you a way to run your MBP better with (again!) reduced fan speeds and even better battery life but the less performance disadvantage.
Also do some optional ways to better improve the laptop. Add a cheap energy efficient SSD if you can. I don't know if that should help your MBP more if you use it a lot but it consumes less power so meaning less heat. This is optional and expensive though, but it would be recommended IF your MBP gets 4x hotter than a pizza that just came out of the oven a few seconds ago cooked for 10 minutes at 500

Video chipset failing, or hd failing. Apples disc utilities suck. There is no surface scan in it. Get the hd makers bootable disc and run the full test including surface scan. I had a drive fail and never got the SMART warning, even though it was enabled.
Go back to Apple and demand they use their hardware tester disc on the machine and tell you what is failing.

^ That's way more likely than dust or overclocking. Unfortunately, I don't have any bootable Hitachi CDs. I downloaded an iso, but the Mac won't read any of my CDs. Luckily, the Windows computer is nearby, and its burner works just fine.

^ Dammit, the superdrive is too fucked to even boot from CD. Any ideas on how I can accomplish a drive fitness test without using an optical drive?
reactosguy:
First of all, it's underclocking.
And ask for a CAD$100 external SuperDrive. Your internal drive won't work but your external one should. ;)
