Hi Will1384,

Your guide works like a charm thank you. It is pretty straight forward than some other methods I had tried before.
The temperatures for CPU were pretty high, hence the fan noise. To fix that, I also used NullCPUPowerManagement.kext as well. But that stuffed up deep sleep so I had to use the sleepenabler.kext too. They seemed to complement each other just fine. At some stage I chucked in the Voodoopowermini.kext but that spoiled the harmony a bit so I gave that a miss.
Just a heads up for everyone.. If you do a memory upgrade make sure it's 100% compatible, I learned the hard way. Took me 2 weeks and numerous reboots due to various KP which stopped after reverting back to original RAM yesterday?!. A working RAM doesn't mean compatible! I found the original 1GB is just fine for everyday use anyways. Thanks again...
