ur temp are ok but ur fans are moving slowly.
most of the fans has a rpm of about 5k.
please check if ur cpu fan has accumulated dust over it but i don't think so coz temp. is ok.
dunno about the voltages.
wait for others to confirm.

Ashfame that was just an screenshot of the software. BTW the speed of cpufan is quite fine. If it has dust on fan or heatsink , the temp. of processor will rise and hence cpu fan speed
Well .. u can't actually check overheating ... what u can do is use tools like ATi Tool or Prime 95 and stress out ur system ... and see how long ur system manage to run stable .. and keep the temps monitored the whole time via speedfan etc. ... If u find ur system stable for a very long period of time ... say 10 hrs. at a stretch .. then u need not worry much ....
Also ... better cooling can ensure lower temps. which translate into better stability and longer usage ..... i'd say make sure ur load temps are around 50c for the processor , and around 40c for the rest of the components ....
CPU cool is not at all going to help you if you are using windows xp. Under WIN2000 and XP you dont need CPU Cooling software because this Operating systems has this function these functions built in.
This systems executes automatically the HLT-command, whether there is CPU-cool or Cpu-idle or other softwares.
