Drop voltage or increase fan speed

I'm running a fairly old laptop with a p4 3.0Ghz CPU. The fan on it runs at all or nothing, which is a pain in the backside because "all" is bloody loud.

I'm looking to either run the fan at 50% or drop the voltage on the CPU to drop the temperatures (thus stopping the fan kicking in at all).

However, speedfan won't pick up the fan and RightMark CPU can't detect/change the VID, so I can't do either at the moment!

Any ideas here or am I stuck with a loud laptop?

Cheers :)
 
You're going to have to get the fan going really, I can't see how you could drop the vcore and if you did you'd have to drop the clock speed a lot, it'd still be an oven-class Pentium IV at the end of the day.

Tried maybe clearing out the fan, re-applying thermal paste to CPU? What about the latest firmware on the laptop?

The fan should have an in-between setting, it's possible that your laptop is just getting far too hot?
 
It's a Northwood P4, hitting max temps of 64. The fan kicks in at 60 degrees, which is why I wanted to drop the vcore ever so slightly to drop the temps to stop it hitting that 60 mark.

This laptop uses PhoenixBIOS, however I don't have access to alter the things I want (says I need to contact the supervisor/admin). I've cleared out the heat sink which was absolutely disgusting after 4 years of use! Reapplied the paste too which has improved the temperatures a lot, so the fan is on a lot less, however it still hits the 60 mark under load.
 
not really much else you can do mate a laptop bios isn't as configuarable as a desktop one, they just run really hot under load a cooler pad might help but still gonna get fan noise.
 
Going to look at updating the firmware as apparently you have more access/ability to fiddle with the newer versions :)
