CPU temperature monitoring software for Pentium 4?

I use PC Wizard. Don't know about the compatibility with the Pentium 4. Do not see why not. Here is the link. Hope this helps. Good Luck.

Hi, you can upgrade your CPU to around 3.0Ghz any 478skt CPU will do for your PC. Go onto ebay, and search for 2.8Ghz or 3Ghz CPU, on the side panal it will ask what socket you wish to choose, tick the "socket 478" option and de-select anything else. It will show you all the listings, you should be able to get a 2.8Ghz Pentium 4 for around $15. Which is a VERY huge boost. But, it is not for todays gaming standards, if you was planning on useing it for gaming. Edit: Please will you people stop suggesting things that will cost hundreds and hundreds of dollars? He asked what his CPU could be upgraded to, I bet you people didn't even bother searching for his awesner. Straight away you turn into trolls. Core2Quads? C'mon... He probbally only wants to go on the internet or somthing.

Coretemp is what i use but i don't know if it is compatible with P4.

Realtemp should work with a P4?

Check your bios if there is CPU monitoring and turn it on if there is.
