Login screen increases temp?

[taz1004]

My CPU temp usually stays around 40'C if I let it idle within Windows. Even after heavy gaming and 3DMark tests, it rarely goes above 45'C. But when I leave the machine idle at Windows login screen, the temp reaches above 50'C. And then the temperature starts to drop slowly. Is this normal and anybody else experiencing this?

This is because of the chipset registers that control CPU idling. At the login screen of windows 2000,when you choose if you, your large chested missus or the nipper are gonna be profiled up, I think (I have observed this too) that the opsys does not put out the call for the northbridge to operate in a normal fashion.

A lot of motherboards also do not do CPU idling on Durons. A simple changing of a register within WPCREDIT can fix this.

The easiest solution if u r worried about the 50°C is to just to not leave it at the log-in screen

Thanks for the info but... what does all that mean in English? :)

When the computer is idle ie, not doing anything, the OS (operating System) will tell the CPU to halt, ie. rest. Because the CPU is not busy, then the temps will not be as high.

I find my temps rise at the login screen in win me. I use CPU Idle so I think my temps go up at logon screen because CPU Idle is not running and not keeping my CPU cool. My CPU runs at 27C Idle and 36C under heavy load (rarely above 34C).

What are you doing at the logon screen anyway?
set up a guest account and log in as a guest when u r not using ure PC and run Folding @ Home. much better use of idle time
