How to reduce from 5º to 8ºC CPU Temp on your MSI K7N2 Delta!

Question

I've installed this tweak last week and it is working very stable since then. It decreased my Idle CPU Temp from 42º to 36º and Overload from 54º to 48º:

It seems that the link to the tweak is broken, I've found another one:

This is what the article say:
Just tried it for the first time..It works GREAT
My idle temps are now 26c, down from 34c. That's 8C. I can have Winamp, IE and messenger running and CPU temps don't get by 29c.  Once i fire up, SETI though...I get back my regular Load temps at 39c.
Some of you probably know about it, already....here's for thousand others that don't.
This tweak can drop your idle CPU temps down as much as 8c, maybe more...depending on your system.
First thing you need to do is download WPCRSET & WPCREDIT.
They're both in this zip.
- Extract to a directory.
- Run "INSTDD.EXE". Click Install. When done, you will be prompted for restart. Hit Yes! -
- Then go back to the folder with extracted files, and open "WPCREDIT.EXE"
- A ms-dos like window will pop-up. Move the blinking block (with arrow keys or your mouse pointer) until it says Offset 6F at the buttom. Now, click on the two digit number where it says "HEX", and change it to 1F (The Hex for Offset 6F would have previously been 9F, 8F or something else). Hit Set.
Your idle temps should now start falling.
You would have to do this hack/tweak everytime you rebooted your computer if it wasn't for WPCRSET.
- Go to directory and run "WPCRSET.EXE"
- Look at the top of the window: Enable select "Start" and make sure Device is on "enable"
- Then click Add. Enter 6F for the register, and 1F for the data
- Click Ok and you'll be prompted to restart.
Once, you rebooted, open WCREDIT again and see if the 6F register is still on 1F. If it is, then that's it..You're all done.
Here's a Screenie of how it should be:
This only brings your idle temps down, and not your full load temps
It should work for all nforce2s, and use at your own risk
Check your nf7-s for CPU Disconnect. Most other nforce2 motherboards do not have this feature in the bios...so this tweak might prove useful.
READ THE WHOLE THREAD BEFORE TRYING THIS!
If you run a Distributed Computing project...then obviously this would be of no use to you

It activates the C1 (and maybe the C2) function Athlon XP CPU's support. Most mainboard brands have this feature as an option in the bios you can enable and disable. I just found out that EPoX doesn't have that feature. So what you're doing is just using a direct reg tweak to activate it. It's not like you're forcing anything, the Athlon XP chips are made to support this feature so it shouldn't do any damage.
When the CPU is idle the mainboard will send a command to the CPU that will cause a part of the CPU to be deactivated (and therefore not produce any heat). That's why this tweak only works on the idle temp and doesn't change anything on the load temp. Ofcourse as soon as the CPU power is needed the deactivated part will become active again, so it should have any influence on the performance of the CPU.  
Strangely, my full load temp has decreased 6º C degrees too.
