Ok boys and girls, I find out how to disable Intel P4 thermal monitoring rpm, in short: The fan goes FULL SPEED no matter what, from 2600 rpm to 3668 rpm. Nice? Another 2 degrees lower. Very easy to do, No Soldering nor Major Operation.
Warning: Read my explanation carefully and make sure that you get the idea of what I am writing about.
For Intel HSF P4 - 1.6A & 1.8A:
1. Take out the sticker out (slowly) and you want to stick it again.
2. There is a "peep" hole, and if you look inside or view it from the side angle, you will see a hole on PCB that filled with solder. Yes, a hole that filled with solder. Diameter of the hole is 3mm
3. Look closely on that particular hole and follow the trace, it will connect to very small cube resistor (black color, with 2 metal edges on both side, the size 0.5mm x 0.5mm x 0.9mm). The "soldered" hole and the cube is within 2mm area, so you won't miss it.
4. Clean the cube/resistor with toothpick and alcohol, rub it...rub it... yeah, until both metal edges shines again.
5. Get a paint or pen conductor (the pen that used to connect AMD L1 & L7) and smear it around the cube. Yeah, quite a lot until both metal edges are covered with paint conductor.
6. Put the sticker back on, and Voila.... The RPM goes another 1000rpm.
For Intel HSF P4 - 2.0A & 2.2A:
1. Take out the sticker out (slowly) and you want to stick it again.
2. Near the cable entrance (black, green, yellow), looking inside at 1 o'clock, you will see a hole that filled with solder on PCB. The diameter of the filled hole is 2mm.
3. Look closely on that particular hole and follow the trace, it will connect to very small cube resistor (black color, with 2 metal edges on both side, the size 0.5mm x 0.5mm x 0.9mm). The "soldered" hole and the cube is within 2mm area, so you won't miss it.

6. Put the sticker back on, and Voila.... The RPM goes another 1000rpm.
For Intel HSF P4 above 2.2A, please observe the fan, and you should find the same things: A hole filled with solder and small cube resistor.
Secondly, there is a "decoy" underneath the PCB. A small cube sticking out from PCB, facing towards the Fans. THAT IS NOT thermistor!! Leave it alone.
