Ok I have been looking to do this for a long time. My MBP runs very hot even when the internal fans are at 6000rpm. During full usage of CPU(100% or over), the temperature goes from 99-105C. My cooler master cooling pad always sit under my laptop so imagine without the pad, it would go higher than 105C. And so here's the solution for me.

Materials I used:
1. Cardboard box
2. 1x Large Computer Cooling Fan (2000rpm)
3. 2x Small Computer Cooling Fan (1200rpm each) - From the same cooling pad
4. Molex connector cable (AC-DC)

Fans installed in three square holes, double sided tape around inner squared holes to hold the fans in place.

MBP sitting on my cooler master cooling pad but without fans. Fans are taken out for the two smaller cooling fans. The pad lifts the rear portion of laptop, holding the laptop vent to the direction of the three cooling fans. The cooling pad surface is aluminum, maximizing cooling ability!

The cooling pad.

Everything is set up and ready to connect the cables: Power On

Cardboard side vent to provide sufficient air flow into cardboard.

A look of the insde, rear vent on the left for maximum ventilation:

Fans now visible when laptop screen is up!:

Cooling Performance Result at 20C Room Temperature, Default Internal Fans are 2500rpm:
At Full CPU Usage - 90C Maximum Recorded (6000rpm internally)
Light Usage - 43C Lowest Recorded
Writing this post - 50C - 51C

There's my set up! Basically up to 10C drop in temperature. I am so far very pleased with the results!!
 
I'm curious how your MBP gets so hot. Under full load, mine SR MBP gets no where near that temp, maybe 90 tops but even that was maybe once or twice when the vents are blocked.

Based on this it seems like your MBP probably have a bad case of thermal paste application from the factory. Or its dirty vents.

Vents are clean for sure. Actually my logic board got replaced from Apple a week ago due to video chipset failure (8600GT). And yea mine is SR too. 90C is easy, watch something HD on youtube, and it will go to that temp. I know about the thermal paste but hey under normal usage, I am no where near 70C, only when the CPU gets heavy will go up to 100C:)
 
Oh my GOD!!! you do have too much time on your hands :eek:

still... whatever cools off your balls.. or in this case your :apple: 's
