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: Finished: 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!!
