Airflow mod to loop air from the left to right side of the computer and out the power supply fan. My temps after running a demo for 12 hours went from 38C all the way down to 25C with an ambient of 23C.

You will need, 

• One 5015 12 volt blower
• two m3x20 bolts with nuts
• two m3 plastic self tapping screws (any length, longer is better)
• one noctua 40x20 fan
• one small zip tie
• solder/wire/heatshrink

1. Print the duct out of whatever you want at a high layer resolution, you will need paint on supports as in the attached picture. I printed mine on my MK4 with a .4 nozzle at .15 in Prusament PETG.
2. Assemble with the m3 bolts and nuts, the hole at the bottom is sized so the nut rests perfectly against a flat edge so you will not need to hold it with pliers. I used some long SMD tweezers to flip it upright and hold it in place to get it started. Use some needle nose pliers for the bolt at the top closest to the opening.
3. Attach the duct as seen in the picture using your m3 plastic self tappers.
4. Fit a Noctua 40x20 fan in the hole to leads to the right side of the computer, It will fit be patient.
5. Affix a zip tie in the shown position to hold the fan at an angle that points over the cpu/fpu.
6. Wire everything up.
7. Play games and watch demos.
