Introduction: Better Thermoelectric Cooler/ Heater
How to get better cooling / heating with a $20 on sale Travel cooler / Warmer from Walgreens
And remember to easily view all the steps add ?ALLSTEPS in your adders bar at the end.
Step 1: Open It Up
Take the side panel of that covers the fan/heat sink. 4 Screws
Step 2: Get the Size of Fan
Measure the size of the fan (this one is 92mm)
Step 3: Go Shopping
Look online or your local computer store for a hi airflow fan but remember the more air flow the louder it will be. ball bearing fans are louder but the lubricant in them degrades vary slow (long life). Sleeve bearing fans are quieter but the lubricant in them degrades faster then a ball bearing fan.
And if you don't want to have to mod the side panel don't get a fan that is thicker then the one it has
I found a fan at newegg with over 100cfm (cubic feet per minute) that it moves but it is at 56 dBa (decibel)
Step 4: New Fan Installation
Installing the new fan. Remove old fan by unscrewing the screws.
Now for the wiring (i don't no how to solder so i just used wire tape)
Cut and strip old fan wires (leave like 1 in on old fan if u want to use it again)
Then cut the wire on the new fan Connect the red to red and the black to black tape with wire tape.
Screw the new fan to the heat sink.
Step 5: Close and Test
Cut the side panel if you need to for the thicker fan.
Screw the side panel back on and fit all the wiring in side.
Plug in and test
Now it should cool down a lot faster and with more air flow it will have to be cleaned from time to time.
Step 6: Other Ideas
Increase the voltage to the thermoelectric thing.
Add a fan speed control.
Put a internal fan to move the inside air.
Cut/Drill more holes in the side panel.
