Raspberry Pi Ultra Thin ICE Tower Cooler

If you push your Raspberry Pi to the limits, then you are going to come across issues relating to overheating. While sticking passive heatsinks onto the chips is enough for most, serious overclockers are going to need serious cooling.

But what's the best possible cooler out there? Well, I've tested about a dozen of the most popular Raspberry Pi coolers, and narrowed the field down to one -theRaspberry Pi Ultra Thin ICE Tower Cooler

Fitting the Ultra Thin ICE Tower Cooler is easy.

1. Fit the thermal pads

Apply thermal pads to the four chips on the board (the thermal pads have a removable film on both sides that needs to be removed or your thermal pads won't work and will cause more overheating).

2. Attach the cooler

Screw down the fan using a 4.5mm nut driver (not included, you can use your fingers as you don't need to overtighten these). The driver I used here came from the excellentiFixit Pro Tech Toolkit .

3. Fit the base

Screw down the acrylic base plate. The screws thread into the brass stand-off screws used to attach the fan.

4. Wire up the fan

Connect the red wire to GPIO pin 4 (second pin along on the top row), and the black wire to pin 6 (third pin along on the top row).

If you plan to use fan controlling software, the blue wire attaches to GPIO pin 6 (fourth pin along on the top row).

5. Change the orientation of the fan (optional)

The fan can be removed and reattached in a different orientation if you need to change the position of the wires. This is easily done by undoing the four screws holding the fan down and refitting it in a different orientation.

How good is this cooler?

Good.

Very good.

I used the stress-testing tool Stressberry to push aRaspberry Pi 4 Model B to the limit. Yo can get more information on how to install and run Stressberry here.

I carried out a number of stress tests, and here are the output charts showing how hot the Raspberry Pi got.

The first test is of an uncooled Raspberry Pi running at the stock speed.

Peak temperature: 67
