Aluminum Mini Cooler Set These lightweight aluminum mini coolers, which you can use in many mini computer cards and electronic cards, especially the Raspberry Pi, are self-adhesive. Aluminum coolers will prevent the processor and integrated heat on the Raspberry Pi from reaching high levels, making the card more stable and long-lasting. There are 3 aluminum coolers in the kit and the dimensions of the coolers are

14x14mm SOC Cooler

9x9mm Voltage Regulator Cooler

9x9mm LAN9512 Cooler

The Cooler Set is compatible with all Model 2/B+/A+/B models. With Model B, it can be used in all three refrigerants. Coolant is not required for the regulator on the model 2/B+/A+ cards, so it is sufficient to use two of them, the processor and the LAN driver. The chip under the model 2 board is RAM and will not heat up, so there is no need to install coolant on the RAM
