Why do you need to put a heatsink on your Raspberry Pi?
Reduce the risk of hardware failure because of overheating
The heatsink is a must for the overclocking
1x 14mm(L) x 14mm(W) x 5mm(H) SoC Heatsink
1x 9mm(L) x 9mm(W) x 4mm(H) Voltage Regulator Heatsink
1x 9mm(L) x 9mm(W) x 4mm(H) LAN9512 Heatsink
All heatsinks come with thermal tap attached at the bottom
Make sure the chip modules are free from dirt and grease
Peel the protective liner on the base of the heatsink
Affix the heatsink on the chip modules and apply firm pressure
? Addicore set of 3 heat sinks for the Raspberry Pi models B, B , 2, and 3. One large heat sink for the ARM processor and two small heat sinks one for the LAN controller the other for the 3.3V regulator
? These pure aluminum heat sinks include adhesive thermal tape for efficient thermal transfer to the heat sink providing additional cooling to the electronics they are attached to
? These heat sinks have profiles which are short enough to fit within standard Raspberry Pi cases
? These heat sinks can be used with other devices such as the Beaglebone to cool processors, regulators, etc.
