Today I am adding some heat sinks to the Raspberry Pi Cluster and why you might want to.<\/p>\n

Adding some Heat Sinks to my Raspberry Pi’s<\/h2>\n

One of the things we can do to reduce the temperature of the Raspberry Pi CPU’s is to add a small heat sink. This will draw the heat away from the SOC package (the black squares) on the board. The heat sinks are normally made from a highly conductive material such as aluminium. They aim to have a large surface area to release the heat into the surrounding air.<\/p>\n

I purchased a number of small heatsinks for the Raspberry Pi’s, each pack had three heatsinks. For all Raspberry Pi B’s newer than the Raspberry Pi 1 B+ you will only need two. The older Raspberry Pi’s have a larger voltage regulator\u00a0which can get quite hot which is where the third can be seated.<\/p>\n

Each heatsink has adhesive tape on the bottom to allow easy seating on the SOC packages. Below is two images showing the placement of the heat sinks on both a Raspberry Pi B 1 and B+<\/p>\n

Why I am adding some heat sinks<\/h2>\n

For some of the experiments I want to do with the Raspberry Pi Cluster I am planning to run the nodes at 100% CPU usage. Most CPU’s will be rated to run at 100% usage at a specific maximum temperature. Normally most CPU’s, when run for a long period of time at 100%, will start to exceed this recommended temperature for safe working.<\/p>\n

Some CPU’s will reduce their speed to cool themselves down having a thermal cutoff. However this will reduce your processing power and therefore the power of the cluster. One of the things you can do to reduce the temperature is install a fan or heat sink to the processor.<\/p>\n

In the future I may look into the difference between running a Raspberry Pi with and without the heat sinks to compare the temperature reached. In addition the Raspberry Pi 3 can reach much higher temperatures due to its faster processor and increased number of cores.<\/p>\n","protected":false},"excerpt":{"rendered":"
