I have often thought it would be nice to have a small heatsink for the raspberry pi if you were going to overclock it. While I was ordering my OBD-II uart adapter from DFRobot I noticed they carried small pure copper heatsinks for the Raspberry Pi. They are only 99 cents. I figured “that is just too cheap not to try it!” So to the cart it went. The heatsink showed up yesterday. Total time in transit from china was a little less than three days.
It comes in a little baggie
All you do is remove the plastic strip from the back and press it on top of your CPU
It does indeed transfer heat rather well.
So I took the time to measure the temprature of the CPU while running Wolfram’s Mathematica. I had it calculate the 2,000,000,000,000 prime. That pretty well hammered the CPU for several minutes. On the Raspberry Pi with out a heatsink running at 900 MHz it read 99 degrees Fahrenheit. It also read 98 degrees on the back side of the board.
On the Raspberry pi with the heatsink running Mathematica performing the same calculation it measured 83.5 degrees Fahrenheit and it read 82 on the back of the board. The heatsink read 83 at the base and 80 degrees at the top of the heatsink.
All measurements were taken several times with an infrared thermometer and averaged. It’s worth noting that there was less than a half degree of deviation between measurements.
So from these rather simple and unscientific tests I can at least say that this heatsink does indeed work and is certainly worth the 99 cents it costs.
You can get this heatsink strait from their website.
And here is my disclaimer. Although I have written some very favorable reviews of DFRobot products as of late and there will certainly be a few more shortly as I have time to work with the OBD-II uart adapter, Nixie Tube module, and some of their gas sensors, I have not been compensated in any way nor have I received anything from them directly or indirectly. These are strictly my opinions. If you find value in them great and if not that’s fine too. If you are like me you tend to read up on a product as much as possible before making that final decision to purchase a product. I have not been disappointed in any way by their products and thus feel great about recommending their products as not only well built but also cost effective and typically well documented and supported. I also have always found DFRobot products to be extremely well designed which I appreciate a lot as an engineer!
