Raspberry Pi Model 3/2/B+ Copper Heatsink with Micro Fan

This was such a cute little fan I had to buy it.. You really don't need it, but if you like seeing how cool you can keep the chip, it is fun to try. Its a bit on the pricy side.The fan can be run at 3.3 volts (pulling 42.3 mA) or 5 volts (58 mA) on the GPIO pins. At 3.3 volts, it is nearly inaudible, even close, with a little other fan noise going on in the room. At 5 volts there's a noticable whine - not too bad if it was stuck under a desk or not right by your ear.Here are some numbers on how well various heatsink combos do in Canakit case with the cover off.This was running 4 seti@home tasks on a raspberry pi 2. No overclock (mine gets s@h errors with an overclock):No Heatsink -> 58.4 CStock Canakit H/S (short, aluminum fins) -> 56.8 CThis H/S (no fan) -> 55.1 CThis H/S (fan @ 3.3 volts) -> 46.5 CThis H/S (fan @ 5 volts) -> 40.1 CAdd a few degrees if you keep the top on the case - the case doesn't permit much airflow. It does fit in my Canakit case with the top on.I could do better with very large heatsinks (and using copper shims instead of the debatable thermal tape all these heatsinks come with), but so far, not with anything that remotely fits in the case.

Neat little heatsink fan combo for the RPI2. This type is not necessary for overclocking your PI but maybe helpful in high heat environments. Regular air conditioned rooms will most not need it.You'll need a case with some headroom to not interfere with the fan. The fan also makes a high pitched whine that you'll either need to insert a resistor to slow it down or the PI will need to be placed in an environment where the noise doesn't matter. But if you're slowing down the fan then you don't need this kit.Thermal readings from the board show this to be the coolest running PI2 of my collection without an external fan. This is mostly to do with the tall heat dispersal fins of the all copper heat sinks. Honestly, if you're in a high heat environment, the copper sinks with the long fins (or poles in this case) coupled with a decent case fan would probably work better. This fan isn't pulling in much air from outside the case so in a high heat environment, you'll need an open airy case or a secondary case fan.BOTTOMLINE:If you just want to overclock your PI2 in an AC room, just buy a cheaper heatsink combo with long heat dispersion fins.

I bought it to keep the processor of my Pi v2 cool as I stream constant video to a website, as kind of a high frame rate security cam. No crashes to report, but I didn't try it without the heat sink, so I'm not sure if it would have crashed. The fan works great though, plugs into the "always on" GPIO pins, so it's slightly annoying if it's in an otherwise quiet room. I would like it to come on only when the processor is working hard, so I get to do some programming (a good thing). It's exactly what you want in a raspberry pi component - works out of the box, but not QUITE the way you want it to work, so you gotta do some tinkering.

Connect this to pin 2 of the Raspberry Pi B+ (3.3V) and you will never have to worry about over heating your Pi. A little pricey but required if you want to overclock your Pi which is necessary for many applications. For asic mining on your Pi, it depends on what kind of case you have, ambient air temperature, and other external cooling fans you have. I think there is no better heat sink combination for the Rasberry Pi+ and it's worth it for peace of mind.

This is a must-have for anyone using the Pi, whether you are overclocking or not. I did solder in a  15 ohm 1/2 watt resistor  to take down the fan speed a bit since it is excessive and causes a slight high pitched whine. Even with the lower speed, I am overclocking a Pi2 at 1100Mhz and have not had any issues. my Pi still runs nice and cool.

It's quite and it work as advertised. The price is ridiculous, half the price of a RPi2, but for those that must overclock their Pi boards, the little fan may be critical to maintaining a stable and long lasting system.

Used this to overclock my model B+ more mhz so I could run a emulator with less chopiness.Worked as needed.

Its overpriced and the fan is to loud for how small it is. Most likely a defective fan. Also I bought a box of "ram heatsinks" the same size/about same or better quality for cheaper than they sell one of these..sold by ENZOTECH
