Customer Comments

  • How much heat does this sink? I would have bought it if I knew!!

  • What are the dimensions? Will it fit to a 40x40mm Peltier?

  • Any idea how much this weighs?

  • I was able to find this part on Digikey after some digging. Considering how long this item has been disabled, please see below where you can get this part:

    http://www.digikey.com/product-detail/en/RA-T2X-25E/RA-T2X-25E-ND/2416487

    Keep in mind this is the 1" high version. There’s several in the series that have different heights.

  • Could this be used to get the Peltier cooler here down to around 30 deg. F?

  • Is that hole threaded?

  • Hello, is it possible to take this heat sink to a band saw to reduce the 7 cm dimension down to 5 cm?

    • band saw may be too powerful, a diamond blade on a dremel is plenty or a hacksaw with metal cutting blade.

  • Do you guys have a eagle footprint for this?
    Do people make footprints of heat sinks?

    • Yes and Yes. It is part of the SFE eagle library and is also shown in the audio amplifier kit below.

My friend couldnt even kill it

I have this crazy physics friend that decided to make a plasma speaker on his own. He had a mosfet that was able to source RIDICULOUS amounts of current. He had at least 150W going through this mosfet. He was able to run his lightning arc for several minutes straight, the whole time without exceeding the max temperature of the mosfet. Now, I wouldn’t recommend doing this (we got burnt on the heat sink, but the $12 mosfet was ok so its all good), but this is a durable highly effective heat sink!
