content: I fried a power transistor because I forgot I needed to heatsink it. Where can I get a heatsink / fan combo like this in the picture? These would be perfect for my application but I can't find them on ebay. Only cpu fans..Sent from my SM-G900P using Tapatalk

content: That is an older CPU heatsink/fan combo he just drilled and tapped holes in for the transistors.

content: Chipset and CPU heatsink/fan combinations can be had pretty cheaply even brand new, a bit of modification with a drill and screw can see you right.Have a look in whatever your nearest computer parts retailer is at cooling solutions, not just CPU but also chipset ('north bridge' , 'south bridge', 'vga' etc). Chances are you'll find something you can modify easily to suit your needs for just a few dollars.

content: That could be a Dell server heatsink. Browse eBay...I like CPU heatsinks... small enough, good performance, cheap, and it's recycling e-waste.Electronic Load - up to 240Watts

content: here is an example:http://www.ebay.com/itm/100x97x14mm-Aluminum-Heat-Sink-for-Computer-LED-Power-IC-Transistor-H175/221662333191?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D33430%26meid%3Dc8901f8960ec4022986ebe8f5f63a4c8%26pid%3D100005%26rk%3D5%26rkt%3D6%26mehot%3Dfs%26sd%3D321811779023just cut the heatsink, file it a little bit to make remove any sharp corners after cutting and make it straight, sandpaper it a little bit, drill & tap holes for the fan and your transistors and you are good to go.

content: Just know what to search for on eBay. For example, searching for "heatsink" won't get you anywhere useful.But, searching "xbox heatsink", "server heatsink" or "northbridge heatsink" gets much better results.Heatsinks with heatpipes are very effective, but only up to the a certain point. Then they flat out very fast because the heatpipe is often the only mechanism of transfer to the fins. As opposed to natural convection where it starts with a solid block fanning out in thinner and thinner fins.I can share a socket 775 template for eagle if you'd like. (this one: 66H080000-046)
