Enzotech RAM-Kühler BMR-C1 High Profile - passive > 50 available in stock
You can buy them direct from Enzotech. I ordered a set (which is meant to contain 8 heatsinks). They cost 16.99 USD plus shipping plus a 3% Paypal fee. That makes them a bit more expensive than yours.
I believe the larger copper heatsinks are made by a company Enzotech based in California and the SoC heatsink is in fact intended for graphics cards. Its known as a BMR-C1 (14x14x14mm) with the fins/pins arranged in a 5x5 grid. They offer a multipack of 8.
This website lists newegg as a seller as noted earlier in poppageek's earlier post. Unfortunately newegg is now out of stock.
[EDIT] I just ordered a set from sidewinder. My 4 Pi3s in the PiVE are running around 59C and a Pi3 in a long tunnel with mSATA disk is running around 63C. All are crunching 4 concurrent WUs and are in the same room with an ambient temp of ~79. Its only going to get hotter so I am thinking that I will also need to employ heat syncs. It certainly can't hurt. Interestingly enough a Pi2 in a tunnel crunching 4 concurrent jobs in the same ambient temp is ~40C (no heat syncs either).
Yeah. I have a Pi2 in a closed case, has holes for CPIO amd camera and display ribbons, and a heatsink. No fans. Not overclocked. 58c. Not needing fans has great appeal. Everything seems so much easier as not much left to fail without them. Assuming no more SD problems. Wonder if the Pi can be underclocked?

LOL never dawned on my lightning fast, razor sharp mind to check the manufacturer. Good info thanks Mark.
I note that your fan is a 3 wire. Are you regulating rpm or just using the black and red?
The Noctua fan kit comes with a 2 to 3 pin adapter which I am using. I expect they are just using red and black wires, there is certainly no speed control when connected to the GPIO pins.
There was an add-on board for the Pi that provides fan control called the PiCoolFan however according to ModMyPi its been discontinued.
For those waiting for a PI Zero, this might be interesting: It was officially announced that production of the Pi Zero was restarted. The new batch of Pi Zeros will have "a (much requested) new feature", "but not WiFi". What could that be? 1 GB RAM? Battery management & charging logic?
Today I received some BMR-C1L heat sinks (14x14x9). Similar to the ones poppageek is using in his stack (I think his are 14 high). They are all copper. I placed one of these on a PI3 in a tunnel with an ambient room air temp of 79-80F (it won't get any better - summer is here) and achieved an immediate drop in temp of about 8-10C (was running 61-64C before heat sinks now ~56C with heat sinks). I believe this is a satisfactory drop in temp considering ambient room temp. This is while processing 4 concurrent WUs. I chose this tunnel because its Pi3 runs slightly hotter then the others. I will upgrade the other 4 Pi3s to have this same heat sink tomorrow.

CosmicPi looks very interesting, if only the price point was a bit more moderate...
Also the Pi-monitored cat running wheel is nice:
