We recently had a surplus of hard drive heat sinks at work from old drives that were being sent out for destruction/recycling and I snagged a few of them on the way out the door. This weekend I wanted to have some fun and decided to turn one of them into a coffee warmer with some spare parts and two spare Block Eruptors I had laying around.
The original unmodified heat sink



I drilled a hole between the two USB connectors and expanded the original outer holes to give sufficient clearance for the zip ties


Added standoffs to each of the corners

Prepping for final assembly

The two Block Eruptors attached to the heat sink with thermal tape

Added zip ties for strain relief


Hashing away

Results:
The heatsink works a little too well and only gets uncomfortably warm on the top of the heatsink, but there is plenty of room to add another one later.
