heatsink
Even though it is a 3 inch unit, the photo on your website does not clearly depict all three dimensions of the unit. Namely, the height dimension.

Good product / lousy shipping
Took over a week to deliver a pair of 24" sinks roughly 40miles via USPS. Not the fault of HeatSinkUSA - their products and service are the best. Just don't use USPS.

Excellent Quality
Was extremely pleased with this purchase. Needed 4 in order to use for an LED project for growing herbs, I'll share a link when assembled and final, used thermal pad (TIM) - the surface was in excellent shape, no re-surfacing required.
Thank you and I've purchased a 12" as well for a similar project for Cucumbers and short duration vegetables which fruit. It will be awhile prior to having the project underway, but as soon as it is available. I'll post this link as well. -
