  2. Cheap quick good heatsinks

    Posted by Aditya on 29th Nov 2015

    Great to be able to find parts for our project locally but still be at reasonable prices (unfortunately harder and harder to do for a lot of things)!

  3. very helpful staff, super fast shipping, great product

    Very glad I came across Heat Sink USA. Great product, great service, incredibly fast delivery.

  4. OK - But...

    Posted by Unknown on 9th Aug 2014

    The machining work did not meet specifications.
    While the extrusion is of good quality, I paid
    additional for an area to be machined flat.
    "Surface error (flatness) to equal or better
    than farside (flat side) of extrusion stock."
    Two of the five pieces have significant tooling
    marks which I hopefully can lap-finish flat. The
    other three - I will have to have re-machined
    because of the significant surface ripples left
    by the machinist.

  6. Great product

    This heat sink will be used in a 2M linear amplifier and the heat sink forms the top of the enclosure. It looks great! Excellent machining and precise cuts.
