Laaaarge Heatsinks
3 Attachment(s)
This is a large heatsink with cross section size of 300mm x 50mm. The base thickness is 10mm, easly beat most of other heatsinks you can find on the web. If you are looking for HS for class-A, this is second to none.

The standard height are 85mm/115mm/125mm/145mm. Custom height are also available.

Price example: 115mm height type, $40/pc, weight 1.7kg, will takes $25 for air+ground shipping to USA or $30 to Europe:mad:

Shipping 2 or more will save a lot shipping costs. Hope somebody can start up group buy of such heavy products.

Looking at the nice boxes on your homepage, the missing part is the thermical data on the heatsinks...

Is there any simple method to calculate or measure C/W of a heatsink?
