BACKGROUND:
To many this heatsink could just be a used lump of pure Copper but I am big on reusing or repurposing old electronic components and hardware, particularly from the point of view of sustainability.
Sustainability far more than NOT burying waste material back into the earth but consciously recognising the energy expended to create the item through it's various "stages" in life, beginning with the raw materials being extracted from the earth, processed, finished and then fitted into equipment - every single step used energy which is referred to as embodied energy.
To give an approximate representation of how much energy was used in the WHOLE production process of an item, I have created what I refer to as the Ee (Embodied Energy) value, measured in Mj
The Ee value is an approximation only and usually measured in Mj.
Coming up with an Ee value is an attempt to take into account the energy used for extracting and processing of the raw materials, manufacturing of the component, distribution of the component(s) and final assembly of the component. In fact the measurement of Ee can become extremely complicated and technical, many tertiary institutions are involved in this specialised field of science.
I have used various reliable sources online to arrive at approximate Ee values, these are approximations and the sole purpose is to raise awareness of the extraordinary energy consumed in the creation of various electronic components and hardware - it may give you cause to think twice before wasting all that energy and burying it in the ground, with the possible side-effects of poisoning the environment due to leeching.
HERE is a page I have created which gives some tables and more detailed information about specific Ee values for different materials plus a link which you can use as a starting point to investigate Ee for yourself.
This compact but highly efficient heatsink was extracted from the excellent RSA Scorpio X security applicance, unfortunately the PSU had failed and the equipment had been upgraded in any case. This is one component you cannot miss, standing large and impressive, helping a Celeron CPU keep it's cool!
Think outside the box with this one ... this pretty hefty lump of copper (with a nice fin matrix topside) could well be pressed into service keeping other devices cool, not just a CPU.
HEATSINK
Material: Pure Copper (not an alloy)
Source: most likely to be USA, as the equipment was USA assembled but I cannot confirm the source of this heatsink.
Part # Unknown
4x corner holes predrilled for mounting and I am also supplying the original spring loaded compression bolts - these can easily be removed (retained with a circlip) if you have alternative means of mounting available.
Thermal characteristic specifications are unknown, unfortunately
COSMETIC CONDITION:
USED
Clean
NO physical damage
NO damage to the topside fins (all are straight and true)
Clean underside, all previous thermal grease has been removed.
DIMENSIONS:
External: 92mm length x 92mm width x 22mm height
Multiple thin fins topside, great for blowing or sucking a bit of air across the top
WEIGHT: 690g (Yes, this is HEAVY for it's size)
This heatsink has now been wrapped in bubblewrap and then placed within a sealed, clear plastic packet waiting for the opportunity to "cool down" other equipment OR if you had a suitable furnace, melt it down to create something new!
