New & unused.
DIY Generic Intel Socket 1155 / 1156 ABS plastic backplate with M3 threaded metal posts. G900 SY self adhesive tape pre-fitted for easy alignment.
No fittings, no modifications, no instructions but plenty of advice, read on!
But why "DIY"?
Because ... although this backplate WILL fit the motherboard (see photographs, below), not EVERY heatsink mounting kit is suitable.
I know, because my ASUS P8P67 PRO with a Zalman 1156 fitting kit didn't like something.
This backplate is pre-fitted with embedded metal, M3 threaded posts that poke approximately 1mm past the top of the motherboard.
Many (non-Intel) heatsink fittings like waterblocks etc REQUIRE that the four backplate posts protrude through the motherboard so that the fittings can align & locate correctly.
Others, like mine above, do NOT like these backplate posts to stick out above the motherboard. Instead, they require a perfectly flat motherbaord mounting surface around the backplate holes for the heatsink adapter to screw into. I had to modify my backplate by skimming about half a millimeter off these posts. Then the Zalman 1156 fitting kit worked OK and more imporantly it DIDN'T CRUSH THE MOTHERBOARD!!!
That is why I have called this item "DIY" ... because YOU have to decide if it will fit your heatsink fittings AND if you need to do as I have done & skim the mounting posts if necessary.
It is the Buyers' duty to read the auction description and these warnings before buying.
There are millions of combinations of PC enclosures, heatsinks & waterblocks & fittings. This backplate may be 100% suitable for your hardware BUT IT MAY NOT BE.
So, there is no possible way I can answer questions like "will heatsink fitting "X" work with this backplate on motherboard "Y" in PC enclosure "Z"? so please, do the research and if this item is unsuitable, DO NOT BUY.
This is the pre-existing CPU backplate on my ASUS P8P67 PRO motherboard (not included).
How the generic heatsink backplate uses the pre-installed CPU backplate ...
The generic heatsink backplate is moulded to press agains thepre-installed CPU backplate. This lifts the heatsink backplate away from minor components all around the heatsink backplate on the motherboard.
The generic heatsink backplate is lifted away from components.
Notice the gap left when fitted. This clears any minor components / solder joints because the heatsink backplate is lifted away from the motherboard by the moulded-in mounting post legs.
The generic heatsink backplate mounting posts.
The generic heatsink backplate mounting posts will poke through about 1mm above the motherboard. This is for fitting non-Intel, aftermarket heatsinks & water blocks that have 1mm thick attachment legs etc.
Some heatsink fittings fit flat to the motherboard and require that the heatsink backplate mounting postes poke through the motherboard so that the heatsink/waterblock is properly located.
HOWEVER ... other heatsink mountings differ!!!
My Zalman 1155 /1156 heatsink adapter (not included).
The legs of my Zalman heatsink adapter - as highlighted in the photograph below - are flat.
No good for a standard back plate as supplied, so my backplate posts (see last picture, below) must be skimmed to the thickness of my motherboard OR my Zalman heatsink adapter must be drilled out to allow the heatsink backplate posts to fit inside my Zalman heatsink adapter. That will allow my Zalman heatsink adapter to sit on top of my motherboard without pinching it.
For your motherboard, heatsink, fittings, adapter etc ... it's your choice.
My Zalman backplate skimmed (not included).
My Zalman heatsink backplate posts are skimmed in order to match the same thickness as my motherboard. So, when fitting my Zalman adapter my motherboard is not pinched and my Zalman adapter sits flat on the top of my motherboard.
