    Any way to add support for weight of CPU coolers?
    <hr style="color: rgb(0, 0, 0);" size="1"> <!-- / icon and title --> <!-- message --> With some new even heavier CPU coolers appearing on the market, I am wondering if they are at or over the limit of what a motherboard can support in a vertical position, even with a backplate as part of the design.

    Can the boards support a 3 pound heatsink device? Are there any published specifications on this? I am thinking specifically of a Gigabyte EX58 or EX58A board.

    Is it possible to add some physical support at the unsupported end of a tower-type heatsink?

    the motherboard should cope with all the latest coolers and heatsinks as im sure there built to a specific design and weight,the backplate should help support the cooler also so i wouldnt worry

    They seem scary heavy, but remember the motherboard is bolted down too, at the top.
    I wouldn't worry about it.
    When you tighten the heatsink bolts down, remember not to crank too hard.

    Ya the most dangerous thing is tightening down the heatsink bolts/screws to tight as this can cause the board to flex and make the mosfet heatsinks not make proper contact and can also damage the PCB itself.

    I think 700 grams is the documented limit, which isnt much really. But that was for 775 boards, I have not seen what is suggested as a limit for x58. I believe it is likely in the intel documents though, if you want let me know and I will look for you.

    If you are wanting to use a super heavy cooler like a copper TRUE I suggest you use those only in a horizontal setup

    I just bought a Fatal1ty cooler by Zalman and it is a beast!
    It weighs 918 grams. It says the maximum specified weight for a
    cooler on an Intel Socket 775/478 is 450 grams.
    It instructs to take special care when moving equipment that has a
    cooler that exceeds the weight limit. And of course that they are not responsible for any damage caused by the use of their heavy ass cooler!

    if mbrd is horizontal nps but there is a big moment of inertia or however you want to describe it.
    the side panel of my pc is a semi elastic material, but i would use something like a support attached between the topof the heatsink and the topside of the case.
    i feel it does move a bit off verticl due to the weight and for example if you accidentally dropped the pc it could rip the whole cpu +socket out of the mbrd because of the leverage.

    Any way to add support for weight of CPU coolers?
    Good question!
    The one I'm using is 800g
    Its on a older Gigabyte 1OZ copper PCB.
    It's been about 11/2 years now, and still tight.
    That 2OZ PCB should handle more weight.
    But the Heatsink and fan may be larger or set higher from the PCB too.
    I imagine there is alot to consider here other than just weight.
