    RAM heatspreaders largely ineffective?

    http://www.theinquirer.net/?article=29598

    Think I saw a similar article on Toms or Anandtech recently.

    erm, you saw it on hexus

    Though, in the big scheme of things, a couple of extra quid for 4Mhz is probably about as cost effective you can get with overclocked high end PC's.

    Thay can also be helpfull when handling the memory instead of trying to just touch the edges of the pcb.

    Yeah i agree Dave - i'd prefer them for that alone. I wouldn't pay more for flashy spreaders tho..

    Adding a heat-spreader doesn't significantly increase the surface area from which heat is dissipated (unless it has fins/serration et c.) and adds two more thermal interfaces between chip/adhesive and adhesive/spreader. Factor in imperfect contacts and stagnation points (where there's no contact between heat source and heat spreader and no air-flow either) and it becomes a wonder that people use them at all.

    The most effective way to improve cooling (where necessary) would be to attach individual heatsinks to each chip on the PCB with a good-quality thermal epoxy.
