Heatsink or not for 09/10 DIMMs?

    In the 2008 and earlier models, FB-DIMMS used huge fins for cooling, but my 2010 came without any heatsinks. The 09/10 lower section seems to have superior cooling for the CPU/RAM tray with front and rear wind tunnel-esque fans, but should I invest in some heatsinks for the dimms to maximize performance?

    FWIW, My CPU temps have been running around 30-35C and intake/exhaust fans spinning to around 600-700.

    my 2010 quad has kept its ram sticks at 95 to 100f slots at 93 to 97f.

    I use three 4gb sticks with no heatsinks. Had machine since oct. that is 34c to 38c



    translation 60c would be a bit high so I don't even think about 38c

    My 2010 Apple original 3x1Gb came nekkid but the 3x4Gb Hynix came with simple heat-spreaders.

    I don't think adding heat spreaders will help maximize performance in any noticeable or measurable way.

    I would think if you use your machine with tons of handbrake every day and have the ram and the cpu close to pegged hours on end heat spreaders may help.

    Heat spreaders are unnecessary unless you're overclocking (not likely on a Mac) or experiencing kernel panics due to poor cooling.
