    So i recently got my i5 quad core

    There is a slight crackling from the HDD, its nothing big
    There is a slight buzz when changing brightness, also dosnt bother me, no grey banding or yellow tint

    Also

    Why is the i5 quad core so cool? after 2 hours of sc2 its temp reach a max of 68 degrees, and the fans were dead quite in windows, dont understand it :p

    It could be that the CPU isn't running at its max because the GPU is bigger bottleneck. Also, I'm not sure is SC2 multicore but I think it is. However, you shouldn't worry about it being too cool :p

    still, i just think its weird, now its idling at 39 degrees celsius says istat menus, i have had several intel cpus, and they tend to be hot.

    But ofcourse i dont complain :)

    Hi,

    I bought an iMac just before the refresh and I also have an noise coming from my HDD.
    To me it sounds like a hungry stomach. When nothing happens it not there but during startup or starting up a program I can hear it.

    What kind of HDD do you have? I have a Seagate 1TB.

    Cheers.

    Im coming from a 2009 macbook pro and 2007 macbook pro, and always found the CPU to run from 50-70 deg celcius. on my 27" i5, cpu seems to stay below 50 but gpu diode gets to around 65-75 play starcarft and the top of the imac gets very hot (I know, its acting as a huge heatsink)

    are you getting the same?
