    I am new owner of Haswell i5. As this is non-k version oc is not option.
    So i decide to go opposite and make CPU to run as cool as passable and as bonus effecting noise from CPU cooler.

    But first i change few CPU settings in UEFI forcing it to run full turbo 3.7GHz instead of 3.5Ghz on all 4 cores when under load. I using aftermarket cooler Silentiumpc Fortis HE1225

    To stress CPU i am using OCCT with AVX on
    So far i change only VCORE down to 1.055V from stock 1.12V(MB auto)
    It dont change idle temps - ~32C (!ambient temp ~23C)
    But it change Max temps from 67C to 59C after 1h stress test
    Temps during longer gaming sessions look even better. They are ~53C

    Can i go lower with voltages, how low can i go, does changing others voltages will have effect? Is this is worth trying to go lower or effect will be minimal??

    You can lower voltages but it also decrease stability

    set the uncore ratio at 35 or lower. that setting increase stability, reduce the vcore needed when overclocking and has a minimal effect on the CPU performance.

    My CPU only need 1.157 to do 4.5ghz with the uncore ratio at 35.
