I be reading up on coolers myself today and the one you have in your spec is not really recommended..as it only meant to work well went the fans are set to high speed...unsure if to change the cooler? any recommendations?
Don't bother with the H70, for the extra cost you get basically no improvement in cooling over a decent air cooler.
