Well, I just e-mailed to find out what mb he used in his celeron 2 based review. Initial comments would be that his t-bird, which runs at double the wattage, ran a mere 11F(6C) over the c2 temps, which, quite frankly, is impossible. He should be at least double the change over ambient(the c2 is roughly 27W, versus 67W for the t-bird). (for example, he got 28F over ambient with the C2, he should be at least antother 28F(if not more) before his t-bird core temp)
Will know more when he responds with c-2 testing mb.
