So, what’s the best fan for your Megahalems? The San Ace 9G1212H101/9G1212H101 is the fan that meets the 50°C temperature over ambient criterion with the least noise. For a pair of fans, the Yate Loon D12SH-12 comes closest with a temp over ambient of 50.5°C without being too loud, but in general two fans make a lot more noise for only a little more cooling. It is clear that we must accept a trade-off between fan cooling power and fan noise. As usual with overclocking, there are no simple decisions.
