Test Results

TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.

We already know that the NH-U12DO loses a small amount of surface area at the fins and the loss is visible in our testing when compared to the NH-U12P. A couple of millimetres here, a couple there, they all add up when multiplied by the thirty five fins. Still, we will not let four tenths of a degree hold us back from taking advantage of the gains associated with reducing the overall size.

When compared to the latest coolers we tested, the Noctua NH-U12DO fairs very well. Noctua has yet to enter the H.D.T. market but still fairs very well with these types of coolers.

One area that Noctua has always excelled in is their fan technology. The NH-U12DO completely blows away the other coolers we looked at this past month. The reading at idle and load are exactly the same as the NH-U12P enthusiast cooler, showing that the heatsink produces little turbulence that is audible.
