To replace the AMD orgine cooler comes with the Phenom II X4 extremely noisy.
This cooler is mounted relatively easily. No conflict with the memory modules (normal size) but that's all right.
Especially a great silence at maximum speed and near-silent at the minimum speed.
And this is not done at the expense of efficiency, CPU temperature is lower by at least 10 ° with respect to the original cooler.
