NT06-E cooler from SilverStone has an excellent construction quality. But unfortunately this quality did not translate into performance. Even with a high airflow fan, it performed as bad as the worst coolers we tested with this methodology.

We understand that maybe the position the cooler was installed has contributed to the bad results. However the position we installed the cooler is exactly the same as pictured in the manual. Besides that, it was the only possible way we could install on our testbed computer, so we have no reason to discard the data. So it is possible that if it is installed in a different position it will show better performance: in our attempt to change the position of the case it permormed a little better, but not enough to get even close the coolers we gave award seals to.

NT06-E is not an inexpensive cooler and you still must consider you have to purchase a separated fan. It is not easy to install too. So, there is only one possible conclusion: forget about buying this cooler.
