Use the included NA-CW1 wipes or a paper towel moistened with isopropyl alcohol to clean. If slight residues remain after cleaning with NA-CW1 wipes, you can use a paper towel or tissue to polish. However, such residues are of visual concern only and will not impair performance. Also see our video tutorial on how to use NA-CW1 wipes. If you need further NA-CW1 wipes, please purchase the NA-SCW1 set (20 pieces).

Both our NT-H1 and NT-H2 are very easy to apply and generally don’t need to be spread out manually on the CPU. However, our recommendations differ slightly from paste to paste and from CPU size to CPU size, so please refer to our product manuals and video tutorials for detailed recommendations:

While there are some standardised methods for testing the thermal conductivity or thermal resistance of thermal compounds, they do not always guarantee comparable results. What's more, many vendors have started to claim thermal resistance or thermal conductivity specifications that appear simply unrealistic in the light of standardised testing. Last but not least, real world performance of thermal compounds is affected by various other factors such as spreading properties, bond line thickness, mounting pressure or contact quality, so even if there was a common and reliable industry standard for testing the thermal conductivity or resistance of thermal pastes, it would not give customers a clear indication regarding the performance they can expect. For these reasons, Noctua has chosen not to publish specifications for thermal conductivity and resistance. Taking part in a game of claiming exaggerated specifications is not an option for us and we neither want to give specifications that, in the context of this practice, could appear misleading. Instead, we prefer to let independent reviewers judge the performance of our thermal compounds versus competing solutions in order to help customers in making an informed buying decision. Please refer to our standardised comparison of NT-H1 vs NT-H2 and to our review database for independent tests.
