For the purposes of our tests on the synthetic temperature test platform, we used a single 92mm x 92mm low-noise Zalman fan set at 6" and 12" distances from the TS Heatronics NCU-1000 heatsink to replicate typical computer case air flow in an impingement fashion. As we can see by the initial results, the stronger the airflow, the better the heatsink did indeed perform. For a passive cooler it looks as though we may see some fairly good results from the NCU-1000.

Looking at the final rise above ambient temperatures we can instantly see that with relatively strong passive airflow, the TS Heatronics NCU-1000 would prosper very well as a Pentium 4 cooler (Scythe handles the online retail of this Japanese heatsink). The results of the test with the 92mm fan placed 6" away may be difficult to directly emulate within a case considering the number of different variables that exist which can impede, or improve good ventilation, but none the less, the results are impressive.

As a passive heatsink, the NCU-1000 certainly has the means to perform very well indeed, and is obviously only limited by the airflow it receives within the computer enclosure. For the second test, we moved the 92mm Zalman fan back to a distance of 12" away from the NCU-1000, and watched what happened to the temperature reading on our digital thermometer....

Surprisingly, the temperatures only rose about 8-9 degrees Celsius. Considering the drop in airflow, the temperatures we see here for the 12" distances are still quite remarkable, though not as impressive as in the 6" test.

Ultimately, the TS Heatronics NCU-1000 is a passive cooler that is intimately tied to the benefits of an actively cooled computer chassis. The better the airflow from the front of the case, up to the powersupply, the better the NCU-1000 can perform. Thermal performance ranged from average to pretty good in our tests, an in each test that was without a fan directly mounted to the heatsink. Very cool indeed.
