Measures and results
Appraisal
This whole copper version is the champion of the Zalman family and is one of the five most efficient coolers at 12V. It is even in first position at 5V, way in font of the XP120. It is also less noisy than the XP120 with the Papst ! It is 2.5°C better than the 7000 Cu version and almost 5°C compared to the 7700 AlCu at full load for the whole ventilation range. This result is really excellent! The voltage isn’t the only aspect, and the XP90C + Papst duet provides better performances at 7V with a lower noise level. In the end, this cooler is an excellent choice for silent computer enthusiasts who are also seeking excellent air cooling performances.
