Scythe Ultra Kaze 120mm Fans
You can see from the included graph (below) that the Scythe Ultra Kaze Fans certainly provide extra static pressure. So much so in fact that the S-FLEX fans really start to pale in comparison.
You can see from the free air flow chart that the Scythe Ultra Kaze fans facilitate more airflow than any of the S-FLEX variety, which can be directly attributed to their increase in CFM. However, in defence of the S-FLEX fans they are designed to provide a near silent experiece and reasonable cooling capacity...something that they do quite well. The S-FLEX 1600RPM fan performed very admirably by just coming in under the Ultra 2000.
For the cooling performance part of the review I have included this chart to show the temperatures recorded by our test setup. All of the Scythe Ultra Kaze Cooling Fans outperformed the S-FLEX fans by a considerable margin. The Scythe Ultra Kaze provided the best cooling performance which was to be expected at around 133CFM, but at 45.90db(A) your ears know it. However, running the Ultra Kaze at 7v reduced the operational noise quite considerably without too much of a performance hit.

Across the board the Scythe Ultra Kaze Cooling Fans consistantly provided better results. They are a noisier option than the S-FLEX fans, but the performance results are exceptional and cannot be ignored.
Let's head over the page to see how well the Scythe Ultra Kaze Cooling Fans performed as a whole...
