Scythe Ultra Kaze 120mm Fans
Testing
Published: 8th December 2007 | Source: Scythe-EU | Price: US$12.00 |
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.
The Scythe S-FLEX 1200 and 1600RP fans provided a reasonable amount of static pressure, but the 800RPM S-FLEX fan found the going tough and failed to deliver above 0.09 cmH2O of static pressure.
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.
Here is where the higher RPM Scythe Ultra Kaze's really start to shine. You can see from the 'Radiator Air Flow' graph below that only the Ultra Kaze 3000/ Ultra Kaze 2000 and the Scythe S-FLEX 1600 RPM fans were really the only 3 fans to be able to push enough air flow through the radiator in order to make the vane on the Anemometer register airflow. The S-FLEX 800 RPM fan was was left behind completely by failing to register any air flow through the radiator.
Cooling Performance
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.
| Voltage (v) | 7v | 7v | 12v | 12v |
| Radiator probe config | In | Out | In | Out |
| S-FLEX 1600 | 33.3 Deg C | 32.3 Deg C | 31.8 Deg C | 30.6 Deg C |
| S-FLEX 1200 | 33.4 Deg C | 32.9 Deg C | 32.3 Deg C | 31.2 Deg C |
| S-FLEX 800 | 36.1 Deg C | 35.7 Deg C | 33.6 Deg C | 32.7 Deg C |
| Ultra Kaze 3000 | 31.5 Deg C | 30.7 Deg C | 30.2 Deg C | 28.8 Deg C |
| Ultra Kaze 2000 | 32.3 Deg C | 30.9 Deg C | 30.4 Deg C | 29.6 Deg C |
| Ultra Kaze 1000 | 35.6 Deg C | 34.3 Deg C | 34.5 Deg C | 33.2 Deg C |
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...

Awesome detailed review Peevs. Looks like they're a winner
Thanks Kemp I'm glad you liked it.
OOOOOOoooooooo
nice review, well done.
if i get a much bigger case for me next build, i'll consider these fans instead of the thinner S-Flex.

Very sweet fans, great review Matt as usual!!! Looks like I know which fans I'll be using for my next build. 
I bet those Ultra 3000's in push/pull around a triple 120mm rad would be amazing.

@ FragTek: Yeah those Ultra 3000 would work perfectly in a push/pull config. Just make sure you run them at 7v though aight
