The diagram shows the influence of Kaze Maru fan-speed on the cooling-performance of Orochi. Room temperature was 19°C, CPU was stressed using prime95 multi (small FFTs).
The test was performed outside of a PC Case in constant environment without airflow.
Additional Test in semi-passive mode to show more "real" conditions:
Case: Fenriswolf 2x 1200 Slipstream@5V (front/rear)
CPU: Phenom 2 X4 940BE @3 GHz/1,25 V
GPU: ATi HD3850
Prime 95 multithread Small FFTs
Temp: 54°C
