Test System and Benchmark Results of the GamerStorm Captain 240

My office is climate controlled. I keep the temperature at 20°C. Upon initial start up the PC was allowed to sit for 5 minutes to let the system temperature stabilize.

All case fans were running at 100% unless otherwise specified. The fans on the radiators were manually set to 1500 RPM. Intel integrated video is utilized to eliminate additional ambient heat source from discrete graphics cards. Temperatures are averaged (last minute) from individual core temperature results monitored by AIDA64 after 15 minutes. Results marked “0″ means thermal limit was reached and the CPU was throttled and thus the results were discarded. Stock settings have all power saving features enabled in the motherboard with Vcore set static to 1.1V and set to “Balanced” in the OS. Overclocked settings have Vcore voltage manually set to 1.25V at 4.5GHz with EIST disabled. All tests were taken at least three times to get the final result.

Performance Summary:

The DeepCool GamerStorm Captain 240 plants itself firmly in the middle of the pack at stock speeds however; there is only 4.3° C separation between the coolers. Overclocked speeds show a different story. The Captain 240, while it did not throttle, averaged 68.3° C with some of the core temperatures reaching up into the 70° range. At 1500 RPM, the DeepCool fans were nearly silent. The pump with spins at a constant RPM was louder than the fans. With this configuration, the Captain 240 is not very overclocking friendly.

I looked over the fan specification and noticed that the specifications for airflow and pressure were listed at max RPM. I thought the fans may be hurting performance. I swapped the stock Deep Cool fans out with a pair of Enermax Twister Storm fans. Again, the fans were statically set at 1500 RPM.

Specifications of the Twister Storm Fans are listed below.

Captain 240

The Twister Storm fans help drop the temperature another 4.2° C at overclocked speeds. At 1500 RPM, the Twister Storm fans generate slightly more noise than the DeepCool fans at the same RPM. While not a game changer, it shows the pump and radiator combination are capable of better results.
