Testing:

In this part of testing, the Coolermaster ATCS 840 enclosure will be put through a series of temperature tests to see how high they rise during idle state and while the computer is under full load conditions. Temperatures of the processor, video card, hard drive and chipset will be monitored and collected. For idle state, the computer will simply be left untouched for thirty minutes, making sure nothing is active besides the Windows operating system, and then temperature readings will be taken. After, in order to simulate a full load, Orthos, 3DMark Vantage and HDTune will be ran simultaneously for half an hour to ensure that the hardware will still be fine in a worst conditions scenario. To gather the temperatures, the latest version of EVEREST will be used since it provides accurate readings of every important part. Cooling for the cases will consist of stock cooling that came with the cases along with an additional fan installed on the hard drive tray and the processor heatsink will be the Zalman 9700NT. The Coolermaster case will be compared to the Antec Sonata III to get an idea of where it stands amongst other cases on the market.

Testing System

Comparison Case: Antec Sonata III

Overclocked settings

  • Processor: Intel Core 2 Duo @ 4.0 GHz (471x8.5) w/ 1.4750Vcore
  • System Memory: Mushkin Redline XP2 PC2-8000 2x2GB @ 942 MHz 5-5-5-12
  • Palit ATI Radeon HD4850 @ 705MHz

 

As far as temperatures go, Coolermaster's enclosure took the top position in every single test and sometimes by a wide margin. The processor enjoyed the most significant temperature improvement, decreasing by up to a whole 11 Celsius in fully loaded overclocked settings. The chipset cooler didn't benefit nearly as much from the huge case, except under load where it cut the temperature by four degrees Celsius. The hard drives were also able to run quite a bit cooler and only had two Celsius delta between load and idle conditions. Finally, the video card did run ten degrees Celsius lower while idling, but load temperatures we're still pretty high using the card's default fan settings.

The whole tour is done, so let's conclude this.
