Testing and results

We followed our standard case testing methodology, as detailed in our previous heatsink and case testing article, and fitted the usual set of hardware into the case, doing our best to hide and tidy cables to ensure as few airflow restrictions as possible. Luckily this wasn't difficult in the GS1000 Plus. Here's a reminder of the hardware we use.
  • CPU: Lapped Intel Pentium XE 955 (dual-core, 3.46GHz)
  • Graphics Card: Sapphire Radeon HD 3850 Ultimate passive cooled
  • Motherboard: MSI P6N SLI Platinum
  • RAM: 2 x 512MB Corsair XMS2-667
  • Hard Drive: 1 x 250GB Western Digital WD2500 7,200RPM
  • Heatsink: Asus Silent Square Pro
  • Power Supply: Xilence XP700 700W PSU

While this isn't representative of current high-end hardware, the equipment we use is specifically selected to kick out the maximum amount of heat inside the case. With a passively cooled graphics card and 130W TDP processor at its core to really heat things up and push the case's ability to cope with toasty components to the limit.

In our experience, our CPU stress test is a good way of indicating a case's ability to exhaust hot air and the GPU stress test is a better indicator of a case's intake ability. This is because the GPU is generally further from the exhaust fan and so its operating temperatures rely more on case airflow than exhaust.

Following feedback from the bit-tech community, we've changed the way we display case thermal performance. We've removed ambient and case temperatures from our graphs and just left the more important values of GPU and CPU Delta T – the differences between the ambient temperatures and the component's temperature. We feel this provides a much clearer representation of a case's cooling ability where it counts, as well as producing results that are much easier to digest.
