The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this. These results are taken with the system built inside the Bitfenix Colossus which offers great airflow.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test.
The GT430 is a cool running card, peaking around 60c when gaming. Furmark pushes the card to 67c which shows in theory how hot the card could get.
Return to ambient is a feature we have recently added to our reviews … we measure the time it takes for a solution to return to idle temperatures, immediately after full load. The faster the time, the better the cooler – for example a Noctua NH D14 cooler will return an Intel processor to idle temperatures much faster than a reference cooler. This is a good indication of how quickly a heatsink can dissipate heat.
One of the inherent issues with a single slot cooler is that the return to idle state can be slower. After 30 minutes of Furmark full load, it takes a full 24 seconds for the cooler to return to the starting point.
