An Intel Core i5-4430 processor with a thermal design power (TDP) of 85 W is the basis for our ITX cooler testing. These devices are required for small form factor PCs (SFF). The processor does not fully utilize the 85 W envelope and hence is close to the 65 W category, which enables us to also include very compact ITX cooling solutions - these usually aren't designed for high performance, high power processors. The test environment is a Xilence Torino case, equipped with a 120-mm fan in the front section and an 80-mm device in the rear part.
The system runs at maximum CPU load running Prime95 for a period of 70 minutes. We track all parameters using Aida64. The last ten minutes of the test run are actually used for collecting test results: We calculate the arithmetic mean of the CPU core temperature over the duration of these ten minutes and present the results showing temperature Delta K as well as based on a theoretical room temperature of 20°C. If, based on this room temperature, the core temperature exceeds 70°C, the product failed the test and we abort the process, as the cooling solution cannot handle the thermal load. We keep track on the environment temperature during the test run with a Voltcraft PL-120-T2 thermometer. We also measure noise levels with the side panel opened, at a distance of 30 cm from the top of the CPU cooler. This results in noise levels that are higher than what you’ll experience in everyday operation, but it ensures that we actually track cooler noise and not some acoustic interference. The acuostic measurements are performed with a Voltcraft VL-100, positioned in a right angle towards the cooler and motherboard. Please look at our cooler testing introduction article for more details on our reference test system.
