HWMonitor is also a good tool for monitoring notebook PCs, which often run hotter than desktops, thanks to their compact enclosures and less vigorous ventilation ( see Figure 2). Although manufacturers often cite acceptable temperature ranges that climb as high as 80° C (176° F), in practice you don't want to see values above 60° C (140° F), with a distinct preference for 'cooler is better.' As Figure 1 shows for the test system, readings in the range of mid-20° C range (mid-70° F) to high 40° C (under 120° F) are signs of a healthy, well-ventilated desktop PC. (For an example of such readings, see the CPUID home page for HWMonitor.)Įxperience teaches savvy PC owners what kinds of temperature readings are 'healthy' for their systems. The SeaSonic S12 500W power supply in the test system lacks such capability, however. Systems with monitored power supplies (such as the Gigabyte ODIN or the Tagan JK family) can also report into HWMonitor with voltage, current, and output power and temperature readings.This test system also uses a pair of SATA drives in a RAID 1 configuration, but the Intel Matrix Storage Manager doesn't report on their temperatures, nor does it provide direct support for SMART reporting. For systems with SMART hard disk support (must be enabled in the BIOS to be reported), the system reports on all standard SMART disk temperatures.For graphics adapters with built-in temperature sensors, including the NVIDIA 8600 GTS in the test system, GPU core temperatures are reported.Each of the cores in the QX9650 in this test machine reports an individual core temperature, as shown in Figure 1. The program works with most Intel, AMD, VIA, and many types of ARM processors. For CPUs that include built-in temperature sensors, HWMonitor can report those values.The IT8718 can handle up to five fans, but Gigabyte reports on only four fan headers on the GA-P35T-DQ6, having omitted the Northbridge fan the machine monitored here doesn't use the SYS_FAN2 and PWR_FAN headers, and thus reports only SYS_FAN1 and CPU_FAN values.
