If you’re curious about the hardware that beats inside your system, do I have a utility for you. HWiNFO delves into every nook and cranny. From the summary (shown here) to detailed Device Manager-style trees of information -- entire forests of information -- HWiNFO can tell you everything anyone could want to know about your machine.
There’s a separate real-time monitoring panel, which tells you the current status of everything under the sun: Temperatures, speeds, usage, clocks, voltages, wattages, hard drive SMART stats, read rates, write rates, GPU load, network throughput, and on and on.
