How hot does your CPU or graphics card get in a game, and are the fans keeping up? The free HWMonitor from CPUID shows live temperatures, voltages and fan speeds, and organizes detected components and their sensor values in a tree, so you can inspect CPU or GPU conditions while a workload is running.
Read the sensor values for each component
HWMonitor groups detected hardware and sensor entries in a tree-style view. Expand a component to see measurements such as temperature, voltage, power, current, fan speed, utilization, or clock speed. The exact readings vary with the PC's components and available sensors.
Each sensor can show its current reading along with minimum and maximum values recorded during the monitoring session. Those extremes add context to a live temperature or voltage reading, such as when watching a CPU during a demanding task.
Watch temperatures and fan speeds under load
Keep HWMonitor open while running a game, editing software, or another demanding workload to observe supported CPU and GPU sensors in real time. Temperature and fan readings provide a direct view of how the system responds as activity changes.
The same readings can help assess cooling after cleaning a PC or changing thermal paste: compare the observed temperatures under similar conditions.
Inspect storage, memory, and battery sensors
Monitoring extends beyond processor temperatures. HWMonitor can read thermal sensors on memory modules, battery sensors, and S.M.A.R.T. information from SSDs and hard disks. It also supports monitoring chips on motherboards and other hardware, including LPCIO chips from ITE, Winbond, and Nuvoton.
Expand the relevant hardware entry to find the readings HWMonitor detects.

What hardware readings does HWMonitor show?
It can display temperatures, voltages, power, current, fan speeds, utilization, and clock speeds, along with supported memory, storage, and battery sensor data.
What do the minimum and maximum values mean?
They show the lowest and highest readings recorded for a sensor during the monitoring session, alongside its current value.
Can HWMonitor read SSD and hard-disk health data?
It can read S.M.A.R.T. data from SSDs and hard disks.
