HWiNFO can read a huge range of sensors, which makes the first screen look harder than the diagnosis. You need a small set: CPU and GPU temperature, power, clock and limit reasons, plus fan and drive readings. Start in Sensors-only mode and build a layout around the fault you are testing.

Quick Answer

Launch HWiNFO from its official source, choose Sensors-only and let the table populate. Reset minimum, maximum and average columns before a repeatable game. Watch CPU package temperature and power, GPU temperature, hotspot, graphics power, clocks and fan speed. Save a log when the problem is intermittent.

Evetech's gaming PC systems give you the hardware identity needed to interpret sensors. The PC best sellers provide a wider reference without replacing the limits and guidance for your exact CPU, GPU and SSD.

Choose Sensors-Only for Diagnosis

The Summary window is useful for component identity. Sensors-only is where you follow behaviour over time. It lists Current, Minimum, Maximum and Average values for each reading.

Expand the CPU, GPU, motherboard and drive sections. Hide or collapse values unrelated to the current question. A short view reduces the chance of reading a similarly named sensor from the wrong device.

Run HWiNFO as a monitor, not as an automatic verdict. A red number can reflect a user threshold or brief maximum rather than a fault.

Read CPU Temperature With Power

Use CPU package temperature as the broad starting value, then inspect per-core readings when one looks unusual. Pair it with package power and effective clock.

A processor can run near its intended control temperature while holding strong clocks. That is different from reaching a thermal limit and reducing clock or power.

Look for thermal-throttling flags where the processor exposes them. A maximum flag tells you it happened at least once; the log shows when and for how long.

Read GPU Sensors Together

Track GPU temperature, hotspot or junction where supported, graphics power, core clock, memory use and fan speed. Hotspot is expected to sit above the general GPU reading, and the acceptable difference depends on the card design.

Performance-limit reasons can report power, voltage, utilisation or temperature. A power limit under full graphics load can be normal. A temperature reason paired with falling clocks needs a cooling check.

Do not compare a GPU hotspot limit with a CPU package target. Each sensor belongs to its own component guidance.

Check Drives and Fans

NVMe SSDs can expose one or several temperature sensors. Watch for thermal-throttling flags and sustained transfer behaviour rather than one idle value.

Motherboard fan labels may not match the physical header when a builder used a hub. Change one supported fan curve or inspect one header at a time before renaming it.

A zero fan reading can mean fan-stop mode, an unused header or a signal not passed through the hub. Confirm visually before calling it failed.

Reset and Log the Test

Click Reset Values just before the workload. Run the same game scene long enough to warm the system. Save a CSV log when a crash, clock drop or fan surge occurs after several minutes.

Record the room temperature, case panels, fan profile, BIOS and driver beside the log. HWiNFO cannot know those test conditions.

Polling too fast can add overhead or conflict with another hardware monitor. Use a sensible interval and run one primary sensor tool during diagnosis.

Interpret Normal Variation

Short boost spikes can create a high maximum while the average remains modest. Fan control can trail temperature as the heatsink stores and releases heat.

Compare sustained plateaus and events. A temperature that rises, clocks that fall and a thermal flag that changes at the same time form a stronger diagnosis than any one column.

Use Alerts Without Creating Panic

HWiNFO can expose alerts and tray values for selected sensors. Choose a small number tied to documented component limits, such as coolant pump speed or a drive warning. A generic temperature copied from another CPU can create noise rather than protection.

Test the alert while you are present and confirm the sensor label is correct. Keep motherboard firmware protections enabled; monitoring software is an observer, not a replacement for hardware shutdown control.

Share a Useful Log

When asking for support, include the workload start time, fault time and the handful of relevant columns. Crop account names and device serials. A short log covering the event is easier to interpret than an hour of every sensor the board exposes.

Keep the original CSV unchanged and work from a copy. Note units because watts, volts, megahertz and degrees can look similar in an exported table.

FAQ

Which HWiNFO view should a beginner use?

Use Summary for identity and Sensors-only for temperature, power, clock and fan behaviour during a workload.

Is HWiNFO safe beside a game?

Yes when obtained from its official source and used at a sensible polling rate. Avoid running several sensor tools together.

How do I know whether a GPU temperature is normal?

Compare the exact GPU maker's limits and review temperature with power, clock, fan speed and limit reason.

Open Sensors-only, reset the columns and log one warm game with temperature, power, clock and limit reason read as a set.
