With 132, every logical CPU core gets its own column. The hot mode makes the percentages flicker with each keystroke on the server. You will see:
systat 132 hot
If your terminal isn’t 132 columns wide, it may wrap. Resize or force it: systat 132 hot

systat hot
Once running:
The SYSTAT 132 motherboard contains a thermistor (thermal resistor) located near the voltage regulator module. When the ambient internal temperature exceeds 85° Celsius (185° Fahrenheit) , the system logic interprets this as "Hot" and does one of two things: With 132 , every logical CPU core gets its own column
If your SYSTAT 132 remains "hot" after cleaning and voltage checks, the internal thermal paste between the CPU and heat sink has likely dried out (cracking). While a technically skilled user can reapply Arctic Silver thermal paste, SYSTAT recommends board-level replacement for units over 10 years old. Refurbished power boards for the 132 series are available for roughly $400–$600. If your terminal isn’t 132 columns wide, it may wrap
When a technician says the unit is "SYSTAT 132 hot," they are usually referring to one of three specific triggers:
Rarely, a firmware bug causes the processor to run at 100% duty cycle indefinitely. Check SYSTAT’s knowledge base for version 4.1.2, which fixed a "thermal idle loop" bug.
