Intel® Cryo Cooling Technology LED Indicator Colors - Modes of Operation

• No power connection to hardware.
• A possible setup misconfiguration, or a visible physical or electrical damage.
• This may indicate the controller board is defective or USB power is disabled, or power cable is not properly connected.
• Confirm that all hardware sensors, power cables, fan, pump cable harnesses are correctly connected.
• Contact your manufacturer for support: 
  • Cooler Master*
  • EKWB*

• Unexpected error status
• Power applied and USB micro-B connection is good.
• A possible setup misconfiguration, or a visible physical or electrical damage.
• Confirm that all hardware sensors, power cables, fan, pump cable harnesses are correctly connected.
• Reinstall Intel® Cryo Cooling Technology software.
• Contact your manufacturer for support. (See links above.)

• Expected normal functional status.
• Standby mode [no sub-ambient cooling].
• Cryo Cooling Technology capabilities are disabled.
• Cryo Cooling Technology disables sub-ambient cooling.
• Cryo Cooling radiator fans, and pump to provide typical liquid cooling capability without sub-ambient cooling.

• Expected normal functional status.
• Cryo Cooling mode [regulated temperature above dew point].
• Cryo Cooling Technology capabilities are enabled.
• Cryo Cooling Technology dynamically controls sub-ambient cooling, fans, and pump to provide maximum regulated sub-ambient cooling to avoid condensation on CPU heatsink surfaces.

• Diagnostic Test.
• This Built-in Self-Test (BIST) confirms expected Cryo hardware power and sensor connection and functionality.
• Results displayed, while final temperature is expected to be less than initial temperature.
• Any results/errors are logged.
• Visit How to Run a Diagnostic Test on my Cryo Cooling Technology for more info.

• Expected normal functional status.
• Cryo Cooling Mode [Unregulated temperature may create condensation].
• Cryo Cooling Technology capabilities are enabled.
• This mode allows users to force the sub-ambient cooler to maximum power state (within device safety limits) increasing condensation risk on processor heatsink surfaces and surrounding areas. This can cause permanent system damage. See Note box below.

• Unregulated mode may cause condensation, which could result in an electrical short circuit that can cause damage to your computer or create a safety hazard.
• To minimize this risk, confirm the provided Cryo Cooler processor is securely installed to form an airtight seal between the motherboard and the cooler water block.
• Continuous monitoring is required on any system or component surface to safely and immediately remove wetness by a clean wick/dry material.
• By using unregulated mode, user acknowledges and accepts all the risks associated with operating in this mode.
