HP ENVY Phoenix Desktop - 514 Liquid Cooler Fan not detected

[YHLIEW]

Hi,

I have a HP ENVY Phoenix Desktop - 810-493d (ENERGY STAR).

The Fan in my computer has been getting louder and having weird sounds over the past few months.

Recently, I have been receiveing a notification whenever i boot my computer.

The notification is mainly about "514 Liquid Cooler Fan not detected" and then I have to press F1 to boot.

May I know what should I do?

Thanks!

Have you opened the case and looked at the fan and the CPU_Fan  and pump motor electrical connectors?

If the fan and heat exchanger are covered with dust that can easily cause the issue you are seeing.

Hi.

Thanks for the reply!

I have tried cleaning them with a small manual air pump (Those u use for cleaing Cameras)

I have also remove and reattached both the Pump Fan and the other Fan.

However, the same screen of "514 Liquid Cooler Fan not detected" still appeared after 1 day.

That would seem to point to a failed sensor in the fan. The same happens with normal CPU fans sometimes and the solution is replacement of the fan.

Contact HP for warranty service or replacement.
