Legion Y520T-25ICZ: CPU fan error & spin up every 10 sec

2020-12-28, 11:13 AM

Over the last few days, I've started noticing the CPU fan of my Legion Y520T-25ICZ - Type 90JB - desktop PC starts kicking in every 10 to 15 seconds, which almost sounds like it's revving up. At startup, the BIOS screen also notes a CPU fan error. I've also checked to see if any software might be causing this, and it isn't. Everything is otherwise normal with my OS and other hardware. The inside of my machine is also clean and free of dust.

 

I've had this Lenovo machine about 3 years now and it's been great, plus I can't afford a new PC, therefore I'd like to get to the bottom of resolving my current issue.

 

Unfortunately, it seems the Lenovo Software Bridge diagnostic tool doesn't perform tests on fans. Full scan shows nothing, while selecting "FAN" only in the custom quick scan options presents "ModuleNotSupport" as the reply.

 

Any help or advice appreciated, especially regarding this type of Lenovo desktop.

Hello @HeathGCF,

 

Welcome to the Community Forums.

I apologize for the late reply. Kindly let me know if you are still having this issue.

 

I would recommend checking if the fan is properly connected to the motherboard and that no foreign objects like dust or hair is blocking the fans.

 

You can also look into the option of replacing the CPU fan.

 

Here is the part number: 01MN069

Hi @Jack_Lenovo1 and thanks for replying,

 

The fan itself is clean, free of dust and hair, so I suspect the unit itself has failed.

 

Is there anywhere here within the Lenovo site where I can buy a replacement, or given that I'm in Spain, an approved supplier within Europe?

 

Browsing around via Google, I did find some third-party suppliers although unit cost and shipping seemed a little steep. Always nice to have a comparison and especially if it's direct from the manufacturer. Appreciate also that I'll need repaste the heatsink connection when switching units.

 

Cheers - Heath
