Lenovo Yoga 3 1470 Fan Grinding Noise

2016-03-30, 15:51 PM

To start, I have seen the thread about a high pitched noise issue with this device's fan, and I don't think my problem is the same one.


I have an ongoing issue with my Yoga 3 (full specs below), where for most of the time that the fan is spinning, it makes a loud grinding noise as if there's something stuck in the fan or the blade is off balance.


I've only had the laptop for six months and it wasn't a problem when I bought it - it's developed since. The fan still seems to cool the laptop properly, and I've had no warnings from the device, but it's audible in quieter rooms and definitely isn't normal.


I've installed the BIOS update that was recommended for a similar fan issue, and I've used OneKey Optimiser to run the fan cleaning tool several times - nothing has changed so far.


I'm not sure what to do next. Should I attempt to open the machine and clean the fan unit with compressed air/investigate further, or should I contact someone about a repair?





Solved! See the solution

Hi aaroncawte , 


Welcome to the Community Forums. 


As what you have already described , seems that you have done what is needed fro the fan noise issue. 

Noting that the issue is mechanical in nature , please give tech support a call for the needed service . 

No need to open the chassis for further steps not to invalidate the seal / warranty and have the tech run further check.


You can however run Lenovo Solution Center for the hardware test just to check on other parts that can also be affected and likewise temperature check at the moment of the noise for baseline data. 


You may reach them at :

I had a similar issue and was able to resolve  it by unscrewing the back lid and jamming a bit of folded tape under the lower left and lower right corners of the fan's casing using a sharp tip of a flat screwdriver. This lifted the fan from whatever it was grinding against (keyboard?) by half a millimeter or so, and completely removed the grinding noise.
