Thinkpad T460s sudden fan noise



Since this morning, my 3 week old ThinkPad T460s started making some weird fan noise. 

When spinning up and also while slowing down (so not on higher speeds), there's a rattling noise coming from the laptop. Sounds a bit as if the fan is brushing against something or perhaps some trembling/interference?

Also at really slow fan activity, this is audible quite heavily.


Up until now, that noise wasn't audible at all.


Should I be calling in support (I have on-site support for this machine)? I don't assume this is normal for a new machine to happen?

Welcome to the Forums Matan


Fan is very loud when the CPU load increases.  Possible causes could be dried lubrication in the fan, worn bearings, or just a dust build up. Hence try cleaning the fan once.


Hence I would suggest you visit the nearest Lenovo service centres for hardware assistance.


Update us how it goes.

It is not normal.  If the machine is new, there may be a simple mechanical failure of the fan.  Call for support and describe the problem.  Hopefully, the on-site tech can bring a fan when he or she comes.
