Thinkpad P51 odd fan start sound

2017-07-17, 11:26 AM

Hi all,

 

I have a question about my Thinkpad P51 (20hh0014rt).

 

The system is pretty quiet at all, but I found that CPU fan (the right one) produce some kind of odd sound when it start to spin: I hear it like some quiet sneeze, or something like loud "Pffffff".

I attached audio example and also here is the Clyp link.

 

Phisically it looks like the fan start to spin at full speed and immediately slow down to lower speed.

 

Could some of P51 owners or may be Lenovo guys tell me if this is a normal behaviour for this system or I have a problem?

 

Thanks!

Solved! See the solution

You describe it very nicely^^.

I too am having this sound lately, although I don't remember to have had it when I first got my P51 Xeon, it only started a while ago, making me notice it.

 

Although it is written here that this is "normal" behavior, it is quite odd indeed, and just a tad annoying...
