I recently posted a problem I had with a mesh computer that sounded really loud. I finally managed to register my computer and asked technical support what I should do. They told me that immediately the computer starts continuously tap the delete key which brought up a menu I had never seen before i.e. power. They said make sure that the q fan is enabled(it wasnt). When I enabled it immediately it went quiet, which is fine but I was wondering what exactly is going on? Does the q fan work as a backup if one of the other fans is not working properly? Every now and again you hear it (not loud) going on and off which was not the case when we first bought the computer. Could somenone shed any light on this? thank you. Spadge. :thumbsup:

Q Fan is not a separate fan, it is a program which adjusts the speed of the fan depending on the temperature of the chip. Before you enabled Q Fan your fan was probably running at max speed all the time (which was the noise you could hear). With Q Fan enabled the fan will now adjust it's speed depending on the temperature. So if the system gets hot you will probably here the fan kick in again until it cooled off. You should open the computer case and have a look at the fans to make sure they are spinning freely and not choked with dust.
The power of accurate observation is commonly called cynicism by those who haven't got it.
