I've had my K53Jr Asus laptop for over 4 years now and it only recently started to freeze up. I have a feeling my fan is going out, I have a 1GB GPU, but I have tried to up my fan speed, but that won't work. My temp doesn't really get above 53 and most of the time hovers around 51C. I just remember I used to be able to hear my fan more, now it isn't as much. It doesn't freeze up terribly often to where I can't use it, just after I have been on it for a while or in one place, and it usually stops after a minute or 2 and I blow some air into the vent. I have blown out the dust inside and everything but hasn't really helped. I have had it freeze and make a weird noise that seems like the HDD but it has only done that once or twice. I am wondering what to do, would it be difficult or expensive to replace my fan? Is it just a matter of time before the fan goes totally out? Or is it not just the fan? Anyone know how I can up the speed on this computer, I have tried lots of programs to try, but none of them ever worked. Any help would be appreciated.
