hi guys, i'm italian and sorry for my english not perfect...
my problem is with the cooler this laptop have a few days a problem because is hottest.
the problem is in a gpu , when i play the temperature go to 108° C :S

i change the driver of gpu and now i have the first driver when i bouth a laptop;
i change the bios with the last driver but the problem isn't resolve;

i speak with nvidia and acer forum, the nvid did me to contact the acer and the acer did me to invitee the lapton for 40€ but i dont' want.

i find the problem is the FAN ( ventole ) can you help me please?
i can't play with never game ;
p.s. i change the termical paste.

 

What's the problem with the fan?
Does it even work?

 

it doesn't work perfect. it don't go over the 728 rpm when

i open my laptop a few days a go... i change the termical paste and cleaned the fan.

 

If you are sure that it's the fan, not something else you could look infor a replacement fan (assuming it's a hardware issue)
Does the fan make any noises or something else suggests that it's failing?
How do you know the rpm?

 

in this forum i found a program for the extensa 5635 Z with can i control the temperature ( but isn't correct) and the speed fan ... i'm a lot of experience with the desktop but with a laptop i can do little.

 

can you help me?

 

we can't have many solution?

 

Does the fan speed increase when CPU/GPU is under load?
Is CPU getting hot too?

Are you sure that the heatsink makes proper contact with GPU?
