my laptop shuts down when the fan is running at full speed

petergagne2003 · Apr 9, 2018

my sony vaio laptop had an overheating problem that i fixed by taking out 2 of the fan cables to let it run at full speed, but now when i have a game or to many mozilla firefox tabs open it shuts down like someone unplugged it with no battery in.

temp never goes over 50C when it shuts down

I have tried everything but ask the internet

update : by plugging in 1 of the wires back in it runs at full speed and has a fan speed reading, this fixed it

you took out 2 of the fan cables? would not that disable the fan which will cause more heat in CPU? I advice you to put the back the cable and undo what you have done.

no i took out the yellow and orange wires that regulate the fan speed and left the black and red power wires
this makes the fan run at full speed all the time

You put back the wires and enable Active Cooling from Power settings instead of Passive cooling this keeps the fan speed constant and on all the time of running

Did you try to use 3rd party software like MSI after Burner to control the fan? and try to plug the wires and check if it still turns off...
