Hi there,

I have a sony VAIO VPCCW1S1E laptop and recently I have had some issues with my fan and cooling. My fan was incredibly noisy so I decided to replace it. I found the same model of the fan online and replaced it myself. It turns out part of the reason the fan was so noisy is that two of the blades were missing. The new fan cutout a lot of the noise, but since I've replaced the fan my laptop has been overheating and shutting down. Under heavy load my laptop's CPU can reach up to a maximum of 100c which is then when I believe it shuts down. I have cleaned it as much as possible, using compressed air to get rid of most of the dust. I have even gone so far to replace some of the thermal paste and put some thermal tape in to try and cool down my processor. Nothings worked and I might have made it worse. Can anyone help me out?

Thanks.

It appears to be the same fan. It has the same model number and looks exactly the same. I don't see how the old fan would not cause it to overheat still. Personally I think I did something when I replaced the fan and now I've made it worse by trying to mess with the thermal paste/tape. Would I need thermal tape on the gpu or can I leave it off?

Oh and the fan is still spinning at 4400 RPM which seems quite high.

Thanks.

i have very similar issue with my Intel(R) Core(TM) i7-4702MQ CPU @ 2.20GHz

i had a very noisy fan so i did cleaned my fan and got rid of dust but after dusting-off it is making less noise but getting shutdown once i start playing game or stress CPU with any other app. before cleaning it was heating up but wasn't shutting down
