I think i did something wrong? I completed all the steps but my fan (which is brand new) keeps making this scary loud wizzy noise instead of a hum and did i not tightem the screws enough or they to tight?? Please help!

Please ensure the fan metal case is not bent and ensure the fan is properly mounted. If this doesn’t solve your problem, your new fan is defective.

I can’t remove the laptop fan screw because they are too small, what are other alternative if you don’t have one of those small screwdriver?

my CQ58 fan was just stuttering, not even a complete revolution. took laptop apart, barely any dust so replaced fan. Still nothing , just the same as before.

it did power up for a minute just once but then when i had put it all back together, with every screw back in, it went back to stuttering again.

3 times i’ve had this thing apart and no one seems to have had this issue on the net.

any suggestions before it’s thrown the length of the garden?
