Solved! laptop faulty cpu fan?

[entice3]

hey,

I recently sent my laptop back for a hard drive replacement as the hard drive had failed, the hard drive was replaced, the fans were cleaned, heatsinks were cleaned and new high end paste was added

when I received my laptop back there was a loud rattling noise present from within the laptop which frequently happens

With the laptop stationary it can be quiet. Picking it up and gently shaking it, it will also be quiet

with the laptop stationary and the rattling noise begins to happen, picking it up and gently shaking it causes the rattling to become louder, harsher and sound very bad

We opened the laptop and noticed a few scratch defects on the cpu fan which is located at the same place the rattling happens as if something has been catching on the fan and it has become damaged

There is a strong correlation that the rattling noise happens upon intensive tasks and when the fans can be faintly heard being active

resorting to closing all apps and making the laptop idle, the fans go quieter and eventually the rattle goes away

We tried booting the laptop without the dvd drive in but the rattle still happened and we don't think it's the hard drive

Any thoughts?

If you shake it a lot while it is doing work then you will end up trashing the hard drive. Be careful.

Thoughts.... contact the place that repaired it and get them to fix whatever they damaged. On them of course.

it is possible something has become damaged with the fan along the way

I bought the laptop to be used as a semi-performance travel laptop so obviously didn't go all out on a high spec machine

it's been well looked after and has served me well and am happy with it in terms of performance in general

I'm currently talking to the support team as to whether it should be sent back again or if they could send me out a replacement cpu fan which we can replace and test to see if it fixes the problem

the rattling is quite loud when stationary and upon moving the laptop it becomes even louder and sounds as if something is being destroyed/degrading within the laptop because it sounds so bad

we're almost certain it's the cpu fan at fault but really am waiting for a replacement from the support team to confirm
