Hello guys,

I need a quick advise. My wife's laptop: Dell Inspiron N5110 has been behaving weird lately. You turn on the laptop and after 10 mins or so, starts what I describe as a very loud something-is-going-to-break kind of noise. The noise doesn't stop after 5 mins or so and then I turned off the laptop. Reaching the fan means fully disassembly. Which I did: I replaced the thermal pads, thermal paste. There were no dust bunnies or fluffy balls. Assembled again and I turned on, 10 mins later the same rattling noise. HDD was replaced with SSD 2 years ago, no other moving parts apart from the fan. Laptop is, I don't know 5 years old or so? You know women, they tend to use laptops on the bed, so it sucks up all kind of debris :D. Anyhow, is it the fan? I checked on Ebay and there are these super cheap Chinese knock offs:

and original ones, 3 times more expensive :) :

Should I go for the cheapest thing this time? Thanks for the advise in advance.

I wouldn't waste my time on chinese knockoffs if I were you, especially when you can get genuine parts, there's no knowing if the same might happen with the cheap one, the genuine seem to be a bit more sturdy than the cheap one.

Sounds like a fan bearing to me, and it is common enough with laptop fans. I've had mixed luck with replacing fans with a non-OEM alternative, sometimes that extra cost is worth it if you don't have to go back in there within the next few months to a year because the cheap fan did in that time what took the OEM fan 5-years.

Though if you can verify the OEM fan specs and MFG, you might be able to buy the same fan under a different vendor for a healthy savings. In the end, you get what you pay for, especially if you invest the time to research.
