[rgd1101]

it is failing or not install correctly?

It's a new heatsink and yes it it's installed properly and if it's failing it always happed but it only happen when I power on my computer like 5-6 hours later also it happens rarely and when I tap on fan it stop making noise.

sound like issue with the fan. return/replace it

Verify is not hitting any cable, not that expensive to replace. I know u say u installed it correct but one of the screws loose will do it and a common mistake.
