please put all crews back in the right place and wear esd wrist strap.
take the radiators off use tim thermal compound cleaner then dissasemble the fan and take out the dast particals.then blow the radiator out with electric solvent cleaner so nothing gonna remain between the plates.then assemble the fan back and apply new thermal compound just on those parts where was.leave the silicon pads.if they are broken or old you have to replace them.
usually the latest hp laptops having problem with bearing they just dry out i use wd40.you need just one drop in the right place.
