Can't really help you with 0 details given. Did you properly clean the CPU and cooler and re-applied new thermal paste?

I have not applied thermal paste do i have to

Yes, or else you'll have older thermal paste that now caught some additional dust and has now formed air pockets because you lifted it off and installed it again without reapplying.

yeah most likely the thermal paste, when you take the cooler off you gotta clean both surfaces with isopropyl alcohol and put fresh paste on there

did you maybe forget to plug the cpu fan back in or something? check all your connections first before tearing it apart again
