Question Need to repaste?

[balinteduard]

Hi.
I am building my pc now, and I have unmounted the cpu cooler because I can't install the RAM.
Now I need to clean and repaste the cpu or I can reinstall the cpu cooler?
Will be wrong if I will reinstall the cooler?
It was not used, or burned the paste.
Help

If the cooler or cpu hasn't got any dirt on it you should be fine without applying another round of paste.

I'd repaste it. There could be air bubbles.
