Hello

I am building a PC..and i'm a bit rusty last time I built one was a while ago.
My AMD CPU has a stock cooler which appears to have thermal paste on the bottom of it.
Then why does the manual say I need to apply thermal paste too?

Cheers
 
The manual for what? There's no standard for whether coolers come with pre-applied thermal paste or not so if it's something like the motherboard manual it can be ignored.

Thermal paste is designed to fill in microscopic gaps where metal on metal contact isn't possible so you generally want tiny amounts. It'd be odd if the CPU instructions say apply some more to a cooler that has some pre-applied.
 
I've built two machines in recent months, one with a Ryzen 7 and one with a Ryzen 9. Both had the stock cooler and the thin line of paste on the cooler is plenty adequate.
Just make sure the processor is well seated before adding the cooler. I speak from experience; one wasn't quite all the way home and system wouldn't boot.
Good luck, they're great processors.
 
My Ryzen fan had paste on it, well a pad. It will work fine without adding any but if you want beter cooling remove the factory supplied stuff and then use some TP.
