Don't worry about it.
The stock fans should do fine.
Are you having a heat problem now?
Or, are you planning on a new build?
Either way, it is not disastrous if things heat up a bit. A cpu or gpu will throttle down to protect itself if things get dangerously hot.
Just keep the case and parts clear of dust.
its a new build and thank you i'm not so worried now this helps to finalize my build
