Hello everyone, just wanted to get some help, did anyone had a familiar engine noise before? Normal or needs attention?

Scenario is: i start the engine, let it warm up for approximately 30-60 seconds, now i start driving and when accelerating it makes a louder rattling noise, then when i accelerate abit more it goes away, but when accelerating steady gently it makes a rattling noise ONLY when engine is cold. Any advice would be appreciated.
