White noise for babies

I noticed at bed time my 2 month old likes noise but not your day time noise. I had a fan going last night it would cut on for 20 min then off for 15 min. My kid literally woke every time the noise stopped it was cute and funny but I was sleepy. So instead played a rainy day white off my phone. Now I’m looking for a good white noise machine for baby. Any suggestions? Any of you ladies use white noise? ( baby was not hot room was at 70 degrees)
