Upgrading the stock hotend fans with the stock shroud?

I'm wanting to upgrade the stock hotend fans as they're just really loud. Not any more than anyone else's but I have my printer in my bedroom and would like to be able to hear everything better while it's running. I've seen a lot of people print new shroud and put 4010 noctua fans in but I'd rather keep the shroud as is if possible. I know I can't get noctua fans small enough for the shroud but I wondered if there were any others out there? Plug and play is expected, I'd rather leave it be than have to solder or crimp connectors. Thanks
