I have never had a household router that had a fan in it.
Fanless mini pcs do exists they are rarer and usually more expensive and weaker.
The rebooting problem comes from micro interruption in the power grid. Yes you can add a UPS, but then these will become the main reason why the internet is down (I have a whole stack of APC branded UPS with failed batteries)
Newer WiFi 6 routers tend to have fans cause they get fairly warm but I’ve had a ups on mine for literally years and had to replace the battery in it once but before I got one even I still never had that problem we haven’t had a power outage in like a year or 2 now and I maybe happens once a year if it does so I don’t see your problem and I have it set to auto turn back on when it gets ac power so it’s a non issue
