Netgear C7000v2 Cable Wifi Router Rebooting Itself SOLVED

I purchased the Netgear C7000v2 Cable Wifi Router in early 2019 and the unit would reboot itself randomly for months. I tried everything you could possibly think of from changing every setting to connections to the wall plugs to the firmware which you can't update or rollback because the ISP is the only one who can push firmware updates to these modems. I finally contacted Netgear and saving a lot of time I told them I'm highly technical and was able to cut through the red tape. Under warranty, they agreed to swap out the router. This took about a week. A new router arrives and I shipped the old one back to them. Setup the new router and I'll be damned if, within a short period of time, the same thing was happening again. This thing is rebooting itself and does so for a week. I've always felt these devices ran a little hot and thought to myself I wonder if I add a fan would this fix the issue. I ordered a fan on amazon, and it's one that plugs into your wall outlet, mounted it on side of the wifi router unit with cable ties and I haven't had one issue for the past week. The router is cool to the touch, hasn't rebooted itself once, bandwidth speeds are perfect AND as crazy at this sounds the interface loads extremely fast on browsers and the genie phone app connects immediately when launched. I've never seen the router pages load so quickly nor the app be so responsive. 

Have I discovered the problem? You tell me!
