Really depends on the drive. The one that died and my new SSD both have specified operating temps from 0°C to 70°C Exceeding operating temps for longer periods of time will cause damage to the drive and often activates throttling.

I can route selected devices/groups/VLANs through the client. That’s how I’m using it with my phone. Phone connects to wireguard server. Wireguard server IP is in the router’s VPN client list for outbound traffic.

➡️ local access + VPN for web

I‘m using two different setups:

Phone with wireguard app:

• VPN client installed on my router
• WireGuard server Running on Router
• Phone connects to the routers wireguard server and from there my phone is routed through the VPN client for web traffic (but I’m not using OpenWRT so you have to check if this is possible for you)

Laptop with wireguard app and VPN installed as browser extension:

• WireGuard app is configured to only route traffic to my local subnets through the wireguard VPN.
• Web browser is encrypted through the VPN extension.

Really depends on what you need. For me this setup fits my bill.

But there’s also tailscale (which you can also selfhost: headscale)

Additionally you could also set up your own independent wireguard server to get more granular control for routing and firewalling. But you would need a device that’s running 24/7 (same for headscale). A raspberry pi would probably be enough for that.
