I bought pads as well but the original ones didn’t break. I wanted to replace them with my new one, however i found the new one is more stiff while the original is soft that components can sink into it. I didn’t know that it’s a thing. So i kept the original. (If anybody is interested there were 0.5mm and 1mm pads on the cooler.)
I don’t recommend GL.inet routers. I have the Marble and it is slower than my ISPs router. It has a thing called network hardware acceleration, and it breaks my home server. Services just stop working well with it. So I keep it turned off. When I reported the issue they said it is working for them and came up with a completely hypotical setup…
With AdGuard enabled it frequently froze and I had to reboot it. For some reason even without AdGuard name resolution is noticeably slower. Doesn’t matter if I use my ISP’s DNS or not.
Also, DynDNS doesn’t support custom names, so I installed an alternative service for mywire.org.
Overally, this box came with drawbacks, but no doubt about it is hackable in the good way.
I would like to try openwrt’s own router, next time.
