I don't have any suggestions, but I just wanted to say that it's really cool that you're trying to save things from becoming waste. If you manage to fix it, it's win-win.

As long as the heat pipes don't leak it should still work.

Fix it? Be a lot cooler if you did.

If the heat plate is damaged or any of those heat pipes are pinched / cracked, then you're SOL. What a lot of people don't realise is there's liquid in those pipes that evaporates on the heat plate, condenses in the cooler, and then runs back to evaporate again.

just bend the rest of your pc until the cooler fits, easy

Put it on the hood of your car

You should ask Noctua what they think, they have splendid customer support.

I would keep it as an involuntary art piece.

It's possible, and if you do it right there shouldn't be too much structural damage that would affect conductivity. It's a lot of work though.

As long as the plate is even and clean, mounting is not bent, you should be fine.

If the mounting plate is not OK, be careful - - you could damage the mobo and cpu.

Unless you can't seat it flush against the CPU, I don't even see a problem. It's a metal heatsink. The piping being bent shouldn't affect its ability to transfer heat and the fins look fine. 🤷‍♂️

I see two ways forward: either you're risk averse and assume internal damages that will highly influence heat transfer or you trust in the automatic protection mechanisms or your CPU.

Personally I'd toss it but I'm old and I've burned more than one CPU back in the days with faulty or wrongly installed coolers.

I don't think that the risk is high nowadays but I'm (literally) burned in that regard.

I'm not even sure it would survive bending back so perhaps try that first and if it breaks completely you don't even have a decision on your hand :)

I once customized a heat pipe for a tiny case. You can bend heat pipes around and they'll still work as long as you don't get a kink (pipe bent such that it flattens).
