my rad took a small hit
Is this an issue? I haven't tested it yet.
If it's not leaking you are fine
Yes, there might be some physical damage.
I have uploaded the image and highlighted the sole physical damage in red.
Any idea someone?
You can try it without connecting it to the PC by using alternative methods or settings.
when using a 12v system, does the pump require a 12v battery or an ac adapter?
