HELP?! Is my block faulty?

[Tyman98]

I just assembled my first watercooling kit. I got it all bled and ready out of the system and then i looked at my cpu block... One aide of the copper plate seems to have. Somthing that looks either like a crack or a lump that is bigger. Take a look.

If you did a leak test and everything is ok, then peel that sticker off and install it. Doesn't look like a problem to me.

Looks fine to me as well.
