Hello, I just bought a gtx 1070..I'm not sure if i'm paranoid, but there are 2 SMALL scratches on one of the copper slots...ill post a picture... i'm not sure if those are scratches or not, but there are 2 small lines..you can't see it in the picture..but i have 2 arrows pointed to the copper pieces that are scratched.. I'm not sure if i should be concerned about this

I'm not sure what those copper slots do, because my gpu is already inserted into my pci slot...those copper slots are for something else...Nothing to worry about.  Those connectors are for SLI which you would use if you were connecting multiple GPUs together.  Minor marks on connectors on components are nothing to worry about, the ones there will have just occurred in manufacturing.  Look at the connectors on a GPU or some sticks of RAM after you've put them in a slot and taken them out a few times, they will have much more noticeable marks on them (which do nothing to impact functionality)Ah ok, and one more thing.  I used compressed can air to blast the *censored* out of my gpu fan.  Someone was telling me i damaged the bearing and probably dislocated the fan. is that true or are they trolling me?I wouldn't worry as long as the fan is still running FINE.  I'd still wonder what the point of cleaning the fan on a brand new card was though!  It's best to stop the fan from SPINNING if you clean it but people tend to way overreact over things like that.  I find that often it's the inexperienced people that go mental about how you must do x or you must never do y.  It's really pretty hard to muck up building a PC!Thank you.  I agree. I deleted most of your last post. No need to bash another site - and please watch your LANGUAGE. Thank you.
