Is my graphics card fine?

So basically I've been wondering ever since I installed it a few days ago. And I mean fine as in, not faulty, or going to fault soon, not quality of the card model. So the first thing had me worried, was a touched the circuit board when installing it by accident, I didn't feel any static, or hear any I don't think, but my finger was a little sticky pulling it off, probably as I was nervous and sweating installing it. But people have said, as long as it's working and stays cool, nothing happened. Next thing I wanna tell is temperatures. GPU Z tells me that generally during gaming, on high end new games, it reaches about 65 degrees, and at most the only game that's gone higher is Battlefield 4 with 75 degrees. Are these fine? It seems like a lot, and when they do reach those temperatures the side panel of my case is pretty damn warm, even though it's plastic and transparent and rather thing with grills for fans to be installed. I once touched the plastic safe part of the card when it was in it's full swing, and it was almost, if not too hot to touch. Is it being fried or are cards supposed to and are capable of handling that? Last thing, almost. The fans. It has 3 fans as it's the Windforce x3 Gigabyte GTX 770, also has a blower on the side and the back. I think it has one on the back anyway. Anyway, the one on the side blows out the air which is hot when gaming, and cool when not, and I can actually feel it through the fan grills on my side panel. Recently though, it's been harder to feel it through the side panel, it sort of feels less powerful. I'm wondering if it's failing or something? I usually check when the PC starts up, as the blowers are in max until the logon screen for Windows. And it's been a little harder to feel then. However, when I play games that make the air hot, I can feel that with my hands a few inches away from the case? I dunno. I can vaguely feel it as I'm typing this now, and it just feels cool but very light. I'm sure it used to be more powerful. Also, one of my 3 fans on the graphics card is right about my wireless card, literally around 10-20mm. The wireless card is still working as it should, but I'm wondering if this can cause damage to either of the cards? There is literally no where else to put the wireless card, except if I had a PCI version, but then I wouldn't have the option to SLI if I wanted to so I got the PCI-E small connector version. Thanks.
