What are these plugs in the gpus?

HDMI dummy plugs - it makes them think they're plugged into monitors. On Windows at least I haven't found a way to get the 470's to reliably report temp or keep fan speed without them. Nvidia cards work fine.

Laser is not mine of course it's an industrial machine. I've seen that study about grill patterns and the one I've chosen is a trade off between performance and cut costs. I would prefer wire grills but I haven't found one for that fan size at reasonable cost, yet I want to have something in front of them.

heheh, my fan's are WAY more dangerous, and I don't bother putting anything in front of them (aluminum blades)... If you don't know to not put your finger near them, then you can make that mistake 9 more times. Wink

I don't know the exact size of the fans you're using, but there are universal grills like this one:

Notice that instead of screw holes they have channels, so they can fit basically any size fine that matches their dimensions. I've seen these all over, and it's the same thing even available for my fan (at 254mm).
