My memory sticks have blue LED lights that pulse. I can see the glow through the venting on my case. It's distracting when I'm watching a movie in a dark room.

Is it okay if I just put black electrical tape over the LEDS? I don't know if memory gets hot. Would this cause any problems like overheating?

Thanks.
