[SOLVED] Case fan wire slightly cut. What do I do?

[Pete NOR]

As the pic shows, I slightly cut the wire of my case fan. It's a 120mm 3-pin fan and only one of the three wires is exposed. A tiny bit of the metal is separated from the wire, along with some insulation.

1. I assume I should do something about it, even though it's such a minor damage/exposure?
2. Should I buy some electrical tape and cover it up?
3. Is there any risk involved in not replacing the wire or getting a new fan?

Any help is appreciated (as long as you know what you're talking about)!

1. yes.
2. Rather tape it than replacing wire or fan.
