Same thing with my T-100, one bolt is rusty.

I finally got tired of my fan going out and fixed the connection. I couldn't find a connector like the white plastic one, so I just cut the wire, replaced it with some heavy wire from Radio Shack and used two connectors that fit the tabs on the fan blower. The fan works great now and I haven't noticed any heat.

Easy fix that cost about 8 bucks (wire and connectors).
