Just an FYI, posted with no affiliation to the vendor.
2CoolTech, an online pee-cee store with various heat sinks, thermal compounds, lighting and other bling-bling is going out of business and offering their stock at 50% off.
I just blew through $50 USD for some goodies. Lots of stuff for tricking out Macs or PCs. I bought a blue cold-cathode for my G3.;)
* An amusing note; they have a dedicated Mac section, containing: A Fan.
