Recommendations for a good iBook laptop-style cooler?

[LilsDada]

Can anyone recommend a good iBook laptop-style cooler please? I've found that my iBook G3 is running very hot, I just yesterday installed a 120GB mSATA (via IDE adaptor) and it seems like it's running noticeably hotter than before. Had a look on the usual shopping sites and trawled the net for a suitable cooler but coming up empty for a iBook-compatible one. At the moment I have a metal kitchen plate cooler elevating it a few cms but would prefer something more active, despite any fan noise etc. It would be very useful to have USB passthrough that works too, expecting a lot aren't I! haha
Thanks
