so i've recieved my usb keys from friedcat, they work great! but they do get very very hot.. I had a gander and it seems there's a wafer of thermal material and then a solid 3(ish)mm metal plate and that's it for cooling. I've seen pictures around with passive radiators bolted on instead, is this something i should consider?

You'll probably have them in an USB hub. Just add a USB fan to the setup. I am cooling four of them with a single fan.

There's a thread with compatible hardware and software (including fans and hubs) here.

you dont need anything geeky, just a regular household fan so the hot air doesnt just sit in one spot

True - though it can be very convenient to use USB hub to power the fan

Ya - I like how that fan keeps the whole setup self-contained. I needed an enclosed fan though … I have a very curious cat.

A small USB powered fan can help a lot. I did a small test today: https://bitcointalk.org/index.php?topic=229941.new#newintron

LOL I went a bit overboard... But I had a bunch of extra AMD stock CPU coolers, so I removed the rear metal plate, thermal pad, applied fresh thermal paste, and voila, happily mining away at 335-340mh/s in a house that's about 80 degrees ambient with --icarus-timing short option on cgminer: https://i.imgur.com/q1yIwW7l.jpg

They are totally cool to the touch though, added bonus. I just need to add fan grill to back side, and it'll be finger/cat proof too. I have 4 of them like this, just for giggles. The air blows across my keyboard, they are quiet, and my hands don't get sweaty anymore...
It was fun, I had spare parts, I know since I cannot change the clock, I cannot push them higher... I don't want to mess with the crystals, but I bet you could boost these a lot if there were variable or socket-ed crystals...

I don't understand why everyone recommends expensive USB fans when traditional fans are much more effective.

And cheap. I've got 120mm fans blowing on my rig, I paid exactly zero for these extras from my last system build. edit: were you referring to traditional household fans? If so, yes - more effective at the expense of more power.

The only shop around here that had little USB fans that stand up on a flxible shaft from the USB hub was Coles bookstore.
They seem to be intended though for people reading books a few hours a day on their Kindle or something as within days of running 24/7 both were dead...
Now I use one 120mm case-fan powered from a fan power connector inside a nearby computer.
