I'm not sure if this is done in Europe, but in the US (canada as well?) there's a "Traveling computer show" that most folks who have an e-business selling computers or computer parts attend and buy booths at. It's year-round, and there's usually one show a month here in Orlando (redrumloa and a few others probably know about 'em - Marketpro shows). Anyway, it's a good place to pick up cheap computer parts (I grabbed three 9 gig 7200RPM SCSI UW drives to throw into my video editing box for a paltry $15 each!).
ANYway, the point being is that I recall one vendor who had a few heatsinks set up on display, hooked to a power supply, but with no CPU underneath.
On the underside of each heatsink
frost had formed, and yes, Virginia, if you stuck your finger to it and held it there your fingertip would freeze onto the HS!
They were, IIRC, "golden orb" fan/hs combos.
Anyway, there was a point to this...ah well
