I don't see that the two are at all similar. Not even close.
If you could find an end user that is big into CPU/ PC cooling like Thermaltake, Arctic, Zalman, Asus, Coolermaster, etc. or a retailer big into cutom PCs like overclockers.co.uk or ncix.com there's no telling how much you could get for it.
I'd say it's safely worth 10k, but you could get more for it I'm sure.
Great domain.
