Anyone know where I can buy heat pipes in the UK that I can solder / paste onto a CPU HS/F that I have mounted on a graphics card?

Never seen em for sale separately.

Have a look on eBay, perhaps you might find some secondhard or just cheap CPU heatsinks, which you can mod.

Probably cheaper just to but some VGA cooler from Artic Cooler etc

Or use a bigger heatsink. I used to run a GeForce 2 with a 1GHz Celeron Fan (mind you, could put anything in the first 2 PCI slots!!:) )

Used to run nice and cool though ;)

heat pipes are probably nothing more than 1/4" copper pipe. ive got a huge coil of the stuff on hand, but i need it.

try looking in a home hardware store or plumbing store. if you can find some copper pipe that is fairly flexible, you can probably stand to just cut it to length and go from there.

I was under the impression that heatpipes were made so that they lose density along one direction, thus forcing heat energy into the lowest density side. I could be thinking of something else however? Please correct me if i'm wrong.

Actually heatpipes are filled with a fluid. They work using evaporation and condensation. Im not sure what the internal fluid is.

Is that heatpipes? I thought that was something else. Maybe what i'm blabbing about is something completely different, if you're big on your cooling then straighten this mess out please...

Well I wouldn't say that I am cooling expert at all, but I have seen heatpipes used in other applications. Wikipedia to the rescue! :D

A typical heat pipe consists of sealed hollow tube made of a thermoconductive metal such as copper or aluminium. The pipe contains a relatively small quantity of a "working fluid" or coolant (such as water, ethanol or mercury) with the remainder of the pipe being filled with vapour phase of the working fluid, all other gases being excluded.

I remembered talking about them many moons ago in my Thermodynamics class..

Hope this helps clear things up.
