Okay. that article makes perfect sense.

However if you had a silver base mounted onto a copper heatsink, you'd also find that this didn't conduct as well as an all silver heatsink (assuming you're rich enough to afford one!!).

However I bet it would conduct better than an all copper one. Just as a copper/ aluminium heatsink will work better than an all aluminium one.

Manufacturers mix the metals for reasons of economy.

My heatsinks are just made out of bits of scrap brass and copper, and they work much better than the majority of overpriced and over engineered commercial offerings.

Nice work there! Grin

Those brass pots look really cool! I've seen something very similar being used on a Voodoo2 before, with the 3-way outlets on each pot!

Let paulpsomiadis have a look at these! He's seriously into his modding as well! Grin

He might take up your idea for his Gainward Dragon 3000 SLI pair! If he can part with his beloved green heatsinks! Wink

They'll never run as cool as my voodoo's though! Tongue

BTW, the heatsinks are actually copper- just the pipes which are made from brass.

Here is an early pic of the then unpainted heatsinks-

They were made from scrap pieces of 22mm copper pipe.

The bases were bits of tube cut down the middle with tin snips and flattened out and linished smooth. The whole lot was soft soldered together with a small blowlamp.

Took about an evening to make all six heatsinks, and only cost a few pence in materials.

The reason I watercooled my Voodoo 2 cards was because of crashing. This was happening in a very modest Pentium II system, so heaven knows how it would have got on in a Athlon based system.

When really pushed, I found the SLI arrangement didn't lend itself well to free flow of air- cards are much too close together.

Plus I hate the racket lots of fans make!!

At the same time, I decided to upgrade my computer, this involved the purchase of a Athlon 2600XP, 1GB RAM, MSI Nforce 2 mobo and a Geforce 4 4600 TI (freebie).

I figured this system would be noisy using conventional air cooling, so investigated watercooling.

The systems featured on the market are over engineered and cost a small fortune, so I built my own.

Took a bit of thinking out and a bit of plunder in the scrapyard for a S/H Ford Transit heater matrix.

My System runs at between 10-15 degrees C above ambient, so most of the time that translates to about 35-40 degrees C (read using mobo/socket temperature sensors), equivalent air cooling seems to be about 10 degrees hotter.

My Voodoo cards no longer crash or lock up, and the Geforce 4 Ti card that was given to me due to it crashing my friends system (probably overheating looking at the woefully inadequate heatsink), runs as sweet as an angels kiss.

Next project- watercooled Athlon based glide box with Voodoo 5500.
