Copper.

Oh dear. One more time he submits the evidence that he has no idea of thermodynamics. Not at all. All this stuff only to distinguish himself.

The assignment of a good heatsink is to dissipate the heat to the air or ohter medium. But copper leads and accumulates the heat. Aluminum is much more better for. Not to mention about the weight...

Hello Backfire,

You are right, I dont have idea of thermodynamics then it means I can't build my own heatsink? Are you trying to leave me in evidence talking about what I know or what I dont know?

Agree that copper accumulates too much heat but Heatsink comes ready to install 2 front and 2 rear fans. So I don't see problem here either. Once tested the card without fan, I noticed that heatsink absorbs too much heat and this heat needs to be dissipated via air.

Equal condition the copper heatsink should improve the performance compared aluminium heatsink. This is my point. Perhaps I am wrong, we will see...

About weight- yes, and where is the problem? Card will perform less if heatsink is heavy? No, then where is the problem?

that the card will probably be damaged if you put so much weight on the card. remember the v6ks are pretty fragile.. if you install them in a horizontal position even when using the original heatsinks they have a bit of wobbling due to the pcb's own weight.

Greetings

The card will not be damaged cause the copper heatsink's weight.

I think the forum is a bit angry because you have bought a lot of 6ks and converted them to the "childish new wave" of todays computing. Being the 6k a prototype I don't think making so much critical modifications to them will leave a good taste in the people's mouth!. But hey, 7000 3dmarks2001 that's great!

to each it's own thing

The V5k6 Gold SE and V5k6 Legend edition (run both @201 MHz max) have become answome and more rare than a common 3700A.

Interesting thing:

On my Gold SE with 3,5 ns sdrams (not cooled) I have 201 MHz max.
On my Legend edition with 6 ns sdrams (cooled) I have 201 MHz max.

- Weight -

It is not a prbolem since the weight from heatsink will rest in the screws, as there are no parts pasted directly at the card. All the parts does perfect contact. Remember 6k comes with differents holes. I used some of them to hold the card and to get perfect contact. So again, the weight will rest directly in the screws and not in the card.

So you put a lot of stress onto these points, in that case the card can break internally without even visible from outside.

that's what I mean. If you install it someday in a vertical position you should put a Support bracket at the end of the card in order to reduce the stress made to it.. If not, you could install a backplate on the back of the board just like the ones the ati 6990 boards have. I was thinking about that and maybe it'd be great idea to put on practice.

The copper heatsink is formed by two plates (sandwich), one positioned in the front of the card and the other on the rear. Both plates are joined by 4 screws torx M3 and the weight is divided between those 4 points. The most important thing is the card is not bended and It will not happen since both heatsinks fit perfect. The stress is minimal since both heatsink are not joined with adhesive thermal paste directly on the board.
I understand as dangerous design if you use adhesive thermal paste to hold a big heatsink pasted directly on top VSA-100. Here there are a lot of stress since of the weight is supported by 4 chips bga.

Sorry to just jump in here but I felt I should help explain something....

I think what there are trying to get across to you is that the weight, no matter if the heatsink is anchored by screws or thermal paste will be a big problem. Here's my take on why: You are correct that the screws will carry the weight, BUT where is that weight transferred to? The card, cause the screws attach to it. The use of a secondary stabilization back plate or extra anchor plate for the card seem a prudent choice.

So, I keep the card in perfect alignment and weight will rest between adapter and plate support.

Yeah. Place a brick under the card and make it 'answome'. I was looking at the mods with interest, but this is slowly getting ridiculous. Mods are usually being done for one of the following reasons:
1) make the cooling better, overclock to squeeze out maximum.
2) make the card silent with passive cooling
3) make the card better looking

Everything else is a waste of time. The water cooling - alright, thats the overclock theme - but this? This is just BS.

Two rear blocks: Copper sheet came in. I adjusted it for joining both heatsink. I did 3 holes in the copper sheet and 3 holes more in the base from left heatsink.

As everythng is just pure copper, the heat will just accumulate inside the "cooler", you'll need quite a good airflow to get rid of the stored energy.
