another 6k mod? time for something different

And another V56k that is losing it's original state :(

Btw., a passive cooling solution mostly comes with a high weight, which is not very good when looking at a card as long as the V56k. It even bends with default equipped fans ::)

I think two modded V56k with waterblocks are more than enough, any more cooling solutions don't help anyone.

Yes, time for something different...

The main idea is build a passive cooling based in copper material with agressive memory timings running at default speed with an elegant design.

ps. Yes, a passive cooler implies a heavy block but will try to do something different.

Copper is very heavy, you should go for aluminum. It is very light and the cooling should be enough after all.

Hello,

Your reactions?

I don't see any big benefit in it. A custom milled passive cooler with aluminum should be enough to cool the card at default clock speeds.

Have a look at this:

feinripp is running the card without fans because it is running cool enough.

Your teaser videos don't tell that much so the whole community can't give any "reactions" at all and help you with advice.

What further reactions do you want if you only reply with "You will see..."?

I just want to say copper dissipate more heat from chip than aluminium!
We will see in the futur the benefit...
I don't speak about default frequency.

If there would be enough heat that needs to be dissipated, yes. But we have a card that only consumes about 60 watt and there isn't one big heat source that would make benefit of copper. Just keep that in mind.

You only need to look at reviews between Zalman VF700 ALCU vs VF700 CU. The difference is from 2°C to 5°C at max on cards that consume more power than a Voodoo 5 6000 and have only one big heat source.

You did write default speed and not overclocked! And even with overclocking the temperatures won't rise that much since you don't make any use of voltage modding.

But ok, make the cooler with pure copper. You will see the same effect as with the test of the first watercooling  ::)

At default speed, I will can compare with a common V5 6000 (6ns).
I keep in mind your reaction and I let you know when it's ready...

I don't see the point of this as you already have paid someone else to make you two waterblocks. Sounds like a case of more money than common sense.

I am not a waterblocks technician. The unique way is to pay someone who can build it for me.
This time with this project I had taken my time to build good heatsink.

You're making a heatsink when you already have two very nice waterblocks. I don't see what you're hoping to gain here

I used aluminium heatsinks who touch only VSA-100 chips on my Gold SE and now I want to try copper heatsinks who touch 4 GPUs and Sdrams on this other card to see the new max frequency.
I hope it will be better...

I present you The Voodoo5 6000 Silver Edition with 4ns tsop sdrams...

So a fan cooled solution after all? Good work so far, you could replace this cooler with the one on your 204 MHz card.

Yes.
what 204 MHz card?

Sorry, made a typo, I meant your Gold Second Edition with 201MHz (with those big aluminum heatsinks).

This time I will put these copper heatsinks on this Silver card with 4 ns sdrams.

After work, here is the copper heatsink without fans:

Need to put on the front of the V5 6000 card...

Not more than 2 kg.

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?

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 :)

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.

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

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

It's cool to mod a couple, but then it gets old after a while seeing the same mod over and over which produce identical scores

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.

The problem is, that the card is only holded by the front panel and what goes to the connector (if mounted horizontally in a case). 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. 

When I use my 6k across the any of my adapters I always use support below the card. 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.

Rear heatsink:

I did 3 holes in the copper sheet and 3 holes more in the base from left heatsink.

Terribly sorry to tell you this again, but from a thermal point of view, this is a little stupid. 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.

In first post I stated I want to put a copper heatsink passive cooler but once checked performance I saw copper absorbs fastly heat than aluminium, but effectively this heatsink needs fan to dissipate the heat. Aluminium transfers the heat to air the easy manner than a copper heatsink.

Project changed and copper heatsink will have 2 front and 2 back fans blowing air heatsink.

I added copper sheet for sdrams in back of rear heatsink:

The idea is to show you what cooling systems (copper and aluminium) have the best performances on V5k6 Gold SE :)
