I bought a 6950 recently and after finding the shroud on it to be rather ugly, i decided to try to build my own shroud made out of metal, instead of plastic.
I have a pair of 80ml slimline fans coming any day and might use them or the original fans, not sure yet, heres a few pics of it so far, i made it from a metal filing cabinet draw that was laying around.
Its a work in progress, i also took the opportunity to lap the heatsink base too why not.
Its going to have an "army" theme to it when finished haha, like it came out of a tank or something, a gpu for the army lol.!!!







i will post some more pics of progress if you like. Something a bit different anyway haha.:p

I'd have gone with a reference card and I don't think these kind of stuff (ghetto mod) is much worth the hastle anymore. Reference all unlock and have Volterra's. Other hand, non ref are cheaply made and don't unlock much anymore. You should be able to still find a reference card over there. ;)

A mock up with fans, this is an engineering challenge to get it to work, it may not but , gets the mind working and is creative .:)
If i can get it to be practical and functioning , then i may spray paint it in urban camo or something,

You're going to reduce the performance of the cooler. That metal piece would cause air resistance, also, the plastic was a more open design. Not sure where you're trying to get with that. Just for looks, eh.

And it doesn't... a rough piece of rusty metal has no turbolance to make it vent better. All it does is to tank the GPU and rescrict airflow. If you noticed, the plastic cooler is feather and shaped in a way it makes an "open design". It already has the spaces to vent it out. I'm sure this is going to make it work worse than stock. I mean, look at his second pic. He locked up the card with metal garbage.

From his first post it seems like his concern is the way the card looked. The shroud is not even finished I wouldn't say its garbage.

...which is more important than how it performs sitting upside down in your case under the desk, right? He's making it out of garbage. That is what is it. Garbage is garbage, GIGO.

Look at the stock cooler, notice it's curves? It's made to produce positive airflow. This idea is too tough to be practical with that piece.

I am not sure that he cares how it performs. My main concern is performance but I push my stuff to the limit. Some people like looks and maybe the feeling of modding their own stuff. I think its great when people mod things. He may take a temperature hit but I doubt it will be much. I would think his shroud will effect how loud the card is but then some care less about sound. I guess we will have to wait for him to finish to get the results.

All im going to say is metal isnt the greatest material to make your shroud out of. I know your going for that old reference cooler look.

1st Rome was not built in a day and i do see what your on about but if he got this far there is nothing stopping him taking it a little further.

I am all for performance over looks any day but it takes time to get some thing how you want it. Shii maybe later he pick some thin alloy up to lighten and soak the heat and put more vents in it..

What you cannot argue at this time is the effort and skills he's putting in to it. Best part is he can always change it if he feels that it's not good enough for him.

All im going to say is metal isnt the greatest material to make your shroud out of. I know your going for that old reference cooler look. maybe look into a Arctic cooling accelero those are nice :)
There far from perfect 1st thing i do to those is replace the heatsinks and fans and remove the plastic crap which the later to are cheaply molded together.

Stop thread-crapping. You have your opinion, and he has his. What's important to you may not be important to him. Leave it at that and move on.

Im just playing around with ideas, whether it works or not ,meh, maybe the next one i make will, its fun.

A learning curve, theres a lot to consider , how to mount the circuit board , airflow, weight, size, thermal characteristics, which may have been good considering metal is better at heat conductivity than plastic[as far as i know]. Its challenging working metal.

It was just something i thought people may find interesting.

Who , that is into tech, wouldnt love to design there own gpu hah, lol?:roll:

I like it!

I get what you are after, and modders do not start out building those silly wire sleeeved lights and acrylic stuff in the first day. They all start somewhere :) (I hope you never do that silly pretty looking crap)

I much prefer seeing stuff like this, that is all about trying new things out :)

Metal is a much better thermal conductor than plastic so :p

Anywho, dont paint it!! and pair it up with a TUF series ASUS motherboard ;) Would be bad ass looking. Specially if you beat the crap outta your case and then cammo paint it ;)


EDIT: You can mod the backplate to provide more airflow or stagger the fans, one in one out to play with cooling properties if your case has enough airflow ;) I have not played with newer gen cards, but traditionally GPU heat is never an issue with clocking ATI cards, its the VRMs that overheat. Leave the rear fan blowing down/in and the one closer to backplate blowing up/out

Thread crap? I'm trying to make him realize he's wasting effort on a rusty piece of metal. See the other suggesting an Accelero Xtreme? Oh well.

Just make sure you don't short out anything on the back of the card with all that metal. Rest is all fine. No need to worry about turbulence or anything. Its just 100 cfm of air at max.

You're being a dick and totally crapping on this guys thread. If he wants to mod his shroud, even if it makes the cooling perform worse, that's his business. It's cool he decided to share it with us, which may not happen in the future if douche nozzles like you repeatedly bash his idea.

It's his hardware, not yours.

wow

its getting hotter.
theres many things you need to consider before you mod it, like how good material that you use, the contact area, airflow, your load etc

@ John Doe. you know theres a saying for you guys? it goes something like " haters gonna hate"
if you cant respect someones imagination and hard working skills, dont DE-motivate them with your BS. I guess you must be someone who likes everything ready made. But you must learn to appreciate others who like to do things like this just for the sake of it.


Wheres the fun in fitting a dumb looking accelero extreme on such a beautiful piece of engineering?
yes i think the accelero extreme is ugly.

also as long as this dude here has enough space for air to go in and an equivalent amount of air to come out, he will NOT have any problems.

Infact a well designed shroud is better than some open space, because you are improving airflow and hence reducing turbulence.


Also Sub'd :D

If you really gonna do that mod, which in my opinion, could look amazing, when done right, then i see 2 possible error sources, which may give you problems in the future...
if you want to cover the whole card up, you need some kind of spacer between the back of the card and the metal, or else: "BRRRRZZT".;)
second...you should really think about, if you dont want to make some ventilation cuts in the backend of the shroud...
its open to give results, but i also think, that in the way it is now, it may block your cooling efficiency...im not sure tho, so better test it yourself.
Only results can give us clarity!;)
