Apogee GTX

[JoeBar]

Copper would not create a weight problem. the force of the tubes applying unwanted leverage to the CPU block is FAR greater than any effects caused by a heavier block.

Hadn't thought that. U gave me a new perspective. Thanx...

Obviously, you would use silver plate instead of going solid silver because otherwise it might start corroding your copper - lol

Hey, the base plate of the Storm G5 is >99.995% (just a quote, not a fanboy remark) pure silver. I honestly don't know whether the internals are copper or silver, but the top is delrin. Anyway, I've never heard of corrosion from owners. The point is why silver plate for looks when you can design for substance.

Um, the corrosion comment is an attempt at what I call 'humour', you may know it as 'joke'.

That said, 99.995% pure silver sounds like a suspect choice for a block base (or top) but as for price: apparently, silver is a something over A$500 per kilo, so if the top masses 50g (a generous estimate) you're looking at about A$25 in materials, maybe US$14, something like that? Probably would be a less in practice as you'd get the mass down as low as practical.

But if there was any benefit, would it be enough to beat a D-Tek FuZion, 9 mounts out of 10? Sounds unlikely, nobody seems convinced that the alu block helps worth mentioning; so unless they are going to put some serious fins on the top it's not going to make a lot of difference.

Just speculating, but it would seem the gain they did get was from spacing the barbs, which was an overdue mod really... OTOH, maybe what they need is the inlet flowing straight at the center of the block, more like a FuZion. Maybe someone who knows can say whether D-Tek are getting a lot of impingement style turbulence benefits that helps the edge ahead of the Apogee GT in almost all tests I'd consider actual 'tests' as such and not blatant PR.

The military does't have WC rigs that gets trashed by corrosion, we do.

Incorrect - the military DO use WC'd rigs... As do NASA and ESA. Trust me on this one... no more can be said on the subject

There's a PA120.3 in the International Space Station isn't there!

its hanging out the window to get the lowest Ambient temps :-P

They are using Petra's PT NUKE as well.

There are bomb disposal robots, lasic eye surgery lasers, hazmat environmental control robots and many other such things around with ThermoChill HE Series rads stuffed into em...

Please remain where you are. Operatives will be over shortly to collect you for debriefing.

EDIT: And the NSA. Guess they have to cool those Rubicons somehow.

I know you meant this in humor but...

I don't think placing a rad in a vacuum would work very effectively as there is no physical medium in which enable heat transfer. There might be a benefit from black-body leech but, unless I am mistaken, a rad exposed to a flow of air or water (or other thermally conductive medium) would be more efficient than exposure to mere entropy of even the coldest vacuum.

I've actually wondered about things like this in aerospace applications but naturally, not having access to a near absolute zero vacuum I haven't been able to test the notion. I don't know anyone who has access to such things either.

[ramenchef]

Well the heat could radiate from the rad into the vacuum as conductivity is not the only way heat gets transfered. Not sure how effective it would be, though.

[Budwise]

a bit OT are we? LOL

[Sparky]

Obviously, you would use silver plate on copper instead of going solid silver because otherwise it might start corroding your copper rads - lol

Copper and silver don't corrode each other, aluminum and copper do.

Hehe just a little.

I am looking at the temperature, and if you have liquid moving through the rad via a pump, the RAD would absord the temperatures............but not knowing anything about how the cold of space would really affect a RADs heat transfer properties I was just looking at the basic COLD of space.


Space is Cold and thats all I was looking at.


hey Marci, not that you can confirm or deny this at this time, but see if you can get one sent up with the next shuttle launch so we can get ambient temps and see if we can get a mad OC on a 6800 or Q6700 ;-)

[TheReds]

We are such nerds..hahaha, debating the effects space would have on our overclocks lol

Has anyone recieved this block yet? Im anxious to see some tests!

peace

[Mr. Peanut]

The forum ate my post about how we should listen to Gabe and not whine about the plated, thermally conductive aluminum that is used as a heatsink.

Also, what's wrong with a little bling?

My post had some suggestions for corrosion testing on this block that must've been quite delicious. The just of it was:

TEST 1: Loop with no CPU. Only the block, a pump, and some tubing. Run it for a long time, and look to see if there is any corrosion periodically.

TEST 2: Same as test 1, except with corrosion-resistant additive to the water. Use algaeacide in both loops, simply to prevent that factor from ruining the tests.

[SiGfever]

Speaking about space really does fit this thread now, it could not have gotten further off tract.

@nik,

I look forward to the test results so the data can speak for itself.

Copper and silver don't corrode each other, aluminum and copper do.

I think you will find that silver is capable of inducing galvanic corrosion in anything besides a handful of obscure alloys, gold, platinum, titanium and graphite.

However, for those that still don't get the joke, the rate of corrosion would be extremely slow - and with deionized water in a standard cooling loop, you could probably go a decade or so before you could detect it.

Just guessing on the time-scale here, haven't done any bogus calculations. However, if you were to intentionally induce galvanization, then you would soon see results, even from gold and copper (by which I mean the gold corrodes the copper). This is just electroplating in reverse, if that helps make it sound more believable.

[JamesAvery22]

Are there any pics of the bottom of the Al top? Maybe there are spots where the dimensions are too thin for delrin to be used. Machining brass sucks and is stronger and harder than Cu and Al. Don't think anyone would be quick to re-tool the fab plant just for a brass top.

[Plywood99]

This whole corrosion thing is blown way out of proportion. EDITED FOR CONTENT-PB

[serialk11r]

Wow, copper is in the same group as silver. You really think it would cause problems? All those brass instruments with silver bells would be completely destroyed already if it were that bad.
Anyways, I don't see how the aluminum top would effectively cool anything, but I guess it was more for the wow/bling factor. But I don't like the look.

[Plywood99]

You do realize that anodizing and plating are different right??? And the pictures shown in that thread, obvious they did not do proper measures when using mixed metals.

Why do you think cars can go for years on the same coolant even though having mixed metals in the loop. Lets see, iron, copper, brass, aluminum, plastics. All sorts of stuff. How many Koolance systems do you hear of being destroyed by corrosion? Ever heard the saying "an ounce of prevention?"

It's called doing research, real research. Not just hopping on a forum and asking a question or two. But people now a days want to be spoon fed. Why exercise that grapefruit on top your head when you can just hop on a forum...

My Swiftech blocks all ended up the same as yours despite running 10&#37; Zerex / 90% distilled and flushing/refilling with fresh mixture every 6 months... MCW462, MCW5002, MCW20, MCW40... all the same... DD original Ali Top'd Maze4 likewise... Innovatek Rev3 CPU Block likewise...

All anodised... anti-corrosive additive used precisely to manufacturer's mix ratio for proper protection rather than clear-tubing... all still corroded within 18 months. The swiftech blocks ended up with corrosive pits around half a mm deep iirc... s'why back then I went with dangerden - no aluminium used at all...

From that thread. Even with regular water and coolant changing and the proper amount of additives, corrosion still occurred.

I want to ask, who was that directed at?
Well I've played 2 brass instruments, and I can tell you, the plating on the tapered insert of the mouthpiece will get way more rubbed off than that top's plating ever could, and the plating is still there... I've seen a gold plated mouthpiece that has no brass showing from underneath. I seriously do not think the nickel plating on the top can come off, and damage the loop.
Cars can run for years with iron, aluminum, brass, steel, etc. but the engine blocks do get corroded, just not to the point where there would be problems.

[Plywood99]

It was directed at mcoffey, not you serial. And the comment from Marcy makes perfect sense. When you have a inferior anodizing, and wrong mixtures, (no not saying Marci mixed wrong), problems can and will occur.

Ive' used some home-brew blocks that were nothing but a copper plate with aluminum channels soldered to it. No problems when used with the proper ratio, and the right kinds, of chemicals. But I did get sloppy once and not put proper ratio, one block corroded completely shut on me. Note this was my fault, not the blocks.

Things are simple now though. If running mixed metals use Koolance coolant.


And besides, as was mentioned the GTX is PLATED...
