Signs of corrosion?

[pvtdonuts]

Well I recently added a pair of OCZ Flex II ram and put it in the loop with my fuzion and BIX240, today however, i noticed the tubing getting cloudy where water enters the manifold for the and where it exits. It seems that only a small area of the tubing is cloudy and it is not an even coating. Could this be a sign of corrosion? Sorry I don't have any pics, I'm at work, but I will try and post some once I get home.

Could just be from dirt and stuff inside there, did you clean them out first?

Are they aluminum tubes inside or brass/copper?

[pvtdonuts]

I flushed them with distilled once but it might have not been enough, the Flex II's are all alu, which I know is a big no no, but I wanted to give them a shot. I'm running distilled and pt nuke so I'm hoping its not any sort of growth

[SparkyJJO]

well... alu with no anti corrosion stuff could be an issue but I don't know how long it takes for it to start. How long have these been in your loop?

[pvtdonuts]

Not long, I would say alittle more than a month? I'm thinking of draining the loop and checking out the fuzion just to make sure and then just taking the ram out of the loop, but if it isnt corrosion I may keep them in the loop

PT Nuke does not offer ANY protection from galvanic corrosion.

You need to add some type of antifreeze additive.

[pvtdonuts]

yes I know it does not offer any corrosion prevention, I was simply stating what I am running the loop on. What would you suggest adding?

[aspire.comptech]

Personally to be on the safe side I would say 30% concentration of antifreeze mixed with distilled water and PT-Nuke.

[Sparda]

Already a little more than a month. I curious to see what the plate of the fuzion look like. Should add the additive when put in a new fresh distilled water not after some time. Pentosin or hydrx would be a good start though I heard some slimey problem with hydrx.

I have OCZ Flex also, they are aluminum spreaders, but interior of barbs and water chamber are sleeved with copper...

It's not corrosion, could be flux from your radiator.

Which radiator do you have? Did you flush it properly prior to inserting it into your loop?

I'll post a link that explains the materials the "water chamber" is made of...

As Xavior stated the new Flex II sets are completely alu, I emailed OCZ to be sure when I got them. The older Flex series is sleeved with copper. The rad im using is a GTX240, I flushed it with distilled, boiling distilled, and then distilled again, so it should be pretty good. Also the funny thing is that the cloudiness is only coming out of the manifold the ram is attached to. I will take some pictures before I decide to flush it

I'm going to break up your quote, so you might better explain what I think I read above:

"the new Flex II sets are completely alu, I emailed OCZ to be sure when I got them. The older Flex series is sleeved with copper."

That statement you made, sounds to me like you wanted aluminum and not copper. For goodness sake WHY ????

[pvtdonuts]

Not that I wanted copper, I could not source the older Flex II's. I emailed OCZ to ask if they were sleeved with copper as with the older series, but they told me they were not, yet they assured me there would be no corrosion...yea right. But I gave them a shot anyways, sorry for the confusion triple R, anyways here are the pics.

-in the top pic the left tube us getting cloudy while the right one is clear, same with the 2nd pic, the one going into the manifold is getting alittle cloudy

Well i took the loop apart and found this in the manifolds, however the block looks ok so im hoping the radiator is ok too, but I'm definitely taking the memory out of the loop, does that look somewhat like corrosion?

Could you empty the loop and look at the water? See if you there are tiny flakes of metal in the water? A coffee filter should do the trick.

[pvtdonuts]

flushed it and it doesnt look like there are any flakes in there, the other pieces of the block are a bit clouded, but the copper is fine. I'm just gonna keep the dimm's off water and run then with a fan blowing on it and probably get a TDX to replace the fuzion, on the topic of blocks does any one know where I can get a XSPC blade edge? Should I replace all the tubing as well?

[melanko]

Stupid OCZ. Teaches ya better than to watercool your memory sonny!

Next stop from here is to get some waterblocks for your HDD's.

[Sparda]

Look fine to me...Glad to see that.

[RealRedRaider]

Pvtdonuts,

Why would OCZ change the FLEX II to a straight aluminum water chamber, when they had the old FLEX with copper sleeving ??? Makes no sense..

I believe I found the culprit contributing to your corrosion.

In the name of everything Holy, why did you use a "Koolance" 4-way ALUMINUM splitter, before and after your memory.

Dude, I have the old FLEX, no corrosion, no "KOOLANCE" 4-way corrosive splitter.

Now that I've seen these pictures, I think you owe the OCZ Flex II an apology. I can only assume in this picture, that your loop order is:

CPU / 4-way splitter / ram .....

If so, then I found your culprit, damn that water is cloudy right after that "KOOLANCE" garbage.

[Xavior]

Those aren't Koolance splitters, they are included in the Flex II package. -.-'

[RealRedRaider]

Those aren't Koolance splitters, they are included in the Flex II package. -.-'

They damn sure look like "KOOLANCE" splitters.

So you people are saying;

OCZ upgraded their FLEX II memory by removing the copper inserts in their water blocks and also rebadged some "KOOLANCE" splitters and included them in the deal??? Am I on the same page as you guys.....

Again I have the OCZ FLEX RAM, no "KOOLANCE" splitters were included + sleeved with copper = NO CORRISION .....

Should probably put those babies on e-bay, then go Back to the Future with the origial OCZ FLEX RAM. You can still buy them...


KOOLANCE thinking:
...Lets see, if you replace the compression fittings with barbed fittings, package it with some ram, take our name off... Damn, we might finally be able to sell one or two of these monstrosities...

[septim]

if you want mix metals, put in some anti corrosion...
otherwise just blow some air on rams and keep other components of the loop, i don't see why you'd need to replace the fuzion with an mc tdx...

True dat.... :up:

... or get rid of the "KOOLANCE"

[pvtdonuts]

Lol, the mc-tdx is to replace the fuzion which is going into another system, so I wanted to make sure everything was ok with it before I made the jump. Yes those manifolds are from OCZ, they include those, which are also alu, as well as some barbs and some opaque tubing. I'm not sure I can return them anymore since the tubing is cut up, so I will probably use them air cooled with the barb covers on. Should I flush the rad to make sure everything is ok? Also to 3R, OCZ did infact downgrade their FLEX II series by using all alu, with a couple steel parts, but other than that there is not a trace of copper.

It's hard to argue with the TRUTH... :shakes:

[RealRedRaider]

It's hard to argue with the TRUTH... :shakes:

I'm with you on that....

Remember I said it HERE first:

"R3 will never again buy an OCZ water cooled product...."

Glad I'm the proud owner of OCZ's old RAM....

[pvtdonuts]

Haha, well I was curious as to see if I could actually take these things off and get some better cooling so I went ahead and took them apart, made sure I was very careful with the actual dimm's b/c OCZ used the super sticky thermal tape on these, heres the pics! Just in case anyones wondering, the laptop I'm using while im waiting for the new parts is a XPS1330

[RealRedRaider]

Interesting.... Thanks for giving more "internal computer porn".... They should advertise what the water block section is made of...

[Helfarch]

How do you tell the difference between sleeved and all aluminium Flex IIs?

[pvtdonuts]

The Flex I's are the large chrome heatsinks with a single inlet and outlet on the DIMM and they have copper sleeving in the water channel, the Flex II's, which are what I have, are full alu but feature 2 water channels that go directly over the ram chips themselves. Great design but poor execution, if only these had copper sleeves...

[Helfarch]

Bugger

Not that the Flex II actually need to be watercooled I haven't had a single issue with them 'running dry'. It does after all state/imply in the OCZ info that water is optional.

[pvtdonuts]

Of course, but if your water cooling and they provide everything for you, then hey why not, but i'm replacing the sinks on these with thermalright HR-07's with a 92mm fan to try and get the clocks alil higher
