All that means is that only 5% will fail instead of 10% (made up numbers). There will still be defects.

How about 0.1%?? That's a typical out-of-the-box fail rate with good QC. I was a member of a QC team a few years ago and that was what we found to be acceptable...one in one thousand fail rate.

The magic point I think is that for maybe 1-2C you'd take a chance that something was slowly degrading in your rig, such that you might have a catastrophic failure and never know it. It's a small chance, probably very small given all that's gone into it, but it is there. And a warranty is only going to replace that $70 block, not the 000's of $ in other items that might go poof in the night...

I like the block and have many Swiftech products over the years, so this is not a company fault. It's just what you are comfortable with for risk.

Kinda funny though how many pages we can argue over 0-2C improvements :) but that's us!

Very very nice block

That's why I said they were made up numbers. It totally depends on the manufacturing process and a lot of other things. For the stuff I have been designing recently there is a 1 PPM acceptable failure... I tell you a lot of thought has to go into that.

The chances are small but they are there none the less.

BTW I minored in statistics in manufacturing/QC

Bun-Bun, are you saying the Apogee GTX has a chance of failure but other blocks don't? What if one day something went wrong and a block was screwed while milling, and it leaked on you after a few days?

My Coolant = water.

I don't have any corrosion protection so my rule is no aluminium. Nice block and I'm sure it performs well. Well enough for me to chose it over a non mixed metal block? Nope, fraid not.

Hope those who buy it are happy with their purchase but not for me, rather safe than sorry.

I am pretty sure this corrosion deal is being completely blown out of proportion for this block. I am confident Gabe is not going to release a product that will fail and ruin are systems. There is a five-year warranty to top it all off. The only reason I didn't order this block is because I am cheap. ;)

well, I believe plating or anodize is good enough for a cpu block. defects happen. but generally the defects that you found on the block on your hands will be more likely from inaccurate process rather than plating. that makes plating a rationally small problem.

consider this, if the plate fails and corrosion happens, it can still be plated again. but if the block is not accurately machined. it often has huge impact on the cooling result and mostly can not be fixed.

say I'm using whole copper block and what do I get, I can sand it from time to time. I don't think it's big gain..

any way, I hope swiftech to change their mind and make some brass version. water cooling is becoming more and more customer oriented. maybe it's not just safe or performance wise. people just want it that way, as the same people just want their pc water-cooled. deal with them. even beautiful aqua plex blocks has copper option.

and the company has to be around 5 years to honor that warranty:D

Wait a minute, are you saying brass corrodes itself?????

you missed that he said aluminum.

No, your post in the other thread, and according to that thing, it seems that zinc and copper corrode each other (which they don't, brass hello!)

Hey what happened to brass tops? [choke choke cough]

Whatever happened to people complaining about brass tops? Seriously, I thought brass tops were supposed to be good, and now this is being shoved in my face?

Yea, but your post in the anodized aluminum thread implies that brass and copper WILL have problems ;) Zinc was listed even farther away from copper than aluminum.

no, his post (Gabriel Noraa, post #39 as referenced in post #211 of this thread) says:

For me, mixing Aluminium and Copper/Brass in the same loop it's totally forbiden. Never again.

I haven't read the whole thread, just parts of it so if I say something taht has already been mentioned please do not get upset. I usually hate stepping into these "battles" but I have some insight for the doubters. I have several friends in the Aeronautical industry. In planes they use aluminum in areas where it contacts other metals such as stainless steel and titanium which just as easily corrode the aluminum. They take the necessary precautions and treat the aluminum with necessary agents to prevents erosion from occurring. From the sounds of it Swiftech is properly treating the aluminum for the application and there should be no worry about using a GTX in your loop. Finally if it really worries you to have aluminum and copper in the same loop just run some Pentosin in the loop for extra security.

It's when the nobility is farther apart on the scale.

[sigh]
Brass is an alloy of zinc and copper ;)
