38xx Zalman Waterblock

post #1 of 12
Thread Starter 
I've spent most the evening here trying to find a dealer in the US that sells the Zalman ZM-GWB 3850/3870... No luck so far.. Seems that the UK is about the only location that has it..

Anyone know if the US has this or is getting it??

Wow they never cease to amaze me with how complicated they make their blocks...........

Since you have a mostly aluminum loop I'd say get the Koolance one. It will be much easier to find and it wont look like it was made in China.

That block is crap.... just look at bends and restriction and poor flow....

IDK about poor flow (at least not with my pump) as much as I do agree it looks less than great.. But looks aren't everything..

Thing is the Koolance is near $100.. OUCH.. For a $120 video card? Pft!..

But seeing that the Zalman is not really available here, I guess I have little choice.. Maybe I'll just make my own.. hehehe..

LOL..

Ya, I am also looking into the Koolance model.. It looks a little more solid to me.. But I was really just wanting to see what the price tag was on the Zalman..

I have to admit, the zalman does look rather cheap.. Some of it looks as if they took multiple blocks and just screwed them together, then (as if at the last minute) the remembered to add the vreg cooler to it..


Thanks for the input guys..

None the less, it looks as if it's not here in the US yet anyway.. Koolance here I come..

Well right at this moment its all been dismantled.. I'm waiting on myself to make up my mind on a new motherboard.. Today I'm set on a Max. Formula.. Tomorrow, who knows..

My setup is not really a normal setup.. I've always wanted to tell people about it, but was never really asked.. So, here is the long version.. LOL thanks for asking..

I'm in the business of selling 'Point Of Use' water systems.. These 'POU' systems consist of bottless water coolers using a sourced water supply and reverse osmosis filtering..

That being said, I have access to all sorts of product that most 'modders' haven't seen before.. Tho as of late, these items are being seen more and more.. Mostly because they are just plain better, safer, and cleaner looking than the current compression fittings and tubing used in water filtration (and now CPU cooling) systems today..


Pump: Aquatec 'On Demand' 25psi output.. Not much keeps this thing from flowing.. Its powerful but bulky..

CPU Block: Zalman WB3.. It works pretty well..

N.B./S.B. Blocks: Zalman GWB1.. Had them for years, they fit well as bridge coolers instead of VGA coolers..

Video Blocks: Zalman GWB2.. Currently being modded for new fittings..

No Radiator-

Chiller: I have 3.. Water coolers..


I'm testing a used water cooler atm that has an awsome compressor.. So far it chills very well but needs a different thermostat b/c 0C is way to cold for Indiana summers (condensation)..

The best part to my setup isn't any of that stuff really.. Thats all pretty basic.. Tho the chiller helps me to keep only one loop for everything...

Quick connects.. These things are awsome.. And with a good pump, flow isn't an issue.. Even with a $19 pump, I still had good flow..

Quick connects are just the coolest.. Nothing to tighten, no compression fittings going bad and leaking over time.. Simply put, you just plug them in and you're done.. They remove just as easy..

These things are proven safer and more leak proof than compression fittings.. Plus, they come in all sorts of shapes and sizes.. (from 1/4" to 1/2' tubing and fittings)

Most H2O users will say that this is less effective than the 'normal' means of cooling, but I firmly disagree.. Using a radiator with 2 120mm fans and a $19 pump, I kept my cpu at 28C idle with a 100% oc.. I've used both, and this style looks so much cleaner..

Sounds good but don't try to use anything copper in that loop. I have seen pics of that very CPU waterblock corroding away. Infact here's one.

I'll pay the extra $$ for an all copper and brass loop.

Not sure I follow you... You said don't use copper then you say use all copper.. Did you mean don't use GOLD? This Zalman is gold plated.. Plated over what IDK..

Nice pic:
That's pretty nuts.. I'm starting to see that very wear on mine.. I couldn't get mine apart to clean it, so I had to soak it in a citrus solvent.. Cleaned it pretty well, but it still has some discoloration to it (just like the one in your photo)

Water is such a powerful thing.. There isn't really anything that it doesn't break down over time.. R/O or Distilled water acts like a sponge and wants to absorbe just about anything and can be particularly damaging to copper and brass.. Plastic, however, is a different deal.. If they could make a plastic that transfers heat like copper that would be a good day...

Thanks for the heads up on my CPU block..

Lol I meant don't use Copper in your loop with your Aluminum blocks. Aluminum + Copper = BAD BAD THINGS. The base of your CPU block is gold plated copper and if it is beginning to corrode then that means the bases plating nor the tops anodizing isn't perfect. It will never be perfect. There are liquids you can buy that hinder it but over time their ability to wears off. I will only use copper, delrin (Plastic), and brass because they do not react with each other. For more info on this research Galvanic Corrosion.
