5 out of 5 eggsWorks well

Pros: Seems well thought out/designed. This fits my Asus 4870 well even with the ram heatsinks on. 3/8 I.D. tubing from a Thermaltake kit. GPU temp has gone from 72C to around 50C while playing Crysis.

Cons: Wish it was copper. But the whole dissimilar metals thing doesn't hold up because all the radiators are aluminum. Copper just transfer heat faster/better.

Other Thoughts: Water cooling works, but you need to be somewhat proficient at building and modding PCs. This was my first attempt, and it works well. But I'm an old tool maker, and I've built about 15-20 PCs before.

5 out of 5 eggsworks!

Pros: works really good and the install was easy.

Cons: little washers are easy to loose

Other Thoughts: the heatsinks stay on as long as you clean the surface, stick em on, and dont touch em for 24 hours.

5 out of 5 eggsGood cheep block

Pros: Amazing little water block. Has TONS of potential.
In my setup, set on a XFX Nvidia GeForce 8600gts overclocked to 800 core 1800 shader. Highest recorded temp of 51c. Idles at 43c.

Cons: Made out of Alum instead of Copper... But for $25, what are you gona gripe about?

Other Thoughts: They could make a copper version of this, and I would probably get it.
Could have a better lapping job, it's kinda rough.

5 out of 5 eggsAmazing value and quality

Pros: I first installed on X1950Pro. Now running on 8800GT BIOS volt modded to 1.1v and OCed to 740MHz core. Load temps are 53C (AtiTool 45min) on GPU Core and 41C idle. Hooked to Corsair Nautilus 500 external kit. I also have Delphi CPU and Zalman NB WB in the same loop with 3/8" tubing.

Cons: It doesn't make a toast.

Other Thoughts: I will mod Corsair to fit inside the case. Will replace reservoir (tiny) and radiator (cheap aluminum).

5 out of 5 eggsZALMAN says it all...

Pros: (XXX EDITION)GeForce 8600GT's in SLI config...with preoverclocked cores at 620/800 and I over clocked that to 690/860. EVEREST measures GPU1 at 50DEGREES C- and GPU2 at 48DEGREES C- and since this is all in a passive cooling system I also have my CPU cooled on the same line and it's an AMD x2Opteron 185 and its overclocked x5%, well its 44DEGREES C-. I'd say thats pretty impressive...

Cons: They do take up some space...sticking out just a bit prevents me from being able to useing 2 of my PCI slots.

Other Thoughts: Well designed...and ZALMAN means a quality product.

5 out of 5 eggsAmazing Results....

Pros: Running GeForce 8800 GTS's in SLI configuration...currently, One is liquid cooled with Zalman's Reserator 1 Plus (WHICH uses this exact W.Block) and the other is on a stock fan...and the difference is approx. 10 Degrees...that's why I just ordered onther one for the other Card. Plus its an easy set-up. Couple of screws, slap on the thermal paste, and that's about it.

Cons: ...you've got me

2 out of 5 eggsx1900 XTX and Zalman cooler

Pros: Looks cool ? Keeps core cool.

Cons: I hooked this up to my x1900 XTX and my games are crashing now and I'm getting a heat warning from my catylyst control. I have all eight heatsinks on all 8 memory chips, just like the stock cooler had. I have the vga water block on the card exactly how they showed it to be and am getting 60c temps at idle from the core reading.

Other Thoughts: It must be something else that needs to be cooled that this kit doesnt come with. I'm baffled.

5 out of 5 eggsCold block

Pros: Use a 10gal tank with distilled/RO water and micro pump. Chilled the canada VGA card from over 100deg to 45deg at full load and OC. Idle at 31deg.

Cons: I need to buy more now.

Other Thoughts: Best VGA block and kit for the dollar.
