My Ek x1900 water block...

Hey all,
Just got my Ek x1900 water block in the mail. Here are a few pics. :D

Block came in excellent shape. Base does have some very minor milling marks. But a quick 30 second lap job solved that problem. Milling marks were very slight, and might not have affected temps. I did not do a before and after test.

As you can see temps for gpu are 44c, which is 2c cooler than with my Maze4. Ambient temp is 21.5c. Minor quibble with the mosfet cooler. Didn't come with mounting screws, so I used a couple from the stock heatsink unit. Also while temps for mosfets are better, not as good as I thought they would be. But again a minor quibble.

For some reason a steel shim was placed between where the mosfet cooler and the block attach. When doing test mountings I found the shim to be unnecesary and so didn't use it.


All in all, this block rocks. Build and finish are top notch. Packaging was fine, with the block placed in bubble wrap and securely placed inside a well taped box. Comes with easy to understand and follow directions, for those who need them.;)

On a scale of 1 to 10 the Ek x1900 gets a 9.5, excellent but not perfect.

I highly reccommend the Ek x1900 block...

PRETTY!

Thanks for the mini review....

red x's abound..... Damn work proxy blocking your domain...

Looking good..


Eddy: Nice work on the bottom side cavaties. Way to keep the weight down. That block had the posibility of being an absolute beast in terms of weight.

nice would be better if it came with mounting screws ... so you used mounting off stock x1900 heatsink ?

To bad it isn't shipped with screws, and to bad about the mosfet cooler, but apart from that, DangerDen has to make an effective one to beat it! You could get the mosfet block from alphacool, they have two differen types, one with G1/4" thread, and one for 5mm hose:

Might get that one instead of DangerDens then, it really looks good :D

I am sorry, but I must of have screwd up the screws :slapass:
I am glad you like the block. :D

Dayum eddy, but you make them purdy... I am *sorely* tempted. But i want a delriiinn tooopppp... ;p

BTW, you still make the single Corssfire-ready block, yes? I was thinking of using one barbs "up" and one "down" since my pump is on the bottom of my case...

Looks very promising Eddy! Keep up the good work!

Sure your blocks will become a great succes!

If DD's block hasn't arrived soon I'm going to by it as well, I need one :D

Yes, the crossfire mode alowes you to have fittings on different sides.
The delrin top... I am seriously considering in doing delrin versions of all blocks.

This cooler looks very good!:eek:
Congratulations!

Would be nice :D But I'm still going for the plexi top, as it looks better with the rest of the system.. I'm getting pretty sure that it's one of those I'm buying ;)

Same here. Plexi is better for the optic than delrin. ;)

God damnit, add fins to the vreg cooling part...those little chips get soooo hot. Look at his ATI Tool temp reading, almost 75C! Add fins! :eek:

U could really use some lapping there huh..

its near impossible to lap the entire base of the X1900 block (IIRC) because the ram and gpu parts are of different heights.you can lap one, but the other one wont get touched.

If so I know what block is gonna get strapped on my upcoming 7900GTX ;)

Those temps are better than with the stock Ati vreg cooler. Under typical gaming situations vregs will not hit that high either.


Great job on the block Eddy! It was only missing two screws so no worries. Since the barbs are threaded in the copper part of the block there is no reason to fear the acrylic will crack...

Sweet. Ill probably get one either way in a month or two, but seeing as there's no window in my case, id rather have the extra peace of mind (im clinically paranoid) afforded by delrin :)

you need to take that VREG thing off there...

:(

But his overclock is quiet high doesnt that effect the temps of the Vregs ?

his OC isn't that high.
mine is 690/800 for my everyday game speed.
I've never seen mine go above about 55C.
I've also been testing the hell out of my card lately, cause I am messing with a Accelero X2, and I use Systool to create temp logs of my PCB, Core and Vreg, and in all my temp logs of the Vreg, it's never went above 55C.

Edit:

I just tested it.
10 minutes, clocked higher, and higher resolution, and still didn't even come close to the 74C shown.
that VREG thing on that card isn't doing a thing for you...

Yea, liek Maxxx said, dont lap it.

That thing sure looks pret-E

What's the pricetag on that thing? 1/3 of the price of the card, methinks :p:

odd my x1900xt is showing 52c stock speeds. I cant see yours only going up 3c when overclocking that much. but maybe its not that effected by core and memory freqency changes ? im no expert just an observation.

difference ambient temps? :stick:

ya, with a simple 120mm fan aimed at the card my vregs max out at around 55C as well while overclocked to 720/1600 w/ 1.5vcore.

even so the difference isnt going to be that big.

It's 72,8€ or 86,72USD.. That's shipped to Denmark ;)
I just made an order for one, lokking forvard to seing what it can do with my card :D Ordered it without the power reg. cooler, as i have a dream of one day making a loop for all mosfets and including it in that one..

Okay, for all the Vreg freaks who are saying my temp is high.

1) Temperatures have actually gone down over stock vreg cooler.

2) In that screenshot I am punishing the card with very high volts.
VGPU 1.575
MVDDC 2.3
MVDDQ 2.0
VDDCI 1.580

Also consider this case places the card upside down. I don't know for sure how that effects the reading but it might. It is still cooler than it was with the stock vreg cooler and that is without the volts turned up!!!

Hey Kunnak, pump some volts through that thing and watch those temps soar...

That looks excellent.

ok...

if your temps are high...
how about sending your videocard to stock, then run it again?

I ceratainly am not pushing 1.58 volts into my VDDC.
you say we are wrong about that thing being ineffective, well, a easy way to prove it, would be to simply run the test again at stock, and post that...

Never said you were wrong, nor anybody else for that matter, simply said it is doing better job than the stock vreg cooler did. Will rerun test when I get some free time and post it.

P.S. Sounds like your a-scared of a little ole voltage... :scope:

if you think, calling me chicken, is gonna get me to take a chance at frying my card, your talking to the wrong person.
say all you want... cause your just wasting your breath.

I've heard of too many videocards dying from 1.5 volts on the VDDQ voltage, cause thats a volatile voltage.
I am not gonna mess with it, just cause you wanna say I am scared to do so.




Fixed a Typo for you Eric(k) (sorry cant remember if its k or not.. i know too may erics on the forums)

will the block fi x1900GT´s?

anyone know?

yes, it fits fine, there's like 2 threads on this already, search button ftw :)

Looks like you were able to get your hands on some Predator Blood.

That IS extreme.
