Looking forward to your results :)
Quick Update.. I Overclocked it to 850 Core / 1200 Ram.. Furmark 1hr. Temps 43c Core 1 Core 2 45c
Stock voltage or ...?Quote:

to answer some question
I put the voltage to 1.25 Vcore and it runs 1000mhz No issues.. GPu core where 45/ 49C running Furmark for 2hrs.
The Card overclocks nicely but when you turn up the juice on Vcore the VRM Get HOT!!!! The Final REV of the block going to have cool water going over the VRM..
Screen shots to follow.. sorry for delay been busy getting ready for holiday
The VRM cannot get cooler with this block as the water is so far away from them... Think about it ;)Quote:

The max stable overclock i've been able to get with the 5970 is 955 on the core, 5270 on the memory. I've only got an Air cooler at the moment though, expecting my waterblock any day now :D Impressive results there Evilclocker! :) Are you finding the limits or just playing it safe?
Its because manufacturers focus more on the core temps, as they are the most critical part of the card, so they (nearly) always have better cooling than the VRM's for the same water block. My temps sit under 50 at full load (same card and waterblock but a Koolance ERM K2U 5 loop watercooling setup)Quote:

In hindsight, I wish I would have used rubber gloves to install them.
What I have Found out is the VRM Get HOT Fast When you Overclock! My Card Runs 1000Mhz on the Core 1250 on The Ram.. but when you fireup Furmark.. The VRM Gets 85C Which is Way cooler then Aircooled.. DangerDen has a new Rev of the Block I will have next week to have water cooling the VRM Also.
I found that 1.25 Vcore is need to get 1000mhz. Keep in mind I Running a Dual Boreas WaterChiller.. My Water Stays at 20C
My Card Idles at 22C
What kind of rad/pump do you think would be best suited for this waterblock? I'm thinking about a XSPC RX120 http://www.pccasegear.com/UserFiles/xspcrx120_2.jpg radiator on a single loop dedicated just for the GPU. Something like the BFG did with the GTX295 H20C. What do you think?
Huge change of mind from the guy who used to screw aluminum plates on his blocks to cool VRMs :p:Quote:

Any update on the new revision of the block which runs water over the VRMs?
Yep.. have it friday
Except then that was enough. Now with the 58/59 cards the VRMs are really a limiting factor. It wont be the gpu temp thats holding you back, its the VRMsQuote:

I'm running two MCW-60 with a pentium II heatsink that I took a hack saw to cooling my VRMs. They are definately the limiting factor. I have 950/1250 @ 1.225v (can maybe go lower) and my VRMs hit 90c in Unigine Heaven. I can't run Furmark for more than 20 seconds or they pass 110c. Don't know how high they will go because I'm not willing to test. Not sure I want to cough up the money for a full cover, but I need to do something better than this. The GPU cores don't hit 50c though.
I'm thinking I may get some copper tubing and sand one side flat, and hook it up to my loop. Should at least be better than air. Any opinions? Suggestions?
i was thinking a while back about using copper pipe to make a loop that goes over the RAM/VRMs. not sure how bad it would be to solder a copper pipe to copper heatsinks. give that the whole project could be done for under 20$ it wouldnt be a waste at all if you had to do it for each new gpu you buy.Quote:

but hey, if someone wasnt to do a cheap mod for their 700$ video card, i sure wont stop them.
i also wonder if the UNISink that swifty makes will even work well enough for a 5970. i havnt paid too much attention, but im pretty sure they didnt release it yet, or if they even can.
I like these two blocks the best (for vrm cooling)

I think they just need to widen the block to the right a little more and stretch it out slightly past the VRMS on the right edge. That way they can get some water flowing directly over the top of them. As it stands right now, the flow is close, but not directly over the top. I still dont know how flush the contact is on the bottom, but I'm assuming it's the same on both of them.
Ya, the heat transfer is my main concern. I don't think solder should be an issue. AFAIK it transfers heat very well. What i'm not sure about is the heat transfer from the copper tube into the water. I'm also not sure how I'll do the three VRMs between the two cores. My mounting plates leave little space so I would have to have the flow perpendicular to the VRMs.
Here are results from Final Version of the Block

wow, much nicer than rev 1 DD. Great temps all around vrm & gpu, evilclocker. Got a screenie of your max oc?
I'd like to see water temperature on this and clocks.
Well in his screen shot of Furmark shows 849mhz for core and Memory at 1200Mhz. But if I do remember he's doing his with Dual Coolit Boreas now is that just the GFX or our you cooling all of your system with the Boreas's. If just the GFX what are you setting up the temps in the Mtec below ambient and if so what are you doing about condensation.
I also have a Coolit Boreas but set up just for my CPU and NB Core i7 920 and will have my 5970 on a GTX360 Rad.
So yeah just like Eddy Ek I would like to see water temps but more looking towards others with just using Rad, Pump, Block set up.
ED
Iam runnng a Core I7 860 o/C to 4ghz 5970 1.165v 850mhz 1200 Ram.. Water Temps stay around 20-21C Running a Coolit system Boreas and Dual Freezone elites. All 1 Loop CPU and VIDEO

jaredpace , My card does 1000mhz on core max.. I get you a shoot today running furmark at that speed. Things heatup little more at that speed
If you think you can go higher (or even want to) AMD GPUclocktool raises cores > 1000 mhz, and Asus Smartdoctor increases Vddc to ~1.45v.
Jared,
YEah I have to use AMD GPUclocktool.. if I dont my screen flickers in 2d mode.. 1ghz on the core things heatup about 10c more on vrm maybe 1-2c on the gpu cores.. MY cooling systemup is pretty good
Hey Evil, could you run Furmark fullscreen? I tried running it at the same voltage and clocks as you and my frame rate average was about 190 (@1920x1200 Fullscreen 0xAA). Yours was 125. This would also explain why your current draw was only 40ish when mine was 60+. At 950mhz @ 1.225v my current draw is about 80 amps. I'm curious how well that block does under these situations. Also, it seems when using AA the current drops significantly.
Worked just fine for GTX 285. I had great overclocking results with that EK block and it ran nice and cool.Quote:

Thx :)
Scaniris, Please post your Results.. I am interested in how well the EK block performs
Ok I'll do it end of this week, I have to install the waterblock and upgrade my cooling system before (and don't know if I'll choose a single or a dual loop configuration...). But I have no chiller, temp of water is @ 24,5°C average in idle mode, and maximum 30°C @ full system load (when I had the GTX285 and the i7 860 in the same loop, I don't know what will happen with HD5970 and with 1x480 + 1x240 rads).
I made some measurements with the stock cooling system of my XFX HD5970, using Stalker cop benchmark, and Furmark. I've recorded information with GPU-Z and MSI Afterburner monitor. After mounting the HD5970 waterblock, I'll make same measurements in same conditions, and compare. Without any overclocking, I want to compare stock versus water cooling solutions. So I apologize not to have Chilling unit in my system, it will be difficult to compare my results with yours because you are using cold water (I'm really interested in your system, I had a look yesterday on the CoolIT website, nice solution! :))
Make sure you do. the 5970 does but out some heat in the loop.. I am running a single loop on my rig.. The boreas is a good unit.. but not enough for a cpu and 5970.. so I am running boreas and (2) Freezone elites.. so Most of the time My Card is Chilling around 18-19C :-)
I'll create a new post to ask my questions about single or dual loop, I don't want to pollute your thread about HD5970 water cooling/chilling with another discussion not related with main subject ;) But ok I'll post the results as soon as possible.
Hi EvilClocker,
I've put some screen shot on the HD5970 topic, but I put them also here:
Here are the temp results after 1h30 of Furmark @ 1920x1200 with MSAA @ x8.
The GPU Z screen shots show maximum temps recorded during the benchmark. The GPUZ windows up shows GPU1 info, the second window down displays GPU2 info.
BEFORE the stability test, here are the monitoring informations:
http://free0.hiboox.com/images/5009/...2f5300c91f.png
And DURING the benchmark, a screen shot of monitoring information (the Furmark was running in front of all the rest during stability testing, here it's running behind only for the screen shot, I used the Alt + tab function to switch windows)
http://free0.hiboox.com/images/5009/...fd7b3c6118.png
What's strange is... that my temps are not really higher than yours, but I don't use chilling, only watercooling... coolant temp is 27,7°C after 1h30 of Furemark load... yeah some degrees, but the difference is not huge. I though it would be a bigger difference.
[EDIT] hum sorry... you have overclocked your card... :) so yeah my results are without overclocking, with a single loop for WC CPU + GC.
