Wow. Very cool the ''pre applied thermal pads'' for the HD5970. Nice block Gabe! And a replacement backplate, shorter than the stock one, delivered into the bundle, very good idea.

Do you know when (and where) this will be available for Europe?

A question about the GPUs cooling for the 5970: what is the benefit of the pin matrix? Compared with other solutions on the market for HD5970, what is the benefit of this design?

I consider to go back on a HD5970 if Fermi is not as good as I expect it. I had one (5970) with another waterblock, but swapped it for GTX295 sli because of stability issues. So... I think that you bundle for HD5970 looks very good. And some more details would be welcome

Best regards,
Cyril

The pin matrix lowers the block thermal resistance at the GPU level, in other words: it means better temps at any flow rates. One of the critical benefits is the ability to run at very low flow and still get outstanding performance (like the apogee XT for example). I see for example that you are interested in silent operations. I demonstrated a silent (guesstimate at ~ 24 dBA) system at the XS party with a setup similar to yours (quad sli), and temps under furmark remained impressively low given the load.

no full cover block for the 5850 huh? Damn

Look very sexy, great work gabe.

[ohms]

The clear version is -AWESOME-
You guys need to put that into production!

Always great work as usual Gabe.

[washu9]

VERY nice blocks.
Really makes me wanna jump to the ATI bandwagon.

[irenedakota]

no full cover block for the 5850 huh? Damn

Um, yes there is. In fact, I got it yesterday

The HD5870 and HD5850 FC block are the same (You just switch 3 stand offs around)

[exe163]

How well does the the unisink cool? I am planning to get one but worry about voltage regulator overheat.

[EvilClocker]

Gabe, you have any result on the VRM cooling on the 5970 block ?

Thank you Gabe for your answer Yes it could be very interesting for me to lower the pump speed to decrease the noise level. For the moment my D5 are running @ Speed # 3, and #4 if running some benchmarks with OCed CPU and GPU.

But for my nest rig, I'll try to configure a silent watercooling system, with highest power possible @ lowest noise level. So yes i'ts very interesting. I'm a hifi and home theater fan and the next rig will be dedicated for this. If I can achieve the low noise level target, the pc will be placed in my listening room.

Another question for you: what about the pressure, I mean you are talking about low flow rate, but do we need some higher pressure to compensate lower flow rate? In other words: small tubing, pump with high pressure and low flow rate? Or possible to use for example D5 and 7/16'' ID tubing?

Last question: do you have some recommendations for a European reseller in particular? For purchasing from Luxembourg. MP if you prefer

Best regards,
Cyril

[WaterFlex]

Very good blocks, Gabe

[Mech0z]

Very nice with the heatsinks for MCW60, just wonder if there is any on the way for 5750/70 as I cant decide if 5850 is overkill for my use :X

[Boulard83]

Hummmm, im very tempted by the MCW60 and the heatsink ... cheap and modular lil thing.

[eth0s]

@Gabe: those new blocks look great. I also see that you changed the top on the MCW60 to acetal instead of aluminum, which is also nice. The aluminum top with copper blocks on the old 8800GTX Steath gpu blocks, and the old Apogee GTX, was a huge mistake. I'm still disappointed about buying those two. But hey I still love you Gabe, because your MCR320 rad is still awesome, and it is still keeping things cool nearly 4 years after I bought it. The MCR320 is by far the best $50 I ever spent (and I'm not young, and I've spent $50 on a lot of fun stuff ). Also loving my micro-res's ver.'s 1 & 2. They're still working great too after many years of faithful service. But aluminum and copper? What were you thinking?

Another question for you: what about the pressure, I mean you are talking about low flow rate, but do we need some higher pressure to compensate lower flow rate? In other words: small tubing, pump with high pressure and low flow rate? Or possible to use for example D5 and 7/16'' ID tubing?

@Scaniris: I think you are misunderstanding the relationship between head pressure and flow rate. Head pressure is generated by the pump. Generally speaking, higher head pressure will lead to higher flow rate. Lower head pressure will lead to lower flow rate. When Gabe mentions a low flow rate system, he probably means that you would be using a low head pressure pump, which is set to operate quietly. The other reason you would have a low flow rate system is if you are trying to use only one pump, in order to save on noise, in a very large loop with lots of restriction (pressure drop) which is thus causing low flow rate. To answer your question simply, you do not "compensate" for low flow with higher pressure, low flow is the result of low pressure. And presumably, the low pressure has been a conscious choice on the part of the system builder with the idea of reducing pump noise.

How well does the the unisink cool? I am planning to get one but worry about voltage regulator overheat.

Being an air-cooled solution, cooling of the VRM's is proportional to the amount of air flow, and of course overclocking/overvolting. At stock settings, passive is sufficient to keep the VRM temps within specs. When overclocked/overvolted, ventilation is necessary.

Gabe, you have any result on the VRM cooling on the 5970 block ?

no hard data, but the combination of liquid cooling with the high-perf back-plate contributing to cool-off the board should yield outstanding results. We also made sure to cool everything... please refer to http://www.xtremesystems.org/forums/...8&postcount=35, in particular items 6 and 7

For reference, the MCR Drive that I used for the Demo had an MCP355 with PWM, running at 1400 rpm's instead of 4500 rpms. The unit was totaly silent. Temps were great even whith substantial GPU overclock.

Resellers: please contact stephanie@bacata.net for European resellers.

I haven't worked on the 5700 series, sorry, I can't answer.

for the Unisinks, should the fins be going the other direction for a better airflow path? im think of a sidewindow fan, otherwise you will want high intake pressure on the case to force air out of the pci slots. which isnt a bad thing, just a little harder to control i think.

I woulds just stick a 120mm somewhere under the GPU.

if your running a multi gpu setup, there might not be any room between them, or not enough for a fan atlesat. and gabe did mention that there needs to be airflow on these when OCing, so im trying to understand if this fin orientation was best

[Boulard83]

For multible GPU youl could put the Fan at the Back of the 2 GPU blowing air on both card ending out of the case if you left the dual PCIE slot oponed for air flow.

[Baenwort]

It is because with the 4870x2 Caldera HS that had the fins in the direction you asked for they had people like myself asking for the other direction so we could mount a fan at the end of the board and blow the hot air out the exhaust slots. This also helps those of us without a side fan or any desire for one to properly cool the card as I couldn't fit a fan between the top of the card and the side of the case. This way if you have no side fan you can easily cool the card by either puting a fan at the end suspended from the top of your rig or just lay one on top of the HS and it would blow down all the cooling fins.

If you have a side fan just get some spacers and put a 80mm fan blowing down into the fin channels redirecting your cool case air into the channels.

[Boulard83]

IM really thinking about trying this on my HD5870. The card is kinda loud after 40% fan speed ...

lol im glad that at one point they had it the other way and switched it due to popular demand. i do see both options as valid, and just curious.
