It is for VRM's.. water generally doesn't flow over this area though I'm happy to see Eddy post below that it does now.
Nevertheless, when you get into voltage adjustments on the card, the VRMs can get really really hot.
Bojamijams does have a point though. Unisinks are really useful.. I've used my same MCW-60 on 3 different videocards and have only spend $50 on heatsinks for all three together... Thats a ton of money saved... And I have never found an increase in over clocks by directing a fan on my heatsink than just letting the normal airflow over it, that heatsink is HUGE.
Hi.
Does it cover this VDDC chip / that area?

Thanks.
Oooh yeah that would be good to know
Looks like it does.
You kind of line up the block to the PCB by starting at the bottom left corner where it goes from that ~45 degree edge back to straight parallel with the bottom of the card. At the corner you can see there is an integrated standoff and that definitely lines up with the bottom left mount hole around the 5870's chip.
Going up from there, you can pretty much assume that the block is going to have line up with most of the mounting holes in the PCB to ensure it attaches correctly. So that first 'scoop' on the upper left looks to be for avoiding that square rectifier under the second Crossfire connector at the top edge of the board, not to mention to clear the Crossfire connector itself.
In any case, it looks to me like it will cover the component and area you are asking about.
I know this might sound incredibly stupid or genius. Couldn't you just use a Dremel and cut out the area on the stock heatsink that is over the GPU and put a MCW60 on it?
That's for sure.
I've stopped making my sinks (maybe or maybe not permanently) for that very reason.
You and Eddy and everyone else who still offer full cover cooling solutions have brass balls for doing so IMO, and the worst part of it is that it's something the market really NEEDS. I commend you all.
It's a nightmare... 2-3 different reference revisions, and at least twice as many AIB partner revisions. Insanity.
I wish it was still like when I did my first 8800GT sinks, where you could get a good solid 6 months market viability from a single design.
These GPU manu's sure as hell aren't making life easy for the aftermarket business.
Wouldn't the "unisink" idea make even more sense then in such a changing market? Cheaper and less risky for the manufacturer and cheaper and modifiable to the end user.
And if unisink is copyrighted then what shall we call that part?
Does anyone know if an acetal topped Maze4 will work with a 5850? I know it fitted on the 4870, I don't want to jump for a 5850 and then have to buy a new block too.
+1 on that. I can see a FC block making more sense for the voltmodders out there seeing Eddy is getting the VRMs under water now too. I also see where they can be nice on show rigs, as they can look a little nicer than unisinks.
For most people though, the unisinks are better. They don't have to be made out of copper, so they are cheaper and shouldn't need a huge retooling in the factory to update to the ever changing reference designs. :)
Dtek heatsinks are called unisinks . . .
For me, my gt200 is a heatsink :shrug:
Soo, i call everything heatsink and not unisink that is a brand from dtek
Great job, Eddy :up:
Would love to see the VRM temps get under control....my Koolance FC blocks do not cool the VRMs very well at all. Stock volts they are around 100*C at load -- when voltmodded they would hit 130-140*C!! I believe these blocks don't use water on the VRMs directly, it's almost like a heat-pipe type setup. I'll either go with sinks in the future on my VRMs or with a FC block that actually does use water on the VRM part of the block.
My two 5870s are on their way, so I'll be in line to pick up two of your blocks as well, Eddy. Can't wait!
and pwm thermal pads as well I guess? :up:
Like promised. Its Tuesday and pictures of the block are here:

The nickel plated version gonna look SICK :D
