Heatkiller waterblocks produce a huge number of blocks with great build quality. If you are struggling to find specific blocks for motherboard's or GPU's I would check to see if either EKWB's or Heatkiller do them, as between them they do pretty much blocks for everything and if they don't do them, its likely the waterblock your looking for doesn't exist.

A certain Heatkiller block caught my eye the other day, it was a DIY RAM/MOFSET block which can be cut down to size for any card. Allowing you to cool parts of the GPU which is often neglected if you only use universal blocks and no heatsinks.

Now obviously a bit of airflow or some heatsinks is enoguh to solve any VRM or RAM heat issues on your GPU or motherboard if you even have any, so this post is NOT about its performance! I myself cant comment on its performance since i haven't tried them but i cant imagine it being substandard.

Don't be put off by the block not covering the whole copper base, since it has to be cut to size, you obviously cant make it cover the whole base. There also isn't any need to, due to coppers wonderfully high thermal conductivity. These block's don't cost much and a new copper base can be bought for 10 euro form the manufacturer, if you want to upgrade components and are afraid your cut base wont fit.

For me the most appealing feature is how unique it looks. Unfortunately these blocks use their own fittings which connects to their own 'push in' tubing. I don't like the idea of anything on my loop being push in without a barb involved, sounds far too sketchy. I was sold on this product until i read that it wasn't 1/4g threads. I thought if this could take standard fittings i could use a 90 degree adapter and loop my tubing from the VRM's and into the universal blocks much the same way you would do it from your motherboard VRM's to your CPU or RAM block. Unfortunately this is not the case. The final thing that put me off was the idea that you might need several of these on a GPU depending on the GPU and that there was no mention of the design having high flow. Multiple high restriction blocks with tiny fittings could cause serious problems if you have a weak pump in your loop.

I do love the idea behind these blocks. Here is a picture of the block used on a gtx660 with their own universal core block.

What do you guys think?

If this block took standard fittings, I would be ordering right now!

Many full cover blocks look nice but i think this is a refreshing change. In terms of function some full cover blocks don't actively cool VRM's (take XSPC's 7950 block), but they don't really need active cooling, so once again im going to say reasons behind getting these blocks are NOT to do with performance gains but rather customizing your loop more and of course for aesthetic reasons.
 
That's interesting. Do you know how the plastic block is connected to the copper, and what the dimensions are?

The biggest stumbling block I've found with diy is the O ring connection between copper and acetal, as cutting the channel is a pita without a CNC mill. If they've solved that in clever fashion I'm up for cutting the copper base to fit my motherboard.

If the block is 13mm wide or so, you can drill it to 11.2 and tap for g1/4". I'm going to see what google has to say.

edit: Found a lot of shops and two different sizes for this "microSW-X". I can't seem to find an official website, best guess is *oops*. Photo of the base plate suggests there are countersunk screws in contact with whatever you're cooling.

On a closely related note - anyone have an idea for connecting a copper plate to plastic? Preferably more reversible than epoxy.

edit2: no competitors, right..

Plenty of info on their website shop but i cant link. It answers all your questions!

The removable copper base is screwed to the blocks copper base via 3 screws i believe, making it super easy to remove/replace and most importantly cut.
 
All I've been able to find (on what I think is their main shop) is:
The HEATKILLER® microSW-X DIY is a universal cooler for graphic card voltage regulators. It allows water-cooling of voltage regulators for graphic cards, even if no matched cooler is on offer. Do so, the bottom plate may be cut to the desired dimensions and fitted with appropriate mounting holes by the user.

Base measurements of the bottom plate are 100 x 40 mm, and the cooler ships with a set of screws and nuts.

Use of thermal compound is recommend, the thermal compound is not included.

Current best guess is that the base is actually just a flat piece of copper with three holes in it. Anyone able to drill holes in the base to fit to a graphics card could also drill those holes, so I'm not sure I see the benefit. Have you found a photo of the inside of the block?
 
I haven't seen any photo's of the inside yet. The heatkiller is the name of the brand of the waterblock's, i think the company is called Watercool. I would have probably used adhesive thermal compound to stick these to the GPU rather than make screw holes to screw them in.

I think the idea is nice but comes with a few too many complications. Maybe if i get board i will give this a go.
 
Really wish ocuk would stock heatkiller blocks and also monster rads, would save having to look elsewhere
 
I did see this a few weeks back, I'd argue they aren't truly universal, as on some cards you may have caps etc... in the way of getting to a mounting hole. A great idea anyhow, could open up a world of possibilites for those with non-supported blocks :)

OcUK have stocked heatkiller in the past and from what I can make out there really isn't any reason why they couldn't stock them again (unlike phobya etc... who are owned by OcUK's parent companies rival in Germany).

I'd also like to see them stock heatkiller again, especially GPU blocks.

I think that's one of the sexiest things I have even seen, if only they made a plexi version /drool.

As for restriction you will probably find that not all of the flow goes through that tubes it will split a small amount off from the main flow path, like EK's full cover blocks where the VRM channel has a bypass allowing water to carry on round the block.

EDIT:

Apologies for the MS paint but this is what I'm trying to describe:

yeah In the way they have it on the 660 block there would be no change in restriction, but if i could have it my way i would put my own 90 degree fittings with 3/8 ID tubing, coming out of the VRM block and bending back to a 90 degree fitting attached to a universal block. That IMO would be amazing. Im so sold on this idea, that i might even look through the whole of EK and heatkiller's sites for a motherboard block to match the VRM's for my card, would have to use adhesive thermal compound to mount though.
