So all these swiftech heatsinks with fans (and giant copper baseplates) do pretty well for overclocked machines with just a nice fan on top. What if you took the fan off of the top, and boxed in the heatsink helisoid (sp?) pins with copper plates, and forced water through it? (ie. see my terrible ms paint idea below)

Water absorbs heat so much more efficiently than air that all that extra surface area would be unnecessary and the huge volume of it all would only serve create dead spots where there was little to no circulation. You want the coldest water directed at the CPU core and then to leave as soon as possible. Also, the thing would weight a ton filled with water.

Well that specific block would have problems because the points come out at angles and hang over the sides. That would make boxing it in difficult. Otherwise it would probably be better than nothing assuming you could keep the water flowing pretty fast through the block, especially since the poles would cause some sort of pressure drop.

Agreed...

Your sig looks to be about 3 to 4 times too big. Just a fyi.

seems to me like an MWC6002 only with more restriction..and aluminum screws instead of copper pins.

It is based on ideas entirely different from the MCW600x block

How is it different? Water flows through pins.. only this time they are wider, in higher quantity with less spacing in between.. which lowers flow. At the same time they are aluminum which may cause issues with mixed-metals causing corrosion.

ummmmmm
i'm thinking 3 barb deal with that - 1 in top shootin water directly into center

a left and right barb of box for outlets

that should not restrict no flow

just a thought

but copper and alu in the same block would be a loop kiler...

This is pretty much on. Part of the problem with a design would be the size and the unecessary surface area. You also want a much smaller baseplate. Yes, the MCW6000/6002 is basically a pin design enclosed in a block, but the water moves in a spiral pattern to a single outlet. This design works fairly well, but isn't anything spectacular. The biggest selling points for these blocks is the low pressure drop, low cost, and leakproof copper design while maintaining acceptable performance.

Generally, while two outlet barbs does help with flow restriction, the difference is very little. Not enough to make up for how much of a pain in the but two outlets are for plumbing.

The idea for a pin-based block is alright, and has been tried with moderate success, but you should look at designs for blocks like the Cascade. Really, water is an entirely different ballgame than air.

soong pretty much covered what i was going to say

As stated by everyone else, water cooling a little bit different than air cooling. But don't worry, at least this idea doesn't come up as much as "I've got the greatest and most original idea: computer in a mini fridge!". I was waiting to see it when opening up this thread.

I have heard of people putting copper stock heatsinks in acyrlic casings and using it as a water block though. Haven't heard much about it tho, and I'd kinda like to see some pics. Oh well.

Check out Hoot's "water sink" from a few years ago.

As I recall, it was a promising prototype and it performed fairly well for its day, but could not quite keep up Cathar's White Water. Had the jet impingement block not been developed, blocks like Hoot's might have become king of the hill.
