Global-WIN goes water cooling :)

Well, as long as they make the nice small solutions, they will close the gap between air and watercooling! but why they build this? :shrug:

Many budget HSF makers have been effectively shut-out of the market with the increasingly improved stock solutions being offered by AMD and Intel. Relatively few (in comparison to 4-5 years ago) have been able to offer significant performance gains with their HSF solutions over stock. The crown of air-cooling performance is basically held by Thermalright, with a number of other companies clustered closely behind, and there's extremely little left to gain.

Water-cooling is the "new hope" market for these guys now. Expect to see what was once the domain of higher-end enthusiasts to get encompassed by the rampaging Taiwanese hordes of budget water-cooling solutions. Soon enough they'll start fighting amongst each other, and developing more performance oriented solutions as they go. Prescott's heat will fuel the demand as well. We're just witnessing the first "marketing feeler's" of these companies at this point in time.

^ what he said.

Nothing will ever beat the simplicity and cost of good air cooling, but watercooling is starting to really enter the mainstream with products like these. Every time I see that thing though I think that that little green stem coming off of the pump/waterblock is a pen

It's so cute!

The copper/non-anodized aluminum block gives me the willies though.

Is water-cooling that mainstream?

If it's not, the enthusiast community won't touch that thing with a 10 foot(3.048M) pole.

One thing I did like about this small cooler, it the fact that they used the waterblock as pump impeller housing. No serious. Think of it. The impeller moves the water fast over the block, and this will give you the best turbulance possible.

Sure, it would mean a "whole new" impeller housing design, with fins and micro chanals.
I also don't like the idea of a big pump being held by the socket.

But the idea..... It's great!

Cathar, I guess you are the specialist in this area.

Can you tell me the minimal LPM needed to keep a CPU cold? Keeping the idea intact that the water will be moving at "high speed" due to the impeller, and that the water will be in longer contact with the fins, as an impellor does not move all the water that it has "captured", but will stay in there for 3 or 4 turns.

The last will make that the water will stay longer at the hot area, making it possible to take up all the heat there is, untill it reaches the same temerature as the cooling block.

Next problem will be that the heat needs to get out of the water, going via a radiator, so a second pump may/would be needed to keep a decent flow.

In my post "My steps into pump modding.. " I modded a small, 300l/h pump, original 0.7 m head, and after the mod a 1.3m head. It's small, 5w, silent and capable of pushing the water to a whole lot of restrictive stuff.

A pump like that should be able to fit in a custom made block.....

i know im going troll hunting but you realise that you dont want water stagnet over the hot spots you want exactly the oposite this issue has been beat to death so just do a search for "flow rate and race track" and you should find the pertanate(sp) thread

Both threads you should definitely read.

Cathar and j14ast, thanks for the links. Again a few hrs reading

...

few hrs later

Cathar's frist link is about what I mean, but with a channeled desighn for feeding the pump, and a housing of copper. His second try sure is nice, but he will lose half of pumping power as the inlet is not centerd.

Maybee with the additional pump mod (link 2), to get enough head from a small pump.

j14ast, I think you misreaded my idea. The water won't stay still at the hot-spot, it will be in turbulance. With loads of other waterblocks, the water takes on only a portion of the heat, one of the reasons why a bigger pump will do good. Not that much for the additional waterflow, but the increase of turbulance. With the impellor givving activly turbulance, where is not the need for a big pump......

Hmmmm... I guess I will make some drawings. Nice mod for a later date!

I like the idea of having a pump intergrated in the system
