Storm G7 Proto

[nikhsub1]

Heh, looks like Cathar got her done! I'm sure he'll post around soon, but check it out at OCAU:

I hate the way that they wont accept hotmail, gmail or yahoo on OCAU.

Means that I cant register as im a roving internet user and dont have a ISP email address.

Can you steal a few pics plz nikhsub

Hope you don't mind stew... you did post it on OCAU

[moonlightcheese]

very nice. hopefully we will see a refined gfx block from cathar after he finishes this. we've reached the threshold of water block performance for CPUs. now hopefully he can do the same for the GPU. ^_^

What seems to be the difference other than the dual port connection cut?

[nikhsub1]

almost 3x more jets... oring around intlet.. lots of changes

[leejsmith]

The number of jets , size of jets and spacing between them.
the swiftech storm has 35 jets this g7 has over 110 jets almost in the same area.

Wow... where do I sign up? Looks good to me. I second the notion for the better GFX block.

[ChongL]

very nice

[Frambosie]

man, it just keeps getting better!

[cartmanea]

I think you would definitely need an inline filter with this bad boy or the smallest gunk would clog it up.

[magg]

Isn't having that many jets going to affect performance? The amount of water going through stays the same, but has more places to go through, so it would seem to me that the pressure would be less and flow would slow down a bit?

Please correct me if I'm wrong. Regardless, I'd pick one up anyways...top notch blocks. Too bad they cost your first born child.

[Holst]

I think that the effect or more smaller nossles is better then fewer bigger ones.

Cathar can probably explain the specifics of why.

[racinjimy]

and I just bought a Storm..........................

[Nanobot]

Looks a lot less restrictive than the G4 !

The basplate pins look really low profile

[chinkgai]

im in for two!!!

[chinkgai]

i wish...rofl

[Bloody_Sorcerer]

that... is... so... sexy... holy crap. cathar, you never cease to amaze.

[cartmanea]

Ok, that's it, I need to make a block. I thought of an internal design like the Swiftech 600(2) about a year and a half ago and look where that got me....

I guess I need to go to the metal shop on campus and do whatever is needed to get certified to use there equipment

What seems to be the difference other than the dual port connection cut?

For starters, it's a G7, rather than a G4/G5.

G1 = 1 jet
G2 = 7 jets
G3 = 19 jets
G4 = 35-37 jets (implemented G4 has 35 jets)
G5 = 55-61 jets (implemented G5 has 59 jets)
G6 = 85-91 jets
G7 = 117-127 jets (implemented G7 has 117 jets)
G8 = 155-169 jets (could only machine on aerospace quality equipment)

As for the design improvements over the original base Storm design specification:

• Increased jet inlet plenum area to lower pressure drop (thicker top-plate enables a more voluminous plenum so water can reach all jet inlets with minimal restriction - visible to eye))
• Ported jet intakes to lower pressure drop (jet intakes are now all ellipse radiused using a custom manufactured tool - visible to eye)
• Tweaked jet lengths to lower pressure drop (jet lengths are shorter - internal + external mod, middle plate is significantly thinner too)
• Tweaked jet outlets to lower pressure drop (each jet outlet is chamfered around the outside of the jet tube to offer less restriction for flow exiting the cup structure - barely visible to eye)
• Multiple flow path channels to outlet to both decrease pressure drop, and more evenly distribute jet flow and total base-plate cooling (self-explanatory and very visible to eye)
• Base-plate bracing to boost structural strength for high-pressure CPU mounting (the 12 little posts that surround the jet area brace the base-plate and also serve as additional water turbulation for water outwash cooling effect over base-plate outside of main jetted area)
• Improved top-plate strength for higher pressure mounting capability (just a thicker top-plate, which is offset by thinner middle plate)
• Middle-plate bracing to improve jet/cup alignment when used with high-pressure pumps (additional consequence of the middle plate posts - reduces middle plate flexing meaning jets stay better focused with respect to their cup counterparts under very high pressure operation - meaning >>10psi)
• Improved O-ring specifications to minimise assembly based warping (smaller O-rings and slightly wider O-ring groove dimensions, thereby meaning less clamping pressure required to seal minimising the amount of pressure that gets applied to the base-plate effectively eliminating base-plate flex on assembly)
• Additional O-ring seal between inlet to middle plate plenum and outlet (this one's for the armchair waterblock critics - I never deemed it necessary but people often griped about the design needing one even though it doesn't, so I put it there to keep them happy anyway - may as well)
• Improved cup/wall ratios for higher performance (minor ratio adjustments - added base-plate strength too)
• Improved jet turbulators for higher performance (two prototypes being tested)
• Improved base-plate characteristics for higher performance (adjusted base-plate thickness suitable for G7+silver)
• Improved jet/cup ratios for higher performance (tweaked ratio adjustment)
• Improved low-flow performance without sacrificing high-flow performance (micro-jetted efficiencies are much higher even with lower flow rates - also a consequence of turbulator modifications and jet/cup ratio adjustments)
• Improved small bare-die performance (down to 7x7mm CPU dies) without sacrificing IHS performance. (simulated and tested adjustments to attempt to cover the widest possible variety of CPU types)

Sounds like a lot of good engineering! THUMBS UP!

[Cathar]

Just added a picture for idea of scale. Shown is an Australian 10c, which is the exact same size as a US quarter (25c).

The middle plate shown in the picture above is actually a faulty prototype and the jets on it aren't quite right, so if you see differences between that plate and the other middle plate pics, that's why.

when will you start producing these so we can buy them also will there be a massive waiting time again and a rough price on them is.....
