Silenx G80 waterblock

It looks like SilenX has the first G80 waterblock. I will let the pictures do the talking:

dunno what others think but imo that thing is ugly as sin

Here are my views:

(copied from another thread)

Who ever is considering this block, say stop to yourself.

The good thing about the block: it shows excellent milling quality of whatever machine was used.

Now, there are several VERY bad things about this block:

One thing can be said for sure: if this block is made out of aluminium and copper (unless the silver part would be silver (which I doubt) or nickel plated copper (why have just parts nickel plated?)), there will definitely be galvanic corrosion. Yes the alu is anodized, this will go away with time though... There is no stopping it (yes, additives can put it off, but it is only a question of time). The block will definitely corrode around the area where there is a transition between the ALU and copper, causing a leak = water on your G80 GPU. I'm sure no one wants that.

Next, there are several things we can deduct upon looking at the design.

The block will definitely be a flow killer. Thin channels, and several U turns. Another thing that is interesting is the orientation of the fins above the core - by the looks, the water just flows above (i.e. there is no direct link). A more logical approach would have been to have the fins rotated 90 degrees - much less restriction and better performance.

The channels should be made wider, with less U turns.

Lastly, the rubber o-ring is just way too complicated. Why not make the block a little bigger, and have an o-ring with straight edges?

Overall, I'm not impressed.

All I see is one beautiful piece of machining ;)

The flow path looks quite generous, actually.

does the job:toast:

DAMN,Thats a nice peice of billet!!!!!! :rockout:

[spectre440]

would you look at the size of that thing?
i mean, what's next waterblocks the size of volkswagens?

[giorgos th.]

seems pretty nice and it cools the mem chips also..

[Munkul]

very nice. there should be plenty of flow rate, only if youre running 1/2 in pipes or bigger will you notice reduced flow. i think it looks awesome!;)

I think its too heavy =/

[Munkul]

theres no way that weighs more than the stock heatsink, probabl not as much.
