Introducing the "Cascade" waterblock design - Page 38

hmmm.....what about like...a year or two down the line.......and i've heard a few frightening tales from maze3 owners of their tops cracking...

No offence, but this has been asked at least 5 times in this thread alone. Go back and read Cathar's comments, you'll see exactly what the situation is.

Maze 3's use Lucite, a form of acrylic based plexiglass, for the tops of their blocks.

My blocks are using a pliable variant of polycarbonate which is substantially less prone to cracking under stresses. This was one of the things I made sure of. Polycarbonate based plastics are different to the acrylic based plastics such as Lucite, and much stronger. Look here for some of the differences and information about polycarbonate (Lexan) and acrylics (plexiglass). Polycarbonate is over 30x stronger than acrylic.

Some polycarbonate-based waterblock clear tops in the past were made using bullet-proof variants of polycarb, with the block makers thinking that the "tougher" the polycarb, the better, when in fact the reverse tends to be true when it comes to stress fracturing.

Well I hooked up this little bitty pump, which costs $9.95 at Bunnings. It's rated for 200LPH, and 53cm of pressure head, and draws 2.5W of power.

My test system consists of two Big Arse radiators in series, a sponge-type water filter, the Cascade block, two 1/2" sweeped copper elbows, and about 3m of tubing.

Due to the height differences in my test system, I had to use the Eheim 1250 to prime and bleed the system, and then swapped the pump intake over to the baby pump.

The resultant flow rate through the system was measured at 1.25lpm, which I actually thought was fairly impressive given the tiny size of the pump and the number of restrictions present that would not normally be in a tight water-cooling system. I'd estimate that the little pump would push maybe 1.5lpm in a less restrictive setup.

So how'd the Cascade go? Again, using the 2400MHz/1.85v test setting running BurnK7, the CPU rise over the water temperatures was an extra 4.0°C±0.5C°C over the Cascade system running at 10.5LPM.

Now the real margin of error might be more like ±1.5°C, so bear that in mind.

Still, running with the measured 4°C increase in CPU temperatures, these values are remarkably close to what the White Water sees as well but the Cascade is still cooling better than the White Water given these super-low flow rates, perhaps even handling the lower flow rates more gracefully than the White Water. I'd dearly love to get this independently verified because it throws a spanner into my assumptions of the performance of the block at lower flow rates. The Cascade really does perform quite well at low flow rates, but within my testing margins of error, I can't really be sure of what the full picture is, except to say that it's pretty close, but with the lead still being held by the Cascade.

Needless to say, the water also is significantly cooler than with the monster MD-30RZ adding heat to the system, so the actual CPU temperature increase over the MD-30RZ in relation to the ambient temperature is more like 3.0°C, which just goes to show again that bigger and stronger pumps aren't necessarily needed to yield decent results.

YAY!
a small pump that can still work
what size fitting are they?
at that price just by 2 put them in parallel or series.

Just received my block.

It's an amazing product, especially considering the low price.

Won't put it in till I get back from holidays.

Thankyou to Cathar for this great block at such a good price.

i'm pretty sure it hasn't been answered in this thread, but how much are the blocks? I feel that telling people in this thread the price is aceptable.

cathar : it seems some "team purchasing" (some people purchase a product to have good prices, and low cost for travel) on http://forum.presence-pc.com/forum2....trash=&subcat=

Are you "aware" of it ?

I read the AMDmb.com forum. Cathar really makes Australia proud!!

do u have a p4 mount kit for this block? im interested in this cascade stuff but i dunno if u have a p4 mount kit for it. also how well does it work on a ehiem 1048?

brembo · 5th July 2003, 10:29 AM

If you take a read through the thread, both questions ahve been answered, and one can be answered with pictures throughout the thread.

kuroneko · 5th July 2003, 12:02 PM

Cathar, sorry to trouble you but, what size allen key do you need to dissasemble the cascade waterblock. I didnt filter my water with a seive and now i have all sorts of nasties blocking my microchannels. (only one weeks usage).

strands of teflon tape and the blue green algae seem to be blocking the channels, anywho, wanna open it up and see whats going on. Its totally my fault, and if anybody is hesitant about buying one of these blocks because of this, dont be. Its a great wb.
