You must be somewhat anxious.....I know I am. Like a kid a christmas exept your not sure if Santa's really gonna show up. If things work out for you within the next 3 or 4 months partialy because the timing would work out perfectly for me . WCing is ripped out of my current rig right now whilst I upgrade.I have all in hand exceptin a block- new rack mount case, 2xD4s...brass ones even, dual Thermochill 120.1s, I have a 5/8 od mandrel bender in hand and I'm going to do much of the main tubing in 1/2 id Cu (except where i can't squeese it or it needs to move) The "P2" would complete it nicely, as I was having no luck at all scanning forums and eBay for a used Cascade and wouldn't touch an RBX or similar if it were free. The whine of my 60mm 6k rpm SK700 air cooler is a constant reminder to get to work on it. Nevermind that I had to derate my oc to run it on air. So wishing you the best here...albiet somewhat selfishly. And also looking forward to how some of the manufactures look in the aftermath of the "storm".

Why doesn't anyone ever try overvolting the MCP 600? jlrii: The approximate difference between the WW and the Cascade is 1C... Why not just grab the WW? Is that 1C really important enough to make you keep that whiny (and much warmer) HSF?

Cathar, I am seriuosy glad you figured it out finally!
Benefits are quite phenomenal there. Massive increase in coolants velocity with increased pressure combined with substantially higher water to copper surface area. There's one more problem here. It's 3D design of a block using pressure force and velocity increase effects. All I can say is that there's a compromise to be struck here between an amount of coolan't molecules being in contact with copper in any given time, restrictiveness and spot cooling technology. I got inspired by foamed graphite cooling tech Keep digging m8! You are so close (or maybe you are there already???) Last edited by Jabo; 02-19-2005 at 02:08 PM. |

Yeah, 60% more flow in an actual system isn't that great. How much improvement does the D4 allow?

mcp600 12.0v 0.98A 11.8W 5.8LPM 16.0v 1.41A 22.6W 8.0LPM which is a 38% improvement.... the D4 gave: 12V approx 19W 7.5LPM 16V approx 24W 10.5LPM http://forums.overclockers.com.au/sh...5&pagenumber=7 why would you go to the effort of overvolting an mcp600 (seperate psu, separate control circuit, plus an unknown effect on the life etc...) when a stock D4 delievers virtually the same performance without the hassle. the attraction of overvolting the D4 is iwaki performance cheaper and more compact..... |

An MCP600 oc'ed to 15-16V gives US-spec Iwaki MD15-R sort of performance. A 15VDC power-pack is a pretty cheap thing, and the MCP600 + 15VDC powerpack would be considerably less than the Iwaki MD15-R.
Not that overclocking of DC pumps is a terribly good idea if you care about warranty or pump life-span (I don't and I don't try to RMA a product that I broke - I accept the consequences of my actions), I still wouldn't recommend running the MCP600 at more than 15V as it may not reliably start up above that voltage. I use 2 x D4's in series for my testing, attached to a lab bench PSU where I can run the voltage from 5V (Eheim 1046 sort of performance) right up to 16V (US-Spec Iwaki MD-40RZ sort of performance). I tell ya, the 2 x D4's in series at 16V provide plenty of push, hitting around 19PSI or so if you want to try to stop them from flowing. Excellent cheap pumping power.

A Laing D4 at 16V dead-heads at around 6.8mH2O. 2 in series = 13.6mH2O 13.6 x 1.42 ~= 19.3PSI Here's my plots of my measurement for the Laing D4's PQ curve at 12v and 16v: here. |

Damn the whiny noise! The teal would be approximately representative of the Mag 3, correct? Oh well. Are the results of those experiments (the ones with the higher flow along with the higher temperature offering a higher overclock) applicable to the WW as well, or is it simply a Cascade thing?

I live in the us, and I am considering buying an Iwaki md20-30rz pump. Since you have had experience with the new danger den pumps, would you reccomend them over the iwaki pumps?

Well I should be picking up the Storm/G4 later today. Been testing the Storm/G3 against the Cascade SS, establishing a base-line and verifying results. On further testing the G3 has retained its ~1C lead over the SS, using a Barton AthlonXP 2800+ @ 2500MHz/1.95v running BurnK7, and these results apply to both the on-die diode, and external monitoring. Performance vs pumping pressure tests show that at lower pumping pressures (~Eheim 1048) that the G3 still holds a slim lead over the SS, which slowly grows as the pumping pressure is increased.
With the G4 I don't anticipate any major gains - slightly more than a 0.5C improvement at the standard testing conditions if reality matches theory. It may work out a little better than that as the G3's implementation did have a flaw that I tried to work around, but am uncertain as to how successful I was in doing so. |

Does the heat that the Lian D4 puts into the water justify its noise, and lifespan over the iwaki? Also, which Iwaki model would you reccomend?

At approx. what gpm & head rates do you see the 1C improvement over the Cascade SS?

Which Iwaki model? If you live in a 50Hz power country, the MD20-RZ seems the best fit. If you live in a 60Hz power country, then the MD15-R for a moderate one-size-fits-all type of pump, or the MD20-R for low-moderate restriction setups, or the MD20-RZ for moderate-high restriction setups. |

I'd have to agree about the whining noise. Just post the sound file... It speaks for itself.

Well here's a piccy of a somewhat dirty prototype G4. Sides don't quite align properly, but since people always ask for pictures....
Sorry, no "internal" shots... |

needs more "i will kick your ass" stickers across the individual platess to seal it up (think Danger Den meets Schwartzenneggar)

Looks sexy nuff for me. What made you choose aluminum? (or is that some kind of plastic, delrin perhaps?)
