I opened this because I thought you posted a pic of the babe you sent to customs to pick up the wbs
??

He took the picture down, we are waiting for one with "improved white balance"

Hey les could you please add the MD20rlt the one more commonly available (or I guess I should say cheaper) here in the states? If you are looking at this to get the info

http://www.iwakipumps.jp/products_e/...f/md_w2003.pdf

I am pretty sure it would be the MD20-R(M)-N

Added Iwaki MD-20R(M)-N (60Hz)

On a side note, anyone ever try running the Iwaki MDs undervolted? Say, to running extremely quietly? Think it would be a problem?

Also, I have the high head, Z-type MD-20 (on 60Hz). The way my tubing is, I would be more convenient to instead of having the extake nozzle pointing upward, have it pointing sideways. Would it be a problem if I unbolted the front part (I believe that's the technical term) and rotating it 90 degrees?

Sorry for the thread hack. ;) Looking forward to getting a G4 soon.

what is the attraction in undervolting a high head pump ?

the pump head can be rotated to any position

my Iwaki MD-30RZ is a 100v model, running it on a AC variable transformer
i have varied the voltage from ~80 to ~120v, no real change in noise, very minor change in flow....so son't bother

Yes, that will work. The outlet can be turned to aid in shortening lines & avoiding bends. A good thing to do.

Does not the pump run noticably hotter if you run a 100v pump motor @ 120v?

I guess I don't understand why you wouldn't have purchased a US115v motor version.

How much flow rate increase did you gain by running it at 120v, and what are the specs of a MD30 that's a 100v model?

Some people walk only because they saw someone else do it. :D


Hey!!! That belongs in my sig!!! j/k

specs are not affected by the voltage... i imagine brucoman bought it on ebay, where 100V ones come up fairly regularly... (as do 115 and 220v ones ftm)

So whats next Cathar? Any new designs in the works?

What about a GPU design? A version of the Storm for the GPU would be great! I know I'd want one.

GPU blocks just don't seem to improve as fast as CPU blocks do.

A set of TEC water-chiller block plans are with the machinists at present. Depending on its success in that arena the basic design could be adapted to a fairly effective and cheap to make GPU block, and as a moderately effective CPU block. Design is more targetted towards cooling larger areas effectively, rather than the hot-spot focus designs that I've been concentrating on of late.

AWWWW SWEET!!!

I've been hoping for something different and better than the NV-68 block I'm using right now...

Any chance it can even cover the memory along with the GPU? I know that's highly unlikely, but I figure it can't hurt to ask...

I can probably figure out something for the memory if not...

Perfect, exactly what I was looking for, thanks. Thanks to everyone else as well.

Ooooh, a GPU block from Cathar inc.! :drool:

If targetted toward cooling larger areas at modest cost.......how would this design compare with a Storm blocks jets for cooling?

Or how would the new design compare with the Fusion, which is one of the best at the moment for GPU cooling? (A known commodity)

I'd be happy to pay more for the focused extreme cooling of the jets as used in the Storm adapted into a GPU block design myself if you offered such for the GPU.

Edit: Disregard

Whoa! Let's not get too carried away okay? I'm not particularly fond of GPU blocks due to them being so fiddly and non-standard. The stuff I make costs more, I appreciate that, but I always try to make up for it by making the designs as universal and forwards-compatible as I am able to, so maximum use is obtained out of them.

What is my first focus in the low-cost TEC chiller thing. The GPU idea is a distant possibility, and def. not something to get hopeful about any earlier than 6 months from now, if even then. It's just a back-burner thing at present.
