Getting ready for the start of my machine shop class in a couple weeks.
Found a nice series of videos from MIT's Robotics Prototyping Machine Shop. http://techtv.mit.edu/collections/ehs-videos/videos

What do you think of all alum loops? Any problems?

Aluminum is a pretty good metal for heat transfer and a lot less expensive for prototyping. It's easy to find all aluminum heat exchangers too (like a transmission cooler for instance).

going to be making myself a copper/brass waterblock too soon. been talking with the owner of a local machine shop and making a few prototype designs. it will be a dual return block with square pins 5mm thick. i am making a few rough drafts on grid paper but I will probably be making a design in pro-e or solidworks later. all his machines are manual anyways so if I can make a good enough drawing, the cad drawing won't be nessasary. the best part is that it won't cost much more then the price of copper and brass since he told me it will be kind of a "project" which we can work on in his spare time. i am going to use my singer v8 (which is in the mail) for some rough dimentions, but my current proposed dimentions are 3"x3", 10mm thich bottom plate. 3"x3", 20mm top plate. this should include the space needed to mill pins and an open space in the top. more drawing to come (computer is down due to dead pump, no solidworks )!

Thanks CD!
Does corrosion occur only with the mix of copper and alum or would I have to be careful of adding other metals to the mix? (I'm thinking nozzles, which I believe are usually steel, no?)

corrosion will occur, but only in the long run. aluminum won't corrode in the short time you test the block. the final run should be made of copper. barbs are usually made of brass and then nickle or chrome plated.

Well, I'm thinking long run when I ask about alum. yeah, I'd like to prototype some designs and then make copper, but I'm also wondering about the feasiblity with a permanent all alum loop with commercial barbs (though I guess I could make my own alum barbs! given time )

A all aluminium loop would be fine, aluminium just has a lousy C/W as compared to copper.

This is for cold plate thickness and materials but its also pretty good run down on heat transfers.. Cold Plate Materials and Thickness-Bill Adams

yeah, copper has about twice the heat transfer coefficient compared to aluminum. but aluminum is fine really... if you need a rad for all aluminum loops... check out koolance if you dont want to mess around with car radiators. should do great for less critical loops. i think aluminum should do fine on graphics cards, and even more so on "peripheral" parts as MOSFETs chipsets, RAM, etc.

About aluminum barbs just use a tubing beader (Parker Tool) on the actual tube. That's how they do it in on airplanes and yachts. Not an inexpensive tool...and then there are Ferrules (available in aluminum) http://www.discounthydraulichose.com...rules_s/88.htm that slip over the hose once it is slipped over the beaded aluminum tube and then crimped using yet another not inexpensive tool...http://www.discounthydraulichose.com/product_p/855.htm

So for about $500 you are all tooled up to make a nice hydraulic connection that could withstand several hundred PSI

Koolance makes these pipe fittings

http://www.koolance.com/water-coolin...product_id=835





Don't even have to flare the end, just slip the female end on, then the ferrule and then tighten down on the "swiviling" G1/4 end and I am assuming by swiviling, they mean it is a rotary. One of two places I can buy that ATM, PPC...which I am not buying from again...and Koolance, which wants over $50 to ship 10 of those to me.


Also, maybe you're interested in how your block performs compared to a standard and you want more info on what it's dong besides load temp, idle temps read off the mobo info. I mean, if you're making a "prototype" out of aluminum, maybe you might want info like how your block affects flow, the temp of the water going into and out of the block....becaus how do you know what to change based on load and idle temps?

I got myself 4 BP temp probs, a fan contorller with 4 temperture indicators that can go from -9c to ...whatever (forgot...but remember -9 because most of them do not read below 0c, but this one does), a couple quick disconnect fittings to make it easy to swap out CPU blocks and a flow meter




That cost me about $270ish ( I already have all the T fittings needed for the temp probs) and will allow me to see how restrictive my block is compared to some commercial blocks I have, 4 different temp readings around my cpu loop and the ability to swap cpu blocks with little fuss. Can go with a much less expensive flowmeter I am sure. The one in pic cost me $165 at mcmaster-carr. There is a 5GPM, 3" scale on ebay right now for $20. A little less accurate, but still pretty useful. There are some other tools I can get, but it starts to become much more expensive and I decided these were all the testing tools I really needed. Anyone think of more?
