I dont think I got enough plastic...

:D

Gonna make some designs today and see how they work out. I have plenty of stuff to experiment with.

UHMW seems to be very slick, and not as scratch resistant as I thought. If I push hard, I can dig into it with my fingernail and make a mark, but not really remove material. This means it will be almost too easy to machine :D


You wanna buy a bar of my stuff? I have three and they are huge. (you can obviously tell I bought too much in the pics :D)

how much would you sell half a length for?

$5 + shipping sound reasonable?

EDIT: shipping will be about $6 I think, so $11 shipped.

hey that sounds great!

PM or email me at chrisandvelvet@hotmail.com to let me know how to pay for it... I can do paypal...

This Delrin stuff is great to machine.

Possibly a bit too soft though.

EDIT: HOLY CRAP!!! I thought my camera was in 640x480.... Grrrr. I'll chage the pics later. For now, you will have to deal with it. 56kers better click off this page now :cry:

This stuff is a bit soft, but I managed to get the design working.

Time for some updates:

Worked on the NB block today and managed to finish it up completely.

And I started the GPU block today, milling/filing out the edge so it can still use the shim.

I managed to make a mess out of it, the screw that stops the drill press from going down farther (the stop I think) got loose and I gradually started milling deeper and deeper. I managed to catch it before I went through the copper, so it is okay. Lesson learned: dont try to mill stuff with a drill press unless it is plastic :mad:

Better (and smaller) pics of the block.

Going to finish the 9800pro block within the week, so dont worry:)
Enjoy!

As for the flow pattern, these pics are pretty easy to follow:

wow thats nice! any idea how it performs? i was thinking of making something similar as my slk800 heatsink is soo good, better then the commercail block i bought, but it would be even better with water, but i think i saw your thread first, thank you for the idea :D

btw were the fins on the heatsink soldered to the base? when my h/s arrives (im not cutting up my slk800!!) im half hoping they are, then i can use a soldering iron to remove them one by one without the mess so i would just have to cut the others down to size - then the other fins can be used in my silver gpu block to inc surface area, something i think it needs. if the h/s is just one part, it would probably perform better, not by much though. acctually ive thought about cutting out the center bit below the fins and inserting a square of silver, thats enough of my ideas though, ive got a thread that ill try to share them in, think youve already seen it :D
if you have any more spare of that plastic i may be interested in buying some, will have a look on ebay first though as shipping from US to UK would cost a bit, that matieal isnt sold in the UK though, so i might just use copper , something for me to think about in my thread anyway.
one thing ive also been thinking about is how to get a good flow through all of the fins, as the outer ones wont get much, maybe solder a fin cut in half across the other fins blocking the top half which would also give faster flow on the input side, or slower flow on the output side.
very interested in how these perform, will you be making any more?

The fins are not soldered to the base, they are carved out of a solid block in a process called skivving. It is kind of like whittling wood. This is much better for heat transfer. Also, I will probably make a CPU block and I have a ton of this stuff left over. I could probably ship it to you, but I would have to find out what shipping to the UK is. It will probably perform as well or better than any commercial GPU or northbridge block to date.

The square of silver thing may be difficult to do and will probably not yield a significant performance gain.

Update: This is a little OT, but I finally finished my LCD. I think I am going to mout it externally, probably because I have it on a 6 ft. printer cable :D

how hard was it to mill the delrin? could it be done relatively easily with a dremel on a lower speed without melting the plastic?

nice lcd killernoodle, ive got the mx212 (blue 2 line one :D)

i havent used derlin before, but when cutting the accrilic thats on the front of my cheap case (to make the bezel for my mx212) it melted very easly with anything. i expect derlin and similar plastics will melt easly so cut i slowley with low rpm. for plastics imo a cordless /normal drill will be better (using the dremel bits) as the rpm is much lower.

It is not delrin, it is UHMW Polypropyline (sp?). It is very soft, incredibly easy to machine, doesnt really melt at all, but I wouldnt cut it with a dremel. Drill press is great for accuracy.

BTW, I finished my GPU WB tonite, I am leak testing now. My camera wasnt charged, so I didnt get any pics of construction, but I'll get some of the finished product sometime tomorrow. Nite Nite :D

How did you mount the barbs for your radeon block? looking forward to pictures.

GRRR, it wont let me upload the last two... :mad:

How well does that RTV sealant work, as UHMW polypropylene is self-lubricating and non-adhesive?

Those are looking great man! I would like to see a few more pictures of the gpu block. looks kinda similar to mine ;)


whats the dimentions of those bars?

-edit- Dude, you should make a cpu block just like that chipset block. I bet itll perform really well.


Jon

Yeah, it wont lemme upload any more pics. Apparently, I have consumed all of my FTP bandwidth for the month (?). Anyways, the RTV seems to seal excellently and turns into an O-Ring kinda when it is put on thickly. Plus, it looks nice and clean and is easy to clean up. The UHMW is great for the tops of blocks. You almost dont even need to put any kind of RTV on it because it molds to the shape of the base with enough pressure. I love this stuff!

I was thinking about making a CPU block withthe same kind of design, maybe with three barbs and a jet nozzle. I have plenty of stuff left :D

How should I test these blocks? I dont have anything to compare it to except for the stock ATI cooler and the vantec copper chipset cooler on the NB. Maybe I should just put them on and not test them :D I know they work well already. I would have to buy/make another block to compare them to.

You can use this http://www.h4x.co.uk/upload.php free uploader for hosting your pics if you want. nice looking blocks. how thick is that plastic?

It is .75" thick, so it is fairly thick stuff.

As for the blocks, I learned that the 9800pro core is not recessed behind the shim like the 9700pro, so I dont need the ring around the base. Therefore, I will have to re-do the base of the waterblock to prevent the torque of the extra thick tubes from chipping the core... Tbird style :D

Anyways, I am ordering another heatsink tonight (I might make a CPU block too). Sorry about not posting pics, but I also got my DFI Infinity NF2 today, so prepare for some crazy ass overclocks and stuff.
