Pin style block (almost)

[joemac]

I was browsing through my garage last night and came across one of my first professionally made water block. This block was never meant to be offered for sale but instead was used to gather test data. I was Originally only going to show this to a few people in this forum but decided instead to share with all. The block is 2 x 2 x 2. The pins inside are 1 7/8 inches in height 1/16 diameter. The base plate on the bottom is 0.0393701 inch or 1 mm thick. If you have not figured it out it is ONE SOLID PIECE.

Hehe looks like that block reviewed by [H]. Wonder how that happened...

I assume it was milled?

[winewood]

How thick is the base? What kind of tooling made those round pins?

looks like a die-cast job.... right?


the pins are way way too long..... almost long enough to be a proper heatsink.....(for air)

LOL Yes it does - actually it was one of its cousins that got out and ran amuck . The thing was done using a EDM machine- total time per block on the machine – 45 minutes. Defiantly not meant for sale they were created to test the pin style block ability to cool even under extreme low flow. Actually very cool stuff to test.

and the conclusion to said test was?????

It was almost 2" wide.

With out being too technical, as the flow rate decreased the change in performance in a pin style block suffered less. So much so that this pin style block could operate using ¼ tubing, an 80 GPH MAX pump and still provide enough heat transfer for what we use it here- CPU cooling. The thing is this – Pin style block work really well if you want to water cool using a small pump, they work well with an exposed core CPU, and seem untouchable in performance using a T.E.C or integrated heat sink CPU.
Now as you may know nothing good comes free. The main draw back is that pin blocks take longer to make which = more machine time = higher cost = less people willing to make and sell them as all this adds up to less profit.


Note:
This testing was done using the spec’s giving earlier

This was done to accommodate the test CPU:

oh, but that's the best part! making pin blocks yourself for next to nothing, using a cheap pump, and knowing that even if you dont do a perfect job your block is still better than 95% of top of the line commercial WBs this sounds like a mastercard slogan...

Having all the tools to do it with priceless….


Hey maxim when are you going to post pictures of your Rig ?

[#Rotor]

95%...... I dono about that.....1 % is what I'm after...

[maxim]

hey, i was just trying to be careful and not to start any wars here all i have now is a block that gets me about a 20deg cpu-air gradient with my system, so it's by no means a monster. but wait till the latest block is ready, the one that actually has concave pins and stuff, and then i'll start talking smack! (hopefully )

joemac, i'll post pics when it looks like a RIG this is what im sitting on right now while im in the process of making all the blocks... slowly, but surelly...

[joemac]

What kind of mother board it that ?

[maxim]

Shuttle AN35N. and let me tell you, it's a POS. i always bought abit before, but after reading all these good reviews on the shuttle i decided that maybe they are good now or something. NO! the bios is crap and it's very unstable. let me put it in numbers: i can only run about 167x11.0=1837mhz out of my 1700+ chip with Corsair XMS (CPUburn stable). in an ABIT NF7-S that my friend has, it ran 210x10.5=2205 like a trooper. im getting that board soon, i need to break at least 2Ghz if im watercooling!

[joemac]

“I-will” was very OC friendly before don’t know about now. I will also be shopping for a new board soon. I used shuttle before, they are good for normal pc use. So how is your block working? I thought about making the die area over the CPU 1 MM thick on my current block but I opted not to since the days of open core CPU are numbered (if not already over).
