My homebrew block #3

[iandh]

I sold my last homebrew block to Cyberdruid, it was a great performer but I was bored, so off it went. This was the result of my saturday night:

Channels are 0.800" x 0.800", 0.200" deep at the egdes & 0.075" deep at center. Base thickness is 0.060", step is 0.875" x 0.875". Top is delrin, mounting bracket is 7075 Aluminum with black enamel finish. Impingement is roughly equivalent to Fuzion with 5.5mm nozzle.

The design isn't perfect, just a freehand shakedown run.

Offset base??

[iandh]

The base is centered with an offset outlet, similar to a TDX.

[perfection]

oh okay, explains it then, looking forward to results

[Nanometer]

dude, hurry up! looks really nice

[Garrett]

Nice, sexy black :)
Can't wait for the results :)

[septim]

looks good and promising...

[csjsi]

Nice skills :up:

[RockfordFosgate]

I like this block good job ;)

[bf2142lol]

lol you have the exact same thread in overclock.net:p: I'm viewing both:rolleyes:

[Pub_Randy**]

interesting channel layout/shape will be interested to see how it performs :up:

[disruptfam]

waits for performance results :)

[Kunaak]

I am actually quite impressed with that build.
very clean solid design.

[nikhsub1]

Nice! Finally someone is doing it right! What people will soon realize is that the only cooling point that matters is the point above the step (approx. 23mm ^2). The rest of the block is just there for ease of mounting. Good job iandh!

[Martinm210]

Perfect as usual...got more CNC drool on the floor over here...:D

[71 (Bryan)]

wow, wish i had a cnc machine.
when can we get some temps?

[iandh]

Thanks all, I'll see if I can get some rough numbers tonight, unfortunately the only chip I have right now is an E4300 ES that I won from ebay for $63. :p:

Well, there is one little screw-up but I covered it pretty good. :D

For some reason I've been deathly afraid of slitting saws for my whole machining career. I've finally realized you just have to crank that sucker up and go balls out on thin passes and they glide right through.

Yeah the conversation we had in that one thread kinda got me to thinking. This is more of a proof of concept than anything... The jet size/location, channel depth, etc. probably can be improved but this is a start. I actually considered doing the same profile (.8x.8 w/dip in the center) with diamond pins but I decided to try slots first. I think diamond pins in this configuration may actually work better but it remains to be seen, since the slots will probably will act structurally to apply more pressure to the core. :confused:

That's what testing is for... too bad i don't have, oh $100,000 to develop with CFD. :p:

I've been searching your pics trying to find the little screw-up but I can't seem to find it :p: :D
Care to tell?
Got some rough numbers already?

[headala]

I likey. I don't what it is about machined delrin and copper that makes me drool every time I see it.

IMHO, it would look even more sexy with some socket cap bolts.

I agree with everything just said.

Excellent job!

[NaeKuh]

wow iandh very nice as usually. :D

[ladderman]

Great workmanship, looking forward to some test results:up:

[leo_bsb]

great work :clap:, now get that block wet and give us some results! :up:

[Meatpuppet]

I really like the oval inlet channel. I don't know if it will make much of a difference when all is said and done, but it is a good idea nonetheless.

[systemviper]

WOW< some day, I'd love to play like that, it would be Nirvana. Love the custom work and great idea! Top Shelf,,,

[Boogerlad]

isn't the 23mm^2 step only good for intel ihs? making it not so good for amd and other cpus?

[iandh]

isn't the 23mm^2 step only good for intel ihs? making it not so good for amd and other cpus?

I don't really think that the step would necessarily hurt performance on an AMD or other intel chips that don't use this IHS design, because the step is still larger than the actual die under the IHS.


So it looks like my $63 E4300 ES from ebay is possibly a little gem (for an early batch chip). I've got it bootable and game stable at 3.4ghz @ 1.425v with almost no effort. I haven't run prime long enough to find out how stable it really is though.

Here's the setup:

I'll try to get some load/water delta numbers for you guys tonight or tomorrow.

edit: Well, it was failing Orthos without system hang in about 30 seconds, I increased the vcore to 1.4375 and now have been running about 15 minutes. My estimated water temperature is 21C (2C over room temp), Idle is 24-25C, and load is running between 43-46C. I'll pick up some temp probes at work tomorrow and get some real measurements.

[leo_bsb]

what case is that? Nice final build.

[evil-98]

looks even better mounted, what software do you use?

[iandh]

what case is that? Nice final build.

It's a somewhat heavily modified Lian Li PC-A05B, with an MCR320 shoehorned into the bottom.

I actually use the shop floor programming on our Centroid CNC controller, but for drawings I use a Mac program called Graphite. We just got a nifty new program that is called Shark FX though, we will be switching to that probably.
