Re: "Nazca" - Waterblock Concept
 

When you apply physics, it makes no sense. If the IHS is thermal epoxied/pasted to the core, the heat should radiate from the core out. Not from the edge towards the core.

Re: "Nazca" - Waterblock Concept
 

I don't like his numbers, though I believe his analysis.

Re: "Nazca" - Waterblock Concept
 

artical 1284 has some floors but the heat transfer is easy.

Google biot number. Increse the cooler performance your going to change the biot number.

Re: "Nazca" - Waterblock Concept
 

bobo, thank you for the biot number reference but I was refering to page three of artical 1284 and the inconsistency of the die temp vs. center temp relationship.

Look at the "IHS Temp Pattern - Die Simulator" table.

Could be poor calibration or a data entry error. Maybe the sensors are just inaccurate.
It would be nice if he had provided some attempted explanation.
What little(very little) experince I have had working in my college's chemisty lab tells me he owes at least a note addressing the discrepancy.

I did not mean to hijack the thread, I am sorry.

Re: "Nazca" - Waterblock Concept
 

No biggy. This hasn't been discussed in detail anywhere else as far as I've seen. It's strange how much myth there is circulating around concerning the thermal load differences between IHS and non-IHS processors.

The block will be finished on Tuesday.

Re: "Nazca" - Waterblock Concept
 

Well, the block is finished. I fixed the inlet, fused the top and middle plates, and thoroughly cleaned the base using white vinegar and a toothbrush. I'm still trying to figure out how to go about testing it though.

Re: "Nazca" - Waterblock Concept
 

Time to try mounting everything together.

Re: "Nazca" - Waterblock Concept
 

wow, good work to get it done!

Re: "Nazca" - Waterblock Concept
 

It looks like it was well made. Good job!

Re: "Nazca" - Waterblock Concept
 

Jaydee is going to be kind enough to test the block for me against several other modern blocks. Which is good because I have a wickedly time-consuming PCB to get to work on.

Re: "Nazca" - Waterblock Concept
 

Fan controller?

Re: "Nazca" - Waterblock Concept
 

Nope, it's a plug-bus. Or rather one half mounts on the edge of the motherboard tray, the other to the case.
You connect the motherboard, pump, fans, and lights to the tray half with standard cable extensions, then connect the power supply, fan controller, switches, etcetera to the case half. It makes/disconnects all of the connections at the same time (including SATA which will be a seperate part that won't require a PCB).
The end effect is I can remove or install the whole motherboard tray without having to unplug a single cable. As a safe-guard two small solenoids will prevent the tray from being removed while the machine is turned on.

This is my first original PCB design and I've been working on it and learning how to design/make them since September of last year.

Re: "Nazca" - Waterblock Concept
 

Ah! I can see that coming in handy!

Re: "Nazca" - Waterblock Concept
 

Got the block today. Will be getting the bench tuned up and start testing things this weekend.

Re: "Nazca" - Waterblock Concept
 

Yaaaaaaaaaay. Let the anticipation commence.

Re: "Nazca" - Waterblock Concept
 

Nazca Vs. AquaXtreme MP1-CPU.

The Nazca is a very good block for a DIY'er. It flows very well to. I managed 8LPM for the Nazca and only 6.5LPM for the MP1-CPU block.

At .5LPM the MP1 was 3C cooler at 6LPM about 1.5C cooler.

Tomorrow I will add a few more blocks to the mix.

Re: "Nazca" - Waterblock Concept
 

not bad at all for a DIY water block, congrate

Re: "Nazca" - Waterblock Concept
 

Hooray! Not bad for a first-timer and that's kind of inline with what I was expecting.
I REALLY appreciate your help jaydee. If there's any artwork, CAD work, etc. you would like done let me know.

Re: "Nazca" - Waterblock Concept
 

If you are not in to big a hurry to get the block back I will take a dP reading aswell. I just need a meter to read the FoxBoro dP meter. Ordering today.

Also have a MP-05 SP on the bench right now. Will add to the chart when done.

Re: "Nazca" - Waterblock Concept
 

No hurry. I have alot of other stuff I can work on before I get around to putting my loop together.

Re: "Nazca" - Waterblock Concept
 

MP-05 Pro added. The MP-05 Pro is little more restrictive but better at lower flow rates. This is the one wiht the multiple hole jet. I managed 5.8LPM with this block.

Re: "Nazca" - Waterblock Concept
 

Nice results so far. Are you going to do more tests with other blocks or do you have any other tests you've done on your test bench we can compare it to?

Re: "Nazca" - Waterblock Concept
 

I have AquaXtreme IceFloe and White Water LE to run through as well. Takes me about 8 hours to run a block through. Have to wait until next weekend until I have that much time. Hopefully I can get the dP meter going as well.

Re: "Nazca" - Waterblock Concept
 

Wow, thats a lot. Is that 8 hours supervised or is it something you can setup and come back to every few hours?

Re: "Nazca" - Waterblock Concept
 

I usually stay in the same room as I don't have any safe guards setup in case something fails. After each flow rate adjustment I let it run for a couple hours to let equilibrium set in and take a reading.

Re: "Nazca" - Waterblock Concept
 

I think that is not just "not bad at all for a DIY", it is excellent performance. Inbetween
TDX and Whitewater and can be improved on.

He's still missing the middle jets and I think he can get better flow rates by opening the outlets

Re: "Nazca" - Waterblock Concept
 

very nice work what kind of milling machine are you using?....i'm planning on buying a mini lathe hope it will work for what i want to do..

Re: "Nazca" - Waterblock Concept
 

I remade the nozzle plate before assembling the block and it includes the 4 nozzles in the very center.
http://www.captainslug.com/modding/mk6_9999992.jpg
I'm wondering what kind of affect on performance changing the channels in the base to straight ones would have.
I used a huge 1973 3-axis Bridgeport manual mill. This block would have been a million time easier and faster to make using CNC, but I do not currently have affordable access to that kind of equipment.

Re: "Nazca" - Waterblock Concept
 

man that's really nice work but where are the blue leds? lol....yea cnc machines are expensive... im getting one of these i think http://www.mini-lathe.com/Mini_mill/Main/mini-mill.htm but i already have a drill press...maybe i should jsut get a better x y vice ....its a mini miller/lathe kidna thing looks pretty good... who knows

Re: "Nazca" - Waterblock Concept
 

i hear about you guys lapping the block how do you do that? i just put some sand paper on a flat peice of aluminum stock and put my sand paper acording to how smooth i wanted it... is that what you do or what?
