Check this homemade WB out

you are still not telling me anything i don't know.

the water temp will increase as the system runs for longer until it becomes stable. with decent case airflow this block could have worked with minor adjustments as the air temp will be lower than the water temp

EDIT: Seriously do you think that someone would think that their properties would change?

Ok... here is the problem that we see.
1. For you to get that kind of delta you would need a great fan on that cpu block, because of the difference in mediums.

As vapor said, the noise coming from that 1 fan is better adjusted @ the rad.

If you dont understand difference of mediums after being said 4 times, then i give up.. actually i already give up, i am just now going to defend martin, vapor, and shazza.

What are you thinking in terms of fabrication costs for materials, tooling, and machining? Is you intent to sell or are you just having fun?

That seems like a fairly hefty mass of copper that'll be pretty expensive on fabrication. I recall making some more standard sized blocks...I think I managed to mill out about 2 to 3 different bases.
Martin

Lemme remind these guys exactly who you are... and what i did to make you retire from milling:

Four!...ok I'm not worthy... Only two for me, one is 4 and the other 16 months. That's enough work as it is.....


Well....fabrication on the blocks is finally complete. I probably have 100 hours into these, so needless to say these will be two of a kind..

Here are some assembly pics:

















I put all 5 TEC's in just for testing sake, they were a 91watt variety, and I found that one TEC running at 12volts draws at most 63watts and starts dropping off as the two blocks heat up. So, hooking up three of them to the meanwell under water should draw right around 190 watts or so.

Anyhow, it's probably not worth testing in a loop until the meanwell gets here, I have a couple of smaller fabrication projects to hop over to and get done.

You guys have no idea who martin is do you?
I did a lot of sponsoring for him b4 the vendors started sponsoring.
He has done a lot of tests, and he's also spent a lot of his own out of pocket money..

This is why a lot of people respect martin.

Contact wasn't great. Looking at low-90s/high-80s for initial temps at 22c water temps on the remount. I'll let this run awhile.

EDIT: for the record, the fan is really loud at 100%. Anybody running 120-140mm fans at comparable noise levels on a 2+ fan radiator will see extremely low water-to-air deltas already.

Thanks for the test... and yeah we were talking about how the noise is better placed @ the radiator.
