I'm sorry for taking so much time to update you, I'm working on a water cooled PSU, I fried mine , since I only had one and it took me a few days to get a new one I had no PC for the last few days.

Please also take a look at the thread I'm starting on GPU water blocks, link here
.
Well about the blocks, I had 4 finished, one was already sold, one is for myself and the other 2, well I'll have to sell them to people from brazil (really sorry) because I pay $10 for each international money wire I receive, so even if I sold the 2 together I would still loose $10 out of $30. For the 2nd batch, using my merchant account at paysystems.com I'll wait until I sell like 10 blocks, to tell them to wire the money for me, so I only loose $1 for each block because of that damn international wire fee. I can't sell those 2 and leave the money in the US because I need it to buy material to make the 2nd batch. That sucks, I know but the 2nd batch should not take soo long to be ready, than I'll have like 20 blocks ready to sell.

I found a solution for precise (1C error) temp measurement, I got myself 4 of those $10 digital thermometers used to measure fever, they have some very small 50k thermistors in them, these are great because they can fit between the water block and the CPU if taken out of their metallic protection and they can also be used under water if you don't remove the metal casing from the thermometer. They're also good quality. So I have 4 50k thermistors and I'll be putting together something like this: http://www.benchtest.com/gp_Temp5.html, take a look at gp_temp1 for more details on how it works. So in a couple of days max I'll give you very precise C/W numbers, I'll be measuring water temp, radiator fan intake temp, and CPU, also this time I will include the whole 23 watts of my pump in the calculations, I only put 6W in my last calculations because I read the value from my 500L/h pump box instead of the 1200L/h I'm using. That should give us even better C/W numbers!

@Marvin: Thank you, for everything. Something tells me you already have one working on your PC

@V12|V12: Thanks! You have a point about the looks/performance thing, they will be sold as seen on the pics, I think they look pretty good and it doesn't take me so much time to polish all sides of them, just the bottom. All of them are all copper, except for the hose fittings that are brass, the top is painted copper. I'm very very sorry but you'll have to wait for the 2nd batch, as I explained in the beginning of this post I cannot afford to loose $10 out of $30, that would be selling them for $10 each

.

@MadDogMe: The tops are made of copper, they're covered with 2 layers of base paint, 2 layers of grey paint and something I forgot the name in english on top to protect the painting.

@2old_honda: The base is 49x56 and the upper part is 61x56, as I said before the measurements may vary on the sides by 1 or even 2mm because, well I already explained earlier in this thread and it and you probably don't even want to know why

Thank you
