I see that you have actually designed something rather than waiting until one of us figures out how to calculate it.

I am very happy about this development. Now you can try it out and determine by experiment if it works or not !

If it works, I can make my own : )

I got sucked in by life for a moment. I can calculate the whole thing for oil using data I found online, the only problem is still convective heat transfer coefficient for air. "If you know the nusselt number," well, I don't. Putting the whole thing in aluminium is good for cooling perhaps but it ta...

In your link to engineeringtoolbox.com (another post) I browsed around and eventually I found the following: The overall heat transfer coefficient for a wall or heat exchanger can be calculated as: 1 / U A = 1 / h1 A1 + dxw / k A + 1 / h2 A2 (1) where U = the overall heat transfer coefficient (W/m2K...

Also, if thickness matters, you might be able to get away with a plate that is thinner than the aquarium glass. A metal plate can be a lot thinner and have the same strength, right? It seems like changing the back side into finned metal could benefit heat-transfer by a combination of effects. I don'...

Even if the material doesn't matter, which I'll believe in an instant, can't you get a bigger surface area / volume ratio by finning the metal plates? It sounds a lot easier to get a finned metal plate than a finned glass plate.

Edit: Scratched original post because I didn't do my homework. So isn't it possible to fully passively cool by using a larger aquarium and about 40 liters of mineral oil ? That sounds expensive but doable. You could probably do some tricks to either increase surface area (passive radiator?) or you c...

I'll simply use it for what it can do. Almost everything I want to do is optional, not a need. I think most software that I run can take advantage of four cores. According to bit-tech.net, Intel Core 2 Quad Q6600 Overclocked to 3.6 GHz gives you the best performance / cost. I think they didn't facto...

Lava-lamp PC?

I would definitely go for submerged if I could make my aquarium-pc into a lava-lamp pc (have blobs moving around the aquarium). Then the sheer awesomeness would blow any and all disadvantages out of the mineral oil.

Does a quad-core give me more performance / $ or less?

Cost-efficient builds?

Hi I'm looking for ideas for a new build. The problem is, I have no clue what I need because I tend to adapt what I run to my computer instead of my computer to what I need to run. My budget range is 200$ - 1000$ I don't really care about how much I spend so long as I get a good deal. There's only o...
