Cooling experiment....

post #1 of 22
Thread Starter 
I had this post on the water cool section but I think it should be here instead.

This is the test...Total ~ $180

*$25 old computer from local residence
*$35 Using a ac like system with condencer, evap, and pump.
*$75-80 for 5gal of EDM-30 or EDM-500 insulating fluid.
*$45 for a new home made acrylic case.

I am told that EDM-30 has a freezing point of -10f and the flash point is not relavent because this fluid is used in EDM machines.

Testing starts next month.

That sort of liquid is what I was talking about! Nice find!

Thanks. still trying to make sure this fluid will not gell too much when I put in the coil. If it does then I may have to go with just a large amp hsf instead of the ac unit. In theory the temps should still be way lower than air.

I am going to submerge the board in the fluid. there will be no air for condensation to form and the acrylic case will not sweat, just like cold water reef tanks. The fluid acts as an insulator and a cooler, I will not have to seel the electrical components from one another while they are submerged. I still need to read more but I think the major problems are the fluid not reacting like I was informed, and the compressor not working properly, everything els is attention to details. Of course I could also be completely off, but that is what the tests are for. Learning from mistakes.

Is EDM-30 similar to Fluorinert solutions like 3M's FC-43?

it is much like it. the viscocity may be different. I checked out the 3M and found that the pour point is much lower which is nice but what I have chosen so far was originally used for shock cutting and electrical etching, the product line is rated from 150 amps to 400 amps, the fluid I chose is rated at 150 and the pour point is quoted at -10c. I may chose to go with the 3M but need to do more research.

Do you mean a boiling point of -10*F? Freezing point would make that completely useless.
It goes to eleven

the pour point is much like freezing point, the fluid may crystalize around the coil but will circulate around the mobo. the boiling point is well above 200f and with the cooler that temp would never come. as I said before, I am also still researching fluids, there are other alternatives like.......http://products3.3m.com/catalog/us/e...er/output_html

My bad - I read over the first post quickly and thought you were trying to replace the liquid in the mini-ac unit
