well i got the 2 waterpumps last night, becketts pond pumps, we will see how they do. i know i had one running for the past five years in my pond with no problems.
this is my second system, the first system was cooled by just the cold side radiator by a ductwork that pulled the cold air in my case from it with one 92mm panaflo case fan.
i was running a sp-94 at the time so i had some major heat in my case. im running the promey now so this is all to cool the video card and NB and SB and ram and everything else.
it all works so much better when its really cold.
my first system is still up and running at my nephews, i gave it to him. the one thing it wasnt was quiet. but it will maintain a case temps of 7C.
this system should be very quiet. im using pretty much a few different areas of expertise that ive been involved with over the past several years.
sound systems. i know how to build some pretty awesome tuned port boxes. im a cabinet maker by trade and build custom furniture.
the box will really absorb the sound of the compressor and fans and will have great airflow also.
if you yell in a open room with no furniture it is loud. now yell in a room with furniture, your not nearly as loud.
now yell into a room full of foam padding. we cant hear you.
here are some simple facts that may be helpful to you all also in building anything.
sound bounces off of things to travel further.
certain shapes and materials disrupt the length of its travel.
if you yell at someone upwind they are less likely to hear you then if they were downwind.
a big can and a small can sitting side by side
they both have an object that projects the same sound within them.
they each sound different. so does each speaker box, seashell, and shape.
by these simple theories i should have have a very cold and very silent computer. i wish it was all that simple as far as sound measurement and cubic displacement vs. airflow. but i should be pretty darn close to a simple low freq hum. way less then a fridge.
