Loading ...ACDC

This may become a problem… there is a blatenant and excellent reason for the use of DC fans in a PC. An AC fan (in this case with an induction motor) produces huge amounts of magnetic flux. Although this sounds cool, thanks to ‘Back To The Future’, it spells disaster for a PC. If i ever wanted to knacker a computer it would be with a magnet.
This only affects DC motors the instant that they are turned on.
At this point i’m really asking for suggestions. I think that housing the motor in as much metal as i can, and sitting it near the PSU (the only other AC component) may be the best way of handling things. If anyone can think of anything better, let me know.
But this did lead me onto an idea for my PSU and optical drive. This is useing a ‘wind tunnel’ kind of like the Antec P180 and P190 have at the base, and haveing a single 120mm fan pushing air front to back, keeping it separete from the other air stream.

The problem is, if i can make an working balanced water loop, how do i remove the heat?
Well not wanting to re invent the wheel i will use a fan. But i will try and be slightly origonal.
The first thing i did was decide on an efficient air path. the front panel will almost be compltely be replaced for a grill and filter. This will be (obviously) the intake (i’m gonna have to sort the PSU out separatly) air is then pulled evenly to the back of the case, where it is then extracted out to a duct on the side.
This duct is where the magic happens (or the horrible fire where the water leaks onto the fan). The first departure from from tradition is the use of a centrifugal fan. This is massivly powerful (and borrowed from a domestic tower fan, £15 from Argos, bargin). This sucks in air top and bottom, which is by the VRMs and the buisness end of the GPU.
The air is then passed through a ‘Cross talk attenuator’ (CTA) to absorb sound from the fan. Finally all the air is passed over my radiator. which will be 300mm long and about 100mm thick.

Ok, i’ll start with the water cooling. The principle that i am trying to use is a header system. I use a large diameter pipe (a 22mm copper) to supply water around the PC.
From this i ‘T’ off reducing the size each time. with 3 items needed (GPU, CPU and Northbridge) I will reduce to 15mm and then 10mm. Each of the feeds to waterblocks will be in 10mm.
The return to the radiator is reversed, first gets a 10mm retuern then 15mm and finally 22mm. The principal is call a reverse return, and ensurese that each branch get an equal amount of water or self balances.
This should enable the water to come directly from the radiator to each component, not looped. so each component gets an even amount of water at the same temperature.

Loading ...Water Cooling Sucks
a531016
After a while of looking at water cooling systems, i decided that i could do better. At the moment i have started to butcher the side panel for my PC, and will shortly be adding a fan and radiator.
I have also decided i would try and make a modular mod for the molex and ATA power distribution in my PC. This may work. It may not (more than likely).
As i come up with ideas, make progress, or need advise, i’ll note it here.
Wish me luck…
