Way 12: Optimal heat transfer and accurate installation.
The wires are well laid out and cleaned the body lower the volume by about 3db.
The zone will not heat blows air through the chassis, which will reduce the power and means of fan speed.

Heat pipes:
If the thermo-carrying elements of heat pipes used, their work begins with 22°C, and the temperature of the CPU at the moment 22°C+0,041*(CPU power watts), which at 125 Watt will start cooling the CPU 27°C.
You can remove the thermal resistance using Wood's alloy with a melting point of 60-100°C, in fact become welded processor to the cooler, but thus raising the efficiency of heat transfer.
Google-search studies on the effect of temperature on memory and HDD gave the following result - the best temperature range of 36-45 C, and the memory is better behaved at temperatures of 24-26, 32-36 C. It should be noted that some manufacturers at temperatures above 45C in certain types of loads are catastrophically degraded performance, it is necessary to bear in mind.

The successful arrangement of elements heat exchanger, SCYTHE GRAND KAMA CROSS
Zalman 9500 AT - copper instead of aluminum. This heat exchanger can be cooled with water, it does not give a galvanic pair, as in the case of aluminum-copper. Also, the properties of copper for aluminum heat much better.
Change water at water-cooler:
90% Ethylene glycol + 10% Water
Boiling Point :285°F; 140°C
Freezing Point: -20°F; -29°C
60% Ethylene glycol + 40% Water
Boiling Point : 230°F; 110°C
Freezing Point: -55°F; -48°C
What you should know in addition to these figures? You should not drink it - it is poison))). And the smell as if leaks from skunks. It is easy to get, look for freezing liquids in auto parts stores.

Important! Look at the degree of toxicity of the liquid.
Calculate the maximum permissible concentration of harmful substances by evaporation.
It is possible to use various synthetic oils with high flashpoint. Pay attention to the dielectric properties of fluids and their physical properties. Seal multilayer chips (video card) and the processor in the socket installed. Dielectric fluid disrupt contact between the processor and socket.

Mineral oil, "Crystal Plus 70T":
It is very unlikely that removal of the fans will cause a fire. However, it is very likely that it will cause your system to rapidly overheat, crash regularly and eventually give up all together.
The fans are there for a reason.
You will need to replace your system with a silent one such as a media centre PC. However, I warn you that, unless you also replace your hard drive with an SSD, it most certainly will not be silent.
No it won't cause a fire. It will, however, cause your computer to stop working within about a minute. If you want a silent system, get new, silent fans. There are many quite good fans around.
In fact, multiple slow moving fans are quieter than one or two overworked ones.
I have found these sites to be a great help in building a silent PC:
