That's basically what I purchased - https://www.amazon.com/gp/product/B00JLV4BWC/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1
And the thermal trigger - https://www.amazon.com/gp/product/B078PY8L9F/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
I am going to address this concern, in great detail, because I believe it'll be important when another person attempts to try and do this and for that random person who Googles if this has been done before -- they will get a plethora of information versus nothing.
Forwarning: The Titanic was known as "The Unsinkable Ship" so ... I'll try to remain humble and just tell you why I think it's not likely to happen.
Overheating: Incredibly unlikely to happen.
Eletrical shock: Incredibly unlikely to happen.
TLDR:
I have implemented multiple layers of protection for my PC, including Glass Cloth Tape, Silicone Rubber Gasket Sheet, and Molded Polyurethane, to ensure high electrical and heat insulation. The Glass Cloth Tape is designed for 600-volt dry locations and has excellent dielectric insulation properties and high heat resistance, suitable for electrical insulation in industries such as aerospace and military. The Silicone Rubber Gasket Sheet has a high dielectric strength and a continuous operating temperature of +260°C and an intermittent temperature of +260°C, making it ideal for electrical insulation applications in motors and transformers. Molded Polyurethane has a high dielectric strength, resistance to electrical breakdown, and a continuous operating temperature of up to 150°C, making it a popular choice for electrical and heat insulation applications.
Expanded research on thermal and eletrical protections:
First, before any of this happens, I am going to use specialized equipment, a Digital Thermocouple Thermometer (think of it as a multipoint thermometer), to measure various spots of the GPU backplate at fullload for a few hours. This is to ensure the temps the "LCD package" are good stables temps. The computer has been on for literal 24 hours and I touched, with my bare hands, the backplate just a short while ago... it's cold to the touch and colder feeling than ambient room temperature. The GPU is currently 26C (78.8F). I haven't done any gaming today just Reddit and Twitch but these temps are normal for that computer.
Cooling:
There are 7x intake fans blowing air into the case (3x 140mm, 4x 120mm)
CPU water cooled with iCUE H150i ELITE CAPELLIX XT Liquid CPU Cooler
The GPU has 3x 120MM fans blowing cool air on to the GPU
Exhuast:
There are 3x 120mm set to exhaust from the top of the case through the radiator
There is 1x 140mm set to exhaust from the back of the computer
3x 120mm exhaust blowers that sit on top of the computer's radiator externally of the case to expel hot air faster than stock speeds of "natural progression of heat"
The computer is inside of a custom noise dampening cabinet that has the following...
Several layers of sound dampening and deading materials made of fire resistant materials
Fresh "natural flowing" air intake openings underneath the cabinet to avoid overpressuring the case
10x 120mm intake fans stacked (5 fans on each side (left and right) of the computer) attached to a Smart AV central command module that displays cabinet temperature with dedicated power to each pair of fans that runs off both 5v power adaptor and USB 3.2 power.
GPU temps will be monitored on a remote screen external from PC via Aida64
There is literally 20 intake fans cooling the computer and 7 exhaust fans exhausting the computer.
At the first sign of trouble it'll be turned off and reengineered. Depends on the failure point.
About the 1st layer of protection (heat and eletrical) - Glass Cloth Tape:
Glass Cloth Tape is a high-temperature, electrical insulation tape designed for use in 600-volt dry location applications that require resistance to high temperatures. The tape demonstrates excellent dielectric insulation properties and high heat resistance, making it ideal for electrical insulation in industries such as aerospace and military. Glass Cloth Tape is also used in insulation applications for furnace and oven controls, providing heat stable insulation for hot spot applications. The tape is suitable for various applications such as insulating electrical components in furnaces and ovens, coil wrapping outer wrap, and securing systems that require high mechanical strength and high temperature resistance.
About the 2nd layer of protection (heat and eletrical) - Silicone Rubber Gasket Sheet:
Silicone Rubber Gasket Sheet is a high-performance material that is commonly used in the electrical industry due to its excellent electrical insulation properties. It has a high dielectric strength, which means that it can resist high electric fields without breaking down and causing electrical failure. Additionally, silicone rubber has a low dielectric constant, which helps to reduce capacitance and enhance the performance of electrical components.
The material is also known for its outstanding resistance to heat, with a continuous operating temperature of +260°C and an intermittent temperature of +260°C. This makes it ideal for applications that are exposed to high temperatures, such as in motors and transformers.
It is an ideal material for electrical insulation applications due to its exceptional electrical insulation properties, excellent heat resistance, and ability to withstand high voltage.
About the 3rd layer of protection (heat and eletrical) - Molded polyurethane bumpers "feet"
Molded polyurethane (PU) is a versatile material that is known for its excellent electrical and heat insulation properties. It has a high dielectric strength, making it an ideal material for electrical insulation applications. PU has a high resistance to electrical breakdown, which helps to protect electrical components from damage due to electrical arcing or short circuits. Additionally, PU is an effective insulator against heat, with a high resistance to heat transfer. The material is also resistant to high temperatures, with a continuous operating temperature of up to 150°C, making it suitable for use in applications where high temperatures are present. Additionally, molded PU has a low thermal conductivity, which helps to reduce heat transfer, further increasing its effectiveness as an insulator. These properties, combined with its durability and versatility, make molded polyurethane a popular choice for a variety of electrical and heat insulation applications.
