Discussion Overview

The discussion revolves around the need for different voltage levels on a computer motherboard, such as 1.5V, 5V, and 12V. Participants explore the reasons behind these varying voltage requirements, touching on aspects of computer architecture and component functionality.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants assert that most computers require multiple voltage levels, while noting that embedded systems might use a single voltage.
  • One participant mentions the heat dissipation of processors, questioning why it occurs and comparing it to a heater.
  • Another participant challenges the claim of having "opened the processor," suggesting that it is more likely the computer case was opened instead.
  • There is a mention of the processor being "lock based" with many pins, but the relevance of this point is questioned by others.
  • A participant suggests that different circuits may be operating at various voltages, indicating a possible understanding of the complexity involved.

Areas of Agreement / Disagreement

Participants generally agree that multiple voltages are used in computers, but there is disagreement regarding the specifics of processor access and heat dissipation, with no consensus on the implications of these points.

Contextual Notes

Some assumptions about the nature of processor construction and heat generation remain unresolved, and the discussion does not clarify the exact roles of the different voltage levels.

Hello,
What computer need different voltages at mother board like 1.5V 5V 12V etc??

Pretty much all of them. It may be that there are some for embedded systems that use a single voltage, but anything for a PC will use several voltages.

PC will use several voltages.

i have open the processor it was dissipating a lot of heat, why?
small few inches more than heater or same.

I SERIOUSLY doubt you have "opened the processor". More likely you have just opened the computer. The processor is the CPU chip and you can't "open" it without destroying it.

Electrical components get hot and computers have particularly dense packing so there can be a lot of heat in a small space.

Hello,
The processor is lock based there are lot of pins

Yes. So what is your point? What does "lock based" mean?
 
ok i got it there may be different circuit operating...
