Most PC components consume a strictly defined amount of electricity. In some cases, reducing this volume or reducing component voltages can increase system performance or improve its efficiency. Howtogeek.com portal speakWhat parts of a PC should never be underestimated?

Integrated CPU
In general, reducing voltage is an easy way to get many benefits, from lower power consumption to lower temperatures, quieter fans, and increased durability. On older chips, this procedure was available and was even encouraged by the manufacturers themselves, who provided tools for power regulation.
But today the situation is different. A significant number of manufacturers prohibit voltage drops at the firmware level. Probably due to Plundervolt, a specific vulnerability in Intel processors that allows access to protected memory via power manipulation. In this regard, many 10th and 11th generation chips block voltage reduction at the software level, which forces enthusiasts to resort to other tools. For example, to configure power settings through BIOS.
However, reducing voltage to the integrated CPU is not worth your time. The potential problems, while unlikely, do not outweigh the small benefits.
Integrated GPU
The discrete processor and video card are not difficult to underestimate. But integrated PC components are a different story. The fact is that separate computer components have their own power supply and cooling capabilities, while the video card and integrated processor share the same resources. Therefore, fine-tuning even one of the two chips is a difficult task, as any parameter change will affect both components.
Additionally, the simultaneous impact of these changes makes system testing difficult. One component may pass the benchmark, while another may have trouble loading. Getting the exact desired result on an integrated chip is quite enough. Of course, there are exceptions to this rule, but even they rarely give you a headache.
DAM
Reducing RAM voltage levels is always a bad idea. Such a procedure not only does not bring any benefits to the system, but also threatens many problems, such as endless boot loops, blue screens and data loss.
The problem arises because memory modules, such as DDR4 and DDR5 dies, have very strict voltage tolerance limits. When EXPO or XMP profiles are enabled, RAM will exceed these limits to stabilize at higher clock speeds. Even if you reduce the voltage just a little, there's still a risk of application errors or memory errors. In the worst case, the PC will refuse to turn on.
Fans and pumps for housing and public services
Finally, the last component that is best left alone is the fan and pump. While the prospect of reducing liquid cooling system voltage may sound appealing, the consequences could be catastrophic. Modern ventilators are built around thermal adaptability; System components respond dynamically to CPU temperature.
In a closed cooling system, the pump requires a certain minimum voltage to respond to changes in temperature demand. When voltage is reduced, the pump's ability to adjust to these changes may be affected. While this is unlikely to cause damage to the LCS itself, the voltage drop will negatively affect PC cooling under high load.
