Questions about this item

Will the 4-pin CPU connector need to be replaced later?

The 4-pin CPU power plug is a fixed, original-style connector with identical pinout and cable length to the factory unit, so no wiring change or connector swap is required.

What limits continuous 24/7 operation at full load?

Rated continuous output is 260W on a single +12V rail; the thermo-controlled fan and industrial-grade capacitors are designed for stable 24/7 operation within that limit.

How much heat and noise does the fan produce when running all day?

A thermo-controlled quiet cooling fan adjusts speed to load, while high-temperature-resistant capacitors and Platinum efficiency keep heat and noise low during sustained daily use.
