High-Performance Thermal Paste
The 100% fan ramp is a firmware-level safety protocol triggered when the GPU's internal thermal sensors detect a 'hotspot' temperature exceeding safe operating limits, typically due to thermal paste pump-out or dry-out. Even if average core temperatures appear normal, a localized hotspot on the silicon will trigger an emergency shutdown of the display controller. Applying a high-viscosity non-conductive paste restores the thermal bridge between the die and the heatsink.

850W 80+ Gold ATX Power Supply
RTX 30-series cards are prone to high-frequency transient power spikes that can exceed the rated capacity of older or lower-wattage power supplies. When the PSU's Over Current Protection (OCP) is triggered by these millisecond-scale surges, the GPU experiences a momentary voltage drop, causing the driver to crash and the card to enter a 'headless' failsafe mode with fans at maximum speed.

Individual 8-Pin PCIe Power Cables
Using a single 'pigtail' or daisy-chained PCIe cable to power a high-draw card like the 3070 can lead to significant voltage sag and heat buildup at the connector pins. Providing independent cables for each power input on the card ensures stable amperage delivery to the VRMs, preventing power-starvation-induced black screens during high-load 'Boost' clock states.
