Fans (Radiator)

# Radiator Fans: 2x Corsair 120mm PWM

#### Benchmark Justification

A 240mm radiator takes 120mm fans. There is no 140mm option on this loop, which is why every 140mm fan in this build is somewhere else.

Verified during the Project 9900K ultra-high refresh rate validation runs. Every component is cherry-picked to eliminate frametime spikes, micro-stuttering, and DPC latency overhead in competitive esports titles.

Hardware Verification & Care

## Component Procurement & Testing FAQs

Crucial advice on buying used enthusiast PC hardware, silicon binning, and thermal maintenance.

Ctrl+F

Silicon degradation manifests as instability at stock or mild voltages. Test the CPU by running OCCT CPU / Linpack at stock voltage; if errors occur within 10 minutes, the silicon has experienced degradation.

For used graphics cards (especially OEM or previously mined units), check VRAM junction temperatures and inspect HWInfo64 for "PCIe Bus Errors" (WHEA 17/19).

Replacing dried thermal pads and applying PTM7950 to the GPU core restores used hardware to factory thermal performance.

Key Takeaway:
Always check WHEA errors in HWInfo64 and verify voltage stability on second-hand hardware.
