Fix or replace your case fan when dust buildup should start with repeatable checks, not guesswork. Test settings, drivers, thermals, power behaviour, and recent changes so SA readers can isolate the cause before buying parts.
When dust buildup shows up on a case fan, clean it first; replace it only if it rattles, whines, or fails to spin after cleaning. A replacement 120mm fan like the Arctic P12 costs around R120 at Evetech, far cheaper than the GPU it protects.
Dust on a fan is usually cosmetic and a cleaning fixes it: power down, blow out the blades with compressed air and wipe the housing. Replace the fan only if, after cleaning, it grinds, wobbles, ticks, or refuses to spin up, all signs of a worn bearing. A healthy fan cleaned regularly lasts years, so do not bin a fan over dust alone.
If the bearing is gone, swap to a reliable Arctic P12 PWM (around R120): 1,800 RPM, around 56 CFM, 22.5 dBA. A failing fan lets temps climb, which can cost 5-10C on your CPU and GPU and trigger thermal throttling that drops frame rates. Replacing a dead fan restores airflow and protects far pricier parts for the price of a takeaway.
Dust pads on intakes and slight positive case pressure (more intake than exhaust airflow) keep dust out, so a refresh cycle stays months apart instead of weeks. Clean intake filters monthly in a dusty SA home. A tuned fan curve (around 40% idle, 80% by 75C) also avoids running fans hard enough to pull excess dust in during light use.

For a stable RTX 5070 starting point, use 1440p, the High preset, Ray Tracing Medium and DLSS Balanced, then measure the base frame rate before adding Frame Generation. Path tracing is a separate showcase mode, not the default.
HKC's 27-inch Shield 27Q560 runs QHD at 560Hz or 1280 x 720 at up to 1060Hz. The headline rate is specialised: resolution, sustained frame rate, ports and eventual South African support decide whether it is useful.
G.Skill's Trident Z5 Royal NeoX range pairs DDR5-6000 with timings from CL36 down to CL26 and adds an AMD EXPO ULL profile. Buyers still need a supported CPU, motherboard and BIOS before treating the lowest timing as guaranteed.
Diablo 4 HDR settings work best after Windows and the display are calibrated, then the game's black point, brightness and white point are adjusted in that order. Use visible shadow detail and controlled highlights, not copied values from another screen.
The best HOTAS for Elite Dangerous is a separate stick-and-throttle set with enough analogue axes for pitch, roll, yaw and thrust, plus local support. Evetech's captured flight-simulation sample lists the complete Logitech X56 at R4,999.
Nintendo Switch 2 docked VRR arrives with system version 23.0.0 and also requires a dock update. The connected TV or monitor and the running software must support VRR before the output can follow changing frame rates.
The Alienware AW3926QW is a 38.9-inch 5120 x 2160 OLED monitor that runs at 165Hz or 2560 x 1080 at 330Hz. Dell lists it at $1,099.99 in the US, while South African price and availability remain unconfirmed.
Steam Big Art Mode enlarges library artwork in Big Picture Mode and on Steam Deck, while the same beta adds configurable screensavers. Both features are optional and currently require the Steam beta client.
The best CPU for Roblox is a modern processor with strong per-core performance and enough platform headroom for the graphics card and other tasks. Roblox's minimum requirement is only a compatibility floor, not a sensible new-build target.
A QD-OLED text fringing fix cannot change the panel's physical subpixel layout, but correct scaling, native resolution, font tuning and viewing distance can reduce how visible the colour edges appear.
The Wallhack M-001 mouse uses a 53g magnesium shell, an 8000Hz wireless link and two hot-swappable batteries. Its $189.99 price is not a South African quote, so compare shape, support and the complete local cost.
