What a 2700RPM Pump Speed Really Means for Your AIO CPU Cooler
A 2700RPM pump spins its impeller 2700 times a minute to push coolant round the loop. Faster flow moves heat from the CPU block to the radiator, though a quicker pump can be a little louder. The Antec Omni Matrix 360 at R999 pairs it with an ARGB head.
How to Connect Three PWM Fans and ARGB Lighting to Your Motherboard
Plug the three pre-connected 120mm fans into one PWM fan header, since they run from a single cable. If the lighting has its own lead, send it to the addressable header, usually labelled ARGB. Evetech's Omni Matrix 360 at R999 follows that same plan.
Checking AIO Cooler Compatibility with LGA 1851, LGA 1700, AM5 and AM4
Compatibility starts with your motherboard socket. The Antec Omni Matrix 360 covers LGA 1851 and LGA 1700 sockets, as well as AM5 and AM4. Confirm the socket name before you open the box, since the mounting hardware differs between platforms.
PWM vs Fixed-Speed Fans: How Does Fan Control Affect CPU Cooling?
A PWM fan changes speed on a board signal, while a fixed-speed fan runs at one rate. PWM lets a curve ramp up under load and stay quiet at idle. In a small flat in Durban with a shared lounge, quiet idle curves matter, and the Omni Matrix 360 uses PWM fans.

Edge sleeping tabs: manage inactive pages and exceptions
Edge sleeping tabs reduce the resources used by inactive pages. Review the setting and important-site exceptions before disabling it, and test live work separately from pages you only keep for later.
How to fly the hidden Google Earth flight simulator, and what real sims add
Open Google Earth Pro on a Windows PC and press Ctrl+Alt+A to fly an F-16 or SR22 over real terrain. Keyboard flying over Table Mountain is a fun taster, and a USB stick like the R3,999 Turtle Beach VelocityOne Flightstick is where proper sims begin.
Can you 3D print car parts at home that are safe to actually use?
Yes for clips, trim, mounts and brackets, but never for brakes, steering or seatbelts. A parked car in a South African summer gets hot enough to soften PLA, so PETG from R219 a spool or ABS at R299 is the safer choice for anything that lives inside the cabin.
Does a WiFi extender fix weak signal on a Vuma fibre line at home?
An extender fixes weak WiFi on a Vuma line only when a room or two sits just past the router's reach. Vuma runs the fibre but your ISP supplies the router, and a R919 TP-Link RE450 suits a small gap, while brick double-storeys need mesh or a cabled access point.

Targus DOCK402: check charging and single-display compatibility
Targus DOCK402 combines a mobile dock with a built-in GaN charger. Its useful buying checks are host power negotiation, USB-C video support and the single-display limit, rather than assuming every USB-C laptop gets the maximum charging and resolution.
Edge default search engine: change address-bar searches safely
Edge default search engine controls searches typed in the address bar. Choose a supported search provider in browser settings, then test the address bar separately from a website search box or a new-tab page before assuming the change failed.
Edge block pop-ups: keep protection and allow one trusted site
Edge block pop-ups can stop unwanted windows while permitting a trusted site that needs one. Check the exact site exception and distinguish pop-up windows from adverts inside a page and website notifications before turning off protection broadly.
Edge website notifications: stop alerts from an unwanted site
Edge website notifications are controlled per site. Block the unwanted origin in browser permissions instead of muting every Windows alert, then check whether the interruption was a site notification rather than a pop-up or a message inside a page.
