Quick Answer

For 95% of SA builders, quality thermal paste is the right choice - liquid metal only buys you roughly 5-10 degrees on a delidded or heavily overclocked CPU and carries real risk. A premium paste like Thermal Grizzly Kryonaut or Arctic MX-6 costs around R250-R450 and handles even a Ryzen 9 or Core i9 comfortably, while liquid metal sits near R600-R900 and can short components if it spills onto the board.

Temperature deltas in plain numbers

Swapping a dried-out stock paste for a fresh premium paste typically drops load temps 6-12 degrees. Going from premium paste to liquid metal on a bare die adds only about 5-10 degrees more headroom. On a stock-clocked CPU under a good air or 240mm AIO cooler, that final delta rarely changes whether you hit your clocks, so paste is the sensible pick for most.

When liquid metal earns its risk

Liquid metal makes sense if you are delidding, running an extreme overclock, or fighting a thermally limited laptop on a high-wattage chip pushing 200W or more. It is electrically conductive and corrodes bare aluminium coolers, so it demands careful application, nail-polish insulation around the die, and a copper or nickel-plated coldplate. For a first build, that risk usually is not worth 5 degrees.

What to buy at Evetech

Most builders should grab a tube of Arctic MX-6 or Kryonaut, currently stocked at Evetech in the R250-R450 range - one tube does several applications. If you genuinely need liquid metal, Thermal Grizzly Conductonaut sits near R600-R900 and should only go on a compatible nickel-plated cooler.

FAQ

Is liquid metal worth it over thermal paste?

For stock or mild overclocks, no - premium paste gives 90% of the benefit at half the price and none of the spill risk. Liquid metal only pays off on delidded or extreme-OC setups.

How often should I reapply thermal paste?

Every 3-5 years, or when load temps creep up. A quality paste like MX-6 stays stable for years, so you rarely need to redo it unless you remove the cooler.

Can liquid metal damage my PC?

Yes - it is conductive and corrodes aluminium. A spill onto the motherboard or contact with an aluminium coldplate can permanently damage parts, which is why paste is safer for most builders.

Pick up a tube of premium thermal paste at Evetech and reapply if your CPU load temps sit above 85 degrees - it is the cheapest cooling upgrade you can make.
