Upgrading RAM in a mini PC involves checking compatibility with your device’s motherboard. Most mini PCs use SODIMM DDR4 or DDR5 modules. Open the chassis, locate the RAM slots, and replace or add sticks while grounding yourself to prevent static damage. For example, Intel NUC models often support up to 64GB RAM, doubling multitasking efficiency.

What Storage Upgrades Work Best for Mini PCs?
Swapping HDDs for NVMe SSDs boosts read/write speeds up to 7,000 MB/s. Some mini PCs, like the ASUS PN series, include dual M.2 slots for RAID configurations. Alternatively, use 2.5-inch SATA SSDs for budget-friendly storage expansion. External USB-C or Thunderbolt drives also offer plug-and-play solutions without opening the chassis.
For users prioritizing speed, NVMe drives are ideal for applications like video editing or gaming. RAID 0 setups can further enhance performance by striping data across two drives, though this increases failure risk. Budget-conscious upgrades might focus on SATA SSDs, which still outperform traditional HDDs by 4–5x. Below is a comparison of storage options:
| Type | Speed | Cost per GB |
|---|---|---|
| NVMe SSD | 3,500–7,000 MB/s | $0.08–$0.15 |
| SATA SSD | 500–550 MB/s | $0.05–$0.10 |
| HDD | 80–160 MB/s | $0.02–$0.04 |
Which Cooling Solutions Prevent Mini PC Throttling?
Aftermarket thermal paste (e.g., Arctic MX-6) reduces CPU temps by 5–10°C. Add mini heatsinks or replace stock fans with Noctua’s 40mm PWM models. Undervolting via ThrottleStop or Intel XTU minimizes heat generation. For extreme builds, liquid-cooled external docks can dissipate heat from high-TDP processors like AMD Ryzen 9.
Passive cooling solutions, such as copper shim mods or heat pipe assemblies, are effective for silent operation. Mini PCs with limited internal space benefit from external cooling pads with adjustable fans. Monitoring software like Core Temp ensures thermal limits stay within safe thresholds. For example, the Minisforum HX99G sees a 12% performance boost after upgrading its thermal interface material and adding auxiliary exhaust fans.
Can You Add External GPUs to Mini PCs?
eGPU support depends on Thunderbolt 3/4 or USB4 ports. Enclosures like Razer Core X house desktop GPUs (e.g., NVIDIA RTX 4060) for gaming or AI workloads. Bandwidth limits may reduce performance by 10–15%, but eGPUs still transform mini PCs into capable workstations.
Expert Views
