How Efficient Is the Cooling System?

The UM590 uses a dual-fan cooling system with copper heat pipes and graphene coating to dissipate heat efficiently. Under load, noise levels remain below 40dB, balancing performance and acoustics. Thermal testing shows CPU temperatures stabilize at 85°C during sustained workloads, ensuring reliability without throttling.

The advanced cooling architecture combines active and passive cooling strategies. The graphene-coated heat spreader improves thermal conductivity by 15% compared to traditional aluminum solutions, while the dual 5V fans adjust RPM between 800-2800 based on workload. During gaming sessions, this system maintains GPU temperatures at 68-72°C, preventing performance drops. Users can monitor thermal metrics through the pre-installed MINISFORUM Center software, which offers three fan profiles: Silent (25dB max), Balanced, and Performance modes.

Cooling Component	Specification
Heat Dissipation	45W TDP capacity
Fan Noise	22-39 dB(A)
Thermal Interface	Graphene + Copper composite

Can You Upgrade the RAM and Storage?

Yes, the UM590 supports user-upgradeable DDR4 RAM (up to 32GB) and dual M.2 2280 PCIe SSD slots (up to 1TB each). The tool-free design allows easy access to internal components. A 2.5-inch SATA III bay is also available for additional HDD/SSD storage, making it adaptable for expanding workloads or media libraries.

The device uses standard 260-pin SO-DIMM slots that accept DDR4-3200MHz modules. For storage expansion, the dual PCIe 3.0 x4 NVMe slots support RAID 0/1 configurations, achieving sequential read speeds up to 6,900MB/s when striped. The 2.5″ drive bay accommodates 7mm/9.5mm thick SATA SSDs or HDDs, though adding a mechanical drive requires purchasing a separate mounting bracket.
