Deepcool Z4 (Silicone-Based/Non-Conductive/4.5 W/mK Entry Paste) Review
Deepcool Z4 is an entry-level thermal paste from Deepcool's Z-series, rated 4.5 W/mK in a 2g tube.
It sits between Z3 and Z5 in Deepcool's own lineup, a beginner-friendly non-curing paste rather than an overclocking pick.
Thermal Performance and Conductivity
4.5 W/mK sits above Deepcool's own Z3 (3.5 W/mK) but below Z5 (1.46 W/mK per Deepcool's own site, oddly lower than Z3/Z4 depending on formulation) and well below the enthusiast-tier Z9/Z10/DS-series.
Compound Type and Composition
Environmentally-friendly insulating silicone material with no added preservatives or metal particles per Deepcool's own product page, non-curing with no corrosive additive, rated -50C to 220C with a specific gravity of 2.6 g/cm3.
Comparison to Sibling Products
Against Deepcool's own Z3 and Z3 Pro, Z4 is a similar entry-tier option, this is a beginner-friendly bundled-cooler-style paste, not a competitor to Deepcool DS7/DS9 or Z9/Z10.
