4000D Airflow: price, specs & release date

Two whitelisted testers cover this case, both at its September 2020 launch. TechPowerUp ran a dedicated 4000D Airflow review with its own temperature and noise testing on a supplied sample. Tom's Hardware ran a combined 4000X / 4000D review — the verdict and Editor's Choice are aimed at the pricier 4000X RGB, but the article includes separate 4000D Airflow thermal, acoustic and fan-speed data, which is what is cited here. Every quote and measured figure below was confirmed as a literal substring of the fetched article text; note both reviews are paginated, so the quotes live on sub-pages (Tom's verdict box on page 1 and its testing/conclusion on page 3; TechPowerUp's on its page 7 conclusion) rather than on the landing URL. Both testers praise the clean, understated exterior at the roughly $80 asking price ($79.99 MSRP per TechPowerUp, $80 per Tom's) and both want a second front USB-A port. Only Tom's produced measured cooling and acoustic results. No other outlets were checked in this pass, so the absence of others here is not evidence that none exist. Praised: Clean, understated minimalist exterior with a solid feel for the roughly $80 asking price; Good value against competitors — Tom's calls the small Corsair premium well worth it, TechPowerUp calls it a beautiful and capable case for the price; Practical build details that ease assembly and cable routing (side panels that unhook and swing out, Velcro cable channel, plentiful zip-tie anchors); Effective mesh-front cooling despite shipping with only two fans; Very quiet in stock form — the quietest case on Tom's test bed when measured without a GPU installed; Dust filters on every intake area, including a metal-mesh top filter. Flagged: Only one front USB-A port; both testers wanted a second USB 3.0; Heavily tinted glass side panel hides non-RGB hardware — TechPowerUp calls the tint too heavy, Tom's notes it as a deliberate trade-off it is willing to accept; Liquid-cooling constraints — TechPowerUp says support is not as vast as other ATX cases; Tom's warns thick front radiators won't clear the PSU shroud cutout and the top is limited to 280 mm; Stock voltage-controlled fans top out around 1300 RPM — not fast enough for extreme cooling demands; Feature-light for the $80–$100 bracket — no fan or RGB controller, no 3.5 mm jack adapter, only two fans while rivals ship up to five. (From 2 tester reviews, 2 lab-tested.)
