DeepCool CYCLOPS WH vs In Win D5computed

Datasheet figures next to each other, and the airflow balance, pressure verdict and case air heating that the fans in each box compute to behind that case's own front. Calculated with the CaseFlow model, not measured.

With a reference pressure-optimized fan on every mount the CYCLOPS WH moves more air. The stock fans of the D5 are named without figures behind them, so its stock columns stay empty. The pressure verdict describes the stock fan set, not the case: stronger or extra intake fans in the free mounts, or slower exhaust fans, turn a negative balance positive.

How these numbers are computed

Each stock fan contributes CFMmax · derate · rpm/rpmmax behind its wall's mounting class: filtered mesh front and side mounts as dust filter, bottom as floor + filter, top and rear as open grille, solid and glass fronts as side-slit intake at roughly half of a mesh front. Front, bottom and side blow in; top and rear blow out.

MountingAirflow bladesPressure-optimized
Open grille0.88 (0.80–0.95)0.88 (0.80–0.95)
Dust filter0.70 (0.60–0.80)0.78 (0.70–0.86)
Floor + filter0.64 (0.52–0.74)0.72 (0.62–0.80)
Solid or glass front0.50 (0.40–0.62)0.58 (0.48–0.68)

Worst case sums intake at the low end of each band and exhaust at the high end; positive there means positive regardless of how the estimates fall. Case air: ΔT = 3.1 · W / throughput (m³/h), with an open-cooler GPU putting its full board power into the case air plus board, RAM and drives. Capacity puts a reference pressure-optimized fan on every mount at max rpm — 120 mm 60 CFM, 140 mm 75 CFM — a generic good fan, not a product.

Mount counts, radiator support and clearances are datasheet figures. Nothing here is measured; the same model runs in CaseFlow.
