Side-by-Side Comparison
Thermal Grizzly DeltaMate GPU Block for MSI Suprim GeForce RTX 5090 vs NZXT H2 Flow
Standardized 5-pillar engineering audit, thermal telemetry, verified longevity metrics, and complete technical specification diff.
● HIGHLY RATED
Composite Score:
4.4
/ 5.0
Exemplary dual-coldplate GPU block boasting borosilicate glass construction and guided alignment tooling, restricted by single-PCB lock-in and a €549.90 barrier.
● HIGHLY RATED
Composite Score:
4.4
/ 5.0
The NZXT H2 Flow delivers remarkable spatial density by accommodating 331 mm triple-slot GPUs and 280 mm radiators in a 20.7L steel-and-glass enclosure, trading tower air cooler height and ATX power supply support for a compact desk profile.

Thermal Grizzly DeltaMate GPU Block for MSI Suprim GeForce RTX 5090: Strengths & Caveats
✔ Advantages
- Decoupled dual-coldplate copper architecture optimizes thermal dissipation between GPU core and VRM/VRAM
- Superior material selection incorporating CNC nickel-plated copper, anodized aluminum, and durable borosilicate glass
- Included 'The Oracle' alignment PCB eliminates mounting misalignment and pad compression variance
✖ Documented Caveats
- Substantial price tag of €549.90 represents a significant premium over standard liquid blocks
- Strictly locked to the MSI Suprim RTX 5090 PCB layout with zero cross-card compatibility
NZXT H2 Flow: Strengths & Caveats
✔ Advantages
- Accommodates full-length triple-slot graphics cards up to 13.03 in (331 mm) and 2.56 in (65 mm) thickness
- Supports up to 280 mm liquid cooling radiators within a compact 20.7-liter footprint
- Equipped with a high-bandwidth USB 3.2 Gen 2x2 Type-C front I/O port
- Includes two pre-installed F120Q 120 mm exhaust fans
✖ Documented Caveats
- CPU cooler height clearance is strictly capped at 2.95 in (75 mm), precluding tower air coolers
- Power supply compatibility is restricted to SFX and SFX-L units only
