Check Price on Amazon

The MSI SUPRIM Liquid SOC is the definitive AIO-cooled 5090. It pairs a 360mm radiator with a factory overclock of 2565 MHz, and real-world testing shows it stays under 55°C even during extended 4K ray-traced gaming sessions. The 32GB of GDDR7 memory and 512-bit bus handle 8K texture workloads without any stutter, making it suitable for both gamers and content creators who render large scenes.

MSI’s proprietary water cooling design covers not only the GPU die but also the VRAM and VRMs with a full-coverage cold plate. This ensures every hot component stays within safe limits, eliminating thermal throttling even after hours of continuous load. The card itself is remarkably thin at just two PCIe slots, a major advantage for building in compact cases that support a 360mm radiator.

Owners report that the liquid cooling is virtually silent, with the pump noise staying inaudible inside a closed case. The only real drawback is the premium positioning, which places it above many air-cooled alternatives. For buyers who prioritize the lowest possible temperatures and a dual-slot footprint, this is the benchmark.

The ASUS ROG Astral LC pushes the boost clock to 2610 MHz in OC mode, the highest among the AIO-cooled 5090s in this guide. It uses a 360mm radiator with magnetic daisy-chainable fans that simplify cable management, and a full-coverage cold plate that cools the GPU die, VRMs, and memory simultaneously. A phase-change GPU thermal pad further improves heat transfer from the die to the cold plate.

During testing, owners report the card barely cracks 60°C under sustained load, with fan noise remaining low. The build quality is unmistakably ROG — a hefty metal backplate, ARGB lighting on the pump shroud, and a bundled GPU support bracket to handle the card’s weight. The magnetic fan connectors are a thoughtful touch for tidy builds, but they use a proprietary system that prevents swapping fan direction easily.

The price reflects the premium ASUS tax, landing it among the more expensive options. For buyers who want the highest factory boost clock available on a liquid cooled 5090 and don’t mind the extra cost, this card delivers every ounce of performance. Long-term durability remains a question given ASUS’s mixed track record, but early feedback is overwhelmingly positive.

The PNY RTX 5090 OC Triple Fan is an air-cooled card that delivers flagship performance at a noticeably lower price than its liquid-cooled peers. Its boost clock of 2527 MHz is competitive, and owners consistently report silent operation with zero coil whine — a rare achievement for any high-end card. Under load, temperatures settle in the mid-60°C range, which is excellent for air cooling on a 5090.

PNY uses a 3.5-slot triple-fan design with a vapor chamber and composite heatpipes to manage the 600W thermal envelope. The card is long and heavy, so a support bracket is included. Benchmarks show Cyberpunk 2077 at 4K with RT Overdrive running at 145-160 FPS, and Time Spy Extreme scores around 25,400. Undervolting to .895V yields even better-than-stock performance at just 63°C.

The power connector sits on top of the card, requiring 15-20mm of clearance for the cable bend, and the 600W power draw demands a robust PSU. For buyers who want a premium 5090 without paying the liquid cooling premium, this is the strongest air-cooled contender. PNY is an American company, which some users prefer for support purposes.

The ZOTAC RTX 5090 Solid OC is designed for users who want raw performance without flashy RGB lighting. Its IceStorm 3.0 cooling system uses three 100mm BladeLink fans, a vapor chamber, and composite heatpipes to keep temperatures in check. The boost clock sits at 2422 MHz, slightly lower than some rivals, but the card remains quiet under full load.

Owners praise the lack of RGB, with one calling it “seriously powerful but quiet.” The card fits well in a H7 Flow case, and the bundled GPU support stand is easy to install. Performance is as expected for a 5090: high 4K FPS with path tracing enabled. The Dual BIOS feature allows switching between quiet and performance fan profiles depending on your workload.

Some users have noted Nvidia driver instability affecting the RTX 50 series, though this is a platform issue rather than a ZOTAC-specific problem. The card’s slightly lower boost clock makes it a better fit for buyers who prioritize a clean, understated build over chasing every last megahertz. Good case airflow is essential to get the most from this air-cooled design.

The GIGABYTE AORUS Master is a fully air-cooled card that still demands serious attention. Its 2655 MHz boost clock is among the highest of any 5090, and the WINDFORCE cooling system manages to keep temperatures around 65°C during gaming sessions. The card features 32GB of GDDR7 memory on a 512-bit bus, making it fully future-proof for upcoming 8K and high-VRAM workloads.

Owners praise the consistently low fan noise and excellent thermal control. One reviewer noted that the card under-volts well, maintaining performance while reducing power draw. A unique power issue indicator light is included, which alerts the user to potential power delivery problems — a feature absent from many competing 5090s.

The card is large, weighing almost 6 pounds and measuring over 14 inches long, so case compatibility and a support bracket are non-negotiable. The pre-overclocked profile delivers excellent performance out of the box, and the bundled software works without RGB conflicts according to user reports. For buyers who want flagship air cooling with the highest boost clock available, this is the top air-cooled pick.

The MSI RTX 4090 SUPRIM Liquid X is the previous-generation flagship, but it remains a potent option for buyers who want liquid cooling at a lower entry point. It packs 24GB of GDDR6X memory, 16384 CUDA cores, and a boost clock of 2640 MHz. The AIO cooler keeps temperatures low, and the card occupies only two PCIe slots — a rarity for any liquid-cooled GPU.

Owners report that the liquid cooling is effective and quiet in a closed case, though some have noted coil whine under high load in open-build setups. The card handles 4K gaming and professional workloads with ease, including demanding rendering and AI tasks. The thin profile makes it an excellent choice for space-constrained builds that can accommodate the radiator.

The main trade-off is raw compute performance: the 5090 offers roughly 30-40% more rasterization power and significantly better ray tracing capability. For buyers who prioritize liquid cooling and a lower cost over absolute peak performance, this is the sensible choice.

The air-cooled MSI SUPRIM SOC shares the same premium design language and 32GB GDDR7 memory as its liquid-cooled sibling but relies on a massive triple-fan heatsink. With a boost clock of 2580 MHz and a 512-bit memory interface, it outputs exceptional performance out of the box. Stock temperatures idle around 40°C and reach 82-88°C under load — higher than any liquid solution but still within safe limits.

Owners have reported impressive overclocking headroom, with average clock speeds reaching 2887 MHz and peaks up to 3155 MHz. The card is massive, weighing over 8 pounds, and comes with a stabilizing bracket. Some users have modded the card with additional heatsinks and fans to drop load temperatures to 62°C, though this is not necessary for normal operation.

The biggest concern is the power connector. One detailed owner report identified that third-party heatsinks can blow hot air directly onto the power plug, potentially contributing to melting issues. Users should avoid blocking airflow around the power connector. For buyers who want SUPRIM build quality but prefer air cooling, this card delivers flagship-level performance with proper thermal management.
