Bykski 360mm AIO Liquid GPU Cooler For ASUS ROG Astral Gaming GeForce RTX 5090 32GB BTF OC (B-FRD-AS5090MATRIX-X-360)
US import duties and tariffs are included in every price.
Sealed. Filled. Bled.
A complete liquid cooler for the ASUS ROG Astral Gaming GeForce RTX 5090 32GB BTF OC, sealed at the factory. One copper block covers the GPU, the memory and the power stages; the radiator mounts at the front or top of your case and pushes the heat out. Strip the stock cooler, fit the block, mount the radiator. No filling, no bleeding, no leak test.
Heat leaves the case instead of heating everything else in it
A stock air cooler blows the ASUS ROG Astral Gaming GeForce RTX 5090 32GB BTF OC's heat into the case, where your other cards and the CPU have to deal with it. This kit carries it through the tubing to the radiator, and the fans push it straight out of the case.
The noise moves too. Three big fans turning slowly on the radiator replace a small blower screaming an inch from the chip. Same heat removed, most of the noise gone.
Built for a card that never gets a break. A ASUS ROG Astral Gaming GeForce RTX 5090 32GB BTF OC in a server can run at full load for hours at a time, and this cooler is sized for that, not for an evening of gaming.
The pump is inline, not on the block
On most all-in-one coolers the pump is built into the block. On this kit it is inline, in the tubing between the block and the radiator, and nothing is mounted to the card.
There is nothing to mount and nothing vibrating against the card. Because the pump is not pressing against anything, it runs quieter than a pump built into a block.
It is compact and powerful: a 40 mm can, 51 mm tall, moving 450 liters an hour, at 7000 RPM on a 4-pin PWM header.

About this part
The Bykski 360mm AIO Liquid GPU Cooler (B-FRD-AS5090MATRIX-X-360) is a sealed, pre-filled liquid cooler for a single graphics card. It is for builders who want a water-cooled card without planning and filling a custom loop. It fits the ASUS ROG Astral Gaming GeForce RTX 5090 32GB BTF OC and the ASUS ROG Matrix Platinum GeForce RTX 5090 32GB 30TH, with an acrylic-top block machined for their circuit board.
Block, inline pump, tubing and radiator come joined and filled, so the work is fitting the block to the card and the radiator to the case. The pump rides in the tubing instead of on the card, so nothing vibrates against it, and the 360 mm radiator with three PWM fans gives the heat a large surface to leave through.
- Kit: radiator, inline pump, tubing and water block with backplate, pre-assembled and pre-filled
- Fans: 3 x 120 mm PWM, 5V ARGB
- Thermal pads for the memory and power stages
- Thermal paste for the GPU chip
- Mounting hardware

Machined for the ASUS ROG Astral Gaming GeForce RTX 5090 32GB BTF OC board
Two cards with the same name can be built on different circuit boards, and the block only fits the one it was machined for. This is that board. Check your card in the Block Finder first. If you are still not sure, send us a picture of your card with the cooler off before you order.
ONLY Compatible with:
- ASUS NVIDIA 5090 - ROG ASTRAL GAMING GEFORCE RTX 5090 32GB BTF OC
- ASUS NVIDIA 5090 - ROG MATRIX PLATINUM GEFORCE RTX 5090 32GB 30TH
Measure before you order
Two things have to fit: a 360 mm radiator with its fans, and the card with the block on it. The tubing is flexible, so the pump and the hoses go wherever your case has room, behind the motherboard tray if that is where the space is. Everything here is the same on every GPU cooler we sell except the block, which is sized to the card.
Sealed kit, or just the block
Same cold plate, two ways to buy it, and what happens if you keep the cooler the card shipped with.

As the card ships
|
|
|---|---|---|---|
| You already have | A case with a 360 mm radiator mount. Nothing else. | A working water-cooling loop: pump, radiator, reservoir, fittings, coolant. | The card and the cooler it came with: a passive fin stack or a small blower, built to be fed by a server's front-to-back airflow. |
| Day one | Remove the stock cooler, fit the pads and the block, mount the radiator. Done. | Same block install, then plumb it into your loop, fill and bleed. | Plug it in. In a rack with a cold aisle it runs as designed. In a workstation or desktop case, nothing pushes air through the fin stack. |
| Serviceable | Sealed. Nothing to fill, bleed or top up. | Every part, because it is your loop. | Nothing to service, and nothing to improve: the cooler can only move the heat the case pushes through it. |
| Best for | Servers and workstations that need it running this week. | A build that already has water in it. | The rack it was designed for. Not a desktop, a workstation or an open bench, where it throttles under sustained load. |
