Inline pump 360 radiator, 63 mm with fans Sealed, filled, bled

GPU AIO · Gigabyte RTX 3090 / 3080 Gaming OC

Sealed. Filled. Bled.

A complete liquid cooler for the Gigabyte RTX 3090 / 3080 Gaming 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.

Radiator mount needed

A workstation mid-build on a desk: the kit fitted to the card, block and tubing to the radiator in the top of the case

Warm air out the top hot line return

Where the heat goes

Heat leaves the case instead of heating everything else in it

A stock air cooler blows the Gigabyte RTX 3090 / 3080 Gaming 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 Gigabyte RTX 3090 / 3080 Gaming 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 inline pump, exploded: housing, impeller and the two tubing connections

The part you cannot see in a photo

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 is a sealed loop that arrives pre-assembled, pre-filled, and pre-bled. It eliminates custom loop assembly while cooling the GPU chip, memory, and power stages with a 360 mm radiator.

An inline pump in the tubing run isolates vibration from the card, allowing the water block to maintain even mounting pressure. The clear acrylic top provides a direct view of coolant flow over the GPU chip.

In the box

Compatibility is decided by the circuit board, not the name on the box

Machined for the Gigabyte RTX 3090 / 3080 Gaming 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.

The second fit question

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.

06Pump, inline on the tubing40 x 51 mm

07Block for this card, length x height200.00 x 150.00 mm

08Block thickness, including the ports26.50 mm

09Kit laid out straight, top of radiator to block (reference only)480 mm

Measure the radiator mount, not the whole kit. Your case needs a 360 mm radiator position with 63 mm of depth for the radiator and fans together. The 480 mm figure is the kit stretched out straight, not a clearance you need: the hoses bend, and the pump tucks wherever there is room.

Not sure this is the one?

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.

	This kit B-FRD-GV3090GMOC-X	The bare block N-GV3090GMOC-X	Stock cooling 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.

Questions people ask about this cooler

Answers specific to B-FRD-GV3090GMOC-X. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

Do I have to build a loop?

No. It arrives sealed, filled and bled. Remove the stock cooler, fit the block, mount the radiator and plug in the fans and the pump. No filling, no bleeding, no leak test, and no coolant to buy.

What is in the box for the thermal interface?

Thermal paste for the GPU chip and thermal pads in strips for the memory and the power stages. The block cools the front of the card; the back gets the aluminum backplate.

Will it fit my card?

Compatibility is decided by the circuit board, not the name on the box. The block in this kit is machined for the Gigabyte RTX 3090 / 3080 Gaming OC board, and the list on this page is the complete list. Check your card in the Block Finder first; if you are still not sure, send us a photo of the board with the cooler off before you order. Part number B-FRD-GV3090GMOC-X.

Will the radiator fit my case?

Your case needs a 360 mm radiator position with 63 mm of depth for the radiator and fans together. The tubing is flexible, so the pump and the hoses go wherever there is room, behind the motherboard tray if that is where the space is. Measure the radiator mount: the 480 mm figure on the drawing is the kit laid out straight, not a clearance you need.

Why is the pump not on the block?

It is inline, in the tubing between the block and the radiator. Nothing is mounted to the card and nothing vibrates against it, so it runs quieter than a pump built into a block. The loop is sealed, so the pump is not a part you service.

Can I cancel my pre-order?

Yes. A pre-order can be cancelled any time before it ships, for a full refund. Nothing is committed until it leaves Boise.

Is liquid always worth it?

No, and we will say so. A single card with room around it is fine on air. It changes when cards are packed together, when the card is passive, when the case is small, or when the machine runs at full load for hours rather than minutes.

Who handles the warranty?

BYKSKI.US, the exclusive US distributor, from Boise, Idaho. Claims are handled domestically rather than returned to an overseas factory.
