About this part

Built for the NVIDIA RTX PRO 6000 Blackwell Workstation Edition, this full-cover block cools the GPU chip, memory and power stages in one pass. Workstation cards run at board power for hours on end, and once the stock heatsink is removed the loop is the card's only cooling path.

Chassis airflow has to cover everything else in the case, so this block moves the card's heat into the loop instead. The nickel-plated copper base is 0.35 mm thick with fine micro-channels under its fins, so the coolant has plenty of copper to pull heat from.

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.

	The All-in-One (AIO) kit B-FRD-RTXPRO6000-WS-360	This block N-RTXPRO6000-WS-SR	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, install 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.

What buyers said

Left by people who bought this part here. Compatibility reports are the useful ones — if you installed it, say which board.

Excellent Product!

I received the water block within the estimated timeframes. The quality is top notch. Installation was easy and most importantly, the product worked perfectly. I am seeing about a 50% reduction in temps on average. The backplate doesn't have any active cooling like the front does, so I had to rearrange some fans to blow air on the backplate. I haven't been able to get the card temps above 50C at sustained full load, which is awesome.

Water Block and Backplate For NVIDIA RTX PRO 6000 Blackwell Workstation Edition (N-RTXPRO6000-WS-...

The WB is just awsome, with 480mm radiator, the GPU tm is now at 50° under full load of 600w. However the backplate is covering a lot of memory modules while it did not have any cooling method, maybe the use of a suplementatry water loop to cool the backplate will just be perfect.

Also the front of the WB is not esthetically correct because it is not covered and exposed the internal structure of the gpu.

Except these two thinghs, the WB is perfect.

Thanks Bykski.

Impressive performance on my RTX 6000 but have small defect on some **** hole

Overall, very impressive performance keep my RTX 6000 at ~50C on full load. Installation are pretty straight-forward however, I do find two **** hole is not precisely manufactured so I have to find some way to re-drill and get screws in.

What installing it actually involves

Three steps, in the order that matters. The one people get wrong is the first.

Confirm the hardware

NVIDIA NVIDIA 6000 - RTX PRO 6000 BLACKWELL WORKSTATION EDITION — the exact model, not the family. Partner boards differ.

Mount it dry

Thermal interface material as supplied. Even mounting pressure, correct bracket orientation, no over-torquing.

Leak test before power

Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.

Questions people ask about this part

Answers specific to N-RTXPRO6000-WS-SR. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

What does this part fit?

It is machined for NVIDIA NVIDIA 6000 - RTX PRO 6000 BLACKWELL WORKSTATION EDITION. Bykski cut these to a specific hardware layout, so confirm the exact model rather than the family before ordering. Part number N-RTXPRO6000-WS-SR.

Is it in stock, and when will it ship?

Yes — in stock in Boise, Idaho. Orders placed before 2:00 PM MST on a business day ship the same day — we do not ship weekends or US holidays. Overnight delivery is available at checkout.

Can I return it if it turns out not to fit?

Yes. Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used. So we would rather check the fit with you first: send us the model and we will check it against this part.

Will I pay import duties or customs charges on delivery?

Not on a US order. US import duties and tariffs are already included in the price, so nothing is collected at the door and there is no brokerage fee. Orders shipped outside the US may owe that country's customs fees and duties.

Who handles the warranty?

BYKSKI.US, the exclusive US distributor, from Boise, Idaho. Claims are handled domestically rather than returned to an overseas factory. Installation is at your own risk: we are not responsible for leaks or damage to other hardware.

Is shipping free?

Yes — shipping is included at this price for addresses in the lower 48 US states.

Are printed instructions included?

No printed manual is included. Installation references are in the product gallery images, and the install guides on this site cover the process step by step.

Do I need anything else to use it?

A water block is one component of a loop: you also need a pump, a radiator, fittings, tubing and coolant. If you are starting from nothing, an AIO or a distro-plate kit is the shorter route — ask and we will spec it.
