Transform your dual-slot Arc Pro B50 into a true single-slot, low-profile card. Precision skived and CNC-milled from solid copper with a stainless steel shroud, this thermal solution replaces the factory cooler, enabling high-efficiency workstation graphics, media encoding, and AI compute in tight chassis like the Minisforum MS-01/MS-A2, Lenovo ThinkCentre Tiny, and dense 1U server racks.

Warning for Linux users

The Linux Arc drivers do not expose the fan PWM control to the OS. This means that the fan will always use the stock curve and is not modifiable. The stock curve is too slow for the fan on this cooler, resulting in overheating on sustained full load. There are a few solutions:

Use the motherboard adapter to drive the fan from your motherboard.
Minisforum MS-01 and MS-A2 users can use the MS-01/MS-A2 set to use the NVME2 fan header.
Minisforum N5 users can use the N5 adapter to use the PCIE FAN header.

Maximum GPU density

This custom cooling solution transforms your dual-slot Intel Arc Pro B50 into a true single-slot, low-profile powerhouse. The cooler enables high-efficiency workstation graphics, media encoding, and AI compute in the tightest SFF builds, 1U server chassis, and high-density homelabs. It features a full copper skived baseplate and finstack with a stainless steel shroud.

Unmatched GPU density: Converts dual-slot cards into a true single-slot form factor to double your compute capacity.
100% pure copper heatsink: Skived and CNC-machined for optimal thermal dissipation under heavy workloads.
Easy drop-in replacement: Precision-engineered to fit the original PCB for a seamless and hassle-free conversion.

easy to install, si didnt have to adjust the fan curve as my install is in a 1u server, it does fit into a Halfheight/Half length slot, really love this. media server is doing really well with the b50 transcoding. thank you!

In a space constrained setup, you’re obviously very limited on the GPUs you can use. These n3rdware coolers expand those options considerably. The B50 cooler is SUPER high quality it looks awesome, it runs cool, and my UGreen NAS is now a powerhouse!! I’m a very happy customer! Thanks Robbe for such a great product!

I purchased the Minisforum N5 Pro AI mainly for running local LLMs, and after replacing the original cooler with this one, the temperatures improved significantly. I’m very satisfied with the cooling performance overall.

One small suggestion: although the included thermal pads were pre-cut, they were a bit difficult to peel apart cleanly, so I ended up trimming them manually during installation. It would be great if this could be improved in future revisions.

Overall, I’m extremely satisfied 🥳
