Supermicro Xeon D / FCBGA 1667 Heatsink information

So I tried a few different things for 1U with my 1541 just using some card stock and the noctuas. Having two pull air through the heatsink with a cardstock shroud still brought the CPU up to 90C under heavy loads.

3 fans and a cardstock duct finally had enough airflow to cap loads out at 80C.

Good to know! I actually have exactly the same case as you, but it's used as a firewall not a NAS, so just have a PCIE network card in the riser on the left.

What made you decide 90 was too high? Not enough headroom for comfort? The chip is rated to 108C but I noticed it issues a system warning at 102C.

I change D1521 to D1581(x10sdv-4c-tln2f), cost about $30. using Thermalright AXP120. It works perfectly. idles at 40c

did you use a customized back plate? I bought a axp120 butit doesn’t look like yours. Thanks!

Hey folks,

Has anyone here had experience using a budget-friendly low to mid-range heatsink? I'm considering options like the Cooler Master Hyper 411R, Thermalright Assassin X 90 SE, Amazon Basic CPU Cooler, Arctic Freezer 7X, etc.

I saw this Thermalright AXP120, but I was wondering about a single-tower one:

Any insights or recommendations would be appreciated, thanks!

Hi guys, any good 2U options left on the market?I can't find the BUF-E anywhere.

Hey folks,
I've created a 3D printable adapter that allows you to use the Amazon Basics heatsink on Asrock Rack D15XXD4I motherboards (e.g., D1521D4I, D1520D4I, etc.). This adapter lets you reuse the original heatsink screws with their springs.

I hope it will be as useful for you as it has been for me!

The Amazon heatsink is asymmetrical, meaning one part covers the screws used to secure the adapter. The adapter features a rounded end and an angled end. The angled part should face outward, while the rounded part goes inward.

Mounting instructions:

1. Print two copies of the adapter.
2. Install the first copy without the heatsink, as the heatsink would cover the screw points.
3. Apply thermal paste to the CPU.
4. Slide the heatsink slightly at an angle to fit under the secured adapter.
5. Place the second copy of the adapter on the opposite side and tighten the screws.

Since switching to this heatsink, my idle temperatures have dropped from 49°C to 36°C. I printed the adapter using MJF PA12 (nylon) for enhanced mechanical strength. I’ve added sponge bumpers on the underside of the adapter to prevent minimal shifting due to tolerances.

You can find the adapter design here.

Here’s a photo of the installed heatsink:
