Hey all!
About 6 months ago I designed a fan shroud that can be installed in your Lenovo M720q (and m920q) with a 10/25G network card that will significantly drop the temperatures of the card. In my cluster, I got a 44C temperature drop under 100% load with the CPU also at 100% load, just to make it worse case scenario.

If you'd like to print off and order the parts yourself, the bill of materials and STLs are available here:
For those that want a kit or a plug and play USB version, I've got some for sale!
You can find pictures of the USB version here
For kit assembly instructions and temperature results, they are available on the Printables link above. And for the USB version, it's a simple plug and play with no soldering required.
The only real requirement to use this, is you must have a 40mm space between the heat sink of your network card and the front of the case. These work great on my Fujitsu D2755-A11 GS3 cards, which I think is a rebranded Intel X520-DA2. I've had comments on my Printables page saying it works great on a SuperMicro AOC-STGN-I2S and Mellanox MCX314A-BCCT.
The shrouds are printed in Voxel PETG+, just in case you all are running your rigs hot for whatever reason. I'm personally using PLA+, haven't had an issue, but just being extra cautious.
What you get:
USB Version:
- Fan shroud printed in PETG+
- Dual ball bearing 40mm blower fan modified to work with USB port for power
Kit Version:
- Fan shroud printed in PETG+
- Dual ball bearing 40mm blower fan with a 2 pin JST XH 2.54 plug
- Two styles of JST 2.54 male plugs that will need soldered to the 5v pad on the board
OPTIONAL:
If you'd like me to print off a [PCIe Bracket/Baffle designed by Simbaja](https://www.thingiverse.com/thing:4816134), let me know, I'll include it for free. I don't want to profit on his awesome design, just want to include it if you need it. The notched version for the USB, and the regular bracket for the kit.
I also have A/E key to M.2 adapter boards for $3 that can be added to the order, this allows you to replace the WiFi chip with a 2230 NVMe SSD. I personally use the SK Hynix models on Amazon for $16 a piece. Easy way for you to offload your OS to a cheaper smaller SSD, and use the larger NVMe on the bottom of the device for shared storage in a cluster, or NAS.
Pricing:
USB Version:
- $20 per shroud or $50 for three
Kit Version:
- $15 per shroud or $37.50 for three
Shipping will be $8.50 via USPS
Payment will be PayPal
If you have any questions, feel free to ask!
TL;DR
Selling 3D printed fan shrouds with a 40mm blower fan that can reduce the temp of your 10/25G network cards by almost HALF.
