MSI Ventus 2X 4070 Super Deshroud Guide

The primary challenge in deshrouding the MSI Ventus 4070 series GPU lies in removing the PCI bracket without separating the heatsink from the mainboard. This guide will walk you through the process step by step.

Required Tools

To start, ensure you have a small precision screwdriver with a thin neck, ideally magnetic-tipped, PH00, with a shaft length exceeding 4 cm and a diameter no more than 2.5mm. Avoid screwdriver types with interchangeable tips, as their bulky tips may hinder maneuverability in tight spaces around the GPU.

Step 1: Remove the PCI Bracket

The objective is to remove the PCI bracket, making it easier to access screws securing the shroud. Begin by removing the three screws on the PCI bracket, circled in green.

Step 2: Access the Hidden Screw

After removing these screws, you'll need to unscrew the one towards the bottom left.

Locate and remove the screw hidden between the PCI bracket and the shroud. It is important that you use a screwdriver with a thin shaft for accessibility. Once removed, the metal PCI bracket should detach.

Step 3: Remove Side-Mounted Screws

With the PCI bracket removed, pivot the metal bracket to access the first of four side mounted screws securing the shroud to the heatsink. Use your precision screwdriver to carefully remove each screw.

Step 4: Remove Remaining Screws

Proceed to remove the remaining three screws around the heatsink's edges. Disconnect the fan cable from the GPU board.

Step 5: Install the Bracket and Fans

Once all screws and the fan cable are detached, carefully lift the shroud away from the heatsink. You do not need to unscrew the stock fans. Guide the bracket's tabs into the four open slots in the heatsink fins with caution. Then, securely fasten the four screws on the side of the heatsink to ensure the bracket is firmly secured in place.

Install your two 120mm fans, securing them with the provided M4 screws. Connect the fan headers into the Y cable and plug the Y cable into the micro fan port on the GPU board, completing the deshrouding process.

Software Setup

If you are using MSI's Afterburner software, I find that the default fan curve is optimal for both performance/noise when using a pair of Noctua NF-A12 fans.

  1. Access the Settings menu in Afterburner (white arrow)

  2. Click on the Fan tab, click Enable user defined software automatic fan control, select Default and then click Apply

Note about the Y-cable: You may notice that one of the pins in the male header of the Y adapter cable is "missing." This is by design. The missing pin ensures that only one fan reports its RPM signal to prevent conflicts when multiple fans are connected to the same header.

Please feel free to message me on Etsy if you have any issues with the install. There can occasionally be differences in mounting holes among different revisions of the same GPU model. If this is the case, please reach out to me and I will help you right away.
