## Overview

The Barrow Copper GPU Water Cooling Block is a precision-engineered cooling solution tailored for the MSI RTX 5090 Ventus 3X series. Featuring a thick CNC-machined copper base with mirror nickel plating, it delivers exceptional heat absorption and transfer. Its innovative triple-layer cold finger core and 43 micro-channel water passages maximize cooling efficiency, while the high-transparency acrylic housing enhances durability and showcases vibrant LED lighting. Designed to reduce GPU load and protect vital components, this waterblock ensures stable overclocking and superior thermal management for demanding gaming and professional workloads.

## Description

The purest copper back plate fully cover high heating components such as GPU core,memory RAM,power chip NOS,tantalum capatitors and so on.Through liquid flow take away the heat that is conducted to the water block to achieve cooling purpose,which make sure players could have a good game experience and the PC remain stable overclocking performance. The 10mm super thick copper raw material is made by CNC processing.The material is solid.The surface is treated with anti-oxidation nickel plating,which extends the service life .Thanks to the material used for thickening plate.This realizes the single-layer sealing structure and increases the water flow coverage area.It not only improves the sealing stability of GPU ,but also is more conducive to evenly absorb and conduct the heat of each heating part of GPU . With the weight reducing structure design,the weight of the product is reduced,and the load-bearing load of GPU is obviously reduced. The backoard takes into account the video memory of the back,providing all aspects of protection to the GPU,bringing a strong appearance and strong cooling performance to the GPU. The size of the backboard is close to the length of the GPU PCB,leaving more space inside the chassis to expand other hardware.

Review: It fits and works. I would advise getting your own thermal pads and doing test fitting to make sure everything stays cool. The provided pads never made contact when I had everything put together.
Review: To start the customer service with ordering this block helped a lot. When I had asked about fitment with my card they wrote back the next day and just needed a picture of the board without the air cooler to ensure that it would fit. Once the block arrived I started the process of installing the block. The instructions with this waterblock are lacking, More detailed instructions with what screws fit where would have helped along with detailed pictures. The other part of this the bracket for the IO, there needs to be improvement in making it smaller. The directions and markings of the thermal pads for between the front of the board and the waterblock need to be better. I was able to figure this out but I could see it being an issue for someone who has not done this before. The last part of the installation that is a problem is the backplate. There is no contact with the back of the PCB. This caused problems with the heat, especially with the power connection. This has a lot of heat that it produces and I know can cause cables and the board to melt. I took a 3mm thick thermal pad I had and placed it between the backplate and the back of the board where the power connects. This did help with heat in the cable. The performance of the block itself has been good but not great. The difference between max high temps on the air cooler and the waterblock are 20°C. Also the card now idles around 25°C. So it is making a difference but the fact that I am still getting a high temp under stress tests of 52-54°C, which is higher then I would expect for having a 120x480mm, 120x120mm and 140x280mm rads to cool the card. Overall for the price and the help I have received in getting the card I would recommend this but if you are going for max performance I would look else where. Should I start to have any issues with the card I will come back and charge my rating. Good waterblock, worked for what I needed and the customer service was a big plus.

## Features

- 1.GPU core,memory RAM, power supply chip MOS,inductance and tantalum capatitance,other components with high heat output.
- 2.Three layer cooling design of cold finger core,coolant can absorb calories of GPU core cooling more strongly and improve cooling efficiency.
- 3.High-temperature-resistant and high-transparency imported acrylic raw materials have higher transparency,longer life,no color change,no cracking,and emitting full of internal brilliant lighting effects.
- 4.The enlarged area of water passage has as many as 43 micro-channels,each with bottom-clearing slots and 5+3(0.5mm groove width+0.3mm interval)asymmetric water channels.The contact crea between the water cooling liquid and the soleplate is increased,as well as the heat dissipation efficiency of the cold head is enhanced.
- 5.As the main material of the soleplate,copper with thermal conductivity which is less than silver,has high heat absorption and heat transfer efficiency.The surface adopts the mirror nickel plating process,which can effectively prevent the soleplate from oxidation and increase the service life.

Fits on my Gaming trio, Kinda sucks that I needed to use the original mounting bracket thought. It is really hard to get on.
