Montech TG3 Case Review: Budget Winner

It has been a year since we first saw the budget TG3 on show at Computex 2025 and we have finally got our hands on a sample for review. The main components are a unibody 360mm fan in the side of the case with two glass panels and RGB lighting galore. The shock is that this case is remarkably cheap, but despite that it is solidly built and offers decent quality.

Testing

To put this case through its cooling paces we will be using a test system consisting of an AMD Ryzen 7 9850X3D, Sapphire Nitro+ X870EA PhantomLink motherboard and an SSD. This system allows us to produce a substantial amount of heat and effectively test the Montech TG3‘s cooling capabilities.

Test System:
Processor: AMD Ryzen 7 9850X3D
CPU Cooler: Montech NX600
Motherboard: Sapphire Nitro+ X870EA PhantomLink Polar Edition
Memory: 32GB Kingston Fury Beast DDR5-6000
Graphics card: Sapphire Nitro+ Radeon RX 9070 XT 16GB
Power supply: Montech Century II Gold 1050
SSD: Crucial T705 Gen 5 M.2 NVMe
OS: Windows 11

Cooling Performance

Cooling Performance Overview

We stressed the Montech TG3 with a combination of Speedway Stress test and Cinebench R23 that drew 560W-580W at the wall socket. Our Sapphire RX 9070 XT graphics card was nice and cool under full load while the AMD Ryzen 7 9850X3D was slightly warmer than we wanted.

Closing Thoughts

The Montech TG3 uses a layout that follows the same conventions as a great many other ATX tower cases. You have glass on the front and main panels, with cooling air drawn in from the right hand side through 3x 120mm fans. Inside the main compartment the power supply shroud stops short of those side fans to give you the full benefit of the ARGB light show.

In other words there is nothing about the TG3 that is unusual, and the only curiosity are those side fans that use a unibody design to tidy up the cabling and reduce the number of installation screws.

This makes it quite amazing to us that Montech has managed to launch the TG3 at a mere £49.99 in the UK and we understand that will be $59.99 in the USA.

You can buy the Montech TG3 for £49.99 HERE.

Pros:

• Very low price.
• Good amount of room in the main chamber to assemble your PC.
• Decent build quality.

Cons:

• The cooling is nothing special.
• When you crank up the fans the TG3 gets noisy.
• The main components are riveted together.

KitGuru Says: The Montech TG3 is a decent case at a crazy low price.
