Tools of the trade: I upgraded my gaming PC with a 420mm Arctic Liquid Freezer 3 AiO and vertical GPU mount, and now it looks incredible

With Battlefield 6 on the horizon – plus plenty of Borderlands 4, MechWarrior 5: Mercenaries and Hades 2 to play – I wanted to upgrade my AMD Ryzen 7 9800X3D and RTX 4090 Founders Edition gaming PC to better cope with these demanding titles.

The goal here is to improve temperatures, reduce fan noise and make things look a little nicer, so I’ll be swapping the (admittedly chonky) 240mm AiO liquid cooler I currently have installed for a massive 420mm unit from Arctic. With more surface area and larger fans, I should be able to run the fans at lower speeds while still achieving much better cooling performance in these and other CPU-heavy games.

I set aside Friday morning to make the swap, and the results exceeded my expectations. I’ll share what I learned, why I made the choices I did, and also discuss the titanic Havn HS 420 VGPU case that I’ve been using for the past six months.

Part one: Arctic Liquid Freezer 3 Pro RGB install and mini review

I’ve been relatively happy with the Hyte Thicc Q60 240mm AiO CPU cooler I’ve been using for the past few months, with its pleasant black/white colour scheme and surprisingly good thermal performance for its size, but it does have some flaws. First, the display screen attached to the CPU block made it impossible for me to vertically mount my graphics card, as it hung down too far below the CPU socket.
