Thermaltake TH420 V2 ARGB Sync AIO Cooler

A Closer Look

The fans are nice enough, basically their CT140 ARGB fans in black, which is great, as they’ll match up with the fans used in current Thermaltake cases and more can be purchased separately to match. Check out my review of these fans here!

There are three in the box, and each comes with a 5v ARGB header, as well as a 4-pin PWM header, ready to be hooked up to your motherboard or controller of choice.

As for the radiator, well, it looks pretty much as you might expect really. It’s a slim radiator design, so compatibility will be great, and you can mount the fans on either the front or the back to suit your needs. However, this being a slim radiator, two layers of fans aren’t really needed. The larger 420mm radiator design is obviously only going to fit in the larger PC cases on the market, so be sure it is supported before you order.

The pump is really nicely done too, quite slim, so it’s not going to overrun or conflict with motherboard components, and there’s a nice two-tone finish to the top I really like. There’s a reflective top plate, with a built-in ARGB logo, which you’ll see in action in a moment.

On the underside, there is a nice large copper contact plate, so it’ll provide good coverage even on the larger CPUs that it supports.

The fans and radiators make for quite a site, a very large combo here, and the largest AIO I’ve ever tested!
