Cooler Master Seidon 240V AIO CPU Cooler Review

Introduction

Cooler Master have some of the best and most popular coolers on the market, from their iconic 212 air cooler to their MasterLiquid series, they’ve got a little something for the everyone. Now they’re throwing their engineering skill to the budget AIO water cooling market, as we take a look at their brand new Seidon 240V.

“The Seidon 240V is the latest AIO watercooler that boasts an excellent value for performance. The compact 240mm radiator fits in virtually every case. Thanks to dual Silencio fans designed for silence, Seidon can unleash a powerful cooling storm at your command and keep it silent. Durable FEP Tubing provides the advantages of nearly no moisture absorption, high thermal stability and high pressure tolerance which all contribute to a long operating life.” – Cooler Master

The Seidon 240V looks to tick all the boxes for a simple yet effective AIO water cooler, with a slim radiator that ensures high compatibility with chassis designs, a compact and low-profile pump to prevent motherboard conflicts, slim and super flexible tubing, silent fans and hopefully some robust cooling performance.

The packaging is pretty simple, with a nice image of the cooler as well as all the usual details on the front.

Around the back, just a few basics about the radiator and pump dimensions, with the full specifications on the side of the box also.

The packaging is nicely laid out, with all major components nicely protected.

In the box, you’ll find a universal backplate, Intel and AMD retention brackets, all the usual thumbscrews and bolts, thermal paste, and a Y-split fan cable. What I do like is that there is eight extra fan screws, handy if you ever want to install push-pull fans.
