Cooler Master delivers water cooling for the masses

We’ve said it on KitGuru a number of times: If you were boiling hot on a summer’s day and had the choice between (a) sitting in a small, dark room with a fan on you or (b) diving into a swimming pool, then we all know which one cools best. But then there’s price. Cooler Master’s latest offering is aimed at making ‘swimming pools’ much more affordable.

KitGuru dons the Speedos and hopes the ‘S’ does not fall off.


The stock coolers that arrive on an Intel or AMD processor are OK. They will work if you never do anything exciting.

Apply a small overclock (i.e. quick fiddle with the BIOS), and there are a number of companies out there with solutions in the sub£20 range which can do a decent job.

Next you come to overclocks that require a little voltage tweak. Now your better air coolers come into play and you could be spending up to £50 for a solution.

Lastly, you have the extreme crew: Folks that love to torture their processor to the point where they can squeeze every last iota of performance. Now you’re in the land of the serious air coolers – with products costing anything up to £75.

The name ‘Cooler Master’ indicates a master of cooling. Ironically, Cooler Master has become much more famous for its power supplies and chassis over the last couple of years.

With the launch of the Seidon 120M water cooler at £45, the company is hoping to get back to winning ways inside your chassis.

Neat design looks cool inside your chassis - but we'll need KitGuru Labs data to confirm just how cool

As you would expect, it is 100% compatible with all leading CPUs and the PWM fan can run anywhere from 600 to 2,400 RPM – according to your load – with a corresponding noise level of 19-40 dBA, which means that the 17 dBA from the pump will, effectively, be completely silent.

It only draws 3.6w, but aims to dissipate a huge amount of heat from your overclocked CPU. The 120mm fan and low unit height, means that it is compatible with most chassis/system configurations.  The fan itself can push anywhere from 19 to 86 cubic feet of air per minute, with a variance of around 10%.

The familiar face of pre-filled watercooling systems

Use a case like the Silencio, with the fans turned down, and you have the basis for a very quite monster rig


KitGuru says: When you consider how iconic chassis like the Cosmos are, it’s always a little surprising that Cooler Master is not more popular in the CPU chilling market. It hopes to change that with the economically priced Seidon 120M – let’s hope they succeed.
