Today we are going to be looking at a new AIO/CL CPU Liquid Cooler unit. Just in case you don’t know these term’s AIO stands for “All in One” and “CL” for “Closed Loop.” These conventions have become rather popular over the last few years in the PC world. With the latest technology advancements in water cooling, it has become much easier for consumers to water cool their PCs with these AIO CPU Liquid Cooling units. The design takes the guess work out. With water cooling kits in the past, it could take countless hours of planning, and assembly could become a headache for those that have no experience. However, recently we have seen a change with the new trend in water cooling. We have started to see these AIO and CL coolers show up from several manufactures. Today we are going to take a look at a new-comer in the AIO CPU Liquid Cooler field. It is a device from Cooler Master called the Seidon 240M Liquid CPU Cooler.

Closer Look:
The Cooler Master Seidon 240M comes in a black box with purple accents Cooler Master’s 20th anniversary colors. Overall the effect is good. On the front you have a large picture of the Seidon’s itself. The head is there to make sure you know that you are not getting another Asetek rebrand with the Seidon, but are getting something new.
On the back of the box, as if to enhance the impression that this is Cooler Master’s own design there is a technical drawing and specifications laid out as if you were looking at the original designs. It is a subtle but impressive effect.
Once we have the package open you can see that they have everything packed nicely, which ensures that the unit will not get damaged during transport.
Here is the included hardware that is packaged with the Seidon 240M, we have two 120mm PWM fans, Intel mounting plate with screws, AMD and Intel installation hardware and we have the warranty and instruction manual.
Taking a closer look at the Cooler Master Seidon 240Mm Liquid CPU cooler we see the 240mm radiator. The radiator is constructed of aluminum and is completed with a nice coat of black paint for its final touches. The finish of the radiator really looks great. Looking at the radiator fins, we find the radiators fins were placed with precision to assist in cooling and heat dissipation. The fins were also finished with a thin coat of black paint to keep that nice sleek look. The Fin design is also optimized for minimum air restriction to reduce fan speed and noise.
Moving to the cooling block and pump of the Seidon 240M CPU Cooler, you can see that Cooler Master has made some unique design touches. Cooler Master uses its “Precision machined Micro Channels” maximize the water contact surface to quickly dissipate heat on its water block. Keeping the fluid flow from the radiator to block, they have used hardened plastic tubing that is flexible and easy to maneuver for installation.
Taking a look at the base here, they have the waterblock machined out of a single block of copper to create the best possible heat transfer with its micro channel design. The block is also secured together using 12 stainless steal bolts. The base is not a mirror finish, but the cooper is smooth and even. In our picture it looks as if the cooler has very fine scratches, but this is actually just a brushed finish look.

Conclusion:
The Cooler Master Seidon 240M Liquid CPU Cooler delivered excellent cooling performance under all conditions, the best I have seen from an AIO 240mm solution to date. I also like the fact that cooler master manufactured it themselves and didn’t use the same OEM pieces that we have seen before. In Cooler Master fashion, they took their own route and came out with something decidedly different.
The assembly of the hardware was pretty straight forward and simple. There is one thing that was quite obviously wrong in my mind with it, though. The risers always seemed to back out with the hardware and not stay in place well at all when tightened as good as I could get them. I think a rubber washer instead of plastic would quickly solve this issue. The Cooler Master Seidon 240M Liquid CPU Cooler is priced at $104.95 and can also be found cheaper at some retailers and is worth every penny.
