First, let’s move back to the aesthetics of the cooler. Most AIO/CL Liquid CPU Coolers we have seen pop up in the recent years, all tend to have the same look. We are pleased to see that Cooler Master took the extra steps to make the base design of the cooler a little different. While most of the radiators designed are very similar, Cooler Master’s Fin design helps reduce noise and also air restrictions. The Radiator completed the look with a nice black finish keeping the entire cooler looking uniform and sleek. The tubing used on the Cooler Master Seidon 120M reminds us of the Corsair units we have seen in past units. The flexible hard plastic tubing was easy to maneuver for installation and we had no problems to report here.

Moving to the base (pump/block) it was nice to see that Cooler Master moved away from the typical plain black base we normally see with the AIO coolers. The LED was especially appreciated for the additional aesthetics appeal and function. While we are on this subject, the pump is powered by a 3 pin fan type header which is also sleeved to keep the look consistent with the rest of the cooler. Although we didn’t run into any problems with the pump we did feel that the pump was a little on the loud side. While loud may not be the 100% correct term we noticed, we should say it was more of a ticking noise coming from the pump that was audible even with the fan on. However, once under load and the PWM fan picked up more speed we didn’t hear it as much. Now don’t let that discount from this cooler as we find this to be a similar complaint with most AIO coolers available in today’s market.

In the thermal performance sector of the cooler we feel that it did great on both our Intel and AMD platforms. Most users today are looking to use these cooler to assist in overclock settings and we feel that the Cooler Master Seidon 120M did very well. The cooler was designed to be compact and maintenance free, which Cooler Master hits on every mark. You can mount this cooler in any case that can accept a 120mm fan. We also feel that if you are looking for that additional thermal performance you can purchase an additional Cooler Master fan and use a push/pull configuration to give it a nice final touch.

Our impressions with the Cooler Master Seidon 120M Liquid CPU Cooler gives it an honorable Great Hardware Award. While this unit was priced at $69.99 on newegg at the time of the review we feel this unit gives the users great bang for your buck.
