Cooler Master is known in the enthusiast community for their innovative designs with product offerings ranging from cases to desktop and laptop cooling implements. Like many other manufacturers, Cooler Master offers its own line of all-in-one liquid cooling solutions. Unique to their Glacer 240L cooler is the ability to easily add additional cooling blocks into the base loop. The Glacer 240L has an fill port integrated into the base of the radiator for drain and refill and uses removable clamps on all connections for easy maintenance and tube reconfiguration. To measure the performance of the Glacer 240L, we set it against several other high-performance liquid and air-based coolers. With a $139.99 MSRP, the Glacer 240L comes at a premium price.

The Glacer 240L liquid cooler features a 240mm copper-finned radiator with the ability to add additional water blocks into the loop. Cooler Master dubbed this design "Semi-DIY" because is can be used as a high performance all-in-one liquid cooler or expanded to include other water cooling components in your system. They combined a 25mm wide 240x120mm copper radiator (with brass internal channels) and copper waterblock based in an acrylic housing for the pump and unit electronics. By using a copper/brass radiator and a copper CPU block, Cooler Master avoids the mixed-metal issue that most of the other all-in-one units are plagued with by using cheaper aluminum-based radiators. All barbs integrated into the radiator and CPU block are 90 degree barbs with full 360 degree rotation, allowing for unparalleled mounting configuration possibilities.

Cooler Master bundles in mounting hardware supporting all current Intel and AMD processors, as well as screws for attaching additional fans to the backside of the unit or for attaching it directly to a system case wall.

Will you be testing this unit with an expanded loop say a gpu block? It seems to be the main selling point of the unit and any word on the 360l?

We are planning on testing this unit in the near future in conjunction with gpu block...

Awesome!

Isn't this a rebranded swiftech h220 with a more powerful pump

I thought the same thing... :/

You both might very well be correct in that.  Thanks for pointing that out...

It's just the plastic cover on top of the pump that's different, otherwise it is the same. The pump in the CM version is allowed a little higher RPM, as it has a separate power connector. The original version had only a 4-pin fan connector. People connected this to voltage-controlled fan-ports, dealing damage the pump electronics. It was stated very clearly in the instructions not to do this, but people being people...

My Swiftech H220 also came with a 8-way PWM splitter/adapter, also stated quite clearly in the instructions that always using the adapter was the preferred method. I have had my H220 in a 2011-system now for almost a year, running very close to 24/7.

The Swiftech Helix fans are quite nice, I think they are quieter at the same airflow compared to the CM ones, but I have yet to see real tests comparing them. Martin's Liquid Lab has tested the Helix fans, they were not as good as the all time high Gentle Typhoon AP-15 though.

Still sticking with the Corsair H100i CLC, nevertheless great Review.

How powerful is the pump, for example, can it handle an additional 120mm radiator and a GPU block, so that the fluid leaving the CPU block can be cooled by the 120mm radiator before going to the GPU?

As this is a rebranded Swiftech H220, it can handle additional radiators with no problem. Another 240mm radiator is no problem.

Edit: Martin measure a 0.6 GPM flow rate in his H220 review. He comments on this as a problem when bleeding the loop, the CM version should have a little higher flow rate (~500 more rpm on the pump) making it a bit easier to bleed when expanding the loop.

Martin's review: http://martinsliquidlab.org/2013/01/27/swiftech-h220-prefilled-2x120mm-w...

Very impressive "living" review that starts in jan 2013 and the last updates are in may 2013. He also follows a couple of forum threads and talks about the problems of batch 1 (mine is one of those). You can't compete with this guy :D
