The Cooler Master Glacer 240L liquid cooler performs on par with the top-rated coolers that we've tested with its performance increased by adding two fans to its stock configuration. Cooler Master did their best to ensure that the cooler liquid flow was minimally restricted with their selection of 3/8" inner diameter tubing to connect the CPU block and radiator.
As of March 15, the Cooler Master Glacer 240L liquid CPU cooler was available at Newegg.com for $139.99 with free shipping, as well as Amazon.com for $139.99 with Prime shipping and Performance-PCs.com for $139.99.
Before continuing with our parting sentiments on the Glacer 240L liquid cooler, we would like to take this opportunity to give our friends at Cooler Master a hearty "Thank You" for giving us the pleasure and opportunity to review such a high quality and well-designed cooler. When selecting a liquid cooler for your system, there are several areas of concern on which to focus – the radiator size, thickness, and fin density; the water block construction and base plate quality; and the barb and tubing sizes used to transport the medium within the cooler. In designing the Glacer 240L, Cooler Master built a cooling system capable of handling its stock configuration heat load with a CPU block only, in addition to the heat load introduced by add-on cooling blocks. Cooler Master used a copper-finned radiator with brass liquid channels as well as a copper block to ensure optimal heat transfer to and from the liquid transport medium. Additionally, use of similar metals in its construction ensures that the cooler will have minimal risk of galvanic corrosion.
The tubing used to connect the radiator to the CPU block was 3/8" inner diameter tubing with a 5/8" outer diameter, ensuring that liquid flow was not constricted by the tubing and that the tubing was capable of a tight bend radius. The 90 degree barbs used on the unit were designed with a full 360 degree freedom of rotation, ensuring that the radiator and block could be mounted in just about any case configuration or orientation. The biggest innovation was the inclusion of an easily accessible drain port in the front bottom collection chamber of the radiator. The metal plug sits in a standard G 1/4" port, ensuring its compatibility with a wide range of after-market drain and fill adapters. Further, the drain port allows for easy expandability of the loop. The tubing itself is held in place with screw clamps that are also removable for tubing and flow reconfiguration, necessitated by the addition of new blocks to the loop. Performance-wise, the cooler was virtually unmatched by its competitors with potential evident in the benchmarking results to handle an increased heat load from add-on blocks.
As far as design deficiencies, there were a few minor items that may have inhibited performance of the cooler. The most obvious challenge was with the placement and size of the barbs used on the CPU block. The CPU barbs stuck out a bit past the mounting arms for the Intel processors, causing mounting issues with the block in certain orientations. The block would fit and sit flush on the processor, but it became a matter of finding the correct block orientation so that the barbs did not rest atop the surrounding CPU VRM heat sinks. The other concern was with the low FPI density of the copper radiator. Its low FPI density did not appear to inhibit the unit's cooling performance at all. However, a higher FPI density would have increased the radiator's cooling ability with minimal impact on airflow through the radiator because of the high pressure fans bundled with the unit.
- Performance under stock and overclocking conditions
- Build and machining quality of the cooler
- Copper radiator
- All copper loop construction -> no mixed metals in loop
- CPU block and radiator barb rotational freedom
- Tubing size and inner diameter -> 3/8" x 5/8"
- Lack of DIY information in manual for adding components to loop
- Low FPI density on radiator
- Horizontal width of CPU block
Will you be testing this unit
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
We are planning on testing this unit in the near future in conjunction with gpu block…

You both might very well be correct in that. Thanks for pointing that out…
It’s just the plastic cover
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
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
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.

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 😀
Can you address the issues
Can you address the issues regarding the slew of users reporting fires caused by their Cooler Master 240L? These typically occur withing a few weeks of installation. I just bought one recently and I am seriously concerned about possibly burning my house down. I have seen many, many reports of these fires.
Great review! Any news on the
Great review! Any news on the expanded (CPU+GPU) review?
I’m also interested in the pump failure / catching fire problem that many people seem to be having with this cooler, several can be read on Newegg and watercooling forums… Any insight on this?
