Testing Participants

Corsair Hydro H55 Quiet

The junior model among the four Corsair products we’re going to test comes under the name of Hydro H55 Quiet. It is packed into a small cardboard box which is mostly white in color:

The cooler’s photo and model number can be seen on the front of the box. Its specifications and accessories are listed on the sides.

 

You can also find a list of supported platforms and diagrams comparing the cooler’s efficiency and noise level with those of an Intel boxed cooler.

There’s a soft cardboard box inside the external one. It has compartments for the cooler, fan, and accessories.

The accessories include retention and back plates, screws, plastic locks and metallic bushings – everything you need to install the Corsair Hydro H55 Quiet on any of the supported platforms. You also get some documentation:

The product is manufactured in China and costs $69.95. The warranty period is as long as 5 years.

Like the majority of the products covered in this review, the Corsair Hydro H55 Quiet is based on the popular Asetek 550LC platform which is inexpensive and easy to install and use. We first met this platform about 2 years ago in our review of the Antec KÜHLER H2O 620 and it hasn’t changed since. It still consists is a radiator with fan, two flexible pipes and a pump/waterblock combo:

The pipes are 300 mm long and have an outer diameter of 11 mm. They are squeezed tight by the input and output fittings, giving us no cause to worry about the reliability of these connections.

The aluminum radiator consists of eleven 1.5mm flat pipes with a corrugated ribbon in between.

The body of the radiator is only 17mm thick while its total thickness is 27 mm. There are threaded holes on both sides of the radiator for M4 screws to fasten fans. The overall dimensions of the radiator are 152x120x27 mm.

A sticker on one side shows a barcode and a power rating which is 3.9 watts.

Two nozzles for pipes stick out of the radiator on the other side:

The pump/waterblock unit on the other end of the pipes measures Ø72x28 mm.

Its performance is not specified (just like the performance of the other pumps in this review). It is connected to a mainboard’s 3-pin fan connector so we could easily measure its power consumption. We were surprised to find that this parameter varied between the coolers although 4 out of the 5 pumps were in fact identical. The pump of the Corsair Hydro H55 Quiet consumes 2.14 watts.

The pump/waterblock unit weighs about 220 grams. Its ceramic bearing is expected to serve for at least 50,000 hours and its noise level is within 26 to 37 dBA. That’s all the information we could get about it, though. “High-efficiency thermal interface” of obscure origin is pre-applied on the copper base of the waterblock:

The waterblock itself is hardly impressive in design. It features a microchannel structure with slim copper fins that are 6-7 mm in height.

This simple solution is actually quite efficient as we already know. The fittings can be turned around to make it easier to install the waterblock on the CPU and lay out the pipes inside the computer case.

The waterblock’s sole is finished well and has no irregularities like some air coolers. The thermal grease imprint on the CPU's heat-spreader is quite normal, even though not ideal:

 

The Corsair Hydro H55 Quiet is equipped with one 120mm fan that has a black frame and a glossy black impeller with seven sharp blades:

 

The fan has no speed regulation and rotates at a constant 1700 RPM. Its air flow is specified at 57 CFM and its noise, at 30.3 dBA. The service life of its sleeve bearing is 50,000 hours.

Like the other coolers in this test session, the Corsair Hydro H55 Quiet is compatible with all modern platforms from both Intel and AMD. You use the same retention frame to install the waterblock irrespective of your CPU:

First you insert plastic tips into its ends. The position of the tips depends on your CPU socket type.

Then you can either screw the frame to the CPU socket without fastening it tight:

Or you can use a fixing ring to secure the frame on the waterblock (you’ll see the photo in the descriptions of the other liquid cooling systems below).

After that you attach the radiator with fan to your computer case’s back or top panel.

With the mainboard installed, you mount the waterblock on your CPU, fastening the screws.

That’s all. You only need to connect the pump and fan to your mainboard’s connectors and start your computer up. The whole procedure of installing the Corsair Hydro H55 Quiet or similar coolers takes no more than 15 minutes.
