Cooler Master Hyper 103 – Test and Review

Before I start with the review and later with the tests I think it would be nice to check the whole Cooler Master Hyper Series which already includes various coolers with different dimensions and cooling options:

  1. Hyper Z600 – the first cooler introduced several years ago with dimensions of 127.28 x 127.28 x 160 mm and weight of 1045 g made to work as a passive cooler. The product was really great and unfortunately it is currently end of life;
  2. Hyper 212 series  featuring 212 +, 212 EVO and 212x, coolers made to provide good cooling performance/good noise level balance at decent price supplied with 1 x 120mm fan and suitable to be used with various of processors working at default or a bit overclocked frequencies.
  3. Hyper 412 series featuring 412PWM and 412Slim models, coolers made to provide even better  cooling performance than the 212 models at good noise level supplied with one or two 120mm fans and suitable to be used with various of processors working at default or a bit more overclocked frequencies.
  4. Hyper 612 series offering 612PWM and 612 versions, coolers made to provide the best cooling performance inside the Hyper series at good or low noise level supplied with one 120mm fan and suitable to be used with various of processors working at default or seriously overclocked frequencies.
  5. Hyper TX3 series offering TX3 and TX3 EVO, coolers made to provide entry level performance while working at low to average noise level supplied with one 92mm fan and suitable to be used with entry level processors working at default or just a little bit overclocked frequencies.
  6. Hyper T4 – a cooler with dimensions of 131.6 x 72.5 x 152.3 mm with overall weight of 548g and cooled by a 120mm fan working at 600~1800 RPM (PWM) ± 10% range with airflow level of 24~70 CFM ± 10%.
  7. Hyper 101 – a cooler with dimensions of 83.5 x 68 x 117 mm with overall weight of 315g and cooled by a 80mm fan working at 800 – 3000 R.P.M range with airflow level of 10.9 – 40.8 CFM.

I can say that Hyper series is a really extensive cooler series meant to provide models with various dimensions and cooling capabilities. For this review I am going to check how the latest arrival, Cooler Master Hyper 103, performs and keeps my processor running.

Cooler Master Hyper 103 arrived to me in a pretty standard for the company small and very tight carton box painted in the typical white and purple colours forming the standard colour scheme for the company with a big picture of the cooler itself and some information regarding the main technologies used so this cooler can be created on the front panel. The full technical specifications as usual are on the side of the package, while the back side is used for additional information about the product in several languages. A package which looks pretty nice but after all this article is about the content inside of it.

After I opened the package, the first thing  to notice was the small white box holding all of the additional accessories needed so the cooler can be installed both on Intel and AMD platforms. Beneath the white box was the mounting instructions leaflet with a detailed list of the cooler’s accessories for installing the cooler on both AMD and Intel sockets. And right after that I saw for the first time the cooler carefully packed in a Styrofoam bed protecting the cooler itself.

And these are all things which I found inside the outer shell arranged for picture…


First things first, so let’s get started with checking what’s inside the small white box. 


The standard Cooler Master Hyper 103 package contains:

  1. Two metal brackets for mounting the cooler on Intel LGA 2011/1366/1156/1155/1150/ 775 sockets
  2. Two metal brackets for mounting the cooler on AMD FM2/FM1/AM3+/AM3/AM2 sockets
  3. A combined metal backplate for both Intel and AMD platforms
  4. A lot of screws and nuts for installing the AIO on both Intel and AMD sockets
  5. The standard thermal compound provided with all of the CPU coolers from Cooler Master.
  6. Four plastic caps made to hold the 4 bolts attached to the backplate
  7. Installation and warranty guides

After I checked the additional accessories, I believe it is time to pay some attention to the cooler itself. Cooler Master Hyper 103 offers a pretty tight and at the same time very interesting one-tower cooler structure, featuring a heatsink, a cooling fan and a mounting kit with some important innovations, which I will describe one by one by starting with the heatsink and all of its parts.


Cooler Master Hyper 103 is a cooler featuring a heat-sink with dimensions of 108 x 89.5 x 138.5 mm and overall weight of 580g including the fan, which makes it a very small, compatible and very affordable mainstream product. The cooler itself is made of copper and aluminum parts forming a pretty standard structure featuring: an aluminum contact plate, 3 x Ø6mm U-shaped heat-pipes with direct contact to the processor and aluminum fins.

So let’s get started with the contact plate.

The assymetrical heatpipes
Seen from the bottom
IMG_9176 IMG_9178

Hyper 103 ′s contact surface features an aluminum plate with dimensions of 76.4 x 36 mm shaped as radiator on the top side made to hold the 3 x Ø6mm, U-shaped, pure copper heat-pipes with direct contact to the processor. All of the pipes are soldiered together to the aluminum plate ensuring very tight and rigid structure and the best thermal conducting from the processor to the fins. And here is something which I want to point out. All 3 heatpipes are slightly bent to the back of the cooler, ensuring that when the cooler together with the fan is installed it won’t block any of the memory slots.

And by mentioning the aluminum fin stack, let’s pay some attention to it, too.

Cooler Master Hyper 103 offers a pretty interesting aluminum fin stack structure featuring 40 performance aluminum fins and one visual fin on top of the stack with the logo of the company engraved with very small fin gap made for dispersing the heat coming from the heatpipes.


And here I want to point out that this product features the X-Vent and Air-Guide technologies made for optimizing the air flow toward heatpipes and ultimately reduce CPU temperature.

Hyper 103_webpage_01To be honest, all this information sounds pretty nice and I became really eager to check how this cooler will operate with my new AMD A8-5600k processor.

And by mentioning the fan, let’s check what Cooler Master Hyper 103 uses to keep the aluminum stack cool.

Cooling fan:

Cooler Master Hyper 103 is supplied with one long life sleeved 92 x 25 mm fan, which really reminds me of Blade Master 92mm but with newer and better appearance, working at 800~2,200 RPM (PWM) ± 10% revolutions per minute, providing airflow level range of 15.7~43.1 CFM ± 10%, with static pressure level range of 0.35~2.63 mm H2O ± 10%, at noise level range of 17~30 dBA . And by saying appearance I should point out that the fan is supplied with really good looking blue/UV LEDs providing a nice and stable backlight.


The fan is PWM powered and regulated using a non-sleeved not very long cable and connector.

The fan should be attached to the heatsink via 2 plastic brackets, which came pre-installed. Of course, the plastic brackets feature rubber dumpers for reducing the vibrations of the fan if there are any. Unfortunately, the shape of the aluminum fins stack of the model doesn’t allow a second fan to be installed and boost the overall performance of the product.

And this is what the cooler looks like with the fan installed…

Mounting kit:

The third major part, which I actually believe is the most important one, are the mounting brackets for installing the cooler and according to the official technical details and my pictures above, Cooler Master Hyper 103 is supplied with mounting kits suitable to be used with:

  1. Intel LGA 2011/1366/1156/1155/1150/ 775 sockets
  2. AMD FM2/FM1/AM3+/AM3/AM2 sockets

All of the Intel and AMD sockets require the same backplate and the only difference are the front plates, the screws and bolts needed for connecting the brackets.

Of course, for doing the tests I will use the AMD brackets and these are the parts needed so the cooler can be installed on the motherboard:


First thing to do as always is to open the installation manual, read the instructions carefully and pick up the right accessories for the actual socket…

And after that to prepare the backplate before attaching it to the motherboard.

Second thing is to install the long bolts which will pass through the motherboard and secure them with the plastic caps provided with the cooler. This way they won’t start falling off when installing the cooler itself. With the backplate prepared it was time to install the front brackets to the contact plate and prepare the heatsink to be installed on the motherboard.

And this is what the heatsink looks like with the brackets attached to the contact plate.


I believe with this the cooler is ready to be installed on the motherboard.

With the cooler finally installed we can see that there won’t be any RAM slots blocking and it can work with all kinds of memory including modules with taller heat spreaders.

Before I start testing I think it would be nice to check what system I will use for doing the tests:

Test rig:

CPU: AMD APU A8-5600k

  1. At standard frequency of 3.600 MHz (at 1.320V)
  2. At low overclock frequency of 3.900 MHz  at 1.424V)
  3. At medium overclock frequency of 4.200 MHz (at 1.440V)
  4. At high overclock frequency of 4.500 GHz (at 1.456V)

Motherboard: ECS A85F2-A GOLDEN (V1.0)

Video card: 2 x Gigabyte GV-R927XOC-2GD

Memory: 2 x 4GB Geil Black Dragon 1866 MHz

Hard drive: Kingston SSD SV100S264G

Case: SilverStone Raven RV-03

Power supply: Antec HCP-750W

Cooler: Cooler Master Hyper 103

Thermal paste: Gelid GC-Supreme

Fan mounted:

For this test and review I am going to use the standard fan provided with the cooler working at 800~2,200 RPM (PWM) ± 10% revolutions per minute, providing airflow level range of 15.7~43.1 CFM ± 10%, with static pressure level range of 0.35~2.63 mm H2O ± 10%, at noise level range of 17~30 dBA.

The tests were conducted in a closed system with:

  1. 2 x SilverStone AP181 – 180mm fans on the bottom panel putting fresh air in and spinning at about 1200 rpm
  2. 120mm fan on the top panel taking hot air out and spinning at about 1000 rpm.
  3. Room temperature of about 18 degrees.

Both of the SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed.

Testing procedure:

I will install Cooler Master Hyper 103 and do stress tests at standard frequency of 3.600 GHz (at 1.320V), at low overclock frequency of 3.900 GHz (at 1.424V),  at medium overclock frequency of 4.200 GHz (at 1.440V), and at high overclock frequency of 4.500 GHz (at 1.456V) using just the standard fan provided with the cooler working at maximum speed.

And this is what the CPU cooler looks like when installed inside the case and ready for testing…

And this is how the cooler operates when some load on the processor is applied:

Now let’s check out the test results:

CM Hyper 103 @4200MHz 1.440V CM Hyper 103 @4500MHz 1.456V

All of the test results have been summed up in the following charts:

Results T

And the fan speed during the tests:

Results S

I believe the time for conclusions has arrived…

1. Cooler Master Hyper 103 performance:

After I spent some time unpacking the cooler and all of the additional accessories needed for normal operation, arranging them for taking pictures, installing and finally after I’ve finished testing I can say that Cooler Master Hyper 103  is one really interesting entry level product offering an astonishing performance/noise level balance for its size.

The cooler itself offers a very interesting cube type design, cooled by a very well balanced in view of performance/noise level 92mm model, which can make it the perfect solution for every motherboard providing the option to work with all memories installed, no matter how tall the RAM heat spreaders are and after I am done testing with my pretty hot AMD A8-5600k I can recommend the cooler to be used in every modern rig cooling a low or middle range processors at default or a bit overclocked frequencies without any problem. Unfortunately, for the more powerful processors a better cooler will be required. After all this model offers just 3 heatpipes and not very big cooling surface.

Apart from that, while I was testing the cooler the fan was rotating at about 2500 revolutions per minute and was a bit noisy, but after all of the tests were conducted and the fan was set to operate at PWM controlled mode, it was completely silent and barely reached 1500 revolutions per minute at daily usage.Very nice and very reliable product to be honest.

2. Cooler Master Hyper 103 appearance:

At first sight, Cooler Master Hyper 103 looks like a pretty small and simple product made to provide huge clearance around the CPU socket and the DIMM slots, combined with very attractive and in the same time neutral colour scheme, which can definitely fit in every modern case or can be a base for a modding project. The fan itself offers a dark blue backlight, which boost the overall appearance of the rig.

According to my review, I think that Cooler Master Hyper 103 deserves the following reward:


Official price (MSRP) for  Cooler Master Hyper 103: unknown

Official warranty: 24 months

I thank Cooler Master for the test sample.

    Hi, I was wondering if anyone could answer a few questions I have about this cooler. I have an MSI 970a SLI Krait Edition Motherboard which is similar to the 970 Gaming Motherboard. Due the case I have (Corsair 100r) I can only have Coolers upto a maximum of 150mm Tall. Would this cooler be able to fit inside the case? I also use HyperX Fury RAM and I was wondering if the Cooler would cause any interference with the RAM – I have all 4 DIMMs populated so I cannot move them if the Cooler hangs across the DIMM Slots.

      Hello Charlie,

      Thank you for this comment. It features some interesting questions!

      Let me see if I can answer to them since I never had the chance to touch this motherboard and it will be a matter of a bit guessing and checking pictures.

      1. Would this cooler be able to fit inside the case? — According to the official details of the case and the cpu cooler – yes this product should fit inside this case. Have you ever thought of Noctua NH-L12, which is also a good choice. Low profile but at the same time pretty good performer:

      2. HyperX Fury is with heatspreaders, which are not tall at all. So I believe they will not hit the fan of the cooler. If by any chance they are in contact with the fan, it could be changed easily.

      Best Regards

    This little cutie reminds me my bigger CM Hyper 212 Evo, and of course – Direct Contact rullz 😉 Even small, it really offers such great value/performance/noise ratio, which makes it one of the recommended options for a budget-PC.

      All i can do here is fully agree with you. This small cutie is very well balanced product

        There arent any instructions on how to properly tighten the cooler to the motherboard. I installed mine and tightened until the screws were fingertight. Afraid to go any more… does anyone know if there is a certain number of turns?

        • Dk_vr 31.07.2015 at 8:07

          You are right but the be honest very few coolers are made to fasten the bolts to the end and to offer perfect connection and perfect pressure between the cooler and the processor.
          With CM products I always fasten the bolts by hand up to the moment I can’t rotate them anymore and then with a screwdriver I add a half revolution more.
