Cryorig C1 – Test and Review

It was not long ago when I performed a test and review on a previous Cryorig cooler – the H5 Ultimate. I’m now more than happy to see that I’ve got another sample to check and add to the ever increasing list of reviews at DVtests and this sample is called Cryorig C1. A cooler that is elegant and compact, made to be installed in smaller form factor PCs and still perform at a great level, while staying quiet and beautifully looking. Cryorig C1 could very well be your next consideration for that small gaming rig you’ve cramped in the living room.

You can also have a closer look at one of our previous reviews of Cryorig products:








Hope you’ve enjoyed the previous reviews, so let’s get on with the new one and check out what this little fellow can do.

Cryorig C1 looks quite good even before taking a look inside the box and my first thoughts were whether it was damaged due to a drop that had possibly happened with the courier. One of the box sides was relatively damaged, but more on that later.

The tech font, along with standard blue/black/white color scheme make this product box a thing of beauty and a good reminder that we’re in 21st century, so we’re really into interesting boxes, unboxing experience and overall product presentation.

Looking around the product box makes me informed about the technical specifications, technological features and all information required to make the decision whether this cooler is a good option for a given customer. Opening the first lid presents a view of the Cryorig C1 cooler in all its glory. Moving forward with the box opening I was presented with a large compartment made of carton that houses all additional accessories and manuals.

A thing of note to say here is the additional carton that is installed in the box sides to help with overall box strength and rigidity. Fortunately enough there was no real visible damage on the inside and I can safely say the harm on the outside wasn’t enough to punch through the internal defense. Great.

Inside the large compartment there were all the included additional accessories, all of them wrapped neatly in transparent nylon bags. Several smaller areas were outlined with carton that were labeled on the compartment cover – very nice touch indeed.

Let’s check out the included accessories and what they offer.



After removing all the nylons with the help of a pair of scissors, I arranged them for a photo on my soft desk surface (large scale mouse pad) and here they are.  familiar package of additional accessories I have to say, not much different from other Cryorig coolers. Of course, there was something different, which was an alcohol pad to support you in removing the old thermal grease on your CPU cover-  nice touch and I hope Cryorig will include such pads in their future CPU product shipments.

The standard Cryorig C1 package offers:

  • 1 x Cryorig screwdriver
  • 1 x Product registration card for extending the warranty with additional 3 years
  • 1 x Installation manual (Intel and AMD)
  • 1 x back plate for Intel
  • 1 x back plate for AMD
  • 1 x syringe of premium Cryorig CP9 thermal compound
  • 1 x rubber piece for s.775
  • 4 x  long metal fan screws painted in black
  • 4 x short metal screws painted in black
  • 4 x  metal pillars
  • 4 x metal nuts
  • 2 x metal bars
  • 4 x rubber mounts for non-slim fan
  • 1 x alcohol pad
  • 1 x XT140mm cooling fan

Extensive additional accessories package that will ensure your hassle free installation experience along with upgrade options, should you need them. Happily, typical Cryorig quality was present on all the included parts, especially the metal ones. The way things are supposed to be.

Now that I’ve checked the additional accessories, let’s move forward with the cooler’s examination – its structure and design.



Cryorig C1 isn’t your typically designed CPU cooler. It’s much more than that and due to its size restrictions there are many challenges in building an efficient cooler, capable of handling demanding environment. Luckily Cryorig C1 appears to have been quite properly designed with the help and support of proprietary Cryorig technologies making the finished product excellent in many ways.

Having said that, one of the technologies used here is called DirectCompress™, enabling all soldered heat pipes using this technique to have around 10% more contact surface than other traditional methods of soldering. In general more contact surface would mean better heat distribution, leading to cooler CPU temperatures.

C1 contact plate C1 design


C1’s physical dimensions are L144.5 mm x W140 mm x H74 mm (with fan) and the total weight comes in at 628 g. Without the fan scales are showing 539 g. of weight.

Perfectly milled C1100 Pure copper nickel plated contact plate with dimensions of 40 x 40 mm is visible on the top left photo. Excellent execution as previous tested products and this contact plate would ensure perfect CPU contact. Six units of Ø6mm nickel coated copper heat pipes, 4 of which are shaped in U-style design, making Cryorig C1 so compact and effectively suitable for ITX motherboards, along with any other motherboard where the computer case could be smaller in size. Such design is extremely user friendly and would allow for C1 to be installed in really cramped cases.

Additionally, 4 of the heat pipes (U-shaped) allow for two way heat spreading thus increasing their carrying capacity.

As in previous models of Cryorig’s CPU coolers, here we have a top frame around the heat sink. It’s painted in white and made of plastic with an aesthetic function as well as a fan bed (fan is mounted on top).

Now that I’ve covered the heat sink design, let’s move on with the fin stack and how it was executed in this versatile cooler.

C1 side view C1 frontal view


Cryorig C1 has an asymmetrical design on the fin stack due to two facts – additional tighter fin stack underneath the top one and the top one that has an offset to the right, covering DIMM slots on the motherboard. Jet Fin Acceleration System™ is present here, especially due to the smaller fin stack that has different fin gap in order to accelerate the airflow, moving hot air faster.

Top fin stack has 56 pieces of 0.4mm thick fins with 1.8mm of gap between each other, while the smaller radiator consists of 35 pieces, again 0.4mm thich, but with tighter gap of 1.4mm. This allows for more efficient cooling and better airflow distribution, allowing the compact Cryorig C1 to effectively cool down around 140W of TDP.

Of course, what’s a CPU cooler without its best friend – the fan. Let’s take a closer look at the included one here.

XT140 fan and installation screws XT140 – slim 140mm fan


Out of the box Cryorig C1 comes with one 140mm fan with model name – XT140. Its physical dimensions are L140 mm x W140 mm x H13 mm and weight of 89 g. Xt140 is designed with grey square frame, completed with rubber mounts (Acoustic Vibration Absorbers) on the corners to dampen any vibrations and a propeller with 13 narrow blades. Piano black finish along with matte black design on the plastic make this fan good looking and visually pleasing. XT140 has a speed range of 700 – 1300 RPM and noise level of 20 to 24 dBA respectively. In terms of airflow level – 65 CFM is the maximum possible output while maintaining air pressure of 1.49 mmH2O. Not bad for a slim fan. PWM 4-pin fan connector with a black sleeved cable is present on the fan.

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

Patented MultiSeg™ quick mounting system makes the installation of this cooler an easy task. Below are all supported sockets currently.

  1. Intel sockets: LGA1156, LGA1155, LGA1151, LGA1150, LGA775, LGA 1366, LGA2011, LGA2011 v3
  2. AMD sockets:  AM2, AM2+, AM3, AM3+, FM1, FM2, FM2+, (upgradeable to AM4)

Before moving any further with the actual installation of the cooler I will need to consult myself with the included installation manual and be completely prepared. Although I’m now familiar with Cryorig’s mounting system it’s always advisable to seek support in the included manuals before undergoing any installation, as this will ensure your hassle free experience along with no material damage.

C1 Intel mounting kit C1 ready for installation


First step into installing Cryorig C1 on the motherboard socket is to ensure you’ve properly aligned the metal back plate, which has plastic sliders corresponding to each Intel socket. After referring to the manual you will know which ones should fit your motherboard socket. For convenience Cryorig included letters on the back plate that correspond to different sockets. After aligning the back plate and making sure it’s evenly fitted through all socket holes you need to bolt on the metal pillars, all four of them. Next step is to cover the metal pillars with the two metal bars that will be holding the cooler into place. Hand tighten all parts until the screws stop, there is no need to go further than that. This is one of the perks of MultiSeg™  quick mounting system.

Second to last step is to place the heat sink on top of the metal bars after you’ve squeezed some thermal paste on the CPU cover. Firmly grab the heat sink and using the specially designed holes in the fin stack screw the cooler into place. Again – no need to go further after the screws stop turning.

Here is what Cryorig C1 looks like when installed.

You can now safely install the fan using the 4 long metal screws that keep the fan into place.

Here is a photo of the cooler, already installed and ready to take some action. Its looks are quite eye pleasing in fact. All set – quick and easy.

Looking at this photo it’s clearly visible that the cooler appears small on this motherboard (ATX). Due to that there is no DIMM slot interference, nor is there RAM compatibility issues. Depending on the way you install the cooler (heat pipes facing the RAM or facing the motherboard ports) you will achieve different compatibility.

Since the cooler is installed and ready to face the tests I believe it is time to check my testing rig and continue onward with the review.



Intel Z97 Test system

  • CPU: Intel i5-4670K
  1. At standard frequency 3.400 MHz (Voltage set to Auto when not OC-ing)
  2. At low overclock frequency of 3.900 MHz  (at 1.205V)
  • Motherboard: ASUS Maximus VII HERO Z97
  • Video card: MSI AMD R9 280X GAMING 3G
  • Memory: Kingston Hyper-X SAVAGE 8 GB, Dual channel, 1866 MHz
  • Solid State Drive: Intel 530 Series, 120 GB
  • Hard drive: Western Digital 1 TB RED NAS series
  • Case: Aerocool Aero 1000
  • Power supply:  Corsair RM750 W
  • Cooler: Cryorig C1
  • Thermal paste: Noctua NT-H1

For this test and review I am going to use the standard XT140 balance fan working at full speed of 1300 revolutions per minute providing airflow level of 65 CFM at noise level of 24 dB(A).

The tests were conducted in a closed system with:

  1. 2 x Aerocool 120mm case fans – mounte on the front panel and sucking fresh air in, spinning at about 1200 RPM
  2. 1 x Aerocool 120mm case fan – rear mounted, serving as exhaust and spinning at about 1200 RPM
  3. Room temperature of about 22 degrees.

The Aerocool 120mm fans were connected to the motherboard fan headers and were rotating at maximum speed.

And here I want to describe my testing method.

I will install Cryorig C1 and do stress tests using Prime95 AVX software with constant load on the cooler for 14:30 minutes with custom settings of minimum FFT size (in K of 128), max FFT size (in K of 128) and Run FFTs in place at standard frequency of 3.400 MHz (at Auto Voltage) and at low overclock frequency of 3.900 MHz(at 1.205V) using only the fan provided in the package, installed on the front of the fin stack.

Now let’s check out the test results that Cryorig C1 was able to deliver at Idle:

And when overclocked:

Cryorig C1 @3.9 GHz, Load Cryorig C1 @3.9 GHz, Load


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

And the fan speed during the tests:

I think the time to express my initial thoughts and feelings about this product has arrived.



1. Cryorig C1 performance:

From the first moment I’ve laid my hands on the C1 cooler I’ve been very interested in it. It’s quite well built and offers great compatibility. Product presentation is on an excellent level with all included accessories that are of fine quality. It’s AM4 compatible as well (with a separate purchase) and supports all modern sockets of the Intel family along with AMD’s processors.

C1 from Cryorig is a surprisingly well performing, compact cooler made to be installed even at high performing ITX machines. PWM control is great, provides smooth transition of RPMs and adds to the value of the cooler. Noise levels are acceptable even at maximum RPMs, although it really depends how much it your tolerance level for noise. I’m sensitive about PC noise and it was quite acceptable for me when working below 1000 RPM.

Performance wise it did a decent job keeping the CPU cool at idle frequency all things considered. The test at 4.3 GHz was missed due to my belief that it would have been unnecessary load on the CPU, after all over 70 degrees isn’t the healthiest thing you can do to your CPU. I’m sure that other systems will see many benefits of having Cryorig C1 installed and even slightly overclocked.

Great compatibility, lots of technological features and overall solid performance.

2. Cryorig C1 appearance:

Beautiful design that is completed fully by the lovely white plastic frame around the top fin stack. Typical color scheme for the included fan – all Cryorig style and futuristic overall design. Surely a distinctive cooler among the bunch, especially of the C and U shaped ones. Black sleeved cable is a nice touch and a must these days. To put it simply I have no complaints against this cooler – it’s an excellent choice in its product niche.

According to my review, I think that Cryorig C1 deserves the following award:


Official price (MSRP) for Cryorig C1: 64.99 USD

Official warranty: up to 6 years with the extender warranty card

Special thanks to Cryorig for providing us with a test sample!
