CRYORIG C1 CPU Cooler Review

March 4th, 2015 James Leave a comment Go to comments


Some time ago pcG Mike looked at a new CPU Cooler from a new company, the cooler was an R1 Ultimate and the company was CRYORIG. pcG Mike was so impressed the CRYORIG R1 Ultimate walked away with a pcGameware Gold award. Well now it’s my turn as today I’ll be taking a look at the CRYORIG C1, and it’s a far different beast to the R1. So what is it then?

Well most importantly the CRYORIG C1 is a top down cooler specifically designed for Small Form Factor (SFF) cases (MATX, MITX) mainly down to its very low profile. The C1 is just 74mm high with its slim (13mm) 140mm fan fitted. The overall dimensions of the cooler are (L144.5 mm x W140 mm x H74 mm), and due to the heatsink’s offset nature it means that the cooler totally covers the RAM slots on your motherboard. This obviously means that clearance is key! The cooler weighs in at 628g with fan and 539g without. There’s a total of six U-Type 6mm heatpipes helping to spread that heat load in two directions at the same time in an aide to cooling.

Heat Transfer

Featuring our patented DirectCompress™ Soldering, each heatpipe has 10% more contact surface than traditional manufacturing methods. Increased contact surface means more heat transferred and a cooler CPU.

Moving More Heat
Double Heatpipe

U-Type heatpipes spreads heat in two Directions simultaneously increasing heat carrying capacity. The C1 has a total of 6 full copper sintered heatpipes, containing 4 high capacity U-Type heatpipes nearly doubling the cooling capacity.

The CRYORIG C1 arrived at pcG in a very large box, with an oversized image of the C1 on the front. On the front we can also see the CRYORIG name and logo, with the following being highlighted – ‘The C1 Top-Down Cooler is engineered cool, compact and compatible. Featuring CRYORIG patented design, with one XT140 high performance low noise fan’. The back of the box lists the heatsink specifications and the XT140 fan specifications, along with showing us four technical drawings of the CPU Cooler itself, providing specific dimension information. In addition to this there’s a full set of images depicting motherboard/socket compatibility.

The left side of the box leaves us in no doubt what CRYORIG cooler we have, and the right side of the box goes on to highlight the following:


Low Profile Power Designed for ITX Systems
The C1 is made for ITX/MicroATX systems. Low profile and highly adaptive, the C1 will fit in places where other coolers cannot while providing CRYORIG performance quality.

U-Type Heatpipes Maximum TDP Performance
With 4 ‘Double TDP Capacity U-Type Heatpipes’ and a total of 6 pure copper heatpipes, the C1 brings extreme efficiency in a small package.
5 Step Easy Installation Get Started in 5 Minutes
Featuring the MultiSeg Quick Mount System, installation is fast easy and reliable.

Unboxing the CRYORIG C1 is a real treat and is not dissimilar to unboxing a Noctua product! Everything from lifting the lid of the box and seeing that lovely image of the top of the cooler, to the fact that each part has its own box, with its contents clearly marked on the box itself. Even the layout of the accessories depicted on the top of the box actually matches the same layout within the box! It really is impressive stuff, and makes you feel that you’ve got a premium product at hand.

Within the outer box we find two inner cardboard boxes, with everything beautifully packaged and presented. In the larger of the two boxes we find the heatsink and the XT140 fan. In the other box we find all of the associated accessories, amongst the accessories we find CRYORIG’s own thermal paste (CP9), an alcohol pad to clean the CPU and there’s even a CRYORIG branded screwdriver! 😉

At the time of review the CRYORIG C1 is retailing for approximatley £45 at Ebuyer and comes with a two year warranty.

First Impressions


After the impressive unboxing I was expecting great things from the CPU Cooler within and I wasn’t disappointed! The CRYORIG C1 is not only a good looking, well made cooler, but it’s also like no other cooler I have seen before. This is obviously due to the fact that it’s a top down cooler, and it’s massive! This should make for an interesting review…


CryoRig C1


Looking at the cooler from the top (heatpipes facing us) you can begin to appreciate how low and wide the CRYORIG C1 is, you can also see the white shroud that helps to channel air down across the stacked heatsinks. You also get to see those six U-Type heatpipes that are made from all copper and nickel plated. Looking from the opposite side we can see how large the offset is and we can also see that all of your RAM slots will be covered (and be made inaccessible) once the C1 is in place. The top of the cooler is obviously dominated by the 140mm XT140 fan, with its 1300RPM max speed, 65CFM of air flow and its associated 24 dBA of noise.

Looking from the sides of the CRYORIG C1 we can really appreciate that offset as well as see that lower heatsink in the centre. The upper heatsink features 2.4mm gaps between the fins while the lower one has 1.8mm gaps, this helps to speed up the airflow through the cooler.

Looking at the bottom of the CRYORIG C1 we can clearly see the two separate heatsinks, the mounting mechanism (just two spring loaded screws) and the central baseplate with its sticker (WARNING Please peel this label off before you use!), oh and made in China BTW! 😉

At this point I’m really impressed with this new CPU Cooler from CRYORIG, it’s great where CPU Cooler height is an issue, with its maximum height of 74mm, even RAM clearance is good at 42mm. Add to this a great design, backed up by high quality engineering and materials and it looks like CRYORIG could have another winner on their hands.


Hardware Installation


  • Test Rig Setup

  • Case Cooler Master HAF XB Power Supply Corsair Professional Series AX 760i
    Motherboard ASRock Fatal1ty Z97X Killer CPU Intel Core i5-4690K
    CPU Cooler CRYORIG C1 RAM HyperX Savage 2400MHz 8GB Kit
    Graphics Card XFX AMD Radeon R9 290X DD Black Edition SSD HyperX FURY 120GB


    The first task for installing the CRYORIG C1 was to ascertain what components I would require for our socket 1150 installation. The box information provided and the instructions were clear, as I would be using the INTEL MutiSeg QUICK MOUNT SYSTEM supplied. This comprises of the MultiSeg Backplate and the two Intel mounting bars, the LGA 775 Backplate Foam would not be needed. To assemble the bracket and bars, we would also need x4 Thumb Screw Caps and x4 Screw Pillars, all of these components are shown below left.

    Installation onto our test motherboard (ASRock Fatal1ty Z97X Killer) was a simple case of threading the uprights on the backplate through from the back of the board, and secure in place by way of the four Screw Pillars. IMPORTANT: At this point you’ll want to make sure your CPU of choice is in place. As once the two Mounting Bars are secured in position, using the four Thumb Screw Caps, you wont be able to get the CPU out! AND: Don’t forget to fit your RAM, as once the cooler’s in place there’s no hope! Also note that the bars fit at the top and bottom of the CPU socket, not the left and the right which tends to be the norm…

    Finally the CPU backplate sticker can be removed (we wouldn’t want to forget to do that would we Mike!?) revealing that nice smooth ground surface. A small pea sized blob of (Arctic Cooling MX-4 was added and the cooler can now be screwed into position. Be careful to tighten one or two turns per side as you go, do not tighten one side before the other…

    As you can see from the images above our test RAM (HyperX Savage) has plenty of clearance between the heatsink and the modules. You can also see from the images how clever CRYORIG have been by incorporating a large chunk of the heatsink surface directly above the CPU itself, utilising basically all of the free space available. The 140mm fan was simply plugged into CPU Fan Header 1 on the ASRock board courtesy of the attached braided cable.

    Once installed you can see that the CRYORIG C1 dominates the motherboard area, but it still looks good, but you’re not going to see your RAM modules any time soon! I must admit to rather liking this new look, the C1 may be designed for Small Form Factor motherboards and cases, but looking at it now I would even consider it for a normal ATX build too, assuming that its cooling performance is up to scratch…


    Testing Methodology/Setup


    CRYORIG C1 - Thermostat For CPU Cooler testing, we here at pcGameware run Prime95 for a 15 minute period. During this period the temperature is monitored with CoreTemp and the cooling performance recorded (the max recorded is the average for all cores). Between each stress test we allow a 15 minute cool-down to allow for more accurate results. To adjust the fan speed we simply use the UEFI. A close eye is also kept on the ambient temperature, with the maximum being recorded for each run, this allows us to calculate the Delta temperature (Core – Ambient = Delta). Each run was performed with the Intel Core i5-4690K CPU at the following frequencies: 3.5GHz (Stock) and 4.0GHz (using the ASROCK OC Tweaker, shown in the picture below), all results have been recorded with CPU-Z.

    * Please note: To ascertain the maximum and minimum noise levels produced by our CPU test coolers. The dB is recorded at a distance of 1 metre from the cooler, with all case fans unplugged to isolate the sound in question.


    UEFI OC Disabled (3.5GHz) UEFI Overclock (4.0GHz)


    Processor speed is set using the OC Tweaker tab of the UEFI, “Disabled” for stock speeds (3.5GHz) and “Turbo 4.0GHz” for the minor overclock tests. It should be noted that changing the OC settings resets the Fan Speeds, so these are checked on the next reboot and reset to “Full Speed” (see below).


    UEFI Fan Options UEFI  Fan Settings UEFI Fan Speeds


    All the fans installed in the system are set to 100% speed using the displayed settings, this is simple with the ASROCK UEFI with the option of “Full Speed” being available for all system fans (bar the Power Supply Fan header).

    Hardware Performance


    As stated above, to make our performance tests easier to follow and to get the most accurate recordings, all of the following tests have been carried out with case fans set at 100% and the CRYORIG C1 fan also set at 100%.

    * Thermals Explained


    We can clearly see from the data above that the CRYORIG C1 can’t compete with the regular tower CPU Coolers, this is most likely down to the fact that the hot air coming off of the back (or bottom in this case) of the cooler is no longer being expelled out of the back of the case, courtesy of a defacto exhaust fan. Instead the hot air is blown back into the case. Having said that the only cooler that’s fair to really compare the CRYORIG C1 to is the SilverStone Argon AR06 as it’s also a top down cooler, and the C1 destroys that when it comes to performance…

    * Thermals Explained


    For the next thermal test, our i5-4690K is given a small overclock and set at 4.0GHz using the ASROCK OC Tweaker within the UEFI. This not only provides us with more CPU power, but also a higher voltage (1.156v) to stabilise it which then leads to more heat. The CRYORIG C1 still (unsurprisingly) finds itself near the bottom of the grid as it shows once again; a top down cooler cannot compete with even the most basic tower cooler.

    But of course to criticise the CRYORIG C1 based upon its performance would be to miss the point of the cooler in the first place. AS the C1 can fit where none of the other coolers can. And what’s also obvious from the data (given a 65.75C max while overclocked) the C1 is more than adequate for daily use even with an overclock! Especially as we have stated before, no one sits down for an evening of Prime 95! Or do they… 😉


  • Acoustics

    I assumed that the slim profile 140mm XT140 fan would be relatively quite thanks to its size and its maximum speed of 1300RPM. But I was a little off the mark as with all of the case fans off and the GPU at idle the CRYORIG c1 was measured (from 1m away) at 42dB. No while that’s not LOUD, it can easily be heard over general silence at around 30dB. But don’t forget that this is at 100% fan speed while running Prime 95! For a HTPC or Living Room PC and even a Gaming Rig, with the fan set on auto (courtesy of PWM control) the noise is likely to be far less…


    Final Thoughts


    The CRYORIG C1 is one of the best presented and best made CPU Coolers I have seen, just remember that this cooler is more about where it can fit than about its cooling performance.

    The CRYORIG C1 came to pcG in a large smart box with the contents beautifully packaged and presented, easily one of the best unboxing experiences I have ever had, hat’s of to CRYORIG for that! Once out of the box the interest in the C1 continued to grow as not only is this a unique looking cooler, but it’s also very well made. Everything from the fittings, to the cooler and its fan, to the supplied accessories (thermal paste, alcohol wipe even a Branded screwdriver!).

    Thanks to CRYORIG’s INTEL MutiSeg QUICK MOUNT SYSTEM installation was very easy, with the mounting hardware taking just a few minutes to assemble and fix to the motherboard. Attaching the CPU Cooler itself was also a simple task of tightening two screws (using the lovely supplied screwdriver of course!). RAM clearance was also good (don’t forget to install first!) at 42mm and we had no clearance issues with our HyperX Savage RAM.

    In testing, and when compared to all other coolers (which is a little unfair) the CRYORIG didn’t perform well with the second highest temp we have seen in both the 3.5GHz and the 4.0GHz tests. Now while this may seem poor it’s not! This is because of the fact that a top down cooler will never likely perform better than a tower, therefore the CRYRIG’s only true competition is the SilverStone Argon AR06 and the C1 cools way better than that does…

    What we must establish here is what the CRYORIG C1’s main goal is, and that’s not one of incredible heat dissipation, it’s the fact that the CRYORIG C1 can go where no other cooler has gone before (sorry couldn’t resist!). 😉

    Acoustically I was a little disappointed also, as the C1 put out 42db with its single 140mm fan at full speed, while it’s not loud in comparison, it’s not silent either.

    Overall though CRYORIG have an excellent cooler on their hands with the C1, it’s beautifully made, easy to install and it can fit in almost any Small Form Factor case, just don’t expect great cooling as well…
