Cryorig H7 CPU Cooler Review

February 17th, 2016 James Leave a comment Go to comments



It’s been some time since we’ve seen something form new CPU Cooler specialist Cryorig, in fact it’s been over a year since we looked at the impressive Cryorig R1. But Cryorig have been busy and today we will be taking a look at their new entry level cooler the Cryorig H7.

The Cryorig H7 is a small compact CPU Cooler made from pure cooper and nickel plated, it measures in at 123mm (W) x 145mm (H) x 98m (D) and weighs in at 711g with fan. The cooler comprises of a single heatsink stack with three 6mm heatpipes and a 120mm fan with a rated maximum speed of 1600RPM. Also due to the heatsink’s offset this CPU Cooler offers limitless RAM compatibility as there is no overhang at all!


cryorig logo ‘CRYORIG H Series coolers feature our proprietary Hive Fin™ structure. This design allows for a combination of Jet Fin Acceleration™ and Turbulence Reduction, as well as strengthening structural strength of the fin stacks. Combined together, the Hive Fin™ design brings cool innovation. By utilizing a larger air intake and narrower air exhaust section on the fins, compresses the air to move faster while exiting the heatsink. Jet Fin Acceleration System™ carries the hot air out of the system faster and more efficiently. Utilizing a bee hive shaped structure at the front air intake of the heatsink, lowers air turbulence and straightens out the airflow. Assisting airflow to move directly through the full length of the heatsink and carrying out hot air. The H7’s Heatpipe Convex-Align™ System allows for more heatpipes in a given area, optimized heatpipe placement in the copper base, and improved alignment with your CPU. With the Heatpipe Convex-Align™ System, each heatpipe functions to their maximum TDP capacity.’

The Cryorig H7 arrived at pcG in a smart predominately black box with a large image of the H7 cooler on the front. The front of the box gives very little else away other than the brand, product name and a brief statement: ‘Designed for efficiency and performance, the H7 features CRYORIG’s propriety Hive Fin and QF120 120mm PWM fan for a highly efficient and compatible package’.

The left side of the box features three additional images highlighting the Extreme Efficiency Fine Tuning Cooling Capacity, Zero Interference Infinite RAM Compatibility and Installation Made Easy Get Started Within 4 Minutes. This last statement looks interesting… 😉

The back of the box features four technical drawings providing detailed dimensional information on both the CPU Cooler itself and its associated fan. In addition to this we also find the cooler specifications and features (see Specifications/Features below). Finally we can see the CPU Socket support list at the bottom, with the H7 supporting Intel Socket LGA 1150, 1155 & 1156 as well as AMD Socket FM1, FM2/+, AM2/+ and AM3/+.

On opening the top of the box we are greeted with a cool blue panel regarding registration and the extended three year warranty. This is always good to see as some manufacturers seem to like to hide their warranty information away behind their website, but not Cryorig! 😉

Delving deeper into the box we eventually come across the top of the H7 cooler itself. As you can see the cooler and its associated accessories were both well packaged and nicely presented.


Cryorig H7 - box contents


Within the box other than the CPU Cooler heatsink itself and the single 120mm fan, we find a Install Manual, an additional set of fan clips, blackplate and screws etc and a syringe of Cryorig’s own CP9 thermal paste.


At the time of writing the Cryorig H7 is retailing on Amazon for approximately £40 and comes with a 3 year warranty.

First Impressions


Cryorig H7


First impressions of the Cryorig H7 are really rather good, in fact they’re great! The H7 is one of the nicest (bad word, soz) looking CPU Coolers that I’ve seen and I very much like its compact design and the offset stack. In fact (as already stated by Cryorig) the stack is offset at such an angle that there are NO issues with Memory/RAM compatibility however tall it might be. And that is always good news… 🙂


Cryorig H7 - front Cryorig H7 - side Cryorig H7 - back


Looking at the Cryorig H7 from the front we can clearly see the distinctive Hive Fin™ design. The design is supposed to help accelerate the air towards the back of the cooler and reduce turbulence.

Looking at the cooler from the side we can clearly see the offset design, keeping the cooler’s stack and fan away from the RAM for maximum compatibility.

Looking at the H7 from the back we see that the Hive Fin™ design is now gone and is now replaced with a more regular design. There are in fact 40 aluminum fins in total, and they are all of a decent thickness and don’t seem top want to bend too easily.


Cryorig H7 - top Cryorig H7 - bottom


As you can see the top of the Cryorig H7 features a smart looking top cover made from black plastic and sporting a simple Cryorig logo. This actually helps to tidy up the cooler’s aesthetics and helps to hide the tops of the heatpipes, that can often look a little ugly. The hole in the top allows access to the single screw that hold the bracket arms to the top of the cooler’s base plate, should you want to remove them (although there’s no reason to do so).

Looking at the bottom of the H7 allows us to appreciate the unusual design of the mounting mechanism, that’s already pre-installed. The arms are actually arranged and move in a scissor fashion allowing for compatibility (both Intel & AMD) without the need for additional parts, clever stuff! The base itself is made from Copper and Nickel plated and of course, it’s always a good idea to remove that protective film first before installing… 😉 Here we can also see the three 6mm heatpipes that reside with the copper base and are not exposed in anyway.


Cryorig H7 - fan front Cryorig H7 - fan back


Although the Cryorig H7 supports two 120mm fans only one is actually supplied. The supplied QF120 fan has a rotational speed of 330 ~ 1600 RPM ±10 % and produces a maximum CFM of 49 whilst making up to 25dBA of noise. The fan itself is nicely designed and seems well made, featuring a short braided cable, rubber mount points and markings showing you both flow direction and fan rotation.


Cryorig H7 - comparison (front) Cryorig H7 - comparison (side)


The Cryorig H7 measures in at 123mm (W) x 145mm (H) x 98m (D). And, looking at the Cryorig H7 in comparison to our stock cooler the Noctua NH-U12S we can see that the Noctua is taller yet narrower than the H7, but the width is approximately the same. You can also clearly see the offset of the H7 in comparison to the NH-U12S, that has no offset. The Cryorig is definitely the better looking of the two though… 😉


It’s strange what some of us like and some of us don’t, but I personally really like the look of this Cryorig H7 cooler, in fact if it was based upon looks alone I’d be giving this H7 a Platinum award! The H7 is simply really well made and looks great, with a design that’s likely to fit in with any Rig build. Unfortunately (maybe?) for Cryorig there’s the small matter of getting it installed, and then the all important part of finding out how good a job it does of cooling our toasty Skylake CPU. Let’s crack on an find out shall we…


Hardware Installation


  • Test Rig Setup

  • Case Cooler Master HAF XB Power Supply Corsair Professional Series AX 760i
    Motherboard ASRock Fatal1ty Z170 GAMING K6 CPU Intel Core i5-6600K
    CPU Cooler Cryorig H7 RAM G Skill Ripjaws 4 16GB
    Graphics Card EVGA GeForce GTX 980Ti Classified SSD HyperX FURY 120GB


    Cryorig H7 - mounting for 115x


    Usually at this point it’s time to sift through all of the supplied parts (maybe read the instructions!) and work out what parts you’ll need. Not so with the Cryorig H7 as you’ll be using all of the parts, and that a good thing, as there’s only nine of them! That’s right folks, thanks to the clever boffins over at Cryorig all you’ll need is the backplate, the four spacers and the four screws, regardless whether you’re installing on Intel or AMD! Very clever…


    Cryorig H7 - installation (mounts) Cryorig H7 - installation (backplate)


    The first task then was to secure the backplate to the motherboard, at first I couldn’t quite work out how the backplate would stay in place as at this point there’s nothing to screw into!? But what Cryorig have done is rather clever (and not something I’ve seen before) in that the the screws themselves feature a small knurled section that causes an interference fit with the black plastic spacers. Thus holding everything in place, and it works too! 😉


    Cryorig H7 - insatlled (heatsink) Cryorig H7 - installed (heatsink & fan)


    Unfortunately the next bit, fitting the heatsink to the mounting system is not quite so clever! 🙁 This is because you have to screw the screws into the heatsink brackets from the back, as the heatsink already has the brackets/arms (that actually move in a scissor fashion) attached. Now assuming this MB assembly may already be in the case, this is not going to be easy… You have to hold the cooler in place on one side while screwing from the other (see video). Now although this can be achieved it also promotes another problem, in that as the heatsink is waving around in your hand as you juggle everything, you’re likely to miss-align the cooler baseplate to the top of the CPU. This is simply down to the fact that it’s hard enough to hold everything, let alone hold it all square! This certainly has the ability to impact cooling performance IMHO.

    But with that tricky part out of the way the fan could be refitted. Very easy thanks to some well designed clips and of course impressive RAM clearance thanks to that heavily offset heatsink stack.

    Hopefully the images above give you some idea of the impressive Memory/RAM clearance that the Cryorig H7 offers. Simply put it’s the best that I’ve seen for a cooler of this type, you simply wont have a problem! 🙂


    Cryorig H7 - installed (above) Cryorig H7 - installed (side)


    Once installed into our test case (Cooler Master HAF XB) we can see again the compact proportions of the H7 and simply how good the overall aesthetic is. It’s certainly a cooler that I’d be more than happy to have in my Case.


    It’s a shame then that there’s a bit of a blip during the install then. Now while it’s far from a nightmare to install it’s a shame that the issue arises due to the clever design in itself (if that makes any sense). Maybe Cryorig have been too clever for their own good!? I simply don’t like the idea of holding the cooler in place while I screw the brackets into position from the other side. I know from a pure engineering point of view this will not help to promote a good CPU to heatsink contact, I guess we will have to see…


    Testing Methodology/Setup


    Cryorig H7 - ambient For CPU Cooler testing, we here at pcGameware run Prime95 for a 15 minute period. During this period the temperature is monitored via ASRock’s F-Stream utility and the CPU temperature recorded. 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 i5-6600K CPU at the following frequencies: 3.9GHz (Stock) and 4.4GHz (using the ASRock OC Tweaker, shown in the images below), all results have also been recorded with CPU-Z.

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


    ASRock UEFI - main ASRock UEFI - Load Optimized CPU OC Setting


    Processor speed is set using the OC Tweaker tab within the UEFI, “Disabled” for stock speeds (3.9GHz) and “Turbo 4.4GHz” for the 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 above right). 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.


    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 H7 fan also set at 100%.


    • Intel Core i5-6600K – 3.9GHz (stock)

    Cryorig H7 Air 100% 24.00 51.00 27.00 41dB


    As you can see from the list above it’s pretty short! That’s because we’ve recently upgraded all of our Test Rigs to the new Skylake platform and this (unfortunately) means that all of the past results are no longer valid for comparison. But we have to upgrade at some point, so please bear with us as over time this list will surely grow and it already is…

    Now I must admit I didn’t expect too much in the way of cooling performance from the Cryorig H7 due to its size, small number of heatpipes and the relative low cost. But I wasn’t quite ready for it to be the least performant CPU Cooler we’ve tested so far on our new Skylake platform. But one really shouldn’t expect too much from this little CPU Cooler either. Let’s see what happens when we lean on it a little more with a heavy overclock and a bit more voltage…

    As I guessed the little Cryorig H7 once again finds itself at the bottom of our results grid, albeit by only 1 degree! But to bemoan this cooler is a little bit foolish as we have to look at what it offers for the money. The first thing that it offers (that’s obviously subjective) is that I think the H7 is one of the best looking coolers I’ve seen and I’m a fan (there’s a joke there somewhere!) of its small dimensions and (to a lesser extent) its clever mounting system. And let’s not overlook that although it might sit at the bottom of our results grid the Cryorig H7 still manages to keep our toasty overclocked Skylake CPU at 65 degrees Celsius when running a Prime 95 Torture Test. And, as I’ve said time and time before there’s not many of us who sit down for an evening of Prime 95, is there!? 😉


  • Acoustics

    Although the noise produced by the 1600RPM 120mm fan was (according to our test equipment) 41dBA, strangely it sounded quieter to me! This I think was down to the fact that the noise had no noticeable tone/whine or hum associated with it, like most other fans seems to have, weird! But I’m sure anyone playing with a headset on wont be to bother by the noise of the fan, even at 100%. Of course due to the fan’s PWM control the noise/performance can be adjusted within your motherboard’s UEFI for the perfect balance.


    Final Thoughts


    OK, so on paper the Cryorig H7 is not the best performing CPU Cooler, but maybe that’s missing the point. What it is; is one of the best looking CPU Coolers I’ve seen that’s got a innovative mounting system and features limitless RAM clearance. It’s also more than capable of cooling an overclocked CPU and the price isn’t too bad either…

    The Cryorig H7 arrived at pcG in a smart predominately black box with its contents both well packaged and presented. It was also nice to open the box and immediately be informed about the products warranty (3 years), something so many other manufacturers shy away from! Once out of the box I soon warmed to this cooler’s compact dimensions (123mm (W) x 145mm (H) x 98m (D) and good looks, as I’ve already said, one of the nicest CPU Coolers I’ve seen!

    Installation was, well interesting at the very least, because the Cryorig H7 has one of the most unique mounting systems that I’ve seen. The pro to this mounting system is that it’s universal, meaning that it’s the same for both Intel and AMD. The other good news is that the mounting system only comprises of just nine parts (backplate, 4 screws & 4 spacers). The con is that the screws themselves need to be tightened from the back (see video) as they screw into the cooler’s brackets directly. This means you need to hold the cooler with one hand while screwing with the other, probably with the motherboard held on its side! The end result will likely be that the cooler’s base will end up at a slight angle to the CPU, the net result of that will be degraded cooling performance. And of course having said all of that, we didn’t get a whole lot of cooling performance out of the H7, and it does concern me that this is simply not helping.

    So the cooling performance wasn’t great with a maximum Core temperature of 65 degrees Celsius in our overclocked Prime 95 Torture Test. But one shouldn’t expect too much from this little, relatively cheap CPU Cooler anyway. What’s it’s more than capable of is keeping an overclocked (4.4GHz @ 1.3v) Skylake CPU cool even when running a Prime 95 Torture Test. Temperatures will be even less while Gaming. It’s also relatively quiet as one would hope really, with a maximum noise output of approximately 41dBA (with fan at 100%) the Cryorig H7 noise output is bearable especially while Gaming with a headset on. Of course due to the fan’s PWM control the noise/performance can be adjusted within your motherboard’s UEFI for the perfect balance.

    It’s strange, as although the Cryorig H7 cooling performance isn’t great I cant help but still love the cooler itself, even after a slightly awkward install. This is simply down to the fact that it offers more than adequate cooling for an overclocked CPU, it’s a nice size (not too big!) and offers 100% Memory/RAM compatibility. And on top of this the Cryorig H7 is simply one of the nicest looking CPU Coolers I’ve seen in a while…

      These are so popular, they’re frequently back-ordered. Took quite a while to get mine…and when I did, it was one of the sloppiest looking computer components I’ve ever seen. I’m guessing they were rushing to get them assembled and mine was lopsided so bad the top plastic piece wouldn’t stay snapped in. Even without this issue, it felt really cheap. Based on this, I recommend getting the H5 Universal. It’s $10 more, but stays in stock because people are more interested in saving a dollar than getting quality. Don’t waste your time on the H7 lottery.
