Cryorig R1 Ultimate CPU Air Cooler Review

Cryorig is a name that is quite likely new to our fellow enthusiasts. When the company contacted us and asked us to review its news R1 Ultimate cooler, we took a look at the build design and it got us curious. The R1 Ultimate has an overall design that we have seen many times before, but surely had enough "new" to warrant a review.


Today we have the distinct pleasure of introducing a newcomer to the field of CPU cooling. Cryorig is not only a name many of you are probably unfamiliar with, it’s also a name that didn’t exist until last year. Most companies start off low and produce some OEM coolers for a few years to build up relationships and reputation. Cryorig, it seems has jumped in (or gone off) the deep end as it decided to premiere with a high end cooler. As a new company, Cryorig has its work cut out for it in a field of tough competition.

So with an uphill battle ahead, Cryorig is ready to take on the competition with its inaugural heat sink dubbed the R1 Ultimate. Cryorig has given the R1 Ultimate every possible tweak and adjustment one could think of to ensure it has the best performing heatsink available. These tweaks include "DirectCompress," the "Convex-Align" system, and the "Jet Fin Acceleration" system. Fancy names for some clever ideas which I’ll go over in the next section. But it all boils down to one question. Can the R1 deliver?

System Setup

Today's review takes place on our fourth generation [H]ard platform. The test bed consists of the ASUS Z87-Deluxe motherboard, eight gigabytes of Corsair 1600 MHz DDR3 RAM and the Intel Core i7 4770K.

Test Methods


The biggest change you will notice is the removal of hardware testing. In recent years, Intel has shifted their methods of testing to software based and so we find it acceptable to do the same.


Once again we have an integrated GPU in our processor which alleviates the need for a discrete one. With the removal of a discrete GPU comes the advantage of not having an additional variable to account for.

The iGPU will not create any anomalies in our testing as long as we practice consistent testing methods.


Corsair was kind enough to provide us with their Carbide series chassis. It provides excellent airflow and interior space and is a good reflection on current case design.

Thermal Paste

Noctua's NT-H1 thermal paste was selected as the paste of choice for a few key reasons. The thermal paste has been shown to provide excellent thermal conductivity allowing the heat sinks to better do their job. There is no observed curing time. That is, performance does not get any better over time. Any curing time could have introduced variables into the equation causing at best dubious results and at worst unreliable ones.


Ambient temperature will be kept at 25C for the duration of the tests and measured with a MicroTemp EXP non-contact infrared thermometer and cross referenced with the Sperry Digital 4 Point thermometer. Any variance greater then 0.2C will halt the testing until temperatures return within spec for fifteen minutes.


Idle temperatures will be recorded after a twenty minute period of inactivity. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes.


Load temperatures will be recorded after a twenty minute period of 100% load. To obtain this load we will be using AIDA64 Extreme Edition v3.00.2500. This places an even greater load on the CPU than before and includes some benefits. Because the load is so extreme we see the temperature vary wildly from 72C to 86C in some instances. To get an accurate reading we will utilize AIDA64’s ability to average the temperature over time. Given twenty minutes at 100% load we arrive at a temperature that accurately represents our heatsink’s performance.


Sound levels will be measured with a Reliability Direct AR824 sound meter from a distance of four feet away. With everything turned off and the room completely silent the meter registered a sound level of 38dB(A). This is a very quiet room where a simple pin drop could be heard. All sound measurements are recorded in the very late evening to further reduce any ambient noise.
