Cryorig R1 Ultimate CPU Cooler Review
Cryorig R1 Ultimate CPU Cooler – Prime 95 Temperature Testing Results
Idle results recorded using RealTemp after sitting idle at desktop for 15 minutes. Load temperatures were recorded after running 30 minutes of Prime 95. All testing was done outside of the case with an ambient room temperature for 72 degrees. We used Antec Formula 7 Nano Diamond thermal compound for all testing to ensure results were as accurate and apple-to-apples as possible, as the thermal interface material included varies from manufacturer to manufacturer and will even be changed on the same product between batches, as many heatsink manufacturers choose to not invest a lot in this particular area.
Lets take a look at our temperature testing results under stock and overclocked conditions. All heatsinks are tested with fans at 100%.
The Cryorig R1 Ultimate performs on par with the Corsair H100I GTX with our I7 4790K running at stock speeds and the motherboard set to Auto CPU voltage. The H100I GTX is considerably audible and definitely noticeable when the fans are running at 100%, whereas the Cryorig R1 Ultimate is barely audible when you are a few feet away. Given that the performance is right in line with what the H100I GTX provides, we are very impressed, as the H100I GTX offers very good performance and retails for $110, which is $20 more than the current price of the R1 Ultimate. Let’s see how the R1 Ultimate holds up under overclocked conditions.
Once we turn up the voltage and get the CPU set to 1.265V, the lower performance heatsinks begin to fall off and near the TDP of the I7 4790K. The R1 Ultimate and H100I GTX both keep neck and neck, with the R1 Ultimate topping out at 86 degrees, while the H100I GTX kept the CPU at 85 degrees. This is a pretty negligible performance difference and I’d consider the cooling performance between the R1 Ultimate and H100I GTX to be identical, though the sound levels of the H100I GTX are noticeably higher.
Keep in mind that the load temperatures we recorded under Prime 95 are a worse case scenario, as a system will never really reach the levels of stress put on by Prime 95 under normal usage. For example, after an hour of playing Rainbow Six Siege at our overclocked settings, we found our CPU topped out at 60 degrees with the Ninja 4 installed and fan running at 100%. The performance results achieved by the R1 Ultimate are simply amazing, though given the price, paired with the technology touted by Cryorig and sheer size of the unit, we are not totally surprised. The ability to perform on par with one of the better 240MM AIO units on the market speaks volumes for the Cryorig R1 Ultimate.
On the next page we’ll wrap this up and give our final words on the Cryorig R1 Ultimate.
