Cryorig R1 Ultimate CPU Cooler Review

September 15th, 2014 Mike Leave a comment Go to comments

 

On with the CPU cooler round-up we go and the next in our alphabetically categorized line-up is from a pretty new company that I’m sure will send a chill through the air cooling community. It also happens to be their first product to hit the market, but can the Cryorig Ultimate R1 hit the ground running?

So what do we know of Cryorigs maiden cooler? Well, the R1 Ultimate features a dual-tower design which comes accompanied with two XF140 140mm cooling fans, DirectCompress™ Soldering (a new soldering technique), optimised fin design to improve heat displacement) accelerated air exhaust (each tower stack is separated into two sections. One with a low density fin stack and the other high), Jet Fin Acceleration System™ (to move air though the heatsink faster), Heatpipe Convex-Align™ System (to allow more heat pipes in a given area and to help them function at their maximum TDP capacity), HPLN™ (High Precision Low Noise Bearing, used in conjunction with acoustic vibration absorbers to help dampen vibration and noise), as well as the MultiSeg™ (a quick mount system that allows for a fast and firm installation).

I don’t think I’ve ever heard of a more complex or feature filled CPU cooler in all my life. The Cryorig marketing guys must’ve had a nightmare pushing these! 😉

Let’s take a closer look!

 

cryorig logo WHO AND WHAT IS CRYORIG?
CRYORIG was officially founded in 2013, but took several years in the making. We began our journey right at the start of the first decade of the 2000’s. During what was the most prosperous age of PC DIY and Overclocking. Members of our team have either worked directly or indirectly with brands such as Thermalright, Prolimatech, Phanteks and many more. We ourselves are overclockers and PC modding enthusiasts, with a passion and drive to strive for improvement. With direct knowledge of manufacturing and design as well as holding multiple patents under our collective belt, we decided to make a name for ourselves, and that name is CRYORIG. So what is CRYORIG exactly? CRYORIG is about making the coolest rig possible.’

The front of this large box is predominantly white with a the Cryorig brand name in the top left and a black and blue sticker, the sticker has the company logo, model name, colour and brief (see below) on the cooler inside l. There is also a massive picture of a cooler which wraps around to the right, which looks rather nice with its white heatsink shrouds, sadly this isn’t the R1 Ultimate we are reviewing today, but the R1 Universal (this isn’t a bad thing of course, just everything looks cool in white 😉 ).

The R1 Ultimate Dual Tower Cooler is the apex of air cooling innovation and design, with two XF140 high performance low noise fans.’

The reverse is nice, simple and black. It features some technical drawings of the R1 Ultimate with its dimensions, heatsink and fan specifications, as well as a comprehensive list of motherboard compatibility.

The right follows the wrap around cooler, has the same styling as the front and gives us the key features of the R1 as follows:

Compact and Compatible, The Dual Tower That Fits
Designed with compatibility in mind, the R1 fits am extremely wide range of cases and mainboards, and compliant with both Intel and AMD Design Guidelines.’

5 Step Easy Installation, Get Started in 5 Minutes
Featuring the MultiSeg™ Quick Mount System, installation is fast easy and reliable.’

twin tower heatsink provides more heat dissipation area
Dual high performance low noise PWM fans with proprietary Acoustic Vibration Absorbers guarantees a smooth and silent ride’

Whilst on the right we once again have a black background with a feint grey sketch of an R1 cooler, the Cryorig name in the top left corner and a rather large shiny silver R1 logo in the middle (yep, it’s silver and yet another reflection of me).

Hidden inside the box is another two boxes. Within the top box is all the fixtures and fittings, whilst in the larger box underneath is the R1 Ultimate heatsink with both XT140 fans pre-fitted. The general content presentation is excellent, both boxes have a break down of the components inside. The smaller box is especially noteworthy, once it slides out of its sleeve it acts as a tool tray with individual compartments for fittings, all of which are seperately wrapped (per system mounting system) and labelled. The box also contains a large tube of CP9 High Density CRYO Paste (yep, thermal paste), where any other CPU cooler I’ve used in the past would have a small single use tube. There’s also an alcohol pad for cleaning off your CPU and cooler prior to installation, a long handled Philips screwdriver (take a look at the photo below, it has the Cryorig name on it!), a product registration card within a foil wrap and fitting instructions. Cryorig have really gone that extra mile here!

R1 ULTIMATE

  • Research in Performance
  • Perfection in Details
  • The Apex of Air Cooling Technology
  • Full Contact Enhanced Performance
    Patented DirectCompress™ Soldering, increases the actual contact surface between the heatpipe and heatsink fins. DirectCompress™ Soldering has up to 10% more contact surface compared to traditional soldering, and the more contact surface the faster the heat conduction.

    Spreading Out and Making Room
    On aluminum sheets, heat spreads out in a radial direction. By displacing the heatpipe alignment on the heatsink fins, our Heatsink Displacement Optimization™ allows for better and more evenly spread heat conduction on the fins compared to traditional linear alignment.

    Accelerated Air Exhaust, The Faster the Cooler
    The individual tower stack is separated into two sections, the loose air intake and the high density exhaust section. By the laws of fluid dynamics, the increase in fin count in the exhaust section squeezes airflow and increases exhaust air speed. The increase of airflow speed in our Jet Fin Acceleration System™ allows heated air leave the tower faster.

    Optimized Heatpipe Positioning, Total CPU Coverage
    The R1’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.

    Kill the Noise, Silence is Cold
    Acoustics are just as important as performance. That’s why the XF140 140mm fan integrates acoustic optimizations. The XF140 features our High Precision Low Noise (HPLN™) Bearing and the detachable Acoustic Vibration Absorbers that give the fan a snugger fit while canceling vibration and noise at the same time.

    Patent Pending “MultiSeg™” Quick Mount System
    Patent Pending “Multiseg™” Quick Mount System providing an all in one solution on Intel platforms, CRYORIG’s MultiSeg™ Quick Mount System allows for a securer and firmer installation within minutes.

    First Impressions

     

    After a surprising and rather pleasant unboxing experience, it’s time to take a closer look at the Cryorig R1 Ultimate. It’s another heavy CPU cooler weighing in at 1282g and measures 168.3mm(H)x140mm(W)x142.4mm(L) including fans, which despite it’s appearance means it’s actually bigger than the recently reviewed Akasa Venom Medusa. It’s certainly a looker though (despite my slight disappointment, I thought the heatsink shrouds would be white and not black 🙁 ).

     

    Cryorig Ultimate R1 - front Cryorig Ultimate R1 - side fan

     

    The Cryorig R1 Ultimate is boxed with both XF140 pre-installed (you’ll see why later 😉 ). As a result pretty much all you can see from the front is a massive 140mm fan. The XF140 fans feature integrated acoustic optimizations including High Precision Low Noise (HPLN™) Bearings and Acoustic Vibration Absorbers on each of the eight mounting points. The AVA also give you then benefit of a tighter fitting fan, so should help prevent noise and help airflow at the same time. Otherwise aesthetically it looks uncomplicated and good. The matte and gloss black with grey go quite nicely with the Cryorig logo in the dead centre of the fan hub.

    From the side we can see quite clearly where the new Cryorig CPU cooler technology comes in. Apart from the two XF140, we can see the two gloss black heatsink shrouds (theses aren’t just for looks. They help direct the air flow through the heatsink stacks and also act as mounts for both fans). You can of course remove the shrouds if you should choose, which will reveal the twin fin stacks. Both of which feature dual stacks themselves! The front stack is bare aluminium and features less fins, allowing air to enter the heatsink faster (courtesy of the XF140s of course), whilst the rear black stack is more densely populated. This gives a larger area of dissipation, but also increases the exhaust air flow speed. These new approaches from Cryorig should help make the R1 Ultimate one pretty cool customer.

     

    Cryorig Ultimate R1 - top Cryorig Ultimate R1 - bottom

     

    Up above and the bit you’ll most likely see (unless in an MITX build), is pretty much a less complex and cleaner view of the side. The heatsink shroud lacks the fan mounts that feature on the sides and as a result are slightly bigger and more fluid, so where better to put the Cryorig logo? 😉

    Underneath you can clearly see the base, this is C1100 Pure copper nickel plated and slightly textured to allow better thermal paste adhesion (this should help to get rid of any air pockets and offer better heat conduction). Other notable features are the fixed plate with sprung fittings of the MultiSeg™ mounting sytem and the configuration of the heat pipes. The rear stack has them equally staggered instead of all in line, this is part of the Heatpipe Convex-Align™ System, each heatpipe which functions to them reach maximum TDP capacity.

    The Cryorig R1 Ultimate is very well made, looks good and is subtle enough to work well within any rig out there (assuming it fits 😉 ), the XF140 fans feature some quality nylon braiding while according to Cryorig and the specifications, probably the most advanced and feature packed CPU air cooler on the market. So it sounds very promising, let’s see how it performs in the pcG test rig!

     

    Hardware Installation

    The Cryorig R1 Ultimate like most CPU coolers today, features a variety of fixtures and fittings to suit most CPUs. What most coolers don’t feature is a nice little cardboard tool tray with sections for each of the itemised fittings (suddenly life just got a whole lot easier!). So out comes Multiseg Quick Mount System and appropriate fittings for the LGA1150. The Multiseg backplate is similar to that of the Akasa Venom Medusa, in that it features four sliding bolts (for the i5 4670K we need the central one). Once positioned, this is then lined up to the motherboard, the four screw pillars are then screwed on each upright bolt to hold the plate in place (there is a slight looseness once in position, this is nothing to worry about as once the heatsink is installed will tighten up), the Intel mounting bars are then placed horizontally and capped with the screw pillars. Both the CPU and baseplate are given a quick wipe over with the included alcohol pad (to get rid of any previous thermal paste and my greasy finger prints), the CP9 Cryo-paste is then applied to the CPU and Cryorig R1 Ultimate lined up and situated in place. Then sudden panic sits in as I realise I haven’t removed the fans to screw the cooler down (bugger!). Of course this would be a minor problem if the R1 Ultimate didn’t have a long narrow Philips screwdriver included in the kit, or if the rear part of the front tower didn’t feature two channels in which you can screw through! ;).

    So now the Cryorig R1 Ultimate is in place, what next? Well despite me harking on about the Akasa Venom Medusa mounting system being brilliant or the Cryorig Multiseg quick mounting system being faster and better, there is a small issue with RAM clearance……. You see with the front XF140 installed, both DIMM slot 1 and 2 are covered and although the front fan is height adjustable, the heatsink shroud only features two mounting points for two different heights. These being 30-35mm (ie low profile or no RAM at all). The HyperX Beast are 46.41mm high which would mean losing the first of the two DIMMs. So after wondering off and sulking a while, I had a sudden epiphony! Why not fit the front XF140 on the back of the R1 Ultimate, leaving all four DIMM slots free? After all it can’t have a hit on performance can it???

    After a little hiccup and a genius workaround (ok, it was obvious simple, but I was tired ok?), the XF140 are hooked up to the PWM fan splitter and plugged into the motherboard. All incredibly simple (eventually) and surprisingly quick. We best get the Test Rig on and take some benchmarks!

     

    Testing Methodology/Setup

     

    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 help with fan speed accuracy we use SpeedFan whilst using MSI Command Center to adjust the fan speed. 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 i5-4670K CPU at the following frequencies: 3.4GHz (Stock), 4.0GHz (using MSI OC Genie, shown in the picture below) and 4.5GHz (using Intel XTU(Extreme Tuning Utility), also shown in the pictures 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 with all case fans unplugged to isolate the sound in question.

    Hardware Performance

     

    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 both Cryorig R1 Ultimate fans also set at 100% (XF140 1300 RPM (±10 %).

    Raijintek Themis 100% 19.00 60.75 41.75 47db

     

    Ok, that’s a bit of a shocker! Despite the i5 4670k only being at the stock 3.4GHz. The Cryorig flies to not only the top of the air cooler chart, but also above both the EKWB L240 water cooling kit by a full 1.00C and despite the XF140 at their fastest setting only knocks out 38db! For a first time effort from Cryorig this is certainly impressive already.

    We best take a look at how it performs with a little OC.

    Scythe Tatsumi 100% 24.00 72.75 48.75 32db

     

    As the results above show, the R1 Universal is still top dog amongst the CPU air coolers and runs the overclocked i5 4670K 1.75C cooler than our previous king, the Akasa Venum Medusa.

    Can it cope with a slightly higher overclock?

    Wow… I’m speechless… The Cryorig R1 Ultimate is our coolest air cooler by quite some margin, it cools a full 5.00C more than the Akasa Venom Medusa! Which is impressive, but when you consider under full load it even beats the EKWB EK-Kit L240 by 0.75C? That is something else entirely!

    As I’m a big fan (ha!) of silent rigs, I also ran this particular test with all case fans and the two XF120 on the Cryorig R1 Ultimate CPU Cooler at their very lowest. The max ave core temp did get a lot warmer at 74.00C, but the noise level dropped down to 29db. This CPU cooler really is something a little bit special. 😉

    Of course if this is still a little toasty for you it’s worth bearing in mind that while Prime95 is an excellent tool for testing the stability of any CPU overclock, it does this by running your CPU at 100%, in your average Gaming session you’ll most likely not even use half that. 😉

     

    Final Thoughts

     

    Here we have the Cryorig Ultimate R1 CPU cooler, which is the first Cryorig product seen at pcG, mainly because it is also their very first product!

    The Cryorig R1 Ultimate arrived in a simple, but stylish box that featured a rather large picture of a great looking black and white cooler, sadly this wasn’t the cooler inside The Cryorig R1 is available in two flavours. The Universal (white) and Ultimate (black). Both identical bar the heatsink shroud colour and the Universal has a narrower front fan. Within the box are two further boxes, one hiding the R1 Ultimate heatsink with pre-fitted XF140 140mm fans, the other containing a cardboard tool tray with all the fittings grouped, bagged and labelled individually. With the addition of a Cryorig branded Philips screwdriver, alcohol wipe and a large tube of CP9 high density CRYO-paste, the overall presentation is brilliant and Cryorig have certainly gone that extra mile.

    Despite my initial disappointment at not finding a white shrouded CPU cooler within the box, the black and grey R1 Ultimate is a good looking cooler with a build quality to match. The cooler is big measuring in 168.3mm(H)x140mm(W)x142.4mm(L) with a weight of 1282g (including fans) But with its Multiseg quick mount system, combined with the heatsink design, the Cryorig R1 Ultimate is one of, if not the easiest CPU cooler in the world to fit (short of a dollop of thermal paste and just whacking a heatsink on top of your CPU, it really couldn’t be much easier!). 😉

    This leaves the performance and to be honest, it has left me completely stunned! With our Test Rig CPU (Intel Core i5-4670K) at its stock speed of 3.4GHz, the maximum (core average) temperature hit a miserly 45.00C, colder than every other cooler we’ve currently tested with our current rig set-up. Of course this is at stock and nothing to shout from the rooftops about, but clock up the CPU to 4.5GHz and the heat jumps up to 65.75C, which is 5.00C cooler than the Akasa Venom Medusa, making it our best performing air cooler. That isn’t the whole story either! If you revisit our results, you’ll also notice that the Cryorig R1 Ultimate sits at the top of the chart and is even above the two water coolers we’ve tested, without getting any louder than 38db! Of course if that’s too loud for you, you can always dial back the fan speed to its lowest to produce 29db of noise, but the heat will jump up to 74.00 (which is still pretty damn good considering the trade-off).

    Of course it’s not all rosy… Being a massive dual tower cooler, the Cryorig R1 Ultimate in its out of the box configuration, totally smothers the first two DIMM slots in the pcG Test Rig, even when adjusted (this won’t be the same on every motherboard, the distance from DIMM to CPU socket is often different from board to board), but with a little bit of quick thinking (ok, may have taken me an hour or so) and placing the front fan on the back of the rear heatsink, everything worked perfectly. 🙂

    At approximately £50.00 even the price is damn good! In fact I think my only major grievance against the Cryorig R1 Ultimate, is its limited availability here in the UK. I really cannot recommend this cooler enough. I guess Cryorig hit the nail on the head when naming their maiden product the R1 Ultimate, because it is exactly that!

      Well it beat the EKWB EK-Kit L240 by 3C if your charts are accurate. Why didn’t you just turn the A/C up to match the coolest temperature from your previous tests? You have all sorts of different temps, and because of that, I find it hard to consider this article as accurate.

      To be fair Sylas the fact the Mike shows all different ambient temperatures for Coolers tested at all different times of the day and at different times of the year, I think lends his data a lot of Kudos… 😉
