Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review
by E. Fylladitakis on July 6, 2015 8:00 AM ESTThe Cryorig R1 Ultimate
Cryorig is a company that popped literally out of nowhere in 2013. They claim to be a company founded by experts with previous experience at other well-known companies, who banded together to both make a name for themselves and to offer "the best of all worlds". The R1 Ultimate that we have here today is the largest, most powerful cooler that they currently manufacture.
We received the R1 Ultimate well packed in a large cubic cardboard box. Everything inside the box is well packed and the bundle is well presented. Cryorig supplies the necessary hardware for the installation of the cooler, a tube of quality thermal grease and a long shank L screwdriver tool. The screwdriver tool is necessary for the installation of the cooler, unless if there is a >170 mm shank Philips PH2 screwdriver available. They also provide a third set of wire clips, for the installation of a third cooling fan.
The Cryorig R1 Ultimate is a very large dual tower cooler. Plastic frames partially cover each tower and are used as supports for the two 140 mm cooling fans. The fans are preinstalled and removing them is not necessary for the installation of the cooler. Each of the two towers has two series of fins. The silver front half of each tower consists of 42 fins, the black rear half of 53 fins. The company claims that by reducing the spacing halfway across each tower, they can accelerate the air exhaust, forcing the hot air to exit the tower faster. It is a rather peculiar approach, as a uniform gap across the entire tower could achieve the same air backpressure/speed without the extra turbulence and noise that the transition will cause. Perhaps Cryorig's research showed that this approach somehow improves thermal performance, by either thinning the boundary layer or simply through higher turbulence flow.
No strange shapes or patterns here - the front of the towers is entirely straight, with Cryorig apparently thinking that trying to improve anything by shaping the intake side of the fins is a waste of resources. The rear of the fins forms a simple geometric pattern, not just to improve the aesthetics of the cooler but also to provide insertion points for the provided screwdriver, which needs to be inserted in the gaps between the center fan and the fins for the installation of the cooler.
Cryorig is using two 140 mm fans, rebranded to their own company logo. They appear to be the same as the XF140 fans that the company retails as well. Aside from the "high precision low noise" bearing that the specifications vaguely describe, not much can be found about the fans, other than that they have a maximum speed of 1300 RPM. According to the specifications of the R1 Ultimate, they are also rated at 23 dB(A). This however is a little misleading, as this is the rating of a single fan in standard test conditions (unrestricted) within an anechoic chamber, not of two fans installed on the cooler itself.
The copper base and heatpipes of the R1 Ultimate have been nickel plated to prevent oxidization, a common upgrade for high-end products. The contact surface is very smooth but not polished down to a perfect mirror finish. In order to save a little room and install a seventh heatpipe, Cryorig placed the seven heatpipes in a slight convex formation.

I fully agree with the Oxford Guy. I've got a NoFan CR-95C cooling my non-OC i7 4790K. This in conjuction with a couple of M.2 SSD-units, a passively cooled PSU and a passively cooled graphics card makes for a 100% quiet and rather powerful computer. To be on the safe side I've added a Noctua D14 which is configured to force air across all components when the motherboard temperature gets over 50 degC. I is almost never active, though. I've run the Prime95 "Torture Test" for prolonged periods but the CPU-temp consistently stays below 70 degC. In my opinion the NoFan unit is doing a splendid job, although at a price.Sivar - Friday, February 5, 2016 - link
Listen to Oxford Guy. I've used three NoFan models and they all work amazingly well...as long as your CPU's power consumption stays under 100W. If you use a 6- or 8- core i7, or if you overclock enough to hit the 100W envelope, fanless is not for you.Note that NoFan coolers benefit only slightly when a fan is used. They are truly built as fanless coolers from the ground up.

My HTPC has a G2120 with NH-U12P, HD5670 with Accelero S1r2, 64GB Samsung 830 + 1TB WD Black along with 80+ Plat 400W fanless PSU. Inside Lian Li A05N.Only fans being filtered intake Gentle Typhoon @~600rpm and exhaust Slip Stream ~400rpm.
Pretty overkill cooling wise. Could drop the fan speeds even further..
To answer your question, yes it can easily handle it provided there's a teeny weeny bit of airflow in the case.
Work rig has a HR-02 Macho with 800rpm Slip Stream cooling a 3770K@4.7Ghz/1.336V. Could run it fanless if I'd drop the clocks to say 4.3/1.1 or so..

It would simply be the ratio of surface area of the fins to the surface area of the top of the CPU making contact with the heat collector. The fans merely dissipate the heat more quickly over the same area.The advantage of the fans are to transfer the heat by convection to the outer environment more quickly than allowing the heat to build up closer to other components in the system.
If designed for heat transfer, the other components are likely to have been designed assuming an ambient temperature at a particular max level, say 100-130degF. As the delta Temp between the environment and the part generating the heat will increase, so will the heat flow by conduction.
Intent is to draw the heat as far away from the components as possible.
One problem in these designs is to get the heat away from the CPU, as well as the Motherboard components, as well as other components in the case, so the interior case temperatures don't approach the environmental max design temps of those components.
A disadvantage in building by components, is that the component manufacturers are likely to only design for their particular component or one they support.
A common problem in Data Centers is how to remove all the heat from the racks and equipment within them. ANSI/TIA 942 stds go a long way to coordinate between disciplines and trades to effect proper HVAC in the server areas, but even within the racks and cabinets, too many designs limit themselves to providing a temperature set point at different areas in the room, but fail to flow adequate air over the equipment to transfer the heat away from the local electronics environments.
Computer Room Air Conditioners (CRAC) units are notorious for being installed to remove heat, but fail to provide adequate ventilation (air movement) within the computer rooms.
Since most of the CRAC units use split systems (condensate lines in 1/2" copper tubing running through the wall to a condenser outside the building), The natural trend would be to incorporate a small heat exchanger using a CPU water cooling fluid as the secondary, and the chilled water from the condensate of a HVAC system as the primary chilled water to remove the heat.
I haven't shopped the Enterprise level systems. I wonder if such systems are commodities.

Interesting article, thank you! I especially appreciate the "Quick Conclusions", that's a great table.Shadow7037932 - Monday, July 6, 2015 - link
I wish you guys had included the Hyper 212+/EVO in the review as the base comparison.zodiacfml - Monday, July 6, 2015 - link
True. It should be the default heatsink to compare with. Now that majority of Intel's CPUs become low power and efficient, these dual tower designs seem overkill except for the unlocked multiplier overclocker or fanless PCs.Achaios - Monday, July 6, 2015 - link
Obsession with CM Hyper 212 EVO "Hypertwohundredtwelvetitis" is a disease also prevalent in Overclock.net. People go berserk over the 212, almost as if they have been mass brainwashed or mass hypnotized. To my best understanding, this mass hysteria is due to the fact that cheap "enthusiasts" may save up to the hugely important sum of $9.99 if they go with the 212 compared to other coolers for the wondrous performance gain of 0.8 Celsius. In other words, the mass hysteria with the 212 is because if you go with the 212, you will save enough money in the end to buy a pack of cigarettes and a can of beer.Nagorak - Monday, July 6, 2015 - link
Well every little bit counts, and to be honest I can understand why people would not want to spend $70-$80 on a heatsink. Getting a decent heatsink for $30-$40 makes sense for a lot of people. However, if you consider wasting money buying cigarettes to be reasonable, I can understand why you wouldn't put much stock in saving a few bucks.Achaios - Monday, July 6, 2015 - link
Given how many overclockers and enthusiasts actually use the CM Hyper Evo 212 in their rigs (as eveidenced at Overclock.net) I think that Zodiacfml's suggestion of the CM hyper Evo 212 being used as a baseline cooler is a good one and I recommend the OP to take it.
