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 would of course like to see the testbed updated to have fan/s controlled by thermals, ie something like ASUS Fan Expert. Set for a target temperature and loads in the more realistic range of 15-150 watts. And of course when reducing voltage it should be via PWM and not simply reducing static voltage. The results should then be presented in temperature variance and noise levels/profile.MrSpadge - Monday, July 6, 2015 - link
Good suggestions. I hate those charts with "full fan voltage" and "fan voltage reduced to ..". What I really care about is "how silent can the cooler be for a given temperature / cooling performance?" And "which one cools better at similar noise level".It doesn't help much to see a strong fan with inbearable noise in those charts. Even if someone is interested in such solutions - wouldn't his question rather be "which heatsink performs best with this high-speed fan"? Which would again be something he couldn't answer from this data.
I know making noise based comparisons is difficult. But the raw sound pressure could be accompanied by some subjective remarks regarding the noise spectrum.

It would be interesting to see how the stock coolers compare to this high performance cooler. I wouldn't pay $80-100 just to see 5degrees improvement.Eidigean - Monday, July 6, 2015 - link
Chips big enough to need these coolers, such as Socket 2011, do not come with stock coolers.meacupla - Monday, July 6, 2015 - link
The stock heatsink cools great and is pretty silent with stock settings in a case with decent airflow, end of story.These kinds of $80 heatsinks are what you want when you overclock, but with the same or lower noise levels.
If you don't overclock, then a $20~25 heatsink can do a 5~20C improvement and keep the computer quieter at the same time too.

What are you, a shill for Intel? The Intel stock heatsinks are the absolute worst. Check out the graphs from this Anandtech article:http://www.anandtech.com/show/6830/cpu-air-cooler-...
Dead last in performance AND noise. Stock heatsink was greater than 30 degrees C hotter, and 20 decibels louder.

It says right there in the system specs used to test those coolers..."Intel Core i7-2700K overclocked to 4.4GHz @ 1.4V"
I'm surprised the stock intel heatsink was able to complete the tests.

no wait, look, it says the stock heatsink and a low profile heatsink failed on an overclocked i7.Like I said, stock intel heatsink, especially the one with a copper core, works great at stock speeds.

I don't know if the stock HSFs have changed since Sandy Bridge, but my 2500k would hit 98+ degrees and throttle under AVX loads with the pathetic little stock thing whilst sounding like a small tornado had developed inside my case (how is it that a 95w CPU comes with an HSF half the size of the ones they used to ship with 65w C2Ds?!)Whichever cheap tower cooler I replaced it with does the job just fine, though. It's been running like a champ at 4.5GHz for near enough 4 years now. (I think it's a Xigmatek SD1283 - I haven't even taken the side off my machine for over a year, those heady days of tinkering and yearly upgrades long since passed.)

What, no mention of the weight of each cooler? I think that's a rather important aspect.
