Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review
by E. Fylladitakis on July 6, 2015 8:00 AM EST
Brace yourselves, summer is coming. As it happens every summer, the sales of advanced cooling solutions tend to increase this time of the year. This year a little more than usual, as many enthusiasts likely found the perfect excuse for an upgrade in light of the new Windows 10 release. Rising temperatures are a concern for both the casual user, who usually is just psychologically stressed by the higher temperature readings, and the advanced enthusiast, whose overclocked system is now facing random stability issues. And of course there are those who are simply annoyed by the increasing noise of their current cooling solution and are in need of something less intrusive.
Liquid-based cooling solutions are becoming easier to install and AIO kits generally are hassle-free, yet they are still not favored by the majority of the users. Their space requirements, increased complexity and price hold most people to simple air-based cooling solutions. After all, most advanced users are not quite convinced about the performance of AIO coolers to begin with, with some even claiming that air-based solutions can be as good or even better.
We have not had a review of simple air-based cooling solutions in a while here in AnandTech. With a new advanced testing setup and equipment, it makes sense to begin with roundup reviews, which present multiple current solutions and create a healthy reference database. However, there are thousands of air-based cooling products available and almost every one of them is designed for a specific purpose and target group. We had to start from a single category, therefore we simply requested from a number of companies to ship us whichever product they consider their best. Nine companies answered our call, alphabetically listed in the table below.
| Product | Fans | Fan Speed (RPM) |
Current Retail Pricing |
| be quiet! Dark Rock Pro 3 | 1 × 135mm 1 × 120mm |

| Thermalright Macho Zero | - | - | $65 (no fan) |
*As these coolers are not available in the US at the time of the review, these are the average retail prices in USD, excluding taxes.
**The Cryorig R1 Ultimate currently is available only through a foreign store registered in Amazon.com that ships from Korea. The current retail price is extremely bloated, far above the MSRP.

I know right? I was so looking forward to a W/C vs A/C comparison after an intro like that.Margalus - Monday, July 6, 2015 - link
why didn't you test these all with the same fan? Then we could see how the cooler performed independent of the included fans? Like the Thermalright, it comes with no fan, apparently you got a super quiet slow fan and put on there, but that isn't fair to Thermalright saying they are hotter, when it could be because it doesn't have the amount of air moving over the fins as others.Beany2013 - Wednesday, July 8, 2015 - link
Thermalright provided the fan, so they can't grumble at the results.trandoanhung1991 - Monday, July 6, 2015 - link
When you talk about ultimate cooling, you should've at least tested the True Spirit 140 Power Edition with a TY-143 fan, or the Silver Arrow SB-E Extreme. Those are the most interesting products from Thermalright, not the Macho Zero.Maybe as an addendum at some point? I'm very interested to see how the Silver Arrow and the 140 PE fare against the D15.

Apparently the Macho is what TR themselves chose to send AT, if the intro is accurate... Big /facepalm on their part. They probably have some of the best value coolers in the TRUE Spirits (I have the original Cogage version myself), and the Silver Arrow might've ranked up there with the Noctua and Phantek. The article did make me pretty curious about the latter tho, call me vain but the color choices are cool.Calculatron - Monday, July 6, 2015 - link
Thanks for doing a heatsink round-up. They are refreshing to see these days.It is a shame that Thermalright did not send in its top-tier performer. Then again, the Macho Zero is nothing to sneeze at. ~40C over ambient for a 340 watt load is still a good result. (Perhaps, instead, they could have thrown the TY143 performance fan instead? Har!)

I actually wish they would have sent 2 of the current fans so we could see if push/pull could push it up a performance bracket.rrohbeck - Tuesday, July 7, 2015 - link
I'd like to see the measurements all with the same fan(s) - whatever is considered "the best" fan. That would give an indication of how much you could get out of the cooler with aftermarket fans.'nar - Tuesday, July 7, 2015 - link
I wish there was more review cross-over with water coolers, these two camps seem to be at odds with each other. They never seem to be compared effectively to each other, so it is difficult for consumers to determine the "best" cooler for themselves. With Noctua getting up to $93, there are water coolers out there for less. I bought my Noctua NH-D14 for $75 and thought that was high for a HSF.I strictly used air coolers until I got an AMD APU, among them are several Noctua models. It was apparent to me that this CPU, after a bit of easy O/C, got hot much too fast for an air cooler to absorb. It would crash after just 4 seconds of starting Tomb Raider and the cooling fins were still ambient temperature. I tried three coolers including the Noctua NH-D14. Fan speed did not matter as the rapid increase in temperature exceeded the heatsinks' ability to draw the heat off the CPU itself. I would guess that it take anywhere from 30 seconds to a minute for the heat to actually get to the fins, so if your heat sink cannot "sink" the heat all by itself, no fan, for a full minute, then it has inadequate heat transfer and no fan will fix that.
I installed a Corsair H100i and that works very well. I had previously thought that any cooler with less surface area would have less cooling performance, but I have found that if you cannot transfer the heat to the fins, they make no difference. I think a Corsair H60 would have been fine now. I heard that water coolers were "better" and more efficient, but nobody ever explains WHY.
From this experience at least, it appears that water coolers have better heat transfer performance. Fan speeds and fins are secondary to that, as they do not matter until the heat gets to them. If they get hot, then low speed fans can easily remove that heat as higher temperature differentials generally allow for greater heat transfer. If you run high-power and high-heat for a long time, then higher fan speeds help.
How quickly can your test bench ramp up in power? Was that tested? Was that considered? CPU's can hit maximum power in nanoseconds, and crash in milliseconds. Only the base of the HSF would see anything from that event. I think this test is more academic, and not very relevant in the real-world with actual CPU's. It only tests for maximum heat generation over time, like when running benchmarks, not the dynamic nature in which CPU's operate for most useful loads. But then, that's just my perspective.

I agree with you. I think the heat transfer through heatpipes takes quite some time to get to the fins
