Best is a bit of a misnomer, The Macho RT is in the top echelons, with the D15, D15S, R1 Universal and is indeed a bit quieter but performance is essentially on par with the rest of the top tier coolers.
If i don't keep the D15 people bitch, If i don't keep the R1 people bitch, If i don't have a Corsair AIO people bitch. Heres the thing. I review hardware, I cover content in depth and test the maximum possible performance these coolers are capable of.
I am not here to please everyone. Simple fact is Thermalright is not as popular as Cryorig or Noctua, and if my test bench only has high end products on it then its a worthless comparison. Considering each cooler takes 4-6 hours to rebench to get a base line setup and I have to test and restest the majority of coolers when dialing in overclocks. To make sure that I hit a realistic daily OC that stresses the coolers but isn't so absurd that nothing can pass the test. This means each new system requires a rebench that takes about 100 hours of my time.
Sure I could be a dick just half-ass the results but I choose to deliver what I actually find. Considering I also have to Could I do more? sure but I start with ten while most reviews use 2-3 or compare only to stock. So again I tend to pick a few coolers. Example Latest test bench started with 10 rebenched coolers, Including:
2x 360 mm AIOs (EK-MLC and Corsair h150i pro)
2x 240 mm AIOs (Aerocool P7 and Fracal Celsius S24)
3x High end Air (NH-D15 / NH-D15S / R1 Universal)
2x Mid range (NH-U12S / Thermalright True Spirit 140D)
2x Entry (Cryorig H7 / Cooler Master Hyper 212X)
That was in March of 2018, with the rebench being 10 coolers + 1 that was reviewed. since then thats been expanded to 27 coolers.
So you tell me when i constantly get shit for not including someones favorite cooler where do I draw the line? When it comes to running useless tests (idle temps) where do I draw the line? Can you test all coolers with the same fans? Can you rebench it with X fans? Can you test it with a different orientation?, Can you test it with a lower voltage? Can you test it with PWM only?
If people want more coolers in the charts at a rebench fine but they need to give up other things to keep time constraints down so no more installation coverage, no more time wasted on idle temps etc (idle temps alone waste 45 mins of my time per cooler review)
I will leave this bit of sage wisdom don't take it personally but:
I can only please one person per day. Today is not your day, Tomorrow doesn't look good either.
