Benchmark Results: Noise And Acoustic Efficiency
Single-fan coolers have the lowest noise at any given speed, since each doubling of identical sound sources adds an extra 3 db to the reading (in audio theory). That same theory explains why Arctic Cooling and SilenX’s mid-speed individual fans take second and third place in silence, ahead of Zalman’s three low-speed fans.
We’d consider anything below 30 db in open air to be quiet, mostly because we use quiet cases to cut back on ambient noise even more. True seekers of silence might settle for nothing less than Thermalright’s Archon, however, even though it doesn’t fit our motherboard properly.
The Archon SB-E is so quiet, in fact, that it tops our Acoustic Efficiency charts, in spite of its mid-pack thermal performance. At the other end of the chart, the SilenX EFZ-120HA5’s cooling performance can't compensate for its second-place noise level.
On a side note i wish the "ZALMAN CNPS9900MAX-R" was reviewed as well considering on newegg it is compatible with LGA 2011, and I've been eye balling that one since it came out for my next build.
I've heard nothing but great things from CM's Hyper 212+ and Evo variants. Might I add the other powerhouse in affordable cooling, Thermalright's TRUE Spirit 120 for just about the same price. It seems the Hyper 212+ and TRUE Spirit have fallen off in Heatsink/Fan comparison charts despite kicking some serious ass against there competition price rise, and can even hang very well against high-end coolers costing 2-3 times as much.
I realize you have to compare modern products to modern products for the sake of it, but just a FYI for those not familiar with the cooling scene. Don't ever count out a product that first debut 2-3 years ago, they can still hang, the good ones at least.
Water cooling is a lot more expensive and a lot more complicated. Water cooling systems are not maintenance free and always add the risk of a leaking pipe.
$80-$90 is a small price to pay for getting a quieter PC without resorting to water cooling.
Noctua NH-D14 weighs 900g without fans and it did 45c at full load.
900g/45c= 20.00 efficiency ratio.
Panteck PH-TC14PE weighs 970g without fans, performing at 46c.
970g/46c= 21.09 efficiency ratio.
CM Hyper 212 EVO Weighs 580g with fan, performing at 51c.
580g/51c= 11.37 efficiency ratio.
Ideally, the lower the ratio, the more efficient a cpu cooler is. Other charts count as well when making a final decision.
I checked newegg and amazon
seems like a good replacement for my sunbeam core contact heatsing
By that logic, having no cooler at all is the most efficient... 0g/200c= 0 efficiency ratio. And a dead CPU.
Also, the higher the temperature (Bad), the lower the ratio, which doesn't make sense.
You would also need to use the ambient temperature delta rather than the absolute temperature in any sort of ratio for the results to be meaningful.
I think that the majority of people don't care how heavy their cooler is, only about the price.
I am not saying that i need mass to make my decision. And i agree that surface is important. All i am saying is that i want to see cpu heatsinks to be more efficient or equal at cooling with less metal.
