Benchmark Results: Cooling And Fan Speed
Noctua and Zalman are in a dead heat at the top of our CPU temperature chart, and its here where many readers will remind us that Zalman’s cooler was mounted backwards (where its intake air might have been slightly warmer).
We’d give Zalman the benefit of the doubt if the fitment issue wasn't such a concern. Besides, some builders (and some cooler manufacturers) prefer to see chassis exhaust fans mounted as an extra intake, though we can only suggest doing that with cases that have extremely good top-panel exhaust.
SilenX’s temperature here has to be recorded as an estimate as a result of processor throttling. You see, the displayed temperature is an average for all cores, and this processor begins throttling at 90° C. Without the ability to achieve lower (and less realistic) ambient temperatures, we simply couldn’t keep the warmest core below its throttle point.
After gauging the amount of time it took to reach throttle temperature at various ambient temperatures, we looked at our rough time to ambient temperature curve and estimated that this cooler could only keep our system at full speed with a room temperature below -4° C.
Enermax's ETS-T40 similarly required an unrealistically-low ambient temperature of 20° C at these overclocked settings. We say unrealistic because we never cool our offices below 22° C in the summer, and even our coolest cases are slightly warmer inside. Yet, we can say with certainty that the ETS-T40 is at least good enough to use with this processor at a lower frequency, since it barely crossed the borderline while using a fairly high 1.40 V core voltage and a full CPU load.
Thermalright offers the lowest fan speed, so we expect it to give off the least amount of noise. Yet, the same product manages to achieve respectable cooling performance in the middle of the pack thanks to its fan’s enormous size. Unfortunately, those same larger dimensions forced us to move our graphics card to a different slot. Proper fitment is an important variable, so this small configuration change negates any possibility for a cooling-to-noise award. As with SilenX, Thermalright’s cooling performance is simply an estimation.
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.
