Our full review of the avira update access denied U9S and D9L.
In most cases, anything below 15 dBA is pretty much the same, subjectively, because it will be masked by nunn's applied respiratory physiology pdf ambient noise, other components in your PC or other sources, such as the fridge in the kitchen, the distant drone of traffic a block away, etc.The SPL levels are divided into five 2-dB range increments, from 2019 dBA, to 1211 dBA.A few older models retired.All coolers are tested at full fan speed as well as at 1100, 900, 700 and 550 RPM (whenever possible).Market conditions change rapidly; we just can't track comprehensively around the world, so you're best to check on your own.The temperature rise above ambient, which tells us how many degrees above the ambient temperature the CPU is allowed to rise by the particular heatsink, is a specification that tries to elminate these other influences.Once you hone in on a particular cooler or two, it's best to study the original review for full details.Aug 21, 2006 - A handful of new coolers added.However, for this list, since most coolers come with their own fan(s it was decided that performance with the stock fan was most apropos.» 75336 reads, submitted by Lawrence Lee on Mon, 21:07.Cooling A new heatsink from Noctua is always worth more than a cursory glance, as this Austrian brand has become one of the most consistent producers of high performance CPU coolers in the past decade.Let us know if you find a cooler is completely discontinued unavailable.Given 25C ambient, that means 70C at the CPU.Aug 7, 2003 - Zalman 7000 Cu/AlCu, Scythe Kamakaze Arctic Cooling SS 4 Pro TC added.What's the data shown?1 2 3 4, next, update History, sept 21, 2014 - nzxt Kraken 61 added.(Best on top.) Keep in mind that the accuracy of temperature measurements is not better than, -1C, and a 1 dB difference is virtually inaudible.
The amount of pressure brought to bear on the interface also affects cooling.
The different noise levels are achieved by changing the speed of the fan(s we have several standard speeds (defined in RPM) that are used for almost every review, though sometimes, hardware/fan limitations prevent this.
