quote harbin91My previous CPU cooler DBX-B is rated to be at 20 dB and it was as loud as a microwave oven. I mean like pretty loud.How loud roughly, is 24dB and 31 dB? What are they equivalent to? I can hear the fans in my current PC (not too loud), but if I have sound coming out of my TV, then I cannot notice any noise from them.
quote Cryonicstatestrange...every formula ive read would imply the opposite with thickness. as a blade gets thicker, it should produce more lift, given that every other factor remains the same, because theres more surface area for air to be deflected from.quote hiigaranThin blades with a high pitch, angle or rake as some call it are designed to push more air, the fans with the wider blades and low pitch produce a higher static pressure. You can use a fan that has a low SP rating on a radiator with a low fpi count, but the more fpi you have the higher the SP rating you need to push the air through the radiator.one thing ive never had a definite answer on...those fan blade thicknesses. you have the thinner ones with more blades, then the thicker ones with fewer blades. whats the performance difference? its always been something thats confused me with things like the shape of propellers on planes and ships, with them being so different.
quote harbin91Yes sir!quote CryonicstateSo basically, static if there is an obstruction such as drive cages, but CFM if there isn't such as exhaust fans?quote harbin91You would want to use the high flow, but first look at where you intend to place the fan. Will it be pushing air through a hard drive cage then you would want to use the static pressure fan.On case fans, no PWM for me would be fine since I like my case fans to run maxed out all the time. Lack of PWM would kill it somewhat for me using it on the CPU.
Which is better for case cooling though? Static pressure or high airflow? Expensive for fans (or atleast seems expensive) but somewhat worth it. Would've been tempted to grab some Spectre Pros to match my case, but these are quite tempting aswell.
Hope they do a PWM version though for my CPU cooling. Assuming ofcourse that they'll fit in my cooler.
