WEBVTT 00:00:00.199 --> 00:00:07.919 when it comes to cooling down a PC many enthusiasts and Gamers want to make sure 00:00:05.200 --> 00:00:12.040 that they've got some serious flow going on and no of course I'm not talking 00:00:09.880 --> 00:00:19.720 about your questionable hairstyle but about airflow but unlike buying say uh 00:00:16.440 --> 00:00:22.680 ceiling fan picking the biggest fastest 00:00:19.720 --> 00:00:29.640 spinning computer fan you can find is not always the best solution don't get 00:00:25.920 --> 00:00:32.800 me wrong fan sizes and RPMs how fast 00:00:29.640 --> 00:00:35.480 they SP are important but an element of 00:00:32.800 --> 00:00:41.440 fan design often overlooked by novice Builders is whether the fan is optimized 00:00:38.079 --> 00:00:44.120 for high air flow or high static 00:00:41.440 --> 00:00:49.920 pressure but what does that mean I mean can't any fan provide decent air flow if 00:00:46.960 --> 00:00:55.320 it spins fast enough well actually different fan blades are engineered to 00:00:52.120 --> 00:00:58.079 move air in different ways fans marked 00:00:55.320 --> 00:01:04.479 High airflow have one objective in mind to move as much air as POS possible 00:01:00.840 --> 00:01:06.520 through an open opening you might see 00:01:04.479 --> 00:01:12.280 the marketing for a high a flow fan focus on its CFM rating which stands for 00:01:09.479 --> 00:01:17.479 cubic feet per minute since a cubic foot is a measure of volume then this is 00:01:14.520 --> 00:01:21.680 indicative of the actual amount of air that the fan can either intake or 00:01:19.200 --> 00:01:25.119 exhaust or I mean if you think about it they're both going to be about the same 00:01:22.920 --> 00:01:31.079 on the other side of the coin are high static pressure fans static pressure is 00:01:28.560 --> 00:01:34.240 actually a concept in in fluid dynamics but don't worry too much you don't need 00:01:32.640 --> 00:01:38.880 a degree in physics to understand how this relates to cooling down your rig 00:01:36.079 --> 00:01:45.560 simply put High static pressure fans are better at forcing air harder through 00:01:42.159 --> 00:01:48.640 small spaces they may not move the same 00:01:45.560 --> 00:01:51.320 volume of air as a high air flow fan if 00:01:48.640 --> 00:01:56.880 they were both in sitting on a desk with nothing to push through but they 00:01:53.880 --> 00:01:59.399 typically blow air a little bit of air 00:01:56.880 --> 00:02:04.399 more strongly so when exactly do you want to pick one over the other well as 00:02:02.079 --> 00:02:10.520 a general rule high air flow fans are better suited to be used as case fans PC 00:02:07.640 --> 00:02:15.480 cases tend to be relatively open inside that is assuming you didn't cram a bunch 00:02:12.599 --> 00:02:20.480 of wiring into the front of it or like Snoopy or something meaning that being 00:02:18.239 --> 00:02:26.319 able to move lots of air at once can result in more effective cooling by 00:02:23.599 --> 00:02:31.599 contrast static pressure fans typically find their homes on things like heat 00:02:28.760 --> 00:02:36.920 sinks or Cooling radiators cooling components like these often have lots of 00:02:34.120 --> 00:02:42.800 metal fins that are used to increase the surface area of the device that needs to 00:02:39.599 --> 00:02:45.239 be cooled and to dissipate heat so to 00:02:42.800 --> 00:02:50.040 cool off the heat sink properly air needs to move through these fins with a 00:02:47.519 --> 00:02:54.440 sufficient amount of force in this situation to make sure that the amount 00:02:52.400 --> 00:02:59.599 of air moving through your heat sink is high enough you've got to have high 00:02:56.599 --> 00:03:01.680 static pressure but that doesn't mean 00:02:59.599 --> 00:03:06.519 that static pressure fans are a one-trick pony in fact they can often be 00:03:04.440 --> 00:03:11.319 a good choice for chassis fans if you've got some kind of an obstruction that 00:03:08.840 --> 00:03:16.799 might hinder airf flow otherwise for example many cases have hard drive cages 00:03:14.360 --> 00:03:21.120 directly behind the front intake fan so in this situation a static pressure fan 00:03:19.360 --> 00:03:26.040 can be more effective at getting the air through these small gaps they can also 00:03:23.799 --> 00:03:30.720 be useful if you have a case with very narrow vents on the front or a fan 00:03:28.760 --> 00:03:35.799 filter that's designed to filter the dust out of the air but is of course 00:03:32.519 --> 00:03:38.319 going to obstruct airf flow since many 00:03:35.799 --> 00:03:42.959 radiators and CPU heat sinks come with fans pre-installed it's a good idea to 00:03:40.879 --> 00:03:47.080 ensure that they're high static pressure if you want to get the best performance 00:03:44.920 --> 00:03:51.959 possible despite the fact that these fans are better for CPU cooling some 00:03:49.519 --> 00:03:56.840 manufacturers stick with whatever standard airflow focused fan for 00:03:54.760 --> 00:04:01.640 whatever reason to do your homework so you're getting the best performance 00:03:58.840 --> 00:04:05.640 possible of of your new cooling solution after all there's nothing quite like the 00:04:03.480 --> 00:04:10.280 feeling of seeing your temperature stay low after hours and hours of gaming that 00:04:08.400 --> 00:04:15.440 is assuming you didn't build your computer into the side of an 00:04:13.280 --> 00:04:22.680 igloo you got a whole other set of issues speaking of 00:04:18.759 --> 00:04:24.560 igloo
