what's up guys Jays $0.02 here and I'm gonna aim to make this one a fast one because I want to get to the point I'm tired of dwelling on this topic I've talked about it so much you would think that I would have already done this video but I'm an idiot and I never did today we're going to do two direct comparisons between a static pressure optimized fan and an airflow optimized fan on the same radiator on the same device with the exact same RPM settings running the same test with the same ambient temp to get tail we got a lot of constants going on here and we're gonna see once and for all what kind of differences there really are based on fan type okay so here's the setup I've got a EVGA GTX 1080 hybrid and I'm using that card because well it's an all-in-one loop on a graphics car they get hotter faster I can do this test more quickly and it's very very consistent and unlike CPU which is doing a lot of other random things but that's besides the point anyway it's got 120 millimeter all in one radiator in there it's a 30ml radiator so it's going to give us a pretty good example of what kind of temperature Delta's we're looking for your Delta or the difference between the two is what we're really after here now for the fans I've got two identical fans here well with the exception of the blade design they are both Corsair 120 millimeter quiet Edition fans so they're going to be running a max of 1200 rpm except one is an SP and one is an AF airflow and static pressure so we're going to do our first test here on heaven we're going to let the thing run at 4k until the temperatures equalize at a particular temperature and whatever that may be the max temp and then we're going to compare our baseline with the static pressure fan because that's the fan that people say you have to go with then we're going to slap on the air cooled or the airflow fan and we're going to see what the differences really are I have to make sure obviously with my thermometer that the room ambient temp is the same there's a lot of variables here we've got a Kevlar there's like highschool science alright enough talking let's get to it that was stupid transition okay so this thing's been running for a while now actually looks like we got a baseline of about 49 to 50 see it's kind of bouncing back and forth right there we might have actually hit 51 for just like a split second I'm going to check that now I know you guys probably can't see it too good it's actually in 4k now it's really small max temperature 51 like I said but it flattened out right at 49 50 49 54 9 feet and that's where it stayed so that's our baseline we're going to do now we're gonna do the exact same test with with with this pin that's how that's how it works so compare and contrast works if you guys are in high school and you do science class you note that okay should okay just do it now I've just started the test here with the airflow fan but the one thing worth pointing out and this isn't a surprise to me I expected this but one thing worth pointing out is one of the reasons why I put paper on these radiators like that is it gives you a visual representation of the amount of pressure coming through the fan and the amount of airflow so you can see kind of a comparison between the two if one if the paper is being pushed up higher with one fan and the other that means it's more airflow and you can see that with the AF fan the paper is not moving as far as the espy fan and they're both running at 1,200 rpm the running at their max right now but the question is does that equate to different temperatures well it's running and we'll come back at the end and we'll talk about the results okay our test has been running long enough here we've got a lock temperature of about 55 degrees Celsius it bounces down to 54 every now and then then comes back up to 55 and then there's a scene where the islands are kind of floating in the sky whenever that scene happens it pops up to 56 and then comes back down to 55 so if we compare the two that is obviously a temperature delta of 5 degrees Celsius if we look at the max with the little spikes in temps that we saw a 51 verse is 56 and we're seeing about 3 to 4 Celsius Delta between the average temperatures now on the surface that leaves a lot of room for argument that yeah static pressure fans are obviously better for radiators no one's ever argued that in fact they are optimized static pressure for a reason but the whole point of this here was to see just how much of a difference there really is now let's take a look at the setup here real quick to understand the results a little bit more we have a graphics card that was overclocked to 2088 megahertz max voltage and the memory was running at plus 400 so we're putting a decent amount of heat although the memory is not touching the cooling plate in this test I overclocked it anyway just for the hell of it that's what I do on a 120 millimeter radiator that's only 30 millimeters thick so we are already asking a lot of the radiator now if we were to take the radiator and make that a 240 red would have seen much closer results on the temperatures because radiator surface area is more important than the type of I think I just hit the mic this video is full of fail the radiator surface area is a bit more important than the fan blade design now obviously if you have a choice optimize it go with the right stuff at the start but I just wanted to put some people at ease that if they got the wrong fan they don't need to freak out they're not going to ruin their system you know if you want to know a little bit more about things like push pool because that's obviously the next question then check out this video right here I've already done a comparison of push pull and push pool on this exact same setup so you can see how that compares there's a lot of confusion when it comes to fans up I've done videos about fan setups and stuff I mean gosh there's there's so many videos about fans on this channel because there's constant debates over it but a lot of people get really caught up on this stuff and they really start to obsess over one little thing and they kind of miss the big picture anyway worst case scenario here tiny radiator hot graphics card running overclocked you saw we saw a max of 5c Delta on spikes and only about 3 C on our average temp that's not bad like I said if I put a 240 in here and put 2 SPS vs. almost did it again vs. 2 SPS and two air flows we would have probably seen only about a 2 degree difference maybe even one looks like I've got a topic for another video that's ok this this conversation will never die so we can just keep talking about it till the end of days alright guys thanks for watching as always I'll see you in the next video
