so I'm in the middle of setting up my my heat sink test bench this is going to be an X 79 platform with the GTX 580 as well as a vengeance C 70 case because it'll allow me to easily mount tall air cooling heat sinks dual radiator sort of all-in-one units like the H 100 as well as single radiator all in one unit such as the H 80 so the reason I'm setting this up is so that I can do some testing but while I was working on getting it going I pulled my H 100 off of my test bench and I noticed something that I wanted to sort of talk about so I get a lot of questions about should I use my fans in push you can see this is configured and pushed the blades are going to be rotating this way pushing air through the fins of the rail through the fins of the radiator out the other side or do I want my fans in pull which is where you'd flip them around and have them pulling air through the radiator so I don't know if I have an example of that yes see these ones are configured and push as well right here so they're pushing here that way or do I want to have my fans configured in push-pull so that's where you actually have fans pushing on one side and pulling through the other side of the rad in order to get well greater static pressure so the answer to that is actually not that simple so there's a few different things to consider so number one is performance for performance push or pull sort of if you have two fans on a dual 120 mil grabs either on this side or on the other side actually it doesn't matter this has been proven time and time and time and time again it's been debated until you know but you can debate it til the cows come home it's not going to change the fact that within margin of error it performs pretty much the same now when it comes to push-pull a lot of people are taking sort of I mean especially it was fashionable back in the day and I bought some myself to grab something cheap like y8 loon fans and then you know you do a layer of fans a layer of radiator a layer of fans and you can turn the voltages of those fans down in order to make them quieter even though you have more of them and you still get decent for minutes because the push-pull configuration allows more pressure to be built up by the fans now think about it this way guys if I take two fans that pocket here these two fans are a great example because of the way they're positioned if I take these two fans they're spinning at the same rpm they are capable of moving the same amount of air I take this heatsink out of the middle and I put them next to each other they're not gonna make the air go any faster like the actual CFM is not going to change what's gonna happen though is if there's resistance in the middle then they are going to get the benefit of helping each other to move air through the resistance they're gonna gain more pressure so people often ask me should I run in push-pull I say no the reason I say that is because there are so many fans on the market that are optimized for pressure such as the SP series from Corsair although those aren't necessarily my favorite not to his f-series or excellent safe gentle typhoons are excellent Silverstone air penetrators are excellent lots of good pressure optimized fans so you actually have all this pressure available to you by putting another layer of fans on the other side all you're doing is increasing the noise because remember you can't make the air go any faster in an open environment and if you already have a pressure optimized fan then you're good I mean if you had a non pressure optimized fan so this older not to an S series is a great example see that you could spin that at 10,000 rpm it would never generate any pressure because there's so much room for air to leak around the outside this is not a good radiator fan where as you see these nice broad blades on the SP 120 that is an optimized radiator fan so anyway long story short is push pull necessary I would make the argument no get a proper fan run in pull and there's a reason for that now when I was taking this radiator off of my test bench I was reminded why I normally configure radiators in pull done so you can see the dead spot in the middle where the fan hub is and then you can also see where all that dust has built up this system was actually running for about a year on the floor so that's why there is so much disgusting dust buildup on it so why do I always run radiators in pole configuration because once you've got a fan girl on there and a fan on here without actually taking the fan off it is impossible to clean the other hand whoops if you run a configuration like what I did with here let me just go over here exposure a little bit there we go if you run a configuration like what I did with my thermo chill here you can see this radiator was also run for a couple of years and hasn't been extensively cleaned because the fans on the other side my Silverstone air penetrators are pulling air through it so it's very very simple to just go through once in a while and you know blow a can of dust at it or use a vacuum to clean it off whereas if the fans in the way it is pretty much impossible to do it and you end up with something that looks like this and without taking the whole thing apart it's very difficult to clean now this is easy when it's on a test bench like this but what if it was in a case what if I had it configured in push with the fans on the bottom here blowing out how am I going to clean that it's like in the middle of a case whereas if the fans are right up against the edge of the case and all I have to do is get in there and kind of go just take the dust out of it and you are good to go so thank you for checking out my little sort of spiel about push-pull pressure fans non pressure
