Menu. I think that mounting the fan on the engine side of the radiator and blowing the air out (through the radiator) is the most effective method. Joined Jul 25, 2005 Messages Bottom line, if you want to run two fans, run one on either side of the radiator in a push/pull configuration. "Push" vs "Pull", radiator airflow configurations. Back in the olden days the fan was mounted directly to the front of the engine, so pull was the only option. "Push" vs "Pull", radiator airflow configurations. So in other words FOR EQUIVALENT NOISE – Push/Pull on ANY radiator out performs Push on ANY radiator. Thread starter CoW]8(0) Start date Sep 26, 2005; Sep 26, 2005 #1 C. CoW]8(0) [H]ard|Gawd. Push or Pull? As a direct comparison, if you were to add a (matching) fan to a given AIO, they could develop greater static pressure working together. Ascend to a level that respects your eyes, your wallet, your mind, and your heart. Menu. 6600K + 1060. Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. Thanks brothers. I have a dual 120 rad with 4 fans, two stronger ones on pull and the weaker ones on push. I don't know about fan aero... although I do know bearings and motors a bit, and would say for fan reliability, push is less heat on the fan motor's bearings. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. With a push and pull I could reduce the noise better. Im planning abuild with 2 x 240mm radiators both are intakes. Push, pull, or push/pull? Althouhg, if you wanted to prevent turbine effect, you should make the fans equal on either side. The fan motors are usually mounted on top of the condenser coils. Push or pull makes no difference for the radiator. They push fresh air that enters from the grill through the radiator. As for best config, gentle typhoons are most effective in push. Find out what fan configuration is best for cooling down your radiator. If you 'pull' the air you create a very small vacuum with (in theory) a lower heat transfer, if you 'push' the air you are adding the heat from the electric fan motor, making the temperature difference smaller. So my question is, I'm going to mount an electric fan on the radiator, which is side on to the mower (so not at the front like a car), am I better to have it pull the air through the radiator, or mount it on the other side and have it push it through? Brand New. Neither relates to whether air is flowing into our out of your case. : 2 pcs 7" Universal Fixed Stuck Installation Cooling Fan. New posts Search forums. ... Reddit Pinterest Tumblr WhatsApp Email Share Link. Noise level is just a little more than just 2 pull but the temp drop was like 3 degree less but it takes a lot for this system to warm the rad up. Push means air goes fan -> radiator, pull means air goes radiator -> fan. Push means that the fan is closer to the inside of the case and pushes air though the radiator. Condenser coils are the heat rejection part of a chiller so it acts like a radiator in this case. Good saying: when in doubt push out. Push, pull or push/pull after all? Exhausting air form inside the case through a radiator may give you a few degrees higher CPU temp in games because GPU makes a lot of hot air. This decision usually comes down to the most convenient place to mount the fan, rather than the most efficient design. 1/2. When the fans are placed in front of the radiator and air pushes through them it’s called «push». This would mean using any extra fans in push/pull makes little difference as the air is already flowing easily enough, rendering the extra fans redundant. Using radiator as intake on the other hand hardly effects GPU temps in game. The custom car world almost unanimously agrees that puller fans are more efficient, though there's not really any data out there. Overclocking & Cooling. Push or pull makes no difference for the radiator. Without going into boring details I'm about to built a different cooling system for my Walker MDD ride on mower, it's an older model that commonly suffered from overheating issues due to a non reversible fan and poor grass discharge design. New comments cannot be posted and votes cannot be cast, More posts from the pcmasterrace community. Howver, it did almost match the performance of the upgraded push/pull H100. Push Only Data vs Competition. Pull is slightly better, not significant but noticeable. ... Reddit Pinterest Tumblr WhatsApp Email Share Link. Improves the cooling to your entire engine bay, including Radiator, A/C System, Intercooler, Oil System, and Transmission. Do yourself a favour and watch the whole video, he makes some fairly good points in my opinion. If you’re putting the rad in the back/side part of the case, the front panel cables are a pain in the ass You can try to do exact calculations on the different heat rejections between the 2 orientations, but from the industry point of view, it will be negligible enough to justify changing the standard pull orientation. But as said it depends on the fans and the radiators. A Push/Pull configuration is where you have a 'radiator sandwich'. Most people doing that will do a push setup because of the mounts they have and also the backs of fans can look a bit ugly level 1 Core i7 4790 - GTX 1070 - 16GB RAM Pull means that the fan is touching the outside of the case and pulling air through the radiator. Forums. The push or the pull? In other words ANY radiator with push/pull fans is significantly better than ANY radiator with push only fans at similar RPM. AskEngineers is a forum for questions about the technologies, standards, and processes used to design & build these systems, as well as for questions about the engineering profession and its many disciplines. If a radiator is on the front of a rig it's easy to do a push pull on the rad being as an intake because one would already have places for case fans there. Testing push vs pull vs push/pull. Linustectips clearly reccomends a pull configuration. Title: 10" Motor Pull Push Fan. We hope to help you decide what kind of setup is right for you and to show the benefits of each. Having a plenum between the fan and radiator lets the airflow change direction more gradually, reducing both turbulence and noise. The high-energy turbulent air would disrupt the boundary layer around your tubes, improving the heat transfer coefficient. As others have pointed out, the efficiency difference is negligible. Depends on what you're doing with it. When setting up a radiator, is it better to have the fans pull air away from the radiator, or push it into the radiator? This is assuming the fan being used is a static pressure fan, since those are supposed to have a more focused flow for restricted air flow situations, like a radiator. Application: Any Radiator Depending on Size. Higher air velocity gives better heat transfer in the radiator. A pull configuration mean less dust on the radiator, and more air flowing pulled out threw it, that being pushed out threw it. Improves the cooling to your entire engine bay, including Radiator, A/C System, Intercooler, Oil System, and Transmission. Improves the cooling to your entire engine bay including oil cooler system and transmission. Now if the rad is like an DD extreme, or similiar, then I wouldn't be doing anything other then a push and pull set-up. Is it more efficient an effective for cooling performance to have a fan push air into a radiator or pull air out of a radiator ? I did both since I had extra silent panaflos around. When setting up a radiator, is it better to have the fans pull air away from the radiator, or push it into the radiator? This was a killer quite setup. Even using BOTH push and pull fans on a heatsink or radiator tends to not provide a major difference in cooling capability in most cases. Forums. I disagree. Purely from a "getting the maximum amount of cool air flow" point of view. hey guys setting up my first watercooled rig just had a question. 6700K + 1080Ti. I will mount the radiator at the front and use Noctua 3000 RPM fans to push air through the radiator and NZXT 2000 RPM fans to pull … A simple pull config works completely fine. 280mm radiator top-mounted, pull-exhaust configuration. Push/Pull still comes in at 85%+, and the highest Push radiator is only at 70%. So the choice of push or pull (for me) really depends on where the radiator is in the case. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. And put a shroud around it to make sure all the airflow is actually going through the radiator. TONS of people have asked me about fan configurations for radiators and heatsinks. It makes very little performance difference.What space you have, the position the rad is mounted in, and whether you want it to work as an intake or an exhaust should make the decision for you. While I have done radiator shroud testing before using more conventional 7 bladed fans, I wanted to do an update to both serve in shroud results and also give me some hands on time with my new radiator testing bench to see if there are any tweaks remaining before settling on a test method. Generally, a radiator is a square, and fans are circular. I have always used internal radiators with both a push and pull setup since 2000. I'll build a small circuit to reverse the direction of the fan every few minutes for 20 seconds or so to clear the grass anyway. Hey, I have got NZXT Kraken X73 for my new i9-10900K build; I have also ordered additional 3 Noctua NF-F12 iPPC 3000 PWM fans to do Push/Pull with the radiator. Press question mark to learn the rest of the keyboard shortcuts. Save up to 6% when you buy more. Testing push vs pull vs push/pull. Linustectips clearly reccomends a pull configuration. Ideally you should use it as an intake to get the coolest air. This works whether the fan is a pusher or puller. Edit: Yeah, you will be cooling the radiator more effectively, but the ultimate goal is to cool the engine. What is the difference that makes push better for this design scenario? Title: 7" Motor Engine Radiator Cooling Electric Pull Push Fan. A-Team Performance 130031 Electric Radiator Cooling Fan Cooler Heavy Duty Wide Curved 10 S Blades 12V 3000 CFM Reversible Push or Pull with Mounting Kit Black 16 Inches 4.5 out of 5 … Push or Pull => radiator <=, justification? If the fan has a cowling around the blade tips, air flow will be very similar but the issue may be where you are drawing the air from? Press question mark to learn the rest of the keyboard shortcuts. If, however, the fans are behind the radiator and they pull the air through them, that’s called «pull». I imagine that the air stream from the vehicle moving contributes to cooling the radiator, so the radiator still sees a turbulent flow of air when the car is in motion despite having a fan pulling air instead of pushing it. I was wondering if that was a viable choice. Using radiator as intake on the other hand hardly effects GPU temps in game. Ok so it performs better and is quieter but what about money? XT45 will provide 50 watts of cooling in push, 60 in push pull at 1000 rpm UT60 = 50/ 61 Monsta 80= 51 / 62 For each 120mm of radiator: XT45 will provide 61 watts of cooling in push, 74 in push pull at 1250 rpm UT60 = 63 / 76 Monsta 80 = 60 / 80 For each 120mm of radiator: XT45 will provide 68 watts of cooling in push, 82 in push pull at 1400 rpm I had noticed in my previous shroud testing that push vs pull optimization was different depending on … Forums [H]ard|Ware. "Push" vs "Pull", radiator airflow configurations. Which do I recommend? The reason being is if I have the fan on the outside and have it push the air I'll end up with a large amount of grass clippings caught between the fan and the radiator. Ascend to... the PC Master Race. While for Push/Pull we tested three flow rates, the Push Only testing was conducted only at 1GPM in order to save time. By EnergyEclipse March 31, 2017 in Custom Loop and Exotic Cooling. So, if you want optimal overall temps, you should give your radiator fresh air. But he didn't have a vent where it was pulling air from. I have used the above with 120,240 and 360 lenght radiators the average gain with both push and pull on was always less then 5c with 90 to 120 cfm fans. Push means that the fan is closer to the inside of the case and pushes air though the radiator. In stock form, with the two Corsair SP140L PWM fans, the H115i was MUCH louder than my H100 with the GT AP-15s. For a standard pass radiator, your not gonna notice any difference in push or pull, no matter what rpm the fan is. Dominic Moass December 28, 2016 Cooling, Featured Tech Reviews When I built my first PC a few years back, I … I hope that answers your question. Dominic Moass December 28, 2016 Cooling, Featured Tech Reviews When I built my first PC a few years back, I … AKA have the 1150's push/pull on one section, and the 900's or 1450's push/pull on the other section. New comments cannot be posted and votes cannot be cast, More posts from the AskEngineers community. Testing push vs pull vs push/pull” net, “Push or pull air across radiator fins?” Tom’s Hardware, “Liquid cooling – should it pull the air INTO the case or push out?” Tech Radar, “PC cooling mythbusting with Corsair’s fan and PC case experts” Ars Technica, “Push vs pull cooling” Option 1 is better, push or pull configuration doesn't affect temps at all but you want to put them to pull for easier radiator cleaning with regular vacuum cleaner. The pull is where it's mounted behind the radiator (usual position) and pulls air through the radiator and exhausts the air across the engine compartment. Put the faster ones pushing. Interesting that so many people are saying push when the vast majority of car radiators pull and the radiator for my home AC is also pull. I want to know which way to install the fans in my new build. As mentioned in a reply to another comment here, I will go ahead and add in a small push-pull test to the Nemesis GTR … Another factor could be the fan speed. If we are talking about a standard car type radiator with lots of fins I think pulling is the correct way. Let’s double check that at medium fan speeds. Cooling System. Here's an episode that we've been asked to do for quite some time. So you want to push hot air out. Difference between Push and Pull Fans. Reason being, there isn't enough flow resistance to effect air movement. Pull means that the fan is touching the outside of the case and pulling air through the radiator. We continue our guides that show differences in radiator performance depending on the speed of the fans, thickness, and FPI of radiators etc. Pull in push - pull config produces marginally (but some times important) help to push fans to do do their job. Let’s start with 750 RPM and see how it … Which side is hard to clean? I'll build a small circuit to reverse the direction of the fan every few minutes for 20 seconds or so to clear the grass anyway. I have used the above with 120,240 and 360 lenght radiators the average gain with both push and pull on was always less then 5c with 90 to 120 cfm fans. Forums [H]ard|Ware. Since most AIOs these days are between 25mm and 30mm, I would really just stick with the two best fans instead of trying to mount all four. Link to post Share on other sites I put mine in push/pull, It is a complete pain to clean. Pull/Pull came out at 8.9C which a little better, but still not worthwhile. Push/Push came out at 9.1C, which is barely any better than just one fan in push. Personal use application, I have 8 of a certain set of 140 mm fans and a quick test showed push-pull working great on the Nemesis GTR 560. I moved into a new case and had room for a 280mm so I decided to see how the H115i did. I test a 120mm radiator with push, pull and push pull configurations. Push vs Pull vs Push/Shroud vs Pull… This would mean using any extra fans in push/pull makes little difference as the air is already flowing easily enough, rendering the extra fans redundant. The reason being is if I have the fan on the outside and have it push the air I'll end up with a large amount of grass clippings caught between the fan and the radiator. A pull configuration mean less dust on the radiator, and more air flowing pulled out threw it, that being pushed out threw it. If you pull from over the engine then it may be worse than pulling fresh air in. Which do I recommend? Pulling is definitely more efficient with HVAC equipment. New posts. Cooling System. New posts.
