Dominic Moass December 28, 2016 Cooling, Featured Tech Reviews When I built my first PC a few years back, I … Though a lot of the replies here suggest that pushing is best, in my experience in the hvac industry, most air cooled chillers depend on the condenser coils being cooled using pulled air as a standard design. Pull is slightly better, not significant but noticeable. 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. I have always used internal radiators with both a push and pull setup since 2000. In this subreddit, we celebrate and promote the ultimate gaming and working platform. Yes more fans = more money. Ascend to... the PC Master Race. 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. 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. The custom car world almost unanimously agrees that puller fans are more efficient, though there's not really any data out there. So, if you want optimal overall temps, you should give your radiator fresh air. Having a plenum between the fan and radiator lets the airflow change direction more gradually, reducing both turbulence and noise. Pull trim: the fan(s) suck in the air as if/they were installed below the radiator and "pull" the air across the radiator fins. Which side is hard to clean? : 2 pcs 7" Universal Fixed Stuck Installation Cooling Fan. 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. The fan motors are usually mounted on top of the condenser coils. You can attach fans to both sides of the radiators. Push, the velocity of the air coming out of the fan will be higher than the air being pulled. Ok so it performs better and is quieter but what about money? They push fresh air that enters from the grill through the radiator. Menu. I put mine in push/pull, It is a complete pain to clean. I would get a reversible electric fan and have it switch every so often to clear debris like they do on tractors. 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. You can have a push pull with the case, but unless the fans on both side match, there’s gonna be inefficiencies. Tech Support.

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. Here's an episode that we've been asked to do for quite some time. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. 6600K + 1060. Howver, it did almost match the performance of the upgraded push/pull H100. Linus has a nice video for that question here. Cooling System. Ascend to a level that respects your eyes, your wallet, your mind, and your heart. Purely from a "getting the maximum amount of cool air flow" point of view. Difference between Push and Pull Fans. While for Push/Pull we tested three flow rates, the Push Only testing was conducted only at 1GPM in order to save time. Push Only Data vs Competition. 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. 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. Im planning abuild with 2 x 240mm radiators both are intakes. 240mm radiator front-mounted, push-intake configuration. Put the fan in the best place to mount the fan. Forums [H]ard|Ware. Dominic Moass December 28, 2016 Cooling, Featured Tech Reviews When I built my first PC a few years back, I … But he didn't have a vent where it was pulling air from. Let’s start with 750 RPM and see how it … So you can run the fans slower for the same cooling. When setting up a radiator, is it better to have the fans pull air away from the radiator, or push it into the radiator? Reason being, there isn't enough flow resistance to effect air movement. 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. 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 … If you are just talking about the fans on your case, most builders will … Condenser coils are the heat rejection part of a chiller so it acts like a radiator in this case. If we are talking about a standard car type radiator with lots of fins I think pulling is the correct way. Improves the cooling to your entire engine bay, including Radiator, A/C System, Intercooler, Oil System, and Transmission.

What is the difference that makes push better for this design scenario? Press question mark to learn the rest of the keyboard shortcuts. "Push" vs "Pull", radiator airflow configurations. 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. 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. Let’s double check that at medium fan speeds. Save up to 6% when you buy more. Pull/Pull came out at 8.9C which a little better, but still not worthwhile. That way you have pretty much undisturbed air which should go through easier. 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. Testing push vs pull vs push/pull. I want to know which way to install the fans in my new build. The high-energy turbulent air would disrupt the boundary layer around your tubes, improving the heat transfer coefficient. 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. As others have pointed out, the efficiency difference is negligible. This decision usually comes down to the most convenient place to mount the fan, rather than the most efficient design. Forums. If, however, the fans are behind the radiator and they pull the air through them, that’s called «pull». 30-40% on Push vs 85%+ on Push/Pull. 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. Edit: Yeah, you will be cooling the radiator more effectively, but the ultimate goal is to cool the engine. Push/Pull still comes in at 85%+, and the highest Push radiator is only at 70%. Push means that the fan is closer to the inside of the case and pushes air though the radiator. This was a killer quite setup. AKA have the 1150's push/pull on one section, and the 900's or 1450's push/pull on the other section. Pulling is definitely more efficient with HVAC equipment. Depends on what you're doing with it. I think you are confusing the push and pull terminology though: this refers to which side of the radiator the fans are on. Aids to Cool the Entire Engine Bay, including Radiator, A/C System, Intercooler, Oil System, and Transmission. I want to set the top radiator as intake and on pull. Put the faster ones pushing.
