Push/Pull still comes in at 85%+, and the highest Push radiator is only at 70%. Push trim: The fan(s) suck in the air as if it/they were installed on top the radiator and "push" the air across the radiator fins. "Push" vs "Pull", radiator airflow configurations. I was wondering if a pull setup would be better for my radiator considering i won’t have a lot of space between the fans and front of my case. I am currently building my second PC. 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. 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. Push/Push came out at 9.1C, which is barely any better than just one fan in push. Dominic Moass December 28, 2016 Cooling, Featured Tech Reviews When I built my first PC a few years back, I … A pull configuration mean less dust on the radiator, and more air flowing pulled out threw it, that being pushed out threw it. that's good to head because I really want the pull config purely for aesthetic purposes so I can have led fans and they were viewable thanks for the Pushing or blowing against itself, or the natural flow of air through the engine compartment is like … Overclocking & Cooling. Testing push vs pull vs push/pull. I disagree. I did both since I had extra silent panaflos around. New Listing 16'' Slim Fan Push Pull Electric Radiator Cooling 12V Mount Universal Kit BK New. Do yourself a favour and watch the whole video, he makes some fairly good points in my opinion. I hope that answers your question. Pull is slightly better, not significant but noticeable. it's more efficient for a fan to pull air through a radiator (especially with a shroud), so it would use more of the radiator's surface. Forums. Higher air velocity gives better heat transfer in the radiator. 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 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. Joined Jul 25, 2005 Messages 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. 0 comments. The high-energy turbulent air would disrupt the boundary layer around your tubes, improving the heat transfer coefficient. By EnergyEclipse March 31, 2017 in Custom Loop and Exotic Cooling. Push or Pull? Using radiator as intake on the other hand hardly effects GPU temps in game. 280mm radiator top-mounted, pull-exhaust configuration. Ascend to a level that respects your eyes, your wallet, your mind, and your heart. Yes more fans = more money. The push or the pull? Ascend to... the PC Master Race. Tech Support. Press J to jump to the feed. Forums. Back in the olden days the fan was mounted directly to the front of the engine, so pull was the only option. The air downstream of the fan will be more turbulent than upstream. This decision usually comes down to the most convenient place to mount the fan, rather than the most efficient design. Find out what fan configuration is best for cooling down your radiator. TONS of people have asked me about fan configurations for radiators and heatsinks. This works whether the fan is a pusher or puller. A Push/Pull configuration is where you have a 'radiator sandwich'. I have always used internal radiators with both a push and pull setup since 2000. But he didn't have a vent where it was pulling air from. 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. For a standard pass radiator, your not gonna notice any difference in push or pull, no matter what rpm the fan is. So the choice of push or pull (for me) really depends on where the radiator is in the case. 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. Thanks brothers. Generally, a radiator is a square, and fans are circular. As for best config, gentle typhoons are most effective in push. New posts Search forums. In this subreddit, we celebrate and promote the ultimate gaming and working platform. 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 … New posts. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. Testing push vs pull vs push/pull. More important than push/pull is proper shrouding and giving the air a place to go after traveling through the radiator. What is the difference that makes push better for this design scenario? 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. If you push the air is very turbulent and less likely to go through the straight fins. 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. With a push and pull I could reduce the noise better. Reason being, there isn't enough flow resistance to effect air movement. Which do I recommend? I have always used internal radiators with both a push and pull setup since 2000. Push means that the fan is closer to the inside of the case and pushes air though the radiator. Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. Improves the cooling to your entire engine bay, including Radiator, A/C System, Intercooler, Oil System, and Transmission. As a direct comparison, if you were to add a (matching) fan to a given AIO, they could develop greater static pressure working together. Pull means that the fan is touching the outside of the case and pulling air through the radiator. 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. Press J to jump to the feed. Push means air goes fan -> radiator, pull means air goes radiator -> fan. Application: Any Radiator Depending on Size. Dominic Moass December 28, 2016 Cooling, Featured Tech Reviews When I built my first PC a few years back, I … 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. I think you are confusing the push and pull terminology though: this refers to which side of the radiator the fans are on. 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. Menu. Condenser coils are the heat rejection part of a chiller so it acts like a radiator in this case. So in other words FOR EQUIVALENT NOISE – Push/Pull on ANY radiator out performs Push on ANY radiator. I had noticed in my previous shroud testing that push vs pull optimization was different depending on … 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. I have a dual 120 rad with 4 fans, two stronger ones on pull and the weaker ones on push. Using radiator as intake on the other hand hardly effects GPU temps in game. 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? Welcome to the official subreddit of the PC Master Race. Pull/Pull came out at 8.9C which a little better, but still not worthwhile. 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 vs Pull vs Push/Shroud vs Pull… I want to know which way to install the fans in my new build.
