But as said it depends on the fans and the radiators. In this subreddit, we celebrate and promote the ultimate gaming and working platform. 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. Difference between Push and Pull Fans. Forums [H]ard|Ware. Cooling System. Slim Design Provides Excellent Engine Bay Clearance. 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. Push vs Pull vs Push/Shroud vs Pull… Push means air goes fan -> radiator, pull means air goes radiator -> fan. Pull is slightly better, not significant but noticeable.

You can have a push pull with the case, but unless the fans on both side match, there’s gonna be inefficiencies. Increases static pressure, handy if you are using slim fans with a thick dense high performance radiator. Today we address the subject of push, pull, push-pull fan setups and how they affect different radiators and performance. The custom car world almost unanimously agrees that puller fans are more efficient, though there's not really any data out there. Put the faster ones pushing. : 2 pcs 7" Universal Fixed Stuck Installation Cooling Fan. Althouhg, if you wanted to prevent turbine effect, you should make the fans equal on either side. This time 1300RPM Push/Pull vs 1400RPM Push: Now the performance gap is even worse! 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. 30-40% on Push vs 85%+ on Push/Pull. 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. Higher air velocity gives better heat transfer in the radiator. When setting up a radiator, is it better to have the fans pull air away from the radiator, or push it into the radiator? I have always used internal radiators with both a push and pull setup since 2000. Link to post Share on other sites Neither relates to whether air is flowing into our out of your case.

And honestly, you get some pretty big diminishing returns when you do push/pull unless you are using a thick radiator (50mm +). A simple pull config works completely fine. 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. Push means that the fan is closer to the inside of the case and pushes air though the radiator. Using radiator as intake on the other hand hardly effects GPU temps in game. 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. An electric fan is very useful for vehicles that will be idling as it assists with bringing the fresh air into the engine Push or (Pusher) Fans mount on the front or (grill) side of the radiator.

As for best config, gentle typhoons are most effective in push. 6700K + 1080Ti. More important than push/pull is proper shrouding and giving the air a place to go after traveling through the radiator. Title: 7" Motor Engine Radiator Cooling Electric Pull Push Fan. 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. The air downstream of the fan will be more turbulent than upstream. I had noticed in my previous shroud testing that push vs pull optimization was different depending on … On the top push pull is sometimes tough without covering the top of the board but again always as a intake would be best.

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? Linustectips clearly reccomends a pull configuration. I was wondering if that was a viable choice. Push or pull makes no difference for the radiator. By EnergyEclipse March 31, 2017 in Custom Loop and Exotic Cooling.
