However, the CPU is not only the part of mainboard that needs cooling.There are components of on-board power switcher, memory sticks, and the platform chipset that might run pretty hot. Other thing that we notice is when the fans are running at 1600 RPM, we get far less gain from running push-pull configuration as the single set of fans are managing to dissipate a lot more heat from the radiator, so the closer the water temperature and radiator temperature to the ambient, the less improvement we’ll see from increasing the fan speed or doing a push-pull config. First, do whatever you are comfortable with, with respect to push versus pull, unless you have strong evidence for one approach over the other, since there is no definitive general answer. When the Noctua NH-U12S was equipped with one Noctua NF-F12 fan, the temperature when idle was 27°C. The CPU fan was still, on average, spinning at 900 RPM. Accordingly, I devised a simple test where the only changing variable was the number of fans used, or how they were mounted. Still, with the NF-F12 fans, very little noise. I asked myself the same question a while ago. The Valley Benchmark scores in this example is not important, however I can tell you that there was a 3 point difference in the final scoring. Nothing spectacular. This will create an accurate value which we can use as our platform when experimenting with this setup. Case: Cooler Master Masterbox Lite 5 RGB (modified) PSU: Seasonic Focus GX650 When running idle, the average CPU temperature was 24°C. So should the cpu fan push into heatsink or pull away from heatsink. Cyberpunk 2077). By There isn’t a large quantity scientific, detailed analysis on this subject out there, so I decided to try it out for myself. The Airflow though a rad is not limited to the push fans CFM, the pull fan increases the airflow though the whole system by inducing a low pressure zone behind the rad while the push fan induces a high pressure zone in front. If you are very interested in this subject, I have found one or two very well written explanations for the physical properties of airflow and how case pressure and case obscurance affect cooling performance. Dominic Moass I don't think push or pull really makes a difference to the cooling of the CPU, it has more to do with where the removed heat is directed after leaving the fan. Learn more about ASRocks new X99 Taichi at http://www.asrock.com/mb/Intel/X99%20Taichi/index.us.asp and Fatal1ty X99 Professional Gaming … Reinsert the fan and find the push pins. 99. Which do I recommend? Treat others as you would like to be treated. A template to show if it makes any significant difference. Forcing a Push-Pull scenario to an air-cooled CPU setup makes a difference. Pulling air through them is highly inefficient. In the real world, I’m sure that the results would be a bit more spread out, since different types of software and games are not a synthetic benchmark. Quite impressive temperatures, for an overclocked and air cooled CPU. It has compatibility for one or two NF-F12 fans, one of which comes as standard. Again, the CPU temperature increased, by not by much. Posted in Phones and Tablets, By Posted in CPUs, Motherboards, and Memory, By Learning from a mistake can be more valuable than not making one in the first place. $9.99 $ 9. Testing push vs pull vs push/pull, XPG previews new cases, RAM, SSDs, coolers and a gaming ultrabook for CES 2021. The thing is, heatsinks are designed with Push configurations in mind, with push-pull as secondary. I ran the Valley Benchmark test together with Prime95 to measure total system performance, to see how much it affected the ambient temperature in the case, causing other components to heat up. Again, the CPU temperature increased, by not by much. Wow, demonetized. Neither is this article written by a professional, which these in-depth guides about airflow are. Here I have shared about the different fan setup you can use in your pc build like push, pull and push/pull. The CPU is overclocked to 4200MHz, and all of the tests are executed with 4200MHz on the CPU cores. CPU compartment: No extra fan. High performance single fan CPU heat sinks almost always push air in rather than pull air out. Posted in Power Supplies, By What you want is for the pull fan to increase flow.. not match it. All other factors are still the same, which gives us an average reduction in temperature of 3°C. This is fairly normal air-cooled CPU temperature when running idle. Started 9 minutes ago When stress testing with Prime95, the average temperature on the CPU was 45°C. During these tests, the ambient temperature in the room was 18° Celsius. Pull up the push pins. Posted in Cases and Mods, By For the Hyper 212 LED, I used CoolerMaster’s Air Balance 120mm fans for this test. To get a temperature reading, I ran Prime 95’s (version 26.6) Small FFTs test for 10 minutes before noting down the maximum CPU temperature. I asked myself the same question a while ago. In theory, a Push-Pull configuration should normalise the pressure in the tower, and therefore reducing the resistance caused by obscured airflow. Push Pull on CPU Heatsink - Does it Work? However, the H60 allows me to use SL120s in push/pull configuration. More color variations in the product family. It’s the same thing, but in other words, I’m a bit lazy. Push, pull, or push/pull? However, the NF-F12 at full speed produces so much static pressure that even a single fan can push the air through fin-stacks with wide to medium fin spacing (such as the one of the popular Noctua NH-U12P heatsink) very effectively. Remove the fan. Introduction. To get accurate data from comparing various fan configurations, it was very important I devised a scientific and easily repeatable test. I'm finding the system quieter at idle with same idle temps (40s) and 20C cooler when running a gaming load (e.g. I have a fan on the rear of the tower that pulls air out and a power supply that consist of two fans, one on the bottom that pulls and one on rear that exhaust out as well. When running idle, the average CPU temperature was, When stress testing with Prime95, the average temperature on the CPU was, Now, the final test with Prime95 and Valley Benchmark. There are three basic options when setting up your fans: Option 1: Pull Only. The CPU temperature rose to an average of 52°C. The original LAN PC build log! JacobGrooms123 I used the included F12 fans for the Liquid Freezer 240. Yes, the NF-F12 can be used in push/pull setups. RAM: 2x8 3333 mhz DDR4 Trident Z. MOBO: MSI Gaming Pro Carbon AC. In my testing system, I’m using a Noctua NH-U12S CPU cooler. The average fan speed was the same as when only running with Prime95. Started 20 minutes ago They place fans on both ends of the airflow path, with one to push and the other to pull. As for the all-important CPU cooler, I decided to pick two – the Cooler Master Hyper 212 LED air cooler, as well as the Arctic Liquid Freezer 240 all-in-one liquid cooler. But if someone buys a brand new Hyper 212+ or a Hyper 212 Evo, I would suggest just using the one fan, as shown above it is pretty close in temperature. Fatty I will not go further than that, here and now. Started 18 minutes ago Turn the push pins clockwise 90 degrees to reset them. - MageTank 31-10-2016, You need to be a member in order to leave a comment. CPU: I5-8600k 5.0ghz. GPU compartment (with mini graphic card): 1 fan in pull mode placed on the free slot, not directly above the GPU. Of course, all fans can still be installed in push or pull configuration. 29. Find out what fan configuration is best for cooling down your radiator. Trying to get lower temperatures on idle is unnecessary, though. This time 1300RPM Push/Pull vs 1400RPM Push: The temperature remained the same during the entire experiment, but you should factor in a margin of error of +/- 1 degree Celsius. Push, pull, or push/pull? There isn’t a large quantity scientific, detailed analysis on this subject out there, so I decided to try it out for myself. ivanom4 Cooling, Featured Tech Reviews. A massive Thank You for reading! I took the temperatures during system idle, during a stress-test with Prime95 and during a stress-test with Prime95 and Valley Benchmark. Posted in Troubleshooting, By All three 120 millimetre fans are driven through a Fractal Design standard 5 volts, 7 volts and 12 volts fan controller. TechChuan Seeing this, if the fans are taken into manual control, we might be able to take some more degrees of that value. satellite999 These tests are carried out in a “best possible” scenario, with only the benchmarking and monitoring software running. It’s a marginal difference. Push-Pull on CPU Heatsink - Does it Work? Though, the difference between only one fan and having two fans is small. These values has been tested in a few different circumstances. Difference it makes, but not such a big one. I've always seen fans mounted to push air down onto the heatsink fins, not pull it away. Although, I would presume that it is a combination of the two, but mostly due to the ambient temperature in the case increasing. The RAM are two sticks of HyperX Savage, running at 1866MHz with timings 9-10-11-27 with a total capacity of 16GB. Now, the final test with Prime95 and Valley Benchmark. ... Meprotal 20 Packs Heat Sink Mounting Pins Plastic CPU Mount Clips & Push Screws for Intel LGA Socket, Cooling Fan, Heat Sink. As mentioned earlier, the reason for the rise in temperature is probably explained due to increased heat building up in the case, due to nearly the entire system being stress-tested. The CPU temperature rose to an average of, Moving strictly on to two fans. These values has been tested in a few different circumstances. In terms of actual testing, I performed three tests per cooler – obviously testing out push, pull and push/pull fan configurations. I've only seen pulling from a couple vendors like Dell, who have used a duct so that air is drawn past the heatsink fins and pulled through a case mounted fan at the back. If you are very interested in this subject, I have found one or two very well written explanations for the physical properties of airflow and how case pressure and case obscurance affect cooling performance. Not strange, since it's a GPU benchmarking program. Computer randomly freezes and all monitors go black, ethernet port locked at 10mb/s transfer speeds. 4.7 out of 5 stars 13. Press the push pins in the order shown to secure them. LinusTechTips. The 140 millimetre fans are PWM driven. This is a 5 minute video with all of my answers in it :)CA: ... Phanteks Thermal Solutions PH-TC14PE Blue CPU Heatsink Unboxing & First Look Linus Tech Tips. The pressure isn’t tested, hence why I will not guarantee a negative pressure in this case, since there are some areas of dust patches formed around some of the nooks and crannies inside and outside the case. Turn the push pins with a flat bladed screwdriver counterclockwise 90 degrees to release them. It's the same argument with smoothness. Here's an episode that we've been asked to do for quite some time. Upgrading PSU, do I need to replace the cables? BardiaMGTGC 7:41. Plug the fan connector from the fan header. And air should push down over your GPU and CPU from their own fans, and will push out the sides of those fins naturally. The CPU fan span at an average of 900 RPM. Powered by Invision Community. GPU: GTX 1070 ti EVGA SC Gaming. Very little of this is necessary to know in order to understand this small experiment. Push Pull on CPU Heatsink - Does it Work? As for the all-important CPU ... much difference whether you are using a radiator or a more typical heatsink ... testing out push, pull and push/pull fan configurations. At this bargain price it’s obviously not going to be the quietest of coolers, and at full fan speeds there’s no getting around that it’s rather noisy. The fan was, on average, spinning at 500 RPM. Neither is this article written by a professional, which these in-depth guides about airflow are. I thought that the reason they did this was to break up that boundary layer air and get the airflow closer to the heat sink itself. Started 1 minute ago Though, my averages are not as in-depth as those. GeForce GTX 560 Ti Twin Frozr II vs Reference Heatsink Cooler Linus Tech Tips. When stress-testing the CPU with Prime95, the average CPU temperature was 50°C. Most importantly, however, any test would have to be relevant to the average consumer – so using a £5,000 custom watercooled PC would not have been the smartest move, for example.
