The airflow will have an easier time travelling though the cooling tower, easily said. satellite999 Pulling air through them is highly inefficient. I'm finding the system quieter at idle with same idle temps (40s) and 20C cooler when running a gaming load (e.g. Posted in Storage Devices, By When stress testing with Prime95, the average temperature on the CPU was 45°C. Please, if you see any obvious errors in the scientific data, or any other obvious fault, I’d appreciate if you helped me to correct it! - MageTank 31-10-2016, You need to be a member in order to leave a comment. An extra fan bracket is also included, so you can configure it to be push/pull if you wish. When running idle, the average CPU temperature was 24°C. Posted in Storage Devices, Linus Media Group I know typically we look at GPU thermals here but, the CPU has to "feed" the GPU or it's the bottleneck. Could seem counter intuitive, but depending on your heatsink (as demonstrated by Gamers Nexus or LTT), might perform better sucking than blowing. This time 1300RPM Push/Pull vs 1400RPM Push: When the Noctua NH-U12S was equipped with one Noctua NF-F12 fan, the temperature when idle was 27°C. I hope. well thanks for the read i guess. 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. BardiaMGTGC 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. Started 8 minutes ago For the Hyper 212 LED, I used CoolerMaster’s Air Balance 120mm fans for this test. More color variations in the product family. Both fans ran at the same speed, on average 300 RPM. This all has to do with the defined rules of nature, with heat conduction and so on. Again, the CPU temperature increased, by not by much. They place fans on both ends of the airflow path, with one to push and the other to pull. In total, six versions of the new P-series fans (P, P Silent, P PWM, P PWM PST, P PWM PST CO, BioniX P) will be available, each in 120 mm and 140 mm. In the system I used an Intel i7-5820K, MSI X99A SLI Plus motherboard, 16GB of Panram Ninja V DDR4, a Sapphire R9 285 ITX GPU, an OCZ Trion SSD and a Corsair RM750x PSU. Push Pull on CPU Heatsink - Does it Work? Posted in Cases and Mods, By After a while though, we reach the absolute point where we can’t deduct more units of temperature, with this setup, since the temperature is starting to normalise. I got the best Waifu a man could ever ask for Lieselotte Sherlock is my girl ( in my profile pic ), oh my god did this take a while to read, you could have just posted the pictures and said in about 3 lines what you did, but instead you wrought an essy.. well i wont complain because this is pretty well done. Good heatsink. Fatty Posted in Phones and Tablets, By Again, the CPU temperature increased, by not by much. And air should push down over your GPU and CPU from their own fans, and will push out the sides of those fins naturally. Would it be better if I had the fan on the backside of the heatsink, pushing air through it or on the front of it pulling air through? Posted in CPUs, Motherboards, and Memory, By The CPU in the system is an Intel Core i7-4820K, sitting on a Republic of Gamers Rampage IV Gene motherboard, which is a motherboard with X79, of which this system is based. When stress-testing the CPU with Prime95, the average CPU temperature was 50°C. All other factors are still the same, which gives us an average reduction in temperature of 3°C. Turn the push pins with a flat bladed screwdriver counterclockwise 90 degrees to release them. Push Pull on CPU Heatsink - Does it Work? Neither is this article written by a professional, which these in-depth guides about airflow are. Neither is this article written by a professional, which these in-depth guides about airflow are. The CPU is overclocked to 4200MHz, and all of the tests are executed with 4200MHz on the CPU cores. In my testing system, I’m using a Noctua NH-U12S CPU cooler. The results might vary in other systems than mine. This will create an accurate value which we can use as our platform when experimenting with this setup. Temperatures were 70.7C at load, not the coolest but nothing to worry about. Not strange, since it's a GPU benchmarking program. Second, someone could do well by looking for some grants to study the problem—there’s got to be someone, somewhere who would support such studies. Excellent job, Noctua! Seeing this, if the fans are taken into manual control, we might be able to take some more degrees of that value. It's the same argument with smoothness. Very little of this is necessary to know in order to understand this small experiment. Started 18 minutes ago The fan was, on average, spinning at 500 RPM. Trying to get lower temperatures on idle is unnecessary, though. 29. Yes, the NF-F12 can be used in push/pull setups. This graph below should show the values, slightly easier to read. The reason for this is that the actual CPU indirectly heats up. Cyberpunk 2077). That’s quite personal to decide. It’s the air, and therefore the airflow in the case becoming warmer, due to the GPU emitting more heat, simply. 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. Learn more about ASRocks new X99 Taichi at http://www.asrock.com/mb/Intel/X99%20Taichi/index.us.asp and Fatal1ty X99 Professional Gaming … I got the method from another test on Overclock.net. Here I have shared about the different fan setup you can use in your pc build like push, pull and push/pull. Turn the push pins clockwise 90 degrees to reset them. To get accurate data from comparing various fan configurations, it was very important I devised a scientific and easily repeatable test. The GPU is an Nvidia GeForce GTX 760OC from ASUS. Testing push vs pull vs push/pull, XPG previews new cases, RAM, SSDs, coolers and a gaming ultrabook for CES 2021. Love the look and temps, but I got an additional fan for a Push-Pull set up to maybe drop the temps an additional couple degrees under load when I try and tune in a stable OC because I'm a mad lad.. Which do I recommend? Though, my averages are not as in-depth as those. These values has been tested in a few different circumstances. These tests are carried out in a “best possible” scenario, with only the benchmarking and monitoring software running. Agreed there, it works the best for most cases! TONS of people have asked me about fan configurations for radiators and heatsinks. Remove the fan. These fans are designed for heatsinks and radiators specifically. Upgrading PSU, do I need to replace the cables? Press the push pins in the order shown to secure them. 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. Although, idle temperatures is nothing to brag with. Wow, demonetized. In plain English, the airflow through the tower will not be as affected by the cooling fins, since these cause resistance. 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. HDD: 1 TB 7200 RPM Seagate Baracudda, 1 TB 5400 RPM Samsung Spinpoint HD103SI. I think then that this could work as a benchmark. I used the included F12 fans for the Liquid Freezer 240. Ram is bugging? High performance single fan CPU heat sinks almost always push air in rather than pull air out. On average, the CPU temperature was, I'm starting to lose my mind nitpicking cases that I don't know what looks good or what I want anymore. It’s a marginal difference. Although, I would presume that it is a combination of the two, but mostly due to the ambient temperature in the case increasing. Posted in Troubleshooting, By In theory, a Push-Pull configuration should normalise the pressure in the tower, and therefore reducing the resistance caused by obscured airflow. I asked myself the same question a while ago. 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. Pull up the push pins. The NF-F12 fans uses Noctua’s FocusedFlow-technology, to have a better and more focused static pressure than other fans in the same category. Mack Shaun. pull cold air from the front push the warm/hot air out the back if possible. 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. Also, to see if this put a bigger stress on the CPU, causing it to heat up on its own way, rather than the ambient temperature in the case increasing. Find out what fan configuration is best for cooling down your radiator. December 28, 2016 alfrederson Perhaps, if your average CPU temperature is higher than mine, or you have a higher overclock, it might make a bigger difference, and a bit more sense. To replicate the day-to-day scenario, and to make full use of the case pressure, the side panel has remained on during all of these sequences of the experiment. Computer randomly freezes and all monitors go black, ethernet port locked at 10mb/s transfer speeds. 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. Push-Pull on CPU Heatsink - Does it Work? It’s when the temperature is rising that we find the important and interesting values. 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. GPU: GTX 1070 ti EVGA SC Gaming. A template to show if it makes any significant difference. Now, the final test with Prime95 and Valley Benchmark. 99. These values has been tested in a few different circumstances. GeForce GTX 560 Ti Twin Frozr II vs Reference Heatsink Cooler Linus Tech Tips. Posted in Power Supplies, By Started 17 minutes ago 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. Reinsert the fan and find the push pins. Started 24 minutes ago All three 120 millimetre fans are driven through a Fractal Design standard 5 volts, 7 volts and 12 volts fan controller. Which do I recommend? It's easy! This system has a presumed negative pressure. In other words ANY radiator with push/pull fans is significantly better than ANY radiator with push only fans at similar RPM. I took the temperatures during system idle, during a stress-test with Prime95 and during a stress-test with Prime95 and Valley Benchmark. By Powered by Invision Community. Started 40 minutes ago So should the cpu fan push into heatsink or pull away from heatsink. I have two Corsair AF120 Quiet Edition as intake fans in the front, one Corsair AF120 Quiet Edition in the rear and two Corsair AF140 Quiet Edition in the roof. There isn’t a large quantity scientific, detailed analysis on this subject out there, so I decided to try it out for myself. Introduction. The two CPU fans was spinning at 500 RPM on average. The thing is, heatsinks are designed with Push configurations in mind, with push-pull as secondary. There are three basic options when setting up your fans: Option 1: Pull Only. The CPU temperature rose to an average of 52°C. 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. Moving strictly on to two fans. 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. $7.29 $ 7. I presume. 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. TechChuan Started 1 minute ago Generally speaking, when a fan "pushes" ambient air into CPU, it creates more turbulence around sink's blades, which leads to better heat removal and smaller thermal resistance of the sink. Of course, all fans can still be installed in push or pull configuration. SSD: Samsung 860 EVO 500 GB. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt. CPU: I5-8600k 5.0ghz. The push/pull sickleflow was best since it had the highest cfm, but the push pull blademasters are also really good. The CPU fan span at an average of 900 RPM. That way, you won’t be worrying if you made the right choice, and you’ll be increasing the airflow and its cooling at the same time. Finally, the Prime95 and Valley Benchmark test. High pressure air flows to low pressure. Push, pull, or push/pull? Cooling, Featured Tech Reviews. Posted in Troubleshooting, By This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. This means the components are supplied with a high level of air. The CPU temperature rose to an average of, Moving strictly on to two fans. Started 17 minutes ago I also used an NZXT Grid+ V2 fan controller to lock all the system’s fans – CPU and chassis fans – to 50% speed, ensuring PWM control does not influence the testing today. The RAM are two sticks of HyperX Savage, running at 1866MHz with timings 9-10-11-27 with a total capacity of 16GB. Still, with the NF-F12 fans, very little noise. The CPU fan was still, on average, spinning at 900 RPM. juked 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. $9.99 $ 9. It’s the same thing, but in other words, I’m a bit lazy. 24°C is actually quite great for an air cooled idle temperature. 7:38. This case features three fans out-of-the-box, with two fans intaking at the front of the chassis. Less writing, more workshop! Follow these simple rules in life, and I promise you, things magically get easier. " LinusTechTips. Dominic Moass Maybe motherboard problem. 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. Pull is not generally designed for, and would actually not cool it as well as you would draw air more in from the sides of a heatsink more than pull air over the fins of the heatsink. I got the NH-U12S in black recently. The Prime95-test was run using the, When the Noctua NH-U12S was equipped with one Noctua NF-F12 fan, the temperature when idle was, When stress-testing the CPU with Prime95, the average CPU temperature was, Finally, the Prime95 and Valley Benchmark test. Sign up for a new account in our community. Posted in Servers and NAS, By Other tests by other people with different coolers didn't show any difference. It has compatibility for one or two NF-F12 fans, one of which comes as standard. Started 9 minutes ago On average, the CPU temperature was 47°C. 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. Treat others as you would like to be treated. #2. I will not go further than that, here and now. Push, pull, or push/pull? Here's an episode that we've been asked to do for quite some time. (Old, dead and replaced by The Toaster Project & 5.0). ivanom4 Quite impressive temperatures, for an overclocked and air cooled CPU. 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. The Prime95-test was run using the blend setting, to test our CPU and some of the RAM at the same time. They use the resources in the computer more dynamically. There isn’t a large quantity scientific, detailed analysis on this subject out there, so I decided to try it out for myself. Nothing spectacular. The 140 millimetre fans are PWM driven. The original LAN PC build log! RAM: 2x8 3333 mhz DDR4 Trident Z. MOBO: MSI Gaming Pro Carbon AC. When gathering the temperature information during these tests, I have taken an average of four values, tested and written down each five minutes. Posted in Troubleshooting, By Linus Media Group is not associated with these services. Plug the fan connector from the fan header. I asked myself the same question a while ago. To be tested. 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. The temperature remained the same during the entire experiment, but you should factor in a margin of error of +/- 1 degree Celsius. Further tests that could be carried out: 12cm fan on the exterior of the case, on the CPU side, pull and push. Here’s what I did: First, I built the system for testing in the Kolink Aviator V chassis. Hey new here! There is nothing "wrong" with being wrong. 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. Finally, the PSU in the system is an EVGA SuperNova G2 750W. Case: Cooler Master Masterbox Lite 5 RGB (modified) PSU: Seasonic Focus GX650 You’ll see there are two distinct groups – the Push/Pull radiators from 76% up, and the push only group from 40-50%. What you want is for the pull fan to increase flow.. not match it. 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. In terms of actual testing, I performed three tests per cooler – obviously testing out push, pull and push/pull fan configurations. 4.7 out of 5 stars 13. But I'm confused on how to plug it into my motherboard. 7:41. Forcing a Push-Pull scenario to an air-cooled CPU setup makes a difference.
