Introduction. Although, I would presume that it is a combination of the two, but mostly due to the ambient temperature in the case increasing. Again, I hope this graph below will make our lives slightly easier. Push Pull on CPU Heatsink - Does it Work? This means the components are supplied with a high level of air. All three 120 millimetre fans are driven through a Fractal Design standard 5 volts, 7 volts and 12 volts fan controller. Although, idle temperatures is nothing to brag with. Accordingly, I devised a simple test where the only changing variable was the number of fans used, or how they were mounted. Neither is this article written by a professional, which these in-depth guides about airflow are. More color variations in the product family. Posted in Cases and Mods, By I think then that this could work as a benchmark. There is nothing "wrong" with being wrong. Moving strictly on to two fans. Name- When the Noctua NH-U12S was equipped with one Noctua NF-F12 fan, the temperature when idle was 27°C. Nothing spectacular. Here's an episode that we've been asked to do for quite some time. TechChuan The temperature remained the same during the entire experiment, but you should factor in a margin of error of +/- 1 degree Celsius. Tags fan testing Hyper 212 LED Liquid freezer 240 push push/pull, XPG has given us a glimpse at the new hardware it intends to launch during …, © Copyright 2021, Kitguru.net All Rights Reserved, Fan config: Does it matter? December 28, 2016 Started 1 minute ago The CPU fan span at an average of 900 RPM. 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. Posted in Troubleshooting, By I got the NH-U12S in black recently. A massive Thank You for reading! 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. I took the temperatures during system idle, during a stress-test with Prime95 and during a stress-test with Prime95 and Valley Benchmark. Trying to get lower temperatures on idle is unnecessary, though. The average fan speed was the same as when only running with Prime95. But remember, the CPU is overclocked to 4200MHz. But I'm confused on how to plug it into my motherboard. Finally, the Prime95 and Valley Benchmark test. LinusTechTips. I took the temperatures during system idle, during a stress-test with Prime95 and during a stress-test with Prime95 and Valley Benchmark. 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. Still, with the NF-F12 fans, very little noise. Computer randomly freezes and all monitors go black, ethernet port locked at 10mb/s transfer speeds. 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. I asked myself the same question a while ago. 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. 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. Push-Pull on CPU Heatsink - Does it Work? 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! Of course, all fans can still be installed in push or pull configuration. Yes, the NF-F12 can be used in push/pull setups. High performance single fan CPU heat sinks almost always push air in rather than pull air out. 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. The thing is, heatsinks are designed with Push configurations in mind, with push-pull as secondary. "Here is some advice that might have gotten lost somewhere along the way in your life. $9.99 $ 9. The reason for this is that the actual CPU indirectly heats up. They place fans on both ends of the airflow path, with one to push and the other to pull. The two CPU fans was spinning at 500 RPM on average. TONS of people have asked me about fan configurations for radiators and heatsinks. The fan was, on average, spinning at 500 RPM. Ram is bugging? Started 8 minutes ago The CPU temperature rose to an average of 52°C. HDD: 1 TB 7200 RPM Seagate Baracudda, 1 TB 5400 RPM Samsung Spinpoint HD103SI. I've always seen fans mounted to push air down onto the heatsink fins, not pull it away. 7:41. The CPU temperature rose to an average of, Moving strictly on to two fans. It’s the air, and therefore the airflow in the case becoming warmer, due to the GPU emitting more heat, simply. pull cold air from the front push the warm/hot air out the back if possible. Harrison D Started 9 minutes ago 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. ivanom4 Upgrading PSU, do I need to replace the cables? When stress-testing the CPU with Prime95, the average CPU temperature was 50°C. Agreed there, it works the best for most cases! Which do I recommend? 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. Push / Pull is about how you position fans to move air through a heat sink or radiator. It has compatibility for one or two NF-F12 fans, one of which comes as standard. juked alfrederson 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? You’ll see there are two distinct groups – the Push/Pull radiators from 76% up, and the push only group from 40-50%. 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. 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. 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. I used the included F12 fans for the Liquid Freezer 240. 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. Started 17 minutes ago 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. Hey new here! Started 31 minutes ago 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. Learning from a mistake can be more valuable than not making one in the first place. Turn the push pins with a flat bladed screwdriver counterclockwise 90 degrees to release them. Reinsert the fan and find the push pins. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt. This time 1300RPM Push/Pull vs 1400RPM Push: The 140 millimetre fans are PWM driven. This all has to do with the defined rules of nature, with heat conduction and so on. 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. Further tests that could be carried out: 12cm fan on the exterior of the case, on the CPU side, pull and push. Maybe motherboard problem. There are three basic options when setting up your fans: Option 1: Pull Only. When running idle, the average CPU temperature was 24°C. 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.
