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. Reinsert the fan and find the push pins. Started 8 minutes ago I asked myself the same question a while ago. Further tests that could be carried out: 12cm fan on the exterior of the case, on the CPU side, pull and push. When stress-testing the CPU with Prime95, the average CPU temperature was 50°C. To be tested. Here's an episode that we've been asked to do for quite some time. A template to show if it makes any significant difference. Started 17 minutes ago Name- Testing push vs pull vs push/pull, XPG previews new cases, RAM, SSDs, coolers and a gaming ultrabook for CES 2021. #1. Harrison D Though, my averages are not as in-depth as those. satellite999 Linus Media Group is not associated with these services. December 28, 2016 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 know typically we look at GPU thermals here but, the CPU has to "feed" the GPU or it's the bottleneck. High pressure air flows to low pressure. You’ll see there are two distinct groups – the Push/Pull radiators from 76% up, and the push only group from 40-50%. This will create an accurate value which we can use as our platform when experimenting with this setup. Mack Shaun. 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. Powered by Invision Community. Could seem counter intuitive, but depending on your heatsink (as demonstrated by Gamers Nexus or LTT), might perform better sucking than blowing. The temperature remained the same during the entire experiment, but you should factor in a margin of error of +/- 1 degree Celsius. The case is a Fractal Design Arc R2 Mini, with a custom built panel for the drives to make sure no airflow from the intake fans is obscured. 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. The thing is, heatsinks are designed with Push configurations in mind, with push-pull as secondary. 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. Not strange, since it's a GPU benchmarking program. 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? When running idle, the average CPU temperature was 24°C. 7:41. 7:38. 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 results might vary in other systems than mine. Quite impressive temperatures, for an overclocked and air cooled CPU. Started 1 minute ago Dominic Moass 99. So should the cpu fan push into heatsink or pull away from heatsink. 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. These tests are carried out in a “best possible” scenario, with only the benchmarking and monitoring software running. Ram is bugging? The GPU is an Nvidia GeForce GTX 760OC from ASUS. What you want is for the pull fan to increase flow.. not match it. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. Posted in CPUs, Motherboards, and Memory, By Accordingly, I devised a simple test where the only changing variable was the number of fans used, or how they were mounted. Cyberpunk 2077). I presume. It’s a marginal difference. Excellent job, Noctua! 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. 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. pull cold air from the front push the warm/hot air out the back if possible. Posted in Troubleshooting, 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 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. 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. The push/pull sickleflow was best since it had the highest cfm, but the push pull blademasters are also really good. #2. To get accurate data from comparing various fan configurations, it was very important I devised a scientific and easily repeatable test. Push Pull on CPU Heatsink - Does it Work? That’s quite personal to decide. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt. Now, the final test with Prime95 and Valley Benchmark. Less writing, more workshop! 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. This case features three fans out-of-the-box, with two fans intaking at the front of the chassis. Which do I recommend? 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. Finally, the Prime95 and Valley Benchmark test. LinusTechTips. Push-Pull on CPU Heatsink - Does it Work? 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. Started 31 minutes ago The two CPU fans was spinning at 500 RPM on average. In my testing system, I’m using a Noctua NH-U12S CPU cooler. $9.99 $ 9. They use the resources in the computer more dynamically. Which do I recommend? Started 20 minutes ago 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.. 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. Though, the difference between only one fan and having two fans is small. Posted in Cases and Mods, By I used the included F12 fans for the Liquid Freezer 240. 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? When stress testing with Prime95, the average temperature on the CPU was 45°C. Of course, all fans can still be installed in push or pull configuration. Case: Cooler Master Masterbox Lite 5 RGB (modified) PSU: Seasonic Focus GX650 Started 18 minutes ago Posted in Troubleshooting, By Moving strictly on to two fans. Very little of this is necessary to know in order to understand this small experiment. 4.7 out of 5 stars 13. 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. I have a Xigmatek hdt-s963 92mm heatsink/fan on my cpu right now. Forcing a Push-Pull scenario to an air-cooled CPU setup makes a difference. TechChuan 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. But I'm confused on how to plug it into my motherboard. Temperatures were 70.7C at load, not the coolest but nothing to worry about. More color variations in the product family. Yes, the NF-F12 can be used in push/pull setups. 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! These values has been tested in a few different circumstances. These fans are designed for heatsinks and radiators specifically. Posted in Phones and Tablets, By #3. - MageTank 31-10-2016, You need to be a member in order to leave a comment. There isn’t a large quantity scientific, detailed analysis on this subject out there, so I decided to try it out for myself. 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. Agreed there, it works the best for most cases! A massive Thank You for reading! GeForce GTX 560 Ti Twin Frozr II vs Reference Heatsink Cooler Linus Tech Tips. 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. alfrederson 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. Started 9 minutes ago The RAM are two sticks of HyperX Savage, running at 1866MHz with timings 9-10-11-27 with a total capacity of 16GB. 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. Magic&shell Heatsink CPU Pin 12PCS Mounting Plastic Pins Push Screw for Intel LGA Socket 775 CPU Cooler Heat Sink Fans. Hey new here! Push, pull, or push/pull? Here’s what I did: First, I built the system for testing in the Kolink Aviator V chassis. The 140 millimetre fans are PWM driven. Started 40 minutes ago Upgrading PSU, do I need to replace the cables? When gathering the temperature information during these tests, I have taken an average of four values, tested and written down each five minutes. 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. 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'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. Let’s double check that at medium fan speeds. The CPU temperature rose to an average of 52°C. This all has to do with the defined rules of nature, with heat conduction and so on. Average fan speed was the same as when only running with Prime95 and Valley Benchmark ; and appear to stupid. Strange, since it 's best to keep your mouth shut ; and appear to push/pull! The chassis time 1300RPM push/pull vs 1400RPM push: of course, all fans still. Pull vs push/pull, XPG previews new cases, RAM, SSDs, coolers and a Gaming ultrabook for 2021.
