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! 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. Powered by Invision Community. Neither is this article written by a professional, which these in-depth guides about airflow are. Started 31 minutes ago Started 40 minutes ago Computer randomly freezes and all monitors go black, ethernet port locked at 10mb/s transfer speeds. 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. It’s the same thing, but in other words, I’m a bit lazy. 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. 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. 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.. Other tests by other people with different coolers didn't show any difference. Maybe motherboard problem. Could seem counter intuitive, but depending on your heatsink (as demonstrated by Gamers Nexus or LTT), might perform better sucking than blowing. The push/pull sickleflow was best since it had the highest cfm, but the push pull blademasters are also really good. Sign up for a new account in our community. Temperatures were 70.7C at load, not the coolest but nothing to worry about. But I'm confused on how to plug it into my motherboard. Seeing this, if the fans are taken into manual control, we might be able to take some more degrees of that value. Ram is bugging? 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. 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. Fatty ivanom4 Linus Media Group is not associated with these services. Still, with the NF-F12 fans, very little noise. Started 20 minutes ago Posted in Storage Devices, Linus Media Group Very little of this is necessary to know in order to understand this small experiment. Case: Cooler Master Masterbox Lite 5 RGB (modified) PSU: Seasonic Focus GX650 A template to show if it makes any significant difference. But remember, the CPU is overclocked to 4200MHz. By When stress-testing the CPU with Prime95, the average CPU temperature was 50°C. SSD: Samsung 860 EVO 500 GB. They use the resources in the computer more dynamically. Forcing a Push-Pull scenario to an air-cooled CPU setup makes a difference. 24°C is actually quite great for an air cooled idle temperature. 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. Plug the fan connector from the fan header. Dominic Moass That’s quite personal to decide. A massive Thank You for reading! The CPU fan span at an average of 900 RPM. For the Hyper 212 LED, I used CoolerMaster’s Air Balance 120mm fans for this test. 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. There isn’t a large quantity scientific, detailed analysis on this subject out there, so I decided to try it out for myself. Magic&shell Heatsink CPU Pin 12PCS Mounting Plastic Pins Push Screw for Intel LGA Socket 775 CPU Cooler Heat Sink Fans. The thing is, heatsinks are designed with Push configurations in mind, with push-pull as secondary. These values has been tested in a few different circumstances. The CPU fan was still, on average, spinning at 900 RPM. When gathering the temperature information during these tests, I have taken an average of four values, tested and written down each five minutes. Reinsert the fan and find the push pins. Name- 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. Started 8 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. TONS of people have asked me about fan configurations for radiators and heatsinks. Find out what fan configuration is best for cooling down your radiator. well thanks for the read i guess. #2. LinusTechTips. This system has a presumed negative pressure. However, the H60 allows me to use SL120s in push/pull configuration. Push, pull, or push/pull? I asked myself the same question a while ago. The CPU is overclocked to 4200MHz, and all of the tests are executed with 4200MHz on the CPU cores. 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. 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. Push-Pull on CPU Heatsink - Does it Work? Nothing spectacular. Started 17 minutes ago 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. BardiaMGTGC 7:41. 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 hope. When running idle, the average CPU temperature was 24°C. Push Pull on CPU Heatsink - Does it Work? The results might vary in other systems than mine. And air should push down over your GPU and CPU from their own fans, and will push out the sides of those fins naturally. Posted in Troubleshooting, By Although, idle temperatures is nothing to brag with. This is fairly normal air-cooled CPU temperature when running idle. To be tested. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. This time 1300RPM Push/Pull vs 1400RPM Push: They place fans on both ends of the airflow path, with one to push and the other to pull. Trying to get lower temperatures on idle is unnecessary, though. Press the push pins in the order shown to secure them. Turn the push pins clockwise 90 degrees to reset them. Posted in Phones and Tablets, By 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. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt. Posted in Troubleshooting, By Hey new here! 7:38. 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. CPU compartment: No extra fan. All three 120 millimetre fans are driven through a Fractal Design standard 5 volts, 7 volts and 12 volts fan controller. #3.
