Overclocking Why do my GPU fans need a push start? I tryed what he did and it seems to work on my G75 VW as well. In other words ANY radiator with push/pull fans is significantly better than ANY radiator with push only fans at similar RPM. 1 fan pushes air into the heatsink. The key is to find the correct ratio between the 'push' and 'pull' fans. When the CPU fans kicks in, it feels like it's pushing air out? Push-pull fan configuration will allow you to get even better thermals and make sure you squeeze some more MHz out of your hardware. First of all they have long warranties, typically 8 years, and you don’t want to upgrade to a more powerful CPU or GPU … Push / Pull is about how you position fans to move air through a heat sink or radiator. It's just that one is pushing air into the heatsink, and the other is pulling air out of the heatsink. You should push if you can, if you have to choose one. As a direct comparison, if you were to add a (matching) fan to a given AIO, they could develop greater static pressure working together. If you have 3 intake fans, plan for 3 exhaust fans. Lets make it more specific, instead of thinking of the effect of other fans on the system, lets consider a radiator outside of the case with 2 fans pushing air through the fins or 4 fans in push pull configuration. Is that right? Lots of people like push but as much hate as Ill get pull has its advantages. Hi all, I previously posted that my GPU fan isn't working and after searching the Net i found numerous people with the same issue. Cooling, Featured Tech Reviews. Just food for thought. This way we can assess whether fan configuration makes much difference whether you are using a radiator or a more typical heatsink tower. Your fan should be big enough to move the volume of your area 2 to 3 times every minute. That means a 70CFM fan will move 70 cubic feet of air in one minute. That's a whole lot of the radiator (or heatsink for air cooling) that's not getting any air over it. On a rad you can get most by blowing air through it while fans like to cake on the blades and it can be hard to get in each nook lol. ? However, if you go for an AIO, you can certainly get away with 2 intake fans. I used the included F12 fans for the Liquid Freezer 240. Clearly in this case no external influences would apply (except ambient temps of course). Kimbie, you can run an H100i in push or pull fashion within the Air240 case. Exhausting air form inside the case through a radiator may give you a few degrees higher CPU temp in games because GPU makes a lot of hot air. When I built my first PC a few years back, I used the excellent Cooler Master Hyper 212 EVO to cool the processor. I bought more Corsair "quiet" PWM fans when I saw the 2-pack at Fry's. Dec 6, 2005 #36 M. Marci Limp Gawd. 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. But as said it depends on the fans and the radiators. The cable coming from the fan header has two in-line 4-pin connectors. Learn about GPU fan size, connector type, mounting points, and fan design. Tips on how to find out the right replacement fan for your graphics card model. Accordingly, I devised a simple test where the only changing variable was the number of fans used, or how they were mounted. I am contemplating using a push/pull configuration now on my RX360 rad. To get accurate data from comparing various fan configurations, it was very important I devised a scientific and easily repeatable test. Read on for how I put this to the test, as well as the all-important results and what conclusions can be drawn from the data we gathered. The two included 3-pin fans are probably higher SPI than typical 120mm fans, so I assume they would need to be left as the "push" fans. Generally the push fans are high static pressure (usually 3-pin DC). But why would I have to physically push the GPU fan to start spinning? Dominic Moass They place fans on both ends of the airflow path, with one to push and the other to pull. My gpu has gone up 3 C to 71 which is nothing, I can just increase the fan speed if need be. Link to post Share on other sites. I'm trying to decide if I should push/pull my AIO radiators or not. These fans take in the hot air from the inside of your PC case. Let’s double check that at medium fan speeds. In terms of actual testing, I performed three tests per cooler – obviously testing out push, pull and push/pull fan configurations. Generally the push fans are high static pressure (usually 3-pin DC). 9 years ago Dominic Moass This article is designed to cut through the noise and get to the facts: does it actually matter where you mount your fans, or how many you use? There was 1 guy who posted that his GPU Fan starts to spin after physically pushing it after a Restart or cold start.

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 was wondering which way would be better for the fans since the whole enclosure is external. The greater the CFM, the more air a fan moves. If you plan to run fans in the top, it will be a tight squeeze, and the front most fan will rub the coolant lines. PSU: DO NOT cheap out on your PSU. Another thing we’d like to note, not related to the push-pull configurations is that Vardar fans do slightly better in pull configurations. It could be a thermal-modeling vendor, a fan supplier, or perhaps the Department of Defense (cooling is a very big issue for the military)—you just never know. Several fans have dead zones in the center that are fairly large in push configuration. The Kukri fans even have an RPM advantage here. *laughs* I mean, yeah, you’ll have better cooling with push-pull than with just push or pull. ie. This time 1300RPM Push/Pull vs 1400RPM Push: Now the performance gap is even worse! When ever I turn the power on the fans just wobble a bit and need me to push them a little for them to start spinning. Most GPU coolers blow air to the GPU, but there are some reference coolers that push air out the case. In Eurpose, metric fans are rated in m3/hr - cubic metres per hour (m3/hr). 30-40% on Push vs 85%+ on Push/Pull. Step 5: Depending on the graphics card length, you can also run a push-pull setup like I do for my personal system at home. Using radiator as intake on the other hand hardly effects GPU temps in game. I might switch the fans around when I get it to see if affects the temps at all. A blower GPU design covers these fins with plastic. And it would kind of defeat the purpose if the 2 fans contradict one another. I believe the gelids are 1000 rpm and the stock kit fans are 1700 rpm. What do I need to know? CPU fan pushing air … Push + pull should increase airflow, but keep dead zones in mind. With this we conclude the push-pull testing, and we hope that we’ve helped you choose what kind of fan configuration is right for … Every fan features a cubic feet per minute (CFM) rating, which measures of the volume of air it moves in a minute. The key is to find the correct ratio between the 'push' and 'pull' fans. Most of which is that its easier to clean out dust from the rad than a fan. pull would be easier to clean but I feel push would be more efficient. 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. Do you guys use any special kind of fans for that, does it need to be at a certain speed to be able to pull through the filter? Thanks. On the oppoiste side a fan sucks the air out. So you can run the fans slower for the same cooling. 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. Currently, I got only the gelid as push configuration. Hi, I tried to search this forum and Google so hopefully this isn't a duplicate thread.I would like to run 4 fans in push/pull as exhaust on my 3090 XC3 Hybrid and allow the GPU to control all 4 fans. Here’s what I did: First, I built the system for testing in the Kolink Aviator V chassis. Joined Fans are rated in either cubic feet (CFM) or cubic meters per minute in North America. ... 15 C lower on the Aida 64 fpu test and 11 C while gaming. 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.
