The direction a fan blows air is always determined by (A) the shape of the blades (sometimes called propellers) and (B) the direction they turn. Three cases with unique qualities were chosen for this test: the S340 Elite (relatively normal layout), the SilverStone Redline 06 (unusually high airflow), and the Corsair 600C (inverted motherboard). This question gets asked every year, it seems, and is worth a revisit: Where in the case should I put my liquid cooler? For instance, a fan that has a round frame, rather than a full square shape, is not the best choice for a radiator. This was with a 2-wire fan. That said, as long as there’s adequate cooling within the case (and the video card has a decent cooler), throttling shouldn’t really be a huge concern. The two configurations tested are more directly comparable than they were in the RL06, since the direction of airflow did not significantly change. Is the NZXT Kraken Compatible with AMD Threadripper. Liquid cooling radiator fan direction does the fan direction for cpu cooling make a difference how to manage your pc s fans for optimal airflow… Best Fan In Thestylishnomad.Com 13560+ Best Fan Thestylishnomad.Com 2019 When a PC gets hot, using fans is a simple and cheap way of … You will need to check what fan … You should also heed the placement of the fans. When looking at our fans, the Front or Intake side of the fan will always be the side that has the Cooler Master Logo in the center of the blades. Just remember that 3-pin fans can still work on 4-pin connectors – it just won’t be controllable. We continue our guides that show differences in radiator performance depending on the speed of the fans, thickness, and FPI of radiators etc. The funny thing is when I make my bottom fan as exhaust, the cpu temp suddenly reduce a bit during gaming.
This article was written by Steve Burke & Patrick Lathan from GamersNexus. When looking at our fans, the Front or Intake side of the fan will always be the side that has the Cooler Master Logo in the center of the blades. Also, there is a lesser gap between the adjacent blades of a static pressure fan. More and more fans today are designed to provide better air pressure whether they are going on a radiator or computer heatsink. In the S340, results were consistent between load and idle testing. Fans. In the very least, we can look at liquid cooler placement performance in a few different cases. Such a computer fan can push air with great force in one direction. If multiple options are present, and if “best” cooling is desired, consider front-mounted for the best CPU cooling or top/rear for the best overall balanced cooling. The radiator and fan combo itself can be mounted to the front or bottom for intake or the rear or top for exhaust, but it will be less efficient than a fan alone. More and more fans today are designed to provide better air pressure whether they are going on a radiator or computer heatsink. This article will just focus on the NZXT S340 Elite. How do most people have it? Those fans are designed to work only one way. TT RGB PLUS Software Control Fan M/B Sync Control Fan High Static Pressure Fans; Standard Fans / Accessory & Upgrade Kit ; Power Supply. be quiet! In the very least, we can look at liquid cooler placement performance in a few different cases. Bigger case fans are quieter than smaller ones. Ultimately, the answer is a big “it depends” – but we still tested it. The extra pin adds speed control to the fan, while 3-pins typically work as fast as they can. There were no anomalies in ambient temperature, CPU load, frequency, or voltage, but differences this small could be attributed to test variance, especially with the added complication of a pump speed curve. Those radiator fans are doing a lot of work. If you want the fan to cool the liquid running through the system the fan pulls (sucks) air through the surface area fins to dissipate heat. Thread starter devilchrist; Start date May 9, 2008; May 9, 2008 #1 D. devilchrist Weaksauce. You can make sure that the system isn't too loud, with the fan only spinning up faster when your PC gets warm. ... Mount the fans pushing in a direction … We hope to help you decide what kind of setup is right for you and to show the benefits of each. CPU temperatures were predictably lower when the radiator was placed in the path of unwarmed in-flowing air, while GPU temperatures were lower when inflowing air was not warmed by the CPU. For radiator testing, we simplify matters by eliminating the various air coolers designs – liquid coolers ultimately use parts that are easier to compare. Reversing the direction of rotation will be difficult. That said, let's take a look at where intake and exhaust fans can be positioned for ideal cooling (note that it's a simple matter of flipping a fan around to change its direction). We continue our guides that show differences in radiator performance depending on the speed of the fans, thickness, and FPI of radiators etc. We hope to help you decide what kind of setup is right for you and to show the benefits of each. This makes sense, since the front-mounted radiator is dumping heat onto the GPU. NZXT Kraken Guide: How to Optimize for Silence and Performance. For example, a 480mm radiator can hold four 120mm fans, while a 280mm radiator can have two 140mm fans attached. So while your results will vary depending on the fans, using a … The fan blades of high static pressure fans are more curved and are directed towards the heat source. The case alone has a huge impact on thermal performance, next dictated by the fans and coolers within the system, then the video card (how do its fans behave? Are bigger case fans better? This held true except for the top rear configuration under load, where dT was not only a degree lower than the front upper configuration, but also lower than the same test with the pump at full speed. Silent Wings 3 PWM. If possible, mount your radiator and fans as exhaust fans. Ultimately, we generally recommend trying to keep the GPU out of heat paths as most have a temperature ceiling of 82-85C prior to clock throttling – and GPU clock throttles are more noticeable in gaming performance. So my first experience of AIO coolers was the original H100 and whilst it was ok, it was never great, from day 1 i had problems with grinding from the pump and should have returned it but made do by using a fan controller to reduce the voltage which sorted the problem but more than likely led to the pump failing. be quiet! You will also be able to identify the Exhaust side as you will see power wires entering the fan motor. Radiator Fan direction, Suck or blow, in or out? For the final front-mounted configuration, the radiator had a gap between the 200mm fans, with no radiator fans mounted. Best 120mm / 140mm Static Pressure Fans for Radiators, Heatsinks and Restricted Spaces in PC Case. Joined Jan 13, 2008 Messages 74. Cooling performance is entirely a function of case fans and component fans. Please use our contact form for any further queries. 1. All fans will be configured to 100% in our testing. If you can get in there, you can probably reverse the direction by flipping two of the three sensors and two of the three windings. We sort of had to hack the solution together, seeing as our VRM heatsink and RAM wouldn’t allow a top-mounted radiator (X42) to clear. These high static pressure fans can deliver air at great force to the heat source and cools them down at a faster pace compared to standard fans. By changing the direction a fan is mounted, it can act as either an intake or exhaust.
Hooking them up in reverse will destroy the fan. You will also be able to identify the Exhaust side as you will see power wires entering the fan motor. ), the CPU cooler, all the way down to the power supply. Then side exhaust / rear intake. Asus Sabertooth x79 / 4930k @ 4500 @ 1.408v / Gigabyte WF 2080 RTX / Corsair VG 64GB @ 1866 & AX1600i & H115i Pro @ 2x Noctua NF-A14 / Carbide 330r Blackout Since the 120mm case fan is the most common size available in PC cooling, there are more fan options to choose from that will work with 120mm based radiators. How to determine the airflow direction of your case fans. If your PC is working just fine and you're happy with how loud its fans are, you don't need to adjust your CPU fan settings. Also, there is a lesser gap between the … When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise: . The main difference between placing the radiator at the front and top is that a radiator in the front could heat components inside the case and a radiator at the top could pull hot air from inside the case through the radiator which could heat up the CPU.
Airflow through the case is important, so yes, it matters. For some of the other cases we tested, we generally found that front-mounted radiators always raise GPU temperatures as the CPU heats up. Since you only supply power, there is a controller in the fan that senses rotor position and commutates the motor accordingly. An example of a typical cooling fan shroud, which directs air where it's meant to go. Putting them in an intake position will warm up the air via the radiator as it comes into your PC…which is basically defeating the purpose of water cooling your components in the first … Just mount it where it fits best. Also big mistake your top should be all exhaust fans,, and the CPU air cooler should be blowing same direction as the intake fans and out the exhaust fans on top and rear and what not. Likewise, if the blade is angled down and the fan turns the opposite direction, the reverse is true. Some cases would allow this more readily. 140mm 120mm 140mm high-speed 120mm high-speed. You will need to check what fan … Liquid cooling radiator fan direction does the fan direction for cpu cooling make a difference how to manage your pc s fans for optimal airflow… Best Fan In Thestylishnomad.Com 13560+ Best Fan Thestylishnomad.Com 2019 Fan Direction and Radiator mounting. I've tried switch over the fan orientation for side and rear. Today we address the subject of push, pull, push-pull fan setups and how they affect different radiators and performance. Edit: Also, no. Air flow or water flow? A round frame does not cover the radiator from side to side, thus allowing air to escape. The Rear or Exhaust side (the side that the air comes out of) of our fans will always be the side that houses the fan motor. A. For example, a 480mm radiator can hold four 120mm fans, while a 280mm radiator can have two 140mm fans attached. Without a shroud, pressure would be lost out to the sides as well. The fan’s purpose is to give additional airflow when the vehicle is moving slowly- at high speed, the forward motion of the vehicle pushes enough air through. PC radiators of this size offer a few advantages. This does not mean that the difference is significant, it just means that one number is lower. Controlling the CPU fan speed in your PC (or all the fans, in fact) is a way to give you more control over your Windows 10 experience. We have other cases tested in our article on GamersNexus, but the foundation is this: It depends on the case and the cooler. The primary component fans dwell on the CPU cooler (either a tower fan or radiator fans), the power supply, and the video card. Air should travel in clear path through the case. Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. Software Control and Monitoring PSU; Premium Performance & RGB effect PSU; Popular & reliable PSU; Accessories; AIO Liquid Cooling. This includes measuring how much a front radiator might reduce CPU temperatures at risk of raising GPU temperatures, or how a top-mount … Lastly, the fan airflow can be identified by the arrow markings on the fan housing. is a premium brand manufacturer of power supplies, cases and cooling solutions for your desktop PC. Compact cases, while lighter and more portable, might only have a spot for one fan. Some fans will use arrows/engravings to inform the user as to airflow paths. Both doesn't improve on my cpu temp during gaming. A. I know this from experience. Case testing is one of the least exact sciences, because it’s simply impossible to control for every possible variable. The Rear or Exhaust side (the side that the air comes out of) of our fans will always be the side that houses the fan motor. In the instance of our S340 Elite configuration, we couldn’t properly fit the radiator top-mounted (our RAM and VRM heatsinks didn’t allow clearance); realistically, that forces a front-mount, and so thermal differences really become irrelevant. This includes measuring how much a front radiator might reduce CPU temperatures at risk of raising GPU temperatures, or how a top-mount might do the opposite. The fan blades of high static pressure fans are more curved and are directed towards the heat source. Buy the best and latest pc radiator fan direction on banggood.com offer the quality pc radiator fan direction on sale with worldwide free shipping. For example, a radiator that supports 2 120mm fans is referred to as a 240 radiator (2 x 120), and a radiator that supports 3 120mm fans is referred to as a 360 radiator (3 x 120). For radiator testing, we simplify matters by eliminating the various air coolers designs – liquid coolers ultimately use parts that are easier to compare. Auxiliary cooling fans come with their own shrouds, which circle and surround the fan blades on all sides. For the Fans. Subscribe to RSS Feed; Mark Topic as New; Mark Topic as Read; Float this Topic for Current User; Bookmark; Subscribe; Mute; Printer Friendly Page; It has been a while since anyone has replied. The two configurations tested are more directly comparable than they were in the RL06, since the direction of airflow did not significantly change. Today we address the subject of push, pull, push-pull fan setups and how they affect different radiators and performance. I never see anyone recommend bottom fan as exhaust. CPU temperatures were predictably lower when the radiator was placed in the path of unwarmed in-flowing air, while GPU temperatures were lower when inflowing air was not warmed by the CPU. The radiator fan gets mounted to the radiator by using a screw that mounts through the entire fan (in one side, out the other). If you can't just flip the entire housing then this fan simply won't work in the other direction.\$\endgroup\$– JamesRyanMay 12 '16 at 16:22 3 \$\begingroup\$To open it, remove that black plug that's in the picture, and then use pliers to remove the c clip that holds the fan shaft in place. 1st side intake / rear exhaust. It should draw air through the radiator from front to back. If you want to heat an area the fan is set behind the radiator (or other heat source) and blows forward through the surface area fins to … There are several options for how a CPU cooler can exhaust heat from the CPU. Some big fans move the same amount of air as smaller fans at lower RPM (revolutions per minute). Corsair aio fan orientation custom corsair h60 processor liquid cooling corsair h60 processor liquid cooling h115i pro fan install direction the corsair a500 dual fan… The tiny electric motors within the fan do not need to spin fast. Reversing polarity for computer fans is not good for them at all. Top, front, or rear? With the pump set to “silent mode,” which establishes a pump speed based on the liquid temperature, CPU deltas should have been at least slightly higher with other temperatures less affected.
