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. Air flow or water flow? This was with a 2-wire fan. For radiator testing, we simplify matters by eliminating the various air coolers designs – liquid coolers ultimately use parts that are easier to compare. Ultimately, the answer is a big “it depends” – but we still tested it. Silent Wings 3 PWM. Since you only supply power, there is a controller in the fan that senses rotor position and commutates the motor accordingly. Also, there is a lesser gap between the … This article will just focus on the NZXT S340 Elite. We hope to help you decide what kind of setup is right for you and to show the benefits of each. Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. How many fans you can put in your PC is largely dictated by the case itself. It should draw air through the radiator from front to back. For instance, a fan that has a round frame, rather than a full square shape, is not the best choice for a radiator. 7,090 Posts #2 • Nov 15, 2009. 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. Top, front, or rear? The shroud also guides air where it’s supposed to go – through the radiator. I never see anyone recommend bottom fan as exhaust. 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. The two configurations tested are more directly comparable than they were in the RL06, since the direction of airflow did not significantly change. When a PC gets hot, using fans is a simple and cheap way of … 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. Without a shroud, pressure would be lost out to the sides as well. be quiet! Just remember that 3-pin fans can still work on 4-pin connectors – it just won’t be controllable. 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. Lastly, the fan airflow can be identified by the arrow markings on the fan housing. 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. Fan Direction and Radiator mounting. Both doesn't improve on my cpu temp during gaming. A note on charts: two configurations are compared in each chart, and the lower temperature between the two is highlighted green for each component. This makes sense, since the front-mounted radiator is dumping heat onto the GPU. 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. More and more fans today are designed to provide better air pressure whether they are going on a radiator or computer heatsink. 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). There are other features that are distinctive for a good radiator fan. Air should travel in clear path through the case. Some cases would allow this more readily. More and more fans today are designed to provide better air pressure whether they are going on a radiator or computer heatsink. This does not mean that the difference is significant, it just means that one number is lower. How do most people have it? be quiet! For some of the other cases we tested, we generally found that front-mounted radiators always raise GPU temperatures as the CPU heats up. 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. 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. Are bigger case fans better? I currently have my swifttech 220 radiator with Yate loom Mediums sucking behind the radiator in to the case. Is the NZXT Kraken Compatible with AMD Threadripper. 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. I know this from experience. The radiator fan gets mounted to the radiator by using a screw that mounts through the entire fan (in one side, out the other). You should also heed the placement of the fans. Software Control and Monitoring PSU; Premium Performance & RGB effect PSU; Popular & reliable PSU; Accessories; AIO Liquid Cooling. Some big fans move the same amount of air as smaller fans at lower RPM (revolutions per minute). Unique 6-pole fan motor for less vibration; High air pressure thanks to a frame with funnel-shaped inlets; Durable, high-quality fluid-dynamic bearing (up to 300,000 operating hours) Silent Wings 3. Q. 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. TT RGB PLUS Software Control Fan M/B Sync Control Fan High Static Pressure Fans; Standard Fans / Accessory & Upgrade Kit ; Power Supply. 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: . 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. 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. Edit: Also, no. So while your results will vary depending on the fans, using a … PC radiators of this size offer a few advantages. 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. For the final front-mounted configuration, the radiator had a gap between the 200mm fans, with no radiator fans mounted.
