fans on inside or outside of radiator

IMHO one advantage of water cooling is that you can bring the heat outside the case. The top exhaust fan you show just removes some of the air from the radiator. This fan has ultra-tight tip clearance of 0.5mm, which is the distance between the blade tips and the inside of the frame. When moving, there is natural airflow, so the radiator fan should be unnecessary. Make sure the screw holes are all aligned between the fans and the radiator while rasing them to the bracket. I have a 2015 Chevy Cruze LT with 45,000 miles on it. The 2 fans inside radiator work fine. 4 comments. The fan generates a high static pressure of 2.34mm H2O and Airflow of 60 CFM. Instead it will create turbulence inside the shroud, spinning the air, but not efficiently pulling it through. Both axial and sometimes centrifugal (blower/squirrel-cage) fans are used in computers. Nepton 280L radiator is too large for the cut out at the top of the case and will not install from outside of the chassis. The radiator transfers the heat from the fluid inside to the air outside, thereby cooling the fluid, which in turn cools the engine. The radiator fan is positioned between the radiator and the engine, and is in charge of cooling the car. We continue our guides that show differences in radiator performance depending on the speed of the fans, thickness, and FPI of radiators etc. 5. Radiator fan running high speed Radiator fan running high speed Secure the fan-cooler to the bracket. Its been working pretty good, but Ive noticed that the water temp drops quite a bit when the side panel is off, mybe indicating that the way its currently set up, the radiator fans might suck some warm air from the inside of the case over the rad. Only Time Will Tell has All Kinds of 12Cm Cooling Fan Aperture Inside and Outside Light Pink LED Silent High Wind Volume Computer RGB Cooling Fan,Double Copper Tube CPU Radiator 12cm Large Fan Air-cooled Hydraulic Bearing Glare Four-color I5 Double Heat Pipe Copper,12cm Chassis Fan Eclipse Dual Aperture Silent RGB Fan LED Symphony Cooling Chassis Fan and more On Sale, Find the Best China … If the front brings in more air than the Radiator exhausts (which should be possible to do silently with the 200 mm fans), the excess air will flow towards the back of the case and will exhaust through the holes by the PCI cards. I would like to mount my electric fan in front of the radiator and have it blow outside air into the engine comparment. Reply. First, which is better; Pusher-style fans or puller fans? We hope to help you decide what kind of setup is right for you and to show the benefits of each. Autumn_ May 16, 2019 @ 11:28pm So you have a top mounted AIO, and you want to know if you can flip the fans to exhaust? The side of the radiator where the tubes connect should be at the bottom, and the pump should be mounted in a position where it is slightly lower than the top of the radiator, where air is captured. If the fan is too far inside of the shroud, it won’t pull as much air through the shroud as it could. Today we address the subject of push, pull, push-pull fan setups and how they affect different radiators and performance. Some fans will use arrows/engravings to inform the user as to airflow paths. To answer this, it seems like the consensus is in favor of the pull style fans. The radiator fan on my 2018 10th gen sport comes on whenever the interior fan is on, the only time it doesn't is when I manually switch off the air con option on the climate control screen, even if the outside temperature is 5 deg and the inside temp is set to 25 so only hot air is requred the rad fan comes on, is this the normal way the radiator fan works. Yeah, that's perfectly fine. However, by doing this you are also blowing hot radiator air into your case, thus higher enclosure temp. I want to know if it is okay to have the fans push inside air out. Many ignore Corsair's advice, and stick to the conventional orientation. Or should i sandwich the rad between the 2 fans outside the case. if so which is the best way for the fans to face? These cooling radiator fans are especially helpful when your car is moving too slow to obtain external airflow, or when you are stationary, and air can't move through the grille. This seems to be the same thing as 1 on the inside sucking outside air in. How do most people have it? Any help would be appreciated. Thread starter devilchrist; Start date May 9, 2008; May 9, 2008 #1 D. devilchrist Weaksauce . This in turn cools the antifreeze and water that's within the radiator, which keeps the vehicle's engine cool as well. It’s made up of a 1/2-inch thick formed-aluminum shroud and one or multiple electric thin-line fans. You can put the fan isolator inside the room so long as it is outside zone 2. Having overheating problems in the day when it is hotest. I would assume the difference is that if they are underneath the radiator then it will pull air from the case up and out the top, whereas if they are mounted on top of the radiator then it will pull cool air into it. Reply. You want the coolest air blowing across the radiator, which in most cases is the outside ambient air, not the case air Tops fans blowing out Front, side, bottom intake . #2. If the blades are not far enough inside the shroud, the fan will pull air from around the shroud rather than through it. 1. For the past couple months, since February, my radiator fan in my car has been coming on frequently- when I am sitting in my car still or when I’m driving in very slow traffic.. it comes on for maybe 3-5 seconds and then stops, and comes back on in maybe 15-20 seconds and then repeats. Corsair advise this because by configuring the radiator fans as intake, you are passing cool outside air over the radiator, thus lower CPU temp. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. Puller fans provide more cooling capacity than pusher fans. Joined Jan 13, 2008 Messages 74. So fans blowing enclosure air through the rad and outside. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit. Holding paper in front of a powered fan will also reveal airflow. As for radiator fans, those generally use longer screws. Dec 6, 2010 #5 Remember it will come under part P.....you will need to register it to comply with the law.....although I doubt you will be hung,drawn and quartered if you dont. Engine light on - fan 2 circuit code. Or should I keep the case fans inside under the rad and the fans in the kit above the rad. The PWM fan comes with Noctua’s SSO2 bearing and spins at speed of 450 – 2000 RPM. Radiators are also often used to cool automatic transmission fluids, air conditioner refrigerant, intake air, and sometimes to cool motor oil or power steering fluid. 3. Radiator mounted at the front with the tube side at the bottom One good mounting position is to mount the radiator of the cooler at the frontal area of the case interior. An electric fan is preferred because when you need a fan the most (at idle or cruising speeds) an electric fan is delivering maximum air independent of engine RPMs. Place the 2 140mm fans on top of the radiator and raise them from inside the case to the liquid cooler bracket. I want to mount my radiator outside the case on top of it. Can I put the fans on the outside so they're visible? Radiator Fan direction, Suck or blow, in or out? It pulls air through the radiator and has less impact on airflow at high speeds than a pusher fan since it is behind the radiator. This is my first time building so I’m sorry if this is a really stupid question. A computer fan is any fan inside, or attached to, a computer case used for active cooling.Fans are used to draw cooler air into the case from the outside, expel warm air from inside and move air across a heat sink to cool a particular component. Me I would have the radiator/fan for the liquid on the back and blow in. D. Deleted member 9648 . One thing I did differently to the other tests I have seen is not locking any fan speeds in the system, so the GPU/Radiator/case fans were set to the default quiet curves. Function. This prevents back pressure and provides constant static pressure to the heatsink and radiator fins. Should I put the 2 fans inside the case under the radiator or above the radiator outside the case. E. ezzzekiel. When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top. S. sjm. This fan usually comes on when temp is at the highest. I just bought RGB fans and if the fans are on the inside of the radiator it defeats the purpose of them kind of and cant see the lighting. 4. Dec 6, 2010 #4 if there is a window then you dont need an isolator . Ive been running it like this for a few months now, the fans suck cool air in from the outside of the case. The radiator fan gets mounted to the radiator by using a screw that mounts through the entire fan (in one side, out the other). Operating the fan is a decision with many variables, and in a well-designed system it happens when hot outside and not moving, and perhaps after a delay (the radiator doesn't get hot immediately). I Have same NZXT h500i case and Kraken x62 cooler. Question. Pulling cool air from outside and passing through the rad into the case and then out the exhaust in the back. (So it would be inside of case, fans, radiator, outside of case.) Basically, I have both fans and radiator inside chassi sucking the air from inside. I'm getting a new system in a week or so and I will retain the AIO, but after reading this thread I'm going to change to a push configuration with the fans still mounted on the outside of the case. I currently have my swifttech 220 radiator with Yate loom Mediums sucking behind the radiator in to the case. Fans that move 2000-2300 CFM's are worth the investment. Mounted on the engine side of the radiator, a pull fan does not interfere with airflow at highway speeds. Preference should be given to a "pull" vs. a "push" fan. Third fan on the outside of radiator doesn't come on. Manufacturer recommends the fans on the radiator pull outside air in. Tabs on the side of the shroud attach to the flanges on the radiator side plates with sheet metal screws. share. If they are being used as an intake, is it the case that exhaust fans don;t necessarily need to be at the top and can be just at the rear of the case? Fan manufacturers have continued to reduce the thickness of the fans and now there is a shroud from Cool Craft that when combined with the fan only measures 2-5/8-inches thick. Independent tests have shown that even with a pusher style fan mounted only 5/8 of an inch away from the face of the radiator, there is still a vast amount of air that escapes from around the skirt between the radiator and the fan blades. Reply. save. HAF-X (Blue fans) i7-2600K 3.40 Thermaltake Frio 12xBR+24xDVD 120g Intel SSD 500g HDDx2 16g Crucial Tracer LED Ram AMD Radeon 7950x2 GA- … A puller fan on the other hand sits right behind the radiator. A radiator fan uses its fast spinning blades to draw in outside air. This leaves me a bit confused on whether they are being treated as intakes (cool air from outside, pumping warm-ish air back in the case until it gets exhausted elsewhere) or exhaust points for the case. What would be the optimal setup.
