There's no easy answer when it comes to deciding whether 120 or 140 mm fans are better. It ultimately comes down to personal preference and what you're looking for in a fan. That said, there are some advantages and disadvantages to both sizes that you should keep in mind. 120 mm fans are typically cheaper and more widely available than their 140 mm counterparts. They're also easier to install, since they fit into more cases. However, they move less air than 140 mm fans and can be louder. 140 mm fans, on the other hand, are quieter and more efficient
There is no definitive answer when it comes to the question of whether 3 or 4 blade fans are better. Each type of fan has its own advantages and disadvantages that should be considered before making a purchase. 3 blade fans are typically more affordable than their 4 blade counterparts and are easier to find in stores. They also tend to be less noisy and have a simpler design. However, 3 blade fans can produce more vibration than 4 blade fans and may not move as much air. 4 blade fans are often more expensive than 3 blade fans, but they can move more air and produce
There's a lot of debate over which type of fan blade is better: curved or straight. Curved blades are designed to create less turbulence and move more air, while straight blades are more efficient at moving air over a longer distance. So, which is better? It depends on your needs. If you're looking for a fan that will move a lot of air quickly, then a curved blade is the way to go. If you need a fan that will move air over a longer distance, then a straight blade is your best bet.
There are many reasons to like the Flex fan over the Clutchfan. The Flex fan is more powerful, efficient, and quieter. It also has a much more stylish design. The Clutchfan is not as powerful, efficient, or quiet. It also doesn't have a very stylish design.

This SPAL "low profile" fan competes with only a few others in this particular 5.2" (blade) diameter and price range, but I believe THIS fan is significantly better than those. First off, for its small size, it is most likely the thinnest and most performing fan available. It appears to be well-designed, and the production method used by this Italian company shows a high level of quality control. When I double-checked the specifications, I discovered that they were rather correct in terms of the mechanical dimensions and the current rating of this fan's electric motor. A motorcycle oil cooler is what I'm using, and there is hardly any clearance behind the cooler—barely enough for any fan. The physical dimensions of the fan had to not exceed those actually provided by SPAL because there are impediments on both sides, including hot exhaust pipes, and right behind the cooler. Although I lack the equipment to measure it, the fan's specified air flow rate of 342 CFM (at zero static pressure) seems correct based on my empirical tests. Although the OEM doesn't define it, I found that the fans rotate at about 5840 RPM.It is about a 62W fan because the minimum current specification is 4.8A at 13.0Vdc, at zero static pressure. My motorcycle battery's 12V demand at nominal voltage was 4.35A. (not under charge).The absence of a finger guard is the only drawback that comes to mind. It is undoubtedly strong enough to sever a finger, but installing a protection would reduce the effective flow rate at the expense of a fan that runs more safely. Be aware that there is an identical version with a guard, but Amazon does not appear to sell it. The fact that this fan is made of plastic rather than metal is the only other possible drawback, but it is nevertheless described as waterproof to make up for any loss of overall rigidity and longevity.I am a satisfied client because this fan will function well overall in my application and won't need any fitting modifications.

So that I wouldn't have to waste time installing them, I bench tested both fans. I'm glad I did since one of the fans was already dead when I got there. chose to exchange for a different unit. Two of the second unit's fans are operational. I won't learn how well the fans function until next summer because it's still early and the temperature isn't too high. While the hood is up, the motor temperature does decrease when both fans are operating. Temperatures begin to climb again as soon as I close the hood. To test whether this system will keep the mild built 450HP SBC cool, I have to drive the sled through heavy traffic. It was not kept cold enough by a single 16-inch fan housed in a shroud made especially for my radiator.Was by no means a direct match, but with a few custom modifications and adjustments to the flanges, there are enough pieces in the package to place it on an aftermarket 25x17 aluminum radiator with side mounting flanges. You just receive the mounting gear and the fans enclosed in a shroud. There are no connectors on the wires. This minimalist kit looks nice. Although I don't like them, the decals on the motor covers aren't too loud. When contrasted to SPAL fans, who scream like banshees, the fans are not as loud. I'll be satisfied and think it was money well spent if this low profile dual fan system keeps my motor temperatures from rising above 210 while I'm stalled in traffic.

performs better than anticipated. I need more air to circulate through the radiator and around the engine since I now have or previously had vapor locking issues. Compared to the OEM fan, this fan pushes or pulls a lot more air. You can't beat it for $30. From the front of the car, I can feel air moving through the radiator. Therefore, it is flawless for me. I also purchased the extension, which is almost half as long as the OEM extension and so still fits. However, it is now much closer to the radiator; if it were much further away, I would have to remove the radiator in order to install the fan, which is something I don't want to do.

It was purchased for my CJ7. I replaced it with a 4.0HO because I didn't like the mechanical/electric fan arrangement. On my previous CJ7 with a V8, I installed a Flexalite 160, and I really enjoyed it. This fan was also effective. It fit beneath the stock radiator almost perfectly, and the control module functions well. There are many options available, however I had to change the brackets they gave because they came in two distinct types. Heavy duty 10 gauge wiring and all hardware were included. There was nothing else I required. It maintains my engine at 190 degrees Fahrenheit, and I can modify it for wheeling, winter and summer weather. Additionally, the engine revs up better thanks to the HP I gained from fully removing the mechanical fan.

I fitted AC to my 1965 Ford Mustang standard 289 but didn't care for the fan, clutch, or shroud comb. I desired electricity. There wasn't much room between me and the new America Eagle 2 1 "this fan, the water pump, and the core radiator. A I mounted it with 1/4-20 carriage bolts and added 4 aluminum brackets because I don't like the thru-the-core idea. When I turn on the AC, the hi-speed fan turns on and keeps my car at 185 all day; I haven't seen 200.For a smooth seal, I also added some rubber from Amazon.

When running, the fan does a good job of cooling the engine. While idling, much quicker than the stock fan clutch. Although the outside of the car is a little noisy, I rarely hear anything inside. When fitted with the gasket on the front of it, it also vibrates very little. The mounting straps for my fan are included and cost a little bit of money on this website. It was never mentioned that the straps were there in the description. That was the only problem I had thus far. Overall, if you need something discrete, this is a fantastic purchase.
High velocity fans are definitely worth it! They move a lot of air and can make a big difference in your home’s comfort level. They’re also great for circulating air in a room and can help reduce energy costs.
Are higher rpm fans better? Higher rpm fans can spin faster and move more air than lower rpm fans. This can be beneficial if you need to move a lot of air through your case, such as when overclocking your CPU. Higher rpm fans can also be louder than lower rpm fans.
Plastic or metal fans better? This is a question that does not have a definitive answer as it depends on the person's preferences. Some people might prefer plastic fans because they are usually cheaper than metal fans. Plastic fans are also often lighter in weight, making them easier to carry around. On the other hand, some people might prefer metal fans because they tend to be more durable and have a longer lifespan. Metal fans also have the ability to create a stronger airflow than plastic fans. Ultimately, the decision of which type of fan is better is up to the individual.
Engines typically run better with colder air, since the air is more dense and thus can better fill up the cylinders. However, if the engine is too cold, it may not start properly or may not run as smoothly.
No, adding more fans will not increase CFM. CFM, or cubic feet per minute, is a measure of the volume of air that a fan can move in a minute. The number of fans has no effect on the CFM.
No, higher CFM does not necessarily mean better cooling. In fact, sometimes higher CFM can actually lead to less effective cooling because it can cause the air to circulate too quickly and not stay in contact with the components long enough to properly cool them. The best way to determine the optimal CFM for your particular setup is to experiment and see what works best.
