How much rpm is good for table fan?
Features and Benefits of Pedestal Fans – Crompton Greaves Consumer Electricals Limited are gaining popularity all across the country. Their efficient performance and instant cooling make them an ideal choice for households all across India. These fast-oscillating, can cool down any space in your home.
Here are some things to keep in mind before buying a pedestal fan! Air delivery Pedestal fans are known for their powerful air delivery which is measured in CMM or Cubic Metre Per Minute. This basically stands for the volume of air pushed out per minute. The more air that the fan pushes out, the stronger the breeze will be.
CMM is also dependent on the space of your choice. For example, a Farrata pedestal fan is used in large spaces and can cover 3,000 CMM or more but if you are looking for a fan that you can use indoors the range would be from about 60-100 CMM. Speed Fans rotate at different speeds which is responsible for the cooling it delivers.
This is measured by RPM or Rotations Per Minute. So, the faster the fan spins, the faster is the cooling. There are two types of pedestal fans available: Normal and, A pedestal fan with 1300 RPM would be considered normal whereas anything around 2100 RPM would be considered High Speed. However, a good RPM range for indoor use at home would be anywhere between 1300-1400.
Durability One of the main factors that decide the is the material that it is made with. It could be plastic or metal. The ones made with plastic are lighter which makes it easier to move from one place to another whereas the metal ones are more sturdy and durable.
- Consider the hours of usage, chances of rusting and maintenance needs, etc.
- Before making the purchase.
- Size When you select a pedestal fan, it is very important to keep in mind the physical space it will occupy in your home.
- To gauge where to place your fan, always check the blade sweep and height.
- Sweep is the diameter of the circle that is created when a fan spins.
The sweep size and height of the fan should match and fit comfortably in whichever room you intend to place the fan. Another aspect would be to also look at the size of the room you are placing your pedestal fan in. If the room is bigger and the fan needs to cover more area, naturally the height would also have to be adjusted accordingly.
- Noise factor Heavy fans with more output tend to make more noise and force you to choose between performance and the silent factor.
- So, do remember to test the fans on multiple speed modes to check if they are noisy or not.
- For example, some newer models like Crompton’s SilentPro Pentaflow fan come equipped with silencing technology which makes pedestal fans a great option for night time as well.
Convenience Pedestal fans have always been viewed as a generic household appliance with little or no scope of improvement. But with newer and more innovative technology, Crompton has introduced like Hi Flo Aveia, etc which are pedestal fans with remote control function.
This helps you get cool breeze at the click of a button! Affordability We know that sometimes household appliances like pedestal fans can seem like they are unreasonably priced but if you look at all the various features, benefits and the convenience it offers it surely is more of an investment for the future.
Due to its portability and size, it can be used not only indoors but also outdoors throughout the year. So, we hope that before you make a purchase, you will consider these points to help you make your decision.

What is high speed fan?
About High-Speed Fans – High-speed warehouse fans are the type of device that most, if not all, of us are intimately familiar with. From hand-held models to desk fans, table fans, and ceiling fans, you can find just about any kind of fan to match your needs and tastes.
- The purpose of these types of fans is to blow a focused amount of air directionally and most often can benefit only one or two people at a time.
- Most have either three or four blades and tend to be used in close proximity to the user—typically within a few feet.
- Even household ceiling fans are usually less than ten feet away.
Speeds vary significantly, but most high-speed ceiling fans spin anywhere from 200 RPM (revolutions per minute) to around 380 RPM. In general, smaller fans spin faster, and larger fans rotate slightly slower as they increase in size. Why does speed matter? For smaller, high-speed fans, a higher RPM will blow air a longer distance and provide circulation for a larger area.
How is speed controlled in a table fan?
How can the speed of a table fan be controlled? Option 2 : By controlling I/P voltage Free 75 Questions 75 Marks 60 Mins
Voltage control is the most popular method of speed control of induction motor-driven fans such as table fans. This method controls the input voltage appearing across the fan terminals. Theoretically, fan torque is proportional to the square of the voltage applied.
Popular three methods of voltage control are listed. Resistive/Rheostat control:
In this method, a variable resistor is connected in series with the fan. At full speed, the resistance is zero. The speed can be varied by varying the resistance by turning the knob (Usually by steps). This will cause some voltage variation across the resistor and the fan will rotate at a different speed. This method is not used now a days due to resistors are bulky & high-power wastage across resistors.
Capacitor Control :
It is becoming popular now a days. It is very similar to resistive control but less bulky and energy-efficient. A variable capacitance in series (usually few capacitors connected together with some tapping corresponding to each step) is used in this regulator. As we turn the knob the capacitance changes and it varied the voltage available to the fan. This will change the fan speed. There are no heating problems and the capacitor improves the power factor of the circuit.
Electronic regulator :
This utilizes power electronic devices such as Diac and Triac (they are essentially semiconductor switches). They chop the supply voltage waveform and reduces the effective voltage. It is like turning on/off the circuit at regular intervals (100/120 times in a second). These controllers are termed as AC full-wave regulators. They are energy efficient as losses are negligible. The speed can be reduced by changing how much time the waveform is turned on and off. A fan at lower speeds consumes lesser energy.

Is 1000 RPM fan fast?
The normal fan speed for a laptop or desktop computer while idle can vary depending on the hardware configuration, ambient temperature, and fan settings. In general, fan speeds between 1000-2000 RPM while idle are considered normal for most desktop computers and laptops.
Is 3500 RPM fan bad?
The optimal speed is the minimal speed at which the CPU and GPU’s temperatures are managed to a safe range. So the optimal speeds are low for idle, and high while gaming.3500 and 2700 RPM do sound pretty high for idle, but it depends on the design of the fans, and could be perfectly normal.
Is 1800 RPM fan speed good?
What’s the Ideal CPU Fan Speed? – Typical CPU FAN Speeds depend on the dimensions of the Fan. Larger Fans rotate slower than small fans, while pushing the same amount of air. Larger Fans are also quieter, thanks to lower RPMs. Here are typical CPU FAN RPM Ranges depending on the Fan Size of your CPU Cooler :
- 140mm Fans: ~400 – 1200 RPM
- 120mm Fans: ~500 – 1500 RPM
- 92mm Fans: ~600 – 2000 RPM
- 80mm Fans: ~800 – 2500 RPM
- 92mm Intel Laminar RM1 (Stock Cooler): ~600 – 3150 RPM
- 92mm AMD Wraith Prism (Stock Cooler): ~600 – 2800 RPM
Your typical CPU fan speed ranges from about 600 RPM to 3000 RPM. However, for a clearer picture, check your CPU Cooler’s Product Page. The ideal CPU FAN Speed is a middle ground between:
- Higher Speed / RPM = cooler CPU = higher CPU performance, and
- Fan Noise / wear
There are diminishing returns the higher your Fan RPM. A CPU won’t be cooled twice as well if you double your CPU Fan RPM. This is because there are more factors at play than just the CPU Fan Speed. The Radiator, the thermal paste, the ambient air temperature, the heatspreader, heat-pipes, and more, are all responsible for cooling the CPU.
- 140mm Fans: 600 – 800 RPM
- 120mm Fans: 750 – 1000 RPM
- 92mm Fans: 1000 – 1300 RPM
- 80mm Fans: 1250 – 1600 RPM
- 92mm Intel Laminar RM1 (Stock Cooler): 1575 – 2100 RPM
- 92mm AMD Wraith Prism (Stock Cooler): 140 – 1850 RPM
Is fan speed 100% ok?
There is no reason other than noise to not have a fan at 100%. The power they use is insignificant, and an electric fan is designed to run at 100% speed 100% of the time.
Is it okay to use 100% fan speed?
No, it will not damage your graphics card. However, you might end up shortening the lifespan of your graphics card’s fan(s) if you run it at 100% for a long time.
Can fan speed be too high?
Reasons the Speed of an AC Fan May Need to Be Adjusted – If your AC seems to run constantly and it takes hours for it to cool your home to the desired temperature, there is a chance that your fan speed is set too low. Setting the fan speed to higher will speed up the rate at which the system cools since it will circulate more cold air at a time.
- However, the primary reason that an AC fan may need to be adjusted is due to high indoor humidity.
- High humidity can be a major issue in Puyallup due to our rainy, muggy weather.
- Your air conditioner helps to combat against high humidity by absorbing and removing moisture from inside the home.
- If it only takes your air conditioner a few minutes to cool your home each time it runs, it won’t be able to have much of an effect on indoor humidity.
The system obviously only absorbs moisture when the fan and condenser are both running. This is why you should never leave your fan on when the AC isn’t running. If you do, it will cause the moisture on the evaporator coil and in the condensate drain system to evaporate again.
This means that the fan will then start pumping humid air throughout the house. The more your AC runs, the more humidity it will remove from the air. This is why in humid climates it is usually recommended that the system runs at 350 CFM per AC ton. By slowing the fan speed, you will also slow the rate at which the system cools.
This means it will take longer for your AC to cool the home to the set temperature. As a result, the system will remove far more moisture to prevent issues with high indoor humidity. In dry climates, your AC shouldn’t have any issues if the fan runs at a higher speed since there will be less moisture for the system to deal with.
Which motor is used in table fan?
Table fan uses single phase induction motor. It also has split phase or CSCR (capacitor start capacitor run) that helps provide an initial torque for the motor to start or run.
Why is my table fan running slow?
Here are some common reasons why an electric fan might slow down: Overheating: If the fan’s motor or other components overheat, it can lead to a decrease in performance. Overheating can be caused by factors such as excessive dust buildup, blocked air vents, or prolonged operation without proper cooling.

I noticed the max fan speed was 6750rpm on CPU fan while the max temp was only 51c at most. I have Asus board with Q-fan, if I disable it the fan will just blow at max speed all the time. Now with it on it basically keeps at 4600rpm on idle and up there in 6000’s on load which gives it a really loud whining noise.
I’ve checked the temps at which the Q-Fan starts to kick in and I’ve set them to 48c and max speed at 58c though it doesn’t seem to make a difference. SpeedFan can control the fans if I disable Q-Fan but I’d like to handle this without having a third-party app start up with windows.
I’m asking if this high RPM harms the fan during time or should I buy a new aftermarket HSF or some kind of fan-speed controller? Joined Oct 30, 2010 Messages 279 Unless I’m missing something your sensors are wrong.6000rpm is an impossibly high speed for a fan, top speed Delta fans are less than 4000rpm.
Joined Apr 25, 2003 Messages 2,244 Joined Aug 10, 2008 Messages 2,512 I don’t care if the sensors are wrong but the noise is still ear piercing. Joined Dec 16, 2009 Messages 1,228 Joined Aug 10, 2008 Messages 2,512 Think I slowed it down a bit by lowering the Q-fan auto mode voltages to 4.0. Fan is at 3800rpm on idle which would be acceptable for on load fan-speed. Joined Mar 2, 2010 Messages 3,484 If you are using a stock AMD heatsink then over 6000rpm is possible.
In fact my 1090T is currently running at 54c and the fan is screaming at 5900rpm, the highest i’ve seen and heard mine is 6720rpm at a temp of 62deg C. The only solution is to get a good HSF Joined Aug 10, 2008 Messages 2,512 Indeed it’s the stock HSF, I just got this mobo and cpu yesterday but I suppose I’ll shop for a new one.
Any suggestions for a new hsf? Joined Oct 30, 2010 Messages 279 Well that shows you how much I know,6000rpm on stock AMD?! Bloody hell lol. Joined Sep 13, 2008 Messages 22,414 yes if you’re using the fan controller on your board it will ramp up to 7000 RPM’s when temps hit 60C+ if you turn off your fan controller in the bios the fan will sit at 3800rpm’s 100% of the time making it almost dead silent.
- Downside to this is that it cant keep the processor cool at full load but if your processor never hits full load then it doesn’t matter.
- I suggest going out and spending the 20-30 dollars for a sunbeam core contact freezer or a coolermaster hyper 212+.
- Best investment you could ever make and should last you through a few processor upgrades.

I’m asking if this high RPM harms the fan during time or should I buy a new aftermarket HSF or some kind of fan-speed controller? As others say, I recommend that you go out and get a decent air cooler. That Thuban is just waiting for you to crank up the clocks on it, but you need a very good air cooler first.
The stock PII cooler maxes out at upto 7000rpms, and you’ll know it when it gets that high as it gives new meaning to a “dust buster.” It is ear piercing deafening loud. I can’t imagine why you would want to run your fans at high speeds all the time as it is loud enough to be uncomfortable. I would also imagine that it could decrease the life of the fan, although the fan was designed to spin upto those speeds and shouldn’t be damaged.
I would leave your motherboard’s onboard cpu fan controller alone to work by itself as it should do a decent job as long as you don’t turn it off. Thubans are safe for temps upto 62 degrees or so, and your motherboard will adjust the fan speed accordingly.
On my PII 965 in the gaming rig, the motherboard will ramp up the fan to around 2800 by 55 degrees, 4000rpms by 58-59 degrees, and upto 6990 rpms by the time I get to 62 degrees on a very hot day.

- You misunderstood, I don’t want to keep the fan at 7000rpm on load, but yesterday managed to lower it by a 1000rpm by lowering the voltage.
- Also I can’t seem to overclock past 214 x 14.0 @ 2.98 Ghz which I was trying to figure out here http://hardforum.com/showthread.php?t=1577261 Joined Jul 21, 2010 Messages 51 There’s no way around it really, if you lower the speed of the fan too much then the cpu will just overheat.
Like monkey said, the CM Hyper 212+ makes for a decent inexpensive cooler. Worry about overclocking after you get your temps down. Joined Aug 10, 2008 Messages 2,512 Yeah the thing was I didn’t even want to get a new HSF if I couldn’t overclock properly. Get those load temps under 50°C and you could reach 4GHz. Joined Oct 30, 2010 Messages 279 Bearing in mind I know nothing about AMD CPUs.is the stock heatsink just so rubbish as to need 6000rpm on the fan? Or are the processors just rather inefficient? Joined Aug 10, 2008 Messages 2,512 I guess it’s the combination of both.
I’m trying to place an order on the 212+ but my bank’s website is down due maintenance so I can’t pay it. Edit: There we go. Should arrive sometime next week. Joined Mar 5, 2010 Messages 575 Bearing in mind I know nothing about AMD CPUs.is the stock heatsink just so rubbish as to need 6000rpm on the fan? Or are the processors just rather inefficient? If I’m thinking the right heatsink, it’s the heatsink being absolutely terrible.
IIRC the bad one is basically a hunk of aluminum (and maybe a copper core, but no heatpipes) Joined Jul 2, 2008 Messages 896 Good god, my Freezer64, which is probably not much better than the stock X6 heatsink/fan, idles at around 800 RPM at 34C, ~1000 RPM 50C at full load when folding.
Joined Jul 21, 2010 Messages 51 The stock AMD heatsink is still basically the same size since the Athlon XP days. They did put in a copper base and heatpipes for the high end Phenom chips but still use a paltry 70x15mm fan and it has to spin that fast just to keep em cool. Joined Oct 27, 2004 Messages 4,880 Bearing in mind I know nothing about AMD CPUs.is the stock heatsink just so rubbish as to need 6000rpm on the fan? Or are the processors just rather inefficient? If the temperature inside your computer case is reasonable, there should be absolutely no reason why the fan should have to spin up to 6000+rpms on stock clocks/voltage.
If the fan has the spin up that high and you are running stock or near stock, then you might have issues. The stock HSF on the AMD PII’s are actually not all that bad and do a good job if you are willing to put up with the noise at higher fan speeds. I am running at 3.5ghz on my 965 at stock voltage, and it has only exceeded 6000+rpms when the computer room temperature got extremely hot during what was an extremely hot summer last year. Joined Jan 4, 2005 Messages 594 6000rpm?! Geez, my Scythe Ultra Kaze’s top out at half that, and by then there’s some serous airflow going on there. Sad thing is, I bet they push more air on low than that AMD thing on high =P First thing to do is get good cooling.
What are the benefits of a high speed fan?
Energy efficient As the name suggests, this variety of high-speed ceiling fans deliver great air circulation while consuming less power. They are great power savers that help you cut down a lot on your electricity bills. These, too, come in many designs and colours.
What is the difference between a high speed fan and a normal fan?
If everything else is equal, a high speed fan will have a higher output power than a low speed fan. One electric fan to another will have similar efficiency. Therefore, the high speed fan will use more power than a similar fan at low speed.
