Most fans make quite a din on their highest settings, but these two are as quiet as church mice, even at full tilt, which makes either of them the perfect bedroom or lounge buddy. Perhaps it’s the DC motor or the structural design (or both), but both models produce a much lower frequency when spinning, and that makes a massive difference to a room’s ambience. Vornado VFAN Jr. Vintage Air Circulator Fan: We love the vintage look of this fan and were excited to see if it is as practical as it is stylish. After testing in our lab, we were impressed with its compact size, durable, steel material, and decent airflow, even with just two speed settings. This fan does not oscillate but it can pivot up and down so you can point it where you need it. However, we couldn't feel the air even at just 6feet away. And although it would be a great addition to your vintage-style decor and does provide some cooling at a close range, we just don't think it's the best option to cool your space.

Since the density of air varies with temperature and pressure the mass flow through a fan varies with temperature and pressure. Type: Bladeless | Speed settings: 4 | Battery life: Up to 9 hours (speed 1) | Battery type: 5000mAh | Dimensions: 5 x 16 x 20 cm | Weight: 274g What we like After testing this fan long-term at home, we found that it was a complete game changer in an apartment, which only has one AC unit in the bedroom. We left this fan running on high and oscillating every day while we worked from home. We sometimes even forgot to turn it off because it operated so quietly. Overall, this fan’s design and features make it a great option for small bedrooms or other compact spaces where you want powerful circulation but quiet operation. If you have the required volume flow for a fan at a reference condition (typical NTP) - the operating volume volume flow for the fan at other operating temperatures can be calculated asAfter testing the Lasko FH500 Fan & Space Heater Combo Tower, we found it to be a great value, with features that can help make a larger room feel comfortable year-round. This 1,500-watt combined heater-fan is ETL-listed, meaning it's certified as meeting the requirement of widely accepted safety standards. It features a bladeless design and tip-over safety feature, so it should automatically shut off if it falls over. While testing, we found this four-speed fan effective at circulating the air, even as far as 20 feet. And at its highest setting, the sound is subtle enough to act as white noise. We also like that the unit has built-in storage for the included remote control. As far as performance, we found that this three-speed fan was quite powerful and relatively quiet when we tested it from 10 feet away. However, we noted that at 20 feet, we couldn’t feel the fan at all, which would be an issue only in larger spaces. You also get horizontal and vertical oscillation, easy height adjustment, a clip-on remote control and two highly effective optional modes that either simulate a natural breeze or tune the fan speed according to the ambient temperature. It’s not the most elegant fan out there, but nothing beats it for large-scale, controllable and whisper-quiet cooling.

ABS and other more temperature-sensitive filaments fare best when the part cooling fan speed is set to 0%. The right Ender 3 fan speed depends on several factors: the filament type, hotend and heated bed temperature settings, and the temperature of the space around your printer. Given that this fan is of the ‘personal’ variety, don’t bank on it cooling a whole room – even a small one – and certainly don’t bank on it purifying anything other than the air immediately around you. But if you’re after a personal high-end fan-cum-purifier that performs well and looks the part, then this one is a worthy, albeit pricy, contender. When space is an issue, a great option is a window fan—this type of fan directly brings in fresh air or exhausts the room air without taking up valuable floor space. We tested the Genesis Twin Fan and found it to be versatile and budget-friendly. You can expand it from 24 to 37 inches to fit your window, and its detachable legs permit it to be freestanding on a table. While testing, we found the fan to be lightweight and easy to move with one hand, thanks to the built-in handle.Fan types and sizes: The Ender 3 has four main fans: part cooling, hotend, mainboard, and power supply. Each fan has different size and voltage options. What fan is the best for most people? Our top-tested model is the Vornado 630 Mid-Size Whole Room Air Circulator Fan. It wowed our engineers during airspeed testing, and we loved its easy-to-pivot head. Additionally, we found that the grill removed easily for cleaning, and the fan passed our safety inspection. For those on a tighter budget who are willing to compromise slightly on airspeed or those who want a quieter fan, we recommend the Honeywell HT-900 TurboForce Air Circulator Fan.

Key specs – Dimensions: 115 x 37 x 35cm; Weight: 6.8kg; Oscillation angle: 120˚; Cord length: 1.75m; Warranty: 2 years; Power: 20W On the top of the fan, you can find thoughtful features, including a magnetic area to store the remote; an LED-lighted control panel that turns off after a minute, so it doesn’t disturb you at night; a 7.5-hour programmable timer; and a handle, so you can easily carry the fan from room to room. In fact, we noted it was so light, we could move it with just one hand. However, we feel that this is not the best fan to travel with because it is not as compact as some other options we tested. While first and foremost a duct upgrade, it’s also an entire system to upgrade almost every component attached to the print assembly. After testing the Vornado 660 Whole Room Air Circulator in our lab and at home, we found it to be a powerful option for any room. Small enough to sit on a desk or dresser, this fan is designed to circulate air up to 100 feet. And although it doesn’t oscillate, while testing in our lab, we noted that we felt the fan’s direct airflow up to 20 feet away. Plus, we loved that you can tilt it up to a 90-degree angle, from horizontal to vertical to point it where needed.

As the app and remote also add scheduling, and a quiet and energy-saving night mode, and show you all manner of graphs about the air quality and temperature, we feel that the Pure Cool does justify its price. There's even adjustable oscillation, via the app. CFM—or cubic feet per minute—measures the amount of air a fan moves every 60 seconds. Generally, CFM depends on the fan’s motor and blades (their pitch, length, and shape). The higher the CFM, the more air a fan circulates. Fans with low CFMs are suitable only for small spaces. As a general rule, 100% fan speed is recommended for PLA and PETG, though the initial layer fan speed should be set to 0% to allow for the first layers to properly adhere to the build surface, free of warping or shrinking issues. A fan is a "constant volume" device where the volume in the fan - and the transported air volume through the fan - is always the same (with same fan speed and size ). The Petsfang also exists in a suitable version if you’re looking for an Ender 3 Pro fan upgrade or Ender 3 V2 fan upgrade rather than the original Ender 3.

However, these are generalizations. The ‘right’ fan speed for your particular Ender 3 Pro should be a matter of experimentation and dialing in until the print quality/strength lines up with your preferences/needs.

While testing in our lab, we could feel the airflow as far as 20 feet on the highest setting. However, we noted that it wasn't until the sixth setting (out of 10) before we started hearing or feeling the airflow; lower, we had to put a hand right up to the fan. We also noted that it is fairly quiet on its highest, strongest setting, so it shouldn’t disturb you at night or while watching TV. In fact, while testing at home, we appreciated the fan's white noise and found that it was louder than our ceiling fan, but not as loud as the AC. Upgrading the Ender 3 part cooling fan requires a new fan alongside a 3D printed cooling duct/shroud. Ender 3 Cooling Fans It’s compatible with all 40×10/20 mm fans, though the project was initially conceived to pair best with Noctua parts. With all this in mind, here are recommendations for both a 40 x 10 mm and 40 x 20 mm Ender 3 Hotend fan replacement: We measure the ambient sound produced by the fan with a decibel meter in a quiet room and compare loudness levels across fans. We assess safety by examining whether a finger or ring can pass through the grate to any rotating parts or pinch points.
