do i need pwm fans?

PWM usually merely offers increased functionality ranges (some going as low as 20%). but no. you really don't need PWM for case fans. whether or not you want better case fans is up to you, but to make that decision solely on using 3 pin or 4 pin fans is largely irrelevant.

No, 300W PSU should be enough for a single core Celeron CPU, with integrated GPU. You must make a sum of all component power requirements, but also have in mind all power supplies have around up to 80% power efficiency.

Can PWM fans be voltage-controlled? Noctua has 3 pin fans too, but yes, 4 pin fans can be voltage controlled as well, they were designed to be backward compatible.

For example, if you're building (or buying) a PC with a Ryzen7 Series CPU, an Nvidia GeForce RTX 2060 GPU, 16 gigabytes (GB) of RAM made up of two 8GB sticks, a 256GB solid-state drive (SSD), and a 1TB 7200RPM hard disk drive (HDD), then 576 watts of power would be recommended.

"power fan" header is usually found on most mother boards. This fan header does not have any ability to change the speed of a fan connected to it. It supplies the full standard 12V to the fan at all times. You won't find any option in the BIOS or ASRock utility to adjust a fan's speed when connected to it.

PWM fans are typically capable of going to much lower minimum speeds compared to DC, they can typically dip down to 20% or lower. Whereas DC is typically in the 40-60% range for minimums. DC controlled fans require a minimum voltage to spin continuously. The minimum voltage threshold varies depending on the fan model.

Your motherboard probably uses 50 to 150 watts, and each stick of memory requires about 15 watts. The processor needs between 80 and 140 watts of power.

Even PSUs with thermal throttling will be spinning at some speed. If a computer didn't have any extra fans, the one you know will always be there is the PSU, and that is the single source to circulate the air in the PC. So unless you intentionally buy a fanless PSU, the fan should always be moving.

Commendable. I used them in the front to help with AirFlow thru the HDD cages , works well and they have RPM adapters to slow them if you want to. I love the look , so I have 5 installed , only front aren't being slowed by adapters , temps are great , good airflow. They are solid well built fans.

NVIDIA RTX 2080 Ti: Minimum 650W. We recommend at least 800W.

Virtually all PCs and monitors use the standard 'kettle' lead connector for power. Typically you'll need two power cables, one for the PC and one for the monitor.

Table fans use relatively less power to run compared to the typical ceiling fans. Common table fans use 50 to 55 watts of electricity as we can find in the market. The high-speed variant of the table and stand fans use more power to run- about 65 to 110 watts.

Well problem only may occur if you use it non-stop like high moisture in air, soo it wouldn't be a problem only if your pc isn't watercooler, if its classical fans, then you can use it, but still i would check for moisture in case after a week, if there is no moisture after week then you can use it normally.

As against PWM and PPM has low noise interference factor because their noise immunity is high. In PAM and PWM techniques transmitter and receiver, synchronization is not required. But PPM technique needs synchronization between transmitter and receiver section.

As fanless units we've seen so far don't have a particularly good track record when it comes to reliability. Fanless PSU are a Niche for very select customers. YOu'd probably be fine with a lower noise PSU like be quiet Straight Power 11.

Yes, if you buy a retail pack, no if you buy OEM version. It is generally worth buying your own fan and heatsink anyway.
