You should also be able to hold the psu outside the case while still connected and then power your computer up. As can be seen from the chart, if a power supply's fan is operated with a high exhaust air temperature at perhaps 80°C (176°F) its life expectancy may be a short

All the system temps are well below threshold and like I said noise doesn't bother my daughter. The Athlon XP 3500+ could almost run without the cpu fan just the heatsink connected. Leave bottom point uncut as shown in green rectangle), Band the green point to downward ,lubricate fan , rebend the strip back again in original place. Psu Making Buzzing Noise Checked temps through SIW.

This speed control is not so much for heat control, but for noise control. Power Supply Fan Not Spinning But the boxes and manuals and stickers were already printed - so instead of throwing tens of thousands of dollars in printing away, we just used the stuff we already had. My new tx650 started ticking about two days ago.. http://www.tomshardware.com/forum/293354-28-power-supply-constantly-running-high-speed For help determining which fan is making noise, see Step 3: Determine which type of fan is making the noise.

Cooling fans equipped with either two- or three-pin connectors are usually designed to accept a wide range of input voltages, which directly affects the rotation speed of the blades.

Volt modding[edit] The voltage a computer fan receives is defined by the difference between the voltage wire (+12V) and the ground wire (+0V). http://www.help2go.com/forum/computer-help/104658-power-supply-fan-erratic.html By connecting one or both wires to a different voltage, the voltage the fan receives will be different from the default 12V the fan was designed for. Power Supply Fan Noise If the fan is still noisy, continue to the next step. Power Supply Making Grinding Noise Although if it's not doen it before, then not sure.

Most allow you to simply monitor the PSU fan's speed. The noisy fan is the largest fan on the main circuit board inside the computer.

Integrated or discrete linear regulators[edit] Common voltage regulator ICs like the popular LM78xx series are sometimes used to provide variable or constant voltage to fans.

The combination defined in claim 3, and which includes a variable voltage divider connecting said emitter electrode to said negative output terminal, and having a movable contact connected to said shunt Turn on the computer and wait for Windows to open. This current may be adjusted by adjusting the potentiometer R103 which changes the division ratio of the variable divider. Power Supply Making High Pitch Noise Efficiency Calculations for Power Converters A power converter's efficiency (AC-DC or DC-DC) is determined by comparing its input power to its output power.

Use a vacuum cleaner to remove dust from the power supply vent on the back of the computer. Because depending on the whine it is a unit to unit variance in the construction?

When I was working as a tech and doing many machines a day, it saved me hundreds of hours of time, and saved the customers countless amounts from not having to Unlike linear voltage regulation, where the fan voltage is proportional to the speed, the fan is driven with a constant supply voltage; the speed control is performed by the fan based Yes, my password is: Forgot your password? Have you tried running the computer with the side off the case?

In order to actually disconnect the PSU fan, you would have to open the PSU case - and that should only be done by a qualified (not "so called" ) technician
