How Critical Is Power Supply FAN?


And it’s strategically located in front of the vents that lead to the outside of your computer case. Ball bearings have more longevity and cost more, sleeve bearings may be less expensive and their life expectancy is considered much less than a quality ball bearing Fan Speeds to Dissipate Otherwise, why derate at higher temperatures? This will help prevent the PSU intake fan from sucking in carpet fibers and helpless dust bunnies caught in the crossfire.

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 heat. A few in the Yahoo! you forgot something...Like you said, yes load temps are the issue for you, so...

Determining Which Way Your PSU Fan Should Point The direction of the PSU fan is crucial for airflow. The Enermax specification about its operating temperature states: 0' C ~25'C for full rating of load, decrease to zero watts O/P at 70'C If the output capacity of the unit drops

  • But that again depends on the case airflow.

Power Supply Fan Definition

My NZXT case has PSU at the bottom too, but it has a PSU vent at the bottom and a mesh filter over the vent. If not, disconnect the power cord immediately. What Is A Power Supply Fan That’s because your power supply is far more than just an unassuming gray or black box that you plug into an outlet before you crank up your computer. How Does Power Supply Keep Cool You can contact PSU manufacturers like Corsair, Enermax, etc or even email this guy http://www.jonnyguru.com who knows a thing or two and see what he says.

The concept is that the psu would help cool the interior of the case by drawing in warm interior air and exhausting it out the rear of the case. JohnnyLuckyFeb 4, 2010, 9:56 AM yiplong - Which case do you have?All modern power supplies exhaust air out the rear of the psu case.

There are also variable-speed fans that increase or decrease the fan's speed depending upon the sensed ambient temperature or the load required of the power supply. Purpose And Roles Of Fans In Power Supply Most fans use +12 V power to operate, despite the fact that the wires that run to them are normally red for the +12 V line, and black for the ground When the current drawn from a particular output increases or decreases, the voltage changes slightly as well, usually increasing as the current rises.

Overvoltage Protection prevents a signal from being received if the voltage exceeds a certain limit.

Once you’ve got things squared away, your PSU will be breathing happily. Graphics/CPU both started running 20-25 degress cooler than before and no more smell. What CPU fan?3.

To finish off dealing with you (probably a 10 year old) http://www.frozencpu.com/help/h32/Power_Supply_FAQ.htmlAnd read the part where it says:"Does temperature affect your PSU's output efficiency and life span?Temperature greatly affects the life Based on my test above, mounting the PSU facing up has little effect on the components, except that CPU idle temp is 6c higher in this case, (that's significant, but CPU Are you sure it is the same for all fans? http://magicnewspaper.com/power-supply/graphic-card-power-to-power-supply-or-connector-on-motherboard.html Re: PSU recommendations?

If you've added a lot of new components to your PC, you may be overtaxing your existing power supply, so look at getting a bigger, better one. With faster and hotter processors becoming the norm, maintaining optimal temperatures is critical for the smooth running of any system, and overheating of a system often causes irreparable damage to the Hot air will rise pushing cold air down, regardless of whether or not air is flowing through the case, and this movement is airflow. A bottom mounted PSU even fan facing up will draw in far less hot air than a top mounted one b/c hot air rises.

So your idea sounds plausible at first glance, but it is actually nonsense when you think about it.
