Fan for UPS
« on: November 26, 2015, 12:08:50 am »
The Fan got louder over the Time. Normally for other Stuff I take Pc Fans but on this Time not a god idea.....

Original Fan: http://www.nmbtc.com/fans/part-numbers/DC-Axial-Fans/3110KL-04W-B50-G00/3869

Can someone recommend an Silent Fan?
The Major Problem is a 2Pin Connector and the cable must be short <10cm and there are a lot of Hot and 230V Parts around.

... They come in a variety of speeds, blade configurations, and sizes, with 'power' ranging from 'butterly fart' to 'tornado'.

It's a fan. Go pick one you can source and fit it.

When replacing a fan always make sure airflow and static pressure are at least similar on the replacement fan. There are huge differences but a higher quality fan can be quieter while providing the same airflow (and pressure).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Noctua fans are reasonably cheap and come in various loudness and flow ratings.  Or any two or three pin PC fan with double ball-bearings will probably be ok if it claims to be quiet and high airflow, because you are already paying a premium for the bearings.  Get it from any PC parts place, should be less then 15 euros including postage from your country or next door one.  Cut the leads 3 cm from the fan and splice on your existing leads (in case they are heat resistant) with heat shrink over the splice.  Just use the relevant two leads if it is a 3 pin fan and insulate the remnant of the yellow one.

I think CoolerMaster Blade Master 80 may be close to your needs: http://www.coolermaster.com/cooling/case-fan/blade-master-80/

Amazon link : http://www.amazon.com/Cooler-Master-Blade-80-Computer/dp/B0030DSECK  and Newegg link : http://www.newegg.com/Product/Product.aspx?Item=N82E16835103071

but since you're from Austria, you'd probably be better if you find it at some European store , or try amazon.de / amazon.co.uk

   If three 100  Ohm resistors are connected in parallel, and in series with a 200 Ohm resistor, how many resistors do you have?
