Cleaning a mobo

[Guest]

Electronics Repair Man,

I was interested in your comments about the 120 volt DC case fans. I was
considering using 120 volt AC case fans but I was not sure how the
motherboard and other components of the desktop PC would react to EMF(?)
from the wiring. I figured something like this might be a good option for
those of us with marginal power supplies and requiring more air flow. Your
comments (and others as well of course)?

About my last post, I actually meant AC not DC.

>"It does restrict the movement of air."

This should of read, It does restrict air movement but it isn't significant.

The Electric Magnetic Force (EMF) is nothing to worry about, since most
component are shielded from this. And the EMF isn't really significant.

I hardwire the fan directly in the Power Supply (550W) where the power comes
into the power supply after the power supply switch. So when turning off the
Power supply, the fan would power down. Also when the Computer goes into
Standby the fan will still run but I do not mind this at all because the CPU
atcually climbs in temparature for a few minutes when powering down due to
the CPU fan not running after entering Standby mode. I used a 4" Fan, but
mounting it was not that difficult. I had to drill 4 holes to mount the fan
correctly. Usually inside a PC case you use a 3" fan. The filter is a must
because alot of dust will travel with air flow. The filter should be cleaned
a regular basis due to the increase of dust. I have found the temperatures
for the System is usually around 28 Celcius instead of 30 to 35 Celcius. The
cooler the system, the more stable the computer will be.

I have always wonder why manufacturers do not use this option. These fans
tend not to fail as often.

We use 110 V AC fans all the time in many electronic equipment, like Video
Receivers/Transmitters for Cable providers and Audio components. The EMF is
not a issue, they do not cause interference to components. And in these
components, there are many microprocessors to process data and encode them
into transmitable signals or to decode signals.

If you have specific questions or details feel free to ask me. I rarely
check my hotmail account due to SPAM. Just post here and I will answer as
quickly as I can.

Electronics Repair Man,

planning on doing as well.

Thank you for the great info.

Distilled is the process of taking those impurities out of the water 😉
