This
morning I was doing some computer renovation.
It starts as a routine case dusting;
these full server towers are dust magnets, you
know. While
I am dusting the power supply, I get this bright
idea. I
decide to put in a fan that pulls more air.
A larger fan not only adds to the cooling
potential of your computer but also adds a nice
exhaust note to it.
However, this article is not only for the
cooling enthusiast, it can be used to replace a
fan that wigged out on a perfectly good power
supply (this has happened to me before).
In today’s market, good reliable power
supplies come at a pretty steep price, while an
80mm fan, some knowledge of electronics and a
little ingenuity will save money and provide an
adventure at the same time.
Before we
go any further, I must include a disclaimer.
While this operation is relatively safe
for you and your computer, you should be
informed of the inherent risks.
First, wisdom is harnessed by good sense.
So if you do not have much experience
with electronics, I ask that you refrain from
doing this operation yet.
Secondly, most power supplies will have a
seal that if broken will void your warranty.
This has two implications.
If during this process, your power supply
stops working then you will have to buy a new
one. Further, if your power supply surges and it damages your
computer, you will not be able to claim money.
Both of these scenarios are highly
unlikely since you will only work on the fan.
Finally you are operating on a power
supply, which can give a very severe shock if
you do not follow some basic precautions.
I ask that you unplug your computer;
leave the power supply plugged in to the
motherboard and let it drain the capacitors for
at least thirty minutes.
Even after this time, do not probe around
the power supply, since we are only working on
the fan. Pham
Computer and I do not warrant and are not liable
for any personal injury or any property damage.
You proceed at your own risk.
