I hate those noisy fans!

[Shiva]

Hi,

My PC produces quite a lot of noise, especially if its CPU usage exceeds
(approx.) 20%. Thus the CPU's fan is causing most of the noise.
Can this be replaced by a less noisy fan or (better) something that doesn't
produce any noise at all.

Motherboard is a ASRock P4VT8, the processor is an Intel Pentium IV 3.4
Ghz.

Any suggestions?

Thanks a lot.

Have a look at:

There are lots of products to cool your PC quietly. A new silent PSU. A new
CPU heatsink and fan. Quiet case fans to keep the case cool.

Do you know your room, case and CPU temperatures. The difference between
these temperatures will tell us what needs attention. If your CPU fan is
spinning loudly, then the case could be too hot and you can't cool a hot CPU
with hot air!

Do you know your room, case and CPU temperatures. The difference between

Room temperature is between 17 C (winter) and 28 C (max. in summer). The
temperature of the case is about 34 C.

According to a monitor utility, CPU temp. is always 38-44 C. The room
temperature is always a lot lower, so I should always able to cool it with
air, shouldn't I?

BTW, the fan's spinning seem to depend on the CPU (usage). As soon as CPU
usage increases from 2 to 20% (or more), the fans almost immediately start
to spin faster . This method keeps my CPU cool, but programs requiring lots
of CPU power will cause the system to produce a hell lot of noise.

You might find that adding a case fan or two will help things. The case
temperature is not particularly high, but given the room temperature, it
could probably be reduced 2-5 degrees. CPU temperature is fine, so your
cooler is working well, but if the noise is bothering you, I would recommend
adding a case fan to exhaust air from the case. If you already have a case
fan and have space, then add another exhaust fan and consider a fan to suck
air in at the front of the case. You can get pretty quiet case fans. At the
same time, you could consider replacing the heatsink and fan with a quiet
operating device, such as a Zalman

usage increases from 2 to 20% (or more), the fans almost immediately start
to spin faster . This method keeps my CPU cool, but programs requiring

of CPU power will cause the system to produce a hell lot of noise.

This is quite normal. The fan will be activated, or turned up according to
temperature, which rises with workload, but if the surrounding air is
cooler, the heatsink will work more efficiently and cool the CPU more
quickly and the fan might not need to kick into high gear so fast, or for as
long.

Try running the PC with the side off for a day and see if the CPU fan jumps
into high as often. If it does, then you could change it. If it stays quiet,
then you could fix the noise with more case cooling. By the way, everything
will sound louder with the case open (obviously).

There are many ways to deal with this problem. Here's one that we
implemented, so you will be getting the benefit of our experience. My
son has a P4 3.2 GHz Prescott Retail Box CPU. It ran too hot so we put
a Zalman 7700 on it. You could cool an Atlas missle with that thing.
We did not use the Zalman-provided speed control - the fan runs flat
out.

Then we put 3 Panaflo fans in, one in the front, one on the side and
one in the rear. This is in addition to the PSU fan.

http://store.yahoo.com/directron/80l1a.html

Both items were recommended by the head of the technical department at
Directron, so we had the benefit of his experience.

The upshot is that for under $100 my son now has a relatively quiet
machine that runs cool, even when running DVD Shrink (which is
probably the most torturous application I have ever seen).

I think I also go for a Zalman fan. It's also recommend by lots of other ppl
as I found out.

I'm running applications like Terratec's Cinergy 400. This program records
TV-programs and converts them real time to formats like DivX. It requires
about 35-40 % of CPU-usage. After running the application for a couple of
minutes the fan is spinning at more than 5200 RPM, which is very noisy (and
annoying!).
The Zalman's fans spin at 1000-2000 RPM, which is very quiet, I reckon!

I cannot say that the Zalman 7700 fan is very quiet - you can hear it.
But then we did not install the unit that comes with it - called the "
FAN MATE 2".

Also, make sure you have the necessary clearance to fit that monster.
And use silver paste.

These fans should do the trick:
