generally the noisiest fans are the small ones that spin very fast as
opposed to the larger slower moving fans - if I want to tell where the noise
is coming from I put my finger very gently on the hub of the fan to slow it
down just for a second and listen. If you're using a retail CPU that came
with its own heatsink - those are generally poor quality in terms of cooling
efficency and noise. A third party cooler is usually better.

Cool n Quiet is designed to slow the CPU down when its not being stressed.
Its a power saving feature and besides - you dont need 3ghz to do word
processing do you.

Your 7025/930 is an intergrated graphics chip. Motherboards have chips to
handle
certain functions like controlling hard drives - generally referred to as
the Northbridge and Southbridge - thats the 930 number. The 7025 refers to
the graphics part. It uses a portion of the system RAM for texture memory
(whereas a plug-in card has its own dedicated memory).
Currently its using 128mb of the 1GB you have installed.
That chipset is okay for web browsing and word processing but its no good at
all for gaming.

Great, thanks. I was hoping to try with the case fan disconnected but
just needed the go-ahead from someone as I didn't know it wouldn't
cook without that. And yes the case fan was the noisier culprit, it's
fine now. So I will enable Cool 'n' Quiet in the Bios and see if it
goes any further, but this is fine now. There are plenty of vents in
the case, more than in my old PC, and plenty of space, if that
constitutes airflow. I'll look into case fans that claim to be silent
later, and that is helpful what was said about larger slower ones
being better. Two inches down from where the case fan is mounted is a
larger vent grill area, 3 1/2" x 6 1/2" where I imagine I could screw
a bigger fan instead.

Can you confirm that a 512 mb graphics card is perfectly fine for my
purposes as mentioned? I'm not a gaming man, but I imagine video-
editing is similar demand-wise, DVDs and online video, including BBC
iPlayer, being the other uses. I see there are inexpensive 1 gb cards
but the price makes me suspicious of other shortfalls I wouldn't at
present understand. I see some have fans on, and maybe I'd end up
there getting some noise back.

Thanks. Cheers.

case fans create airflow inside the case and can make a difference of 10
degrees
- worthwhile if you have a gaming PC with a fast graphics card that
generates
a lot of heat. download some free software like cpu-z, gpu-z and everest to
check temps.
a cpu temp in the 40s is good, in the 50s is acceptable but if its getting
close to 60c
then you need more (or better quality) cooling.

A graphics card will take some of the load off the CPU but with a 3ghz CPU
Im not sure you need to worry. Certainly 1GB of RAM is on the low side so I
would
increase that first and see how your system performs. Always have your RAM
in matching pairs
ie 2x1GB sticks or 2x2GB sticks so that it runs as dual-channel and gives
you the best performance from your RAM.

If that DVD is High-Definition then a plug-in card may well be a good idea
but try the RAM first.
