Help needed to change CPU

[lavenders19]

My old computer is a HP Compaq EVO desktop 530 P4 2.4 and very quiet.
I have just bought a new 2nd hand homebuilt P4 3.0 with a ASRock P4VT8+
motherboard 478 socket which is very loud. Both the power supply fan
and another fan are very loud and I cannot bear the sound. Is this
normal for homebuilt systems?

That said, I want to transfer the P4 3.0 into my HP Evo with the 400
speed RAM to improve that as I need the quietness.

How do i change the CPU, I see it is covered with a fan, so do i just
remove the fan and unplug the chip and replace with new ones. Is the
HP Compaq EVO a 478 straight fit? and will the computer automatically
sense the 3.0gig speed.

Any comments greatly appreciated. Many thanks in advance.

It is if you buy cheap stuff.

Yep.

Should do.

Make sure the new fan/heat sink is compatible with your motherboard. Go
to your ASRock site and read there. The retail fans that come with the
CPUs are sometimes considered noisy. I just bought a Sempron 3000, and
the fan on it is fine. It does say however that changing the
fan/heatsink will void the warranty. You might need thermal paste
between your CPU and heatsink. Do some research on this.

So how exactly will it come off. The fan has 2 clips on the top. If i
unclip the fan first, will it lift off leaving the heatsink and the
chip in place or will everything come off. If only the fan comes off,
are the heatsink and cpu glued together? Does the cpu have any catches
like the RAM or does it just plug in and out?

I love the noise it keeps the mice out of the machine

I am not sure about that socket, but it might have a little lever
(probably the length of the socket), that you raise and the socket
releases its "grasp" on the pins, and it should come out easily.
Actually I have never take any out, just insalled a few. These sockets
are typically called ZIF (zero insertion force). I assume removal force
is miniimal as well. I can't answer the "glue" question, but I doubt
the it should be.

It's the CPU fan on the 3 GH CPU that's so loud, because that CPU was poorly
designed and runs VERY HOT. So the fan runs at high speed and is loud.
Moving it into your HP case will NOT quiet it down.

I don't think that moving the proc to the HP case will really help. But, if
you do move the proc and it's using Intel's stock Heatsink/Fan I've had
trouble with the grey thermal pad pulling the processor out of the socket
(with the zif socket lever still in the locked position) and on occasion it
will bend some pins. I would suggest making sure you pull the Heatsink/Fan
straight up and not off to one direction. Someone else on this group might
have a solution as to how to get the thermal pad to let go of the proc.
Just a little warning.

A lot of folks have not installed the I6xx processors yet (unless you
are a builder) so I will add a bit of info. They don't have pins at all. The
processor has contact points (775 of them) on the bottom of the processor.
They mate with contacts in the socket and are then clamped down securely so
there is almost no way that a HS is going to pull them out. The HS contacts
the processor between the retainer that holds the processor down. There are
four plastic expansion screws (Intel type HS) that need about 1/2-3/4 turn
to secure them. They are easy to break. Most after market HS' use "through
the board" type mounting that IMO, is better but more trouble because you
need to remove the MB. Getting the Intel type HS mounted so that it makes
good contact with the processor is one of the main issues for the home
builder. There are good instructions included and if you follow them it
isn't difficult. One thing that was left out is that by tightening one
corner, then the opposite corner and repeat for the other two is easier, for
me anyway, to get a good mating of the processor and HS. Good case airflow
is a major issue in getting decent cooling on these things. It may be
because the processor socket is a bit higher than previous P4s and closer to
the PSU, at least on my board (Asus P5GDC) it is. It may take a bit of
experimenting to find the best solution and it isn't always more fans, it is
getting proper airflow across the HS/fan unit.

Which is great, but the OP said he was using a Socket 478 proc not the newer
775's.

Your are exactly right and I got this thread mixed with another.........
Bad day. Thanks for the correction.
