You should run a suitable benchmark to see if it running slow.

I would say not, it will either work or it won't, no halfwayhouse.

Might be, as long as you smell no burning.

According to the picture here, the jokers at FIC (FIC VC35) only installed
one of the two loops on the heatsink. It took some tracking down, but the
motherboard is a "Budapest" with 845 Northbridge.
There are a couple documents for 845 family at Intel, and the chips are
somewhere in the ~5W power dissipation range. Maximum "case" temp of the
Northbridge is 92C. The drawing shows the Northbridge as having a bare
silicon die, like an Athlon.
Just a matter of finding a loop to replace it. Or a "loop compatible"
heatsink like this one. Click the "loops type" button on the
upper right of this Flash movie. Since the arms are a fixed length,
there is no way of knowing whether this will fit or not. Product
comes with thermal paste.

Normally, there would be four pins and two pieces of wire.
One piece of wire like this.

In the picture, I only see one of the two possible
pieces of springy wire.

To me, normal for an OEM heatsink of that era was what was
pictured, I've seen a few Dells like that.
However, it doesn't necessarily matter now, since it seems
one of those loops is missing and has to be replaced or a
surface bond has to take it's place.

Paul, is that fact, urban myth or just humour?
I was given two redundant pcs which used the FIC VC35 motherboard and both
had only two of the loops shown, the chipset heatsink hanging on by one
loop. As I found a loop loose in both of the cases I was baffled as to the
reason and had presumed that this was someones attempt at making the pcs
unworkable before they were disposed of.
These desktop pcs were 4 years old and were/are still working fine.
I'm no dab hand with the soldering iron and after my first attempt the loop
pulled out within a couple of hours. The second attempt was successful after
positioning the legs through the holes and bending them gently in different
directions before resoldering.
I'm not sure that you would be able to use two clips at the same time. If
you look at the angle of the heatsink in the photo you can see that it's not
square to the motherboard and it has to be twisted even further to get the
hooks through the loops. A second clip would require the heatsink to be
twisted in the opposite direction and the first clip would seem to prevent
this or perhaps the judicious use of a pair of long nose pliers is warranted
and hope that the 'spring' isn't taken out of the clip.
However as you have much more practical experience I must bow to your
superior knowledge.
One last point, although I managed to find bios, sound and motherboard
drivers when I reinstalled the o/s none of them were needed, XP SP2 found
all the devices and supplied its own drivers.

You can see an 845PE board here (about the same generation, more or less), and
this one uses two loops to hold the Northbridge heatsink in place. For some
reason, the parts here look like they were meant for one another.

Many thanks for all the replies. Good stuff
Looks like I have 2 choices, solder in a new loop or epoxy and heat paste.
Not sure which I will go with, I'll have the mobo out and decide then.
To the guy who recommended the extra RAM: you are right the PC does only
have 256Mb. I will recommend the owner gets more!! Actually, thinking about
it, I think I have aother PC with the same RAM so I'll see if I can
demonstrate a difference.
