Intel P4 2.0 gig bent corner pin & installing CPU with big heatsink. How to install without bending.
Johnny Hallyday
months ago and started having boot problems - i.e. would not boot. I
could have taken it back to Office Depot but there was data on the
hard drive with code we did not want to let out - everything is backed
up.
I decided to buy a motherboard to see if that would solve the problem.
I found a replacement board by the same manufacturer etc. I had one
of our guys who is pretty good take it apart. He got the old MB out
and put the new one in. He then had to install the P4 on the new
board. The big heatsink is on the chip with the thermal tape. It is
usually fairly easy to seat a CPU w/o a heatsink or with the older P3
and older Pentiums. The P4's pins are super tiny and incredibly
fragile.
He said he had the clamp on the MB slot correct and was careful but
bent the pin.
The questions are:
1. Should I just take it in to a shop to fix it? $50 to 80 bucks? I
may have them check the boot problem too. Hopefully the motherboard
solved that. What is the repair or service cost per hour I should
expect? We considered taking the chip to a jeweler to fix the pin.
Still the jeweler who not know how to plug the chip in.
How do assemblers put these boxes together with these super fragile
pins?
2. Should I try to fix the pin with tweezers and magnifying glass?
3. How do you carefully and super delicately seat/install the P4 chip
into the slot with the big bulky headsink. It sure looks like if you
try to separate the heatsink and cpu with a straight razor blade
cutting the thermal tape that you will wreck the CPU.
Any guys or gal out there who do this daily have any tips?
Sorry if I am crossposting. Just trying to get some ideas. Thanks.

Well, I have never had a problem with "fragile" pins... But then, I am
always pretty careful about it.
At this point, you have two basic choices- Either chuck the chip and get a
new one or try to straighten the pin. If, while you are carefull
straightening the pin, it snaps off- then you are back to square one
getting a new chip.
Unless the pin is severely bent at a very sharp angle, it should be
possible to straighten it- carefully and slowly.
As far as the thermal tape- I do not use it. I use thermal paste only.
You should be able to carefully remove heatsink from the cpu in most
cases. Just completely clean off both surfaces and apply some thermal
paste.
In some cases however, the bond between the CPU and heatsink is quite
permanent, and you will not be able to safely seperate them.
Yet another reason why brand name machines (tier one or tier two) sux!!!

haveing someone opening up your machine and workink on it will void that
warrenty. So always check to see if you can get service from the
manufacturer first.

from my limited experience P4 have three corner pins, the forth is
missing and indexes the chip in the socket which obviously doen't have a
hole, if that makes sense.
Without sounding cynical the pins are not that delicate, much the same as
a PIII and the zero insertion sockets are easy to use. The only way i can
imagine bending a pin is to try and put the chip in the wrong way. As the
others have stated if the pin is not too bent it can be bent back with
judicious pressure. If its bent flat to the chip then thats another
story.
The chip is easy to put in place without the heatsink and thats how
thesocket is intended to be used. If its an Intel oem or retail heatsink
then it will move around on top of the chip * a lot 8 until the clamps
are used. As stated before use grease or if you have to, new tape.

When I went to insert the chip I found the pins had been bent on a row on
the edge of the chip. This was just a slight bend but enough to prevent it
from being inserted into the mother board. I placed the pins on my work
bench and then put a slight pressure on them to straighten them. I didn't
really notice a difference but it then inserted very easily. I'd try to
straighten the pin first very carefully and then just wiggle it in the slots
and it jus might plop in.

Ugh !
Been there, done that . I can straighten those S7 and the S370 pins
easy enough, but those are a swine to fix .
I would suggest :-
Make a "pin fixing tool" . Consisting of a bradawl, (sp?) with the end
cut off and a 1mm dia. hole drilled in to a depth of maybe 5mm . Or a
dead meter probe .
Obviously, earth the shaft and wear static strap , yada yada ...
I didn't do this (used ordinary needle nosed pliers) but this is how I
would fix them the next time ..

This is pretty much the procedure I always use when a modern CPU has a
bent pin, FWIW. If there is just one bent pin, I hook a fingernail over
it, with the top of my finger pointing in the direction it is bent toward,
and pull very, very gently.
The thing is, as long as you're gentle, you're going to probably make the
best of a bad deal, and that will either be that it fits, or that the leg
breaks off, in which case your chip *might* still work (look the pin up,
see if it's actually *connected* to anything [important]), or not, in
which case you buy a new one.
Bent pins generally do not fall under warranty. They certainly don't come
under the warranty of an assembled system, because they can only be bent
if the CPU is out of its socket which invalidates that, and the
manufacturer's warranty usually excludes mechanical misuse.

Actually the P4 has two pins missing in one corner.

Or trying to put the chip and heatsink back in together as one
piece, which is what it sounds like they tried to do. Which
means they probably tried to force it into a closed ZIF socket.
For the original poster:
P4 boards have a ZIF socket with a lever that has to be opened to
insert the CPU. The problem is that the lever ends up under the
heatsink, so you can't open the lever and insert the cpu and
heatsink together and then close the lever.
So the only right way to do it is to remove the processor from
the heatsink, clean up the residue left from the thermal tape or
whatever sticky compound was gluing the heatsink and cpu
together, install the CPU in the board using the lever properly,
apply new heat sink compound (use the white stuff and next time
you won't have this problem), and then reinstall the heatsink.
I've used a heat gun to soften the sticky type compounds that
glue the cpu and heatsink together, but it is tricky cause you
have to heat the heatsink without heating the bottom of the
processor too much. The pins are soldered to the bottom of the
P4, and if you let your heat gun blow on the pins too much the
solder will melt and the pins will fall over, and they you really
are screwed.

Hi,
Pen/Pencil shafts are useful for this too (with the ink/lead taken
out). Slide the shaft over the pin and then straighten. Normally no
need to go mad, just straighten enough for the chip to go into the
socket.
