Only nut and bolt I can fin dis a 4-40/ 1 inch will this work if I add the springs or will it be an issue?

Good deal had a brain fart totally forgot about the clipping of the extra.

Thank you

What you can do is use one of the
heat sink pins that you've removed
to mark the length on the replacement
bolts. That way you'll know how far
down the the length of the bolt to
tighten the nut. You'll get the correct
length that supplies the correct spring
pressure. Longer bolts are much easier
to manipulate if your reinstalling the
springs. Then just snip off the excess
from the bolt. The problem for most
people is finding the correct bolt length.
Its fairly easy to find 1/2" which will work
without springs, 3/4" is the correct length
and bolts that are longer make it much
easier to reinstall with springs. If you've
found them 3/4" or longer you should
post a link for others.

Well, upgrade went very smooth. for anyone looking for a great deal there is a guy that has 2 T7200s left he only wants $30.00 shipped for them. PM for more details.

What is the fastest CPU you can put in an old mac mini 1.1 (September 2006)

I've found a cheap T9600 (2.8GHz).
Will it be possible to mount?

[Smithcraft]

You can use the T7200, T7400, or the T7600.

Make sure it has pins!

It might be mentioned somewhere in this post, but there is a great tutorial here on doing that processor replacement as well as on ifixit. Might want to consider getting yourself some nylon nuts and screws to use as a replacement for the heat sink pins that you will probably break when doing this. They can be found on eBay for just a couple of $$$.

Good luck!!!

The story: Having gotten my hands on a T7400/2.16 out of an iMac 24", I just went through all the processor (and more) upgrades -- and thought myself clever for getting the nylon fasteners out of the heatsink without breaking the hooks.

But when it came time to put them back in, one managed to snap off at the tip, dagnabbit.

So like many of you, I was stuck without a way to get the heatsink back on-- and dutifully went out to my local big-box hardware place, with the hope they had the right size to fit. The smallest nylon screws available now at both Lowes, Home Depot and Ace are 6/32 -- which is just a touch too big.

I read about the #4-40 size (as mentioned here and other sites), and called around to find somewhere that carried the nylon screws. No luck. You can't even get these at RC hobby shops like HobbyTown any longer. After a couple of days of searching, was ready to pull the trigger on the eBay auction.

Then I stumbled across a specialty fastener company in town-- only a couple of miles from my house-- that had the nylon 1" screws in round ("pan") head with bolts and washers.

But because they had a per-line minimum charge, I had to buy more than just 4 -- I ended up with 40 of them!

So if anyone is needing some, I can sell 'em a set at less than the eBay price - $2.50, plus shipping. I've got 8 sets of four screws/bolts/washers left.

Drop me a PM, to work out the deets -- or email my username at gmail.

When replacing mine, I put the screw head side down (under the motherboard) with the bolt in the heatsink. This way, you don't have to cut the screws, and the thermal pad makes contact with the chipset properly. Also, I used the washer on all but one of the holes, because one diode would have been under it. Don't think it would hurt, but didn't want to put extra pressure on it, in case the solder developed micro-fractures.

So far, the processor cores are idling at about 45 degrees C. That's actually a bit higher than it used to be, as I also upgraded the memory.
