I would have replaced the pram battery while I had the motherboard out they are inexpensive and really hard to get at unless you’re replacing the cpu as you did in this video! Great video! I’m thinking about upgrading my iMac and your video showed that with care it can be done! 👍🏻

Unfortunately I’ve ruined my CPU socket while doing a CPU upgrade. So I definitely would NOT recommend to do that. The Problem are the screws and the bricks when you turn over the board (15:29). It is nearly impossible to insert and fix the 4 screws with one hand while you are holding with the other the CPU cooler. In this Video it is not shown how the guy inserted the second screw in the opposite side. They are suddenly and magically in. It is needed to use pressure on the screw that it can grip the hole. And minimum wiggle lets the CPU dance lambada on the other side without your noticing that. And when you however successfully grip and turn in the screws your pins on the socket are messed up. This was in my case so.

Hmm - this concerns me: I have to renew the thermal paste on my 1419 because it’s apparently dried out (fans max out when just browsing web pages). No choice, but thanks to your note I’m gonna be extra- super-careful(!) Any tips for keeping everything aligned when putting back together? (Or maybe what *not* to do?)

@@DaveEtchells Yeah, you can fix the CPU on the two corners with a mini drop of hot glue gun (don‘t know the exact english name for that) so that the CPU is fixed on the socket and can’t wiggle.(really a mini mini drop). As second yo can pre-bend the corners of that X typed Metal sheet a on the backside little bit, so that not max pressure is needed to fix the screws. I would also recommend to that with two persons one is holding everything stable the other is trying to put the screws in. Good Luck.

@@pokololo50 Ah, great suggestion about the hot glue! I will have to be careful to use just tiny amounts of it though, so it won’t interfere with the pressure needed to hold the CPU against its contacts. Also a *great* idea to have two people: I could hold it in place and push down the tabs one by one, while my wife gets the screws started. Thanks so much for the suggestions! (Hmm, bending the tabs down to reduce the pressure would work too, but once it’s all together, you want a lot of pressure to squeeze the thermal paste as thin as possible. I wouldn’t want to bend them back and forth too much, but it might be possible to flatten them to get the screws in place, then one by one with the other 3 screws tightened down, bend each one back up to its original position and replace and re-tighten the screw.) It’s bad that the video doesn’t make a point of this. 🙁

@@DaveEtchells In my case after I had replaced the Board I‘ve exactly done these two things (glue the CPU with socket and pre bend minimal this X Formed metal sheet on the Backside of the CPU). For me it worked well. But of course you can try without bending that plate but here is the recommendation, if you anyhow notice that screws won’t grip then do not to try with violence to put anyhow the screws in. Better is stop at that point check and then try again. Don’t be afraid. If you are very careful then it should be ok. I also agree. They could give a couple of more hints about these screws in this video. It looks very easy but it isn’t.

@@pokololo50 Thanks for your advice: I think I was successful. - I say I think because I haven’t tried booting it yet. (It’s going to be a process, because I swapped out the SSD, so have to do a bare-metal MacOS install and it’s very late here tonight so I’m going to tackle it tomorrow.) The actual heat sink reattachment ended up not being too bad. (Documenting here so someone else can hopefully find it at some point) I did tack the CPU down with some tiny (really tiny) dabs of hot glue in the corners. Then I screwed down the GPU heat sink first, which helped secure the CPU side. Next I put a screw in one side of the spring bracket, turning it only enough to insure that it was fully engaging the heat sink threads. (I only inserted one screw then worked on getting a screw into the opposite corner of the bracket, but think it would actually have been perfectly fine to just-barely put a screw in the other hole on the same side too.) With the heat sink pretty well immobilized at that point, it wasn’t hard to push one arm of the other side of the spring with a finger while I put in a screw to hold it, again just turning it enough to make sure it was fully engaged with the HS threads. From that point it was easy to do the same with all the screws for the spring, pressing each arm of the spring down with a finger while I tightened its screw. I actually did this last night and today has been a looong day so my memory is slightly fuzzy as to whether I actually managed to get the fingers of my hand around to the other side so I was “pinching” the spring or if I was just careful not to press the heat sink assembly too hard against the bench, so just a note to others to be careful when pressing down the arms of the spring with your fingers not to damage anything on the other side by putting too much force against whatever it’s sitting on. In any case, the spring bracket ended up being much less trouble than I expected it to me - thanks in large part to your suggestion of using tiny (emphasis on “tiny” to others reading this) blobs of hot glue to keep the CPU from moving around. Thanks so much for your advice! (To others reading this, I didn’t apply the glue directly with my hot glue gun. I squeezed a blob out onto a piece of cardstock, then used a heated, small-bladed flat screwdriver to pick up bits of glue and transfer it to the corners of the chip/socket.) (Update: This worked great; the fans only spin up under high workload, and almost never get to full speed like they used to. It was a bit tricky but worked well AMs was very worth the effort 😁)

Absolutely untrue. The cpu retention method is extremely risky since the cpu is held down by the heatpipe and when you unscrew the cooler, the risk of a socket pin bending is real and very easy to accidentally do. I bricked my imac the other day and I've been building pc's since 1998.

@bitshuffle
@bitshuffle Жыл бұрын
The strongest cpu you can put into your computer would be the i7 7700k, since there is no core i9 for 7th gen intel processors. The 7700k though is well known for being a hot pocket, so maybe look for good thermal paste if you plan to upgrade to the i7. The i7 7700 non K is slightly worse and slightly less hot. Might be an idea too.

Buy a mixed pack of thermal pads - I think mine has 0.5, 1, 1.5 and 2mm - and use that to match up to the pads you remove. (I may have added the 2mm pads to the set separately.) It’s easy enough to see if a pad is compressed or not - if there’s an uncompressed edge then match the pad thickness to that, if the whole pad is compressed then go 0.5 or 1mm thicker than the compressed thickness.
