Ivy Bridge IHS

[N0b0dy]

Hello everyone,

yesterday i decided to replace the thermal paste of my i5-3570k. I removed the head spreader and removed the old thermal paste. I did it exactly like in the Video here Fixing Ivy Bridge CPU temps: IHS removal - YouTube. The thing is that my PC starts but then it shuts down and restarts all the time. I can't do anything
I also thought that my motherboard was broken because some of the pins were bent.
Can someone help me to find which thing is broken ?

Well for an expensive i5 my friend that is something absolutely crazy to do it seems to me that whatever you reapplied inside that CPU is not working as it should be.

It's pretty obvious to me and I am no expert that the cores are overheating like crazy and you might have to repeat the process and hope it hasn't wrecked the chips.

If it were me I would do that and make sure the surfaces are absolutely and perfectly clean and prepared before reapplying the thermal - inside and out side.

I use the Arctic cleaning kit and then Arctis Silver 5 compound but I have never done the inside of a CPU to be honest.

Arctic Silver Incorporated - ArctiClean & Arctic Silver Incorporated - Céramique 2

though I have had some good results with the Noctua NT-H1 compound it is slightly thicker and harder to spread but good. http://www.noctua.at/main.php?show=productview&products_id=13&lng=en

Plus I do hope you haven't bent any of the pins in the socket

That was very interesting. I have no idea how one fixes bent pins on a motherboard. I do think that if some one had drastic temps between cores that would be a good thing to try if you are out of time for a RMA. I will try that some time when I don't mind messing up a $300.00 CPU that is working just fine.

I thought you were a proponent of "if it ain't broke, don't fix it!" One fixes pins on a CPU socket the same way porcupines make love...very carefully.

All seriousness aside, I wouldn't suggest messing with delidding a CPU unless it was running insanely hot and was out of warranty. At that point, you have nothing to lose and everything to gain. I will admit, watching that guy working with that razor blade then watching the heat spreader squirming around while latching the chip down made me as nervous as a long tailed cat in a room full of rocking chairs. I could just see himself cutting his fingers with the razor blade or bending pins while chasing that heat spreader around.

Basically what I have said and for what it is worth if the CPU was running that hot it should have been a RTM job.

Having said that it is possible to straighten the socket pins - on the proviso that they are not that bent using a piece of old credit card cut to the exact width (dimensions) of the socket recess and placing it between the pins and gently bringing them back into alignment by sliding it very carefully from one end of the row of pins to the other until the card is behind the complete row of pins and then begin the process of bending them straight again. You sometimes need a second piece of card to gently force the bent pins onto the first inserted piece of card.

However the pins as I mentioned should not be bent more then a few degrees out of perfect upright alignment say more than 10-15 degrees otherwise if they are really flattened the chance of successfully getting them all aligned again is slim and runs the risk of actually snapping them.

Before anyone poo pos this I have done this on a few occasions with both the 775 pinned CPUs and the LGA sockets. It just takes great care and more than that patience.

As I stated I thought quite cleverly if a cpu is out of RMA and I don't mind messing with a $300.00 cpu I would try it if the temp were way out.
The video showed temps in the high 90c. He also stated he hit 100c.
If normal methods of proper cooling didn't work I would try it before buying another cpu.
This statement I guess says it all.
I will try that some time when I don't mind messing up a $300.00 CPU that is working just fine.
Well that time isn't going to come; I hope.
If I'm unlucky and that time did come and RMA wasn't a option I most certainly would try it. Nothing to loose. I don't think the compound was the problem. I think it was the black goop around the top plate being to thick holding the plate to high off the chip. He left the black goop off so the chip could settle in place. If the problem was the compound and goop not allowing the little metal plate to make good contact with the chip it should of been that way from the start. Which means overheating from the start (first use). Which means someone should of RMA the chip from the start.
I have 3 computers with zero cpu overheating so I don't do such things.

 

[ICIT2LOL]

I agree Layback and for what it is worth I wonder how long that temp problem had been going for?
I have eight machines to hand and like you have not had any temp problems with any CPU's I have installed.

At the very least if there were such a problem it just goes to show that even Intel are not infallible, and that one should not rely on the fact that is an expensive item that one automatically assumes that it is good.

Personally I think that you have hit the nail on the head saying that the compound both inside that enclosure and the adhesive holding the heat spreader were not in sufficient quantities or assembled correctly.

But I still wonder at the advisability of deconstruction of a device in that manner. Not only could it destroy the device but was certainly a very risky handling operation - one we see in the emergency room on too many occasions through sheer stupidity.

RANT ALERT!

RMA is a noun, not a verb, and are the initials for Return Material Authorization. I worked 30 years in warehousing, including shipping and receiving. When we returned material it was called a return by us and industry. The period of time that a manufacturer would replace or repair a product that failed due to a defect was called the warranty. All RMA meant was the authorization from the manufacturer or vendor to return the material and consisted of either a document from the manufacturer or vendor and/or a number supplied by the manufacturer or vendor and would tell the receipient of the return why it was being returned. Never, ever did I hear RMA being used as a verb to define returning material nor did I hear it used to define a warranty except on computer related websites.

Rant over. You are being returned to your regularly scheduled thread.

I think he knew, or should have known, the risks before the delidding. Some people decide to take that risk. Some have achieved excellent results by doing so. Others have ruined the CPU also. It's a gamble. However, I think the answer to his question is, you have to fix one of the issues before finding out which one it is. The behavior he described sounds more like the CPU pins. That is common with bent pins. Yes, you can straighten them yourself, but if the same problem occurs, you will not know if you straightened them correctly or if it is the CPU. My suggestion would be to call Gigabyte and see about repairing the bent pins. Yes, they will charge you for it, but it is the only way you will know, short of buying a new board or CPU.

Thanks for the replies.
I already contacted Gigabyte and i'm waiting to get my RMA number. So back to the topic. How do i know if my Motherboard or my CPU is broken ? I've also seen several people having the same issue with the Gigabyte Z77-D3H. They're also stuck in a boot loop.
The reason why i did this was that my CPU was running about 95-100c. Do i have the chance to get a new CPU from Intel ? I'm still under warranty.

BTW i'm using the Arctic Silver 5 between the head spreader and the die.

 

[Lady Fitzgerald]

You probably blew the warranty on the CPU when you delidded it.

 

[Layback Bear]

If one returns a product for a free repair or replacement under warranty is their a proper acronym that should be used instead of RMA? One that the folks reading our post would understand without Googling. I would gladly use it.
---
I will try to be more precises. Hope this helps N0b0dy.
1. A overheating problem like NObODy has stated would of showed up when the cpu was first used if assembling of the cpu was the problem.
2. If there is a cpu overheating problem I would make sure all the normal procedures were take first. (check you bios for updates relating this problem)
2.a Checking temps with a few different programs.
2.b Replacing the cpu compound using Arctic Silvers methods. While that deep into you system check for damaged pins. Damaged pins will give false readings along with many other problems.
2.c Installing a high performance cpu cooler.
2.d Make sure the proper harness/cable routing is correct for proper air flow through the case.
2.e If it was a new case I was unfamiliar with I would make sure the amount and orentation of the fans were proper. If all this fails to solve the problem.
3. If your motherboard and or cpu are under warranty I would recommend using the warranty and wait for your RMA report. If the RMA report is not to your liking I would take the steps in the video. Of course you will have to be very careful with the sharp object you select to use.
4. Please read Step #1 again.
---
If all the above are done and you have no other options I would try it.
You have nothing to loose but a finger or two and some blood if proper safety methods aren't used.
P/S: Please read Step #1 and #4 again.

What's wrong with just calling a return a return? It worked just fine for everyone most of my life. Btw, RMA is not an acronym. An acronym is the first letters of the words of a phrase used to to make a pronounceable word. Example, PITA is an acronym for Pain In The ***. RMA is unpronouncable unless one has a really limber lip.

Little comfort...but before delidding (which I would never do) did you go through the normal procedure of reapplying thermal paste to a clean CPU/heat sink surface. If the unit was still hitting these temps (not overclocked) even with a stock CPU cooler it would have been a clear warranty claim.
Unfortunately I think you've voided your CPU warranty and need a new motherboard.

 

[N0b0dy]

I did the normal procedure. My CPU was about 45-57c on idle. Not overclocked with stock cooling.

 

[N0b0dy]

So what are the signs of a broken CPU or Motherboard ?

 

[mjf]

I did the normal procedure. My CPU was about 45-57c on idle. Not overclocked with stock cooling.

I built a system recently as a gift so I don't recall the exact temps. It was using an i5-3470 and idled well below those temps. But I had a well ventilated Antec case and I'm guessing the ambient temp was ~25C.
Your case has one exhaust fan I think. Adding one or two optional fans would have helped.
Then after meticulously reseating the cooler if I was getting a 50+c idle temp I'd probably try to return the CPU. But since you've "lifted the lid" I don't think you can expect to return the CPU.
I don't know what others think???

 

[N0b0dy]

I've read a article about the Ivy Bridge chips. All chips have cheap thermal paste between the heat spreader and the die. Maybe when i glue the head spreader back on, Intel will replace the broken CPU ? (if the CPU is broken)

 

[Layback Bear]

You are correct RMA is not a acronym and is very difficult to pronounce. That is why a proper acronym would be handy. RMA is hard to pronounce but very easy to type and most everybody know what is being meant when one uses it. Well that is enough English 101 for me.

 

[kbrady1979]

RMA is generally just said "R" "M" "A"........I don't know why this matters at all. If you have taken the top portion off the CPU, don't expect Intel to do anything about it.
