Ivy Bridge IHS

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=p...s_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.

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.

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.

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.
