Solved IHS Removal

[ben946210]

Has anyone had experience or have done this? I did this a month ago while waiting for my video card to arrive. It appears to be in perfect condition but my system appears not to POST. I tried another CPU of the same type that also had the IHS removed (and was tested working on another system) but again got nothing. I have in fact RMAd the motherboard and received another one but get the same result. I am now down to either PSU or CPU. Like I said above the IHS looks good, only one tiny nick(or more of a tiny scratch) on the die but otherwise it's perfect. Now to question: has anyone done IHS removal and had done something wrong to the CPU and got bad results? I am hoping that it is the PSU since it is still under warranty, of course the CPU is not since I did the removal.


Thanks in advance!

I would wager a guess and say it is the CPU. One microscopic nick can ruin it completely. Try to get your hands on a CPU that hasn't been tampered with to see if your stuff works.

Would the system even turn on if it was the CPU? It doesn't do anything when no CPU is in the socket so I'm thinking if it was the CPU, it wouldn't turn on. What do you think?

 

[kbrady1979]

Yes, a CPU, even a faulty one, would let the system physically turn on........but probably not much else.

Ok, another question though. If the CPU is bad, how would it know to shut off when it overheats? I don't mean to keep asking dumb questions I am just trying to understand this better until I can test another one.

If you nicked the internals of the CPU when you delidded it......it is NOT going to work right. Period.

If you tested a known good working CPU, then I would look elsewhere. Especially if the board will not even try to post. If you're getting absolutely nothng, the odds are it has problems elsewhere. Like Kelly said, that does not mean the CPU is good. It only means that you should be getting some attempt to post.

Thanks for the reply Steve,
I am hoping to get a PSU tester today to go ahead and test it, otherwise I would have to wait until Friday for my other PSU to arrive.

This topic was brought up in another thread, but I'm still curious. Knowing what the IHS is designed to do, what's the reasoning for someone to want to remove it?

With these new Sandy Bridges and Ivy Bridges, Intel got cheap and went to using a really cheap cement like paste instead of simply soldering on the IHS. So in a sense, you have to take it off if you really want to overclock which is the point of this CPU. So I guess you have to void your warranty to OC(although you technically void it by OCing anyways).

Sounds good. Let us know how it comes out. Are you getting stand by power? When you try to start the computer does anything happen? I'm sure you should get leds lighting up or fans start evenn if for only a second, even with a bad CPU. Have you tried the 'paper clip' test?

They create an enormous amount of heat compared to other CPUs. The issue seems to be that it is not the thermal paste they used, but the glue that attaches the IHS to the CPU. The glue is very thick and heavy, which causes the IHS to not make contact with the die. Therefore it is extremely difficult to remove the heat with almost any cooler. Removing the glue allows the IHS to make contact with the dye. I know of people who have done it and have experienced 35°C drop in heat at the same speed and voltage while running Prime.

The computer does turn on but it basically sits there. No beeps, no screen, nothing. It does not even get to the point of testing RAM, thats where I'm thinking its either PSU or CPU stopping it from functioning.

While I wait for the tester, I have taken some pictures so you can take a look and see what you think. I think it looks worse in the picture than it does in person. The rest is dust that kept accumulating while taking the pictures. I have the links because I think they too large to load on here.

I've never done it, so I really can't tell. But the issues is not scratching the PCB when removing the glue once taken off, and if you even touch the die when removing the IHS, it done. This guy is quite knowledgeable about it, he has done several.
