IHS Removal

ben946210 · 25 Mar 2013

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?

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).
