Well I was running a CPU intensive app (think folding but not quite) on my OC'd 4770K and now one of the cores gets way hotter under load than the rest. This only started happening after 48 hours of load with the app, not right away and didn't pop up either when I was stress testing the OC a few...
So someone (wink wink IDC) should update the wikipedia articles on IVB and Haswell with respect to the TIM/IHS gap. Right now the info is lacking for Haswell and incorrect for IVB.

You may not even be '100%' stable at stock speeds. Think about that. Stability needs a frame of reference. Is it stable for what you intend to do on it? Is it stable for every single pathway in the probability space? Is it stable with a bunch of synthetic tools that cover a large region of...
You're taking a consumer targeted tower and retention design and calling it flawed for a totally different usage scenario. Are you saying a heatpipe cooler could not easily be designed to last in the harsh scenarios that you're describing?
I mean, this is probably the same reason why using overly excessive amounts of TIM doesn't really matter. It will eventually settle to the same thickness.
I never liked the old warning of use the right amount of TIM or else you'll get horrible temps even worse than using no TIM at all. Yeah...
If the design is so good, why isn't it on the market yet? You can talk about the physics forever but a good old real world controlled test should settle things pretty well against the best of the current crop of heatpipe coolers.
This shouldn't be a problem when delidded right? With the adhesive removed, there's a constant down pressure due to the mounting mech. Even if some of the TIM gets pushed out, the down pressure should keep any air gaps from forming and the mounting mech should 'absorb' some of the added...
If you get a specific crash when OC'd and it goes away when at stock then its the OC. Thats a pretty simple way to test. No need to run a litany stress test for hours and hours. Anyone who thinks that's not worth doing to verify is an idiot and shouldn't be taken seriously.
Now thats...
Not really. There's hardly any data points for Haswell. Look at my own Haswell delid test a few posts prior. I couldn't get that low of a voltage either but I'm able to hit 4.5.
You know, I got much higher temps on my 4770K with prime95 small FFT than I did with AIDA64. You might want to try that as your temps seem pretty low under load.
I wish there weren't so many different ways to do this but with all the different mounts on the market it makes it difficult to come up with a blanket solution. I just hope our diagrams and guides will help get the word out enough that Intel stops making us do this in the first place.
