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.
This is correct. The H110 doesn't work the same as the H100. Also, I'm not really losing anything from spacing the backplate as the H110 backplate is made of super flexible plastic so its not really adding any rigidity even when up against the motherboard. I still have the CPU plate though...
As promised:
You would think it would be easier to put the offset washers under the springs but in the case of the current gen Corsair waterblocks, the spring post is oddly shaped and not very easy to find washers that would fit.
Razor is fine, just be careful. I got 99% of the adhesive off with a razor at a very very shallow angle with moderate down pressure. Didn't catch on the PCB at all. Smooth as silk. The rest I got rid of with IPA and swabs but you really don't need to get it 100% clean unless you feel like...
Whats the point of SSD raid with top shelf SSDs? You're not going to improve random access times, only sequential speed. What good is going from 500Mb/s to 1000Mb/s? Will anyone even notice that?
Sadly I really don't care about lifespan. Not on this chip anyway. Once I get a hold of something that OCs a bit better, then I'll hold onto that.
I must sound like a bad parent given its fathers day :\
I don't know what the distribution of popular methods are but IDC wrote a good guide on springless mounting in this thread.
Im personally using H110 stock mount which uses springs in conjunction with 3mm worth of nylon washers to offset the loss of the IHS (~2.5mm). So technically I have 0.5mm...
Well, unlike your H100, mine was pretty uniformly convex in the center. Maybe even deliberately so since most of the current Intel IHSs are concave.
Mine had radial machine marks which would imply that it was possible to machine it convex deliberately.
Well, I went a totally new direction. Bought a H110 and went direct die with a 4770K. Results were lackluster at best. 5-10C drop. Then I decided to pop off the H110 waterblock and put a razor on it. Sure enough the damn thing is extremely convex. *sigh*.
Didn't really plan on lapping but...
I'm actually leaning towards just buying this:
$5
and this:
$5
Hopefully the springs will let me fudge exact tolerances and I can always throw some washers in to get the right tension and depth.
This thread needs a bump for Haswell. I'm not sure if I want to do the IDC 'Home Depot' mount or buy $10 worth of replacement mounting hardware for the XS-PC block to retrofit on a H100.
Edit: Ok I'm going through some ideas.
1)Use a M4/M3 10mm standoff and a few thin washers. By my math...
Indirectly from Xtremesystems and not very scientific.
Supposedly thats on an Antec Kuhler H2O 620 closed loop cooler (120mm x 1). No idea if its direct die and what TIM is being used but you can bet its top shelf and more likely direct die.
Quick take aways
1)Haswell is still hotter than...
Hey Lonbjerg, a few of us are perplexed as to why your Titan is being tied and even losing to a 470 and 660Ti respectively. Can you re-run the tests and take note of CPU utilization and GPU utilization? Just curious if the Titan is being held back by the CPU potentially.
Edit: Page 2 colorful...
Thanks! But I think your results might be slightly fast because you chose 'Photo - Detailed' and not 'Photo - Extra Detailed'. I tested the difference between them and it was ~10%. I will pad your results by 10% unless you want to run it again at the correct setting.
Yeah I garnered that much. Thing is, this will be for work but I'm testing on personal hardware since nothing has been green lit at work yet but I wanted to show some data and get some extra brownie points.
Once things kick off at work, the CPUs will have to be Xeons as the only machines we...
And yet its still doing much better with Nvidia GPUs vs AMD.
Here's all the data I've collected since starting this thread on this forum and another:
