Intel Core i7-7700K Delidded, Reapplied TIM Reduces Temps By 30C

[Lionheart]

Screw you Intel stop cheaping out on TIM, I was going to get this boring predictable chip due to the high overclocking support but only if you used better TIM, my i5 will do till Zen I guess.

 

[Recon-UK]

No point to this launch anyway LMFAO.

Lazy because of TIM?? it's the same CPU as Skylake repackaged.

I have reapplied the epoxy in my delids, and I still get better thermals.

If you use better paste you'll get a benefit beyond just the gap decrease of course. I'd also guess your epoxy didn't make as large a gap as the stock application because Intel makes sure that gap is there intentionally to protect the core from hefty coolers.

 

[Ruru]

Thing is, temps might decrease but the performance is pretty much the same post delid. Maybe you will get 100 mhz more out of it, but even that won't really be noticeable.

And the lower temps lead to lower noise produced by cooling fans, higher OC isn't the only benefit of delidding.

true but you do get a quiter system with less chance of throttle...

IDK, not a big fan of delid, makes it harder to resell the chip too.

 

[DeathtoGnomes]

really now, Intel trying to showing it makes bad design and implementations just like AMD did before.

Here in Finland some people (including me) are just happy if buying a used chip and it's already delidded. Ofc if selling to a "normal user" who doesn't oc or anything, that can decrease the resell value.

Germany is the same - you just have to sell the CPU in enthusiast forums. On eBay you might end up with less money in 50% of the cases.

And that's where I buy and sell PC parts.

5.3-5.4Ghz at 1.5V and I may consider it. I see all review hit 5Ghz at just around 1.3V
Temp is not issue for me. I will delid it anyway if it can run.

I'm hoping for 5GHz too, since I didn't hit it with SB..

properly applied no paste is that bad.. to get a 30C difference its not the paste used.. its the fact that the things are poorly assembled in the first place.. poor contact between the chip and the lid relying on too much paste to fill the gap.. a dollop of paste and a dollop of glue and press together.. good enough to do the job but nowhere near as good as it could be.. some will be better than others..

My previous 2500K and 2600K hit 5Ghz at 1.5V but I feel uncomfortable at that time so I leave it at 4.5-4.8Ghz. Hope you get what you want.

Thanks. I had 2500K @ 4.8GHz 1.48V, but my MB wasn't that great, so I didn't want to kill its VRM

i need to know moar please

About 12-15C difference between stock intel paste and thermal grizzly kryonaut.

Not much more to tell. Skylake is easy with a razer blade and patience... and that's coming from a guy with a world class fucked up arm.

what do you use for glue in back the IHS ?

 

[Papahyooie]

Every CPU is made to handle a specific amount of power. It's rated by that, in fact. "K" CPUs have higher limits than "non-K" CPUs already. That added limit is how much MORE you are supposed to be able to push it (65W - 91W = nearly 50% boost). If you want more... look at a different product.


It's not crappy TIM. It is designed purposefully so that should power drawn exceed a specific value, the CPU will overheat, and then throttle, protecting itself. Yes, this does mean it might run "hotter" than it needs to, so that throttle can be triggered at the right point. Change the TIM< you change where that throttle point occurs, and thereby put yopur expensive CPU at risk. CPU cache, which actually produces the most heat, doesn't report temperatures.

I'll say, I don't pay for my hardware, so maybe that lets me see things as they are, rather than wanting more than I am supposed to get for my dollar. If you don't like it, then simply don't buy it.

I'm going to leave this topic now though, and I'll have more to say in the review.

That doesn't even make any sense... You're saying that the CPU is *meant* to heat up so that it will throttle to protect itself... when if it never hit that temp to begin with, it wouldn't *need* to throttle to protect itself. I understand that other parts of the CPU generate heat and don't report temps, but you're basically saying that pulling heat away from the chip is bad for it, Because it needs to throttle when it heats up and it won't throttle if it doesn't heat up.

Some massively circular logic happening here.

I use Permatex Ultra Black RTV.

 

[phanbuey]

I'm going to try the bare die on my 6700K today and let the pressure from the block hold the chip in socket. trying to find some standoffs to put on the pcb corners to keep it from snapping... that pcb is super thin.

 

[infrared]

@phanbuey I don't know if you'll be able to find anything similar in the states, I found a metal spacer from aquacomputer.de which works great.

Also, you might find the same issue as me.. the corners of the socket were raised and stopping the block making good contact with the cpu, you can trim them carefully with a scalpel or razor blade (being careful not to slip and cut a load of traces!, or bending a load of pins), then it works perfectly

gotta search something to glue back my processor

ooh thanks for the heads up... ill check it out.
