After I delid my 7700K, do I have to put the lid back on?

[raptor15sc]

I'm going to use a Rockit 88 tool to delid my 7700K, do I have to put the IHS (metal lid) back on after I take it off? Or can I just mount a Thermaltake Water 3.0 Ultimate 360mm cooler on the exposed die directly? 
Either way I'm going to be using Coollaboratory Liquid Ultra thermal paste. Let me know what you think.

[The Sloth]

why did you delid your cpu without not knowing this before hand. replace the thermal paste and put your cpu back the way it was. you can kill your cpu by deliding, its a stupid idea to even do such thing.

I said "I going to" by which I meant: "I'm going to." The 7700k is being shipped to me right now.

Is this your first build?

 

If so don't even think about delidding.

 

On top of that Linus has shown delidding only yields a roughly 5C performance increase. IMO it's not worth it for the risk or a destroyed $300 CPU

Probably my 11th build. Last one is in my post history.
Also, I don't think you're right:

When you delid you also void your warranty. And yes you put it back on. The point of delidding is to put on better thermal paste.

don't its stupid delidding is a stupid concept to use right now. please be smart and don't mess up your CPU. 

[phongle123]

If you're going to delid anyways, I recommend you buy a delidder tool so you don't frustrate yourself.

To all those hating on delidding, please don't speak about that which you don't know. It isn't your fault, Linus' video was basically a PSA saying don't do it , without showing why it is great. He only took it off, put some crappy thermal paste on, and replaced it. 

 

Yes, it is dangerous, and can void your warranty, but is an excellent way to get better performance if you are willing to shoulder the risk and have the ability.

 

The two good reasons to delid are if you plan on cooling the exposed die directly, or if you replace the TIM for the heat spreader with something better like liquid metal, as you can see all over the internet, using better TIM solutions and one of these methods can easily get you 10-25 degree improvements depending on which processor generation you are using.

 

So, OP, do some research, and decide which level of risk and benefit is right for you, and choose that. Both are valid options.

I was hoping someone here had already done the research...
I fear the Water 3.0 Ultimate won't sit low enough in its own mount to touch a non-lidded chip.

By all means, if you already have the tool then go ahead. You will void your warranty however.

Unfortunately I haven't used that particular chip, you can try mounting it with no CPU in the socket and see how low it goes, that'll help.

 

As for deciding for direct contact, since you're not doing LN2, I personally wouldn't. It is much riskier, as the silicon is quite fragile, and uneven pressure can really do you in. Yes, in the olden days that's how everyone mounted cooler, but more CPUs died back then too:)

 

If you get yourself some proper TIM for delidding, even if you use the heat spreader, you can still get some very noticable temp improvements. That's what I'd do if I were you.

Delidding isn't going to be worth it the 7700K already has reasonable temps under a 240mm radiator, and you're not likely to get much past 5ghz no matter how much you cool it outside of Ln2

just spend that money on faster RAM if you haven't purchased anything yet, may help in a few cases for a tiny bit more performance

[KillerGamingBro]

I recommend practicing on an old CPU before doing it on a 7700K.

It is worth it if you be very careful and understand the consequences.

You have the put the IHS back on.

You do not have to do that, look up CPUs from the 80s and 90s, they didn't even have them back then.

Or you could buy food, more/better storage, better graphics, lighting, pretty much anything more useful than faster RAM. Also other than TIM, what else you do expect OP to be spending money on? Delidding gets rid of stuff, it doesn't add more!

I know they didn't, although most people I have seen put it back on.

Don't delid your CPU. If you do so it will make it harder to resell later. 

Some people see value in a cpu that's been properly delidded so they don't have to do it themselves.

The temperature decrease is from decreasing the gap between the ihs and die by removing the adhesive around it. The stock TIM on the die is actually excellent.

The stock cooler used in the video doesn't apply much pressure which doesn't show much of the benefit from delidding. More robust mounting hardware will show the usual ~20c decrease at load that you hear from delidding. I see a similar small improvement from delidding when using a stock cooler like in Linus' video.

 

The IHS doesn't need to be placed back on but it doesn't hurt much and makes it easier to get a good mount and can protect the die from uneven pressure.

Sorry, I will reword it.

Most people I have seen put the IHS back on, so I would say that is recommended to prevent damage .

Thanks!!! Glad to see progress being made (some other chain I'm in right now is going the complete opposite direction...)

Mostly true, although depending on the CPU generation the TIM can in fact be an issue (see: Haswell before Devil's Canyon)

Part of the improvement is due to better voltage regulation and not just due to the TIM. I have my suspicions that the TIM made very little noticeable difference.

OK, well i've also seen delidded i5''s and i7's on ebay delidded for slightly less than a non-delidded CPU just because the buyer was sceptical the CPU even worked in the first place.

There are also non-delidded cpus cheaper than a delidded one. If you're buying used, prices aren't static.

 

If the buyer is skeptical, that's down to the buyer either buying from a shady place or not knowing much about cpus. If a cpu is working when you get it, it's unlikely to die. If you're buying something, there should be some sort of buyer's protection if what you're buying is defective.

Just pay Silicon Lottery the $40 to do it for you. If it gets fucked up then they will replace it.

 

To be brutally honest, simply by asking this question you have proved that you should not be delidding your CPU in the first place.

Doing a direct die mount when you are using an AIO and aren't already using a liquid metal TIM is kinda idiotic.

 

Direct die mounting in the first place is mostly something that should only be done when you are trying for hall of fame level overclocks, and if you were doing that then you wouldn't be asking the question at all (much less on this forum). Frankly it's not something that even the best overclockers in the world do for daily driver systems.

[Nena Trinity]

I would delid as a last resort to fix temps or RMA it even before that if its unbearable!

[Jernau]

If your worried about breaking your CPU buy it from silicon lottery & have them delid it (or send yours to them). You can even get a 7700k binned up to 5.2 Ghz from them for x2 the price.

 

Nothing wrong with delidding, if your aware of the risks and the op sounds like he is... especially if he's using a delidding tool. He's not taking about taking a razor blade to it. Hardest part is not getting the liquid metal in the wrong spot and that's what tape is for.

[Jernau]

To answer your actual question OP,  it depends on the motherboard. The hieght difference without the IHS is the problem and you need to make sure you MB has an adjustable mount. 

 

Also, for folks who think direct die with AIO is pointless, AIO can under some circumstances, be more effective for getting temps down as there are less components generating heat as there are in your typical custom loop. I.E. You aren't sharing hot water with 2+ GPUs.

 

OP given the feedback in this thread, you might want to ask these kind of questions on an OC forum.
