Question about CPU delidding

post #1 of 10
Thread Starter 
I am gonna try this soon once my new Liquid Ultra arrives but I have a question, after I remove the lid of the CPU, how much LCU do I need to put on the actual CPU? Would it have any thermal paste on it from the factory or just pupt LCU right away?

Do I need to cover it completely the same way as I would cover the actual/entire CPU?

one more question, after removing the IHS, how to remove the glue? I don't think a cotton swap with alcohol would do the job would it? I saw in a video that they advice not to use anything sharp otherwise you might damage the CPU

I just remembered I have Arti Clean (they come in 2 bottles, 1 and 2), is that stuff safe to apply on the PCB then scrape it off with a credit card?

A very thin layer of CLU needs to be applied.

Use rubbing alcohol or your Arti Clean to remove the old thermal paste and a credit card to remove the old glue.

See "The Hawaiian Heat Wave" build in sig for a complete guide on delliding and applying the CLU.

thanks man, so the Arti Clean is not safe to put on the PCB? only use a credit card on the PCB to clean off the glue?

I put a thin layer of CLU on the die and did the same on the underside of the IHS where it contacts the die.

A credit card works well to take off the silicone glue around the rim.

Just look at my picture should look like that

amazing video man! very clear and detailed

Here is the video if anyone else wants to learn about this:

The reason I want to delid my 6700K is because in my Eurocom Sky X9 laptop, it has the 6700K and desktop class GTX 980. I applied CLU on the CPU and even though the temps on idle are only 39C, if I overclock more than 4.2 GHz on all cores, let's say 4.4 GHz on all cores, the temp reaches 100C almost instantly in AIDA64 stability test. this is using adaptive voltage with a -150mV offset for both the core/ring as the default voltage is way too high

Here are my settings if anyone can recommend anything please feel free to do so:

BTW guys, in all the videos I've seen, after removing the IHS, they remove the glue that was used to stick the IHS to the PCB. But is that really mandatory? like what if I don't remove the glue and I don't intend to actually stick the IHS back, just want to place it on the CPU and lock the CPU in place in my laptop......

Let me give you some practical tips on applying CLU since I've delid a few chips myself.

First of all CLU is pretty agressive stuff and it also conducts electricity. So be very careful when applying.
Apply it when you chip is out of your laptop, not inside your socket. You don't want to accidentally spill anything on vital parts (motherboard etc).

Now back to the CLU. This is, as I said, not your ordinary thermal paste. Its like liquid metal.
On the IHS you can put a really, REALLY tiny drop of CLU. And when I mean tiny, it has to be about 1/5th of what you normally put on a CPU heatshrink (pea method).
The little brush is used to cover the whole surface and CLU spreads out quite annoying at its liquid metal. I really cannot stress enough on how little you should use, you will probably still end up using too much.

Now as for the brush that CLU includes: it's too long and a lot of CLU will be lost inside it.
A practical tip is here to cut off 50% of the brush with scissors; please do this, it will save a lot of otherwise wasted CLU that is stuck between your brush!

Alright moving on to the delid and mounting.
I would remove the glue for one simple reason: You want your chip to be as clean as possible, any residue can negatively impact your temperatures. The glue can attract heat or cause the external heatsink to not be mounted 100% flat. It's fairly simple to remove most of the glue with just some rubbing alcohol, a micro fibre cloth or even a creditcard. It doesn't have to be 100% gone, just get most glue residu off.

You can just mount your CPU with a non-glued heatspreader on top of it, just make sure it doesnt move or slide out of position when mounting.
You can also do a bare-die mount ('naked mount') but I'm not quite sure how this works on a laptop in terms of enough heatsink pressure, mounting issues etc.
