Coffee lake delid questions

Planning to delid my 8700k when it arrives.

I've read you should cover the contacts under the heat sink with nail varnish but from what I can see the die is pretty far from those little gold contacts on coffee lake, so how important is it to cover them?

Also what nail varnish do you use and how much do you apply?

Regards
 
I just delidded my 4790k and used conductonaut never bothered with nail varnish but i didn't squeeze the syringe straight on to the cpu you need so little of the stuff.
 
Never used nail varnish on any I've done myself just don't put massive amounts on chip , try on a scrap of card or paper to gauge the pressure you apply on syringe and the flow etc , you don't need a massive amount.

Don't delid without testing the chip first to make sure its ok
 
I always varnish mine but I used to use liquid metal. If your just using a good tim your fine not to bother with the varnish

The idea is the varnish stops the liquid metal from shorting out and contacks. But normal Tim is not none conductive
 
I used conductonaut on all of mine but if your careful when applying it and don't put a massive amount on I don't see the need for varnish, but if you have some to hand there's no harm using it you can use normal tim under the heat spreader I tried mx4 and some nano gel and whilst they helped with temps compared to the crap intel used if your going to delid may as well get the most out of it by using conductonaut.
 
How did you guys get the heatspreader off? With a razor I'm guessing? Will be doing this with mine as soon as I get it (after testing).

Or you can use a vice. Seems the riskiest method though.


Or just save yourself the risk and get a delid tool. You can 3d print your own if thats an option

Don't use a vice on the newer cpus as the older cpus where a lot thicker . vice was ok on ivybridge but on skylake onwards would probably snap it in half
 
Get a der8auer delid mate 2 and the lid will be off in 5 seconds without damaging the pcb. It's also got a guide plate for resealing the IHS back on. Better spending 50 quid or whatever they go for now than killing a chip! Can also so your mates chips whilst your at it. :)
 
I looked at getting a der8auer delid mate ages ago but where can you find them in stock, if you're careful with a blade you wont damage the pcb
 
Stanley blade.

If you do the vice, you need the die to run front to back in line with the vice. If it side ways the die as been known to come off....
 
get a delid die mate 2 or a dr delid, both look really safe compared to all the murdered chips ive seen done via knife and vice - diemate 2can be bought from caseking.de for around £40 with shipping
 
Rather than nail varnish, you need to be careful and use the correct one. I'm planning to use Heat Resistant Tape on my SKL-X CPU.

In terms of de-lid tools, you have the choice of the Die-Mate2, Rockit 88, Aqua Computer tools then you have other methods which I'm not sure id be brave enough to use.
 
gents. The coffeelakes are thinner than the skylakes or haswels. using vices, knives etc you could break them.

use proper tools or buy delided/binned one.

as for the liquid metal appliance, use tape to cover the sides around the die and IHS. No need for varnish..

Google search kabylake delid videos, not ones from past years.

There is a risk even with proper tools , i'd rather take my chances with a 50 pence blade then pay 50 pound for a delid mate if I was doing a lot maybe it would be worth it. you could get a 3d printed one that you would probably have to modify to get the cpu to fit or like you mentioned binned and delidded which carry a premium of one or two hundred pounds upwards more then retail.

I assume you take the tape off before fitting the cpu , the varnish is more to protect for seepage caused by too much liquid metal being applied etc once fitted

Did that before I delided my first cpu and a third of the results shown someone using a blade and not a proper tool .

yes you remove the tapes.
 
I sit the IHS on a iron for 10sec then I do the delid with a Stanley blade. I have done about 10 and all have been a 30sec job. I did a 4790k last night

But as others have said clock the CPU first. Then use it a little and see what your temps are
