Delid/Lapping/Sanding IHS 6600k help/advice/tips please :)

[DJ1203]

Hi all,

Never built with intel before but am throwing together a cheap and cheerful PC for no reason other than a bit of fun.
I will be running a 6600k, and want to see how close to 5ghz i can take it (on Air) so naturally the first thing i'm going to do is sand the IHS as flat as poss, delid it, and replace TIM with Conductonaught LM.

I have a couple questions as i have seen this done in numerous ways...

Lap the stock IHS, or buy a Copper flat (supposedly) IHS from ebay etc?

Is it better to use LM on both the Die and the inside of the IHS? Or just on the Die?

Is it better to re glue the IHS (was going to use a drop of flexible glue on each corner) or to leave it free floating? Or is that a bad idea due to the LM and better for using paste?

Many thanks in advance!

if you are doing this for a bit of fun, i would:

Lap the CPU yourself. Cheaper than buying a copper ihs.. otherwise if you intend to sell the chip at some point, buy a copper flat as lapping the CPU would remove the characters on the IHS itself.. possibly making the selling of the chip harder

If you are putting the IHS back on the CPU, then from what i've seen many people do -
LM on die. Kryonaught on IHS

If you are running Die only, then LM on Die with an appropriate bracket/naked ivy mount so you don't end up crushing the CPU when mounting the cooler

If you do put LM on Die and inside of IHS.. make sure its a super thin layer so it doesn't spread to contacts. You can use heat resistant clear nail varnish on the contacts if you are worried

I've heard its not good resealing the IHS, but i'm sure others can comment on that.

I’d build the system first as the chip will probably tap out before you run into overheating issues.

I'm not so sure. Skylake generally drops 20c with delidding and liquid metal. That let me push the OC on my 6700k another 200Mhz. It's definitely got more headroom in it, I just don't want to up the volts past 1.39v.
