they won't delid and leave it naked, their delidding service has to be re-lidded.

at least that was their response to me a year ago when I asked.

If they relid the CPU what's the point in offering a delidding service at all?

Hi,
They use liquid metal not solder or thermal paste is the point.
They just take the risk away from the user to delid.

Do it yourself if you see no point in LM and want to use direct die frame.

Hi,
Silicon lottery sealant is a lot easier to open up than braking a soldered chip apart
All you need is a couple razor blades

I dunno, I asked for a quote for them to do mine and they said they didn't offer that service and when I asked why they never got back to me.

I'd imagine it's to limit liability either by the customer damaging the die themselves and claiming SL caused the damage or by the shipping company doing the same in transport.

Replacing the solder with liquid metal does get a tiny gain though.

I’ve delidded 4 9900k and all of them produced a 8c to 10c drop it temps with a copper ihs. Has anyone has better results with stock ihs. I think it has to be sanded down to fit again properly but I’ve never had the patience. Tried direct die with the Der8auer Intel 9th Gen OC Frame and my cpu got damaged from to much pressure wouldn’t try that again.

Because they can't ship the CPU without it being resealed.
If the chip box gets dropped around and thrown around like a basketball by some college kid working at Amazon or UPS, that liquid metal is going to get all over the place, and if any gets on the back MLCC caps, that chip is history. They don't reseal it with a thick sealent because they want to. They reseal it because they have to, even if a floating IHS sealed with a Kryonaut edge layer as a sealant to stop the IHS from moving when you mount it (yes, this does work) gives the best temps.

I was thinking a direct die to my noctua DH-15s. It's interesting that the description of the delidding service on Silicon L. doesn't mention they'll re-seal or use liquid metal between the IHS and die.

I vaguely remember a discussion about the delidding service that Silicon L. offers and that someone wanted them to use a Cu IHS instead of the stock Al one but Silicon L. turned him down.

I would just use the rocket kit with the solder remover if I where you, if your thinking about reusing the his IHS I believe it has to have a mm taken off so
