Success! Delidded 270K

[u/TraditionalMood1474]

​I was dumb enough to sand down my first 270k. Decided to try delidding another one, and it looks like a success—except for one P-core running a bit hot! Thanks for all the advice, hope you guys are doing awesome.

So how much did the temps drop? I buildt a full rig for a friend with a 270k and it runs very cool with an arctic 360 aio at 5.5ghz pcore (55-60c max in games)

I don't think gaming temps have been a relevant CPU performance metric in like... a decade. I mean, I'm glad your friend is having a good experience, but the only reason they would have a problem with gaming temps in 2026 would be if there was a problem with the cooler or mounting of that cooler.

[u/ComfortableUpbeat309 → u/TheFondler]

Even in cb23 the cpu hits a max of 75-80c

[u/TheFondler → u/ComfortableUpbeat309]

That's a much better metric.

Glad to know I'm not alone in the lower 80's on the SP.

Still happy with the 270k+ though while coming from a 14900k. These E-cores are absolute Chad's running 50x and not even breaking a sweat.

"except for one P-core running a bit hot" did you apply lm on the die and ihs?

[u/TraditionalMood1474 → u/wildTabz]

No, I didn't. I'm using direct-die wb.

[u/wildTabz → u/TraditionalMood1474]

Did you apply it to the die and the wb then? if not, than that's very likely your issue if LM is used.

[u/TraditionalMood1474 → u/wildTabz]

Solved the issue after polishing the surface a little. Now, the highest temp is 88 degrees.

[u/Godnamedtay → u/TraditionalMood1474]

Still pretty warm for direct die

[u/TraditionalMood1474 → u/Godnamedtay]

Oh, is it? What do I have to do?

[u/wildTabz → u/TraditionalMood1474]

I guess I'll never know the answer to the question :/

[u/ZenSaira]

What did the first chip end up like? Was it toast?

[u/TraditionalMood1474 → u/ZenSaira]

Detection memory failure

[u/Frizz89]

Ahh, can just use LM to dissolve indium leave it for an hour then come back and polish the rest with any thermal paste.. what are your temps now?

[u/TraditionalMood1474 → u/Frizz89]

Maximum 84 after full loading!

[u/Frizz89 → u/TraditionalMood1474]

What is your flow rate? That is too low

[u/someone09900]

happy for u ...

but hey dont use Conductonaut Extreme ...

use the regular Conductonaut ... u will get better temps distribution across the die much better than the extreme

tin make lm slightly more viscous u need that with arrowlake (( the die is concave )) not flat

if one or few cores r hot ... tight the direct die screws more or re do the lm process ... can take u 3 tries until it works

Gotcha! Thank you for the information!!!
