Wait a minute. 30c drop in temps? Are you running it naked?
Also, sub'd.
Yeah 30c is a pretty typical temp drop on IVY after delid if you do it correctly/got one of the ones they did a really shabby job on the IHS application of.
That glue is seriously annoying, my die wasn't even making contact at all with the IHS.
I'm using CLU on the DIE, Coollaboratory Ultra, it's like a liquid metal TIM best you can use for between DIE and IHS.
Comes with mini paint brushes as well, so you just put a tiny tab on the die then brushstroke the die till covered nicely.
The on the bottom of the IHS where it should make contact with the die, you put a thin layer in the form of the DIE.
No I'm not running it naked, I've reapplied the IHS unlapped as well.
Thanks for the sub!
