Looking good hipro, welcome back

did anybody figured out the "crack bug" yet? After Cebit stummerwinter and me was of the opinion it is not the thermal paste and the cooler itself that makes that sound but the heatspreader and the gpu-core - any thoughts? we could hear something similar on 990X fullpot with the same issues afterwards so it might not be the paste it might be the hs and die...

Combination containers (CU+ALU) have different shrink/expansion rates between the two materials. Under extreme cooling those differences are greatly magnified, that crack or snap is friction between the two parts of the container. If you had a sound of that magnitude originating from the GPU core/IHS, you wouldn't have a working card anymore.

No definitly not - we are talking about full CU containers here. but as the hs is ALU (???) and container is CU - maybe there's your problem? do we need to build ALU containers then? Now that would be

After that "crack" the card won't run 1300 anymore (after passing 1600+ 03 GT3 &4 before), maybe 1200 when you are lucky. after warm-up and remount --> 1600+ again...I can tell you that was PITA during cebit ^^

@oanvoanc I don't think that's OT - that's one of the basics you need to know about CUII and it would be my pleasure to speak about that in public and togehter with thoose guys who maybe have the most experience with CU II. If more ppl. think this is not of major interest, ok I'll go pm then

I use Freeze and never get the crack
Although there seems to be different batches of freeze some is as dark as a pencil lead and other is nearly white.
