Can someone explain all this talk on thermal grease? I've read a lot of this thread, but it isn't entirely clear to me.
From what I understand, you are taking off the heat sinks, adding thermal grease, and then putting them back. Why do you have to do this? It seems it makes it cooler - does that make them hash faster? Which heat sinks do you replace? Is this a problem only with Batch 1-3 or something, or would you recommend this for all of them?
Taking off the heat sink and removing the absurd amount of paste on the chips. Why? I had issues with units not starting and having X's on the chips. Replacing the paste will make them hash better ( a few GH/s) and maybe a little cooler (1-5C). You are not replacing the heat sink itself, just the paste between it and the top of the chips.
