Yours too?! But how can there be no movement once it's all installed? The entire heatsink assembly rests on these four thumbscrews, if they move then in theory the entire aluminum metal strips and heatsink should move as well. No matter how tight I tightened the thumbscrews, the X-bracket still moved up and down. So you're saying there's more problems, the screws don't match the holes in the bracket? Geez, after spending $80 for this kit, the last thing I want to do is get the hand-drill out. Yes, I'm in Southern California heat as well, that's why I thought a better heatsink is needed. So much for that idea! I'll wait to hear back from Prolimatech, if it's a no go, I'll reluctantly put the Noctua back on, although I have to admit I'm tempted to try the Thermaltake Ultra-120 eXtreme 1366RT, with it's questionably flat-base.
Yeah, for 70$ (in US) sink, all this should not be needed. But I am forgiving type...
