Yes, it can move a bit. As long as you followed exactly the install insructions and your sure all the 4 push pins (not sure if it has push pins) are fully secure you should be fine. Yes, they do twist a bit if you want it to.
So you meant the heatsink, a little movement is normal Conumdrum said but it will seat as you use it and the thermal paste will bond to it. Just go into your BIOS and make sure your temps are fine at idle.
Contact Gary Stofer at Sidewinder Computers
to ask when he will be stocking the new
"LGA1156 bolt-thru-kit". Last week, he told
me his company is already evaluating a
working version, so he should have the
new bolt-thru-kit very soon.
