I had just bought this randy dandy new water cooling custom setup.. And it came with some springs right.. well I use the springs to hold down the block and it barely makes contact with the CPU IHS not even the thermal paste sticks onto the cpu block and my temps are out the roof.. I just tried using the block mounted without the springs and it lowered me temps a whole 10c and I think its thermal connection is good now.. Is there a problem holding the block down with nuts only instead of springs?
