Couple things, first regarding some reviews on NewEgg about people running into major issues with the mounting system, the base not being flat, and it making horrible contact with the CPU. Here are the reviews:
- doesn't work out of the box: base isn't flat, mounting system is HORRIBLE. Can't aim the heatsink towards the back of the case on socket 939, the only option is up/down along the mounting clip axis.
The outer edges are not machined correctly, they are too high. When I put the tim on the cpu and placed the heat sink on, noneof the tim stuck to the heat sink, almost no contact with the cpu!
Those are from reputable sites....
Probably the best heat sink made if you modify the mounting system - but with the poorly engineered mounting system its 10 c hotter then the butterfly one. I truly think this is the best heat sink available today as far as its potential and ability to cool. Unfortunately it does not even get hot. that is the heat is not going into it, as my chip cooks. The only good thing is newegg let me return it. I bought another else where only because i hoped at (i had an order of items unavailable from newegg) the time the heat sink was dished. I suspected the mounting system - my instinct was right! It does not mount tightly, you clearly see it the cylindrical mounting posts move up and down when the board flexes, or by moving the heat sink. Does not fit flush do to poorly engineered mounting system. To fix this heat sink use rubber spacer on the bottom to force the heatsink to flatten out.
after pulling off the heat sink looking at the cpu contact surface, i observed a circle of thermal compound (tc) that was in the middle of the cooler interface. This circle was less then the size of a penny surrounded by a circle of bright clean metal (not good) surrounded by an outer circle of tc on the corners. Approxiamntely 50-60% of the surface was clean and 40- 50% had made contact with the TC. Either the heat sink is dished or it is warped? I think the spring screws may not distribute pressure evenly? cross tightened the screws - so the bottom is not flat or it did not seat properly regardless there is a problem.
Has anyone ran into these issues or seen something similar or more professional reviews? Hopefully this topic isn't TOO dead.
