Mounting problems on LGA2011 board

Read some people were having issues with the mount on LGA2011 boards but can't see any threads here.


Well, same issue for me. Could get three of the posts to line up but not the fourth without forcing it which I was not prepared to do.


I had to take the two brackets off and file the slots open a little, I also bent the brackets outwards slightly to splay the slotted arms further. Combination of both methods allowed me to fit it with the block a quarter turned thatn normally shown, tubes at the bottom.


Also noticed that the mouting screws crush the fin beneath them - fitted in a HAF932. No real issue I guess since it's only the tip of one fin each. I fitted my radiator using just the outmost four bolts, left the inner four out.


Finally, ended up screwing my fan bolts too far which results in them slightly deforming the shape of the fan casing, had to back the bolts off slightly to reduce pressure on the fan edges and allow them to square up again.


So far though, working fine and cool. Let's hope I'm one of the lucky ones and don't get any further trouble.


Out of interest, I assume the coolant is non conductive on the rare offchance that it should leak...?


Additionally, I assume the freezing point of the coolant is well below 0 degrees C...?

Yes, not many posts on this topic, here's a recent one:




The very small "fins" behind the fan mounting screw holes and across the radiator are just for heat dissipation, they do not contain fluid, a few bent ones make no difference in cooling.


I have seen fan frames bend or deform when tightening those screws. Most fans will do this in that situation. Unusual to see that but we usually don't attach fans with that type of screw. Time to back off on the torque...


The coolant is conductive, being primarily water with some ethylene glycol added to stop corrosion, etc. It would short out circuit boards, etc, if it touched them in the wrong way. I doubt that any liquid in this type of system is non-conducting. The amount of ethylene glycol in the fluid is not enough to significantly lower the freezing point. If 10% of the solution is ethylene glycol, the freezing point is barely -4C, and I doubt the solution in these radiators is any greater than that.


May I ask who makes your mother board, and did you happen to see any name on the socket itself, like Foxconn or Lotes? It may be helpful if we can identify a trend, if certain boards will have the issue you had, or not. Apparently all boards don't, but what the actual problem is, is completely uncertain at this time.
