CPU overheating problem

John you could also use some epoxy around the inserts and let it cure before taking the screws out. I'd not try jamming a screwdriver tip in there and risk wrecking the board if it slips.

Yes mate I am not looking forward to it to be honest - pig of a job any way you look at it.

Those screws doing that could of been caused by the screws bottoming out in the nut before tension was put on the cooler mounting plate.

Because of this the cooler was not tight against the cpu but the screws were tight against the nut. (Thread depth of the screws)

This could also cause uneven pressure on the pump mounting causing the noise. (Impeller hitting the housing)

Sorry Jack I missed the post now seeing your post makes a bit of sense it certainly would explain the lack of cooling!!
Now there were two sets of screws that came with the Intel perhaps I used the wrong ones?? Mind you it seems very bad luck that the problem with the OS crash and this coinciding.

Up to now I have noticed a gradual increase in temps as on build (Nov 2012) the temps were around 26C and for the last three to four months have risen to 45C and spiking to 50C.

The instruction sheets are often too small to see illustrations. Other screws may be for socket LGA2011.

Yes Gary I think you are probably right if I remember rightly they looked almost identical in the small package they were in and I was stupidly thinking they were putting them in as spares

Anyway I am contemplating going back to air cooling too as there are many questions and concerns re the LC especially the rad that I cannot find answers for.

For example and being in danger of becoming boring - why have a core when the IN connection is in the same "tank" as the OUT it simply make no sense to me that the coolant has no apparent way of circulating through the main core which is supposedly what is supposed to happen to get the maximum cooling effect.

I would really like to know where to look now as it is going to bug me until I find out

Yes Kelly except that as I said previously the temps were creeping up as at build I was getting on average 24C but just before this crash I was on 45C.

I have no explanation for this except that perhaps the hold down screws were not tight enough to hold down the cooler plate onto the heat sink. Over time perhaps this has allowed the compound to get thinner or leak out - it certainly was down the side of the heat sink when I first took the cooler plate / pump off. That would then have made the contact uneven at best and insufficient at worst.
