I've had my cMP 4,1 dual CPU since new in 2009 but only decided to upgrade it now as a part of my "killing time during corona" project.
I purchased a duo of X5690s already de-lidded and installed them few days ago. It wasn't immediately a huge success, but "re-refitting" the heatsinks solved it mostly. My problem is that the CPU A still runs a bit hot even after re-pasting couple of times. This means I need to have more rpms in MFC than I'm comfortable with, even if my temp goals are little bit ambitious compared to maximum allowed. I know there's a considerable TDP difference between the old 2,26 GHz Nehalems and the full-fat Westmeres.
I also realise the CPU A heatsink does the Northbridge cooling. One of the NB pins was broken and while examining the other it broke off too, but I replaced them with equivalents from an old Asus motherboard. I re-pasted the NB while at it and the NB temps have been sweet ever since.
I read in an old post here that you can alternatively skip the plastic spacers used with de-lidded CPUs to better equalise the temp between CPU diode and the heatsink. Has any current user done this to any risk or effect? I'll also clean any excess silicone gunk left over from the de-lidding.
