    Looking to upgrade a MacPro 4.1

    Currently 2x2.26 quads

    Looking to up to 12 core

    Looking for someone reliable in the UK that either supplies and fits the CPUs or on a fit only basis

    Prefer in Midlands but consider anywhere in UK

    If anyone could recommend I would be most grateful

    Delidding is entirely unnecessary, the washer method works fine, all you need are a few washers and a thermal pad. A little googling should get you on track for the sizes.

    Too bad you aren't in the states or I'd mail you some thermal pad material. I have a crap ton left over from swapping cpus on cMPs.

    You do not need de-lidding. But it is your choice. I cannot say which is better.
    I put in normal lidded CPUs into my Mac Pro 4,1 without much problem.
    I did not even count how many turns when I detach the heatsinks off.

    For me, I
    - used 5mm thickness thermal pad to ensure contacts remain intact when lidded CPUs are used in place of de-lidded CPUs
    - no washers (use by feel of tightness when tightening - clockwise)
    - no cutting of tabs from the heatsink connector.

    once I feel there is some tightness of the screw, I stop. I did X (cross) fashion as advised by others on the 4 screws. Every round, a quarter turn of the screws to avoid over-tightening.
