Thanks for the suggestions. I didn't heed the advice of changing one variable at a time, but through a combination of lowering the multiplier to 40, rebooting, nudging one of the two pipes on the cooler that didn't feel warm in comparison to the other which was warm, and then changing the multiplier back to 45 I have been able to resinstate the performance I had seen temporarily. I am growing increasingly suspicious of the coolant flow but haven't ruled out reinstalling the cooler or replacing the paste being necessary. I am unsure how to determine if the CPU has been degraded, it is quite possible with all the problems I have had, although with adaptive/balanced power saving it wouldn't have been getting 1.35 24x7 which hopefully helps my cause. My research suggested that keeping below 1.4v was the main priority the 6700k. XMP seems to be very problematic with the RAM I have and after the impact of the last time I enabled it I plan to leave this off. I am now set at 1.275v and under a brief test reached 66c under load and around 20 when idle which if it continues would be a great improvement.

After many years of dissatisfaction with my temperatures and overclocking performance I recently decided to re-position my Corsair H100i v2 AIO radiator/fans as front intake, moving the existing intake fan to a top exhaust. This act alone, although I suppose moving the pipes about a bit could have helped, had a dramatic impact giving me temps of low 20s idle and 60s under full load. I had been using adaptive voltage of 1.296 +, LLC level 5, everything else auto or unchanged. I have followed many guides previously and was using 1.35 for 4.5ghz for a long time although the temps were not brilliant, spiking from 30 to 60 under slight load and going above 90 under load. I have tried lowering clock speeds to 40 now and in the past but the difference in temperatures have still been excessive based on what I have seen is typical for such a configuration. I then, regrettably decided to give XMP one last shot, enabling in the bios. As per many times previously since I upgraded from 8gb to 16gb of the same Corsair 3000 LPX memory, this resulted in an immediate temperature increase and after restart/resume from sleep I get code 00 on the mobo and need to press the CMOS reset button to get it to POST at all. I also tried the motherbaords MemOK button at this point which is supposed to tune the timings I believe, but this had no noticeable affect. Now, after loading my saved BIOS profile I am back to terrible temperatures, going over 100 under load and clock watchdog timeout BSODs during realbench which I have had before when I suspect the voltage was insufficient, although now that I have seen it running with only 1.296 as the turbo voltage I am dubious. I do not understand why with the same of profile, going back to the stock RAM speed and applying settings that were working so well, albeit briefly, is giving such vastly worse performance. I would really appreciate any advise as I have tried so many things to try get my machine running at a level I have now seen it is capable of.
