When I noticed the PWM temps rise & the board started rebooting with the TRUE I had just put it in the case after running Orthos overnight @ 475 x 8 on my Tek station. I then took the board back out & looked all over it & found the TRUE was buckling the board. I guess when the TRUE was pushing down on the board it was fine but once I fitted it in the case & the weight of the true levered down on the board the warping must have been too much for the PWM to handle hence the temp & reboot problem.

I messed about for hours re-mounting the TRUE in the case but I could not get a decent mount where all my cores were running even so I switched over to water.

Initially I tightened the D-Tek block up to the stops & it too warped the board so I added a backplate from my old Tunic tower 120 & screwed the D-Tek screws into it, I measures & marked the screws 8mm from the end in an attempt to get all 4 screw at the same pressure. Basically now I only have the 4 D-Tek mounting nipped up literally just taking up the slack on the springs + 2 turns & all my cores run within 2oC of each other under load.

Thanks nzbleach but it was just what I found maybe it can help others maybe not.

IMO we have all probably had many boards warp around the CPU area & it hasn't mattered with 4,5 maybe even 6 Phase PWM's because they were short enough to not be affected by board warp, but these new 8 phase really long PWM's cant take the warping.
