Another delidder here! I have to thank this thread for giving guidance (and confidence) to get this done! Unfortunately I did not overclock before the delid, but I did see a 11C drop in loaded temps at stock speeds under Prime95 load. After looking at everything online I figured I would go ahead and delid before even starting to OC. With my custom cooler, my load temps at stock went from 19C to 8C averages on my hottest core. I used Gelid extreme both on die and replaced IHS.
I'm currently in process of OCing CPU, now at 4.9Ghz. I cannot remember voltage setting for my life right now (at work) but I believe it is around 1.3-1.32, but I'm only at 38C max on load so I think I have some more room to go higher. I can only wonder what the temps would of been without delidding, as I've heard at high voltages the stock space/TIM made great coolers ineffective. Again, thank you guys/girls!
