My chip sucks... it has always taken a ton of voltage to get a good OC.....
System Specs
3570k
gigabyte z77x-ud3h
gigabyte gtx770 oc'd
8gb trident x 2400mhz 9 11 11 31 1t 1.68v
2 128gb samsung 840 pros
corsair vengeance case
corsair hx750 psu
etc. etc.
Previously I had a double fan h60 running on my cpu delided w GC extreme TIM. Think I over did it on TIM, but either way it was pretty hot. Settled on 4.6ghz at 1.39v
and temps would get up around 80c on prime95 after a long run, and around 90c on burn test after some time. But it was stable there... at 4.7, even with more voltage it might pass prime and burn test (until I would shut them down due to heat) but ever once and a while I would get an error in WoW or something other kind of instability issue.
I decided to go bare die and see what would happen. I bought an h100, it's running in push pull, my case has 12 120mm fans and inside temps are about 68F right now. I have access to a machine shop, so I put the pegs in a lathe and took off approx (got it within about 3 thousandths) of what the IHS is (mine measured out to 2.58mm). Put everything together (just left the stock TIM on the h100i) and I am pretty impressed with the results.
For comparison sake
Intel burn test before at 1.42v would peak 91c at about test 8 or 9 and I would shut it down.
Now I ran burn test at 1.45v and it peaked at 88c on the hottest core after 15 tests run.
Both these at 4.7ghz.. I am of course going to run it longer, but I am easing into things....
Prime (max heat) before at 1.42v after 30min of running would peak at 80-81c.
I just ran Prime at 1.452v for 30+ min and saw a max of 74c and it has been holding under that without moving for the last 20 min. Of course I will run it for hours after I feel comfortable walking away from it and see what happens.
These are just prelim numbers.. but it's obvious there is a large drop in temps (seeing a larger variance across cores now which is odd, didn't expect that.. maybe 12-14c).... maybe I can sneak up to 1.46 or 1.47 and 4.8ghz before it's over, but I don't know this chip hasn't been very OC friendly.
Attaching a couple pictures of the process.... this was a fun project!
