The 50c temp with 2 cores at 100% isn't bad, but Intel says 72c is the max. To me, 70c is a little too close for comfort. Right now, the bottom third of the cooler gets no airflow at all so hopefully a properly fitted fan will cool it down some. I may have just had one of the voltages too high when I had it at 3.6Ghz. I've got it at 3.0Ghz now, and it stays under 60c at full load, but I'm still getting used to these new overclock settings. I'll probably just read about it until I get my fan sorted, and then try for 4Ghz.

I got a different fan. It's 120 mm vs the original 80mm that didn't clear the ram. At idle, it's down to 22c from 26c. At full load with prime95, it's down to 46-47c from 60c. It's also not as loud. This is with the X3440@3.00 Ghz. I haven't tried to see how high I can go yet. I have 6 temperature readings from the motherboard. One for each core, one that seems to be the average of the cores ( Tcase?), and one somewhere on the board that stays at 26c. My original plan was to overclock until the core temps got to about 65c at full load, and be happy with that. What I've been reading about TjMax hasn't made it clear to me yet. Tjunction, the connection between the cores, is the hottest part of the chip, the likely failure point, and it's temperature can not be directly measured. The TjMax for this chip is 105c, so if I keep Tcase at least 20 degrees less than TjMax, 85c, I won't break anything. I'm not sure if that's the right way to think about it or not.
Quote: So are you saying that you never measured the fps difference between the systems?While my measurement process wasn't the most scientific, it wasn't completely seat of the pants either. I played the same game for every test, Mario Kart Wii. I think the best place to compare speeds would be the cup select screen, but I didn't write them down for the E8400. E8400@3.0 Ghz: Fullspeed when out in front and no other cars are on screen. Drops into the 40's at times. Two player halfspeed. E8400@3.6 Ghz: Almost always fullspeed. Sometimes a steady 60, sometimes alternates between 59 and 61. Two player about 50 fps at fastest. X3440@2.53 Ghz: Gets close to fullspeed, but I never saw over 55 fps. Drops to 30's at times. I didn't try two player. X3440@3.0 Ghz: This is where I am now. It feels just like the E8400@3.0 Ghz. Same speeds I've had for a year. X3440@3.6 Ghz: Almost always fullspeed. hopefully slightly faster than the E8400, but hard to tell. I may set the E8400 up again and compare the speed of the cup select screen. I have never had that at fullspeed. The X3440@3.6 Ghz gets 46 fps. Is there a better way to measure? 12-14-2012, 12:12 AM
You are a little confused on what Tcase is. It is the temp that can be measured by a thermocouple embedded in the heat spreader. So for the 72 degrees or whatever it is Tcase that means if you using that method of temp measurement the cpu should not go higher than that. It is only used in the factory. Your board can not give you the Tcase reading. I have seen some review sites modify their IHS to get these readings but for most consumers Tcase should just be ignored. Go with TJmax and the generally approved temps of the overclocking communities.
