Well, I did alot of reading about the Tj-max, and all.

I use CoreTemp, RealTemp, CPU-Z and last but not least important good old Prime95.

This is my first PC to learn to overclock, I think I got it down pat. It's been stable with nothing else touched but the FSB on my P5Q PRO motherboard.



At stock speeds, with stock cooler. with a Thermaltake Armor case, under load with Prime95 it reaches 58c/55c Core temps.

Now with a slight little overclock of 3.221.5 Mhz (3.2mhz) It only reaches 63c/60c.


I searched all over the place and never could find an answer about how high should I let my core temperatures reach with stock cooling.



I Know when I had it clocked to 3.4GHZ and ran Orthos the top temperature was only 62c.
I've run the temperature things when i play games with the slight overclock and it never ever gets even close to the temperatures you reach on Prime95/Or Orthos.



I know there is this chart


Scale 2: Duo
E8x00: Tcase Max 72c, C0 Stepping, Tjunction Max 105c, Vcore Default 1.250, TDP 65w, Delta 15c
E8x90: Tcase Max 72c, C0 Stepping, Tjunction Max 105c, Vcore Default 1.250, TDP 65w, Delta 15c

-Tcase/Tjunction-
--70--/--85--85-- Hot
--65--/--80--80-- Warm
--60--/--75--75-- Safe
--25--/--40--40-- Cool


or should i seriously not worry if it gets close to 75c like this Tjuntion tells me to do? Or should I stay in the ballpark of lets say 65. And be in the middle of cool/safe.

I'm pretty sure anyone who had experience with overclocking will suggest an aftermarket cooler. So, I will. You would really benefit from getting an aftermarket cooler if you want to overclock. That 58/55 will most likely become 48/45. Something like the CM Hyper 212 Plus should do.

I think the Intel tech literature says 71.4 C.

Basically, stock cooler otr not, keep the load temps under 70 C.
