    Hi,

    I have recently noticed a thing called Distance to TJ Max (using RealTemp). However I have no idea what are they for and the safe ranges.

    I am currently @ 3.5GHz and around 41oC (Celcius) idle and around 67 under full P95 stress test.

    My distance to tj max is between 51-55 for all cores.

    Am I in danger of frying my chip? :p

    edit: Ambient room temp is around 27oC(Celcius).

    It's roughly the point where the CPU begins to automatically throttle itself.

    I'm surprised - no jokes about using Google maps to figure it out? :)

    No, you're not. Most people prefer to keep T-junction distance over 30 degrees so 55 is perfectly safe.

    this sounds counter-intuitive, but distance to tjmax is a more-correct temperature measure than "temperature" for core2 based cpus. intel has decided for reasons unknown to NOT give users the true tjmax temps, so makers of temperature monitoring programs are forced to guess. most programs guess that tjmax is 95c for a q6600. When the temperature monitoring programs display a load temp of, say, 65c, they're actually reading a "30c to tjmax" temp from the thermal diode on the cpu. You can set coretemp or realtemp to display distance to tjmax as the primary display.

    I would try, at all costs, to keep the delta to TJmax over 35C, especially if you are putting a lot of volts into it..
    I really wanted mine to be at 40 but I'll have to lap the HS and probably IHS to get it there.. I have Tuniq 120 and @ 1.4volts and 4.1ghz it gets down to 30C to tjmax sometimes 29C which I don't like so It's back at 3.8ghz at 1.31v and around 38-40C to Tjmax, granted that the TJMAX temps I'm giving you are the absolute highest that my cpu hit while running at maximum load under orthos or occt. Normal temps even running 3d games and such are going to be less.

    When I read the threat title, I thought, "what the hell does a discount clothing store have to do with computers?"

    rofl :p From UK too?

    edit : and thanks to the rest for clearing it up. I did use google but I got conflicting answers and no "official" answers so I guess this is a better bet :p

    I would try to keep distance from TJMax at around 15 or more.

    damn! you run em hot! Thats 80C in Realtemp or 90C in Coretemp on an E8400. (I've ran mine this hot before also, but would still recommend ~30C or more)
