Athlon 800 temperature

[Guest]

What temperature range is acceptable for my athlon 800?

Should be about 30's to 40's Celcius.
My A7V w/ TB 700@850 is around 38 to 48C. Another one Abit KT7-Raid w/ TB 700@850 is a little bit lower (28 to 39C).

around 30 C for idle speeds and about 40 C for load, but i know that the amd chips do run alot higher then the intel and i've heard that they can handle alot more heat so you should be fine if you can keep these temps

AMD's absolute temp maximum is 90 C up to 1000 MHz and 95 C over that. Anyone even close to these temps is one step away from a toasted CPU.
AMD's specs contained in "AMD Thermal, Mechanical, and Chassis Cooling Design Guide" (p. 13, Publication # 23794 Rev: B Issue Date: October 2000) gives the following guidelines:
· CPU up to 48 watts: C/W of .55
· CPU up to 55 watts: C/W of .41
· CPU up to 70 watts: C/W of .32
C/W means that for every watt the CPU radiates, the heatsink is supposed to cool the core by C/W x watts plus ambient temp. AMD specs system temp at 45 C, which is on the warm side. What all this means when you run the numbers is the following:
· CPU up to 48 watts: 26.4* + 45 = 71.4 C
· CPU up to 55 watts: 22.6 + 45 = 67.6 C
· CPU up to 70 watts: 22.4 + 45 = 67.4 C
*(48 x .55)
Now that's AMD's Guideline; if you're overclocking, experience has been that temps in the mid 40s and up will start to impact stability. Temps per AMD are OK at normal speeds and voltages, although anyone used to Intel's temps has a hard time when they see numbers like this.
So if you just adhere to AMD's spec, anything over 67 C is not recommended. Hopefully you do better than 45 C case temp, so you should knock at least 10 and better yet 15 C off the 45; this gives you something like 50 C, assuming a 30 C case temp. That's about the upper end of "acceptable".
