System temperature question

[gogogo5]

Can someone please tell me what the safe operating temperature range for an Athlon 800 should be? (there has been no overclocking).

Also, what is the safe temp range for a motherboard running this CPU (I have an Asus A7V).

I am trying to see if I need to improve the cooling of my system.

Thanks
-David

Hi David,

There really isn't the perfect temperature at which to operate a system. The best answer is the lowest you can get it at a cost reasonable to you! However, there are some facts you should know. The following list of numbers are the comparative failure rates of an Athlon or Pentium-like microprocessor device, normalized to 25°C. Note that at 41°C, the failure rate doubles, and at 59°C it quadruples. Thses numbers will give you a rough guide of temperature versus failure rate...then you can set your goal and cool accordingly. Also, remember that if a device operates at a higher temperature for a short period of time, the likely effect on failure rate is small. So, those uncooled (un-air-conditioned) days that your system is subject to during the summer months do do any real harm!

Remember, everything that you do is a tradeoff...and perfection in form and performance is dictated by your tastes and wallet!!!

Good luck...

David, I've got an 800 Slot A O/C'd to 950 running stable at 44C 24/7 at 100% usage cracking RC5. It's been running like this for a little over 3 months now. Hope this gives you an idea of a comparison to where you're at.

David --

I'm running an 800 slot A, OC to 867 and average around 40-42 at the CPU and a case temp. around the 35 degree mark. I did read somewhere that you shouldn't let your CPU run above 125F though.

i hope my fop-32 and artic silver get here soon. running around 50c ,and i want to push it faster. duron 600@800 it will run 900 now but it get's to hot ,and i don't want to kill it.

My Slot-A Athlon 900mhz @ 1,000mhz runs in the range of:

Idle: 99-108°F (37-42°C)
Load: 110-118°F (43-47°C)

The range varies so much due to my homes central heating. As long as no one else cranks up the heater, then I stay at the lower end of that range.
