Is this too hot?

These temps are at 100% usage for 5 hours running SETI, but it still seems hot.
Processor is a 1800+ with Thermaltake Volcano 5, no overclocking

CPU temp 65 C
Hard Drive temp 47 C

I can't seem to find a case temp reading anywhere.

65 on the cpu seems quite hot to me. Anyone think this is too hot? I don't have any stability issues though...

Tell me what you think!

Thanks

MOtherboard is very necessary is not all manufacturers or chipsets read from the same spot....So comparison o ftemps and credibility of temps can be called into question...


I run a shuttle nforce2 mobo and with stock fan I have a 2100+(1.73ghz) oc'd to 2600+(2.08ghz) with 1.57v and I only see max of 55c...

No, it's not too hot. It's hotter than I would expect from an 1800, but 65 should be fine for an AthlonXP.

Not too hot? No wonder some people have their CPUs dying.

Hes running well within his limits.

The Volcano5 is a crappy heatsink anyway.

You're fine.

Just so ya know, AMD says as long as it's below 85C it's fine.

Asus boards automatically are about 5-10C higher than other boards. They do this for a "more accurate representation of the CPU temperature."

The temps are fine in my opinion. As said before, if it's a Palamino, it's normal.

lol yea, from oc boards etc i think some people have the misconception that if their cpu passes 60c it will explode;)

Jeff7181,

Thats very interresting, I dont fully understand the "Thermal Power" notes (5) section. I think I will do more research on this issue.


0roo0roo speaking for myself I would never think a CPU would explode at 60C but maybe at 85C I would! :D

Thanks guys!

Allow stability to continue to be your guide is my advice. Temp readingscan be all over the place so who know's what the actual core temp of your CPU is. As Jeff mentioned they are spec'd for 85c max operating temp and if it's very near that I suspect you would experience instability under extended loads at the very least.

BTW, as to the "no wonder some people have their CPU's dying" they are killing them with voltage ;) With my Soltek nF2 boards clock throttling and emergency shutdown are present and the on-die thermal sensor is read so even leaving the cooler off will not result in a dead CPU :beer: Finally giving AMD parity in that area with Intel where they were sorely lacking for so long. Oh, and yes it works, I experimented with a 1700+ t-bred A in my 75FN :evil: I turned it on with the cooler off,but plugged in to the CPU fan header! and no sooner did it get power than shutdown, the NB fan barely moved. I tried to power on again and nothing. I reapplied Ceramique', reattached the cooler, and viola' just as if nothing ever happened :sun: That board and CPU are still running like champs@2ghz for 1 of my nephews.

I'm not sure exactly what you don't understand... but, what I think you mean is you're not sure what they mean by Typical and Maximum. They're not very clear on it either... but I would assume Maximum would be when the CPU is working at 100%... it creates more heat when it's doing work, which is why everyone "load tests" their CPU after overclocking... cause while it may sit there idle just fine, when you give it a bunch of crap to process, it creates more heat, and also uses more electricity, as you can see from the Processor Current section. So when people overclock, they try to put it under extreme loads that it normally wouldn't see. That's what Prime95 is supposed to do. Typical I'm assuming would be when it's sitting there idle, doing nothing... maybe with web browser or something like that running.
If you look more closely and do some figuring, you can estimate what my processor would be doing at 2300 Mhz on 1.725 volts.

If you look at the amps, for every 100 Mhz increase, the amperage increases by about 12.5% So... you can figure what the amperage would be at 2300 Mhz by adding 12.5% to 46.5, which gives you 52.3 amps. And my voltage is at 1.725, and if you use the basic electrical formula, watts = volts x amps, you'll see that my processor is creating about 90 watts, which is only 4 more watts than if I kept the voltage at 1.650.

So... one could say that this proves all my previous statements that it's not HEAT that kills a processor, it's voltage. Voltage is electrical pressure, if you increase it too much, you increase the stress on other componants... take car tires for example... put too much air in them and they could explode. The question is how much more can you safely ad? And for AMD CPU's the general consensus is 1.850 volts. I prefer to keep mine under 1.750 though.

For poops and giggles, lets see what an AMD processor at 2400 Mhz on 1.850 volts would produce in terms of wattage...

46.5 amps + 25% = 58.1 amps
58.1 amps x 1.85 volts = 107.5 watts

Gettin pretty far away from AMD's spec of 76.8 watts on their fastest processor.

Ok... I'm done rambling =)

Another thing to consider is that a faster FSB, but the same clock speed, will slightly increase the amount of work done... but I don't think it's significant enough in terms of CPU wattage and temps... that will effect the northbridge more than anything else.

this guy takes in leakage into account, which apparently gets much worse after a certain point of overclocking/temperature. http://forum.oc-forums.com/vb/showthread.php?s=a79d202ba70170a82dc5666db6b38d77&threadid=187887&perpage=30&pagenumber=1
