A friend has the following system:
Asus A7V333 Motherboard
AMD Athlon 1333 (1.4GHz)
GeForce2
256 Meg ram
cd rom + cd burner
modem
1 floppy
1 hard drive.
The mobo temperature is often around 33C
The CPU temperature would often be in high 60's. He even had 84C.
We installed a Volcano 7 which keeps the CPU temperature idling at 55C and will go up into the 60's
The core voltage is showing around 1.77 Volts and I think it should be 1.7 for this CPU. We have the power supply fan and a case fan sucking air out and the volcano 7 on the CPU. The video card also has its own heatsink and fan.
He gets instability as the CPU temp nears 70C.
The volcano 7 fan speed is supposed to be variable. We don't notice much variation and will only run around 4000 rpm when it is capable of up to 5000 rpm. (I think)
Any suggestions?
Overheating Athlon CPU
well the fan on the v7 is stupid...it measures the case temp not the cpu temp...You can remove the fan and push the green thermo probd down into some of the pins...that might help a bit.
I assume you guys are using artic silver or some other quality goob with the combo?

More cooling is necessary....

Two things to consider here - more fans and / or another CPU heatsink / fan assembly. You didn't mention an intake fan, such as mounting one at the front of your case. You need to pull air into the case, not just suck it out. The general idea is to move air across the CPU area of the mainboard. The configuration of your case helps determine what is possible. If you don't want to address replacing your Volcano 7 heatsink / fan assembly, then at least look into an intake fan up front, and even cutting a "blowhole" in the side where you install another intake fan, this time blowing down on the CPU / Videocard area. Again, your case design helps determine what is possible.
Your goal should be to have that CPU idle temperature below 50 C, and under load it should be no higher than 55 C. It's no wonder your friend is having stability issues if the temperature is getting up into the high 60's.
Regarding the Volcano 7 fan, you probably want that one running at high speed, since this is not the best heatsink to be using. You might consider just installing a fan that runs at 5000 RPM, or if money can be spent, replacing your current CPU heatsink / fan assembly with a more efficient copper-based unit. You are probably looking at $40 to $50 for that upgrade. The other fans / blowhole mod can be done for $20, if you have the tools (metal shears or hole cutter for a drill) to do it yourself.

well, to be fair, the generic brand i had coulda been bad. the system would freeze up after some stress. i would turn it off for a while, then back on and it was all good for a while longer. having replaced the ram with some name brand, the problems stopped. and the cpu temps were never as high as they were before.

I have same mobo, the Asus reads the actual core temp, and it's usually 10 to 15 degrees higher than mobos that have the in socket thermistor. Do your homework on it, check out the stuff on this mobo on amdmb.com in Asus mobos. You'll find average temps in the 50's. Using an AX-7 on my 1700, with a system temp of 32, my idle is 51C right now, goes up to around 56 at full load. And has been this way for several months, rock solid. NO crashes. It's mildly overclocked too, at stock voltage. This same cpu on an older Epox, with a good heatsink was 10C cooler. Same case , components.

"my overclocked brain runs much faster with the thought processor disabled"
athlon cooling
Here's soem facts i know.
1.) The Athlon 1.4 GHz cpu is the hottest running cpu Athlon makes, possibly the hottest running cpu on the market. The reason it is this hot is because the processor die is much larger than the current XP processors.
2.) My brother has that processor, and he has to use a 7200rpm cpu fan with some thermal paste to keep the temperature down.
3.) The cpu never went above 85C, because when an AMD cpu reaches 70C, it starts to melt and running the cpu at that temperature for too long will eventually kill the processor, (about 30 seconds would leave you with a fried cpu). This would leave me to believe your getting false readings.
4.) I highly doubt your motherboard could support PC2700 with a cpu that old, and i have never heard of ram effecting a cpu temperature.
What I would do...
1.) I run my Athlon XP 1900+ with a 7,600rpm Dyatron fan and thermal paste. It runs at about 40-50C.
2.) The room temperature will effect your cpu tempurature greatly, so try to get a fan on the computer if you live in a hot area.
3.) Get a nice big ass fan that runs at atleast 6800rpm and some non generic thermal paste. I recommend Dyatron fans for Athlons, but go to http://www.amd.com and look at approved fans.
I hope this helps you, if your cpu is still overheating, you should really figure out why.

One of my past jobs as an Electrical Engineer was writing specifications for Space Qualified active components as a Component Engineer. I just couldn't ignore your statement about why the 1.4 GHz T-bird is the hottest CPU made ("The reason it is this hot is because the processor die is much larger than the current XP processors."). This is not the reason that particular CPU runs warm; here's why:
(1) Heat is generated due to the resistance to current flow. The number of transistors switching, the voltages applied across the source, gate, and drain of the transistors, and several other factors play into the power consumed (and heat generated) by the CPU. Everything else being equal, having a larger die (which gives you more exposure to the heatsink for thermal transfer) would give you a lower CPU temperature, not a higher one.
(2) The ability to lower the CPU voltage, which can be done by decreasing the process size (going from 1.8 micron to 1.3 micron trace size) because less voltage is required to achieve "saturation" in the switching transistor, will decrease the CPU temperature. However, the new Athlon XP Thoroughbreds did this and also had a decreased die size, which meant less surface area to dissipate the heat to the heatsink. Hence we don't see a significant decrease in CPU temperature with the decreased CPU voltage of these CPU's.
(3) The Athlon XP has several architecture changes, when compared to the Athlon T-bird, that accounted for the decrease in thermal dissipation. I don't remember where I read the particular changes, but I believe the idea was to perform the functions more efficiently (maybe operate fewer transistors).
I hope that makes sense to you. Additionally, I hope AMD continues to evolve the Athlon series, as I think they are far more advanced than those Intel Pentium IV chips. I simply refuse to buy an Intel CPU until they change their design and their marketing ploys to run out the smaller manufacturers.:jedi

Yeah, I guess that was your point. I prefer a slower (and larger - say 80mm) fan and a better heatsink combination, as I can't stand to hear any fan running above 4000 RPM. It's really not necessary either, if you can modify your case to support good air flow across the CPU. You might end up with three or four 80mm 2500 - 3000 RPM fans to get the same CPU temps that your 7000 RPM screamer is producing, but the added cost will keep you in there gaming much longer!
Let's just say that cooling the CPU should be our number one priority, and getting that accomplished is up to the individual and the amount of cash on hand.

something good
