XP 2200+, 8k3a+ getting a cpu temp of 61C!!!!!

[CPUfrier]

I just put together my system: 8k3a+, athlon xp2200+, thermalright ax-7 with arctic silver3, ocz pc3000 256mb ddr...Even in the post it says this ridiculious temps raging from like 50-60C! In sandra it says the same temp...i followed the instructions for applying the as3 twice and i still get the same readings...my system is running just fine and stable..it is not oc'ed, are these temps incorrect somehow? I am very worried...i have also flashed my bios to the newest ones and still same thing

Are you using SANDRA to monitor your temps? She's been known to be wrong sometimes.

Reboot your machine, get into the bios & check the pc health section for the correct temp. If SANDRA is wrong, try Motherboard Monitor 5 to monitor temps.

Nothing to worry about, 60C are normal for the T-bred.

Remember, even though the T-bred actually produces less heat than the Palomino, because it has a much smaller die, you run into the same or higher temperatures at the heatsink. Those numbers sound pretty normal.

I don't get it... If it produces LESS heat, and is smaller... Why would it run into higher temps at the heatsink???

Basically, the problem with the T-bred, is that even though it produces less heat, it is so much smaller than the Palomino that it actually produces as much or more heat per square millimeter of die area than the Palomino. Remember, temperature is not the same as heat. Less heat in a smaller area will often give higher temperatures.

I have been told that the epox 8k3a+ gives the on-die temp reading unlike other mobo's that measure the temp of the air underneath the cpu....so it should be normal :)

Thats interesting, yet a little confusing at the same time... I think i'm gonna register for a physics class this semester :confused:

It's fairly simple once you know how to look at it: Heat is motion, temperature is pressure.

Heat measures how much total molecular motion their is in a substance. So one molecule moving at 1000 and 1000 molecules moving at one both contain the same amount of heat. They both have 1000 units of heat. Temperature is what you get when those molecules encounter something else, and attempt to transfer their heat. The one at 1000 is going to hit something much harder than any of the 1000 that are only moving at one. It hits harder, transfers more energy, and so has a higher temperature. But both systems started with the same amount of heat despite the different temperatures.

Clear as mud, right :)

Heat is what you get when you add up the speeds of all the molecules in the system.

Temperature is how fast the one that hit you was going.

So if you have a smaller die, each molecule must move faster to hold the same amount of total heat. In T-bred's case the difference in molecules to hold the heat is close to the difference in heat, so each one has to hold as much as the Palomino's did.

What is the difference in temps you see between mobo and cpu? I have an XP2100+ OC'ed to slightly above XP2200+ speed (142fsb X 13.0 = 1846gHz), and at 100% cpu output, I see anywhere from 17 to 19°C difference between mobo and cpu (as I type my mobo is at 29°C and my cpu is at 46°C... been running Seti since 7am this morning.

The AX7 is a great cooler. I'm using an 80mm Sunon at 3900rpm, putting out 50cfm. How much airflow does your cpu fan put out? Are you blowing DOWN onto the cpu heatsink?

Is your HS surface seated in good contact with the cpu? Did you perhaps use too much thermal compound? Could there be a strand of hair or fur, or some other foreign particle, stuck in the thermal compound, keeping the cpu from making good contact?

I also lapped my AX7 surface until smooth and flat, before installing it (600 grit emery paper).

Although 60°C is not horrendous, the AX7 should be keeping your cpu much cooler.

I have the same sunon 50cfm fan and it is blowing down(guessing u also got it from 2cooltek.com) there is no furs or anything and i tried twice alreadt with same results.. i put a very thin layer....maybe the new thoroughbred makes that much of a difference as Rugor explained how the die is smaller and stuff

Your problem may stem from case ventilation issues. I use a 120mm fan front/bottom blowing in... a 120mm fan top/rear blowing out, plus the PS fan (actually a dual fan PS) blowing out top/rear, and a slot fan/blower adjacent to my graphics card.

If you have a poorly ventilated case and high ambient temps, even the best heat sink cannot keep your cpu cool.

PS: got my HS/F from 1CoolPC

My system and cpu temps right now is 36c and 57c, so it is a 21c difference.. i have a 80mm fan in the front blowing in and a 80mm in the rear blowing out and just the regualar fan in the psu blowing out the rear

Seriously, you may need to cool your room temp. Twenty-one degrees seems a bit high (like I said, I get between 16-19°C degrees difference, so something else may be going on).

Is your power supply "dual fan"? Does it draw hot air out the upper portion of the computer case (dual fan) and exhaust it out the rear?

Is it hot were you live?

[Grentarc]

Do you have 3 temps that can be monitored.. coz the 36 could be your Southbridge chip.. as the ones with the KT133A chipset have an internal temp sensor..... So the ambient temps you are getting are more likely a Southbridge chip temp
