Come on baby put out my fire!!!!!

I seem to be having a slight heat issue with my new AMD 850 T-Bird (not overclocked). It's on a Abit KT-7A Motherboard with 256 PC133. I have an Intel Heat sink + fan from my PIII 800 Boxed set on it now with thermal paste. (I'm using this heatsink/fan because the one I ordered didn't fit on this board) The mid tower case has one case fan in the front. The processor from start at room temp takes just over one min to get all the way up to 145 degrees F. Needless to say it then locks up. Anyone have any thoughts as to why it's heating up so darn fast? Thanks for your help.

YEs, the heatsink from the PIII isn't up to the job of cooling the AMD. I wouldn't run it with that HSF anymore or you do run risk of doing serious damage to the chip.

Get yourself an amd approved heatsink. Putting a heatsink from a PIII is not just risking high temps, but you may have crushed the cpu core.

Thanks for the idea. Does anyone have any recommendations as to which fan will fit this the KT7A? The approved fan that I ordered with the processor didn't fit and that is why I was using the one off my PIII. I was unaware that the AMD T-Birds were this fussy about heatsink/fans. (have always built Pentiums) Thanks again for your help.

I like the Thermaltake Volcano II, it's one of the few Thermaltake fans that actually fit easily on the KT7 boards.

Coolermaster also makes a pretty good Athlon fan, but the model number escapes me at the moment.

Any of the approved CoolerMaster or TYaisol range. Both cracking coolers. Personally I don't like any of Thermal Takes fans, but that is personal preference.

Thanks for the help. I have a Coolermaster DP5-6H11 on order it will be here this afternoon. I hope this fixes the problem and there isn't any permanent damage to the processor.

Well the new Heatsink and fan helped quite a bit. It's running at 111 to 113 now. What is the average temp for a T-bird 850? Either way I think it should be fine.

well... my 900 is clocked to 1 gig, and it runs steady at 36oc... dunno what that is in Farenheight.. but that is with a few extra fans thrown in..
It used to run at 45 before.... creeping to 50 under heavy load

I'm still having problems with my CPU getting up to 61 under the heaviest possible load. 40 under nomral load. 45-50 under standard win2000 application load.

But if I do somthing VERY intensive like tribes 2 it will hit 61. With 55 being what I take as the most you want it to run at.


This is an athlon 1333. I have an exsaust fan on order that will hopefully lower it a few degrees, however I just think the Athlon aproved heat sink that I baught packaged with the CPU and moboard has to be improperly attached or thermal compound is not properly spread.

Any opinions?

Thanks!

I wouldn't worry about it unless you are getting lockups, errors etc. Mine has been constantly running at 56C for the last 3 days now with 100% CPU Utilization, with no problems whatsoever. Not even a hint of slowdown. Prior to cleaning the fans out 3 days ago and hoovering the inside of the case, it was constantly running at 61C for about 3 weeks. This is with 8 x 120mm (not 80mm as I thought before) as well & a AMD recommended HSF!!! Little tip that I discovered a few days ago, if you turn the front fans around so that they draw the air out (against AMD's recomendations), the CPU temperature dropped from 61C to 56C under full CPU utilization!!!. Whether or not this is coincidental or not, is another matter, but 'Cobra' mentioned that his also done the same when he reversed the front fans. I know that this is not bad circulation around the case as all cables are tied & pressed flat alongside the side of the drive bays leaving the maximum amount of space for circulation. I may have to try the ThermalEngine coolers next.

Yep, using that PIII cooler wasn't such a good idea. AMD CPU's don't shut themselves down when they overheat, so it's a really good idea to only use AMD-approved coolers.

Perhaps this review'll help: http://www.virtualhideout.net/articl...sf/index.shtml

Okay i'm going to put a new heat sink/fan on this thing.

AN update: NO MATTER how low I get the case temp the CPU is still going nuts on temp every time I play games or other tasks that are hard on the CPU.

I droped the case temp 7 degrees cecleus with a very creative fan setup and better airflow. The CPU still heats up to *67* celc. after an hour of tribes 2. Eventually it will lock up at those temps.

After exiting said games it will plummet to 38.

Some more information about this. After extended testing temps of 71 have been reached. I'm realy confused.

To give you a little history. Maybe somone can help.

My last system: When I first put my gforce2 card in my old pII 450 it started overheating. Put an AMD slot cooler on it and no more problems.

Transfer same gforce2 card to new system it overheats and freezes aswell. Case temperate has been droping below 30 celc. so in no way is it related to venitilation. Is it possible that the chip is simply defective. Or is my "Approved AMD cpu cooler" that came WITH the chip from AMD simply not cutting it?

Again at idle time the temperature is NORMAL for AMD idle temps. Some times durring idle it is actually well below average temp. Its when I put load on it... it goes from normal to *30* degrees celsius warmer, and then shuts down.

I am so lost :(

Thanks for any help again.

Just came across one of these babies the other day. http://www.hardocp.com/reviews/cooli...sonic/v604210/

VERY cool, both literally and figuratively! :)

Ya know, this is a wild shot, but how hot is your chipset getting? Abit is starting to place coolers on their chipsets to combat stability problems. You said you had a GeForce2. Does that have ample cooling? If it overheats your PII and you new Athlon, is it possible that the card is the culprit here? :confused:

I have been wondering the same. The chipset and card both have fans on their heatsinks yes.

Its not the card that causes the hangs, but it may be the card that sends extra heat to the CPU.

However, with the distance between the two. And the fact that I have 2 fans right next to it would lead me to believe that it can't possibly be pumping enough heat to send the cpu up 30 dang degreesc.....

Ok, I didn't read the whole thing, but it doesn't look like enough surface area of the HSF is in contact with the CPU for adequate heat transfers to me.

I've got one of the silver finish ones, and it keeps my 1GHz a LOT cooler than the orbs did. (27 C idle).

This page is there to answer the common question: "My CPU is running at xx degrees, is it too hot?". Here are the maximum temperatures for the most popular CPUs.
Note that these values are for CPUs that are not overclocked. Overclocked CPUs may run unstable even if their temperature is way below the maximal specified temperature.



AMD Athlon and Duron

Socket A CPUs (Athlon, Duron) up to 1GHz 90°C
Socket A CPUs (Athlon) 1.1GHz or more 95°C
All Slot A CPUs (Athlon classic, Athlon Thunderbird) 70°C



AMD K6 series

All K6 CPUs (166-300MHz) and most K6-2/K6-III CPUs 70°C
K6-2/K6-III CPUs, model name ending with X (e.g. K6-2-450AFX) 65°C
K6-2-400AFQ (uncommon) 60°C (!!!)
K6-2+, K6-III+, most mobile K6/K6-2 CPUs 85°C
mobile K6/K6-2 model name ending with K (e.g. mobile K6-2-P-400AFK) 80°C

The temperatures specified for AMD CPUs max case surface temperatures. These CPUs do not have an internal diode to measure CPU temperature. The accuracy of the CPU temperature measurement depends on the motherboard; therefore, it is possible that the CPU overheats even though the CPU temperature reported by the motherboard is below the specified maximal temperature.


Intel Pentium III

Pentium III Socket 370 500-866MHz,
Pentium III Slot 1 (first generation, OLGA) 550-600MHz,
Pentium III Slot 1 ('Coppermine') 500-866MHz 80-85°C depending on model
Pentium III Socket 370 and Slot 1, 933MHz 75°C
Pentium III Slot 1 933MHz 60°C (!!!)
Pentium III Slot 1 1GHz 70°C for newer versions
60°C (!!!) for older version
Pentium III Slot 1 1.13GHz (first version) 62°C (!!!)

Pentium III max temperatures are the maximum temperatures reported by the thermal junction inside the CPU.



Intel Celeron / Celeron

Celeron 266-433MHz 85°C (max. CPU case temperature)
Celeron 466-533MHz (0.25µ) 70°C (max. CPU case temperature)
Celeron 533-600MHz ('Coppermine) 90°C
Celeron 633 and 667MHz 82°C
Celeron 700MHz and more 80°C

Celeron max temperatures are the maximum temperatures reported by the thermal junction inside the CPU, unless otherwise specified.


Intel Pentium II

Pentium II (1st generation, 'Klamath') 72°-75°C depending on MHz
Pentium II (2nd generation, 2.0V core), 266-333MHz 65°C
Pentium II (350-400MHz) 75°C
Pentium II (450MHz) 70°C

Pentium II temperatures are the maximum temperatures of the thermal transfer plate (on which the heatsink is installed).


Intel Pentium 4 (Willamette)

Pentium 4 1.3GHz 69°C
Pentium 4 1.4GHz 70°C
Pentium 4 1.5GHz 72°C




Intel Pentium Pro

Pentium Pro, 256 or 512K L2 cache 85°
Pentium Pro, 1MB L2 cache 80°C

Pentium Pro temperatures are maximum surface temperatures.


Note: For information on the maximum temperature of less common CPUs (mobile CPUs, VIA/Cyrix, older CPU models) and other electrical specifications, please visit Chris Hare's Processor Electrical Specifications page.
The information here is provided WITHOUT WARRANTY of any kind. If you are designing a system and need to have accurate information on the maximum temperature of a specific CPU, please rely on the information provided by the CPU manufacturer, and not the information here.

Last update: January 29, 2001. Future CPU models (even if they are marketed under the same name/with the same MHz) as the CPUs mentioned here may have different thermal specifications

Had a friend with similar problem heat from T-bird and Geforce were to much added larger PWS and 3 additional fans now it runs smooth.
