How hot is too hot? AMD 2400?

audimaniac · #1 (**permalink**) 27th October, 2002, 10:35 AM

Gents,
Currently have a SLK-800 and 80mm 40CFM fan in a pretty poorly ventilated area..It is over clocked nearly 300MHz 15x152 at 1.75V but the temps are a bit high from what I can gather from this forum. Idle is around 135&deg and under load will climb up to around 155&deg. Is this getting too hot? I have my warnings in my BIOS set to 70°C and 80°C shutdown.

Advice?

Can you get the temps in celsius? Im totally useless with Farenheit :P

As a general rule 55c overclocked is the cut off point, but if its stable, its fine

Gents,
Currently have a SLK-800 and 80mm 40CFM fan in a pretty poorly ventilated area..It is over clocked nearly 300MHz 15x152 at 1.75V very stable..but the temps are a bit high from what I can gather from this forum. Idle is around 54° and under load will climb up to around 60° and I have seen as high as 65°. Is this getting too hot? I have my warnings in my BIOS set to 70°C and 80°C shutdown.

Advice?

Currently I have two 92mm side panel fans in addition to the 2 integratated case fans...I suspect ventilation is my biggest problem. What about my threasholds? Too high for warning and shutdown?

Welcome to AOA, audimaniac!

135F=57C, 155F=68C. In other words, too hot! I suggest shutting down the machine until better cooling is brought to bear. Then again, losing a CPU is real problem for me. Perhaps you have trays of them?
Many folks say "if it's running, it's not too hot." And the accurate measurement of CPU temp is usually a problem with K7 CPU's. It's your machine!

While the present fan on your Thermalright is nice and quiet, it's inadequate for the present setup. We also don't know how much air is being forced through your case every minute. If temporarily removing your case's left side cover produces a noticeable drop in mainboard and processor temperatures, more case cooling is called for.

Were this my machine, I'd slap a 80mm King Size Delta "Screamer" on top of the HS. 68 cfm will help. 80 cfm will help a little more. Both are loud and annoying. If installing a finger mauling 80mm(with the case buttoned up) doesn't make much difference, the amount of air flowing through the case must be dramatically increased.

While we're at it, could you please let us know how your HSF was installed? Thermal paste and all that?

Changing the 92mm's to more powerful one's will help. But--if the hot air isn't being sucked out of the case, all the intake volume in the world won't help very much.

Thanks for the information..I do have an 80mm Vantec 80cfm 55dB but it is too damn loud. But would be a good test to see how big of difference it makes on this Oc'ed system. The fan currently on the CPU is sort of a junker 80mm ThermalTake. Do you have any suggestions for say a 50cfm fan 80mm that is somewhat quiet?
I did use Artic Silver3 for the thermal paste but do not have any shim of any sort..I do have one it is just on not being used...should I use a shim? Also maybe I should get a larger 60mm fan that can get some hot air out of this case as the ambient temps in the case are 36&degC..is that too hot too?

audimaniac · #6 (**permalink**) 27th October, 2002, 12:07 PM

Just put in my Vantec 80mm 84CFM 55dB fan...temps are now 51-52°C ambient case temps are 36°C

But damn this thing is loud now..sound like one my Sun Netra T1's ;-)

Take the case side panel off, see how much that drops your temps by, if its more than a few degrees you really need more case ventilation

Athlon XP 2200+Thoroughbred, stepping 0 \Max. core temperature 85C

Athlon XP 2600+Thoroughbred, stepping 1 Max. core temperature 85C

X-Bit Labs (a reliable source IMHO)

The truth is, these chips run hotter than previous steppings, which had 70 or 60C limits. So, I think you are OK. I'm running mine at 52C at full load with a similar setup, see sig below.

Weyell, when you're overclocking you have to deal with a lot of extra heat. The only way to beat the noise of air cooling is to go with a refrigerated case, or a water cooled system.

I recently read that all of the fan manufacturer's lie through their teeth in the noise specs that they print. And they don't say that their fans make more noise than they actually do!

The loud 80mm you have seems to be giving you good CPU temps. Screamingly loud boxes are disliked by lots of people. If I had the same temps and couldn't stand the noise, I'd back down on the overclock first. Then I'd try a 50 cfm Sunon 80mm on the HS. They aren't whisper quiet. But they are when compared to ~80 cfm monstro 80mm's!

Some people swear by shims. Their only purpose is to help the ham-handed avoid cracking their fragile AMD slugs. As you know how to be careful, a shim is of no real use.

The CPU is too hot when it becomes unstable, or when it reaches 85C, whichever comes first.

Some AMD chips are rated for 90C, but usually they become unstable way before they reach that temperature. Some linear voltage regulators are design with 130C in mind! ICs can be all over the map as far as acceptable temperatures go.

this new tbreds runs cool

my temps with an xp2400+ and alpha pal 8045 delta cooler @ 7volt(underclocked delta

) are:

2000mhz 1,65 vcore=32 c
2333mhz 1,95 vcore=45c

max temprature i saw @2333mhz was 47 c

My 2400XP is running with an SLK-800 and a 80mm 30cfm fan @ 2.0volts. It's rock solid at 15 x 158 = 2.37ghz.

It idles between 96-102F and under full load it can go up to 108-110F.

Get rid of that monster 80mm...

Use a thin coat of Artic Silver 3 on the CPU, make sure the heatsink is seated properly. Most importantly, make sure you are getting good airflow though your case.

I have 3 80mm 30cfm's for the case. One on the front is blowing in and the 2 right behind where the CPU sits under the powersupply blowing out. My case temp is 73F (23C).

That is pretty darn cool..I am 120°F right now and 93°F in the Case. I have 2 92mm Fans on the side of the case, 1 on the Front, 1 60 mm (weak sauce fan) on the rear, and the Enermax Dual Fan PS...plus a 80mm 36cfm fan on the SLK-800. I just ordered a stronger fan for my CPU variable up to 76cfm at 48dB so we will see how it goes. I think my biggest issue is air flow as currently the PC is in a cubby in the my desk..recently I took the jig saw to the desk to give it some more air flow. In addition I have lowered my OC from 15x152 at 1.75v to 15x145 at 1.65v. In addition the CPU does have a thin layer of artic silver 3 on the die.

I think your problem is mostly your case air flow, like you stated.

Although, what's the temp. in the room? A case with good air flow should only be a few degrees hotter than the room temp.

However, if this is an uncooled room on a warm day 82+F that's the real problem. Otherwise it sounds like your "cubby" is the problem... maybe remove the back wall of it.

Ambient Room Temp 72°F ..just ordered a monster 60mm fan for the case to exhaust more and replace the junker stock 60mm...so we will see

This is for the louder than the Netra T1 effect then huh?

Monster is a bit of an exageration around 30dB 21cfm where the current 60mm case fan is POS. The fan that was extemely loud was my Vantec 80mm at 55dB 82CFM...very loud too loud for my "home" tastes.

I don't know.. I have a slk-800 that has a 32.5cfm 80mm clear LED fan on it and my 1600+ is at 1.80v with the fsb at 180 right now..

temps are 45-47c loaded hard..

If i were you I would take the slk off and make sure it isn't on backwards.

Heat sink on backwards?! How is that possible? Didn't know that the heat sink was directional.

Help
