my Athlon xp 1900 unclocked, works at 1610mhz at 67 Degrees Celcius, is it ok ??
i don't know how to increase the speed of my fan, it only goes 1900rpm, when max speed is 5400rpm

Lao Tze · Wed Jan 09, 2002 11:37 pm

It is a bit on the high side, I would get a better fan. How is your sys temp???

fink · Thu Jan 10, 2002 3:36 pm

That is WAY on the high side. I am amazed that your system is stable at all.

Pull the sidecover off and see if the temps drop. Sounds like you need to be getting a new HSF unit!

67 C is starting to border on dangerous to your CPU. Immediate remedy is neccessary.
As to what's happening to your fan, it sounds to me like either:
1)The fan is on its last legs. Some fans, especially non-ball bearing types spin slower as the age. Frequently its dust clogging the fan motor. Given the fact that heatsink fans aren't designed to be field serviced, replacement of the unit would be your only option. Sorry.
2) I presume your fan is hooked up to the 3-pin fan header on the motherboard. Therefore, it could be that the MoBo is incapable of supplying sufficient voltage to the fan. If you plug the fan into a 3-pin to 4-pin molex adapter, then connect it to a hard drive power lead from your power supply, this would recify the low voltage problem.

ok you have me kind of worried i have a xp1900 not over clocked and under 100% load the temp peaks at 64C. i have some artic silver on it and also a 7000rpm fan. should i worry now?

What type of heat sink do you have that screaming 7K-RPM Delta fan strapped onto? A powerful fan can not always compensate for a poor heatsink design.

<a href="http://www.thermaltake.com/v6.htm" target="_blank">thermaltake volcano6Cu</a> but i have a 7k rpm fan on it.

Jumper42:
The Volcano series should be adequate for the task, since you are not overclocking. They're good, not great, but they should be able to get the job done. You said that you are at 64C under 100% load. How common is 100% load? I can give you instructions on logging this data if you need it.

J5 · Sat Jan 19, 2002 11:24 am

Holy ****. I'm suprised the damn thing hadn't ignited. The volcano series is just fine imo.

Forge · Sat Jan 19, 2002 12:14 pm

Jebus Rice.

Here I have an XP 1466MHz/1700+ unlocked and running 1600MHz/1900+. It is running 1.85V, and I am using a Thermalright SK-6 with a *27CFM* fan. I'm at 111F/40C after ~12 hours at 100% load.

At ~60C, you are running around 150-160F. Get much hotter and you'll be able to boil water on your HSF.

Immediately check the attachment between the CPU and the HSF. Use only a *small* amount of compound. Make sure both the CPU top and the HSF bottom are clean and perfectly flat.

I personaly took a Duron 750 up to 120 (C) for about 5 minutes and then 95 (C) for another 5 or so with out any damage being done to the processor, although the fan started to melt. The fan on a 1U heatsink failed, so I had a Duron750 in a tiny case with a tiny heatsink cooking away. Luckally the duron is still going strong and working as stabily as ever.

Peace, Will

Jumper_42, to add to what Forge said:
Clean the surface of the CPU die & the HSF with rubbing alcohol & a lint-free cloth.
Next, you could "lap" the HSF to ensure a smoother contact surface, therefore better overall contact & better heat transfer. This involves:
1) got to local harware store, buy a couple sheets each of 200grit, 400grit, and 800grit sandpaper.
2) tape the the 200 grit to a FLAT surface, such as sheet of glass (wood desks DO NOT qualify as "flat").
3) set HSF on sandpaper, grasp from top in the palm of your had, begin making slow, even clockwise circles, 50 or untill the paint comes off, whichever takes more.
4) wipe the dust off the bottom of the HSF with the same cloth & rubbing alcohol you uhsed previosly, wait for alcohol to evaporate before moving to:
5) repeat steps 2, 3, & 4 with the 400 grit, only do a minimum of 75 circles this time
6) repeat steps 2, 3, & 4 with the 800 grit, only do a minimum of 100 circles this time
7) DO NOT ATTEMPT the same procedure on the CPU, you will destroy it.
You HSF should now be gleaming on the CPU-contact surface. Apply a THIN layer of thermal paste/grease of your choice, and you should be good to go.

Prelude I would consider yourself lucky. You could have boiled water with that temp so I think it is amazing it even considered working.

Forge · Sat Jan 19, 2002 6:23 pm

Prelude - Yes, it is possible to run those temps for a very short period of time, but I do not think anyone anywhere would claim it is a good idea, nor is it anything one should do willingly.

Prelude · Sat Jan 19, 2002 7:20 pm

Hi. Yes, a note. I do consider myself lucky (although I burned myself pretty well on it) and I was NOT condoning that behaviour. I just wanted to point out that, in my experiance, processers are fairly resistant to temperature. This same duron (before its move to the mATX case) spent most of its life running between 50-60 degrees C with no stability problems. Maybe I just got an expecially die hard chip.
Peace, Will

jumper42 · Sun Jan 20, 2002 6:35 am

thanks for the ideas and help, i am off to the hardware store for some sand paper, well when it opens. thanks again.

oh and for my "full load" i had setti, winamp, and return to castle wolfentein running for about 7 hours and was right around 64-67. idle for me is 58 or so.

any good ideas on a different hsf besides a water based one, i am not 1337 enough to deal with water.

ExcessOrder · Sun Jan 20, 2002 10:49 am

God, how are you people putting out so much heat? I've got a Athlon XP running at 1.45 ghz, and the highest I've seen the temp go is the upper 40s. I use a zalman heatsink, with only 4000 or so rpms of fan on it. Some of you guys must have the heat sinks attached wrong.

Personally, I don't think I would run a cpu if the average temp was above 50c.

ExcessOrder · Sun Jan 20, 2002 10:51 am

I just remembered, the fact that the average temp in my house is 64 (f) probably helps things. I guess that when summer comes along, I'll have to stop overclocking!

J5 · Sun Jan 20, 2002 4:02 pm

Speaking of temps...summer I keep my AC cranked. Nice and cold!

champs · Tue Jan 22, 2002 6:30 pm

I don't trust Tbird CPU temps to within a range of anything less than 10C, unless it's done under some very controlled conditions with almost every variable eliminated. 67C is pretty outrageous, though.

Your temps are almost in the neighborhood of "are you sure the fan is on?". You'd probably know if your 7K fan was running or not, but I had a Tbird with a quieter fan that died -- I didn't have MBM running, and it took a long time for me to notice that it was running temps in the neighborhood of 70C. Aside from that, a big "what he said" WRT to lapping the heatsink, making sure it's seated well, and applying the right amount of thermal compound.

jsbach11 · Fri Jan 25, 2002 4:04 pm

Chickala and Prelude, I don't know what to say. I have an non-overclocked Athlon XP 1900+ and it never gets above 50 C, not even after 24 hours of running the Anthrax screensaver (100% CPU load) from United Devices. I'm only using aircooling from a front and rear fan and a Coolermaster HSF, the EP5-6i11, which was $7 from http://www.newegg.com. I've heard the Tt Volcano 6 is pretty good-it has a cylindrical copper core that connects to the processor die and is surrounded by the aluminum HS fins. That one runs about $13.

Sometimes, adding too much Artic Silver paste will cause the CPU to run hotter than it would without it. That might be a problem, too.

Normally, I would be itching to overclock this XP 1900+, but I'm looking to just get another one to match it in an SMP system in a few months and don't want to take years off it's lifetime expectancy for no really good reason.

If your CPUs are running that hot without overclocking, something is wrong. The XP's, as they get higher in rated clockspeed from the factory are supposed to be running gradually cooler than the Thunderbirds, especially the 1.4 GHz, which is the hottest one.

I wouldn't even be attempting what some of you guys are managing to pull off without water cooling or even liquid N2.

True! I have seen pics where it is gobbed everywhere. You need a paper thin layer fools!!!

is it ok ?
