Tech: Processor Temperature?

MattH · July 8, 2003, 13:15

I'm hoping some of the cool tech gurus can help, my knowledge has run out...

I have an A7N8X deluxe mobo (ASUS) with an athlon 2700+. It's underclocked (

) because the computer becomes horribly unstable when I set the Outside Frequency in the BIOS to the correct value.

I'm working on that problem right now (suggestions would be great...). What really scares me is that the processor is running at about 100-114 degrees F. Is this normal? The AMD has some undecipherable tables, and a google search turned up nothing.

Pekka · July 8, 2003, 13:16

To me that doesn't sound horribly high. Don't take my word as an advice though, someone should back me up with this. But that sounds almost normal?

Neutrino · July 8, 2003, 13:25

I'm also on an Asus mobo and my CPU runs at 60-69 Celsius (~150 F). I think the thermal compound between the CPU core and the heat sink was incorrectly applied, or maybe it just sucks

You may have the same problem. Try re-applying some new thermal compound - you can probably get some from a local store for less than $5.

MattH · July 8, 2003, 13:25

I was just reading along somwhere, people were mentioning 70-80 degree temps, probably just some damn supercoolers

General Ludd · July 8, 2003, 13:26

If it was celsius, you should start to worry... Can't say I know what the threshold is for your proccesor, but my old P3 500 got to ~90 celsius and survived.

MattH · July 8, 2003, 13:28

Crosspost with Neutrino-
It's probably cause I don't got no thermal compound

Now where's that #$^& PCB revision #?

Tell me if you find it... I have a A7N8X and have not been able to find it, either.

I'm told that it is beside the printed ASUS logo on the motherboard, but I did not see it anywhere.

Garth Vader · July 8, 2003, 13:45

Isn't that only around 46C? If so, that's cool. Mine runs around 53-56 and I'd like to lower that a bit more. With the OEM stuff it ran around 65 which I thought was way too hot!

So I'm not the only one? I read the same thing, near the ASUS logo it said, nothing there! Well, at least I know I'm not going blind

.

Is it just me or is ASUS support crappy? Their help forum has said "Closed" for months, "PBC Revision" is not found in the KB, e-mail support hidden, etc...

Garth: Right now it's at 52 degrees celcius (processor, according to ASUS Probe), but that's probably because it's been running NWN for 5 hours and I don't have air conditioning. Normal temp is around 47/48 degrees C.

if the computer is actually on fire the return type of the function Is_Computer_On_Fire is undefined......

Zopperoni · July 8, 2003, 14:33

My P4 has never exceeded 40-45ºC.

MRT144 · July 8, 2003, 15:56

when i first applied thermal compound i applied way too much and was around 55C. i scraped some off and left a thin layer. now i run around 45C.

Thanks, Neutrino, helps a lot.

Anybody have a map to the PCB revision?

The board revision is on the board itself. If I remember correctly it is on the left edge by PCI socket 4, down near the mounting screw hole. It's not in very large type, so look carefully.

Mine had trouble seeing the DIMM in slot 2 when I had slots 2 & 3 filled, but slots 1 & 3 worked fine.

The only time I see BSODs is when I am overclocking and I've got the FSB set too high, but not so high that the PC refuses to try and boot into Windows.

Yes, the board revision is on the PCB, in small letters right underneath the
big ASUS logo if I remember correctly..

Something I found on another boards, hope this helps.

MattH · July 8, 2003, 18:58

PCB REVISION FOUND!
Thanks a lot!

Case closed

46°C? That's probably nothing, unless the ambient temperature is something like 10°C.

I read that exact same post while I was doing my own search, but still could not find it.... maybe I need to get my flash light out. Was it really hard to see, MattH?

Unspeakable Horror · July 8, 2003, 23:07

My P750 runs at 33°C, 38°C with SETI

Urban Ranger · July 8, 2003, 23:10

It doesn't mean anything without knowing the ambient temperature and your cooling system.

Unspeakable Horror · July 8, 2003, 23:16

It´s winter around 13°C

. I´m just using the same thing it came with, no upgrades or anything

.
In summer goes up to 50°C sometimes and becomes unstable

As I thought

Skanky Burns · July 9, 2003, 00:13

Mine hovers around 45°C. Its winter here too, but I have a big heater right next to me.

Urban Ranger · July 9, 2003, 00:24

You mean your computer isn't big enough?

It's about here on the Mobo:
A7N8X
________REV 1.04

SpencerH · July 9, 2003, 09:50

I went through this a few years ago with a chip that was becoming unstable in the daytime and was running about 75C. Is that too hot I wondered? The best advice I could find was, "if you touch it and you burn yourself it's too hot". I did, and it was. Optimum temps are as low as you can get em. Get a better fan and cool that sucker down so it runs at 50C at full throttle.

MattH · July 9, 2003, 09:58

By the time I had all the parts, I just wanted to put the thing together. I just used the OEM fan that was in the case. I'm looking for a good QUIET fan, but I'll probably need a new power supply first (current one might have problems, only 300w).

Any suggestions for fan and PS?

Ah, I found it! It was above the logo on mine. Text is small as hell, too.

General Ludd · July 9, 2003, 10:22

Now I just need to know if the BIOS updates are cumulative or if I have to download and apply them all.

SpencerH · July 9, 2003, 11:10

I think the standard answer is that 300W should be OK as long as you're not running too many devices. How many devices is that ? On one machine, I run two HD, two CD-R drives (one SCSI) and a USB smart card reader on 250W.

As for the fan, you may not have too much choice about quiet, the biggest question is how well they cool and whether they will fit on the MB (not just the CPU) heres a site that'll give you some ideas about the possible choices.
