That sounds a bit hot to me, I don't like to let mine get past 50degC. Most semiconductors are (or used to be) rated to 70degC operating environment but the guts of the CPU will be hotter than the surface. I've had processors fail to operate beyond 52degC before and if it should lock up during a write to your disk then you will be in a pickle potentially. It'll depend on the CPU as to the heat tolerance but try and get it cooler than 56C! Get a fan rated for the next faster model of CPU or something. £7 for a fan vs rebuilding an HD is a bargain in my books :o) G Chris Green wrote:

Replying to your own post is probably listed in some psychology book somewhere as a loony archetype but I forgot to mention you might want to service your CPU fan... suck all the dust n fluff out with a hoover or something if it's a bit clogged up. May get you another 2-3 degC reduction! G Guy Eastwood wrote:

A clean out of the heatsink has taken the temperature down to 50 degrees, I think thats about what it was when originally installed. -- Chris Green (chris@areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."
That's not bad >10% improvement in thermal efficiency! G Chris Green wrote:

Thank you to whoever started the CPU temperature thread, it jogged my memory into getting lm-sensors working on my AMD 64 machine Once working I discovered this- temp1: +41°C (high = +104°C, hyst = -26°C) sensor = thermistor temp2: +61.5°C (high = +80°C, hyst = +75°C) sensor = diode The AMD64 is rated for a body temp not exceeding 70C so it looks like I need to take a look at the cooling on my own machine. I am suspicious of the 41C case temp, the air coming out of the exhaust fan just doesn't feel that hot so I will have to look and see where the board thermistor is located and see if there is a hot spot.

It's all in the BIOS and there's a little Windows program that allows me to monitor it while the system is running as well. -- Chris Green (chris@areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

lm_sensors, http://secure.netroedge.com/~lm78/ Doesn't support all motherboards unfortunately (and some just don't even have the capability). J. -- [ Whatever kind of look you were going for, you missed. ] [ http://www.blackcatnetworks.co.uk/ - IPv6 enabled ADSL/dialup/colo ]

It depends on the make/model of cpu. A quick search revealed this page http://users.erols.com/chare/elec.htm /but/ I don't know how accurate it is.
Currently the CPU is 56 degrees celsius.
Is that under full load? cpuburn is a good way to test your system if you are prepared for it (if you system is not up to scratch then you risk damaging stuff). Thanks Adam -- jabberid = quinophex@jabber.earth.li AFFS || http://www.affs.org.uk/ || Not a filesystem

Thanks, that gives a maximum case temperature for my Athlon of 85 degrees Celsius.
Currently the CPU is 56 degrees celsius.
So I'm probably OK, but a dust out of the heatsink seems to have brought this down to below 50 degrees now. After being on for a while it's sitting at 44 degrees, I expect it'll go up a few degrees more but I seem to have won ten degrees or so by a spring clean. The inside of the case looked perfectly clean but the fins of the heatsink itself were pretty dusty. -- Chris Green (chris@areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

I've found that to make a big difference with my cpu cooler too (Zalman copper flower on an Barton core Athlon XP 2800+) so I try to get in the case every few months and clean it out or just brush the heatsink down each time I have the case open for "fiddling".

Near enough the same processor as I have so maybe the heatsink is similar too. Mine is sitting at a steady 50 degrees now having been on for an hour or more. -- Chris Green (chris@areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."
