CPU temp & ASUS Probe

[dug777]

Running my XP2000+ at 2600+, stock cooler, 2 80mm exhaust fans-ASUS probe sez that my CPU is 46'C, M/b is 27'C, but Sandra sez CPU is 56'C, agrees on the m/b temp.

I tried Hwinfo- it agrees with Sandra- using the 'national semiconductor LM75' probe for the CPU- and based on the pretty serious amount of heat i can physically feel touching the CPU cooler i am suspect that Sandra and Hwinfo are talking the right stuff.

I have also read some review that said the ASUS probe usually underreads my 5-8'C degrees- i assume that this is due to the placement of the temp diode beneath the CPU?

Back 2 MY temps tho- currently- according 2 Sandra i hit 64'C cranking d3 or far cry- in spring WA where my room temp probably only hits 22-25'C atm, but when summer really gets going (we had a few days over 40'C last year) my room temps soar well into the 30s. I dont know what sort of temps i'll hit then- but in the experience of you folks who had/have AMD Xps(i'd guess 3/4 of the forum ), what sort of temps should i start 2 worry about? I have heard that the Xps are designed to cope with up to about 85'C- tho for how long i dont really want 2 know

(sorry if this is a thread that has been started a zillion times...please don't flame me 2 hard )

please?

there is a question in there

i think that the asusprobe and any other programs use the same sensors to give you the temp, because i'm pretty sure those are the only ones there are for the cpu. it's probly just the asusprobe algorithm is off, or the other way around. there's no way to really tell other than to use one of those infrared temp sensors on the core itself, which i don't think you can do with the heatsink on there

General consensus is to trust the temperature readings given in the bios. Granted, reading the bios temp under load situations in windows is currently (to my knowledge) an impossibility with readily available, readily affordable tools.

I like to play things safe. I run an ASUS board with a Barton 2500. I set the bios temperature cut-off to 70C for the cpu. A properly built, properly cooled system should never see those temperatures anyway regardless of load conditions. For me, I don't like to see my CPU temps get much above 50C, but then I've already admitted that I tend to be conservative. Even in high ambient room temperatures, good cooling and proper airflow through the case helps considerably. My suggestion would be to look into purchasing good high flow case fans and an aftermarket heatsink.

P.S. If you choose to replace the heatsink, carefully remove ALL the old grease from the die and use new, high quality heatsink grease. The CPU die should be completely free of old grease and oils before installing the new heatsink. Improving cooling isn't expensive! You should be able to add/upgrade case fans and heatsink for well under $50.00. Consider any cooling improvements an added insurance policy toward extending the life of your system.

cheers for the feedback- it just seems strange 2 me that my asus probe is so far out- or certainly seems 2 be. I have set my bios shutdown 2 70'C as well- but have never had it shutdown- has this ever actually happened 2 someone? -as far as i know my bios readings r good- they agree with the sandra and hwinfo readings-at idle?

Ne way, ne further feedback would be appreciated, cheers folks

sorry- that 1st edit screwed up- i am in oz- western australia- and it certainly seeeme we r some way behind the US and EU when it comes 2 hardware prices and availiabilility

Are you having heat related system problems or are you concerned over the accuracy of your ASUS probe? Heat related problems like sudden unexpected shutdowns/reboots and/or screen freezes will frequently show themselves BEFORE you reach your motherboard cut-off temperature. I've never had a system shut down due to heat that I've built. However, I've seen and heard about it from others. Usual culprit is someone doing something stupid, a dust and animal hair clogged heat sink, or a failed cpu fan.

If your system is running fine yet you're concerned about temperatures during the hot season, install an intake fan in the front of your case and an exhaust fan in the back. This isn't advanced hardware and you should readily be able to find them at your local computer shop. Also, if you're far away from the nearest shop, you can make your own out of old heat sink fans. There is another good reason for using both an intake and exhaust fan other than heat build-up. The air moving through the system doesn't allow for nearly the dirt/dust/animal hair build-up that collects inside the box. That debris acts as a heat insulator and will cut component life. Clean, cool boxes with good airflow will last a long long time!

I have a question.

AsusProbe is measuring a 41C idle temp on my overclocked Winchester (250x10 on a 3200+). But Everest is reading only 29C! How could these two be getting such different temps??
