Temperature Discrepancy between Sandra and Motherboard Monitor

[shurato]

First of all i am wondering if i even set up mobo monitor up correctly. I have a duron 600@950 1.75v on an Abit KT-7. I set the 3 temperature sensors to the corresponding VIA 686A sensors. Its reading 22 27 47 right now. Am i to assume that the last number is the CPU? Sandra reads 39c constantly. I am running prime95 right now on the torture test. I know that the temperatures on sandra are inaccurate but can it be that drastic? When i wasnt running prime95, mobo monitor was reading 44c at idle. I am quite dissapointed as last nite i added a FOP32-1 with artic silver as well as replaced the front intake fan with a sunon 80mm high output and a sunon 80mm for the exhaust. This is in an INWIN Q500 full tower. What temperatures do you think I should be getting or could be getting with my setup? IDLE and FULL LOAD.


p.s. is putting prime95 in the torture test mode considered full load?

my MBM-5 says 23C, 35C, 34C for the same set up as u. while sandra says 60C. NOW thats a discrepency.

my thunderbird is supposably at 70c according to sandra. of course it shows my memory at 150mhz, my agp at 4x100mhz, and pci at 50mhz, no wonder its so hot =p

I would trust MBM over sandra anyday.

Which MB bios are running? Also, assuming that 22C is your case Ambient temp, your CPU would be running, at best, at 44C(core temp/full load, prime95 is fine for checking full load temp). Also, don't worry about trying to read idle temps, cause of socket A temp inaccuracies. Theoretically, your idle temp will be roughly 8-10C lower than your full load core temp.

Try reapplying Artic silver in a little bit thicker layer. Several bbs members have had more success with a thicker rather than thinner layer.

MY bios serial number is 08/25/2000-8363-686A-6A6LMA19C-UL ...im guessing that the bios identification? Motherboard Monitor reads 22 27 44 on the average when im doing fairly light work as im doing now...have a MIRC session open, outlook 2000 and browsing one webpage. Is that good? I'd really like to hit for the upper 30's if possible. But as long as im in the average I guess I can be content. Also i am weary of re-applying the artic silver...i almost had a heartattack trying to place the fop32-1 with the artic silver the first time around. Also....if i do re-apply...do i just add some more to the HSF? or do i have to clean off the current amount and add a bigger amount than the previous...

Apply grease to the cpu core, not the heatsink. Especially with AS.

Clean off all leftoever grease with rubbing alcohol, then apply a semi-thick/thin(somewhere in between, but not semi-transparent) layer on hte cpu core. Try to make the layer of grease fairly even. Then reattach the heatsink.

Your temps right now are fine, and you're running the UL(latest, i think) bios. So it includes the auto-compensation for cpu temp.
