High temps?

[KT8]

I recently changed my motherboard from an Abit KG7 to a Abit KV7. With that my case & CPU temp both went up by 10~12 Celsius. With general use the CPU is at 48 and the case 55, and that's after buying some arctic silver 5, which did knock a couple of degrees off.

The root cause I think is the increase in case temperature, but could the motherboard alone be responsible for that?

The temps don't seem to be affecting anything, stability is excellent, but I would like to get them down a bit.

Spec:
Abit KV7 motherboard
XP1900+ CPU (Cooled with a Zalman Flower Cooler)
80GB WD Hard drive
Nvidia GeForce 4 Ti4800SE Graphice
DVD & CD-RW
Audigy Platinum Sound
Aopen Midi tower Case & PSU
1 intake & 1 exhaust fan.

Any suggestions?

well, it could be a few things.


those onboard temp probes on mobos are not very accurate.
i think this one is off a little.

another thing i would look for is the voltages. vcore/vdimm.
maybe this mobo is giving the cpu/mem more juice than the other motherboard.

Exactly what citrix said! The only factor is the mobo, whether it is more voltage or the onboard temp probes, check for bios upgrades official and unofficial.

I've updated the BIOS, no change. Settings are as follows:

In soft menu setup:
CPU Core: 1.850v
DDR: 2.65

In PC Health they are:
CPU Core: 1.77v
DDR: 2.68v

Everything is at default settings, do these look OK?

ur voltage on ur cpu is a little up i'd say, my xp2000+ runs at 1.632v for default(says cpu-z), unless u oc'ed ur processer and raised voltage for stability.

I would agree with citrixmeta, however the voltages do see a little high as SSR_06 mentioned, maybe the default on the new mobo wasn't correct and you should lower it?

Personally if it's stable I don't worry about the temperature too much. If the 1900+ is a Palomino core it's probably going to get pretty toasty regardless. My good ole tbird idles at 45-47C. :)

do you have a seprate senors you can use like a front bay temp reader?
