help to see the temp

hei guys..

i want to know that anybody have the same problem with me..

well i'm new with intel P4...

i'm going to overclocking my P4 - 1,6a to may be 2 Gig...
my spec is :

Gigabyte 8irx...
intel P4-1,6a
Temp (bios) 47C
Ram visipro DDR 266 256MB
Generik Heatsink...
VGA pine GF2MX-200
Win98SE

i can push it to 2 gig .. i goes smoothly
but i dont know the temp..
install MBM (the latest) but the speaker (internal)
going "Beep.. beep"...
i cannot eliminate that sound until i restart the comp..
so i back the comp to 1,6 GHz again, because i worried about the temp..

iwant to know the temp on windows 98SE..
without see the bios...

anybody...??
