| | CPU fan doesn't run during boot-up
I recently bought myself the parts for my new computer (INTEL Pentium4
531 boxed, 2x512 DDR2 533MHz Kingmax, GIGABYTE GA-945PL-S3 I945PL mobo,
ASUS EAX1300PRO-SILENT/TD/256M video card, Hiper Power HPU-3S350 350W
power source) and put it together. At the very first boot-up sequence
everything ran as it was supposed to (got Windows XP SP2 installed in
under 15 minutes). This is my first super computer and needless to say
I was over-excited. Anyway, before installing Windows I went through
the usual setting up of the BIOS. I enabled the "CPU fan failure"
signal beep, also "Smart CPU fan mode" (whatever that was), booted up
from the CD-ROM and installed WinXP. I spent the rest of the day
installing software and games and all went smooth.
The surprise came the next day, when I got back from work and hit the
power button on my computer case. I got the CPU fan failure beep !!!
(which is quite annoying). I immediately hit the power button, opened
up the case and with my eyes on the CPU fan, hit the power button
again. The fan stayed motionless. I even tried to give it a boost
manually, but nothing happened (the CPU fan failure beep was creeping
me out). Again I turned it off, turned it on, entered BIOS, disabled
"Smart CPU fan mode" and continued to normal boot-up sequence. To my
surprise, no more CPU fan failure beep. I continued on playing Quake 4
for the rest of the day and all was okay. Until the next day... when I
got the CPU fan failure beep AGAIN. I entered BIOS, went to "PC health
status" section, 0 RPM for the CPU fan, about 12 centigrades for the
CPU itself (which was slowly and constantly rising about 1 centigrade
every 2 seconds) and I disabled the "CPU fan failure"signal beep (still
0 RPM for the CPU fan). Saved the changes, restarted the computer (no
more CPU fan failure beep), entered BIOS, went to "PC health status"
section: about 19 centigrades for the CPU, still 0 RPM for the CPU fan.
I waited a bit and to my surprise, when the CPU hit 21 centigrades, the
fan started rolling, at first at 1600 RPM, then a little faster. I
restarted again and went on with the usual stuff.
After this, each time I boot-up for the first time, I first enter BIOS,
watch the CPU heat up from 10 to 21 centigrades and the CPU fan go from
0 to 1600 RPM the instant the CPU hits 20-21 centigrades. I still have
"CPU fan failure" signal beep and "Smart CPU fan mode" both disabled.
Has anyone ever had a problem similar to mine ?
Is it that INTEL has implemented some new technology (something like
AMD's "Cool and quiet") on its new chipsets, some that I haven't heard
of (and I consider myself to know pretty much everything INTEL cooks
up--in case you haven't figured it out by now, I am an INTEL fan) OR I
really need to get a new cooler for my CPU ?
ANY help/suggestions greatly appreciated.
