Two things guys.

After upgrading a 775 motherboard preloaded with a P4 3.2Ghz 800 FSB CPU that suffered from high temp/fan speed in it's original Micro ATX....

I installed into a TT Midi Tower with four fans, new 550W TT power supply, added an 8x AGP Gigabyte Radeon 4650 1 GB video card and 2Gb of 400 DDR Ram.

Sitting on the desktop of office, BIOS reported CPU temp at 49 deg. and low fan speed, nice and quiet.

Relocated into laundry (adjacent to office) on top of cupboards with plenty of free air, but on it's  side.

Question 1.

CPU fan runs intermittently super fast when CPU under load - eg virus scan, CAD program running

Why?, Is it because thing is on it's side?

Question 2

Is there any free CPU Fan / Temp management software I can install that will help manage this?

Question 3

I cannot get the BIOS or Windows XP Home SP3 to report the 2 Gb of RAM. I cannot see anything about DUAL Channel in the BIOS.

What am I missing here.

Thanks and regards,

Give these two utilities a go:

CPU-Z (Cpu, Motherboard, Memory info)

Speedfan (Fan speed)

Thanks for the program links.


Anyone have any thoughts regarding the other issues.

Hi Ragnor

Installed CPUID, and came across this disconcerting information in the HTML version of the CPUID report

Hardware monitor ITE IT87
Voltage 0 1.31 Volts [0x52] (CPU VCORE)
Voltage 1 2.67 Volts [0xA7] (VIN1)
Voltage 2 3.23 Volts [0xCA] (+3.3V)
Voltage 3 4.41 Volts [0xA4] (+5V)
Voltage 4 11.97 Volts [0xBB] (+12V)
**Voltage 5 -5.25 Volts [0x52] (-12V)
**Voltage 6 -10.56 Volts [0xA5] (-5V)
Voltage 7 4.84 Volts [0xB4] (+5V VCCH)
Temperature 0 12?C (53?F) [0xC] (TMPIN0)
Temperature 1 57?C (134?F) [0x39] (TMPIN1)
Temperature 2 40?C (103?F) [0x28] (TMPIN2)
Fan 0 3375 RPM [0x32] (FANIN0)

Are you familiar with this software and what voltages 5 & 6 relate to in the report?

Is it possible that these are transposed by CPUID glitch in software as the brand new power supply came with premade cables that only plug in one way to any device. I'm a bit concerned

Okey Dokey.

Downloaded CPUIDHWMONITOR and now understand better what the other report was showing.

This is what I understand it to mean, CPUID takes an instaneous snp shot, whereas CPUIDHWMONITOR has a realtime running report showing actual versus MIN and MAX

Thus, the snapshot is well within spec.

However, both harddrive temps are at maximum, and any kind of task drives the CPU to max temperature and full speed fan.

Could this be because of the fact I'm now running two lots of DDR400 RAM 1024MB modules?

Also, I upgraded the BIOS prior to installing the second harddrive to version F4. However, both the Graphics card System Information report and the CPUID packages report the BIOS as F3.

Yet on start up, the BIOS reports F4..........

Any suggestions on what might cause this and how I can fix it please?

Hard drive temperature should be relative to how much work they are doing and how good the airflow through the case is. ie: Better air flow through the case, lower temps inside case and thus lower HDD temps.

Not sure why cpuid would report the wrong bios version, might be a quirk with how the program reads the data.

Q1: What make/model motherboard did you have?
Q2: What cooler is used on the P4, just the stock one that came with it?
Q3: Can you post a couple of screenshots of the temps in speedfan while the computer is idle vs under load?
Q4: What make/model is the case?
