I installed the ASUS PC Probe and the Power Fan Threshold & 3

[cantgiveup]

Chassis Fan Threshold is set at the default of 1200 rpm. I'm getting clicking noise telling me the Power Fan and Chassis are 0 and the Monitor Summary for both of these the Value is 0 and it's blinking with the words (Power Fan below threshold!!! for both. I'm using Windows ME and I have the AMD Athlon 2100 CPU

Turn off monitoring of the psu power fan .
For that one to work as monitored the psu
must supply a cable from the buildt in fan and it has to be connected to the motherboards pwr_fan connector.

I've seen this with asus before that they dont always support low rpm fans .
Lower the threshold for the chassis fan below 1200 .
Or perhaps you have two case fans connected with an y-split
to tha motherboards cha_fan connector . Or are they
connected directly to the cables from the psu (in that case
their rpm can't be monitored)

I just went in the Bios and under Hardware monitor The Chassis Fan and Power Fan Speed is set at 0 RPM I don't see any place to change these settings and did change the RPM in the PC Probe software but I'm still getting the same ticking sound like a clock with the same messages.

 

[cantgiveup]

I did install one case fan on the back of the case not far from the CPU and just connected the wires directly to the PWR Fan one. I can't set the threshold for the chassis below the 1200 as that's the lowest it will go. When I first installed the ASUS PC Probe neither the Power Fan or Chassis Fan had a check by them but everything else did, so I put the check by both as I thought they should be monitored also.

cantgiveup !
(nice handle by the way , it fits your posts today..)

1.
Are any of the case fans connected directly to the motherboard .3-pin connector near the video card named cha_fan1 .

2.
Does your powersupply support fan monitoring(many don't support this).
If its supported there is a cable coming from the psu
like the fan cables .This is to be connected to the motherboard on the other 3-pin connector next to the cha_fan1 and it's called pwr_fan1 .

In my own pc the psu don't support fan monitoring so i have used tha pwr_fan connector on the motherboard
for a case fan # 2 (you might also do that ) .

Anyway if all your case fans are spinning it's not a big deal with monitoring . The important one to monitor is the cpu-fan and temperatures .

Syar, you see I've been teaching myself and have never went to school or anything as I'm sure you can tell lol This is one of the reasons why I'm asking so many ?'s and from all the great answers it seems everyone else must have went to school? or just very very smart.

Yes the 3 Pin Connector from the Case Fan I installed in the back of the case is plugged into the Pwr_fan 1I don't have anything plugged into the Cha_fan1 but it's right next to the Pwr_fan1 I only have the one Fan plugged in right now but was thinking of putting another fan in the very front of the computer case thinking it might be a good idea.

I'm not sure if the Powersupply supports fan monitoring. Can you tell me how to check and see if it does? The other thing is the CPU Fan Temperature the Value is 4623 and changes a little bit and it says the Status is Ok but the thing is I still think the computer is noisier than it should be.

 

[SYAR2003]

If the powersupply supports monitoring you should se a cable coming from it that looks like the cables from the
case fan but it only has two wires .
And it should be some printed marking on it .
If this comp is new buildt , i'm sure you have some papers/manual of the case and psu assembly .
Anyway it's not that important if you gonna use the
last mobo connector for a new case fan .

The asus q-fan dont kick in i guess because of
the cpu temperature is so high it wont slow down the fan .

You have some options:
Keep the TT6 heatsink and try to fit a 80mm fan on it .
Move the case fan you now has in the back to low front
and let (for now) the psu work as the exhaust fan .
This will bring airflow passing the cpu area and hopefully
reduse it's temperature .
Use the last fan connector later for a dedicated
exhaust fan in the back .

But right now move the back case fan to be a front fan instead , make sure that it sucks air into the cabinet .

I hate to disagree with Syar, but I wouldn't remove the rear fan you just installed unless your power supply has a grill on its bottom, above the CPU, that'll draw the CPU heat away and out of the back of the supply.

This is AMD's position on cooling:

http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/cooling_guide.pdf

How many wires are in the connector from the fan you installed and connector to Pwr_fan1? If there are three, then you should not be getting a reading of 0 from the Power Fan in AsusProbe.

 

[SYAR2003]

Freestone please !
What kind of airflow do you have in a cabinet like his
is right now ,no fresh air is coming in .

All new psu i have seen has grill openings ,
how else can the psu components be cooled .

All PC setups with one case fan has it in the front ,
and the psu exhaust acts as case exhaust .

I purchased this ATX Case from a small computer business that who was going out of business so there were no papers with it. The power supply however was included with the Case which is 350W but the grill opening is on the side where the power supply wires come out and not on the bottom. I have another Chassis 80 MM Fan (Ball Bearing w/3-PIN MOLEX with the white extensions or whatever they are called that I can put in the front of the case as there is plenty of room for it and that way I would have 2 case fans one in the back and one in the front.

 

[cantgiveup]

Freestone, there are 3 wires coming from the case fan Red, Yellow and Black, but I'm still getting 0 from the Power Fan and Chassis Fan and as I was saying in the BIOS it is showing 0 for either one of them also.

 

[Freestone]

Syar,

If you look at AMD's diagram, you'll see that they want power supplies to have a grill on the bottom, in addition to the front. I never said anything about a supply with no openings, please. Without intake from the bottom, your AMD's CPU heat isn't going to be drawn away sufficiently. I happen to agree that a front fan is needed, but unless you have a bottom grill in the power supply, you also need a rear exhaust fan.

 

[Freestone]

Move the connection off the power fan connector to the chassis fan connector. You should get a non-zero reading as you have three wires, 1 for +12V, 1 for ground, and the last for rotational detection.

 

[SYAR2003]

Freestone i agree with that grill thing.
If cangiveup's psu only has grilles on the side
and it's a mini or midi cabinet the cpu&sink is
lightly to be caught in a warm dead sone .
But when having another fan already , make use of it
and put that one in the front .
Then lets see how/if the wonderful asus q-fan tecknology will work , hehe .

Anyway i would go for having a 80mm fan on the
cpu heatsink as they push the same amount of air as a 60mm
at lower speed .Reducing the noice with upto 10db maybe.

[Freestone]

I'm relieved we are in agreement, Syar! Yes, use the fan on hand in the front.

 

[cantgiveup]

You guys or gals are absolutely wonderful. Thank you so much!! I'll let you know tomorrow how and if it works.

 

[SYAR2003]

I'm a 42 year old "guy" and please post back how it goes "cantgiveup"

I can see by reading the above that there was a little dispute about where one extra case fan is more effective.
I have to agree with Freestone on this one and say if you have a standard single fan power supply , which only has cut vents internally at the rear, fitting a single fan to the top rear (exhausting) is nearly always more effective than fitting the same fan (sucking in air) at the lower front mounting point.
This is my own tried and tested opinion and AMD's own advice (which freestone pointed out) a negative pressure effect does take place and cool air is drawn from the places of less resistance, which would be the lower front vents and generally anywhere that has gaps.
This method doesn't supply a particularly directed air flow but is the best solution in a standard midi case with standard PSU and one extra fan.
Fitting a further fan to the lower front reduces the air pressure imballance and gives better direction to the air flow and is obviosly more effective overall.
One last point the fitting of a two fan power supply is also very beneficial, the second internal fan draws warm air directly from the CPU area and is very worth while and generally can knock a further 3-4 degrees C
of the CPU temps.
I agree fitting a 80 to 60mm step down fan mount on the thermaltake 6 will quiet it down and still keep it fairly efficient (Acasa and others make metal or plastic versions)

Replying helps further our knowledge, without comment leaves us wondering.

 

[SYAR2003]

Yes paparazi as i posted before i agree .
And just that you se my comment correctly :

Move the case fan you now has in the back to low front
and let (for now) the psu work as the exhaust fan .


"For now" don't mean permanently but temporary
until a second fan was in hand .
And i agreed that is was not a good idea since
the psu was closed in the bottom .

thanks

Hi,
I plugged the chassis fan in the back to the cha_fan1, then installed a second fan in the lower front. The Settings for the CPU Fan , Power Fan and Chassis Fan Threshold are all set by default at 1200 rpm. I'm still getting the same reading for the CPU which is 4623 but the Setting for CPU Temperature Threshold is set at by default at 72 C CPU Temperature Polling Interval is set at 5 sec. I'm not quite sure what you mean by installing a bigger fan on the heatsink, do you mean take the thermaltake volcano 6cu fan off and install a 80 MM fan? I'm not sure how I would do that since the 80 MM fan is quite a bit bigger. I'm now wondering if I should be changing the settings on anything inside ASUS PC Probe program?
