Temp & Speed monitoring

[luke]

Anybody familiar with "SpeedFan" monitor configuration?

Its Help is not clear as to what the Nos refer to.

"ASUS PC Probe" shows  
CPU     45c }when using fs9
Mobo   40c }
CPU     27c }when idle
Mobo   32c }

CPU fan speed 3245 rpm dispite 1200rpm set in Bios.
Chipset fan      9375 rpm. !?

My cheap Box has no Fan in yet (waiting for the PC fair).
The CPU that came with the AMD 3500+(2.2ghz) is now 5 months old with little use.

Screenshot shows both Speedfan & ASUS PC Probe monitoring.              Thanx            luke

HOLEY COW!!!! Those case temps are WAAY above what they should be. Clean up the wires inside your case, and think about some more fans, or higher CFM fans. Or even best yet just take off your side panel.

As for your CPU fan speed, is silence really that important that you would rather have your CPU cook? If your CPU heatsink is really that loud you should think about getting a Zalman. Oh and the reason your BIOS setting dosnt work, is because you dont have the correct style of pin selected, that or your board dosnt care enough to bother itself with things like that

Thanx Joyce,
the side panel is off.  And I will be getting a case fan soon.

The cpu fan runs 3245rpm as default I guess.

Would you know how to increase it with this newly found program "SpeedFan"?.

I can not understand it's Help file, and scared to change things.                       luke

Well you just move those little fan speed percent tabs up and down. However I would leave all case fans at 100, and let your motherboard do its own thing with your CPU.

Despite the high Ts & Speeds indicated, the cpu, gfx card and elsewhere on the mobo feel cool on the touch.

I lowered all Ts to 20c & warning 50c and unticked all AUTOs, but still cannot see any figures changing or contrlolling or responding.             luke

Did you set your clock to your correct mobo?

My temps match pretty closely, my chipset fan runs at 5800rpm, to these temps on my Asus A8N SLi Deluxe, but the nforce2 smbus always reads a 126c at both places. I always assumed that these temps read falsely or that they read that high because the program was not monitoring it. Am I wrong?

Brand new computer, all fans working properly, wiring super clean. Nothing seems hot.

Thanks,
Simhead

Well I'm not too firmilliar with Asus board temp sensors. All you really need to do is worry about your CPU heat.

Cheers

Well CT,
now it is configured to A8N Sli Delux and as you can see in this screen shot it is different.

Now on the left shows Zalman @ 3245rpm & the
chipset fan speed is not shown, for some reason.

Yet in config "Speeds" it shows it as "chnl 1".

I asked the maker for help with no result.

see you       luke

Your temps are cool and fine Luke.

The mainboard's BIOS utility won't even kick up the fan speed until the CPU reaches at least 50*.

Cameron is a "mad overclocking type" like myself, and he gets hot flushes when he sees temps on the rise.

Your's are less than average on the stock cooling system and look ideal, so don't worry or change a thing.

The chipset fan is showing me that you have the inferior high speed Asus fan fitted. It WILL SELF DESTRUCT, so plan a replacement now. The chipset gets really hot under that fan, so a real solution is required, the mainboard needs to be removed to replace the fan. Space is tight with several components to get in the way and of course the expansion slots to consider as well. Asus have a replacement part available and they even shipped lots of those to my supplier, expecting trouble, so it was a matter of sending my old one to my supplier which they promptly replaced.

I also used an old P3 HSF unit which I modified by hacksawing the heatsink into shape to fit around the interfering components, that worked well.

Next, I tried to silence my PC's fan noises and tried a Passive chipset cooler from Zalman, it was a disaster and led to immediate high and scary temps. I put an old video card fan on that cooler and it seems adequate

The PC will crash as soon as the chipset gets too hot, and hopefully won't cause damage if the fan fails, but I can tell you, that chip could easily burn your mainboard if the fan fails.

The good thing about the dodgy fan is that the high RPM makes it a screamer when it starts to go, so you will probably hear it before it fails.

In your BIOS, check to see if the Q-FAN CONTROLLER is enabled, that will reduce CPU fan speeds until 51* is reached if you set it that low, (that's the minimum temp, so obviously Asus don't think it's excessive.)

That's all the fan control you need, speedfan is just more junk running in the background.

Thanx a lot Congo,
long time no hear, Honolulu beach I suppose?

Well I saved your terrific old write-up on this and looked it up the other day.

The chipset fan started already screeching and grinding/whining, sometimes on startup.

Talked to suplier last week, alas they do no repairs, so I asked for a replacememt board but they are waiting for them----indefinately! on a long backlock in UK.

The chip has 4 tiny philips screws on top, one each corner. What do they do? Was hoping they held the fan on the chip, but I guess not.

Also on two corners the chip has two spring loaded black buttons thingimigees.

I'll check the Q.Fan cntrlr tonight.         luke

PS after I saw about the chip fan in your old post I said:-

I find that over the years my case fans get noisy as the self-lubricating bearing gets dry.
I prise off the tight-fitting seal from the rear of the fan, squirt a drop of 3-in-one machine oil onto the bearing, and pop the seal back again...!
...Peace and quiet reigns again...for a while... ...!

As to removing the case covers to aid ventilation....
I read, long ago, never to do this because the case ventilation louvres and case fan positions are designed to guide the airflow over the components within the case, in at the front, and out at the back...!
Removing the covers will interrupt the manufacturers designed airflow within the case and may make overheating matters worse... ...!

Hi Paul,
Unfortunately this one is not reparable.

I did not read between the lines when I saw this below, as I was blinded with the writings here that Asus was the best:-

".....chipset fan - this cools the nForce4 SLI chip which is kinda like a northbridge chip. In a nutshell, this fan is a known disaster and Asus are doing their best to replace the defective part worldwide (so the press release states).

[congo]

I don't use cool and quiet and as far as I know, it's not installed on my rig. I don't like any programs running in the background if I can avoid it.

I only use the CPU fan controller "Q-Fan" in BIOS.

The lowest setting in my BIOS for that is 51*C, so I set it there.

This means that the CPU is going to hit 51*C before the fan runs at full speed.

I found that on my A8N-SLI board that my CPU fan gradually spins faster in steps as the temp increases until 51*C when it runs full speed.

A side effect of this is that if a sim is pushing CPU temps up to 51*C the fan kicks in and out constantly as the setting is acting like a thermostat when the fan is capable of reducing the temp below 50* easily. This may not happen on your rig but it does sometimes on mine when ambient temps are conducive.

[luke]

Thanx Congo,
Mine too is 51c lowest & will set it up the full speed to that, & ignore start & stop.

A friend send me this just now, but from what he says it may be another mobo :-

".......I'll have to wait until I get home before I can confirm the exact spec. of my motherboard, however in general terms these chipset/Northbridge chip fans are fairly easy to replace.

As it happens, it was a failure of this
