Decrease Fan Speed

[leonidas]

I want to reduce my cpu fan speed, my cpu, an AMD duron 1ghz keeps being 55°Celcius, with normal activity (runuing KLite, internet browser, e-Mule NAV & NPF).


So until which CPU temperature should I stop decrease my fan speed?

(I often play games like GTA vice-city & wolfenstein, & watch movies with VideoLan.)

Gee thats a bit high I have an Intel and at this very moment it 25 °Celcius :D

But the more I work it the more it goes up which is normal get a fan with controllor on it some go in the backpain with a small knob which you turn and the "speed goes down,problem with this is your temp goes up !!! I would get the biggest that would fit and one with a low DB say 26/28 that will make it quiet and cooler.

Another option is to fit case fans and if possible one blowing over the processor like I have just rig a bar up then fit it to it I use one of the backpane screws to keep the bar in place.

Here will give you a clue to what I mean http://www.akasa.co.uk/

you might want to get a new cooler and fan. amd are renoun for providing crap heatsinks.

I've done already the two things you're talking about. B)
I have a 19 DB, 8 centimeter fan,& I can decrease until 11DB, that's why I was asking.

[leonidas]

But do you know what is the temperature limit I musn't exceed with my 1 Ghz duron processor ?

[cwctv]

Right got you well according to the chart (can't recall where I found it) its a max 90
Celcius for yours mine is the same cor that extra fan is really working. :lol:

[leonidas]

So I guess I have to set it to 70°Celcius or something? Isn't it? :huh:

But please be sure! I don't wanna blow up my computer :(

If you have already upgraded your heatsink and fan then you should look into adding some case fans. If the temp in your case is high then even the most efficient heatsink will be hard pressed to exchange it's load into the case.

I've been experimenting with my setup and the most improvement came by adding a fan in the top of the case. Most mod sites call this a "blowhole" and it made a difference of about 5C in my CPU temp...

[leonidas]

But that not the problem.
I just want to make my computer the more silent posible

Indeed, I understand.

One way of achieving that goal is to add MORE fans but to run them at a lower speed.
Also to optimise the flow of air through the case.
Think about it...hot air rises. Exhaust that air from the top of the case and you will cool everything more efficiently. At a lower ( hence quieter) fan speed.

[leonidas]

Ah ok I get it! Sorry ;)
I will try this.

But what about the temperature my AMD Duron 1 Ghz CPU must not exceed. How can I know it ? (Is there any internet site where they give the information for each model of CPU?)

And what will be the difference of temperature wether my computer run with the minimum of programs, or the maximum ?

[clocker]

Try googling using the searchwords...AMD Chip Temperature .

You'll get a zillion hits.

Obviously, the more work your processor is performing, the hotter it will run.

[leonidas]

Tanks a lot man!

[Virtualbody1234]

Try not to run the Duron any hotter than 55 or maybe 60 C maximum.

[leonidas]

Really!!

I've just get an AMD documentation which says that the limit for my CPU is 90° Celcius. Isn't 60°c a bit paranoid ?

And when you say 60°C, do you mean that my CPU must never exceed this temperature, or just that it should be the temperature of my CPU when not so much apps or 3D games are running?

Also do I have to care about the main-board temperature ? Mine is at 30°Celcius at the moment.

[leonidas]

*Bump*

[lynx]

Your motherboard temp is fine, but your processor temp is certainly high for normal running, especially with an 8cm fan. The max temp quoted for the Duron chip (90C) is the temp at which it fails, you certainly don't want to get anywhere near that.

You may think that you are only running at two-thirds of the maximum temp, but you are thinking about that on the Celsius scale. If you consider it on the absolute (Kelvin) scale, you are running at a temp of 333K, with the maximum at 363K, so you are already running at over 92% of maximum.

What sort of thermal compound do you have between the heatsink and the processor? Considering your relatively low motherboard temp I don't think that case cooling is a problem and your fan should be big enough to remove heat from the heatsink, so I can only assume that you have poor thermal transfer between the processor and the heatsink.

I strongly suggest you get some arctic silver compound, but make sure you remove ALL the existing compound from the heatsink. If it is a thermal pad, remove as much as possible with your fingernail or a plastic scraper (do NOT use a metal scraper). Then clean the base of the heatsink with a solvent and dry it thoroughly before adding new compound.

[leonidas]

Ok I'll get some artic silver soon. My thermal compound before was wether "Sil-more" or "Zalman thermal grease". I can't remember which one I used. :huh:

1 hour ago, I've decrease my CPU fan speed to the minimum, And hmonitor says the temperature of my CPU keeps being 60.5° Celcius, for 45mn now, with low running.
Can I keep this setting? :huh:

But still something strange:
When I have a look to the performance in "Windows task manager", it says the CPU usage is at 100%. Is that normal ? Idon't think it was like that before. :huh:

:)

No, that IS NOT normal.

A constant 100% usage?

if its system idle prosess its normal&#33;

[leonidas]

I&#39;m goin to restart my computer as it was running at least for 3 day without interruptions, and see if it changes something.

[leonidas]

Done. Now it&#39;s not constantly 100% but it often reaches 100%.

And what about the other point:

Quote/me// 1 hour ago, I&#39;ve decrease my CPU fan speed to the minimum, And hmonitor says the temperature of my CPU keeps being 60.5° Celcius, for 45mn now, with low running.(NAV+NPF+KLite+eMule+Internet browser, inernet connection stuff, & stlye XP)

Knowing that I often play 3D games like GTA vice-city, hitman2, & wolfenstein.

Indeed.

But that&#39;s not what he said, is it?

I don&#39;t know what does this mean.

Is it a (big) problem?

If you run you CPU any hotter than 60C then you reduce its life. So the cooler you can run it the longer it will last (within reason). Also Cooler=More stability.

For the constant 100% usage... Press Ctrl+Alt+Del to launch the Task Manager. Look in the &#39;Processes&#39; tab to find out what is creating the load

my pc stays bout 40C or bout 105F when kazaa is running and im listion to music...that normal??...btw i only have a intake fan and a cpu fan....sorry that sucks but im working on more fans...

40c is fine, if its ur cpu.
