CPU Fan at 3444RPM!

Hi, i've been trying to find out what is causing my cpu fan to go at 3444RPM! but still i dont have a clue. the cpu temp is at about 55-60 degrees celcius, which is good ( i think!) but the cpu fan is extremely LOUD.

my cpu fan is the default one sent with my P4 3.2GHz processor

Oh! another thing, a few weeks ago, my cpu was at 74 degress celcius at one time, so i switched it off, and replaced the thermal wax between the cpu and the fan with the Artic Silver 5 Thermal paste. This has made it go cooler but still the fan has to run so fast!

Any ideas?

**EDIT** Hey just fund out that my cpu is overclocked......i think....i have everest ultimate edition, which displays overclocking info.....and it says that my cpu clock is 3217.5 MHz (Original : 3200MHz)

does that mean it's overclocked?? if so, how can turn it down, so that my cpu doesnt run as fast???

Thanks

The 17MHz difference in CPU clock can easily be accounted for by normal slight motheboard variations, it isn't enough over to be concernbed about at all.

Only a very few motherboards will control the fan speed, most just run the CPU at maximum. The only thing you can do if you find the noise too much is to get a different heatsink and fan unit.

an overclock like that is nothing, thats a half percent, you may not even be able to control is that much..

3444RPM isn't really that high.., least I wouldn't think so, what is the last computer you used? this generation of computers have loud fans..; are you sure its the CPU fan?;
does the fans that come with the P4's actually change RPM when the temp is higher or lower?, it could just be that it stays at that RPM...

in everest can you also get the CPU multiplier and the CPU FSB speed?

I've ordered the zalman super flower silent cpu fan (cnps9500), so hopefully that will reduce the noise.

Also, when monitoring the cpu fan using everest, the fan's RPM ranges from 1975RPM to 3500RPM, things like playing games, downloading, streaming media will cause the fan to spin even faster, but that didnt happen when i first built the computer.

9500? where did you find that at?

Its at a few UK sites, its supposed to be officially released today, but some online retailers are expecting stock on 26th August, so i'm guessing Channy will be waiting a week for it.

whoa, I just looked up that thing.., I am definately getting one.., I mean.., I was gonna get the 120mm all copper one they have (7700?) but this thing sound great.., definately worth the extra $30..

only problem is now i have to wait.., but it looks like its gonna be worth it
overclocking with that thing shouldn't be a problem :D
I wonder who thought of the pipes going up like that, its got to be much, much better to have where the air can actually go all the way through the heatsink
maybe soon they'll have a mini one for VGA, that'd be cool

It should be in the Pipeline.......sorry that was a bad joke.:)


Have you seen the pictures of the display model from some event before it was due for release, its huge!, they made a huge replica (i think its a replica) and put two normal sized versions either side:

You may find that there is a setring in the BIOS to disable the variable fan speeed, so that it runs at full speed all the time. I know that some people find the variable speed very distracting.

the thing is huge, not as huge as that replica, but-

I wonder why they don't put two fans on it, I guess that'd be a bit louder, but still, it could easily be done


what are these?
what is the difference between these and the all copper ones they have now? red paint?

hmm.., and what is this?

and this?

Tt rip off? I wonder if I am suppost to be looking at these pictures, there is alot of Tt stuff here.., heh.

now I really wonder if I am suppost to be looking at these.., images 53 through 57 are pictures of some really kawaii asian chicks at certain stands :D:D

Those red ones are just painted copper, and the ones that don't look like Zalman are "Copycat" examples, see this link: http://www.zalmanusa.com/usa/pr/ad_v...?idx=34&page=1

You can view the pics, i think you just found a different door into them.

you'd be right..

I wonder if that would fit in my '65 Lincoln? :eek:

the fan is running fast because the cpu is hot. i don't know how hot a 3.2ghz p4 should normally run, but 60°c sounds a bit too high. according to my resources, they have an upper thermal limit of about 70°c.

Is your case air flow allowing enough (or forcing enough) outside air through the case? If the air is just recirculating for the most part inside the case instead of being exhausted, the CPU fan will just be moving hotter air. This is straight from Intel, page 82. Here's the whole deal:

http://support.intel.com/design/pent...s/29864312.pdf


"7.4.1 Boxed Processor Cooling Requirements
The boxed processor may be directly cooled with a fan heatsink. However, meeting the processor's
temperature specification is also a function of the thermal design of the entire system, and is
ultimately the responsibility of the system integrator. The processor temperature specification is
found in Chapter 5. The boxed processor fan heatsink is able to keep the processor temperature
within the specifications (see Table 5-1) in chassis that provide good thermal management. For the
boxed processor fan heatsink to operate properly, it is critical that the airflow provided to the fan
heatsink be unimpeded. Airflow is into the center and out of the sides of the fan heatsink. Airspace
is required around the fan to ensure that the airflow through the fan heatsink is not blocked.
Blocking the airflow to the fan heatsink reduces the cooling efficiency and decreases fan life.
Figure 7-6 and Figure 7-7 illustrate an acceptable airspace clearance for the fan heatsink. The air
temperature entering the fan should be kept below 40 °C. Again, meeting the processor's
temperature specification is the responsibility of the system integrator."

hey sorry for the late reply, but i've tried:

1) replacing the thermal paste (again!) with artic silver 5
2) turning my two 80mm fans around so that it was blowing in air from the outside
3) turning the CPU fan speed control on and off, to see difference

But, nothings worked......i turned on my computer, left it doing nothing for 30mins, looked at the temperature with everest and it displays my cpu temp at 63c! and my cpu fan going at 3125RPM!

Somethings definatly wrong.......I even tried starting it in safe mode, with little processes.....but still the same temp and fan speed

any solutions?

My feeling is that Everest is not reading the sensors properly, or that the sensors are faulty. Is the computer showing any symptoms of overheating at all? Things like slowing down, locking up or shutting down by itself?

there are times when the computer just suddenly freezes.

But yesterday i managed to take my case apart, clean out the dust and turn the front fan around. So that my two rear fans blow outside air into the case and my front fan blows the air out.

That calmed my computer down to an average of 51c when not doing anything on the computer. Hopefully my New CPU fan should arrive next week! So my computer should a nice "quiet" change

Well that's certainly an unusual way of doing it, but as long as it works OK that's the main thing. Thanks for posting back and letting us know :)
