My cooling fan speed decreased to a lower speed. How do I speed it up??

Currently, it's:

CPU: 4821 RPM
Chassis: 993 RPM

In the old time, it's:

CPU 4963 rpm
Chassis 2482 rpm

I tried to change in the BIOS but i see no options of it.

My cpu used to be lower at 35 Celsius and now it's at 49 Celsius.

Take a look at SpeedFan and see if it fits your needs.

I downloaded it. I see the speed of the cooling fan was been reduced to 50%. I try to increase it to 100% but nothing is happening. What should I do next?

My computer CPU is currently in constant overheat (120 F or 49 C)

What makes you think that 49 Celsius...indicates overheating for a CPU?

System manufacturer and model?

What CPU are we referring to?

Perhaps your fan/heatsink...need to be replaced.

Speedfan. At 50 Celsius it has an overheat icon and this is when I only use the internet. If I use other application, it rise up to 56 celsius.

I'm reffering to my cooling fan cpu (not the default motherboard fan). It's currently at 993 RPM and I want it to be back at 2500 RPM.
I simply want to change it back.

OS Name Microsoft Windows XP Professional
Version 5.1.2600 Service Pack 3 Build 2600
BIOS Version/Date Phoenix Technologies, LTD 6.00 PG, 8/24/2005
BIOS type: Award (08/24/05)

The cooling fan "chassis" and The "CPU" one is the one from motherboard.

In speedfan, at speed02, it's at 50%

I am not the one who installed the cooling fan years ago. It was my tech.. he managed to put the cooling fan speed at 2500 RPM.

how can i know the brand and model? is it Windbond W83627EHF ?
why would you want to know?

All I want is to set back his speed back to 2500 rpm through the BIOS but I dont know how and where.
I can't find!

Is it possible to change cooling fan speed throught command prompt?

Why do you believe that the 'chassis' fan is the CPU cooler and not the actual chassis fan?

Also, when was the fan last working properly? How did you discern a change? What has happened to the computer during that time?

We need quite a bit more information before we can answer you properly. Also, be aware that modern CPUs can handle 50C just fine. Don't get me wrong, it is a little high, but not something to burn down the house over.

If it looks like I know what I'm doing, there's a pretty good chance the only reason for that is because
I once asked someone to run chkdsk /r and a BC Advisor smacked me in the back of the head.

Because it's not the system fan.

2-3 days ago it works fine. My hard drive disconnected. I tried to replug and switch sata port, but my BIOS reset (date set back to 2005). Fan RPM has slow down.

Also, be aware that modern CPUs can handle 50C just fine.

Sorry but 50 C when I'm not opening browsers or anything is too high for me. When I play game, CPU fan speed doesnt even increase.

Does this mean then that the CPU fan is not plugged into the appropriate CPU fan header? Because otherwise this isn't making any sense.

It may be that I am just inexperienced, but I'm not aware of any circumstance where plugging in a hard drive causes the BIOS to lose battery backup. For all I know you might have EMP'd your motherboard with your hands. I think I'll bow out and leave this to a guru stronger than myself.

What does EMP'd mean?

The fan is well installed. It was installed by the tech.

Static electrical shock. If you don't even out your body's charge with that of the computer by touching a metal part of it first, the difference (sometimes thousands of volts) will discharge into the electronics you first brush against.
