Fans don't stop even on Idle, HELP !

I tried to install a driver for my wireless adapter, but my laptop completely froze during that, couldn't do anything. So I turned off the notebook via the power button and restarted it. It started with the fans flowing like in load mode, now my temps are ~40 degrees on CPU and ~45 on GPU, and the fans run very loud, usually i can't even hear them on this temps, what's wrong? Is it safe even now to write on the internet while they are running like that?

 

Have you tried turning it off and on again?

 

Yes, 2 times

 

Is it dangerous if it runs like this constantly? Is there any program that monitories the speed of the fans?

 

Oh it just got back to normal few minutes ago, pfew, but what was that ?! I thought it was going to blow up.

 

Cornish pixies maybe?


Anyway, I assume you've checked the vents for blockage? Not to mention keeping it cool.

 

Better they run at high speed than not at all. Keep the vents clean.

 

I had a similar problem at start-up for a while after downloading some updates. After a few day, the problem vanished as suddenly as it appeared.

 

calm down first.. second follow my guide below to making ur dv5 run cool and have the fans turn on only in gaming..

1. Undervolt using the undervolting guide..
2. get the 195.62 NVDIA driver and use the following riva tuner tweak to allow GPU to downclock with no problems.. it seems to have made my fans very silent..

3. Get a notebook cooling pad..

My Dv5t runs so cool that i OC GPU

 

1. Already done that, it helped significantly
2. I will try it tomorrow, I hope that guide is pretty detailed as I am not familiar with overclocking tools at all
3. Already got one, and it was a BIG mistake! Why? Cause dv5 overheating issues are because their heatsinks are under the notebook, so when you keep it on a table or even a cooling pad, the air doesn't get out efficiently, so it overheats. So I rised the laptop a few inches from the table with some low value coins on each of the 4 corners, and the overall temperatures went down with ~10 degrees, on both CPU and GPU. Believe me I tested, and the cooling pad isn't as efficient as the method I just told you about. Instead, I use the cooling pad on the keyboard, contrarily if you know what I mean, with the air ventilation going downwards. That didn't have such a big impact, but the temps decreased with 2 more degrees on the CPU. I suggest you try, and you will notice that your laptop will run even cooler! You can also google dv5 overheating problem to convince yourself.


Back on topic:
Regarding my problem, it happened againt just a few hours ago. You see, I run RMclock to undervolt my CPU. This utility also shows the GHz your CPU is running at, along with the temps and some other things. Usually my CPU is running at 1.60 GHz on idle, but when the fan problem occurs, the CPU is running at the full speed of 2.4 GHz. Also the notebook is running hard, the performance is decreased, like it has a lot of multitasks opened. On task manager and processes, a lot of proceses eat 10-15 of my CPU, mostly explorer and System Idle. So this problem seems to be from the CPU, not the fans. Anyone know what this could happen? This problem occurs when I turn on the laptop, but only sometimes, and it ends after ~10 minutes (max).

 

The BIOS didn't like your updates. The BIOS has full fan control, and when something messes with the sensors (temperature or otherwise) it sets the fans at the highest settings, so as to protect the hardware because It doesn't know if the information it's getting from the sensors is accurate ATM. After a while (like you said) it will return to normal, after it keeps getting normal reports from sensors.

 

it could mean ur undervolt is not working... if ur undervolt doesn't work , the stress might cause the temps to be high... see also if u have crap processes.. i get rid off them clicking on manage and services and getting rid off the crap ones..

 

I don't really know which of the processes are crap, so I can't risk to close anything system related. The undervolt is fine, I ran the orthos stress application for 8 hours (a whole night) without problems at the limit voltage (if I get any lower I get BSOD), since a few months, so it shouldn't be from that.
About system update, I haven't updated my windows since 2 months if I'm not wrong, so it's definitely not that. Only thing that comes in my mind would be the "Advanced system care" application, a program that automatically removes spyware, fixes registry, sweeps any privacy files left from browsing and cleans junk files if there are any. When I said automatically I meant when I'm Idle, as the process takes 1-3 minutes. I'm suspicious about this program because since I have it on my desktop as well, I can't shut it down from the start button (the desktop). So I have to use some other method and I'm lazy to reinstall OS ATM.

 

What exactly is the name of this advanced system care application?

If it's http://www.iobit.com/advancedwindowscareper.html, it's probably fine.

 

Yep, it's that one.

 

It happens again, this time the temps are perfectly fine as you can see in the picture taken. What is the problem? How can I fix it? The fans are very loud.
A strange thing i just also noticed, is that if I unplug the notebook and use it on battery, the fans stop, even on high performance power plan.

 

bump......

 

Have you tried resetting all BIOS settings, or looking for an option like fans running on AC?

Also, is Speedstep enabled>?

 

I don't have any idea how to do any of those

 

Google it...

Beats me how to get into your laptop's BIOS.

Maybe one of these: http://forum.notebookreview.com/hp-compaq-voodoo-pc/306466-hp-dv5-bios-key.html

 

go to the hp drivers site and update to latest BIOS and drivers first..

 

All HP laptops have a "Fan Always On" option in the BIOS. Your fans might be clogged enough to make them loud but not enough to make them not work. Try blowing some compressed air into the vent.
