CPU overclocking & heat

[Benjamin Hall]

If you look at my system specs you will see my CPU.
My max core temps are about 200*F. On a stead idle, my CPU should only be going around 100-115*F. Well, last night, having my chill mat, and usb hub plugged in (with a usb monitor and portable hard drive plugged into the hub) my CPU was at 183*F, and I'm really wondering why.. and now, even at an idle, it runs about 138-155*F, and I'm just trying to figure out why... does anyone know what might be going on?

Yes, I know I need a new laptop, but that's out of my budget..

 

[Lordbob75]

Can you put that in C? No one measures those temps in F.

How do you know what your Idle temps should be?

~Lordbob

 

[Benjamin Hall]

Because that's what it used to idle at...

So, in C...

it has a max of 90*C
It should idle around 46*C
Last night it was at 84*C
Tonight it's at 67*C

On my *first* DV9000, the processor overheated, and stayed hotter than normal, leading to a system failure. This may or may not be your case, but is what happened in mine, though I hit around 130C on the core temp. Also, on the DV series notebooks, the fan is almost directly connected to the processor heatsink, and excessive heat on the heatsink could have screwed up your fan. What's the RPM at?

 

[Benjamin Hall]

How do I view the RPM's??? Though my fan does seem to work well, since last night it was whistling away like a siren.

 

[LiquidSnak]

If there is no built in program, then something like hwmonitor or speedfan will tell you, I believe.

 

[Benjamin Hall]

Not sure... task manager, speedfan, and hwmonitor all don't show my fan speeds.. I know my fan works because it runs quite a bit. I am just unable to view the speeds.

 

[LiquidSnak]

It might not be hooked up that way. If it's working properly as far as you can tell, we've reached the end of my technical knowledge and I will have to pass the torch. How old is the notebook, by the way?

Don't know of any other programs to suggest, but have you tried blowing out the ports with canned compresed air? Laptops especially older ones tend to have a great deal of build up of fibers and dust due to user using them on their laps or other cloth or fiber surfaces.
I'm pretty sure if you were to take it apart you would be amazed at how much dust ect is built up inside of it.

[LiquidSnak]

Good advice too.

If your room temp is around 28C then idling (0-10%) temp should be 40-50C on hard surface. Usually without a cooler load temps on my laptop go up to 95C, and thats hot. If i use a cooler it remains within 70-80C.
And in case your minimum processor usage is not 0%, you can go to power options, advance power options, processor power management, minimum processor state, and set it to 0%. Try cleaning the interior of your laptop if your willing to taking the risk.

Laptops generally run hotter than desktops, but a well designed laptop on a chill mat will seldom go over 60c core temps, and never over 80c. Newer DV-4 laptops all run extremely hot, even compared to other HPs. On one DV-4 I've seen this year, the fan didn't switch to full speed until core temps were over 80c. If you haven't already done so, reinstall windows from a clean disk to eliminate software and driver conflicts from all the factory bloat. There's a bios update that reprograms the fan controller for some dv4 models.. other than that..It's just a badly designed machine, not much you can do

Sounds like time to open it up and see how deep you can clean, air, old tooth brush and some q-tips help, with luck you can get close to the fan then clean its blades very carefully with slightly moist q-tips and then with clean dry one. Let everything sit and fully dry if any moisture was used, reassemble and air flow should be much enhanced. It's always amazing to me how the build up of dirt on the fan blades impact performance and air just doesn't get it. Good luck and cleaning will help and don't open beyond your comfort level. Coolers that don't elevate the laptop to allow air flow are a waste of time in my opinion if they elevate and had added fans mo betta !
Good Luck,

Good idea.. but don't try it without a service manual. Laptops are designed to be taken apart piece by piece in specific order.. if you try it without the manual there's a very good chance you'll break something and/or get stuck with a machine you can't put back together.

These.
I am betting it is clogged up with dust.

Be VERY VERY careful with BIOS updates from HP. They are irreversible if the machine cannot start to a running windows.

I have a chill mat, it's amazing and works great.

Yeah, I don't wanna install the BIOS update... I've heard stories about it going wrong. Thanks, though. And I have a perfectly clean install. I did that the day I got it

Yeah, I never take apart a machine without a service manual. I'm a service tech on the side, and learned very early on to never touch anything without a manual.


IN REGARD TO OPENING MY LAPTOP: No can do. Many people don't know this, but newer HP laptops (as far as I have been informed) have pressure sensors inside of them. It's a safety mechanism for if the laptop is dropped and breaks open... if you open it wrong, it will trip a sensor (or sensors) and all the residual electric charge in the screen will ground out into the motherboard. At least, as far as I have been informed, that is what happens. I'm not willing to take that risk. Even if it's not true, it's scared me away from opening mine. Note to self: this is why the dv4 line was discontinued... and why it was so cheap to buy...

15 machines later, my garage is approaching maximum capacity...

Lol
I download service manuals from online. I have gigs of them

Psh, service manuals.
