ACPI and CPU/CASE Fan Issue?

Hello, well I am starting to get super frustrated about this and I am almost ready to write HP computers off for good and never buy another one.  I have a m9450f, it has a Q9300 @ 2.5Ghz, it all started with me noticing the CPU and CASE fans running FULL speed on startup and idle, after researching it I found out that it was most likely a BIOS problem and HP had to put out an update (Also Search CPU FAN FULL SPEED in google, many people with this issue with many different brands), and I have been living with it, but now I have been noticing that when my CPU load goes up to 50-70% across all cores and the temp rises to 60c the fan speeds NEVER change, I think there is a problem but HP Tech support ignores it and says it is normal.  I Have been doing MORE research and found many laptops have this issue of no fan increase due to POOR thermal/fan setting in ACPI.  I am wondering if a fresh install of Vista and Windows 7 Upgrade again will help fix this.  And before anyone asks, yes I was having problems in Vista as well but not as noticable, it was more random, now I can make my fans run full on bootup after the system has been off for a while.

Re: ACPI and CPU/CASE Fan Issue?

Snipe, how long has it been since you cleaned the inside of the case and all of the fans?  A dirty case and fans can cause these symptoms.  Also, try doing some cable management.  This will allow for better airflow to all of the components.

Re: ACPI and CPU/CASE Fan Issue?

Case is clean and dirt free.  I think I am going to live with it for now, I am getting a GTX280 and a new PSU in a few months so the new PSU will be modular for less crap in the way.  I do know it is an HP Hardware problem and they refuse to acknowlege it. Just "Sorry I can understand how frustrating it is" BS.

Re: ACPI and CPU/CASE Fan Issue?

snipe,

 

When you said that your system was "off for a while" and then the fans run full bore were you coming out of "sleep, hybrid sleep or hibernate" mode or from a dead power off state?

Re: ACPI and CPU/CASE Fan Issue?

Powered off for the night, when I pressed power to turn on the PSU fan runs full for about 2sec then the CPU and CASE fans will go 5700/2500RPMs, and it might stay like this for a few mins or it might drop to idle speeds then back up to full speed numerous times until I restart and it will be better, but I will also happen randomly during idle as I am using SpeedFan to log Fan RPMs when I am not around and when I check there is ALWAYS high recordings. It has nothing to do with CPU temp as it is usually 28c on all cores at the time it does this, also nothing is running to cause CPU load to increase fans, infact as I stated I can maintain 70% load and heat the cores to 60c and maybe higher and the fans will stay idle speeds.  HPs recomendation is set Power settings on cools to PASSIVE, ya OK I am a stupid PC user and I will let my CPU slow down its clock speed in order to COOL it.  I don't think so.  HP tech support is a JOKE, a 10yr old can do better now a days.

Re: ACPI and CPU/CASE Fan Issue?

Sound like a power on reset issue.  Could be the mobo or power supply.

Re: ACPI and CPU/CASE Fan Issue?

I dont doubt the PSU is a problem, HP UNDER powers everything.  I am getting the GTX280 abd PSU maybe sooner then I thought anyways.  I think it is POOR programing on HPs part, I think I should be able to modify my fan speeds if I want, hell I paid for it and I own it not them.

snipe,

 

You could try a second OS to verify some of your thoughts. Do you have enough space on your C drive to create a partiton for another OS?  You can use the MS boot manager to handle the OS boot selection. Or if you have two internal sata HDs you could partition HD 1 and install an OS there and still you MS boot manager. Or, disable HD 0 and install the second OS on HD 1. Then reenable HD 0 and use the ESC key at the HP blue screen to pick which HD to boot from.

 

If you are installing XP on a PC with an active VISTA system installed then let me know as there are some things to watch out for.

 

I only know one handle that goes by snipe and he plays Q.

Re: ACPI and CPU/CASE Fan Issue?

What I was going to do is install vista back on a 2nd HD and run from that just to update bios, but I am sure that is not the problem.  I have confirmed that it is not a heat issue that is causing spuratic fan speeds b/c last night I was running without the side panel and itr was idle for about an hour so it cooled down.  core 1 = 28c core 2 = 29c core 3 = 45c and core 4 = 39c.  For some odd reason 3 and 4 idle at higher temps, I hear it is normal for Quads to do that. I am currently logging my fan speeds and CPU temps with speedfan and I want to send to HP and prove to them there is a problem, it is really pissing me off that they don't have a clue about ANYTHING.  I would love to talk to an actual tech from HP so I can get this figured out but that will never happen. Every time I call they spin me around in circles and when I do the HP Chat it is the same **bleep** thing.  I took it into a computer joint but the stupid thing would not act up for them.

 

Ya I have had that gamer tag for a few yrs now, it is actually =RD= Snipe, if you ever played BFV BF2 or COD4 (short time) we had usually #1 server (Rubberducky Gaming) in the world for each of those games, but with that came ass hats hacking and pissing everyone off and it takes too much time and effort to maintain servers, and the data centers rip everyone off by putting more then 1 client on a server box causing massive lag.  Data Centers are a scam (unless you have your own gear).  Well I went way off topic, oh well its my thread.

When your processor is running low activity, idle processors can get "parked" to save on energy. You can verifty this with Task Manager (performance tab -> resource monitor -> cpu).  I see parked CPUs on my W7 system.
