Hi Ive just puchased a new pc, not sure if this is o.k. but the CPU fan runs constantly at 2700rpms it never stops and never drops below the rpms. CPU usage runs at steady 4-11%, its a new pc and ive hardly installed anything on it. Only asking this because my old PB's CPU fan used to run when i worked my pc hard and stop when system was idling. I've had a look in bios and theres no Q-fan option, i noticed Smart fan was Disabled so i enabled that and now its bought the CPU fan speed down to a steady 1700rpm but still runs constantly at that speed. I use PC Wizard 2008 to monitor my pc here are the specs, Hardware Monitoring : ITE IT8718F Voltage CPU: 1.22 V +3.3V Voltage : 1.52 V +5V Voltage : 5.07 V +12V Voltage : 8.49 V DIMM : 1.20 V VTT : 1.52 V VBAT : 3.22 V Processor Fan : 1713 rpm Chassis Fan : 2547 rpm Power/Aux Fan : 10 rpm Processor Temperature : 17 °C Processor Temperature (Core 1) : 38 °C Processor Temperature (Core 2) : 31 °C Mainboard Temperature : 24 °C Power/Aux Temperature : 23 °C ACPI Thermal Zone : 40 °C : Video Monitoring : nVidia Driver GPU Temperature : 62 °C GPU Diode : 62.6 °C GPU Fan : 100% : Hard Disk Monitoring : S.M.A.R.T Hard Disk Temperature Hitachi HDT725025VLA380 : 32 °C And here are my PC specs CPU Intel® Core™ 2 Duo E4500 (2.2GHz) Motherboard Foxconn 45CM/GM Memory 1GB DDR2 PC2-4200 (2 x 512MB) Hard Drive 250GB SATA hard drive CD / DVD Drive Dual layer DVD±RW Card Reader Flash Memory Card Drive (8 in 1) Video / Graphics Card GeForce 7200GS PCI-E 128MB dedicated(up to 512MB hypermemory) Sound Card Realtek ALC High Definition Audio Network Card Realtek 8139 / 810X (Onboard) Any advise would be great. Another thing i have noticed is my Processor frequency is 2200 Mhz but at current it states 1197 Mhz is that o.k. Please note i am no PC expert so be gentle. Thanks Steve
Your +3.3 and +12 volt are really low, but that could be a software qlitch. Not for sure if it would even boot with 8.49 on the +12V. If your CPU runs steady at 4 to 11% theres got to be something running in the back ground. Have you checked under processes to see whats eating your CPU time?
Cheers IamOne Ive looked and theres 51 processes and my cp usage is hovering around 3-8%in the CPU colomn its highest ones are system idle 95 taskmgr.exe 5 dwm.exe 5 system 0 -1 in the memory column the highest ones are svchost.exe 43000k mcshield 30000k iexplorer.exe 29000k dwm.exe 25000k msiexec.exe 11000k the above memory reading are a rough guide and the do fluctulate constantly around those reading. Thanks, Steve
Oh Vista, well Vista eats up more. the dwm.exe is the Aero/Live window previews. CPU temps. are alittle on the warm side, but I beat your running a stock cooler. If your CPU is running around the mid 30c idle the 1700rpm for a stock cooler is not to uncommon
Steveveg, It should be your PSU. Please check it on another PC (if you have any free). What's your PSU? Oh and you shouldn't be worried about your FAN. Download Speed Fan program and take a look if you can control CPU Fan's RPM. If not, go then to your BIOS adjust it. I suggest leaving ~1800 rpm and monitoring temperatoru of your cPU. Thats it for now.. waiting for reply
Newer processors and bound to produce more heat (and require more cooling) so that sounds fine to me. where does it tell you that your CPU is running at 1197 Mhz? and does it by any chance refer to it as "current CPU speed"
Thanks for that yes 1197 MHz is my current frequency it tells me that information in PC Wizard here is the info, does everything look o.k. Thanks, Steve
have you updated your bios recently? Some Bios updates make the fan run consistently but at lower speeds to keep the whole computer cooler, Again Where in some instances, the fan only kicks in when the pc gets to certain tempertures. Again you could also try updating your bios to the latest version and see if that corrects it.
Don't advice him to update his BIOS cos, the computer copanies are just waiting for a reason to cut his warrancy. But you are right about that there are BIOSes, that make the fan run cotinuesly for the reason you mentioned . Those values for the 12V and 3V are not real. If the 12V is 8.5V your PC will never boot. There is a signal that goes to the BIOS when starting. It's name is "Power good signal". If the BIOS don't like the values from it the whole system won't boot and you'll have just a black screen. About the CPU. Intel Dore 2 Duo run at CLock: 200Mhz Multiplier normal x11 which makes 2200Mhz BUT New processors lower their multiplier so that they can consume less electrisity. So your multiplier varies from 6 to 11. It is 6 when your CPW usage is bellow 20%. So 200x6 is 1200. And this is completely normal. Try to put some heat in it with some CPU usage process to see it work on 2200Mhz.
