Default fan controller, or one of the many daemons for the task?

Hi folks,
I have recently undervolted my laptop using the instructions in the PHC Archwiki and it is running nice and stable. I was thinking about looking at the fan speeds to further increase the efficiency of my system the system and reduce noise. I am using an Acer Aspire 5920G.
What I am looking for is more adaptive fan settings that are more in tune with the temps of the system, while keeping the fan noise to a minimum. My fans currently come in settings that seem to be 'off', 'low' and 'full', when what I really need are more adaptive speeds, i.e. more steps. Is one of the fan control daemons a better option for my needs, or is my system firmware usually the best choice. Does anyone have any comment on laptop fan scaling?
Cheers,
Scott

Hi there,
I have the acpi-cpufreq module running which I configure through the power management setting in KDE. As I'm sure you know, it works the same way as the various cpufreq modules, but can powernowd be used to control the CPU frequency using the built in KDE tool? I always used to use powernowd when I was running Gnome, but only recently made the switch over to KDE 4.4.
As for the fan speed. My laptop fan runs well enough and there is not really an issue with the fan per se because the laptop is pretty decent. My issue is really that the CPU temps seem to fluctuate. The fan seems right when under very low load (off) and when under very high load (full), it is in between where I have the issue. It seems to stay too low for too long, then jumps to full pelt when doing CPU intensive tasks, if there were more speed increments in between, this would resulting in an overall reduction in heat and noise. What I am really asking is, does the fan speed daemon provide this?
Cheers,
Scott

  • What's the idea from using one of the Tasks a common cost "Capitalization"?

    Hi,
    I want to know What is the idea behind using on of the costs included in the work breakdown structure as a common cost as a group level?!!
    and Shouldn't i include it in any transaction?!!!(i.e. don't use it in the PO, AP invoices....etc?).
    Please i need clarification,
    Thanks in advance.

    Hi
    In any project there could be some type of shared cost, that may be associated with a project as a whole, but it would not be practical to allocate such common cost to each one of the individual tasks.
    For example, a construction project will have a task for foundation, plumbing, electric wiring, etc. The project manager, and construction inspector are resources common to all those tasks, and it may be costly to try and allocate directly the hours of those resources to each one of the tasks.

  • How do I set Firefox in WinXP to print straight to my default printer rather than one of the others on my system.

    I use winXP SP3.
    I have several printer options... fax, pdf Creator etc. My default Windows printer is on my network.
    Whenever I print from Firefox the printer that comes up is the pdf Creator. I can select my default printer and it not a problem having to do so, just an annoyance.
    I would have expected Firefox to remember my last choice and offer that again, but it does not. I haven't been able to find a way of altering the choice permanently. I have no idea why the unusual choice is made.

    Many Thanks.
    Your suggestion does not actually work but it enabled me to get under the hood.
    I have toggled the altered setting back to 'true'.
    Next I right clicked '''print.print_printer''' and clicked the reset option.
    I have restarted Firefox and all seems well. My default network laser printer came up first. I used it...ok. I then changed to my pdf printer and used it...ok. I then changed back to my default printer...ok. The next print I attempted came up with my default printer... good result!
    Its fingers crossed now and I'll be careful of the resident dragons if I feel the need to mess with them again.

  • I tried to change my persona and firefox keeps defaulting to my old one before I updated my browser.Is there anyway to change this without uninstalling the whole browser? Because I'd like to keep all my bookmarks and such. Thanks

    I uninstalled all other personas besides the default and the one I want and it still goes back to the old persona unless I keep firefox on default. \The desired persona is a sports one and it keeps defaulting to a surfing one.

    Hi. The two user tips both describe a sequence of steps that should get your library from the point where it threatens to wipe data from your device to where it is syncing normally, while recovering as much information as possible. It may still be necessary to wipe and reload the device but this should only take place once all the data that can be recovered has been recovered.
    Doing step 1 of 8 and then complaining things aren't the way you want them to be yet strikes me as premature...
    Since you appear to have all your media content, and we are discussing an iPod classic, not an iOS device, the main worries are already taken care of. What's left is ratings, playcounts, playlist membership and checked status. Since your device holds only part of your library at best you could only recover the missing data for the content that is on the device using third party tools.
    Recreating the previous checked/unchecked status of every track in your library from where you are now may not be that easy. Syncing with selected playlists has many advantages, one of which would have been that you would have a named playlist that could have been retrieved by 3rd party software if you had used this method.
    You haven't explained what caused your problem in the first place, but if you have a Previous iTunes Libraries folder holding old copies of your iTunes database (generated with each iTunes update) then it would be possible to restore the most recent of these and then update the library with any changes in your media folder.
    BTW Apple doesn't offer free support for this kind of issue with iTunes.

  • Mac pro 3,1 default fan speed?

    Hey guys, ive been messing around with SMC fan Controller over the years, and have increased minimum fan speeds due to hotter ambient room temps, or simply because i was running extended cpu intensive activities. Good to take precaution since the 3,1s are known for increasing fan speed after things have already gotten too hot. This can lead to overheating. At some point within the SMC fan Controller app, i changed the "default" fan choice higher instead of creating a new blank custom fan setting before choosing my fan speeds. My problem now is that i dont know what the default settings were. i think one was 500, 600, 600, 800 RPM maybe? No idea.
    its is a 8 core 3.2 earl 2008 3,1 Mac Pro Desktop. This has different fans than all other mac pros so this question is 3,1 specific.
    I think the four fans are labeled:
    Power supply
    I/O
    CPU
    Intake
    not entirely sure because i am away from teh computer at the moment.
    Thanks

    smcFanControl's preferences are located in /Users/<user>/Library/Preferences as com.eidac.smcFanControl2.plist. I believe that if you move that to the desktop and restart, a default plist will be rebuilt for your particular Mac. If that doesn't fix it, you can always put the plist back where it was.
    Or, you can simply make smcFanControl not a startup item and then use something like iStatPro to see what the unadjusted fan speeds are because smcFanControl doesn't change the built-in speed defaults, it just overrides them as the lowest fan speeds.

  • Need tech help for MSI VGA Fan controller for gtx 780 SLI

    Just curios how to get the VGA Fan controller to work on the 2nd card that's in SLI? I can get the 2 fans to run 100% with afterburner but the middle one wont on the 2nd card? Thanks!

    I have the same problem. 
    On GTX 780 Lightning, Afterburner will control both cards 90mm fans.  Afterburner will not control the middle fan (fan 2).
    The MSI fan controller will only control one card, not both.  I think there was a major oversight here.  They either weren't thinking anyone would SLi GTX 780 Lightning when they made the fan controller or its horribly broken.  In my case Rakunvar, my bottom card (PCI-E slot 5) is controlled while the top card (PCI-E slot 2) is ignored.
    I heard somewhere, they plan to fix Afterburner so it will correctly work with the 780 lightning.  It seems to me they put the MSI fan controller in the box with the GTX 780 Lightning because they must've known that the current beta Afterburner wouldn't control the middle fan. 

  • Return the scheduled start date from one task to a custom field for all tasks

    Hi all
    I am trying populate an entire custom task date field with the scheduled start date of one of the tasks. I thought the easiest way would be to:
    1) identify the date I need with a custom task flag field set to 'yes'
    2) create a formula to look for the 'yes' flag in that field and populate the custom task date field with it.
    This worked only for the task where the flag was set to yes (task #36) and the rest of the 49 tasks returned an error message. I'm unsure of how to set this up so that the date with the 'yes' flag populates in this column on
    all 50 tasks.
    This would also need to scale for situations where there were more or less than 50 tasks.
    Thanks in advance...

    ShelleyBrodie,
    That's because the syntax of your formula isn't quite what you intend. The correct syntax is:
    IIf( expression, truepart, falsepart )
    For your case that converts to:
    IIf([Flag1],[Scheduled Start],{not sure what you want for the false part but I assume is is not Scheduled Start})
    Note, the "Yes" for Flag1 is implied, so the first part (i.e. Scheduled Start) is the truepart, but you don't give a value for the falsepart (i.e in both cases your formula is looking for Flag1 to be "yes". Let's say you want the Date1
    field to have the Scheduled Start date if Flag1 is "yes" and to have today's date if Flag1 is "no". Then the formula will be:
    IIf([Flag1],[Scheduled Start],[Current Date])
    However, As I indicated in my previous response, you won't be able to do what you described in your initial post by using a formula. Are you now trying to do something different?

    Hello together,
    around 4 weeks ago i have bought a new T410 laptop. Everything works fine, but i have so problems with the battery symbol (big one) within the task bar. Within the lenove power manager the option to display the symbol is selected. Sometimes it is visible, sometimes not.

  • Workflow title is showing the task name

    Dear all,
    I am new to workflow and would like to ask your help about this issue I am experiencing.
    My workflow is a copy of MMIV_Appr. One of the tasks is TS99900067. The title is defined as "Invoice Release & &" where the first ampersand represents the document number and the second is the fiscal year. However, when the workflow approver receives the email in his SAP inbox, the title becomes "Invoice Parking: Approve Release", which is the name of the task. How can I make it display as the correct title "Invoice Release & &"?
    This issue is happening after we introduced some changes in the PPOME org structure.  I have refreshed the workflow buffers via SWU_OBUF and PPWFBUF.  I will to have the user refresh the org structure from the SAP inbox.  SBWP ->  Settings -> Workflow Settings -> Refresh Organizational Structure.  I am not sure yet if the steps would help resolve the error.
    If you have some inputs, I would greatly appreciate them.  Thank you for your help.
    Hoops

    Thanks to everyone who responded to my query.  I awarded you with points for helping me.
    It seems the workflow item text encountered a few hiccups after the PPOME org structure was changed.  After refreshing the workflow buffers and the org structure from the SBWP inbox of the user herself, the workflow item text went back to normal.  The effect is not retroactive, though.  So, for items impacted by the PPOME change, they remain as-is but for subsequent items after the refresh, they now reflect the correct text "Invoice Release (document number) (fiscal year)".
    Steps done:
    1. Refresh workflow buffers via SWU_OBUF and PPWFBUF.
    2. Refresh the org structure from the SAP inbox.  SBWP -> Settings -> Workflow Settings -> Refresh Organizational Structure.
    Thanks guys!

  • I have 3 older ext. hard drives that I've utilized many times. Today while searching for old files, one of the three is no longer recognized by my PowerMac.  Any suggestions?

    I have 3 older ext. hard drives that I've utilized many times. Today while searching for old files, one of the three is no longer recognized by my PowerMac. The drive is not listed in Disk Utility.  Any suggestions?

    Is the computer in you equipment line:
    Dual Core Intel Xenon
    (which is not a PowerMac but a Mac Pro) the one you are asking about, or do you have an older PowerMac?
    If a Mac Pro, their forums are here:
    Mac Pro
    and, as Mac Pros have a totally different architecture from the pre-2005 Macs this forum covers, you may not have the same issues that can affect the older models. If someone didn't notice your equipment line, you could get advice that doesn't apply.
    If you really have a pre-2005 PowerMac, read on.
    If the stubborn external is USB and does not have its own power brick (i.e., it gets power only from the computer's UBS ports--"bus powered"), it may not be getting enough power. As electric motors age, they can demand more power than when new, and the power available on any USB port is limited.
    The typical workabouts to making a computer recognize an aging, bus-powered USB drive are:
    Get a powered USB hub (has its own power brick
    Get a "Y" USB cable: 1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
    The second gets power from two USB ports on the computer and often that's enough.
    Remember that the USB ports on your keyboard seldom provide enough power even for a thumb drive, so be sure to use the USB ports on the back of the computer.

  • How does one change the dictionary default from Portuguese to English?

    In one of the upgrades, instead of defaulting to English, my spellchecker instead defaults to Portuguese, which is the first language listed (also have French and Spanish). So every time I open Firefox, I have to change back to English.

    I've had this problem for over a year. I have three dictionaries installed, but when opening a text box i.e. on a web page where text may be entered e.g. to create email or fill a form on line, 90+% of the words are red-wavy underlined because the dictionary in use is not my native language, but one I may occasionally try to use when I must...which is rarely.
    Firefox NEEDS to have a setting for the Default Spell-Check Language, and it doesn't have one.
    Unfortunately, I stopped coding some thirty years ago, and would love to do the fix, but I've simply been ignorant too long and must beg this of the fine developer crew out there.
