Hardware :: Bad To Plug Case Fans Into Motherboard?
Jul 8, 2010
I am going to upgrading the cooling in my computer, so I bought 3 case fans (the amount my case has room for). They have 4 pin connectors, so I was just going to plug 2 of them into the 2 available fan headers, and then plug the last one into a molex connector considering that they all come with molex adaptors. However, according to this site, your not supposed to because its too much strain on the motherboard? I am not (never have never will) overclocking so is that just for overclockers? My motherboard manual says it will work with 12 volt fans which are what these are.
I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.
Quote:
-iso-level level ......................... With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_). ...........................
However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.
Code:
root@darkstar:~# mkisofs -iso-level 1 -o image John Smith.txt Total translation table size: 0 Total rockridge attributes bytes: 0 Total directory bytes: 0
I tried to add my wife , and when I put in a password for her, this error comes up."Please set a valid user name consisting of a lower case letter followed by lower case letters and numbers." I did all that and I still can't set a password for her.
my computer sounds as if I have been playing crysis warhead for like 5 hours, because every fan in my computer is running including the graphics card. They are not just running normal either they are running at the max.
I have problem with funs speed in my fujitsu rx100 s6 server, rpm funs is 3000 ? I think it is not standard speed funs. On windows 2008 server funs works quietly. Fujitsu supports only windows servers, red-hat enterp. and suse enterp. Is there any software to control speed fans?
I am trying to use GKrellM [URL].. to monitor my system's fans/temperatures (I am trying to undervolt the fans a bit to make the systems quieter), but there don't seem to be any sensors available. I have lm_sensors installed.
I'm finally making the change away from rhythmbox for the now adopted Banshee and I'm noticing that my fans run really hard when I'm running banshee. I'm monitoring speeds and don't notice a huge increase in temp but the fans none the less run hard. CPU usage is running around 6% for banshee not nearly enough to cause this fairly large laptop so having the fans run hard make it a bit loud when around others
I just did a clean reinstall of Ubuntu (10.04 --> 10.10). After the install, any time I do CPU intensive work, my PC is suddenly shutting down like it's overheating.Everything was working fine for months, and started having problems immediately after the reinstall. so this is not a problem with my hardware, and it's not a problem with my fans needing cleaning -- it's a problem with software. So please don't tell me "that sounds like overheating, clean your fans". Something is different in software-land between 10.04 and 10.10 that is causing this to happen -- I assure you that the upgrade did not magically fill my fans with cat hair.
I have checked my log files, and can't find anything related to overheating -- searches for things related to lm_sensors, "temp", and "thermal" are not turning up anything in the system logs (syslog, kern.log, or messages). I also looked at the logs around the times of the sudden shutdown, and couldn't find anything unusual.How can I diagnose this? I'd like to file a bug report, but since I can't find anything in the logs, I honestly have no idea how to go about providing useful information.Is there anything besides overheating that might be causing my laptop to suddenly shut off?
I upgraded my Asus Eeepc 900a to 10.4 yesterday. Since then, Xorg has averaged between 30-40% CPU, and my fans have gone nuts running high/low/high/low, ad nausium.
Any ideas what might be going on? Another clue perhaps: on reboot or shutdown, I get a "program not responding" message with "unknown" as the hung program. I have not been able to determine what this program is or if it is related to the hyperactive Xorg.
I have an HP ProLiant DL560 server with Debian 6.0 installed and cannot figure out how to get the fans to run at anything except high. I have searched google and this site, but cannot find anything that works on Debian 6; the SLES packages will install, but don't do anything.

I have noticed a really bad problem on here that i never had on windows 7 even with overclocking.
It seems the fans stay on and are basically idling or are at minimum speed and the computer and graphics cores are just idling at 99c which is really dangerous, but not critical yet since this is an alienware laptop and the technician did say its temperature rating is above that.
The problem is I need to get the multiple fans in the case to start up and cranking like they do to keep the system really cool in windows 7. I kinda wanna get this fixed ASAP as i dont want to constantly be running at this temperature.
I do have one question about the latest Ubuntu server edition 9.10. Currently I am using 8.04 on a server at home and have nothing but great things to say about it.
With that being said, what would be the use case for an average joe like me to harness the new capabilities in 9.10, more specifically in regards to the new EC2 features?
I am a web designer and video geek...I was wondering if this would take some of the workload off my Macs. For example video rendering, etc. Should I uprgrade and try this out?
This is probably a simple question but I really don't know!How do you measure a case fan to know it's true deminsions whe one is talking about them or whatever?For an example lets use an 80 mm fan, is it measured from the "Frame" size witch is the total size of the fan or what?
As you know that GNU-C provides qsort() function in <cstdlib> in this prototype
Code:
You may know about Selection Sort Algorithm already, I want to write a function to perform Selection Sort but it can apply generally for many type: int, long, float, double... like qsort() above.
The sort utility in Ubuntu 10.04 (Lucid) always sort by case-insensitive, just like if you specify --ignore-case to it. The two sort just give the same result:
[Code]....
But sometimes I want to sort by case-sensitive, so the upper-case letters come first, then lower-case letter.
I have a My book usb drive that in the provious install would show up with a My book icon as a "drive" on my desk top, in PLaces it shows as a blank icon.. for some reason the icon does not appear on my desktop, like normal, examples plug in ipod, ipod icon shows up, usb mini drive, that shows up?Also this could be related .. but my Pidgen icon on the tack bar does not show anymore... it used to be that I opened it and a little green icon sat by the clock?
I recently upgraded my HDD to 160 GB ..I actually wanted to exchange the old HDD (40GB) and adjust with the price of the new one..The comp service guy said that the internal HDD could be used as a USB disk if I purchase a CASE for this..I bought a case thro which I attached the old IDE HDD... The LED is on when I connect (The USB cable had 2 leads which I had to connect it in 2 USB slots- Direct in my cabinet (not thru Hub),,, Ubuntu 10.04 is recognizing the disk in "System Info" as "USB - Generic HDD"...But that's it, I am not able to run Gparted or anything...Even in win7 , it said "Installing software for devices" and later on nothing happens...This is not shown in File Manager I would like to know how to format and make it usable..
Also , since HDDs involve some amount of power , is it wise to connect it to another computer, I mean there wont be an overload or spike or something like that?? We have 220 Volt electricity in my country... Aso logically speaking there has to be a limit I mean, you cant keep "chain loading" multiple HDD through USB Hubs ,right!!
i am trying to set up a couple of pages in some special directories URL...but i need it that if they type URL... for them also to go to the site and not to a 404
I've observed that if I copy a directory containing some files to an USB stick, files whose names are all upper-case are copied with all lowercase names. Is this expected behavior? The USB stick is shared with a Windows box.
how to configure openSuSE 11.1 to automatically power off when I push the power button on the case? I have no monitor, so I need the system to power off normally when I push that button.
how I can use the mv command to move a file that matches *.ext regardless of the case?
I would like to be able to move:
*.ext *.EXT *.ExT
....and so on with a single command. I do not want to have to type out all combinations of this single file extension in my script because my file system is case sensitive.
