KT4V and Enermax fan at SFAN connector

I have a KT4V MoBo with a temperature running a bit high so I decided to add a fan at the SFAN connector. I connected an Enermax fan, UC-8FAB-B (with manual adjustable speed), to the SFAN connector. The system run for some seconds, then stopped. When I tried to reboot, it all stopped at 3 red LED and one green LED on at the D-Bracket with 3 beeps. This indicates a memory error. Unable to get the system to boot.
I tried with the fan directly to the PSU and the fan itself worked ok. (Even at the SFAN connector eventually) but the system do not reboot at all.
I have measured all voltages at the ATX power connector and they are ok. I have tested the RAM in a different system and it is ok. Do the fan have a current rating to high, destroying something such as the voltage supply to the RAM ?

Regarding the high temperature on the CPU (max 64 degrees C) I tried to remount the CPU fan with Arctic Silver Thermal Compound with the same result.
Regarding the SFAN header: the current of the fan might have blown something on the motherboard. I should like to have the specification of the system SFAN output as to max current rating, as to avoid destroying something in the future (should be in the user manual).
I should also like to know how and wher the voltage to the DDR RAM (2.5 V) is generated. (Could be a fault here).
I have returned the KT4V to the seller waiting for an answer to RMA..... ?(

  • MSI KT4AV and PSU FAN connector?

    MSI KT4AV has 2 fan connectors: CPU FAN and System FAN. What about PSU FAN - is there PSU fan connector on this mobo? Can I connect PSU Fan to System Fan connector?

    I've read that PSU Fan is not powered from Fan Connector, but it's only uses it to measure RPM of PSU Fan. RPM of PSU fans is controlled by PSU (Chieftec 360W HPC-360-202 DF). Is amperage so important in this situation? Sorry, if it's lame question but I don't know too much about PSU's. ;-)

  • My Macbook air no longer shows battery and the light on the connector is not on can someone help me please?

    My Macbook air no longer shows battery and the light on the connector is not on can someone help me please

    i saw that someone had updated to maverick and had the same battery issue and fan issue so I reset the SMC and everything is ok now

  • PS and CPU fan comes on merely by plugging in AC power

    I am repairing a friends Athlon xp machine and have tested everything with extras.
    I put a new MSI KM4M-V board in.  The pc runs xp fine, etc., etc., however, when shut down the pc, Windows shuts down, but the ps and cpu fan stays on.  Indefinitely.  I have to either flip the on/off switch on the back of the ps or pull the damn plug.
    What gives?
    When I plug the thing in cold, same thing; the fans come on and then I press the start button whenever I want and the system posts and boots normally.
    A motherboard Short?  I checked the switch and even pulled the connector; the fans still come on when I plug it in.
    Any thoughts?
    Thanks.

    Yes, I've let it run for hours after Windows shuts off, it simply doesn't go off.
    Simply plugging it in or flipping ps switch, the same thing; ps and cpu fans come on automatically.
    I've read all the APIC threads; if I were strictly having problems shutting down, maybe it be that.  But it is so strange that it does it from a cold start.
    Got to be some kind of short, or else a bad board.

  • Can 945P Platinum control on-board sysfan, nbfan and pwrfan fan speed?

    I bought a couple of 8" case fans. These fans comes with a connector (with 3 wires) which i connect to the motherboard fan connectos (pwrfan, sysfan, nbfan). Using "SpeedFan" software, i can see the RPM of these fans and even my CPU fan. But it seems that i can only control the speed of the CPU fan, but not the other fans. I reduce the fans speed to "0" on SpeedFan but the RPM does not seems to be affected.
    Can the RPMS of the fans be adjusted fron SpeedFan? ???

    I too am having problems with Speedfan.  My PL945 Neo5-F reports, in speedfan, the existence of 4 fans.
    Looking in the manual to identify what's what, it states that it supports 3 fans - CPU, Sysfan2 and pwrfan2 - what happened to sysfan1 and pwrfan1?
    Anyway, I managed to work out that although speedfan reports 4 fans, it seems only able to control cpufan1 (fan1) and sysfan2 (fan 2).  Neither fans 3 and 4 map to pwrfan2 (what is being reported).
    If anyone has cracked this nut, please let me know.
    I suspect it is something to do with the address the other fans report to - but I don't know how to find and fix it.
    Core Center simply crashes and won't let me do anything.  In fact, I can't get the front end to even appear now, no matter how many times I uninstall and install it.
    I'm running Vista HP with 2 gb and a core 2 duo 6550.  Graphics is a Saphire Radeon 3600).
     

  • MBP Freezes (have erased and installed, ran disk utility, and inc fan speed

    Hi Guys, Any advice on this issue would be very much appreciated please.
    Have had an original mbp for about 2 and a half years. Last few weeks it's been freezing between 1 and 5 times a day. By freezing I mean that the screen freezes and there's no cursor or keyboard fuctionality. Sound stops too. This happens using World of Warcraft, Pages, Office for Mac, and Safari, sometimes also the finder. Main culprit though is Safari and WoW. For comedy value, I'm a priest in WoW and it froze during a raid which resulted in the whole group wiping out! Great timing! lol
    So far I have:
    Ran disk utility, repaired permissions and verified disk.
    Did a complete erase and install.
    Downloaded Fan Control and set to 3400 base speed, left fan @ 3503 RPM and Right fan @ 3508 RPM - temp reads 46.9 oC (118 oF)
    I'm guessing that since my erase and install, that it is very much a hardware issue as the problem has happened again.
    Since I've done the fan thing, nothing has frozen so far but I only did it about an hour ago.
    If anyone could offer any other suggestions in case it does freeze again I'd be very grateful indeed :0)
    Oh - one thing I don't get is that only about 4 hours after my erase and install I did the disk utility once more (Repair permissions and verify) and it came up with the below list - which is huge given it was a fresh install. Not sure if the below info will help (not really sure what it's for tbh - but there it is.
    Many thanks,
    Vizzy

    According to Mactracker, your Mac could recognize 3 GB of RAM:
    http://www.mactracker.ca/
    One thing to check is your RAM usage while playing WOW. I am not a gamer, so I don't know if you can play with your Dock visible, but if you can, here is an easy way to keep track of your RAM usage.
    Go to Activity Monitor (in your Utilities folder in your Applications folder) and put it in the Dock. Then while in Activity Monitor, go to View (in the menu bar)>Dock Icon and select "Show Memory Usage".
    You want to see a lot of green in the pie chart. If you don't, you are running out of RAM and then the computer turns to your hard drive to fulfill the functions of RAM. This process is much slower, and I could see it resulting in freezes. If you find that the green virtually disappears while gaming, you could well benefit from upping the RAM by another 1 GB to 3 GB total.
    Good luck!

  • Mini Mac, no light, and roaring fan!

    Hi chaps please could you advise on my mini mac prob,
    Basically unit was completely switched off for a couple of days, when switched on it booted up to a white screen with the apple logo and spinning timer which kept locking up.
    I did a PMU which got me functioning properly (seems to be) but has left me with no indicator light and the fan keeps roaring away at an exaggerated speed.
    thx for your time( I have rebooted/restated/shutdown several times but no different

  • MacBook Air is laggy and the fan is out of control

    My MacBook Air 2013 is laggy and the fan is out of control. The fan is out of control even when I start my macbook up. I don't know if it has something to do with Yosemite or something else. I have tried SMC restarting, and nothing has changed. I would really love to hear if anyone else is having this problem, and I would love to hear if any of you have any tips. Also I checked if anything is using up my CPU a bunch, and nothing is out of the ordinary.

    The kernel is using excessive processor cycles. Below are some possible causes for the condition.
    Throttling
    When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
    ☞ a buildup of dust on the logic board
    ☞ high ambient temperature
    ☞ a worn-out or faulty battery in a portable
    ☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
    Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
    If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
    Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
    Installed software
    User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
    Corrupt NVRAM or SMC data
    Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
    External display
    Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

  • Macbook pro dock - with ext hd and ext dvd burner and cooling fans needed??

    why doesn't anybody make these? I could have a 1 terabyte HD, dvd burner and cooling fans to keep the macbook pro cool enough to touch while playing wow, or editing video. It could also be made of aluminum and look great. Oh and it has to be configurable to allow use of any 15" macbook pro(ie, bookends units are different because new models include firewire 800)

    Welcome to Apple Discussions!
    Do you have iStatPro? You can download it from the Apple site and see what it is that is running so hot. Under the low usage you describe, the fans should be idling silently. And you might be able to tell what is getting so hot.
    If Activity Monitor doesn't show anything, then you might want to run the extended version of the Apple Hardware Test. It sounds like something is getting very hot. If there is a hardware problem, then you should get one or more error codes. The Apple Hardware Test is on Install Disc #1 of the gray discs that came with your Mac--you boot to it by holding down "D". Instructions are on the disc and on the screen.
    Also, be sure you have "All Processes" selected on the Activity Monitor. And the boxes at the bottom should be mostly black with very little red or green at 3.5% CPU usage. Given all the symptoms, I am surprised that there is not some process running amok in the background.
    Good luck!

  • Hot Hot Hot. My Powerbook is hot and the fan never turns on!

    Hi,
    I downloaded the istat pro widget in order to monitor the heat and fan on my Mac. Currently the CPU top is 141 F and the CPU bottom is 140 F. The front and rear fan are not on and it seems like they should be.
    When are the fans set to turn on... can I change this?
    Are my fans not working.
    Give me your insight. Thanks!

    Look here:
    Apple Specifications
    http://support.apple.com/specs/powerbook/PowerBookG4_15-inch_1_67-15GHz.html
    Electrical and environmental requirements
    Meets ENERGY STAR requirements
    Line voltage: 100V to 240V AC
    Frequency: 50 to 60Hz
    Operating temperature: 50° to 95° F (10° to 35° C)
    Storage temperature: -13° to 113° F (-25° to 45° C)
    My computer temperatures are constantly on the upper end of the scale, as well as frequently going over the operating specs listed by apple. I believe these are environmental conditions for operation, but currently my cpu temps are 120/114 according to istat, so this should give us some ammo for repairs, a recall, or something, as the obvious internal temperature is not within Apple's operational specs. Even my powersupply is 109f currently...
    This has got to be wrong... Lets fix it apple!

  • Can an error in battery cause a slow CPUS and the fan to run non-stop?

    tthe battery need serviced but my computer runs slow and the fan is running non-stop. MacBook Pro 13" purchased around 2011.

    OK, you really need to dump that Windows attitude quickly, because what worked over there is completely useless here.  I never understood the "upgrade didn't work obviously, because this or that happened, so how do I downgrade."  I hang out around here, and I haven't seen many comments about fans running full blast after the updates. I did them, and nothing happened.
    First, you can't downgrade the firmware EFI update.  I think if you tried, it would brick your MBP.
    You could reinstall Lion if you wanted, but that's really a pain, and once again, one of those Windows things that people always do that wastes time.  A security update and Remote Desktop Client (which only runs if you start it up) would not effect your fan speed.
    Apple does have "restore points", but it's a real backup system that requires a backup drive.  It's called Time Machine and it's preinstalled on your Mac, easy to use, and allows you to go as far back in time on your Mac as the size of your backup drive will allow.
    Now, after all that, let's try to figure out what's going on with your fans.  First, did you do the EFI update correctly?  Meaning did you do it when the MBP was actually plugged into the wall?  What are you running?  Games?  Videos?  Something else?

  • Connectivity between SQL Serevr 2008 and SAP BW using Microsoft Connector 1.0

    Hi ALL
             I am trying to connect to SSIS 2008 to SAP BW using Microsoft Connector 1.0.
    Following are stepes I performed.
    1. Created RFC on SAP BW Server.
    2. Created Prcess Chain in SAP BW.
    3. Created SSIS Package using SAP BI Source. Here I set Execution Mode : P Trigger   Process Chain.
    The process chain is executing fine on SAP BW Server, But it is unable to send back a
    notification to SSIS package.  And here my SSIS package failed.
    I am getting following error message :
    [SAP BI Source] Information: Process Start Process, variant Start Variant for MSBI has status Completed (instance D8Z84GJ2RLV7WCI2IYK5CZ1R3)
    [SAP BI Source] Error: An internal exception occurred.
    Microsoft.SqlServer.Dts.SapBw.Connectivity.ERPException: 
    An error occurred during the dispatch of the incoming function. The last return code was "RFC_FAILURE".
    Before this error I am getting following messages are :
    [SAP BI Source] Information: Process Data Transfer Process, variant Z09_O101 -> Z09_H101 has status Active (instance DTPR_D8Z84GJ2RLVZKYTTUHZRFEG0V)
    [SAP BI Source] Information: The component is waiting for a notification.
     Is there any way to test the both the way connections?  I mean SAP BW -- SSIS &                SSIS ---  SAPBW.  
    Can any one please explain me entire connectivity architecture between SSIS and SAP BW using Microsoft Connector 1.0. (I mean how these RFC are working and how SSIS is pulling the data from SAP BW)

    I am having the same problem. We actually loaded data a few times but now it does not work. It is amazing that we cannot find help for this problem. Has anyone been successful using the BI connector 1.1 to load data to a BI system using SSIS. I think
    this had to do with either a DLL problem on the machine running SSIS or the Service Pack level of the BI system. I cannot find any documentation showing versions. I have looked through the documentation that was written back in 2008 but can't seem to
    get it to work.
    Sorry we are trying to push data (BW Destination) to BI it looks like you are trying to get data from BI.

  • My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.

  • KT4V and KT4A-V differences....

    Hello, I had a kt4v and just finished setting up harddrive the way I wanted it, then had problems and had to get another. Well, I got a kt4a-v instead,thought they were exactly same but one of the chipsets are different(VT 8237 on KT4A-V and VT 8235 on KT4V). I was wondering if I'll have to format and reinstall or can I use the harddrive with the KT4V info on it? Thanks

    Thanks, you were right, drivers cover both vt 8235 and vt 8237 chipsets.
