Plug in Bat.case fan "cooling"

Apple news about new products has overloaded several ISP. " LOL "
Has any one developed a fan that can fit into the Battery hole on the PowerBook, as I run it mostly on AC and have the battery out and stored for travel only and so use Cat6 networking.
I was wondering if when the Airport card is out if there is enough space for air to flow via the Airport opening into the rest of the PowerBook.

Hi j
1. I don't think such a fan ought to be necessary.
2. For best performance of your battery, you ought to be using it from time to time. You should at least put it in, run it down and charge it back up every now and then. If you don't battery life will suffer.
Peace

  • Case Fan Question

    Alright guys, here's the problem. I just got my Radeon 9800Pro and all though it's sweet, it's pumping out too much heat. The heat is upping my case temp and my CPU temp which is fine for now when my P4 is @ stock but when I push it to 3.2GHz it's not. (The 3.2 barely upped a deg. when i was gaming w/ my fx5600 btw) So i'm doing two things to correct the problem. Buying a CPU fan (Zalman 7000-AlCu) and buying a VGA fan (Arctic-cooler VGA Silencer). I've heard these are good products. Anybody disagree? But that's not really the problem. Prob is my MSI board only has one case fan power adapter and I have another case fan I'd like to install it. Is there any way I can jerry-rig the 2nd case to somehow run as I'm sure it would aid a little bit in disappating the heat from the Radeon card? Thank you for your help and sorry for the long post. Ciao!

    Two hard disks? You mean if I wanted to add two more hard drives excluding the ones in my system? Well thats great then. I'm just concerned about putting in a fan controller and some fans and shorting out my PSU. Thanks a lot guys. Ciao!
    edit: While i'm on the topic, does anybody have a good fan controller they recommend or what I should atleast be looking for? Oh, and when I get my fan controller, there's no way my rear exhuast case fan will reach the front of my system to plug into the controller. How can I extend the wiring? Thanks!

  • [865PE/G Neo2 Series] Suggestions for excellent Air/Fan Cooling - P4 Northwood

    Guys, I need some advice here.  I've got my 2.8 Northwood up to 3.16 (yea, I know, not great or anything but good enough for right now). 
    Anyway, with the coming of the blazing Summer temps hitting Michigan in the high 80-90s, my case and CPU temps are skyrocketing.  I am finding that my idle temps, once at 31C are now at 35-36C, and the CPU temps once at 42C max under load are now reaching 50+ C.  Also, this is the first time in months upon seemingly endless months that I am now getting random reboots, and I am sure it is due to soaring temps and heat problems.  The room temps here are killer, and right now are in the high 70s...    
    I would like to please hear your suggestions/recommendations on a good AIR/FAN cooling solution for my specs I have listed below.  I am looking for something that is not very loud if possible, I welcome and thank you for your comments!

    I only know that I can't suggest a HS and fan because my temperature is higher than my 2.6GHz Northwood's since i decided to install the Thermalright XP90 and the 92mm UFO Thermaltake fan(~82CFM max.). I recently discovered an old picture from Speedfan saying CPU temp: 40C!!! Now right after boot up, I get 40-44C idle and it can climb up to 60C at full load. I know for a fact that air flow is bad inside the case but it's unbelievable to have 40C+ idle. It can't possibly be the air flow so soon after boot. The pressure (and contact) on the CPU was enough to actually see my CPU stuck on the base of the HS after removing the HS!!! A few pins had to be straightened too.
        So, from my experience I think you already rock, since we have 30C(86F) already where I live. The feeling of the XP90 crashed under my boot will ease my pain...Oh, yes it will.
    P.S. I 'll give the Arctic Silver a try before smashing the XP90 junk...

  • How do I fix my case fans??

    I have two 80 mm case fans (12v). I was wondering what the allignment of the fans should be. Should These fans blow air INTO the case or should they SUCK OUT the air from the case. I currently use a 350 Watt CODEGEN PSU with a single fan which sucks air INTO the PSU and hence INTO the case. Problem with sucking air into the case is that a lot of dust gets into the cabinet. On the other hand, sucking air out of the case leaves lesser air for the CPU and NB fans to effictively cool the CPU and NB. Any sugestions??
    I plan to overclock, but not right now. The temperatures at no load are as follows:
    With Side Pannels Fixed -  CPU=51 Degrees Cel   System=44 Degrees Cel
    Without Side Pannels (Open Case) -  CPU=43 Degrees Cel   System=41 Degrees Cel
    Is my comp overheating?

    As mentioned in the other of your thread, you PSU is weak currently, so maybe when you get another PSU, it should be intaking air to the PSU and exhuast out from the rear.
    Just always remember the rule of "Hot air rises and cool air falls" and you'll most probably know where the fans are to be placed. Next, you should always try to keep the same number of intake fans and exhaust fans to keep a good capacity of airflow within the chassis.

  • Mac Pro Tower - Which Fans Cool All of What?

    So I have a 2008, 2.8 GHz 8-core Mac Pro tower.  I'm one of the many people who have problems with the fans.  In my case, I can get really high fan speeds, and the problem seems to be due to a faulty temperature sensor.  (Using iStat, it will sometimes show unreasonably high temps on a couple cores [or the heat sinks, apparently] immediately after turning it on, whether or not it's been off for awhile.  Sometimes, it will even show negative temperatures, in which case the fans will really go into overdrive.  Yes, I've already tried resetting the SMC and cleaning it out - nothing.)
    What I've ended up doing so far is download Macs Fan Control and setting it to base the fan speeds off CPU temps that don't give faulty readings.  This works really well for lowering the fan speed (and thus noise), but I understand that different fans cool parts of the system besides just the CPU.  The fan names give basic descriptions, but not a lot of detail beyond that.  I've been trying to find a diagram showing which fans cool which parts of the system, but I mostly get results about fan noise, or minimalist diagrams that don't tell me all I want to know.  I'd like to make sure my settings are fairly optimal before I do anything intensive.
    Can anyone help me with this?

    I think you are "barking up the wrong tree".
    The fans in the Mac Pro are controlled by Software in the System Management Controller. They make a feedback loop based on measured temperatures. If you are getting racing fans, that is probably based on Bad Temperature inputs. Fixing the temperature inputs is where you should place your energy. The fans are slaves in this process.
    One possible exception: Most of the fans do have an RPM output indicator, which tells whether they are spinning properly. If the diagnostic indicates a MOT error, that is likely to be a Fan Motor that is not showing high RPMs at High speed settings, and may be defective. The power supply fans were designed by a different team, and may not have the same controls.
    What SMC Fan Control and similar software allows you to do is put a new Floor under the fan speeds. They will spin faster at idle, and it is possible they may move up to even higher speeds more slowly. What is does NOT allow you to do is any actual reduction in minimum fan speeds, regardless of whether it allows you to set lower numbers.
    When the numbers get extremely large, the magnitude bits overflow into what is sometimes considered the sign bit. That has no meaning in this context -- all numbers should be treated as positive numbers. That probably indicates they took a shortcut and used general-purpose routines for signed numbers that were lying around instead of writing more correct versions for positive numbers from scratch.

  • Where can I get a replacement case fan for a HP Pavillion 180t

    The case fan on my 5 year old HP Pavillion 180t has begun to make noise when running.  This is the fan mounted to the back of the case, drawing air over the CPU cooling stack. From what I can gather from the HP support site, this model is no longer supported. I need to know the specifics for the fan in order to find a replacement. I would hate to have to purchase another PC because a $20.00 fan was failing. Thanks 

    The rear mounted fan is commonly called the System Fan. As a reference, it's model number and pic can be found here.  The fan is a 3 wire 92mm x 92mm x25mm case can.  Amazon price is lower.

  • I replaced the case fan on my XPS 8700 and things are much quieter.

    I added a new case fan to one of our 8700s.
    http://www.amazon.com/gp/product/B006ISKYPE
    Pro's - it is quiet
    Con's - the color scheme is ugly, but I'm the only one that looks inside my case so it doesn't bother me.
    The system is noticeably quieter as this rear case fan is much quieter than the OEM case fan.
    With an updated PSU and graphics card, the only sound after boot is is the CPU fan, and the occasional clunk from the HDD.
    The aftermarket PSU (Seasonic x-650) fan doesn't spin until it gets hot -- which is never so it is silent.
    The graphics card fans (MSI GTX 760 TF) are very quiet.
    Now, on to a quieter CPU cooler if that is possible with the Dell MoBo.

    You can also go here: http://www-307.ibm.com/pc/support/site.wss/product​.do?template=/onlineassistant/submitAQuestion.vm&s​... and submit a service request and just complain through that route.  Use the link NOT to service your lappy but to complain and make them do more work to contact you and send out a box and ship them back nothing, LOL - waste their shipping money.
    Oh hey, maybe this is where you send the pile of dog poo.

  • Case Fan Running at Full Speed

    I accidentally shorted the case fan circuitry on my HP motherboard (explanation below) and now the fan runs at full speed all the time. Other than the fact that is was a stupid thing to do, will it be a problem long-term and should I try to reset the fan speed switch?
    (Long Version) It is hot around here these days and my computer fans seemed underpowered. I put a splitter on the case fan outlet on the motherboard and added a second fan in addition to the original fan. It all worked fine except the new fan seemed to run pretty slow. I wanted to get a voltage reading from the fan plug but I accidently touched the two sensors on my volt meter and the computer immediately shut down. It started up and worked fine except the throttle was no longer working and the fans were running at full speed. This also explained why the second fan was running slowly before when they were both being throttled.
    I guess in the end I got my wish to have my fans running at full power, I just wanted to see if there will be any future problems leaving it this way.
    This question was solved.
    View Solution.

    Hello design_guy,
    You should not have any problems with the fans running at full speed other than the fact you may decrease the life cycle of the fan.
    You may want to install some software on the computer that will allow you to adjust the fan speed from the computer which may help you prolong the life of the fans and give you a little control over them.
    Something like SpeedFan should do the trick.

  • Cant see or control case fans on MSI board

    I just upgraded my PC to Devils Canyon and h87-g41 pc mate. Everything is working fine... except i cant see my installed case fans and they are running on max (i assume) and making a lot of noise.
    The very old board i upgraded from had option in bios for automatic fan control under overclocking (if i remember correctly). I set it to automatic and case fans were controled based on temperatures.
    But the new msi board cant detect them correctly. SPeedfan and cpuid hwmonitor does not show them, and they are not show in bios. And i cant seem to find any settings for case fans.
    Only fan it detects is the aux fan at the back of the fan and controls it automatically.
    I used Live Updater and did total install, so i should have all the drivers.
    I plugged them in right, used the pins and not the molex.

    On your board, CPUfan1, CPUfan2, and Sysfan1, are the only fan headers that are setup for sensing, the other two are 3 pin headers and very likely have no sensor on them.... as far as BIOS or any software are concerned, they simply are not there, if you need them controlled, you might have to buy a fan controller.
    You could plug one of your case fans into CPUfan2, if that header is not being used, and then you would have full sensing and control of it.

  • Case fans ? Air in or out (Case suggestions ?)

    Maybe this is a stupid question.
    But because of my high CPU temps i was beginning to think that maybe i had installed all my fans the wrong way 
    About case fans. Should they be installed so they draw cold air into the case or push hot air out ?
    I ask because i was in another Dansih forum where thay was talking about a new case with a 125cm (Big) slow fan in the side,
    and the guys said it should draw cold air into the case instead of pushing hot air out...  mmm
    Normally hot air should be pushed out, right ???  or
    Second. How can you if the fan blow or sucks air ?

    I have a windowed case, so when I see some dust in the window, I do open the case and clean everything that have dust, and this is every 2 weeks, or less... :D
    I understand that if you have overpressure inside the case and use filters with every fan, in the same period of time you will end with less dust inside than with underpressure, because the air will not enter through every hole of the case, but if you do not use filters (as I don't) the resulting dust in the case will be more or less the same.
    I don't like filters because they greatly reduce the airflow produced by the fans, so I prefer to clean the case more often.
    And about "getting as much hot air out of the box as possible", I have to say that I've tried with a big 38 x 120 mm rear exhaust fan of 103 CFM (the noise was unbereable !!) and the case temperature was the same as with the stock 25 x 120 mm fan that has much lower CFM, so every solution has its limits. I think that is very important to extract the hot air from the case, but nothing is more efficient than a direct and fresh airflow over the device to cool. I have 2 x 80 mm front fans that flows directly over my two hard drives, and they are currently at 29 and 24 ºC (the Samsung is amazingly cool), and even in summer the temperatures are barely higher.
    Anyway is very difficult to find the best setup with a given case/fans configuration. I have another 80m fan in the side window, and when I've inverted the airflow (stock was in exhaust mode) the processor temperature dropped 2 ºC, but in the same time the motherboard temperature unexpectedly raised 2 ºC. I leave the side fan flowing air inside the case, but I can't understand why the motherboard temperature is higher.

    When the fan's 3-pin connector is plugged into (PC) motherboards, the yellow wire provides the fan speed (RPMs). In the event that I might use it at a later time, I usually cut off the yellow wire near the connector, and then tape the end of it.

  • Case fans

    Could someone tell me why in BIOS the temp corresponds with the correct fans, but PC Alert 4 and other software temp monitors list the CPU fan as the PS fan. I made sure the CPU fan connector was connected to the MOBO connector labeled CPUFAN1, rear case fan was plugged into PSFAN1, and front case fan plugged into SYSFAN1.
    Which one is correct? BIOS/manual or software? Since some of these software can adjust fan speed automatically based on temp, it could cause serious problems.

    Fan1: 3013RPM (Intake) 'newly added'
    Temp2: 52C (CPU)
    Temp1: 36C (Board)
    Does this mean if Temp2 gets too hot SpeedFan will adjust Fan2? or all fan speeds? I thought fan # and temp # corresponds with each other.
    Fan speeds fluctuates but I never notice SpeedFan delibrately slow down the fan speed (low pitched noise instead of high pitch from case). Automatic Fan Speed is checked.

  • Case fan installation

    I have a Tsunami case and there is a front and rear fan. Both have motherboard and molex connectors. Frome what I can tell, the case fan should be connected to the SYS_FAN plug. Where does the front fan connect? What is the PWR_FAN connector for? Also, I am still struggling with OS installation issues so my PC use has been limited to the BIOS, but thus far, none of the case fans have turned on. I have seen some posts online that say that the mobo connector is for speed control and that the molex still needs to be used for power. Another post seems to hint at the fact that power can be obtained via the mobo connector and that the molex connector is not needed. So, what's the scoop for these fans? Where do I plug them into the board and how do they get power? Thanks in advance.

    I am guessing that you are using a power supply that has internal sensors for its own fan control...
    Most people people connect the case fans to the motherboard jacks
    So hook up the rear fan to the PWR_FAN jack
    Hook up the front fan to the SYS_FAN jack
    And if you have a side panel fan( some Thermaltake cases do), hook that one up to the NB_FAN jack
    The 8 pin JPW supplies power to the CPU, you MUST connect that from your power supply..
    The fan jack next to it, CPU_FAN is to supply power (and sometimes speed control) to your cpu fan...
    Connect the 24pin ATX to your power supply
    Also connect the the molex power jack (JPWR) to your power supply..
    Basically hook up everything that has a power jack with the proper power from your power supply...
    The case fans should come on when you click the power button on your case.
    Note: some people hook up fans differently (myself included) but the above set up is typical...
    Be safe...

  • Using NB fan connector for case fan?

    Seeing as the only fan supplies that support fan control are the CPU and NB, if I'm using a Zalman cooler instead of a NB fan to cool the chipset, is it possible to utilise the spare NB fan connector for one of the case fans?
    Or is that a silly idea because the speed of the fan will be dictated by the temperature of the NB chipset which may or may not enable sufficient case cooling?
    Has anyone tried this?

    In actual fact I have 7 x 80mm Cooler Master Fans in my system. 2 in the back, 2 in the front, 2 on the CPU (Hyper6) and 1 on the clear side door. All fans are the CoolerMaster Blue LED type and spin no faster than 2600RPMs. I never slow down the CPU fans ..... system is always on and always doing something stressfull   but using Speedfan or CoreCenter I can slow both fans on the CPU down to 20%.
    4 of the fans are powered through the mainboard (through PSU) and the other 3 using the PSU molex power connectors (not the FAN_ONLY connectors .... not enough juice  ).

  • [865PE/G Neo2 Series] Installing Case Fans

    Hi,
    This is probably the most silly post ever made on this forum  , but I need to know if it matters which way round case fans are fitted...
    are they supposed to suck air in or blow air out ?
    Feel free to laugh at my expense...lol
    bOO2

    No worries. Nothing to be laughing at as alot of people are confused about airflow as well.
    I'll always recommend active exhaust and passive intake over active intake and passive exhaust which I've mentioned in many posts here in the forum.
    You've to see whether the fans are of the same model and if they are, I'll recommend 3 fans cooling system or4 fans cooling system.
    3 Fans system: 1 fan blowing into the chassis which is directly placed near the CPU area to enhance CPU cooling, 2 fans at the rear to exhaust out all warm air immediately. If your chassis have a topblower hole, fix 1 fan at the rear and 1 fan at the top blowing warm air out.
    4 Fans system: Everything will be like the 3 Fan system. Just add the additional fan near the GPU and the HDDs area to cool them down.
    More airflow out will prevent trapped warm air stuck inside the chassis which is better than more airflow in.
