Pci exhaust fan

just got myself a pci exhaust fan,its only a cheapish one and i know its not the best for cooling but since ive installed it my case temp has dropped about 3-4c an my cpu temp has dropped about 2c so not to bad i think for very little money
anyone else have one ov these?

they move quite a bit of air but no matter what brand the bearings tend to go out of them pretty quick. Also a trick i learned is get 2 put 1 in the PCI slot below the VGA card and on the 2nd PCI fan take off the metal clip and flip it around so that its now upside down and put in slot above VGA (if you can) that way your VGA has air being sucked off both sides. It cools your VGA huge amounts and also does not let any heat from VGA get anywhere in your case to raise case temps.

Is there a way to trigger the exhaust fan during video chat?

The exhaust fan usually works during say...youtube videos or other activities that heat the laptop up, but it never comes on during skype video chats. This makes the laptop extremely hot. Is there a particular reason it doesn't turn on to prevent overheating?

Install smcFanControl to manually adjust fan speeds.

Removal of Rear Exhaust Fans / Vents

Hello all,
I am wondering if or how I can check the interior cleanliness of my Macs' Rear Exhaust Fans / Vents - including the correct procedure for the removal & replacement of the fan unit, if it is possible to do so ?
Would really appreciate any advice ! A shiny green star awaits awarding !
Many thanks in advance for your Mac expertise !

Hi-
A really nice guide, including pictures of the dust recovered from the interior, is Here.

Permissable to install PCI slot fan + another fan?

Hello,
I decided to do something to help get some of the heat out of my G5 Quad. I took from my G4 MDD the PCI slot fan which fits perfectly in the groove next to the PCIe slot. Also, decided to install a smaller fan in the middle of the computer chassis, next to the GPU. Is it normal for the G5 Quad's GPU card to get hot or warm? I felt the heatsink and it was kind of hot. I have no problems with my computer, just wanted to know if its permissable to put some fans inside the G5 to help get hot air out of the system. I know there is an air deflector shield, but is it any harm to put a small fan sitting upright facing towards the back to get hot air out of the machine, and a PCI fan card as well?
Awaiting responses.

Japamac,
For someone who doesn't own a G5, you sure do know a lot about them So, you are advising me NOT to put in a PCI Slot fan and or take the smaller fan from my MDD and put it in the middle of the case for it to cool the video card? I was just concerned because I saw the GPU temp was over 160 degrees and the heatsink, though massive on the 6600 nvidia was kind of hot to touch. I would have thought by putting in a PCI Slot fan it would help to cool the GPU down. It does in fact cool it down tremendously.
Perhaps, I will remove the other smaller fan. What is the purpose of the air deflector shield? I never had one of those in my MDD before and its a first on the G5. I am aware that PCI isn't compatible with PCIe. The PCI Slot fan doesn't fit INTO the slot, but rather just connects to the bottom of the slot. I know. G5's are not forgiving. Just the slightest miscalculation and problems can occur.
Is 160 degrees F exceeding the GPU temperature? Bear in mind, its the heatsink that got hot, not the outer perimeter of the card. Right now, my temps are as follows, even with the fans I have in place:
Hard drive: 115F
CPU A core 1: 122F
CPU A core 2: 124F
CPU B core 1: 124F
CPU B core 2: 126F
Backside: 117F
Drive bay(empty one?): 92F
GPU(video card): 128F
Also, I asked you another question in another thread. What internal SATA card can you recommend for me which supports booting to the OS? I just ordered a 500GB SATA-II drive and would like to access the 3.0GB/SEC speed with a nice SATA-II card that supports booting. I have yet to find one in PCIe. I take it there probably doesn't exist one.

Cold MBP, exhaust fan running full speed

Hello,
My 3mo old MBP exhaust fan has started running full speed (6200rpm), no processes or heat are to blame.
iStat pro say's the fan is currently at 6196rpm, highest temp sensor is at 30 degrees C.
Process monitoring says kernel_task using 160% of my two cores (interrupts?), this is a cause or a effect.
Reseting SMC had no improvement (unsure if I've managed to do correctly). Appart from that the machine works, very slowly, noisy, and very cold on my laps.
I'm on a business trip, don't have the diagnostic CD with me...
Any ideas so I can at least work during this trip ?
Thanks for your help, and for these forums.

Hello folks,
I'm in the same situation, the only difference is my hardware from 2006:
Model Name: MacBook Pro
Model Identifier: MacBookPro1,2
Processor Name: Intel Core Duo
Processor Speed: 2,16 GHz
After running the ASD, I got this:
+Temp Sensor - Palm rest L test 1 - Sensor Reads Within Operating Range.+
+-Check to ensure that sensor reads within operating range.+
+ERROR - Unable to read sensor+
+- T E S T F A I L E D -+
The sensor code is the same one from the post above: Ts0P.
So now, after looking for more than 4 hours on the internet, I couldn't find a clue.
What exactly is the location of this sensor?
Can someone please post a picture?
How can i fix this?
Thanks for everybody.

Exhaust fans not spinning

hi,
i moved my g5 the other day, and i noticed the fans at the back are not spinning. i think they're the exhaust fans. i looked in hardware monitor and ot says they are. but i can see they're not.
anyone have any ideas?
cheers

sorry, just being a ****! realized that those blade looking things aren't the fans. and the fans are spinning.
sorry!

Exhaust Fan not turning on.

Could someone please tell me how to turn on my exhaust fan?? My MB is running at about constant 55℃, which is normal, but I ran the yes>/dev/null and it was up over 110℃ with CPU idle% usage of 47% and still no fan turned on. It used to come on all the time while I was watching videos etc and now - nothing. I've recently had the logic board replaced - coincidence?
smcFanControl is installed - no effect.
FanControl 2.1 is installed - no effect.
iStat is installed for monitoring - exhaust fan reads 0rpm.
Help!!
Thanks.

I would take it in to Apple.

Exhaust fan

hi, just have a question: as soon as i open my macbook pro the exhaust fan turns on. its not loud or anything in fact the only way to hear it is to put your ear to the macbook but i just wanted to know if its normal.i have istats widget thats showing me that all temps are normal and exhaust fan running about 2000 rpm. i checked activity monitor and nothing unusual there and i also did ram and power management resets. again i just want to make sure that its normal for the fan always be on.
thanks

I recommend using the iStat Pro dashboard widget to monitor the exhaust fan speeds. The two in my i5 MBP are only audible when they reach ~4000rpm which usually happens when both physical cores are at >90%. With one core at 100% they both stay at ~3400rpm and the cpu at 71C.

Macbook pro's exhaust fan

My macbook pro's exhaust fan has never came on since I have owned the computer, then suddenly is came on at full speed during boot up and now its off again?

Are there any fans other than the exaust fan cause I have "fan control" and it normally reads a temp around 120 F and a left and right fan speed of 2000 rpm but when it went haywire it said the temp was 32 F and -1 rpms. I do hear the fans running normally, like now, hhbut they are very small sounding. The fan I heard when there was a problem sounded completely different, it was moving a huge volume of air.

CPU A's intake/exhaust fan stuck at 300 RPMs

Hi all,
As I write this post I'm waiting for iMovie 08 to shunt a project to the media browser so that iDVD can use it (oh it'll just be another 210 minutes or so). The fans in my DP 2.0 G5 are a-blowin' but imagine my surprise upon firing up Hardware Monitor:
CPU A: Intake Fan:*300 RPM* - Exhaust Fan: *300 RPM* - Die Temp 60.5 C - Current: 28.93 A
CPU B: Intake Fan: *2731 RPM* - Exhaust Fan: *2780 RPM* - Die Temp: 73.1 C - Current: 31.85 A
Activity monitor shows both CPUs working, unless I'm misinterpreting the info,
Once iMovie done I'll run AHT but can I assume that perhaps the sensor and/or fans are defective? Perhaps the CPU itself?
Thanks for any guidance,
Frank

Macbook May 2010 edition exhaust fan runs at full speed

Bought a new Macbook around February 2011. Yesterday all of a sudden while watching Netflix, the exhaust fan started running at full speed (Approximately 6200 RPM). I thought the machine was overheating. So I immediately shut it down and let it cool. But I noticed the machine was barely warm.
When I started it up again, it started making the same noise with the exhaust fan running at full speed. I installed SMCFanControl and I see that the CPU is barely warm - 35-37C and yet the fan is running at full speed. I looked at the CPU/HDD usage and there is barely ANY usage (~90% idle). Nothing out of the ordinary. So it definitely doesn't seem to be a heating issue.
In order to troubleshoot this I have done the following:
1. Installed latest upgrade - Snow Leopard 10.6.7
2. Reset SMC
3. Reset the PRAM
4. Tried booting from the install DVD. There as well it exhibits the same issue.
Neither of these steps have helped me with my situation. I would really hate to go to the apple store as its always crowded and would end up wasting time. Are there any other steps I could try?
Update: I tried running the Apple Hardware Test from the DVD. This is the error code that I got: 4SNS/1/40000001: TN1D- -1.000
Can someone please tell me what this means?

I don't know what that code means for sure, but it sounds like one of the temperature sensors may have died, so the fans just run at full to cool.
I would take it to the apple store.

Exhaust fan overworked when system idle

Any idea as to why my exhaust is freaking out when the system is idle. I turn it on and in a matter of 10 minutes after ONLY checking e-mail the fan is at 6000 rpm. The system seems to be overworking itself unnecessarily. CPU shows the following in istat:
User: 22-30%
System: 27-34%
Nice: 0%
Idle: 48-51%
CPU temp is at 68%
I have a Best Buy warranty and they say it passes all ASD tests. This fan is draining my battery 10 times faster than before. Any thoughts?

Go to your Utilities folder and start Activity Monitor....select the CPU tab and choose 'All Processes' from the drop down menu at the top of the window....I suspect you have a stuck processes....you can click the stop sign and kill it from there....

Exhaust fan not spinning

hi,
recently my mac's been overheating, catastrophically, it causes crashes, freezes etc. during high processing situations.
iStat pro can show fan rpm's on both sides, the one on the left is fine - often running at 7000rpm,
but the one on the right is always 0rpm, and i cant hear this fan spin either, so i trust iStat's result.
i've seen many discussions on fans not working in these 15" powerbooks.....any solutions out there?

Welcome to the Apple discussions.
While it looks pretty conclusive the right fan isn't working, I would still run the Apple hardware test to confirm ... it does turn the fans on and off during the test.
In terms of fix, you can try resetting the power management unit (PMU): http://support.apple.com/kb/HT1431 . No guarantee this will fix it, however, won't hurt either.
If that didn't fix it, then you need to replace the fan. If you have AppleCare, let Apple take care of it. Otherwise, you could take it to an Apple store for repair or an Authorized service center, which can be found in the US at http://www.apple.com/buy/locator/service/ . Or if you're familiar around a computer, you can replace it yourself. Instructions for replacing the right fan on the 1.5/1.67 low res system are at http://www.ifixit.com/Guide/Mac/PowerBook-G4-Al-15-Inch-1-5-1-67-BT-2-0-LR/Right -Fan/64/20/

Refurbished X230 exhaust fan alignment, is this right?

Yall,
I just got this refurbished x230 from the outlet. I may be paranoid, but the fan "thingy" appears to be imperfectly aligned. I can see a little bit of foam. Is this normal?

Thanks. Appreciate the insight, I learned a lot about thinkpads from this site already.
1st post here

It's just a spacer
It's not blocking the air flow
The fans only go in one way
Could always open it up and remove it

K7N2 Delta ISLR and XP3200 Woes

Let me share some of my experience with random crashes and lock ups on my main system.
Hopefully some might find it helpful and others might have useful comments to add.
It all started when I decided to upgrade my system. I waited until new technology was announced and then went out and bought the hardware that was knocked off the top spot.
My current system is:
Althon XP3200 Barton
1Gig PC3200 (2x512M)
K7N2 Delta ISLR Bios 7.7
Radeon 9700pro
Antec TruePower 550W PSU
XP Professional
SATA 120G Barracuda
When I first assembled the system I could not, and still cannot, get it to run stable as a XP3200 with a FSB of 200MHz (400MHz) and the memory in dual channel mode. The system wouldn’t boot, would randomly crash, would come up with fatal XP errors.
So after consulting the message boards I was informed it was probably be down to two causes; a inadequate power supply or overheating.
That is when I went out and bought the Antec TruePower 550W PSU. The reason being the CPU temperature was around 47C - 52C (107F - 115F) with ambient around 35C (88F). Not too hot I thought.
Anyway this did not solve the problem so I then decided to change the CPU coolers. I now have a nice collection, Alaska, Aero, Gigabyte and others. Current one on order is SLK-900A with a delta FFB0912EHE fan. But again this did not solve the problem.
I then thought that maybe the ambient inside temperature was too high and therefore pushing the CPU temperature up. To solve this I fitted two hard-drive fans, four 80mm case fans and a PCI exhaust fan. This was on top of the 3 fans already in the system. Still the system would not run. I even took the side panel off and had a 6” mains fan blowing into the case. Still couldn’t make it stable.
I have just ordered a Thermaltake Wingo V8000A case.
So I decided to check out the XP3200 and memory. After playing around I found out that:
1. The memory is fine running dual channel at 400MHz. I ran memtest using my CPU and memory in a friends PC for 12 hours without any problems (Abit board).
2. The system is stable if I drop the FSB to the processor to 166MHz (333MHz). How I am currently run the machine.
3. The system was more stable if I ran the memory in single channel mode.
4. The point it becomes unstable is when the CPU FSB is 192MHz (384Mhz).
5. The problem occurs on another K7N2 Delta ISLR motherboard. Actually exactly the same problem running a different XP3200 and 1Gig.
I have tried all possible combinations in the bios, except Vcore, Vddim voltage levels. Which is my next step. I think I need to up the Vcore at higher frequencies as I believe it may be a bios /motherboard inherent problem.
I hope this might be helpful to some who are experiencing the sample problems.
Couple of things I don’t like about the mother generally a part from the fact I can’t set it up correctly.
1. The decoupling capacitors around the CPU socket are too close. This limits the choice of CPU coolers you can fit.
2. Motherboard components interfere / prevent you from fitting certain cards in the PCI slots. Such as the SPDF adapter that comes with the motherboard.
And does anyone know:
1. What is the maximum temperature I should be seeing for stable operation on a XP3200?
2. Any recommendations on another suitable motherboard? I basically spent all the money I had so if I can’t get it working I’ll bin the motherboard and buy another one.
Oh, why don't I run it at 333MHz? Well then I got a slower system than I started with and it means I admit defeat!

I have this same board with the same BIOS and am also using an Athlon XP 3200+ (with Corsair TWINX1024-3200C2 RAM) and had the same excruciating stability problems. I had tried/tested everything in sight and no stability. Then I found a posting in this forum made a few months back by WebFan (with an XP 3200+ and basically the same RAM), who said he had the same kind of problem. He had only achieved stability when he reduced the FSB setting to 192 MHz (obviously not a coincidence). (Thank you ever so much WebFan.) I reached the heaven of stability by making the same change. Then I started experimenting; I moved the bus speed to 193, still okay. I set the RAM settings to the 3-3-6 2.5 that Corsair says are stable, still okay.
Then, and this I believe is the key step, I installed the lastest set of chipset drivers from nVidia (not the older version provided by MSI). This change subjectively seemed to improve performance noticeably, so I decided to take the big plunge and return the FSB to the rated 200 MHz setting. It's only been three days, but STILL OKAY! Before setting the FSB to 192, I was having all kinds of blue-screen crashes numerous times a day. I haven't had a single one in ten days, three days running at the full 200 MHz.
It seems to me that the board/chipset were not tuned to handle the 3200+. If you look at the description of the board on the MSI global site, it says it's compatible with Athlon XP 3000+ and up. My guess is that only the lastest edition of the drivers, version 4.24/4.27, is up to the job. (I'm not interested in overclocking and so haven't been interested in seeing if I can do better than the rated 200 MHz setting [400 MHz DDR clock speed]. Leave well enough alone, if you ask me.)
Try them; you have nothing to lose but your instability.
