MacBook Pro :: SMCFanControl - Quiting Doesn't Reset Fan Speeds?
Dec 9, 2009
I have a macbook pro, intel 2.4ghz core 2 duo, running snow leopard.My default speed for smcfancontrol is set to 4000rpm for both fans. I turn it on when i feel things are gettin a bit hot and I dont have my laptop cooler fan underneath.
I noticed something, when I quit smcfancontrol, shouldnt the fans revert back to default speed? I checked with iStatpro and saw that, even after quitting smc, the speeds of the fans are still at 4000rpm.After doing an SMC Reset, the default fan speed as stated by iStatpro is 2000rpm. As soon as I fire up smcfancontrol and quit it right after, the fans stay at 4000rpm. Even after i power cycle (reboot & power off/on) the mbp, the fans are still stuck at 4000rpm.
I feel this will wear out my fans a lot faster, I hardly ever need the fans at faster than 2000rpm because I use a laptop cooler 90% of the time.Is this a normal issue? Or a bug? Anyone else have this problem?

I saw an interesting post today by pgharavi who says he is using SMCFanControl to set the max speed of his fan to 4000RPM:Quote:From the terminal:
/Applications/smcFanControl.app/Contents/Resources/smc -k F0Mx -w 60e0
(that's the default 6200 RPM)
/Applications/smcFanControl.app/Contents/Resources/smc -k F0Mx -w 3e80
(That's 4000 RPM Max)
I obviously gain a few degrees C when limiting to 4000, but at least my MBA shuts up.Not to question his knowledge but have others tried this and does it really work? might not go so far as to set the fan to 4000 (but I might). Given all the thoughts on Coolbook, what do you all know/think about this? Safe and effective relief from fan headaches?

Just bought a new base 15" MBP, running 10.6.2. At a glance, everything runs just fine. However, SMCFanControl 2.2.2 can only read "LeftSide Fan". As if the Right Side Fan doesn't exist.
Well, it could be that the app is at fault, but I worry if there is a hardware problem. Is there any quick way to check whether the right side fan is ok? (while running apple hardware test, I can hear both fans working). I don't live anywhere near Apple Stores or their related service center, so if there's any app to verify the right side fan,

I keep getting these error messages when Safari keeps quitting. I have Safari 3.2.1 and OS X 10.5.6. I have performed resets, I empty my cache and clear my history often. It seems to be getting worse. The programs get the beach ball and then everything just quits running. 99% of the time I am getting the bad access, kern protection failure message. Is there something I cna do to fix it or prevent it?

Does smcFanControl would able to control the fan at same rpm before boot up into vista? When I changed the rpm of fan to higher (3,000 rpm) under Mac OS X then boot up into Vista then it would be same rpm (3,000 rpm) what I was set or force back to default (back to 1,200 rpm)?

I'm just wondering if there is a bandwidth monitor widget that doesn't reset itself on a reboot. I feel like I've tried hundreds from the Apple widget download page, but all reset themselves. It's not vital that I know how much bandwidth I use as I've got unlimited broadband, but it would be interesting to see how much I get through in a week/month/year. Is there a monitor that will allow you to view the bandwidth on an IP address you specify? I want to be able to monitor all traffic coming in and out of my router, but I can't find an App that does this either. All they monitor is my local IP address 192.XXX.XXX.XXX (Specific to my iMac). I have a static IP address with my broadband so can I monitor traffic flowing through that? Or would I just need to monitor the routers network and/or broadcast address?

Using both smcFanControl and istat, I cannot get a reading on my fan speeds. I can hear my exhaust fan spinning, but these programs tell me it is always at 000 rpm. Also, I don't think the fan control is working, as I don't hear an increase in fan speed when I make adjustments.
Does anyone know how I can get these apps to recognize my exhaust fan?

I find 90% of the time I watch a YouTube video (standard def, normal sized) my MacBook gets hot and the fans spin up. Most of the time they'll go to ~4200rpm. Yet the other 10% of videos, I stay at 1800rpm and 50C. How is this possible? Both times I've just had Firefox open.

My girlfriend just got a new MacBook Pro and I've been helping her transfer software and such to her computer from my MacBook Pro. When I was transferring games to a USB 2.0 flash drive (it was only 25% full and it is 2GB), it was freezing up when transferring multiple things. So, I stopped everything, and transferred everything one at a time. Well, it took between 5-10 minutes to transfer a 50MB game! When I plugged the drive into her computer it took all but 30 seconds to transfer. Is this difference accounted for by the .14 GHz processor bump from my 2.26 to her 2.4? Or should I be concerned about this slow speed? My computer is little over a year old now and I've already had the logic board replaced.

I have this odd problem on my i5 MBP. When I have no external drives attached AJA System test reports my SSD speed at about 227mb/s read and write. When I plug in a USB external drive the SSD reports the same speed. When I plug in a FW800 drive the speeds jumo to 234 - 245mb/s. When I unplug the FW800 drive they go back down.

I'm beginning to wonder if Apple put a lousy Airport card in the new MBA. No matter what the wifi hotspot, I get downloads of 2MB. I just bought a new Airport Extreme at home and I really thought the MBA would be faster.
Am I missing something here? Do I have to "match up" the MBA with my Extreme to use the fast "N" connection? Or is there some network setting to tweak on the new MBA?

I have a new MBA (4GB), which I am very pleased with but I can't figure out why its wifi transfer speeds seem much slower than my Mac Pro. The MBA gets a max of about 250 kb/s while the Mac Pro gets over 1000. I'm wondering whether there's some adjustment that would speed up the MBA.

I am looking to buy my first mac in the coming months. I have found that the Air is quite appealing, with perhaps one flaw. The most extreme program I will be running will be Finale 2011. It comes with a sampling of Garritan Personal Orchestra. GPO's site lists the minimum requirement for the processor to be 1.8 GHz. Does this mean that the app will always need the full 1.8 in order to run well? I assume that it wouldn't. If anyone has any personal experience with this app, it would be great to know how it typically runs. The 13 inch Air comes with 1.86 Ghz. So, if I have email, internet, and basic things like that running in the background, will that Macbook Air run successfully?

So apparently every time I restart, iStat pops up annoyingly and tells me its now a paid program, and I don't want to pay for it. Are there any alternatives to see my CPU speeds and temperatures, also my memory usage in the top bar? I want something that I can always see.

So I've got a new 15 inch i7 MBP. SSD, 8 Gigs of ram.. it's awesome. The machine itself is insane. Crazy crazy fast. However, it's not nearly as fast in terms of WiFi speeds as my previous Macbook Pro. Using Unison to download usenet files, I was getting about 5 megs/second (I'm in Holland, our internet is crazy fast). With the new one, I'm getting about 500k/sec. I suppose it could be a coincidence and something could be wrong with the network, but it's been this way for days. Anyone have any idea what might be slowing things down? Could something be wrong, or would it just not work at all if that were the case? Hoping I don't have to send it in for service...

I download a lot of things and like high speeds, especially when I should be getting them.
The majority of the time my MacBook Pro downloads at about 1.7-1.8mb/s (as I have a 15MB/s internet service) which is terrific! I sit up in my room, a floor higher than the router and download away at great speeds.
But, if I go to download something on the Mini (and this only seems to be happening lately, oddly enough) it barely ever hits 1mb/s, is normally at 400-500kb/s and drops to as low as 90kb/s sometimes!
What can be done about this?

my macbook fan speeds up and is very loud when ever I play a clip on youtube or basically use my computer for more than one application. However after closing the video the fan returns to a lower RPM.
could it be that the fan is dirty and needs to be cleaned?

i have newish MBP and iMac. I also run several windows 7 based pc's. Over the last couple of weeks the download speed on both mac's has declined badly. Trying to download drivers for an HP printer yesterday and was downloading at around 25kbps on both macs, ended up downloading on windows pc at around 800kbps instead, same with any other downloads, was getting over 1.2mbps on windows last night whilst my macs struggle toexceed 30kbps making them almost unusale. I am a relative newcomer to apple, love build quality and feel but am nor too happy with this situation, have tried using different internet connections too - tethering to my cell, same result - 2 different machines so it seems to me the issue sits somewhere within Lion.Â

I have my 2011 17" macbook hooked up via a Moshi HDMI adapter to a 24" Acer 1080p monitor... While the image shows properly it makes the computer completely unuseable. I can't play videos and it lags up the machine really bad. I don't get it... i paid $3000+ for this machine and it can't output a smooth HDMI signal without crushing the system?

my laptop (macbook pro) doesn't turn on, because the battery doesn't work (may be because of moisture), and the 7 battery lights on the left side are off, and when I plug the charger in, the light on the magnetic socket turns on so dim ..

I have 2 WD Caviar Black drives that are installed in my Mac Pro. Both show the exact same part number in Disk Utility, both are less than half full, both verify fine with Disk Utility. However one shows 125-130 MB/s RW with AJA and the other only delivers 90 MB/s. What gives? Just a sub-standard drive? THey are in adjacent bays in the MP, used as is - nothing changed. They are OEM drives thru Amazon from a few months ago. Both were erased and formatted prior to putting them in the MP a few weeks ago.

The 64 bit 33MHZ PCI slots on a G4 are running at 133MBps correct? Also I want to know if all 4 of them are running fully inpendent from each other? So if I have a RAID card in there I can get the full 133MBps and will not be robbed of speed if I have a neighboring Firewire 800 or SATA RAID next to it.

Im here on a mission to find out why my macbook running snow leopard will only give me bang on 20mb download when every other windows machine in my house is giving me 50mb. I have tried to do a bit of google searching but don't seem to be getting anywhere. I assume it must be the macbook and not any router settings etc?
