Am I the only one that finds that CoreDuoTemp and iStat reports inaccurate temps? Temps that never change or are lower than physically possible?

uhhhh.................... stupid me

I deleted tht app and now my fans never stop.......... HELP ME! Please

Reinstall the app...... Or shut the computer off. Then turn it back on as it resets the SMC data the program changes.

If you haven't installed the latest firmware for your computer, then CoreDuoTemp and iStat/Pro cannot read the temperature correctly.

Dude, last time I checked your thread was about editing files of OS X. This is different.
Obviously you did not read the thread.....From trying it out it looks like somebody put a GUI on those same script files and then posted it. It might have been nice if this was mentioned at the beginning as being leveraged off that thread........However; No Offense is to the Programmer or anybody else!

The difference would be that that I would never have bothered to implement the changes Rokem mentioned 'as is'. Now this program is available I'm using it. So thanks to both people - although as the guy who actually developed the app, Hendrik is the person I've contributed to.

Shame about the lack of fan adapt, although it does seem to have a limited degree of adaptation. Perhaps the Core Duo Temp and this app's authors can get together to produce a fully controllable adaptive fan app.

Of course, being slightly amazed I can press the function and eject key without getting burned now is a sign that I too have been got at a little by the Jobs Reality Distortion Field. It's only when I return to the Core Duo HP, Dell and Sonys all of which stay merely warm under most situations that I aim a contemptuous snort at the MBP for making me think that way.

At first, my new MBP scared me it got so hot, but after a while and a firm/software update or two later, power management improved a little. Finally realized that it now runs HOT only when maxxed out, which rarely happens on battery and in my lap.

This new app smcFanControl is most welcome, tho as I can now pick up my MBP after it's been sitting, running BOINC and not get burned.

Big thanks to Hendrik for writing the GUI for all those scripts that showed up after 10.4.8. I love having a cool MBP and don't even notice the increase in noise - it's a lot quieter than my desktop, a G5DP2 with 3 external HDDs.

This is a very good app, reduces my reported temperatures by 5-8 C.

About the battery life: Yes, obviously it will decrease battery life since fans require power. At 4000 rpm with Firefox, Adium, Mail, and the program itself running with a maximum charge, my battery says it will last 3 hours 31 minutes. Without the fan, 3 hrs 44 min.

The real obvious difference is case temperature. Running at 3500rpm it is very audible but the MBP is actually merely warm to the touch instead of 'ouch'. So much for 'it just works...' more like 'it just burns... until someone gets fed up and hacks it'. ;)

Which firmware are you talking about? If you mean the SMC firmware, I've already installed that.

CoreDuoTemp shows a tempearture inferior at 30 degrees Celsius, which is clearly wrong ?
Sorry, no solution is possible, it's a bug of Intel ! A restart can repair that failure.

I have the same problem. Installed the newest firmware when it was released, but ministat doesnt give a fan speed readout.

I have a week 40 MacBook, and find the temperature fine, even when it's on my lap, while running iTunes, Camino, Transmission, Dashboard, Finder and other light apps it never gets 'hot'.

It certainly gets relatively warm, but nothing that causes discomfort.

I had to run the default script again and they ramped up normally.
What script is that? I've tried restarting the computer, but the fans don't kick in normally now. It still runs on the modified SMC data

Yesterday I played with smcFanControl, the app. As the day wore on, I saw a lot of positive feedback about Fan Control, the preference pane, so I loaded it. More adjustability, but a lower max fan speed. Tried to go back to smcFanControl, but can't. At least for now, I have a much cooler MBP -

Thanks to everybody working on this.

What's the need for this? My fans go on when they need to, and if they don't, I'd rather they be off. My MacBook case is cool right now. The fans now go on before my case even gets hot, and this was done by Apple's 10.4.8 update.

I guess I'll keep this app in mind if things ever go screwy, but right now, I don't see the need. Not sure about MBP owners, though. :confused:

Well, this sucks. I downloaded this app, uninstalled it, and now my fans always stay on at the minimum settings. The worst part is I can't remember if my fans always stayed on at low RPM because I can hear them quietly in the background.

Just having a look through the Apple Discussion Board topics on this (where the creator of smcFanControl posts updates), am I right in saying that the program just alters the MINIMUM settings of the fan, but the normal stuff still applies, i.e., when it heats up the fans will still ramp up, then back down?

Cheers, Karl

The script from the Apple Discussion Board chanfes the minimum fan speed. I have tested it and the fan speed did increase when running something processor intensive.

the fans in the MB or MBP should be able to handle running close to full blast. if the fan's keep breaking down then the motors they use for them are cheap. Apple should address this issue when they see this happening to people trying to find a way to make the fans do what they are suppose to do in the first place.

I know nothing will last forever but the fan's is one thing that should take a beating and ask for more, and Apple should have seen this they should have put high quality fans in these system's and make them do what they was intended for.

i give congrats to the people that was involved doing what apple should have done to begin with. thanks for showing Apple what the fans are suppose to do, keep the system cool

i haven't seen a laptop/notebook or what ever you want to call this system get so close to burn some one like the MBP does,

This program reduces operation temperature at the cost of permanent noise. Useless for me, as I like my computers cool and quiet. I'll stay with speedit and underclock my CPU to 1GHz permanently. No more fan noise and cooler than ever :)

when I run yes > /dev/null twice and get both cores maxed, my temp goes up to 90C and stays there... smbfancontrol reports both fans ramping up to only 2800 RPM or so... is there something wrong with this situation?

Tons of people love smcFanControl, and that's fine. But just trust me on this (because I don't wanna type out the full reason again, it's already in 30 other threads), if you leave your MBP sitting around while you leave, don't think about leaving it running with this software. There are plenty of good stories, but plenty of scary ones as well (I reached 200F, no details needed). There is a program called FanControl that is much better for this problem. smcFanControl just alters your minimum fan speed, and if something happens to go wrong, then that's it...it doesn't monitor anything. FanControl monitors your temp at all times & adjusts the fans by itself when necessary (I know smcFanControl is supposed to leave the auto settings in place, but my balls have a different story to tell).
