i know fully cooked meat ball's ready to serve without doing much but sitting there with your MBP in lap
Got a tip for us?

My Macbook has a much cooler temperature with this new app!

smcFanControl is good for this. It DOES leave the auto settings in place, it just alters the min speed of the fans. Like. I have it at 3000rpm all the time now. A lot cooler etc, but when I do anything that requires processsor power or whatever, and it heats up, then the fans ramp up. Then go down again as they usually do, but only back down to 3000rpm. smcFanControl is great.
smcFanControl does keep my mb cooler, and I keep it at 3000 as well when its plugged in, but if it gets really hot (like when its in my lap) I ramp up the fan. I do recommend to turn the fan down when not plugged in because it eats up about 20 min of batter at 4000rpm. The program does not alter the basic auto settins for the fan.

Correct. However, when my MBP reached 200F and the fans never cranked up any higher, I was a bit worried. This hasn't happened to many people, but I've heard 0 reports of it from FanControl. And also, upping the minimum fan speed is great & all, but I think the common theory here is that obviously the automatic fan control system is lacking for the MBP. So while increasing the minimum fan speed makes great for when the laptop is idle, it does almost nothing to keep the system cooler than it normally would be once you start rendering a video, etc.
So to choose smcFanControl over FanControl, to me, would be choosing less capable software over more capable software (keep in mind, I have no affiliation with the software, I speak so highly of it because I use it and it works). And also, I see small chances of risk because smcFanControl does not monitor anything, and if your fan speed never increases for some reason, the software would never know. FanControl actually monitors your temperature & constantly adjusts based on that. I just don't see a reason to go with the other here.
the app shows that one of my fans stays at 0 all the time, no matter the load. A few people on the macnn forums seemed to have this problem too, and thought it was a hardware defect. Anyone else experiencing this?

I completely understand mate. For me though, and many other I guess, smcFanControl is the best as I just alter the minimum fan speed, and the Apple SMC carries on doing its thing is it normally would. Maybe perhaps you had a slight error or something? I couldn't begin to imagine, but all smcFanControl does is change the minumum fan speed in the Apple SMC. Thats all. It still does the rest itself. smcFanControl does not monitor the current temp, it exists only to change the speed the fan runs at, shall we say 'normally', and still lets it speed up when it needs to, and that's all a lot of people need, as it's made my MB a lot cooler running the fan at 2500-3000rpm all the time as opposed to 1500rpm.

Also, a reason I don't want to try FanControl is that it does measure the current temp and adjust the fan speed etc. 'Coz my MacBooks temp sensors/CPU has that annoying glitch that it only shows the temp that the comp boots at. The fans run when it gets hot etc like it should, so I guess it's a software glitch. And unless FanControl reads the sensors that the fans seem to use, then I'm sticking with smcFanControl.

Yeah...it is great for that. I just want to make sure that anyone who comes in here & may not be as technical as most of us has the right information in front of them. I'd hate for an average user to get into trouble with their fans & not realize it...it could be devastating for them. As all of these softwares or scripts could to be honest.
MalcolmJID said:
Yeah sounds like you're better off that way. Have you tried to get Apple to fix that though? I don't know if you do any big gaming or use a lot of pro applications so it may not matter to you, but I'd be a bit scared about not knowing the cpu temp.

thanks! Good to know I don't have a busted fan.
edit: after using the preference pane version for a while, I'm noticing that the preference pane is consistently reporting about 5 degrees Celsius higher than coreduotemp. Both are reporting significantly cooler temps than I see without the new fan settings, but I'm curious whether there is a way to know which is right.
also, why is there a "lower threshold" in the preference pane? If the macbook run at 30 degrees Celsius, that's fine with me. It's only overheating that I care about...

Yeah I'm not sure why the temp reads a little differently. It does that for me too. But I continue to monitor mine with CoreDuoTemp. And personally, I set both my thresholds at the lowest levels with my base speed at 2500rpm. I can't seem to force this thing to get any hotter than 60C (and even then it cools back down pretty quick).

The only game I play is RCT2 when I boot in Windows. I usually hear the fan blowing a bit when I play that. So at least I know the fans are working properly, it doesn't bother me enough to be without my MB for a week or two.
I just got my MB today, and with smcFanControl at 3000 rpm I'm at about 43C idle...is this about right? Or should I worry?
CoreDuoTemp vs. FanControl readings
I'm seeing very different readings from the two. When CoreDuoTemp reports 24C, FanControl (the one from http://lobotomo.com/products/FanControl/) reports 46C.
iStat and CoreDuoTemp agree with each other.
The thing I'm wondering is whether the apps are measuring the same thing. For example, could one be measuring the exhaust from the fan (which would of course be warm) and the other measuring the temperature of the chip itself?
Thoughts?

The fans are running, CPU running constantly at 60-80%, and the machine is warm, not hot. The same second the conversion finished (while writing this), the fans quit. CPU now running at 3-14%.
Go figure...
I hate to burst your bubble... but your temp sensors are busted if they're reading 19C, even at idle. It's simply not possible. That's 66 degree fahrenheit, which is about room temperature. Now, I'm not sure how much you know about physics... but unless your battery isn't going down, heat is being produced. 66 degrees is room temperature. The only way your CPU is running that cool is if it's not even on.
So in conclusion... wishful thinking, but your proper temperature reading (even with a good thermal paste app) is probably going to be around 60C-65C w/ a 50% load.

Uhm... not really - or, rather, the MacBook is working fine, but iStat/CoreDuoTemp report the initial value, and then don't budge. I've a week 39, with the latest firmware, so the problem is not there.
However, as mentioned two posts above, FanControl is reporting very reliable temperatures. I've been playing around with it the whole day, and a setting of 1700rpm, 45C min/80C max keeps everything nice, quiet and cool. When converting an avi to mp4, everything ramps up to full and approx 65-68C (a single peak at 72C), and then quickly down to 45-55C, depending on ambient.
So, it is working OK.
BTW: I was running a sensor on the exhaust, and its fluctuations correlated nicely with FanControl's readings, albeit at 10-12C higher (bearing in mind this was not exact, just to see whether the rises/falls reported by FanControl could be correlated).
I know there is an issue with the Intel chips and temperature readings, but I don't know if its been fixed yet.
Also, I hate to ask, but could someone e-mail me the FanControl program (I'm on a blocked internet and I can't access the page to download it). My e-mail is linkboy321@gmail.com.
I have smcFanControl, but I want to give the other program a try.
Thank you.

I'd say no, as the fans run within spec up to 6000/6200rom, so I'd say no. BUT, running them at full speed all the time will certainly do no good.
I'm also very pleased with v1.2 of smcFanControl as it reports the temp now, but from a sensor on the logic board, not the CPU one (as I have a CPU with the annoying temperature bug on it). Whooooo!
