With my 20.1" BenQ hooked up and with adium, safari, itunes, and transmission (downloading 3 torrents) I'm hovering around 53C, my Idle was always around 48-50, but it seems to keep cooler under loads now.

No, it will not fix heat.

What are you on about? Nearly everyone, including myself, are reporting dramatic temperature drops, both processor and actual case temps

[masugu]

So the big question is 10 degrees C a huge improvement???

Uh, yes, I would think that would be obvious.

Not so in my book. Seems like lots of other folks have much lower temps...Maybe I should ask if 62 degrees c is good for pumping to a monitor, a couple browser windows, word etc

Peoples temps vary, but if your asking if 10C (roughly 20F) temp drops are an improvement, that should be obvious.

Well what is average? If 60 degrees is still high, a 10 degree drop is not much.

60 is on the high end, but that doesn't make the 10C drop in temps any less of an improvement, just means your moving from 70 to 60 instead of 60 to 50 or whatever.

My idle temps havent changed at all, but under load its not raising up all that much now, which is what I think the update is meant to do.

[luckyjoe]

My MacBook arived on 15-August. It had the update from the factory. For the last four days I've been thinking that the upper left corner of the keyboard was (subjectively) hot. I also only installed CoreDuaTemp last night, so I have no data to compare. However, if people are seeing a 10dg.C drop with this update, I simply cannot imagine how hot those 'books were running!

I'll watch the temps over the next week and shoot the exterior with an IR thermometer when I feel it's really hot.

Maybe this can give you an idea. I would use my MacBook on a laptop desk sitting on my lap and after about 60 minutes I could feel some serious heat that had transfered from the MacBook to the laptop desk.

No problems like that now, in fact I used my MacBook on my lap Thursday night after applying the update for almost 2 hours and the heat was present but not uncomfortable.

[Photo678]

ok, this update really does help. my book is noticeably cooler, not sure about temps as i don't get into that type of stuff...but def. cooler.

as far as the moo, won't know until later today when im working, but it never really bothered me, it was hard to hear anyway.

GREAT JOB APPLE

[masugu]

Well, I still want more time to eval this fix when my MB is not hooked up to my monitor. I think it runs a fair bit cooler then. Yes. I guess 10 degrees is good....I was just hoping that whatever new temps we experience are more in line with other best of class laptops.

It was a scorcher completely unuseable on my lap for long periods of times. In fact I stopped using on my lap in fear of becoming unfertile.... jk

[luckyjoe]

Even with the update installed out-of-the-box, the table top will still pick up a lot of heat from my MB. As I said, I'll have to monitor the temps not that I have CoreDuoTemp...

[harrisjamieh]

How do you now it is installed out of the box? Have you run software update to check?

The information is available through System Profiler. SMC Version number should read 1.4f10.

[scattered]

Is the apparent average of 60 degrees you guys are talking about the C the F temperature? Because mine has been running around 20C all day today (altho I've only been doing some webrowsing) and yesterday before I applied the update it was in the 60C range.

60C before the update and 20C after the update? I assume that's a typo as even when my CPU is throttled back to 1.5GHz under light use, my cores are running around 50-55C (and the Macbook's SMART disk is around 32C).

[scattered]

Nope. Unless CoreDuoTemp isn't functioning right, it's been reading 20-22C all day. I only had it open briefly yesterday, but it was in the 60 range.

Could this mean something is wrong with my temperature sensors?

Even the second I turn my MacBook on, the temperature reads at 25c ish, so something must be wrong here...

Try uninstalling/reinstalling Core Duo Temp to see if you get more, lets say, realistic readings.

Unless, of course, you are in the arctic, in which case those temps are perfectly normal

[scattered]

Nevermind. I restarted and now it reads 65.

[frankthetank966]

I thought I was the only one with a cow in my computer.

[masugu]

So do we have some sort of consensus for a post firmware upgrade "cruising" temp?

Example. I am on Macnn - with only one Safari window open. Running my 20" Dell Widescreen, also core duo temp....and clocking in at 53 degrees Celcius.

[AppleOptionFour]

I am "cruising" at 54-56 at the moment. I think the fans are on but I have to be RIGHT next to the macbook to hear them.

Not bothersome at all.

[masugu]

Well, I am on battery power, only on one window of Macnn and cruising at 46 degrees C. Hope it stays at this level. I can hear fans if I put my ear to the Mac - but thats it. I LOVE it!

[Photo678]

safari, ichat, adium, and mail open on battery, in my bed book on my lap for the past hour temp is 53 deg. C

I used to have to use a small package of printer paper under the lappy like this...now, no need...slight warmth, but nothing more than that....sweeeeet

I knew they would get around to remedying this and had it not been for the dell fires, i dont know we would of seen this..but just happy to have a coolbook :-)

[soulboy]

Think I agree with most people, have had my macbook on for about an hour now and temp is staying around 40 to 43C before it was in the mid 50's. Only noticed mooing before when doing C2C and was getting temps of up to 80C+ will see if this comes down after this update. Now just have to get my yellow trackpad changed. Only changed from PC to Mac in June.........best move I ever made !!..

[jokell82]

The Dell fires were the lithium ion batteries exploding. It had nothing to do with fan control.

[andreas_g4]

My temp now idles at approx. 59 C - 62 C. It was about 10 degrees more before the update. Now only the top left gets warm. I'd still love to see sub 50 C readings, though…

[shadyg]

My Macbook (week 22) idled around 65-69, under load 78. After installing the update my idle is ~46, and under load (itunes, word, firefox, photoshop) it doesn't break 62 degrees. What a great fix, I can't hear the fan and never had any "mooing issues".

[masugu]

Great comments all around. I now feel that my temp drops are significant. I do believe I get lower temps - molike idling in the 45-50 range when on battery / web browsing away from my Monitor, but more like 50 - 60 when just web browsing with my monitor.

QUESTION
Anyone know where we may likely see some benchmarks / analysis of this recent update? Figure with all the hubub, anand tech or ???? might have something soon.

EDIT - Actually, here is one artcle, but no analysis or benchmarks yet - Apple Runs Fans Nonstop To Cool MacBooks - News by InformationWeek

[machead]

Everyone has been posting their processor temps, which while important, is not the most important thing from a usability point of view. Does anyone have any data about the temperature drops at at the bottom of the case? It's reasonable to assume that the temperature drops due to increased air circulation in the case may not be linear. (meaning a 10c drop in core temp may not translate to a 10c drop in case temperature)

As to the new fan behavior vs the old fan behavior.. I've noticed that people were saying that the fans now turn on at a lower temperature. Is this the case, or has the fan always been constantly running, albeit at a lower RPM. Doesn't seem logical to stop and start the fans constantly. Seems more logical to always have some airflow through the case as long as the processors are generating heat.

I know that, im just saying that with the heat coming from the books, i don't think apple wanted to be in a situation where people are calling and yelling and screaming that their computers are running warm, etc etc.

I really don't want a scenario like my 12" PB where a 17" external display caused Turbo Jet action. That was REAL annoying.


UPDATE: Post-Update - Its more 12" PowerBook like, but not as annoying when at idle. I am UnRARing some files, running at 56C and the fans are running at a much higher speed. Before the update the fans didn't come on until like 78C or so.

While typing this post, the UnRAR finished and now at 52C and the fans aren't on at all. Weird. Maybe it has something to do with proc load and current clock speed.

Anyone else?

Hi AppleOptionFour, I'm using the 20" screen and also the 23". It's fine. The old Powerbook used to blow loud all the time, but this is very smooth indeed. Only when I use a heavy rosetta-app like a game or Dreamweaver the temperature runs above 70 and the fans really kick in. At the moment there are about 10 apps open and some very heavy widgets, and I'm at 63ºC with hardly any noise from the fan. I think you'll be fine

There is no significant difference in case temp. 60c and 50c really isn't that big a difference to your lap after an hour, as both are a bit unbearable for long periods.

My old iBook felt just as hot on my lap though.

[Brien]

Mine runs cooler now.

[powerbook867]

Count me in w/ a much lower temp now after the update. Moo is gone and I am very happy this has been resolved...

I noticed that too, but figured it was just subtle PR.

[powerbook867]

lol, let's hope not...

[debohun]

However, I talked to an Apple representative yesterday, who tried to inform me that "Apple is moving away from making laptops" and only recommends its systems as "notebooks", i.e., not for use on laps. Presumable this is because the heat issue is still a considerable problem and that the ventalation engineering is hampered by use on "laps", i.e, ventalation engineering is still lacking. As long as Apple is obsessed with slim and sexy, rather than cool and functional, they are going to be sabotoging a market they should own. I don't know about you, but I could care less if my MacBook were a half inch thicker, it it meant I could use it in bed like I still do with my six-year-old Pismo.

No it means this is the firmware *update* v.1.0. The 1.0 refers to the update. The original firmware, was well umm, not an update, hence this is 1.0.

My MB is hooked up to a 20" ACD. The fan was never audible while idling before, and it isn't audible now after the update. Of course this is at room temperature with AC (68F/20C). I only hear the fan when I really crank up the load.

This is totally different from the 12" PBs, where just attaching an external ACD caused the fan to run constantly and well audible even when completely idle.

I haven't heard one single complaint about this update.

[telecaster887]

I seem to be having more problems since I installed the firmware. Before I had no problems with "mooing" or noise but now my fans are ALWAYS running and its very annoying in a quiet room. I'll turnon my macbook and just let it idle and it is completely silent for like 3 minutes. After that, the fans start getting louder and louder to the point where I can still hear them even with the TV on pretty loud.

My temperatures are also idling at around 63-69C which seems pretty high compared to everyone else. Is there something wrong with my fans? Should I bring it into the apple store?

[Simon]

What's your room temp?

[telecaster887]

Just a normal room temp, 70F?

[miss-haley]

i sent my blackmacbook in to get checked because of the excessive heat - and the fan was chuckin fits. hopefully the techs down here thought to run this update - i'm not holding my breath - seems they'll shave anyone and call 'em a mac tech in wellington. but after reading the multiple thermal gunk threads, i'm hopeful that i won't get serious heat probs from reading PDFs anymore. the techs said they replaced the logic board.... wheres the :crossedfingers: smiley when you need it!

oh and Hi there macNN forum.... noob introduction aside

[Simon]

So when you boot your MB in a 70F room and just let it sit there and idle, the CPU temp will approach 70C and the fan will run really loud? Did you check that there's no protective plastic wrap blocking the vents below the display?



What surface is your MB sitting on? A bed? Towel? Or a flat table?

Did you check to see if there are any background processes running that could be generating a big CPU load?

[telecaster887]

Alright so I checked my Activity Monitor and a Process called "isof" was using 99% on my CPU usage so I quit it and then deleted some widget that I think it was paired with? Anyways all the fans have stopped and it idles quiet and the temps are now around 50 which seems WAY more normal than 79C. Thanks for the help Simon.
