Fan speed and CPU temp viewing Flash video in Firefox vs. Safari ?

My MacBook (two months old) running the latest Safari version (3.1) seems to be working unbelievably hard when viewing a flash video. The temps seem to cycle between the high 60s and mid 70s, and the fan blows at max speed constantly. On the other hand, when viewing the same flash videos using Firefox (2.0.0.12), there is only a slight boost in temp (high 50s to low 60s) and the fan speed hardly increases at all.
Has anyone else noticed this?
Why would the flash player on one browser be so much more efficient than another (Safari seems to labor, while Firebox breezes along)?

Thanks!
Well I guess the code in the Safari browser just wasn't well written. This is true even of the later version of Safari. It does work much better in FireFox, with no crazy heat-up or fan action.
I've pretty much given up on Safari now on everything by my iPhone and iPt, and only because I have no other choice.

Fan speed and CPU temp

Hi There,
I have MBA 13'' Mid 2011.
I'm little bit concerened about Temp of my CPU which is 96°C, and Fan speed is around 6500rpm.
I can hear my fan all the time.
It was not like this always and i'm kind of sure that something is causing this.
I worked before with lots of apps open (itunes, photoshop, text editor, chrom, mail, parallels..) and fan and temp was not this high.
Is there way to find out what is causing this high usage?
Thanks in advanced

First execute a SMC reset:
http://support.apple.com/kb/HT3964
If no change, install istat menus.
http://bjango.com/mac/istatmenus/
Open Activity Monitor to ALL PROCESSES and CPU. Make certain that CPU displays values from high to low.
Post images of both istat menus and Activity Monitor whe the MBA has heated up.
Ciao.

Tweak the balance between fan speed and CPU temperature / Dell M6400?

Hi all,
I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that

When I start the laptop, its CPU fan stays at its minimal speed only for 1 or 2 minutes, then increases its rotation speed to a second level. It reaches it maximal speed only under heavy load, when the CPU reaches >80-95°C. I would rather let the CPU run a bit hotter before the fan starts to blow: let's say the fan could enter its intermediary speed between 70°C and 85°C instead of 55-80°C, and blow at is its maximum speed beyond that.
I checked the Fan Speed Control wiki page, but lm-sensors is not able to show me the status of the fans. Any idea ?
Aurel.
PS: the temperature of the GPU is not reported by sensors, and nvidia-settings reports around 60°C. Its dedicated fan is very quiet.

Hi aurelieng,
I'm in the same situation from at least 1 month ( INTEL CORE 2 EXTREME X9100, 3.06GHz with 8GB ram, one solid state disk 128 GB, and one sata disk 500GB)
My dell M6400 has dual boot: ubuntu and windows7. The fan works a lot and continuosly in both environment and this is the reason because I have doubt that the origin of the problem is in hardware problem?

Unable to view flash videos in Firefox. Please help.

Hi there,
I've tried all the troubleshooting from Firefox's troubleshooting guide to no avail.
I'm unable to view videos that require flash.
I can watch YouTube, but I have to enable flash first.
This has never happened before, but now it won't go away.
System: Windows 7 (64-bit)
Adobe Flash version: 16.0.0.287
Browser: Firefox 35
An example of videos that I used to be able to watch were from the Arrow and, ironically, The Flash TV shows.
Now this is the error I receive:
CWTV requires Flash Player 10.2.0 or higher.
Arrow Video - The Climb | Watch Online Free
Please help!
Best regards,
JM.

Problem viewing flash video on Firefox

just came across a very odd problem happening with Firefox only.
The video loads first time and plays, however if you click the next time it comes up saying cannot access/access denied, couldn't replicate in any other browser.
Basically it works fine first time after clearing the cache in FF.
it's odd, would need a resolution immediately.
- you should get a video link on the home itself.
*in case u cannot access it please try out in sometime since we update it sometime.
Please HELP!

What exactly means "will not allow"?

Is there a way to view Flash videos on my iMac without downloading Adobe Flash Player? I'm concerned about performance and security with Flash Player.

Is there a way to view Flash videos on my iMac without downloading Adobe Flash Player? I'm concerned about performance and security with Adobe Flash Player.

If the video is only available in a format that requires Flash player : then no.
However, a great many can also be viewed in an HTML5 version, in which case http://hoyois.github.io/safariextensions/clicktoplugin/ or similar can be set up so that Flash never runs unless you specifically choose it to.

How come when I view flash videos my videos stop, but the audio plays and I see rainbow colored lines up and down the video.

How come when I view flash videos my videos stop, but the audio plays and I see rainbow colored lines up and down the video. I attached a image below.

ATR, just to make sure you understand me, all my video clips in my folders appear as the first frame of the video clip when I view my folders as (small, medium, large)icons instead of lists, when saved as .avi files but when saved as .mp4 files, those icons display as a graphic icon of filmstrip with a musical note on it. I do have various other methods to open with (quick time, windows media, winamp or real player) but prefer real player because I like it's quick and easy trimmer that comes along with it, since so many of my videos are just pet antics where you need to clip off the boring beginning and ends of the video.
I did go on a few of the icons and right clicked, Open With, and tried quick time and also Windows Media and it did nothing as far as how the file was saved for display, and they opened the same no matter which player I used...the actual video opens and plays right at it's first frame... but it's the way it is visually displayed in STORAGE that bugs me because it isn't immediately apparent to me what it is a video of (weddings, outside the house, pet antics)... it makes me have to actually title things and read titles where before I let it just be dates because I had the visual of that first frame as a reference. Obviously, this is a problem for unedited videos only, as anything I actually work with, I do give a title along with the date of the video.
I also just realized this seems to be the way ALL videos that are wrapped in .mp4 are displayed, as my bloggie camera's videos appear the same way. Now I know why! My other videos display as .avi's so I see the frame. Puzzle solved. Guess I'll just have to learn to live with it, as it seems to be how things display with the various formats.
Now I need to watch some tutorials to learn how this Premiere program works! It's all new to me, since this is the first time I've been able load any of my videos onto it. I haven't even been able to figure out how to trim on it yet!

What are you using for Fan speed AND temp monitor?

Thanks to Bosskiller, my rig seems to be running a bit stabler now! Knock on wood. Is there any program other than MSI's core center that monitor fan speed AND temp? I used to use MBM but it's no longer being supported and CoreCenter doesn't seem all that popular here?

Quote from: BOSSKILLER on 25-September-08, 00:42:40
http://www.cpuid.com/hwmonitor.php
http://www.alcpu.com/CoreTemp/
Actually how accurate is the temp reading on HWMonitor for your MSI board? One thing I noticed is that w/ Coretemeter the temp reading was around 48-50c on Rig#1 and almost 58-60c on Rig#2 (That's my HTPC w/ EXTREMELY tight spacings so still work in progress as far as cooling's concern!) but using HWMonitor I got 31c CONSISTENTLY on both rigs! I'll love to think that I'm indeed running this cool but feeling the exhaust air, I think this 31c reading is not real...

Fan Speeds, and Mirror Raid with New Internal Hard Drive

Regards,
I recently installed and formatted a new hard drive in my PowerMac dual 2.3 ghz computer and I have a few questions.
1. Now that there are two hard drives do I need to do anything to ensure that the fan on my computer can keep them cool? I think the fans I have in the hard drive bay is enough, but I do not know if they will automatically set themselves to run properly. I can monitor the fan speeds and temp from iStat pro, but do not remember what level the temperature was before installing the new one.
2. Given that my new drive is a SeaDisc hard drive and the older one is a Western Digital, will this cause any problems in creating a mirrored RAID. I believe that both are 7200rpm drives, and my second hard drive is a little larger (I will just have unused space after making the RAID). I am concerned with the fact that these two drives are from two different manufactures. Will this cause problems or drastically slow down the reading and writing of data? Has anyone else experienced problems in making a mirrored RAID from two hard drives that are not exact matches, and even come from different manufacturers?
Any advice will help.
Thanks
earpshmael

Hi earpshmael;
Generally when creating RAID arrays the more similar the drive the less problems you tend to have.
The real question is exactly why do you want or need RAID?
I think so many people seem to think that RAID will solve all of their problem. I hate to tell you the bad news but it will not.
Generally there are to varieties of RAID available using the software RAID built into OS X which are 0 and 1. RAID 0 or stripling is generally for moving large file rapidly for applications like HD video. It usually doesn't help the OS. RAID 1 or mirroring is for protection from drive failure. It is not a valid backup solution.

IMac (early 2009), 3.06 GHz, ATI 4850 - fan speed and temperature questions

Well, so I downloaded and installed Temperature Monitor and iMac Fan Control - mainly for observational purposes and not for toying around with the fan speeds and I've got some questions. Mind you, I haven't tampered at all with the fan speed settings, just installed Fan Control. Here are my readings (while browsing the internet with Safari and doing a chat via iChat):
Fan Speeds:
CPU fan (desired) 1300 RPM / (current) 1530 RPM
HD fan (desired) 2100 RPM / (current) 2099 RPM
DVD fan (desired) 1300 / 1298 RPM
Temperatures:
CPU Heatsink: 92°F
Internal HD: 108°F
Internal DVD: 95°F
GPU Heatsink: 107°F
Are these, under the circumstances, normal readings?
Thanks in advance for your replies.

Your welcome and no problem. I would say only the Apple engineers can tell you why the fans are set to those speeds however my best guess is the obvious they found those speeds the closest to keeping the temps at an optimum operating temperature. I found when I'm doing graphics intensive work my machine heats up but quickly cools down when I'm done.

[Solved] lm-sensors fan speeds and voltage.

I suspect this is something that I am doing wrong (or is it a kernel issue??) as I have the same problem on a similar machine running Ubuntu 10.04.
Any ideas appreciated.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
* https://support.mozilla.com/kb/Safe+Mode
* [[Troubleshooting extensions and themes]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox 4 you can use one of these to start in <u>[[Safe mode]]</u>:
* Help > Restart with Add-ons Disabled
* Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

Mouse wheel scroll fails after viewing flash video

It appears that viewing flash videos on hulu or youtube "breaks" the mouse scroll wheel function. The rest of the mouse buttons remain unaffected - the forward/back buttons work fine, as does the mouse-wheel-click scroll and the mousewheel-left/right scroll.
The scroll function remains completely unaffected in other applications.
Closing the window or tab that had the "offending" site in it sometimes seems to return things to normal, but not always.
I use flashblock and noscript, but disabling either or both of these vital plugins seems to have no effect.
Just disabled both plugins again to test once more, loaded a vid on hulu, and stopped it; all seemed fine, but after hitting "back" to go back to my queue list there, the scroll stopped working.

focus owner was null
requestFocusInWindow();
after the move did the trick

848P In CoreCenter - NB Fan Speed - But no Temp?

Hi,
In CoreCenter i can see CPU Temp, Fan Speed etc, but i only get NB Fan Speed but NB Temp is shown as N/A ?
Any ideas?

Hi Matd,
This is due to limits on the Mainboard.
You not be able to see +12V either.......
As the 848P chipset is a CUTDOWN version of 865, you will lose quite a slice of important info!!!
