Mac Mini :: CD Random Fan-speed Bursts?
Dec 7, 2007
Every so often my Mac Mini 1.83 Core Duo w/Super Drive will experience a random increase in fan speed...the fan speed increases from 1500rpm to over 5000rpm for a couple minutes, and then will slowly return to normal.During these fan speed-bursts there is no increase/abnormal temperatures. CPU and Ambient temps could be at 40C. System load is also minimal (95% idle, eg).Haven't heard of this as a common problem, but is this fan behavior indicative of any type of problem?

There's been a large emphasis on the sequential read/write speeds of SSDs, but in many day-to-day usage patterns, the random read/write speeds are a better benchmark of performance. I'd like to make a chart summarizing all the different SSDs out there and available. But I need your help. Can those of you with SSDs run a benchmark and report the numbers here so that I can compile everything? Here are the steps:
1. Download Xbench 1.3 at [URL].
2. Open the program and run the "Disk Test" for your SSD drive.
3. Note the numbers under the Random test, for all four parameters of small and large writes and reads.
4. Repeat the test a second time to make sure that the numbers do not change. Accept the second test if the values are <10% different from the first test.
5. Screen capture the window by holding down command and shift and 4 and the spacebar. Click on the result window and that will save as a png file on the desktop; the default is Picture 1.png.
6. Report the values here with by attaching the screenshot of the result window. This will give us other needed information like computer and SSD model.
I realize that there are weaknesses to this survey. Xbench is only one benchmark. SSD speeds will vary based on usage. Etc. In the end, however, the variability should be sufficiently small that I think we'll be able to compare different SSDs well.
I'm going to get us started by posting my results with an Intel X-25M on a previous generation MacBook Pro. Ironically, my result will probably get thrown out because the SATA 1.5 GB interface actually limits the SSD read speed...

I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.

After resetting my Mac mini with the PMU reset it
- runs its fan on full speed
- the front (power) LED does not show anything
- SMC fan control shows "0�C" / "000rpm"
Any way how to fix that? I did a PRAM and PMU reset again, but no go.

mine is always around 1800 rpm regardless of internal temps. i spiked both cores of the cpu to 100% for 5 minutes (cputest), and the cpu temp got up to 164F (73C) from an idle temp of 100F (38C), but the fan was still 1800 rpm. i played a bunch of 1080p trailers simultaneously to give the gpu and hdd a workout while transferring a few gigabytes via wifi. fan still stayed around 1800 rpm.
during the 2 hours while the migration assistant was doing its thing, the top of the mac mini got fairly hot. not scorching hot, but noticeably warmer than idle, while the fan was still quiet as usual. i could feel really hot air coming out of the rear vent, but the fan wasn't blowing harder than usual. i'm assuming it was running at 1800 rpm even as the hdd was generating some massive heat. this is very troubling to me. has anyone seen the fan increase in speed as temps rise in the latest mac mini (macmini4,1)?

I have a 2011 mid range mac mini and love the machine, however I have noticed a few things. First off, it seems to be a bit on the slow side when multitasking. I have the standard 4 gigs of ram installed, but running programs like MS Word and Safari at the same time, the machine seems to struggle a bit. Also I have noticed when doing a lot of file transfers via USB, the fan will kick up to high gear for a few minutes and then drop down. Is there something wrong or is this normal? I'm doing a time machine backup of 120Gigs, have safari open and activity monitor open. Activity monitor states 1.16Gigs free, 792MB wired, 961.4MB active, 1.12GB inactive, 2.84GB used. VM size is 150GB, page ins are 962, outs are 380kb, swap used is 10.5MB. Right now the fan seems to have slowed to a mid range mode of some sort and is not in high gear.

I just bought my first Mac for use in my personal photo studio, a refurbed 2011 Mac Mini i5 2.5ghz. As I was setting up external drives and putting the mini through its paces, I ran a disk benchmark (BlackMagic Disk Speed Test) and got some pretty poor scores.
My mini's internal drive hits roughly 40MB/s for both sequential read and sequential write. Am I correct in thinking that this is poor performance even for a 5400 rpm drive? The drive is mostly full; there are 50GB free. Would you recommend that I address this with Applecare?

I know that the server version has a 7200 rpm HD, but what about the regular version? Also, is the 500GB upgrade HD on the vanilla model a 7200 version?

I realize the L2 cache is half the size and the CPU is a bit slower, but if each machine had 4 gigs of ram, would they be more or less comparable in performance (aside from the GPU)?
Also, how does the Mini fare with Vista in BootCamp / Parallels?

Sorry for the title but I couldn't think of anything better. Hopefully I'll be able to explain my problem. I have a MPR 2.53 ghz, 4 gig ram, I'm using Safari 4.04. I am using the WIFI at a guesthouse in Thailand (but I had the same issue in China, Vietnam ...). I ran a speed test and it said download 7mb/sec and upload about 1mb/sec. I have an "app" that says bandwidth in 1.3kb/sec out 1.0kbs. I thought maybe it was Safari so I downloaded and installed Firefox. firefox gives me similar speeds. When I downloaded Firefox though I had a download speed of over 1mb/sec. But as soon as it finished downloading the speed went back to around 1kb/sec. I have rebooted my MBP many times. I did some Google searches but didn't find anything helpful.

I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

I have a WDS local network at my house. I use a Airport Extreme in my main part of the house and a Airport Express for my back part of the house i.e. the backyard. Now every two weeks or so my internet speed through my Airport Express slows down about half the speed but when I am connected trough the Airport Extreme my speed is normal. I know this because I test my connection very often. Now when I want the Airport Express to get back up to speed I have to unplug, and plug it back in. Then after awhile it starts to slow down again in a time period of two weeks or so.

Have an Extreme base stations and express repeater connected to my DSL services. On my primary iMac connected via ethernet I get 5.25MBps speed. The speed on this computer is always constant. On the remote MacPro I get anywhere from 1.5MBps to 5MPps speed within a half hour of testing.

I'm using Data Rescue III on a USB powered hard drive with and it's taking a very long time with my iMac G5... It says 42,291 hours remaining (about 5 years) If I did it on my Mac Pro would it go faster, or is the recovery speed based on the hard drive speed?

i have a 1.5 Mbps AT&T DSL connection, and multiple speed tests show a download speed of 1.2 Mbps (and 200 Kbps upload). when i download files, such as software updates from Apple, various podcasts, and even Silverlight from Microshaft, the speed is always between 140 - 160 Kbps. i contacted AT&T, and the rep said it was because of buffering by the servers i was receiving the files from. is this a reasonable explanation? is this an accurate use of the term "buffering"?

I generally get about 700kbs download speed, which is what my ISP (Sky uk) tells me I SHOULD have, but they also tell me that my router upload speed should be similar and it's not anywhere close to it.

Does it hurt the computer... If the computer is doing something (watching flash, playing a game) that turns on the fan full speed;Does this hurt the computer? There are a few games I like to play and they turn on the fan at full speed (computer gets hot too, on the bottom.)

I've got a real odd problem with safari 4. For some reason it is cutting my download speeds in about 1/2 from my server and many other places.
If I restart safari I will be able to download close to my 18 Mbps for a little bit but then it will just start to slow down and after about 30 minutes it will be down to about 6 - 8 Mbps.

I have an Early 2009 Mac Mini with Mini DVI and Mini DisplayPort. And I have two 1080p HDTVs. The Mac Mini is capable of dual display, and I've gotten it to work before, so the issue is not the TV or Mac. And I have tried both Mirroring and No Mirroring.
I got a Mini DisplayPort to HDMI Adapter (#5311) and a Mini-DVI to HDMI Adapter (#4852) both from MonoPrice. And for some reason I can't get the Mac Mini to dual display, it's only one or the other.
Before I had a Mini Displayport Male and USB Male AUDIO to HDMI Female Converting Adapter (#5969) and I got video on both HDTVs, but not audio at the same time b/c one was USB and one was TOSLINK.
I'm not sure why I can't get video on both monitors. Any help?

I need to connect my 09' Mac Mini to my Yamaha RX-V2700 receiver which outputs to my Sony XBR HDTV. I know the mini has both mini-dvi to dvi and mini-dp to dvi or hdmi available via adapters. I was thinking to go with option 1 however I was wondering what is your opinions? Is mini-display port better over mini-dvi or are they the same? Audio will be carried over optical toslink.
Option 1:
Using mini-dvi adapter to dvi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
Option 2:
Using mini-dp adapter to dvi or hdmi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.

I keep hearing this random sound while using my new MBP. Sounds like a guitar chord being strummed but it's very, very brief. It's happened while in Firefox, iMovie, Findit, etc. What is it?

What would cause random restart? Maybe one in 15 times, when I lock my display, I will find that in the morning, my computer had restarted without my doing. Irritating as I rely on it for an alarm clock and as I have to log in, the alarm doesn't restart in the event this happens (almost overslept an exam today because of this). I am on a late 09 mb with 10.6.5 running.

I have a 2008 iMac running OSX 10.6.5, 2.66Ghz Intel, 2 gig ram. I'm getting random blue screen crashes at least weekly. I don't have any hardware connected except an iomega external hd for Time Machine (and of course a keyboard and mouse). I'm never doing anything exceptional when it crashes. Usually just internet browsing (Chrome) or word processing (NeoOffice). The screen just suddenly goes gray/blue and I have to force it to shut down with the power switch.
I upgraded to Snow Leopard at the same time I installed Windows 7 (Boot Camp) and purchased the external hd. The problems started around that time. I have since wiped the disk and reinstalled both OSs, but am still facing the same problem.
