MacBook Pro :: Fans Never Spin Up While Under Stress
Dec 2, 2010I was noticing a lot of slow-down while playing computer games on my MBP. My computer far exceeds the minimum requirements for everything, so I reckoned it must have been something other than a slow processor (2.53 GHz Core 2 Duo), low ram (4 GB) or a completely inadequate graphics card (Nvidia 9400M). The games range from 'Day of Defeat: Source' to the 8 year-old 'Return to Castle Wolfenstein'. After a bit of research, I came to realise that my exhaust fan is never speeding up past 2005 RPM no matter WHAT the load on the CPU is. To test this, I downloaded smcFanControl and ran CPUTest. As the CPU went from 50*C to 95*C, there was hardly any change in the fan's speed. The variation went between 1995 and 2005 RPM.
In order to keep the computer relatively cool when playing games or doing anything that is CPU-heavy, I have to manually increase the fan's RPM in smcFanControl. I find that setting the fans to the maximum, 6000 RPM, keeps the computer cool enough to process these games. This program works wonders and I've not had any slow-down in games as a result. However, I am worried that there might be something wrong with my Mac. Why does it not automatically increase fan speed when reaching higher temperatures? I've even reset my SMC (SHIFT-CONTROL-OPTION-Power) on start-up just to be sure I've tried everything. Any suggestions as to why my fan seems stuck at 2000 RPM?

MacBook Pro :: Magsafe Put Stress On On Cord At Connector
Oct 12, 2010I really like the new design of the Magsafe power cord connector. But both designs still put stress on the cord at the connector, if your Macbook is moved. I hope Apple gives the Magsafe a swivel, so the cord can move more freely as the laptop is moved. Am I the only one thinking this would be a good idea?

Jul 20, 2010I've now seen 2 machines have a logic board failure from letting the battery run dry (which shuts the computer down). I suspect the voltage regulator based on what I've seen and reading up on what the board level repair guys are finding. My question is does letting the battery run out stress the voltage regulator and is this situation to be avoided at all cost?

Mac Mini :: Music Production - Deal With Heat Under Stress?
Sep 11, 2010I'm eyeing the mini right now because os x >>> windows for music (inherent midi drivers instead of 3rd party, stability, etc etc).amittedly I currently run a hackintosh on a previously windows pc. It is stable with the exception of gfx crashes every few hours and its inability to use the gfx card to its full extent. This gets to me though and is kind of a bitch. So I'm thinking about getting a mini when I have the money for one. I would get the standard with the 4gb ram option. How well does it deal with heat under stress? and is the HDD 7200 rpm for the non server edition?(edit: roarrrr just read that its 5400, so lame)

Sep 27, 2009I've been playing a bit of Poker using the PKR application (It's a cider port from what I've seen). I'm finding that on my iMac (and not my MacBook Pro), after playing for a while the graphics go a little bit screwy then it freezes the entire system. To try and diagnose the problem I want to see if it's the app or the GPU which is causing the problem. Does anyone know how I can stress test the GPU?
What's odd is that even though the app seems to be very CPU and GPU heavy, I don't really notice any fan noise from the iMac. I'm just concerned that it may be overheating.
