Why does it turn my laptop hot

[AppleQueso]

My girlfriend's computer used to idle at 95C, but I think that was just the temp sensor going haywire and not the actual temp it was running at.

I am getting heat around the 75C .

Ouch. I'm not sure the components are taking that without deteriorating.

As others have said, keep those temperatures away from your body, you can even get skin burns.

Have you ever cleaned your laptop fans? It may be a good idea to try that. Get a can of compressed air, have a look at some youtube videos on how to do it.

all of you guys are scaring me, the norm tempreture is 65c , thats cool for me sunce I got this laptop. When I do video converting its normal to reach 82-5c. Ive seen 92c once.

at 50 I consider it cold, but yeah, mostly its 70-75 doing anything task intensive like games or even watching flash videos.

I thoguht this was the normal tempreture for PCs

[sabrage]

What are you using to gauge these temperatures?

[AppleQueso]

I'd get maybe 2 or 3 different software temp monitors and see if any of them show wildly different temps.

When you emulate a game through Dosbox you need like 8 times more power than it used to need. Hence, emulating a pentium game is quite a feat!

DosBox is not like a traditional emulator because the instruction set is the same. It only needs to remap the DOS/Windows BIOS/API calls. So the processing requirement will be less than a traditional emulator (e.g, Nintendo NES emulator on an x86 processor).

i am dual booting between mac and windows , i get same tempreture reading although the Windows seem cooler a bit. I use iStat widget on mac and coreTemp for Windows

I womder if it is dangerous to rin games on my laptop since I dont plan on changing my computer for at least couple of years until some new technological jump comes along as my laptop seems just as fast and capable as the brand new laptops, even though its 4 years old, except for running recent games of course....doesnt help being mac hardware.

This is funny but seems my iPad runs HD games in cooler conditions :p

75C for CPU temperature under load isn't abnormal, depending on cooler and such. Intel CPUs usually shut down at/near 100C.

In a desktop, it's no big deal (or if it is, you can get a better cooler). In a laptop, it means warm/hot surfaces and little fans spinning like dental drills.

The people claiming those temps are hot must not be real familiar with laptops. Those temps are perfectly normal (I owned two MBPs, one with almost the exact same specs then later one with the GeForce 320m). I recall seeing 81c on more than one occasion, and almost all laptops I've used push those temps as well. You need not worry unless you're pressing 85-90c.

To those wondering, iStat is an extremely reliable stat monitor for Mac as well.

Apple has this issue of compromising performance for aesthetics. The hinge-fan has never worked well and never will. I remember my 12" PowerBook G4 that loved to hit 91c when watching videos etc.

But yeah, keep that sucker off your lap, those temps aren't good for the man parts, especially since Apple's laptops are made of aluminum.

DosBox is not like a traditional emulator because the instruction set is the same. It only needs to remap the DOS/Windows BIOS/API calls. So the processing requirement will be less than a traditional emulator (e.g, Nintendo NES emulator on an x86 processor).

As far as I know, Dosbox fully emulates the CPU, it does't remap calls, which is why it works on so many devices that have nothing in common with Windows or x86 architecture.

On power, it really takes more power than any other emulator I have used. It's easier to emulate Amiga and PSX games than using Dosbox, I will probably use PSX ports if I get a Caanoo because the console simply can't emulate the original games without crashing or slowing everything down to a crawl.
