Laptop cooling frame rates
SH4 runs well on my laptop. However after sometime it gets extremely hot. I read in other forums that gamers were setting their frame-rates to fixed rather then unlimited and found the game would run cooler. Last I checked my frame rate was around 60 FPS.
Is it possible to set the frame rate in SH4? |

If I understand correctly checking vertical sync in the graphics options will limit your frame rate to your screen's refresh rate. That's the only way I know.
My screen refreshes at either 40hz or 60hz and I use 60. You may not notice any difference in heat produced if you were already running at almost exactly your refresh rate but this will at least keep it from trying to do 130fps when nothing is happening. |

If you are experiencing heat problems, I suggest you solve it at the source. And not limit the frame rate. It is very likely that the fan inside the laptop has a dust layer on it's blades. And even more likely, after a build up over the course of a year or so, a thick felt layer develops over the cooling ribs of the heat pipe. This prevents the air from flowing through, so no where for the heat to go to. The CPU and GPU will probably throttle down it's performance to prevent overheating. So there is enough to be gained here.
I understand if you do not dare to open up your laptop case. In some brands the fan can be hidden deeply inside, requiring substantial disassembly. But the fan case might also be fairly easy to open up. If you do not dare to do it yourself, consider letting it be done by your local pc repair shop. I consider this a required maintenance task, to be done regularly or at least annually. Depending on how dusty your working or playing environment is. |

Pisces - I have been thinking of doing just that. This weekend time for a cleaning.
SilentPrey - thanks for answering. That's what I wanted to know. |

I've had my laptop overheat and shut down a few times so I sit it on top of a trivet - a couple of cm between table and machine makes a big difference - although Pisces advice is better for the machine, it won't hurt to improve airflow no matter what state you're cooling system is in

My wife has a humongously powerful vacuum cleaner - says "12 amps" although that's probably just marketing jive. Anyway, I put the suction hose flat against the fan grille, and let 'er suck for a minute or so. Then I do the same with the intake grilles. A hand cleaning would probably be more effective, but this seems to help, and it's quick and easy. I do this about once a month, or whenever I hear the fan running at high rpm more than it normally does. The vacuuming will return the fan to normal duty cycles, so I conclude that it is effective. |

But worse is that with sucking from the outside, you suck the felt between the cooling ribs. You might even make it clogg up further with a heavy duty vacuum cleaner. The spaces are usually less than a milimeter wide. Once it is in there, you won't get it out easily. Really, get yourself some screwdrivers with tiny tips, and go inside to get the felt out. |

When you put the mouth of the vacuum to the opening, the cooling fan will exceed max RPM and could damage its self. Quote:
The way I clean the heatsinks of my laptop: 1) large piece of paper (a4 size is fine) 2) draw the laptop on it and mark where screws go. (don't forget the ones by the harddrive and DVD player. You wouldn’t want to place the wrong screw in the wrong hole, believe me). 3) take a straw (a Mc Donalds sized straw is perfect for the job). 4) fold and cut the straw in a way you get about a 3cm sharp elongated arrow tip (don't cut it in one go but make small incisions, you don't want a smooth surface). 5) use the newly cut end of the straw and start moving it back and forth going up ever so slightly every time between the heatsinks cooling ribs. 6) take the rubber hand pump and place the opening in front of the just cleaned rib and press the pump a few times. 7) place the straw inside the same rib again redo step 5 together with step 6 this time. 8) do steps 5, 6 and 7 with every cooling rib. 9) take the cotton swabs and gently clean the fan blades and the insides of the fan casing. 10) take the rubber hand pump and blow between the fan blades while keeping the blades from moving. 11) when all of this is done use the rubber hand pump and go over every part of the laptop in order to remove as much dust as you can. 12) close it up (in reverse order to opening it) and you ready to go. If you follow these steps, I guaranty the temp will be between 30c and 35c (running idle) and will sound like new. PS_ You do this at your own risk, I will not take any responsibility if you trash your hardware in anyway. |

By checking vertical sync I was able to get the heat down from 87 C to 75 C. Still very hot but enough to keep the laptop from shutting down during the game. SH4 runs well, no performance hit.
When at a hotel I also use a trivet or book to elevate off flat wood. However I did notice my laptop was running hot just running windows. So yesterday I took the great advice here and gently blew out any dust on fan and ventilation. It didn't look like that much dust but WOW what a difference. Last night I ran SH4 for a couple hours and only got to 48 C. As I type this the bottom of my laptop is cool to the touch. Thanks for all the great advice. |

I could luckily resolve my overheating problems with a vacuum carefully applied from the outside of my laptop (Dell XPS L702x). Procedure may differ from laptop to laptop.
Thx Ron |
