View Full Version : MSTS Causes Chassis Fan To Run Fast

It seems that every time I run MSTS, the chassis fan will run at full speed for about a minute or two.
I have PC wizard installed, and it says my GPU temperature is 69C after running TS for about an hour.
Any ideas?
Here's my setup:
P4 3.0 GHZ
NVIDIA 8500GT - Factory Settings
2.5 GB RAM
200 GB SATA HDD
ANTEC 350 Watt PSU
Thanx

Nothing to worry about, Bob !
But having a look at the inside of your computer and checking all fans, case, graphics card and the CPU cooler for build up of dust now and then is recommended to make sure that they do not suffer damage from overheating.
If there is excessive dust then use a vacuum cleaner with a soft brush attachment to get rid of it !

Bob, you might want to beef up that power supply if you can... 700+ watts seems to be the norm these days with the newer cards.

Yes. MSTS runs the CPU at 100% (at 50% with dualcore) Running a lot of instructions does cause the CPU to heat up and this is perfectly normal.
The fan speeds up in response to a CPU internal temperature sensor.
The logic tries to keep the CPU temperature as consyant as possible...this minimizes thermal stress on the chip.

As others just said, and as they say in French, Sans Blague! No Kidding!
Yes, MSTS does run your processor hard. If it is a problem, a bigger fan might be a solution more than the power supply. Be sure you dust things out before you spend the money though. :)

Paul,
Yes, as I said ANY program that causes CPU usage percentage to go up produces heat as a by product of switching millions of transistors to change state. A bigger fan would just be sucking more dirt in. Annual cleaning is the answer and it costs nothing! ...except time and canned air.
You can check if it's a program that does this easily. Look at the Task Manager inviked by a Ctrl+Alt+Del press. Look at processes and click on the CPU column header to sort the list by CPU usage.
Now with nothing running in the foreground and background note the CPU usage. With nothing running on my XP machine it's about 2-5%. The fan should be running at aslow speed assuming your system is equipped with a variable speed CPU fan. If you have a variable speed fan and it's running fast at low CPU usage you can almost bet that the CPU heat sink (cooler) is clogged with dirt. This is how I plan my desktop cleaning schedule;
If I can hear the fan running fast after a clean shutdown and boot AND nothing is running (the 2-5% usage figure) then it's time to bite the bullet, crawl behind my desk, disconnect the box and take it outdoors for a blow job. :D Remove both side covers to do this (usually 4 phillips head screws at the rear)......outdoors because the dust flies everywhere...stay upwind too. :p
Use a vacuum cleaner on blow if you can. Canned air is okay too but dont blow on main board components too close with the canned air. Why? Good question Watson. Blow the canned air on your wrist as you would blow away dust on the main board. Cold huh? How about minus 30 to 50 degrees F cold! :eek:
That kind of thermal shock can fracture interchip printed circuts, break internal chip connections and other havoc. The blowing from a vacuum cleaner is better because the exaust air from a vacuum is comfortably warm.
A hair dryer set to cold is another alternative to cleaning out the crud.
I know someone that uses a garden leaf blower to get the job done.
Myself, I have an air compressor in my garage and use the blow nozzel to do the cleaning. This also has it's dangers; too much pressure can damage delicate components.
An example; If you direct such a nozzel at the cooling FAN, the fan will spin at a VERY high speed. This WILL damage the fan bearings or cause the fan itself to disintergrate. Believe me, you can get that little sucker over 50,000 rpm! You don't want to do this so hold onto the fan to prevent it from a runaway spin.
I find that once a year cleaning is pretty much a good thing even here in the dusty Mohave Desert. :cool:
Remember to be careful with the canned air. A soft brush is a good accessory for this.

Good advice, Vince.
It's trickier to clean a laptop than a tower, though.
Myself, I've found canned air works best, but needs to used with care. Remove (with appropriate precautions) the battery and removable hard drive, plug-in cards etc. from their compartments. Put a Q-tip (or if that doesn't work, a thick and sturdy toothpick) to stop those tiny fan blades, and then use the air.
