Can someone clear this up for me? I've tried google for about an hour now and came up empty.

I need to show someone that running a PC game and winamp is not gonna destroy their CPU by overheating it.

Or that downloading 3 files at the same time with IE is not gonna overheat their processor...

I know this sounds dumb... But I need an article or something, or they won't believe me. :mad:

Thanks.

Does their computer have a temperature monitor that you can show them?

every PC i own and have ever owned has run Folding@Home, 24/7, never ever EVER being off.
100% CPU usage 100% of the time. None ever "overheated" nor have any CPUs died. I firmly believe but cannot prove that shutting PCs on and off does more harm

I always leave my laptop on, sometimes i'll put it on standby when I know I wont use it for a few hours

I have NEVER heard of such a thing...jsut because you are running those programs at the same time isnt going to overheat the computer....it will lag it but not overheat it. I actually use winamp while playing quake..and no problems. I leave my computer on for weeks at a time and I dont have overheating problems... If he still dosent believe it than tell him to guy buy a processor fan for more cool air.

It's impossible.

Unless they're running a Toshiba Satellite. But that's a design flaw. There's a class action on it.

They sell heat sink devices for laptops that run hot. Somehow it disperses the heat from underneath. Some have extra fans built in.

I've been meaning to get one, but instead I prop the laptop up when it's on the desk so that air can circulate underneath.

I only have a desktop system, and unortunately the tower sits in a small conined area, so it builds heat up excessively, especially if I forget and leave somethign on topof it, I might try Elvis' method of propping it up.

Don't listen to this guy, he doesn't know squat about PCs. Besides having your computer Fold your clothes at home doesn't really test how much it can heat up the processor, unless you get them fresh from the dryer, then maybe.

If you have a functioning heatsink / fan on the CPU it would be damn near impossible to destroy it even running a program(s) that tasks the CPU fully at 100% like Folding or GIMPS. Most "normal" programs don't task the CPU 100% all of the time, some distributed computing programs can be an exception to this. Even if it gets too warm for the level of cooling inside of the box, it will usually either just lock up or bluescreen/reset on you, but not really harm the processor. Now if the CPU fan quits and you run it at 100% utilization for several days, err maybe ? But I've done this and still the box was simply locked and the CPU was fine. Because once it does lock up you're no longer actually running the threads through the processor and it will begin to cool from full utilization.

Without divulging too many old secrets, CIWS used to review computer hardware for a world-famous computer hardware website....one could honestly say he knows his stuff :worship:

I neglected to mention that at some customer sites I have systems that have run over seven years uninterrupted. I keep telling them the systems are obsolete and due to crash, but they wait for a disaster.

The CPU is probably only hitting 50% capacity during peak hours. Most of what we do is not heavy work for these units. Still, they're running. The fans do their jobs effectively.

It's extremely rare when any unit sustains 100% CPU capacity for more than a few minutes at a time.

I've been using, building, repairing, modding, and cussin' at computers since 1976. I agree with CIWS - most modern (Post 2000) computers have more than adequate heat sink / cooling to handle pretty much anything you'd throw at them in a normal environment. So long as the ventilation in the case is not blocked, and the insides are not coated with decades of gunk, fuzz, toe jam, cat hair and other unsavory debris, the CPU will be fine. I have almost daily contact with old 386s and early Pentiums that have been running 24x7 for years. But there is a difference between "just sitting there" and running flat out, to be sure.

Jon, your friend may be un-swerveable. In that case, do what I do. Get a new friend. :)

In re: Start/Stop vs Leaving On 24x7 : In the old days, the wisdom used to be that leaving the machine on was 'easier' on the components, specifically the PS and motherboard, than the huge voltage shock that spiked a 'cold' machine. I taught computer classes for 18 years, and used to tell people who asked that question that I never had a PC die on me while it was running, but have had them DOA on startup. This was true (and remains so, even today).

HOWEVER, I believe the advances in PS and mobo technology have eliminated many of the reasons for leaving a PC on all the time. The only thing that I worry about on a start is the HD spinning up. Since it's really the only device with mechanical, 'moving' parts, HDs are still prone to more faults than any other component on your 'puter. The only computers I've ever had fail on me could be traced to bad HDs that worked fine while the machine ran, but would not fire up the next day.

I leave mine on 24x7 and just turn the monitor off. Same practice since 1983.

I cant turn off my monitor, the power button is shizzled, so I jsut turn the contrast down, and eventually it switches off after an hour or so.

My 2 home gaming PCs and the old one I use for a server never get shut down. The VAIO has been running for 4 years straight, with only being shut down to upgrade or clean.

In contrast, the computers I use at my office are shut down every night and my laptop gets booted up multiple times a day.

Besides the occasional rare fan or hard drive problem (as has been mentioned), I haven't had a problem or noticed a difference between doing one or the other.


I need to show someone that running a PC game and winamp is not gonna destroy their CPU by overheating it.

Most nights I have an online game running (rather graphics intensive stuff like DAoC or HL2 CounterStrike), music playing, Ventrilo/TeamSpeak going, and on many occasions my Opera browser sitting in the background to alt+tab to for information.

Most online gamers are going to AT LEAST have the game, music running, and a communication program running on their machine.

Trust me, a typical PC game and WinAmp won't cause many modern boxes to break a sweat.

Most modern computers have a thermal limit anyway at which the system powers down, usually selectable in BIOS. Pentiums have thermal management built in. Unless you're unlucky enough to have a POS like a Compaq or HP or lower model Dell, you can often select where it will will warn you (temperature wise). Look up a program Motherboard Monitor 5. MBM5. It doesn't support some of the newest boards, and requires finding out exactly what kind of motherboard is in your computer (or at least what thermal sensors it has so you can select a compatible one).

Either way, it's like a car. Its cooling capacity is designed to be able to handle the maximum amount of heat your machine is capable of generating during operation, barring malfunction. There's nothing you can do to heat it up too much compated to running ONE game anyway.

You should show your friend a CPU usage monitor during his different tasks, to see that 40 concurrent downloads would not use more CPU power than a single game or music playing.

Yeah it's mostly been said, that's ridiculous lol...Maybe show this person this thread and all who support it? It's actually entirely possible for a CPU to fry...but it has NOTHING to do with how much it's used. If a CPU fries, it's a design flaw. Computers are like northstars...they're designed to run WOT all the time :thumbsup:. Just to be sure, I don't cheap out on CPU fans...the thing is as bit as both my fists, and it has a built in temperature sensor and varies speed... Those Thermaltake or whatever fans only cost like 20 or 25 bucks. A CPU is like a Caddy with a 75 mph speed limiter built in... CPUs don't allow themselves to be run at any dangerous capacities unless you overclock them.

Might also mention that running multiple programs simultaneously does not necessarily mean the CPU is going to be using 100%. If the programs aren't complicated, chances are it won't. Running multiple programs just uses RAM. It does use CPU power, but the CPU is not the weakest link unless you're running games or video capturing or something...and even then, it won't hurt it. And, you can run out of RAM, and the worst that's going to happen is you'll crash... The only thing I would do if there is a lot of activity on the computer is set up a defragmenter to run every night... Lots of reading and writing on a hard drive without doing that occassionally can possibly foul it up.

The CPU won't overheat or die if you load it up 100% so long as it's not overclocked and is adequately cooled.

Intels won't burn up usually and the newer ones will throttle themselves. AMDs will burn up quick and fast without adequate cooling.

Turning a hard drive on and off is bad for it.


Explain it to your computer illiterate friend this way, say there would not be a taskbar if it was not meant to run several things at once. Tell him I use to have well over 100 things open at any given time and all of my computers have been fine, just fine.
