Longest you ever ran a cpu with no fan

not talking bout old xt-386 days, I'm talking bout the new burn your hands in 3 seconds after turning it on type. Just came back from lunch only to discover that the new intel 800mhz I just put in a guys machine had no power to the cpu fan (oops). lucky it was only bout 45 min. Before that was a pPro left running a burnin for 8 hours with no power to the cpu fan (I'm really bad for that). Luckly both processors survived the ordeal. How bout you guys (and gals...woulden't want PcPrincess to tear a strip off me too)

In my personal copmputer, after fitting a new hdd, didn't notice that i had accidently pulled the power to my intel 233mmx cpu fan. wasn't till about 4 months later that i discovered the fact, but it still ran fine. And I use it almost 24/7

Well I had an old 286 for about 6 years - ohh wait - I'm sure you mean newer stuff requiring a fan - Cyrix 6x86 166 - for about 6 mo., celeron about 6 mo, p2-233 for 2 hours to show my boss (at the time) that you couldn't send out machines without the $5 fan.

------------------
Death is lighter than a feather - duty heavier than a mountian.

I've run an athlon for about 3 hours without one, just to see how hot they really get.. (They get HOT!) But I've been running a P-5 133 for about a year now with no heatsink - no problems.

I once ran a celeron 433 ( i think ) without the fan plugged in for a few hours ... un-intentianally of course..

In the office, we have a P166, running without a fan at all. It has a small heatsink, but thats it. Its been running like that for about 18 months, Im told, and its also the most reliable machine we have. Go figure.

you didn't say it couldn't be under clocked!!! i ran a pIII 600E on a 66 bus without a fan for 2 hours....but why the hell would any idiot want to run an under clocked processor

I did the same thing. Built a machine, loaded Milli on it, started the burn-in when I realised the fan was not plugged it. The heatsink was hotter than heck but no harm no foul! Plugged the fan in and tested the cpu...all is well. Phew!!

You spend your whole life believing that you're on the right track,
only to discover that you're on the wrong train.

I can't believe you guys (and gals???) run your cpu's without fans or heatsinks just to see how hot they get! I made the mistake of using a couple of cheap fans on Cyrix M-II's and had to replace every chip 'cause they kept on crashing, even with new fans. I know have the best fan & heatsink you can get on my Athlon and it never locks up or slows down (AND I RUN ME).

Besides, keeping it cool is, well cool. https://forums.windrivers.com/

Well, when I was upgrading my T-bird 800 with a new CD drive, I accidentally yanked the fan connector loose from the motherboard......I thought I smalled something, ya know? But I thought it was the new burner warming up. Anyway, after about an hour I got curious, and had a look...oopsie!

It still runs great though, even though my wonderful, godly, heavenly Agilent ArciCooler was burning hot to the touch...but I think that thing is what saved my CPU....it managed to cool enough with the ambient airflow. Jeez, you know those things are STILL hard to get, but they're great. https://forums.windrivers.com/

Don't **** with me, I'm running LINUX!

An AMD K-6 2 500 for over an hour. If it wasn't for the large heat sink, I'm sure it would have been toast.

I've seen various processors running without actually being cooled, because the fans were not working.
The funny thing is, I've never seen a fried processor because of a faulty fan!
Probably, the error messages and the blue screens had prevented their users from leaving them work for hours! That's the most logical explanation..

Had an old P100 server running day and night for several years... but no heatsink or fan on the CPU! There was a brown spot in the center of the chip.

It was working flawlessly (up for something over a year) Added a heatsink and fan anyways.

Had a friend who for some wierd reason tried to remove his socketed CPU as soon as he shut it off. He had a little burn mark on each of his fingers where he touched it. https://forums.windrivers.com/

If it ain't broke, and you try to fix it anyway, then it WILL need fixing!

We have a few Dell's kick'n around at work from an old tech's bad decision that doesn't work there anymore. They are p3's @ 500Mhz with no fan, just a heat sink and some card board that is suppose to lead the hot air away from the heatsink up into the powersupply to be exhausted. Some brainiac was really thinking there. BTW, these are the only machines we have that multiple times on a daily basis.

I am currently running a dual Pentium Pro 200 with no cooling fans. Seems OK, but I will replace the fans shortly.

Is the damn thing plugged in, is the damn thing turned on?

not quite the same, but heard a tech tell me that he's seen baked k6-2's run fine. I'm gonna try that next week https://forums.windrivers.com/ https://forums.windrivers.com/ https://forums.windrivers.com/ https://forums.windrivers.com/ https://forums.windrivers.com/ https://forums.windrivers.com/

Ahhh nostalgia. I remember our 286-12 1MB ram, 40MB HD

When I was working at CR, we got in a bunch of Compaqs that had the heatsinks just glued on. On a couple, the glue had weakened, and the heatsinks kept falling off, often while they were in use! Whoops! They actually would run more or less fine without them, at least in the air conditioned store. They probably wouldn't have worked as well if I didn't keep the store temp at around 65. https://forums.windrivers.com/

Had a P120 come into the shop, no heatsink/fan, customer said the case had never been opened, must have been runnning for 3 years or so.

Had an AMD Thunderbird 800. No Heatsink/no fan, customer decided he would build it himself. Cracked the chip in half in 10 seconds or less.

It's not rocket science, it's just a computer.

I ram my AMD K6-2/450 w/a very flaky (sllloooowww, sometimes even stopping) fan for an unknown ammount of time, maybe 2-3 months as my Eudora mail server on WinNT4.0 sp6 Server...and it still does great to this day! But it does run 10 degrees warmer than my K6-2/550 box running WinNT 4.0 sp6 Workstation. Our Gw2k P-166 used the Power Supply fan to cool everything, including the CPU...so I added a fan-type heat sink to it....helped lots, much more stable!

Funny you should mention it... Just this past week I was putting together a PentPro200 to set up as my BDC at home (intend to set it up as a Proxy). I started to copy the i386 directory from the cd to the hard drive and left to go to the library. When I came back 2 hours later it was STILL copying files! There's only about 120 MB in the i386 and I thought "What the...". Wondered if the hard drive was hosed or something. You guessed it, the CPU fan was not running. Anyway I let it finish copying the files (it was almost done) and ordered a new fan/heatsink. It runs like a champ now. https://forums.windrivers.com/ https://forums.windrivers.com/ https://forums.windrivers.com/

If I want your opinion, I'll give it to you.

Ran my P3 500 with a non functioning fan for about 6 months before I realized it was really bad. CPU ran just fine, of course the case had 3 fans in it itself.

I've left a 486 on with just a heatsink for sometime. Much like everyone else.

When the pentium came out it got through a windows installation without a heatsink or a fan (I didn't have any at the time and was anxious to try the chip out). After Windows installed the vxd and memory errors came rollin in. Least I know what to look for if a CPU gets to hot.

I traded my Athlon 500MHz (Slot A) to my boss for an Athlon 700MHz... just recently he told me he killed it trying to run it underclocked, just so he wouldn't have to use a fan.

https://forums.windrivers.com/ I cried. I was so upset that he toasted my old processor.

This is an interesting thread in kinda the same vein that the old joke about stabbing your crab lice to death one at a time with an icepick is funny. If you're writing a book, this will make a great chapter, but I'm amazed at the response! :)

Ya mean.................on purpose?

You mean there's another way to get rid of lice?

Well, years actually if you consider the fact that Dell has decided they are special and don't need actual "cpu fans" per-say. They use that retarded case fan tunneled down to a huge heatsink. :D

We just chunked a load of Gateway PIII/450's with that same layout.

Just a little off topic, but I left my personal laptop on inside the carrying case overnight.
Dumbass me forgot I changed the setting to “stay on” when the lid was closed. Talk about hot, (both me and my laptop). Ran the battery completely down, (which was fully charged), and the fan actually burned out. The bottom casing near the cpu melted somewhat and so did the LCD. Cooked most of the other components as well. I was able to salvage the memory and amazingly the hard drive came out of the inferno undamaged. I now use it as an external USB drive with my new laptop.

I threw mine in the bag once while it was finishing the shutdown sequence. For whatever reasone (i forget why now, i think something was still open and asking for confirmation to close), it hung up on shutdown and ran in my laptop bag for hours until i pulled it back out. It was so hot to touch it dang near burnt me, but nothing got damaged luckily!

If I'm not in error, I believe that the Intel procs had a throttle back/shut down capability which worked pretty well. I fried an AMD Thunderbird 1400 in about 5 seconds. Those did run hot! The Intel procs did have good overheat protection in the P4's. By the way, my last Intel proc was a a Pentium 120. Amd ever since.

Heheh, I did something similar when I first got my laptop - I put dos 6.22, Windows 3.11, Windows 98, NT4 Server, 2k Server, 2k Pro, XP pro on it just to see if I could. Popped it in the case while it was still running dos and wondered why the case was getting hot while it was leant against my leg.... I forgot DOS doesn't hibernate :rolleyes: Fortunately it just wasn't fatal, but it did have me wondering what the heck to say to the nice support guys about how a 1 week old centrino lappie got cooked!

Yikes :D
I've had a Tecra S1 running in the case accidentally for several hours, and that never caused any sort of overheating like you described. CPU temp was about 65, but as far as I can tell its suffered no ill effects whatsoever!
