Fried an XP, almost fried the second (small update)

Well,

I was doing some "routine" maintenance today (cleaning out the dust bunnies). I took off the heatsink from my main box, an XP 1800+, and cleaned out the dust from it (those things get filthy). I put it back on, but in doing so, I didn't completely seat the bottom clip I guess, because about an hour later, as I was working on the kids machine, I heard this kind of wierd "pop" sound. I wasn't sure where it came from, but my first and only guess was the stupid heatsink clip. Checked my screen on my main machine, and sure enough, it was dead, so I cut the main power. Looked inside, and my heatsink was loose. So, I reseated it, and fired the system up, and nix, nada, nothing..... Completely dead. So, I grabbed my spankin' XP 2200+ out of the kids machine and put it into mine, reseated the HS/F (Tugged on it a bit to make sure it was well seated) and fired my system. (This was an experiment, as I wasn't sure my MoBo would recognize an XP 2200+). Anyway, it fired, and booted up, ran chkdsk, and everything seemed fine. My temps seemed high, but I attributed it to the faster CPU, and didn't think much about it. However, as I was working on it (ordering a new XP 2100+ from newegg), I noticed my temps climb up to 70C, and as I was going to check them closer, my mouse locked up. So, I immediately killed the main power again. As I was checking the HS/F to make sure it was seated, I realized it was burning hot to the touch. That's when I realized I hadn't plugged in the fan for the HS/F.
So I almost lost my second CPU. Plugged that back in, and rebooted, which worked fine, and I was running normal, with slightly lower temps of 51C.

Those of you who don't think these Coolermaster HHC-001 w/heatpipes work, they work marvels. I was able to run my XP 2200+ for about 10 minutes without the fan connected, long enough to order a new CPU from NewEgg, before the system got too hot, and locked up. That's some pretty impressive bare cooling. For a fan, I have a Panaflo FB0812M1A (medium speed) using a 60-80mm fan adapter, set to suck.

The only good thing about this, is I will be upgrading an XP 1800+ to an XP 2100+, which I hadn't budgeted for, but hey, these things happen :D

********** Small Update *********************
I must say, I am most impressed with NewEgg. I paid the "rush" fee on Friday, when I ordered the replacement XP 2100+. Well, even though my order was placed about an hour after the "rush" cutoff, they managed to get it processed and shipped on Friday, and according to FedEx, it looks like it will be delivered today. That's nice. So, I will effectively be replacing an XP 1800+ palamino with an XP 2100+ T-Bred.

Folding on.................

That has to be a good heat sink ... normally you'd only have about 3 seconds to burn up an XP chip.

Not to start an Intel vs AMD battle ('cause I run both) but I did the same thing you did (forgetting to plug the fan back in) but on a P4. I noticed it started to slow down and eventually just shut down. I tried to start it up and it restarted but didn't run very long before shutting down again. That's when I looked inside the case and found out the HS Fan wasn't running which they don't do very well without some 12v feeding them.

The heat-sink gave me a blister it was so hot. I waited about twenty minutes until things got warm before hooking the fan up and restarting the computer. It's been running fine ever since. This is really one of the best selling points for the Intels. ;)

I almost lost an XP1600 one day when I forgot to plug the fan in.

The weird thing was that I was trying to load windows on the machine and it just kept locking up :p When I finally noticed the unplugged fan I immediately rebooted (so the fan would cool the HS and chip. I checked the bios temp immediately and it said "0" on the F and 99 on the C side :Q I hardly believe that it was that hot but still it freaked me out - I ALWAYS double check the fan connection before firing up a new build now :D Oh and both the chip and board survived:D - actually that box is now my mother-in-laws computer:p

I guess that's one of the few nice things about running a very loud cooler...
If I don't plug in my 7500 rpm Delta fan everybody in the house wonders why it's suddenly so quiet... ;)

I crunched on a p2-333 MHz with a dead fan a couple of days before finding out the wu-times was unexpectedly high...

Except for shifting some cpu-fans, this dual box haven't had any problems... :)
Ehm, not before trying to use an 80 GB hd together with win2k... Oh well, NT4 works great. ;)

I lost a AMD K6-166 when I forgot to plug in the fan and started installing Windows. The heatsink was really hot. Ouch! And just recently a cable blocked the fan of a P133, almost lost that one too. But after a blue screen I luckily checked and noticed the fan was not running. Took it away and it cooled down (froze tho). Puh :)

Fortunately, most recent AMD boards (KT333 onwards, and some prior to that including my favorite, the A7N266-VM) have overheat-protection circuitry. I can testify to its ability to shut off a CPU in less than a second if the heatsink isn't making contact when the power button is pushed :eek:

I had a couple Coolermaster HHC-001 and they are marvelous heatsinks... I polished them down real good before installing them and they gave me the best cool I had ever had and that wasnt using an ear popping fan either. They are excellent coolers.

That s*cks!!!

I once took of my hs on purpose from my PIV 2.0Ghz while a friend of my was playing Battlefield..
the only thing it did, believe my, was just slowing down!! And I could even touch the core!
The game did crash, but my mouse continued to move in Windows.. As soon as I reatached the heatsink
everything went back to normal.. In just a few seconds :D

I saw this test once on Tomshardware and wanted to test it myself :p..

Get an Alpha 8045 or one of them that bolts through the motherboard. It's a pain when you need to swap out the processor, but you can't really have it on loose, and it's so large that it'll keep the processor alive long enough for you to realize that you've done something really stupid, like leaving the fan unplugged.;)
Yes, I too have killed procs with heatsinks. The one was a Tbird 900 - the Chrome Orb (don't know what posessed me to buy that cooler) wasn't clipped on right; thought it was...smelled something funky after turning the PC on - the arctic silver on the core had turned into a reddish solid; the CPU was dead.

I once ran a Tbird 1ghz where I had forgot to plug in the fan for about 10 mins or more....didn't lockup....I was sitting there thinking "hmm....this is quiet.....uh oh....."

I did the same thing, but with a k6/2 500. It got so hot the heatsink kinda welded to the cpu heat spreader. I had to pry them apart with a screwdriver. That core was dead :p
