How long to fry a 1700+ with no HSF?

[Kuroyama]

It's a long story, but today I turned on my PC with a 1700+ and no HSF connected. I'm pretty sure the CPU was already fried before this, but after a few seconds there was a mild burning smell and I immediately turned off the computer. When I touched the CPU very briefly it burnt me (no surprise there).

The reason for my misadventure is that I thought I had previously fried the CPU by running it at 2.0V for 1 hour. However, when I popped in a new Duron the computer still failed to boot; after some searching I discovered that in a voltage mod that a pin from the voltage controller had been desoldered and lost its connection to the mobo. The 1700+ was running cold so I assumed it was already shot, so I put it in after fixing the voltage regulator and didn't bother with the HSF thinking I had nothing to lose.

My question is, is only a few seconds long enough to toast the 1700+? There was a bunch of old Arctic Silver II on the CPU so I'm wondering if that burning smell could have been the ASII, or if it was necessarily the CPU? Did my stupidity may have finished off my 1700+, or if say 5 seconds wasn't long enough and therefore it must have been dead already.

I think an xp chip will fry in a little under a second

@!?%+$

I guess this means I may have killed a perfectly good 1700+ and am now downgraded to a Duron 1ghz because of such a simple screw up :|

Sorry dude..it only takes a few seconds to fry an Athlon 🙁

Takes less than a second or two to fry up that
CPU. My relative says so cuz he works for AMD.

that was dumb

I now feel it pretty likely that my 1700+ was OK before my screwup (it's definitely toasted now). This sucks big time, but at least my new Duron 1ghz overclocks well. I've already got it up to 8.5x150 (1.95V / CPU temp 43) and Sandra reports it's faster than a P4-1.6ghz.

I ran my 1700+ with 158FSB. I think I can't reach that now because the Duron uses a 3x PCI multiplier so the PCI bus is currently way overclocked at 50, the mobo doesn't seem to allow me to change the PCI multiplier but if I figure it out then I'm hoping I can get the FSB up to 158 like I had it on my 1700+.

i did the same thing with my 1600. im used to the days of 486's and pentiums, where you could test stuff without the heatsink on.
it took under a second, and a thin stream of black smoke came out and it smelled like burnt rubber. there was a burn streak across half the chip and bubbles around the edges of the cpu core. hee hee 🙂

well i rma'ed it to newegg and got a replacement, no problem. been running great since then.

About the time to hit the power button and think opps....
