Don't know if this of any help in this particular debate....?

But, like sticking ones hand into liquid nitrogen or touching red hot metal with a bare (But wet) finger. What everybody always knows to be true isn't necessarily so....!
(Sorry about the soundtrack and camera work, And I still wouldn't do it on a system I wasn't prepared to lose!)

Have done it in the mast with an E6600 i think just because i felt like it
Stayed on about 10 seconds and shut down
No damage but obviously not long enough to do anything
I doubt you'll be able to get it to stay on for any useable amount of time

Quicky nip into the BIOS and watch the CPU temp very carefully?
Of course not. It is fun for a sort of experiment (If you are rich enough for such entertainment) But I wouldn't dream of doing anything like this with anything I valued.
Earlier I was trying to find out what he thermal characteristics/power was for the old 486/586 CPU's was (The last ones I can remember running without heat sinks) and see how they compared with current processors.
Obviously a modern CPU cannot run under load without active cooling. The question is whether one can Boot and then go to a safe condition with a current CPU without any active cooling? I suspect that this is basically down to whether it can go through the boot process and then go back to idle before it runs out of the thermal inertia that might stop it from cooking itself.
And I suppose that is really what the OP's question was.

ok i can confirm ( AS IN IVE DONE THIS ) i have run a cpu without a cpu cooler .
it was a athlon 3700+ it had 3 case fans .. the custom cpu cooler had failed on it , but was running it fine for games for months on end .
no will this happen in more modern cpu ... not sure , but cant see why not
i will add , the custom fan was stil. on it and not bare cpu showing . cooling paste was on etc .. just fan not working

to be fair, ive seen my mates pc running windows 7 with 4gb ram, 2500k and an ssd without a cooler or a case - had it running for around 10 minutes. You should be fine for posting to the bios but yeah, dont recommend streaming movies or surfing the net while theres no cooler.
Why don't you record you doing this with your own CPU just to show us exactly what you mean?
Then I can laugh when your CPU goes pop before it even gets to POST.
OP: There aren't mixed answers, there's no chance of the CPU surviving unless you've smothered it in thermal paste completely.
I have done this before (mostly all Sandy Bridge so a lot cooler). Thought I would try a hotter chip, so I dug out an old Core2Duo (an E6750) took off the heat sink filmed (it out of focus first time playing with video on new camera, I didn't do so well! Only noticed after I had tided up)
Obviously don't do this if you care about your chip! But I just wanted to show all the people saying that it will burst into flames and melt the earth that these CPU's are pretty resilient to even the most stupid treatment! I only had it on briefly as it will shut off as the thermal shutoff kicks in! I think the beeps are no CPU fan detected and the BIOS message was saying the RAM had changed size!
Disclaimer don't do this! If you repeat it and break your chip its your fault!

I wouldn't want to buy a CPU that someone had run without a cooler attached, even for a short period of time. Think how long it takes your CPU to go from idle temperature to load temperature in normal use WITH a cooler attached, then realise it will hit thermal throttle point within a second or two without a cooler attached. The chip will basically try to slow itself right down to try desperately to stop causing itself permanent damage.
To my mind this is very much like draining the oil from a car engine, then starting it and running it at half throttle for a while to make sure it's still OK before selling the car on. It may not kill it straight away, but it sure as heck won't do it any good!
Ask the person you're selling the board to, make it their choice - if they've got half a brain they'll be happier taking the parts as is and assembling/trying themselves.

Also this a million times over! I wasn't trying to prove you should do it! Just demonstrating it can be done with a chip that isn't going to be used any more!

Your post appeared between me starting typing and finishing (curse my slow fingers!). Just watched your video and it looks like it does take longer than I thought for the chip to heat up to throttling point. Thanks for doing that - I learn something new every day around here.
Gee, people. It's not AthlonXP age. Intels (if it's an Intel, obvioulsly):
* do have thermal solutions,
* motherboards do have thermal solutions,
* are pretty cool, not warm.
Of course nobody advices hours of working, but 2-3 minutes testing. Booting to BIOS should be completely safe, but nobody can guarantee how long would it work as motherboard when CPU overheated disables whole PC. It would be better idea to set up in BIOS: lower speed & lower voltage BEFORE taking out the cooler and test it this way further.
If you are not brave enough, put any old radiator with some thermal grease on CPU, if you've got one (presuming motherboard is located horizontally, not vertically).
+1 Should be ok at idle for a couple of minutes
If you've got overclocked BIOS - it's definately bad idea then.
If you've got Bulldozer = it's not recommended as well
If you have a reason to need to test it then put the cooler back on first!
If you're just being paranoid then leave it alone. If I was buying it from you I wouldn't want you to run it without the cooler just before giving it to me!
