POSTed cpu without cooler, temps went up to 100c, I left it in the BIOS for 2 minutes. How bad of a situation am I in?

[jazzguitar1440]

Hi, 
I'm water-cooling my build, and do not have access to an air cooler, but I wanted to check and make sure my components worked. 

Therefore, I posted my computer without using a cooler on my cpu (10900KF). I left it in the bios for 2 minutes, and the temp went to 100C and was running at a frequency of 3000mhz. Realizing my stupid mistake, I turned off the computer, (the computer didnt crash) 

Temps went back down, and the IHS is cool to the touch . Also the pins on the motherboard do not look hurt. 

My question is, did I ruin my cpu/motherboard and how can I tell if I did?

Thanks

you cant tell till you boot it up, you're likely fine though

I probably shorted the lifespan of the chip/board

CPU will thermal throttle and shut down if it needs to when it's too hot. I think you're fine.

[Coolmaster]

It should be fine, if it was in serious danger it would've shut itself off. Laptop CPUs run at 100 degrees all the time.

its most likely perfectly fine, the CPU can throttle down by a lot to save itself

If you look at the graph it only decreases your CPUs lifespan when it spends a significant amount of time at max temps.

It's probably fine.

 

Silicon will only age if it's running at high temps for a very long time.

 

I myself have run my computer without a cooler to test memory or some other things. I also at one point had an issue where one of the pins on the Intel stock cooler broke so the cooler didn't contact the CPU. That CPU is still going strong 10 years after in my brother's desktop

zero damage, laptops run at 100C all the time.

That chart says nothing about the lifetime of the CPU, that's a thermal throttling chart.

This chart has nothing to do with lifespan.

 

I accidently left a PC in BIOS for 2+ hours with no cooler on it... turned it off, put the heatsink back on, boot up and passed stress tests no problem. Will it last a little less long, possibly. Is it likely going to matter? No. If it was that hot, it would have shut itself down.

Yeah I'm surprised it didnt crash at 100C. I wish Intel put a hard limit at around 97C. This is going to bother me for a long time, such a rookie mistake. I appreciate the support everyone.

A lot of motherboards won't even boot if you don't have something plugged into the CPU Fan Header. Or at the least they give a warning.

 

But you should be fine. All modern CPUs have built in thermal protection. They will simply shut down when the temp becomes unsafe.

 

The days of this happening are long over:

Zero damage.

If this video is anything to go by, I think you should be fine.  (If the in-URL timestamp doesn't work properly on your device, start it at 19:36.)

 

 

Spoiler

If I remember right (been a while since I watched the rest of the video) he was using a Haswell era Core i3.  Also he didn't use the small FFT test in Prime95.

 

I'd like to see someone revisit this with, for example,

• a DE-HEATSPREADERED (almost said delidded but that may still include changing the TIM and replacing the heatspreader) i9-10900K, i9-10980XE, R9 5950X, TR 3990X, etc,
• on one of the cheaper motherboards that has very small, or better yet, NO heatsinks on the VRMs (like on AM4/LGA1200, a $50-70 board, I suppose you might have to take the heatsinks off the LGA2066 or TRX40 board)
• running a stress test (prime95 small fft perhaps? or is there another real-world test that's just as stressful?) that runs AVX instructions on the FPU.

Bonus points: put a 260+-watt-TDP video card through the same torture test, with FurMark - simultaneously.   (Also are there similar stress tests for other things like RAM, SSDs / HDDs, networking hardware, sound cards, RAID cards, PSUs, (what else did I forget), etc?)
 

Oh and I almost forgot ... do it in a place where the AMBIENT temperature is warmer than the warmest my cousin's house has gotten in summer (It has, on another occasion, hit 1°F higher than the "max" indicated on the thermometer),

using a PSU with a temperature rating at least 8°C LOWER than the ambient temperature.
