cpu dropped and crack

[xperikan]

Recently i just upgraded my processor from i3-3220 to i5-3570k, i bought it secondhand (still 4 months old). When i open it i found the processor covered by thermal paste on it side, so i decided to clean it, when i cleans it, accidentally the processor slip off from my hand and fall, the height is not too high about 10 cm, i check the processor and found this

Spoiler

Red line : a little gap, just a little, i hope it's okay

i've installed the processor on the board, and have running for 1-2 hours, with a little oc, nothing weird, but still i'm worried about that crack, is my processor okay to use, or should i take it to intel for a rma ?
Thanks!

Hate my self for dropping both of my cpus :?

Doubt intel is going to RMA a crack from a dropped CPU. If it works, you jsut cracked the PCB and luckily none of the traces that run inside of it. Very lucky. IF you broke something, it wouldn't have worked.

It is very likely that you won't be able to RMA it, considering that any tech would see that the crack is the fault of the user.

My advice is, if it runs, don't try to mess with anything. It appears as if only the PCB has deformed, and as you said that it boots with no issues, run a stress test like prime95 which is CPU intensive for a few hours and see if anything weird happens (PC suddenly shuts down, Windows hangs or freezes, etc.).

Also monitor the temps (though any change in temps is unlikely.) with something like HWMonitor during the stress test, and see if they are unusually high (70-75C is normal for an i5-3570k at stock speed with the stock cooler at full load.).

Okay thx for your response getochkn, i hope the processor could stand for 3-5 years 😀
Just wondering, many people said that cpu is hard, even when it fall from 1 meter high it would be fine, but this time, 10 cm crack the edge of my cpu?? Maybe mine has some defect ?

Okay, i will run prime95 for 24 hours to make sure, hope the cpu will be fine, and yeah, the temperature hit 79'C , quite surprised to see high temperature like that 😀

I still worried about the durability of this processor for 3-5 more years, since I'm still using 1155 board, it would be a waste if i buy a same processor in the next 6 month
Thanks!

For a mildly overclocked CPU, that temp is perfectly fine on the stock cooler. If the CPU works now, then I am quite sure it will continue to do so for the next 5 years, since it wont be moved around or anything to put extra stress on the cracked area. However, if you replace the cooler in the future, then take care not to put extra stress on the cracked area since it could break the electrical traces on it. The CPU is quite hard, due to the metal case it has, but the edge is the PCB which is made of some kind of plastic if I remember correctly, so it is not as strong as the metal case on it.

CPUs are quite strong, and i doubt that a 10 cm fall did that, is most likely that it was already like that, if is working now, you dont need to worry about it.

Just tested that theory with an old busted Pentium. Unless they changed the material, you are absolutely right, since I couldn't make a dent in the side with repeated hammering on a wooden edge, and only slightly dented one corner by dropping it from 5 feet.

Actually I've lowered the speed to about 99.97 mhz, since it support turbo boost up to 3.8GHz,but it still hit 90'c, maybe the room temperature affect the cooling system. It's nice to hear it could run for 5 years , I'm not an overclocker so i wont pull the fan, except for cleaning the fan. Thanks for your explanation 😀
Hope intel built a rigid processor next time 😀

I think like that before since i dropped my i3 from a higher place and no.physical damage, but it is only 10cm and snap.
I received it in a great condition, only a little thermal paste on the epoxy between heatshrink and processor
