Ugh. Just got an i5 4690k processor from Intel. While taking out the cardboard the clamshell case fell on the ground from around 2.5 feet. Upon impact it opened up and the processor fell heatspreader-down on the ground. I can't see any physical damage myself. I'm not too sure if it hit the resisstors on the back but I'm praying it will post when I get my mobo tomorrow. Anyways, tell me what you think and what other precautions would be good to take. Thanks!

CPUs are usually quite hardy. I've test-dropped an old dead C2D for a similar thread a while back. No physical damage whatsoever THROWING it quite hard on the ground. Even banging it constantly on the edge yielded little result.

Put it in the motherboard and start it up. If it POSTS, great! If not, bad luck :(. You may be able to RMA it as DOA to Intel or the reseller if the return period isn't up, but don't quote me on that.

If it does post, run a stress test like AIDA64 or Prime95 to ensure the system is stable. IF the system doesn't freeze, crash, BSOD or do any other weird things after a few hours running a CPU stress test, the CPU is most likely fine. Other than that, there isn't much you can do. The only way to see if a CPU...

Alright, but while inspecting it I ran my thumb across some of the recessed contact points for the pins. While looking at it with a light I can see a thin film of gunk in the little recessed parts. Blowing on it and rubbing lightly with a clotch didn't really help. Will it not be affected?

DO NOT DO ANYTHING!

By running even your thumb across the bottom of the CPU you risk damaging it! A cloth is worse; both cause ESD build up which can easily kill PC parts. Leave the gunk as it is and don't do anything further.

I ran my shirt over it quite a bit and blew on it some. Is there a way to release that? I have an antistatic bag if that helps. Would it be risky to put it into the mobo like this?

Put it in the anti-static ad taking care not to touch the contacts, and let it be till tomorrow. Any static charge built up will be discharged by the anti-static bag.

Chayan, I've been looking at some other posts of people touching the bottom and people say to clean it because it could contaminate the socket. They said clean it with a lint free cloth and 91% isopropal alchohal. Should I do that? I'm worried.

If you are worried, you can. Anything above 90% isopropyl alcohol will work fine. Use a coffee filter soaked in it if you have one on hand. If not, a bit of thick tissue paper will be fine. Rub gently, but don't use anything more than light force.

Just wanted to update on this issue--I built my pc and it booted perfectly! I had a scare though, because the power button on my pc didn't work(thanks NZXT)... But yeah thanks for saving me from spending another 240 dollars on a replacement! :)
