Is this CPU Fried? I5-3570K - New Build - Pics in Thread

To start off. Yes I'm an idiot. Now that we've gotten the obvious out of the way here's what happened.

Built my system. No signal on my monitor or my HDTV. Removed Graphics card, PCI Express Wireless card. Tried to boot from motherboard. No diagnostic sounds with speaker plugged in. Tried multiple combinations of ram sockets including 1 stick. Basically everything from this thread http://www.tomshardware.com/forum/261145-31-perform-ste.... Then decided to remove cooler and found thermal paste on CPU socket as well as half of the CPU itself. Thermal paste was preapplied on Corsair H60 (Should have used the freaking stock fan). Did use an anti static wrist band. Anyway here's some pics as well as my current set of tools to clean the CPU.

Motherboard is ASROCK z77 Extreme 6. CPU is I5-3570k

Cleaning items. Coffee Filters, 91% Isopropyl Alcohol, Microfiber cloth, Cotton Swabs


Please advise.

What thermal compound were you using?

Whichever one came pre-applied to the Corsair H60.



Also just to avoid any confusion. Computer is not on carpet. It's on top of an unplugged broken wooden bose subwoofer which hasn't worked since W's first term.

Do any lights come on or fans spin. how about system specs & do you have any paste?

The CPU has auto-shut off when it reaches TJ max. If it got there it should have kicked in.

Yes. The front LED lights were coming on. My cases power switch wasn't working so I was booting from the power button on the mother board. But all the fans were running including the 3 on my GTX770. H60 was also humming. Got no signal from monitor using DVI, HDMI, and HDMI. Monitor works with my laptop.

A quick look, for whatever that is worth, told me that the stock thermal compound, on an H60, is supposedly Shin Etsu brand. If I recall correctly, like Dow Corning, their thermal compounds are usually silicone based - they are non-conductive and non-capacitive.

Your motherboard, or processor, may be DOA. Do you have access to any other parts that you could test them with?

Not at this time. Fortunatly I do have a protection plan from Microcenter for the MoBo and CPU but I would at least like to give it another go. Whats wrong though with that brand of thermal paste?

All fans were spinning. I have a case of some generic paste and some that came with a Cooler Master Vortex cooler that I planed to use as a backup Cooler in case.....well something like this happened. Kind of wish I sprang for some Artic Silver but at the time I was just planning for a worst case scenario.

Plug into the monitor into the mother board video output until you can "enable" the card in bois. Did you install the mobo disk yet?

Haven't installed anything yet. Put the motherboard disc in but without a signal from the monitor couldn't do anything with it. Cleared the CMOS though while trying to figure out why I wasn't getting a signal.

Sorry, it's late at night; I should have been clear. Shin Etsu is a respected name in thermal compounds, and if your stock thermal paste is of their brand, then it probably is silicone-based. Long story short, your thermal paste probably didn't fry your CPU. Other than a select few thermal compounds, like Arctic Silver 5, very few popular brands are conductive and/or capacitive with electricity.

So really all I need to do is clean it off with isopropyl alcohol and try my luck with the stock fan?

Mind as well give it a try. Any damage that may have happened has already happened; can't really make it worse just by doing that.

For my current rig, I got a DOA Asus Motherboard that wouldn't POST. They, the customer support, told me it was a bad CPU. After RMA'ing, I found out it was actually the motherboard... But I have heard of people having the same issues with a bad PSU. Take that story with a grain of salt.

Anyway, tell us the results; I hope it goes well.

Best solution

Put it back together, pull the card for now & boot with the mobo. When it is stable you can put the card back.

So just an update. I cleaned up the cpu and the mobo socket. Made the stupid stupid stupid stupid stupid stupid stupid stupid stupid stupid stupid stupid stupid stupidstupid stupid stupid stupid stupid stupid stupidstupid stupid stupid stupid stupid stupid stupidstupid stupid stupid stupid stupid stupid stupid mistake of using a microfiber cloth to run over the pins on the motherboard (should have used a coffee filter) and some of the pins were bent.

Ironically enough the computer booted up after I installed the stock fan and was set to install windows, but given the risk I decided against it since the OEM copy of Windows attaches itself to the motherboard.

Went to Microcenter to replace the mobo through the protection plan and they were awesome. The rep said I was still within the return period so they just had me go get another motherboard and keep the protection plan. Was so thankful that I splurged on a 120 gb SSD, artic silver thermal paste, and a hard drive enclosure.

Now everything works perfectly. Will install one of my aftermarket coolers later but seeing as how I'm not overclocking right now I don't see any reason to use anything else.

Thank you to everyone who responded to help me out in my time of need.

It is by mistakes that we learn the most valuable lessons, no harm done. Sometimes common sense eludes me also, but we dust off and move on. Great news..cheers
