Possible CPU blown?

[WarmMilkMambo]

I incorrectly installed my heatsink (switched from stock heatsink to a liquid cooling) and after about 5 minutes or so, my computer shut off. The heatsink casing had burns on it, so im assuming my cpu was blown. I tried to boot shortly afterwords, and all the LED's and fans come on very shortly, but immediately shut off.
Is my cpu completely screwed, or will it be able to cooldown and be able to boot back up?
Thanks in advance!

Post your complete and detailed build.

Its very rare that a CPU gives up the ghost. But running a PC for 5 minutes without an attached heatsink might be one of those occasions.

CPU: AMD FX-8350 Eight-Core 4GHz AM3+ Processor
Motherboard: ASUS M5A97 R2.0 AM3+ Motherboard
VideoCard: Sapphire TOXIC Radeon R9 280X Video Card
Ram:Kingston HyperX Fury Red 4GB Desktop Memory Module x2
HD: WD Blue 1 TB Desktop Hard Drive
Heatsink: Corsair Hydro Series CW-9060010-WW H55 Quiet Liquid/Water CPU Cooler
PSU: Thermaltlake SmartM850
Oh, and my computer is currently not in a case, since I was testing if the heatsink was working properly

Was running Prime95 and then the computer just shut off, no bluescreen of death or anything. Last I saw was the Temp going up to around 65 degrees C.

I hope it was Prime 95 v 26.6. Other versions overstress the CPU. Why were you using Prime?

Per http://www.asus.com/au/Motherboards/M5A97_R20/HelpDesk_CPU/ - got bios 1006 or later?

Seemingly everything is correct, and I was using Prime 95 v26.6; it was a reccommended program to make sure for stress etc.
I have the latest bios. I discovered my heatsink had no Thermal paste on it........ and I'd rather not try to start it up again until there I get some on there

Don't stress the CPU unless you have a specific reason eg testing OC stability.

Yeah - I'd put paste on and give it another go. Watching carefully of course.

Will do. Thank you for the help man!

Good luck. CPUs are supposed to shutdown before they get damaged. Hopefully that's the case.
