it can be done.

it is just EXTREMELY hard. You have to melt the solder with out damaging the cpu. I've seen people take a blow torch to the heat spreader (bad idea)

only way i can think of doing it somewhat safe, is to use the gold old oven. I don't see Amd using some solder which has a higher melting point higher than what the core could handle with out damage. So 180 degrees-240 degrees F in the oven should do it. Note at the higher end (248 to be exact is 120 C. Beyond that temperature the silicon will be damaged.

I might experiment with a dead cpu sometime in the future. Either way i don't think its worth it.

If one day my CPU dies or gets too old i will try do to it but not atm (can`t afford experimenting) biggrin.gif

Nothing like Thuban nb overclocking. You will however get much performance from core frequency and ram frequency on Bulldozer. biggrin.gif

got my piledriver coming tomorrow so im not really worried bout it

Yeah, it's not really worth it. Even on Ivy, the purpose is to put high quality TIM under the IHS, and then set it back on. So unless you want to run your chip without the IHS, and the fact that it's soldered and has good heat transfer, makes it pointless.

Running it without the IHS is very dangerous anyways because you can crack the CPU.
(I've only seen 1 review of an IvyBridge user without the IHS at all, and it was maybe 2 Celsius lower than just changing the TIM under the IHS)

HEY guys u know far cry 3 came out n i was curious of the cpu usage so while the game was running i alt-tab to check the task manager/performance tab and out of the 8 graphs . SIX were active the other two was not active . SO i dont know if the game operates like that. Has any one experienced that? TRY it n let me know smile.gif thanks:thumb:

have to check out... still... it is one of the MOST DEMANDING games i have ever played... that rendering of the jungle surely asks for some enormous workload

its not dangerous. Cpus didn't always come with heat spreaders. You just mount your cooler with care. A lot of today's heatsinks are not capable of mounting on a direct die, because they are designed with the heat spreader in mind. Ivy Bridge heat spreader is not soldered, and between the cpu and the heat spreader is a layer of crappy tim. Replacing that with quality paste a lot of people have dropped their temps a good number.

removing the heat spreader entirely drops temps usually 3-4 c. Just ask the ivy bridge guys.

Anyways on AMD cpus its pointless to remove the heat spreader because its soldered for one, and two it doesn't use crappy tim, its solder. IF you could remove the heat spreader safely and run direct die then a lot of extreme over clockers would do it. Including myself. The fact that it is soldered pretty much makes it extremely hard to do with out bricking the cpu.
