wooooo there you never go clock wise only counter! its a 939 so it has an ihs. if its actually epoxy, which I doubt, it would bent the pcb befor ripping the ihs off. I really think its just old dried TIM, seen it many times. some heat and twisting or prying should get it loose.If it is an actual thermal epoxy, ive heard it is weakened by freezing it, not heating it up. If thermal compound, heat it up. Either way, keep it in the motherboard and turn the heatsink clockwise after you release the retention mechanism. Do not pull up or your cpu will come with it.
the bet the TIM has had yeeeears to cure.Ok I'll try putting it in a system and warming it up. First, I have to straight out some bent pins.
Like it literally does not budge. I've never seen a CPU this stuck to the heatsink before.
You got it wrong, never go counter clockwise. Stop spreading misinformation!wooooo there you never go clock wise only counter! its a 939 so it has an ihs. if its actually epoxy, which I doubt, it would bent the pcb befor ripping the ihs off.

op you could even mount it and get into bios for a few minutes to warm up then twist the heatsink off while the chip is in the mobo(power off first).

The trick is getting the cpu back in a socket without opening the cpu retention rod.
clockwise down under maybe
oh shit good point about the rod but it might be doable, ive done it. lift the rod just a bit and jam it in there.
the chip isn't in the mobo. if you use something wide under the edge of the chip you can pry upwards and it will pop lose without any damage, unless it goes flying...Had this exact issue with an old s754. Warm and twist. Do not recommend prying.
They will actually pull the cpu out of the socket without opening the lever, that's how much they stick..
Could be just really dry thermal paste that mated well with the cooler. I know the stuff that came on my am2 sempron cooler held like glue, and my dad tore it out of the socket trying to remove it. A nice tap (and I mean it–don't do even a half-swing, as it shouldn't be necessary) with a hammer on a screwdriver should get it...just have something soft to catch it so you don't bend pins.Okay, so I used a hairdryer and blew on it up close for 1-2 min, to the point where the heatsink base and fins got too hot to touch. The CPU still won't even budge. So is it epoxy?
Sounds like it. Take a razor knife blade and drive it in between the mating surfaces. Lap both surfaces after scaping off compound to mirror finish.Okay, so I used a hairdryer and blew on it up close for 1-2 min, to the point where the heatsink base and fins got too hot to touch.

Thermal epoxy breaks free at freezing temperatures. I really doubt anyone would do that on a cpu though. Usually used for things without retention mechanisms like ram chips on gpus back in the day.if it is a legit thermal epoxy.. gonna have to apply enough heat to get to the temperature breakdown point.. got a torch handy?

if its just hardened TIM soaking it in alcohol will soften it up to clean it off. using a razor blade to pop it off shouldn't do enough damage to worry about lapping it.Curious, whats wrong with freezing a CPU? Is it the potential water damage?
Is there a way to scrap off the compound off the IHS without lapping it?

ah yes, I did indeed mean to suggest that most people would not use thermal epoxy on a CPU.Pretty sure what he meant is that most people would not use thermal epoxy on a CPU. People freeze CPUs all the time with liquid nitrogen and helium.
Which part are you trying to save here? The CPU or the heatsink?
Regardless, I'd use a skinny drift pin punch and a hammer. Rest the punch against the side of the IHS, in a spot where there aren't any SMDs for it to mangle and give it a tap with the hammer. Maybe put a towel or something around the whole deal to keep the CPU from falling and damaging the pins. If you don't have a drift, you could probably use a flathead screwdriver, maybe wrapped in electrical tape, so it doesn't mar the heatsink.
If one isn't a total klutz, it would safely recover the CPU, too. You're only applying force to the IHS, which is the part that's stuck to the heatsink.That's a great way to recover the heatsink, lol.
A thin razor blade works great; I just removed a bunch of epoxied 100W LED's this way.

good.The CPU (its worth ~$80) still.
I took it out of the freezer, and it literally popped right off! Huzzah!
Now to scrape this crap off the CPU and heatsink.
Glad to hear another successful freezer storyThe CPU (its worth ~$80) still.
