Here's a little tale of horror..
went to remove the ThermalTake K8 cooler from my Athlon 64 X2.
Unclipped it, tried to lift it....nothing moved.
Tried again....
nothing moved.
Tried a gentle slight twist(done it before)..
nothing moved
Tried to lift it one more time...
it moved in some style...taking the processor with it(glued to the heatsink base).
For some reason the Arctic Alumina compound(thin layer)had thickened up some and bonded the heatsink to the processor.
Not knowing what damage had been done/could be done I got a replacement heatsink and re applied compund to the cpu and fired up the pc.
So far so good, nothin gone bang yet.
Seein that I have not long spent £190 on said cpu(3800+)I was a bit more than put out.
Anyway, visions of a new motherboard and cpu have now faded.
 
I've had it happen many many times. First had it back when the Socket 478 P4s came out and my job was building PCs. Was a bit surprised to see the CPU come out with the heatsink but I didn't care as it wasn't my system ;) Still, I learnt my lesson after a few times - I now wiggle the heatsink around before lifting it up.
 
Just make sure you don't try pulling the HSF off when the processor is cold, needs to be warm otherwise it's a PITA to get off as you've found out.
 
So is it better to kick you PC in for a bit then switch off agin before removing the heatsink as this should heat it up.

I had that happen to me once I did not damage the cpu but I at to bend a couple of pins back in place. :eek: (scary)
 
Happened to me with X2 4400, it was terrifying. It seems the stock goop you get with the HSF had completely dried out, turning my pc on for a few hours made no difference, thankfully no damage was done though. Wiggling is the key.
 
It's happened to me twice, so now if I need to remove the HSF for whatever reason I'll use my PC for while first, leave it for a few minutes then take off the HSF. Hasn't happened since.
 
all most the same happened to me when i was going to replace a xp-120 coole rwith water cooling uncliped removed the heatsink with the cpu attached got riped out even with the cpu handel down tryed to remove the cpu by hand flew out of my hand and bounsed across my desk on to the floor, this was when x2 3800 were still in the 240/250 range spent about 45mins strighting about 20pins , to this day it runs at a ok 2.6ghz with the w/c gear
 
Happened to me once as well with an xp1900.. no damage done!

lol.. im sorry but i can't help but laugh!! ;)

this thread makes me sad :eek:

but cant actually say its happened to me once :confused: having got my new 3800 x2 i went to take my old 3200 out it had been with that heatsink for a year and it came off with no problems
 
I think it happens to P4s quite a lot. I was helping a friend over the phone and when he said "theres pins on the bottom of the heatsink and a plastic piece on the motherboard" I was like "er, what the hell, plastic involved in a heatsink?". Best thing to do is apply a hair dryer at a bit of range to the heatsink side until the paste stuff gets a bit loose.
 
happened to me last night, the cpu was epoxy bonded to the stock amd heatsink - probably a good thing as i could never get it locked onto the hooks right, so the paste was holding it in place!

took a bit of twisting the cpu to get it off, but all is fine now.

Had no choice as the fan was buggered up and I had no fan.
Have taken heatsinks off before when cold and never had it happen.

Better if no fan, CPU would've been hitting 60+ degrees in a few seconds. :)

Isn't Arctic Alumina the one that actually bonds?
 
Haha, reminds me when I had my P4 2.6, the same thing happend to me and my fan/heatsink was stuck to my processor, I pulled and twisted the fan and the fan broke off (snapped off completely) and the heatsink was stuck to the processor...lol

Anyway that made me upgrade to my current 3.6Ghz which should soon be dual 3.4Ghz (hopefully receiving it by tomorrow)
 
You don't need to boot the pc to heat it up. Hairdryer on the heatsink will apparently work.

I've never had problems getting heatsinks off, its getting them on and bending £150 worth of pcb while crushing £350 worth of cpu that scares me...
 
Prime 95 isn't much use if the pc won't boot, perhaps if thats the reason your replacing the heatsink or something, or if your part way through taking it apart.

Why does blowing hot air over a heatsink with a hairdryer create static?
And isn't everything grounded anyway?
