Hey y'all

Has anyone actually tried the hairdryer/vice method of delidding? I have watched about 20 different vids on YT now showing three methods;

1. Razor blade
2. Vice, wood and gentle knocking
3. Hairdryer and what seems to be a simple removal

Can someone provide feedback for me on whether they have tried 103 above?

Thanks
 
From the videos i have seen the hairdryer method looks less risky. On my 4670k i couldn't do the razor blade method even if i wanted to as there is no gap at all between the IHS and PCB. There were a couple of 4770k's that developed shattered cores after using the hammer and vice method over at XS forums. Whether it was just a coincidence or stressing the pcb when being hit by a hammer i don't know.
 
Not tried the hairdryer/vice method but have used the razor blade on 3570k and 3770k successfully. Just takes time and patients tbh.

At the beginning its hard to get the razor between the PCB and IHS but you soon get it under there and then it becomes easier.
 
Never seen that hair dryer method before, but If i had a 4770k id probably go for that considering using vice and hammer is more risky due to the tracers on the cpu die.
 
Used razor blade and patience on my 4670k - easy to do. Would probably choose the hairdryer method if I'd known about that at the time.
 
Hairdryer method imo

Did my ivy chip with metal blade on one corner,then used plastic spreader for the rest,you actually see the PCB bend,not for the faint hearted
 
Heating up the cpu and softening the compound looks like a good plan and should be fairly easy to do. Dunno thou if I would be brave enough to de-lid my cpu!
 
Still shudder at the vice and hammer method :(

Hairdrier method is the one I would try, a bit like changing a screen on a iPhone 3GS.
 
Only problem is you see one mention of the hairdryer method and if you watch closely he really torques up the vice on the IHS after heating it up. To me that says the IHS will be distorted and probably not useable.
 
Someone should test for a chemical that slowly dissolves the black glue holding the IHS on...but doesn't affect the rest of the cpu; just apply and let it work for a few weeks while you use pc.
 
I have done 4 CPU's now and I always heat up the CPU and then use a razor as I feel I have more control over what's happening. I normally stick the CPU in the oven at 80c and then start from there... a hairdryer to warm would be just as good though.
 
SayWhat? said:
For the people who have done this successfully. How much does the idle/load temps drop by?

From what I have read it can be anywhere from 20c to 35c depending how well the factory lidding has been done.. and how carefully you wipe away that black stuff + apply your own paste.
 
I thought you were joking when you said the 'hammer and vice' method, then I watched the youtube vid and almost had a heart attack. Hitting a 270£ CPU with a hammer !!!
Then I watched the guide one guy made, vid took 20 minutes and some was on speed x10, when he was cleaning cpu from old paste/glue, so something about 25 minutes total. He used the razor blade technique and to be honest it seems to be least invasive.
There are always some dangers.
Anyone tried joining the hairdryer method with razor?
Heat up the CPU and then work it with razor?
