is it good to remove IHS from the AMD64 CPU to archive a good overclockable speed????

thanks

to gain 10-100Mhz and risk a high possibillity of a dead proc? I'd doubt it

when factory warranty ady finnish, then i think up to u leh..

if u hv good cooling ...

just asking dont dare to do it too risky...

wut is IHS??? lolx...

Integrated Heat Spreader

u mean the cap that covering the real cpu core inside? walao! can remove wan meh?

Dont know about AMD but with the Intel Prescott the die is damaged once you remove the IHS.
And don't forget the IHS also serves to protect the die from outside forces/pressure/cracking.

As long the heatsink does not apply alot of pressure then i think should be okay.
ihs has 2 function, to spread heat, to protect the core.

if the heatsink apply too much pressure, say bye bye to your cracked core

wah ......so risky wan....better not to try it...

if u daman rich... y not??

If you bothered to read at XS, there's been too many cases of very little improvments and too often dead procs by removing the IHS not to be seriously considered. It's only considered if you're on a "silver bullet"/"one shot" overclocking run which you know will kill the proc

I removed my Sempron 2500+ IHS since its so damn cheap,using a razor blade and a hammer,the PCB is stratch a little but the CPU survive. But since I use stock HSF,I used back the IHS but with new thermal paste,temp drop between 2-5 celsius. But no increase in overclock at all (probably limited by my RAM or PSU)

not all intel are like that though

intel die will damage if u dono how to remove the IHS.
so many success story but then for the improvment they bring, i rather just leave it on.
i dont mind having 5-6 degree's higher than risking my processor.
a slight nudge, or even when applying pressure to remove the heatsink, u can break the core

yeah..better sit back with the factory settings or just buy good heatsinks..

If you want to try it and willing to throw away your chip if its dead during the proces,why not?

intel ihs removal that went bad

the core is "glued" to the ihs

@dabad : oledi got the surgery blade for IHS project bang?

What happened to Babyelf's project of removing the IHS on his FX57? Has he done it?

well, din saw him for quite some time already
dont know where he gone lolz

Hullo cooling peeps again. Yes I know I have lotsa questions but hey, it is here that we learn in the forum right?

So recently I read a few articles about IHS removal. IHS stands for Integrated Heat Spreader which is the square block you can find on an AMD CPU (I'm not sure about Intel cos I've never touched one ). It looks likes this:


Courtesy from jijau's thread.

Yea so the thing on the left is the IHS and on the right is the actual CPU. Yes, for those of you who don't know, the actual chip that does all the work and produces all the heat is just that small square in the middle.

Now here comes the myth. Or truth...
They say that removing the IHS so that your heatsink can directly be in contact with the chip in the center will help you better in the cooling performance. Does it really help?

Btw, I found smtg which might be a bad news to those who are keen on trying this out.

Yes, it will help reducing the temps in much much better, but still, there's one thing that you have to consider...

If you've removed the IHS, then the core will be left with no protection, and one slight mistake in fixing the heatsink will make you lose you're processor as the core is very vulnerable, and it's easy to break...

Even with some small break on the core, you're processor will be unuseable...

Trust me, you don't want to remove the IHS

actually, research has proven the removal of the IHS has shown drops in temperature, but not in significant values.
therefore, no1 actually removes them nowadays

Mine running naked..... can go as low as 0.85v / 28c n 1.42v /38c

Sounds scary...

Hmmm I guess its not such a good idea since DaRkSyThE says that it does not have huge difference in the temp drop.

But what happens if ur IHS is dented or not flat anymore (maybe due to changing heatsink many times)?

that might cause a slight prob, thats why when removing ur HSF, its adviseable to do it slowly.

I don't think the IHS is easily dented...
Unless if u fit the heatsink too tight, maybe it will, but seriously, i don't think it will be dented easily

Even the core inside, after take out, but the core stick at the IHS there...... yr CPU gonna R.I.P.......

my opinion is not to remove it! diff a bit only....lapped that IHS is better!

Any good sites to teach how to lap an IHS?

*btw sorry to the moderators have to combine my thread with this... I didnt know there was an earlier thread.. could not search for three character words I-H-S *

if i remember correctly, Xtremesysetms forums had a thread just on how to remove the IHS.
not sure whether its still there

i got the vdo to remove the IHS from DFI-street forum...
juz a simple task by using a razor blade.. but risky laaa..
dun do it laa.. if u love ur proc...

Don't remove it lar...very risky...

Before I buy my Pentium D 820, I am using AMD Duron 1.2GHz which it does not have IHS...that time due to my mobo got problem, can't boot, so I keep on plug in and plug out the processor as I not sure whether it can boot cause by my processor or mobo...dang...suddently, I push the heatsink too strong...there are some break on the die there... I quickly clean of the break part...then I reapply thermal paste and plug it back...after several try... it still an't boot at all, then I decide to use back my pentium III 800MHz before I purchase new mobo and processor...but somehow the old hp mobo seem can't boot into windows...so I install back the AMD proccesor and the mobo...then I try again to boot... it suddently can boot wor...eventhought the processor got little break at the edge...but unfortunately, the system can't boot anymore after I off my PC on the third day...

I am not sure whether my AMD Duron still can work or not, maybe just my mobo gone...but what I trying to say is, it is very risky if the core leave unprotect...

bro removing the ihs can give u a few degrees drop yes, but wats the point? u might actually get worse contact pressure coz of mounting/ suface iregularity. plus most people remiove ihs for extreme cooling only, like ln2 or dry ice or a triple cascade phase change.... anyway , i use to have a athlon xp that i romved the ihs, diffference in temp onlhy 3 degrees, no t much to justify warenty and chance of killing ur proc....

lol...i remember u were once in the lapping heatsink thread...there we got discuss bout lapping procs too, is same as lapping IHS....

yup, both method got their pros & cons, but which method cons that can get ur money flush down to the toilet??? buying a new heatsink or buying a new conroe/athlon fx

i have a friend in US currently doing this on his Opteron...no problem i guess...
hehe

but do it at your own risk...

luckily read this thread else really have to change to C2D

how bout removing IHS, lapped it and stick it back? btw, any idea how to stick it back?

maybe can try to remove IHS, lapped it nicely and risk free...., then put a little amount of AS5 at the core and use black epoxy to glue it back the IHS.
Wait the epoxy started to stick...then u can place the whole proc back into the socket and place back your HSF to giv it the pressure. After this, wait overnite for the epoxy to form. Then voila! u can now oc and test the temp!

Make sure you keep pressure on the IHS while the epoxy is fixing-later the thing is stuck, but there's poor thermal contact between the IHS and the CPU die (a common problem with some A64's out of the factory, which is why some OCers remove the IHS). Intel 775 chips' IHS are soldered on, so thermal contact is better (solder conducts WAYYY better than thermal compound), but Intel chips are plagued with uneven IHS (even C2D).
