Greetings to everyone, Sifoo's & Guru's alike.

I have a minor predicament.

Quite some time ago, I purchased an ancient gem, an Inno3D Tornado Geforce4 Ti4800SE (128MB).

Recently, when I actually found the time, I installed it & encountered some MAJOR overheating problems. Please refer to the link for more details.

Now, my actual reason for opening this thread is to get some clue as to HOW in the world I'm supposed to remove the stock aluminium ramsinks on the grapic card? unsure.gif
As most of you clokers out there realize, the most convenient (...or is it the ONLY?) way manufacturers attach ramsinks to graphic cards is via epoxy. Once on, it's on! FOR GOOD! vmad.gif

Therefore, I would like to gather some experience from the experienced-ones out there on the correct/best method of removing ramsinks off the VRAMs without pulling out the memory modules in the process.

I'm quite sure there are Sifoo's & Guru's out there who have done this before. PLEASE share you experiences for the enlightment of us lost-ones notworthy.gif

Thanks in advance!!!

Put the card into the anti static bag and freeze it for a couple hours.

Then quickly pry the sinks off, and pray tat the chips do not come out with it  laugh.gif

EXCELLENT ADVICE!!! thumbup.gif
But I think your method is to orthodoxed & "safe". Let's try something a little bit more adventurous, shall we? laugh.gif laugh.gif laugh.gif

Yup it works. Tried it before. Juz make sure to max the temp to the lowest possible.

Let's see, a more crude way.....mmm..brute force?

How about hammer & chizzle? doh.gif laugh.gif
I was trying to be sarcastic-lah!!! laugh.gif

Anyway, isn't there any better way to go about this? No epoxy-desolving solution or anything to that sort?
Any other safer ideas? unsure.gif

can arcticlean remove epoxy?

Good question! biggrin.gif
Anyone? unsure.gif

How do you get the articlean between the ramsinks even??

Y u need to remove it? If it doesnt come off easily by peeling means the bond is really good n it's doing it's job. Ure only risking damage by forcing it off.

To upgrade the the aluminium ramsinks with better ones. I guess it's the best option if I'm going to start clocking the card sweat.gif

Reapply the paste because maybe the original one hardened and cracked?
change to copper sinks??

Yup! thumbup.gif That's what I meant by "better" Bro. ianho biggrin.gif

QUOTE(bombman @ May 26 2006, 12:26 AM)
Try rotate it (if possible) rather than pulling it wink.gif

Good idea! thumbup.gif It'll definately put less direct force to the VRAMs.

As I was pondering earlier, aren't there any solvents to soften the epoxy & allow for easy removal of the ramsinks?

If ure going tru all that trouble n risk just to use copper sinks then I reckon not worth ure time coz for ram sinks, changing from alu to copper isn't gonna gain much. The epoxy oso shudn degrade either coz epoxy is pretty hard stuff n ram doesn't get that hot to degrade it.

Really? And based on what benchmark are you saying that the performance gains aren't "worth it"? Are you comparing temps based on standard clocks or on overclocked cycles? I'm curious, that's all Bro.

The way I see it, the main reasons for changing the standard ramsinks are to allow for better thermal conductivity between the VRAM & heatsink (by using better thermal contact material) as well as utilizing ramsinks made from material with better thermal conductive properties (copper, in this case). For me, the lower the temps., the better. At least that's what I think. If my reasons are totally wrong, please do advise notworthy.gif

Aluminium is better for passive cooling. If u opt for copper ramsinks u need to use a low cfm fan to benefit it. If not u might suffer degradation since the temp on the ram's surface would be higher. This is tested before, aluminium is good for passive and copper would be for active cooling. If you just changed it to copper without fans its going to be a bad idea. Trust me.

OK... THIS is acceptable.
Did some research, your statement holds quite true thumbup.gif

But then, assuming that one has to remove the ramsinks due to an aftermarket solution that includes VGA RAM cooling (watercooling for instance), how does one go about it? unsure.gif

Some of the newer cards (GeForce 6 series for instance) have waterblocks which includes cooling for the VRAMs as well. Then what? unsure.gif
