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?
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!

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

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

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

really wrks ka? freeze it?

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?
I was trying to be sarcastic-lah!!!

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

can arcticlean remove epoxy?

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

Good question!
Anyone?


Syringe!!!

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.

Reapply the paste because maybe the original one hardened and cracked?

change to copper sinks??

Try rotate it (if possible) rather than pulling it

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


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


Good idea! 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?

i mean, if you're able to remove the glued ramsink... can arcticlean remove the epoxy residue?

between the ramsink of course impossible la

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

airflow in the casing is also quite important if u wanna cool it down....
changing the heatsink wont probably help much if the airflow is not good...
u may just try adding some fan to blow at all those heatsink and save the time and fuss to change it, which might spoil ur gc...

just go to get a 12 cm fan and blow into it, job done
quite no point to take out the ram sink with epoxy and replace it with copper ones
well, there will only some slight difference or almost no difference providing the airflow of your case isn't that good.

Rather than all this trouble why not try put a Vantec Fan Card underneath dude? Some of my customers tried this way & are vry happy w/ the results. 1 of 'em is norazwan who got 2 units for his dual 7900GTX

no doubt, copper is indeed capable of storing a lot of heat in it.
as compared to Alu, copper sinks will help in lowering the load temperature a lot !!
i'd say to go for it, but without doing any damage to the hardware and improve the airflow around that area:lol:


come on man, dont make me laugh......i dont wish to comment about this, but some people are so noob and they just simply make the wrong decision all the time.

have you considered that he's using SLi setup man ???
he's just wasting his money on the 2x fan cards because there are simply no space for air circulation in between the two cards.

fan card is definitely a NO !!! for SLi setup !!!!

================== 7900GTX(1)

fan card 1

================== 7900GTX(2)

fan card 2



* fan card 1 will suck hot air from the back of 7900GTX(2) and blow it on 7900GTX(1)
* hot air from fan card 2 will recirculate back to fan card 2
* the fan card will block air from coming in from the side

graphics card releases heat from all direction.
the best way to cool down a SLi setup is still blowing from the side, or blowing from the end of the card to and exit through the PCI holes.


i seriously felt sorry for him for wasting his cash because he had listen to your solution
