Duda refrigeration VRAM Graphics Card

[splendid11]

Hello! I have an Ati Radeon 4650 that had a failing fan, so I replaced it with an Arctic Cooling Accelero L2 Plus fan, which comes with some small heatsinks for the memory on the graphics card, and I was wondering if they are necessary to cool the memory.

Thanks!

Hello,
The Accelero is always a better heatsink than any reference one, and I think those little heatsinks are an additional complement to make the cooling more efficient. If the stock cooler didn't have heatsinks for the memory, it's logical that the ones that come with the Accelero aren't necessary, but it's always advisable to put them on since you have them, if they don't bother you…

Best regards

Thank you for your response! The problem I have is that the putty that comes with the new heatsink to attach the heatsinks to the memory does not harden and therefore they are not well attached and fall off. The instructions said it would take about 5 hours to dry and it has been since 12 noon and it has not dried yet and that is where my doubts come in about whether to put them on or not because the standard heatsink did cover the memory.

[Sylver]

Well, if the stock one covered the memories, figure it out somehow if you see that the thermal paste doesn't dry, but it would be advisable to put them on. The fact that the reference heatsink managed to cover them by making contact means that it received part of the heat they emitted and helped them to cool down. Actually, what gets the hottest is the GPU itself, but in that graphic you can't rely on it, the thing is that you attach the heatsinks as best you can.
Do they have thermal paste or a silicone-type adhesive like in the classic chipsets?

No, they don't carry anything. I read on a forum that someone had a similar problem and they recommended a small drop of superglue on the ends of the memories and thermal paste in the middle, although I don't know if the cure will be worse than the disease with that solution.

[Sylver]

Well yes, you will have to make some adjustments, the best thing is to use a drop of thermal silicone or something similar. There is a type of thermal paste that has silicone properties and once they dry they do not come off, this happens with some CPU coolers.
Certainly, I do not recommend superglue in any way, because if you ever decide to remove the coolers from the memories for some reason, it is very likely that you will end up damaging the graphics.

You can buy a tube of adhesive thermal paste, or you can mix a drop of glue with the normal paste, but very little or you won't be able to peel it off.

The adhesive thermal paste costs 15€! the ones I have looked at, it almost costs me as much as the fan, so I will discard that option.. will it be safe to put a drop of glue on it?

a small drop of loctite in one of the corners of each memory module, if you can buy the loctite that comes with a brush.

@splendid11:

If you have extra thermal paste, mix a little with a pinch of glue, it will make it stick, if not, try it on top of something else rigid to see what adhesion it gives you and know how to make the mixture, and that there are no lumps because if only the glue contacts it can make that when you peel it off you rip something off the plastic that protects the memory. It's basically what the adhesive thermal paste is, it usually comes in two tubes and you mix 50/50 is epoxy with thermal paste.

as far as I know, the heat sinks for the memory come with thermal adhesive
but in this case, it comes with adhesive thermal paste, it comes with two sachets of paste, one white and the other gray or silver
one is the paste and the other is the desiccant, please read the manuals

regards

[splendid11]

I left it to dry from yesterday afternoon until this morning and nothing has dried so I'm going to try the glue thing, I'll try it first on an old broken one so as not to make a disaster. Yes I have already read the manual a couple of times and if it comes with those two sachets that you have to mix for 5 minutes, apply them to the memories and put the heat sinks but as you can see it hasn't worked very well for me...

Thanks to everyone for your help!

[Franziskaner]

in any case, think that the paste does not have to look like cement ;D that tomorrow you have to be able to remove them without breaking anything more than once the CPU heatsinks have stuck to me and not because the paste was adhesive but because of the vacuum effect, so with those suckers I don't think you'll have problems. Loctite is the last option because if you put too much of it tomorrow if you want to disassemble them you'll surely break something (the memory module)

Well in the end I mixed the thermal paste and a very small drop of superglue and the truth is that it stuck pretty well, and it holds perfectly. I already installed the fan and it works wonderfully. I did a test with the furmark to put it at maximum speed and before it reached 75º at maximum and 45º at rest and now with the new fan at maximum it reaches 48-50º and 34-36º at rest so great!

Thank you very much to everyone for the answers! Regards!:D
