Accelero S1 rev 2 instalation tips on HD3850

post #1 of 10
Thread Starter 
Hey guys,

The thing is I have finally managed to get a hold on a Accelero S1 rev2. You wouldn't believe how hard are these to find in Europe...more specifically in France. After 3 months of searching I bought one from a guy on a forum, somewhat overpriced, but hey

Now, I'd like to install it on the HD3850 that could use some lower temps (90°C load!). The Accelero is second-hand, so as far as the memory sinks are concerned, they have no glue whatsoever, nothing. How should I tackle this?

My card is a Jetway, but the shape is absolutely identical to this one (skip the iPhone):

That's the one thing that I don't understand about the Accelero. They don't provide thermal adhesive. Some have been able to hot glue the heatsinks, but I wouldn't recommend that. Get some good thermal tape/adhesive.

I used AS5, about the size of a strain of 10 hairs. Held it there for 1min, then used a hair dryer to heat em up. They haven't had any trouble staying on.

Hot glue, for attaching heatsinks? Are you serious?

That has to be one of the most foolish things I've ever heard of.

Anyway, get some thermal adhesive, or leave the heatsinks off (you probably don't need them).

Well here is the tip of a lifetime ; What you could do is buy thermal tape; but I suppose that's hard to find too. So what you want to do is take whatever thermal paste you have and first apply a super tiny dot on each sink. and of course to seal them to the rams on the card you will have to use a tiny dot of super glue in the corners of the ram sinks. I've heard this worked for many people but do note that they will NOT ever again come off. So this is a once in a lifetime decision

Do this at your own risk! Then again you can always find and buy some thermal tape

That will work, and you can get them off, if you use a very conservative amount of super glue.

Thinned thermal adhesive will also come off, without damage.

I tried thermal paste on one that wouldn't stick which worked, but I would recommend buying new ram heatsinks.

Thanks, I appreciate.

From all of this I would take that super-glue-ing them on the card would be ireversable, and also quite against the principle of thermal conduction - super glue is a pretty good thermal isolator. Overall- not much gain.

Second option: AS5 in the middle + super-glue on the edges: the idea would be we still have thermal transfer on 80-90% of the chip surface, but also the heatsinks sticked on the card. Solition that is cost effective and possibly reliable if done right, since I happen to have a tube of AS5 and also super-glue real close to me right now.
@alexvasile Where are you from mate? I'm from Pitesti, I have the feeling that from your name (and the interesting solution) we may have lived at a certain point not to far from each other

High-end solution: thermal tape: reliable and effective, also involves buying a tube of thermal paste wich adds another 14-18€... too much at the moment.

Thanks, reps to all. Hope I'll get this right.

It is hard to find, even tho the headquarters are in Switzerland. The development team is there, but I'd bet the production is outsourced in China, Taiwan, etc...

In France they are seen like the best possible coolers, which I agree completely and they are also cheap. This makes that as soon as a batch appears on sale, it's sold out in half an hour, but after 3 months I've finally got one.
The irony is that for example 2 years ago when AMD launched the Brisbane DC (at that time still the best CPU) it took over 3 months to AMD to put them on sale in Europe despite the fact that they were actually designed and fabed in Germany. The CPUs are still packed in Singapore as far as I know, and this makes the original location of the company quite irrelevant.
