Ram Sinks on VRAM (air flow/fan?)

Building a water cooling setup, and I already have all the stuff I need (including all 16 OCZ copper ram sinks with Alumina Adhesive to put them on), but I'm just wondering, do you need any airflow over the video cards with the ram sinks? Like with a fan?
 
Depends on the airflow in your case.

A fan blowing over it won't hurt obviously but that also depends on how many fans you want in your water cooled rig.
 
I'd worry more about the voltage regulators/inductors than the RAM, I can sit and watch the temp sensor from the VRM on my X1900 hit 91º C due to the fact it has no active cooling anymore. I'm gonna be fanning that part of the card, I'm not worried much about the RAM. It seems to crank up to at least 800 w/o freaking out, and w/o fanning.
 
Depends on the total case cooling of course, but to begin with, you did pick the right ramsinks, but not the right way of applying them.

Use a mix of 75% artic silver and 25% artic silver epoxy compound. Use some nail polish remover to rid yourself of the sticky garbage that comes stock.

Yes, it would make it so you can clock the video RAM farther if you whipped some air on it. In another thread, they ask what's in your PCI slots. I've got an Audigy 2ZS in the last slot. Then I have a 120 mm Panaflo fan on each side of the video card with a 5 ohm, ceramic resistor to slow the speed of the fans.

First question, what do you mean "not the right way of applying them". Could you be more detailed as in, which AS epoxy compound? And whats wrong with the Alumina Adhesive?

Thanks
 
Nothing wrong with it and I'm asking you to use 25% of your mix for that. Use any more in the mix and you risk marrying the heatsink to the card forever. You'd feel kinda dumb at that point come rMA time if ever, that's all.

Ok, thanks. Because their website says to use 1:1 mix of it, but I guess if you don't want it on their forever 😉

Also, it's ok to use Artic SILVER on the ram right? Cause I got some Alumina Adhesive, as well as some Artic Silver Adhesive.

You shouldn't mix the two.

I ment mix the two tubes that come with the Artic Alumina Adhesive. See?

So, your saying I can/should use this?
 
I've gone the 50/50 route and had lotsa trouble getting the parts to divorce and go about their seperate ways. The 75/25 mix is plenty unless you plan on housing your case gerbles in their too!

All I'm doing here is passing on the hard knocks I've learned and where does someone get the rubbish about not mixing the two? What... you think it might lead to dancing? I've got 2 years experience mixing the stuff and lotsa reports from others and never a problem.

Oh ooops. My mistake. 😱

I would go with the Alumina. But I don't know if you can mix the regular Alumina with the adhesive to weaken the bond so it's not there permanently. I know you can mix the regular Arctic Silver and the adhesive though.

The Alumina Adhesive comes with 2 tubs. Your suppose to mix them together so that in 5 minutes it harderns or somthing to that affect.

So, I should mix it 75/25?
 
Bump for same question:
The Alumina Adhesive comes with 2 tubs. Your suppose to mix them together so that in 5 minutes it harderns or somthing to that affect.

So, I should still max it 75/25

Don't bother with ramsinks, just point a quiet 120mm fan at the video card and problem solved. That is, if your video card doesn't come with ramsinks in the first place.
 
Just to clarify, what you do is take the two part epoxy... you mix the two parts together... then you add three times that much regular artic silver to the mix... then you do the hoky-poky and you mix it all around!:Q that's all there is to it!
 
I don't know what all this talk of add regular artic silver to the mix.

This is what I got

It's the ALUMINA ADHESIVE (the non conductive thing).

I just want to clarify that you want me to add conductive AS5 to the Alumina Adhesive?!? (which I got casue I didn't want it to be conductive.

So, since there are two parts, part A and part B, which one do you want me to add 3 times as much?
 
Originally posted by: Seer
He's saying Part A and Part B will be 12.5% of the mix EACH (for a total of 25%), then add 75 % AS5.
Click to expand...

So it's safe to mix the Alumina Adhesive (which is non-conductive) with the AS5 (which is conductive)?
 
I think they misunderstood the product that I bought.

I think everyone here thought I had the Artice SILVER Adhesive. So thats why everyone said to mix it.
