Hey,

So I bought an extra 140mm rad but am finding it hard to decide where to place it.

Do I place it on the bottom intake? This could increase temps inside a little?

Or do I play it hanging outside the case on the rear? The only thing with it being on the rear is that it will have to hang outside the case, I dont think it will fit inside!

Unsure!

So from this picture here, it's either the bottom right one, or the top left one ( I already have a 360 rad at the top ).

(The picture is a random one from google, and doesn't represent my air intake/outtake etc.).

If you put it at the bottom over the intake area I found my temps got worse. I put a 120mm rad directly under the 140 fan on the mid plate and it wasn't too successful. I didn't use the hot swap bay as I found it temptemental so I removed all the inner drive bays and the hot swap data plugs. I then cut a hole in the sata cover put a fan inside as intake and mounted the rad ire rely in front of the Gpu. See my 800d thread for pics.

Obviously you can if you use the drive bay though.
 
Yea this is what I was worried about - I may just stick it on the back for now, and find a way to stick another rad in.

Perhaps If I had both in it would be ok - the problem is my Sapphire 7970 chucks out a load of heat in the case, and it warms everything up (which is why I need the extra rad), so I need to either watercool it (which currently isn't possible properly), or just trade it for another 7970.
 
I take it you have the vaporX? As from what I can make out its the only 3GB Sapphire 7970 thats non-reference.

1 x 120mm per component is the rough guideline, so if its just CPU+GPU then you shouldn't need to worry too much about the 140mm rad provided you have a 360 in the roof.
 
I got the Sapphire one that was on the Store Opening Deals, it's a Dual-X and is meant to be reference but they've actually changed it so no blocks fit lol.

Put it on the back, much better temps already :)

Have you confirmed this with EK? And do you know what changes exactly? Afaik the only two changes done by any AIB since ref 7970 release was the extra power phase (7 rather than 6) and some slightly taller caps (XFX design change). Blocks were compensated for both of the above.
 
There's two new caps on the left-hand side just off from the memory chips that were added, and because they aren't there on the reference board it means its unable to be fitted.

There is a thread somewhere but I'm not sure where abouts it was!

Just had a good game of trying to release all the air in my radiators, put about 20%-30% extra coolant in and now temps have dropped by about 10C (both Water temps and CPU/GPU temps) total with just this additional radiator.

A universal block would work, but not having anything on the VRM's etc would worry me slightly.

I'll see if anything comes of this issue with the waterblock, maybe there's an easy way around it.
 
I see now, that sucks :(

Would seem the easy way to tell if your cards are the new 'non-ref' is by PCB colour.

Edit: From reading that XS thread, it seems do-able to mod some FC blocks to fit, but its a gamble on a £70 block that would be rendered useless if the mod didn't work.

It is doable as you say, but nobody has done it so far, and I'm not risking a block on it :).

I've checked my card and I can see the capacitors, so unfortunately mine is one of the ones that suffers from the problem!

Perhaps Koolance or someone can make a block for it, we'll see how that thread pans out!
 
I'm not sure anyone will go out of their way to make one tbh, the market is extremely small :(

In your shoes, I'd sell on the card you have (hell you'll probably make a profit given the price you paid for it if you sell in the right places i.e. NOT the MM ;)) and buy a known compatible reference card.
