Using a universal GPU block for a 7970. How to cool memory/VRM?

post #1 of 7
Thread Starter 
Hi everyone. I bought the Swiftech MCW82-7900 version to cool my Gigabyte 7970 (GV-R797OC-3GD rev. 2.1). This is what the PCB looks like:

Aside from the memory, the die, and the mosfets, what other remaining components (if any) do I need to cool for this?

I understand that I'll need to use copper heatsinks, but I'm a bit confused on what size and how many I should get. Can someone please direct me with the proper components I need to buy from FrozenCPU.com?

Thank you.

I have the EK Uni blocks on my GTX570's and used the Enzotech BCC9 / BMR-C1L Low Profile Forged Copper BGA Ramsinks

I used these because they fitted under the uni block.

The card looks similar layout to mine.

Hey, thanks so much! I'll use those too. Now, I need to stick them on the memory, as well as the VRMs, right? For the VRMs, I'm going to need what you just linked as well as those rectangular ones to cool the Mosfets, correct?

The VRM's DO NOT need them. They are under the silver coloured heatsink to the right on the card.

Some may say you should, But I haven't, and I am yet to have any trouble.

There is nothing else needing heatsinked. Just remember that you will need a small amount of air flow over the cards. For my setup I solely relay on air flow in and out through the vents already on the cards brackets.

I hope this helps, and enjoy the fact your cards will never break a sweat again biggrin.gif

You, sir, are a friggen saint! Thank you SOO much for answering my petty questions. I only have one last question left:
What about those little square boxes that are in between the capacitor and that silver heatsink to the right? Can I leave them as is?

Yes you can leave them as they are. They are called 'Chockes' or 'Mosfets' if I am not mistaken.

They reach some serious temp. so don't go touching them. This maybe also why people do not stick heatsinks on them, as the glue would need to be somthing special.

After reading my last post I should clarify that the VRM's DO NOT need anything more done to them, as they are already heatsinked.
