Which MOSFET / RAM sinks do you use?

I have a third 7970 I want to disasemble to mount an Antec h2o 920 on and am looking at MOSFET/Ram sinks but can't find anything specific though I would imagine they are all universal.

Just pick up a bracket, and use a fan over the bare mosfets. Actually is just fine instead of applying thermal tape and heatsinks to them. http://triptcc.com/shop/

Well if the mod was successful I would want to Crossfire them. I am looking to either sell two of them or (depending on how the mod goes) use another one in my main PC after using two 920's.

It is a test the waters type deal atm.

The bracket is only $10 and its cheaper than any other solution besides zip ties...

wouldnt it interfere with a crossfire setup?

Not generally. I have seen people with 2x all in one cooler kits installed, one on each card.

It all depends on the board, and which GPU you are going to mount the water cooler to.

I would still sink the mosfets. That sounds like bad advice to me. Do you have any temp readings to show how the bare mosfers perform?

With a fan, yes.

I would use some enzotech sinks and a side fan to make sure that they get a little airflow.

Many HD79XX cards have a ram/VRM heat plat build on to it to support cooling and to add stability to the PCB. If your card has one I would upgrade thermal tap to Fujipoly and then stick some stick on aluminum heat sinks on the stock heat plate where possible. Some of the better cards have heat sink plate with fins buy some don't.


fujipoly is much better at soaking up heat than the sticky thermal pad that is found on stick on heat sinks.

A heat sink/block will only work as well as the TIM/Thermal Pad will allot it to work to a certain degree. TIM/THermal pad is very important.
