I wish I could justify the extra cost of water cooling, but with with the difficulty making mining that much harder, and the crash in value, there's just no way I can spend $80 per block per card, plus pump and rads.

I'm looking for solutions that need no more than duct tape and WD-40...

Are you running the cards in a case? Have you tried adding a side fan if possible?

I have 4x 120mm fans at the front of the case (the old CM Stacker) and the centrifugal fan blowing across the motherboard.

I will try adding an 80mm fan aimed at the top two cards, but I'm guessing the cross wind will just carry that flow straight out the back exhaust.

I use watercooling with my 5870 "sandwich". Core Temp was like yours with standard fan cooling. With watercooling the core temp is between 48 and 52 centigrades from bottom to top of the sandwich.

I have a machine with 4x 6950s and the heat cascades from the bottom card (~75'C) all the way to the top card (~100'C), as each card sucks air off the back of the card below it, which pre-heats the intake air, and makes cooling the core less efficient, so the core is always a higher temp than the card below it.

Are there any tips or tricks to cooling cards that are sandwiched together?

I've already inserted rubber grommets between them for an extra few mm of spacing, and removed the metal face plates off of the input connectors to improve exhaust capacity.

Anything else I can do?
