Good luck! If the V540 works and is a 2x8GB 2xNaviGL card, I might have to pick one up in June. (I just tried to Best Offer that seller on
another MI25 for crossfire WX9100s; I'm thankful he declined my lowball. I want that dual Navi, if it'll work in Windows or Linux, lol)
Here's my card, if you want
inspiration on cooling.
I removed the factory MI25 shroud, and made my own. The Aluminum tape 'shroud' was chosen for a couple silly reasons and 1 good reason.
Good:
-It's impermeable and 'forms' where set. Meaning (unlike 'duct/duck' tape), it doesn't 'inflate' when pressurized, and it'll be less likely to de-adhere and decompose w/ heating-cooling cycles (and dust accumulation).
Silly:
-The aluminum is a good IR
reflector, and (at least in my mind) helps concentrate the radiant heat into the exhausted airstream.
-I assume the aluminum tape has some kind of effect on EMI/RFI. (For all I know in actuality, I just made a very messy
antenna; doing the opposite of 'helping EMI'. Basically, I gave my 16GB Vega a literal (figurative) "Tinfoil Hat".)
