My graphics cards get hot if I enable K-Boost in the PrecisionX software. Without K-boost and mild overclock GPU temp stays in the mid 30's, with K-boost temp rises to 80's. I would like the system to run full steam (though I am currently playing Arma 3 mods, so FPS is still not ideal regardless of specs).


Someone experienced, please advise:

- Is my set up not enough to run 3 cards full speed?
- I don't remember having this issue with push/pull fans on the rads, maybe it makes that much of a difference? (Or perhaps I never enabled K-Boost, can't remember)
- One of the cards coil whines I believe. I hear a noise when I open certain games. Reading says that it is not uncommon, but just mentioning.
- To the touch, it's the top cards that's hot, the bottom two are reasonable. Could it be the type of bridge I'm using? Or is it just bc top card is primary?
