None of the cards tested poses any particular problem in terms of the temperatures inside the casing. Nevertheless those Radeon HD 7970s that don't expel hot air from the casing do cause internal heat levels to rise and the HIS, MSI Twin Frozr III and Sapphire SuperClock Radeon HD 7950s and the Radeon 7970 Lightning tend to expel more hot air towards the hard drives than the other cards.
