Cooling

HIS IceQ Radeon HD 5750 1024MB

A traditional IceQ cooler with a turbine on one end that drives air through the heatsink and out of enclosure. Such coolers are usually very quiet and effective. Let me say that this graphics card worked fine at the 5770 clock rates. Overclocking it from 700 to 850 MHz resulted in no issues, and the cooler performed just fine.

AFOX Radeon HD 5770 1024MB

A finned oval heatsink with a large and slow fan in the middle. This cooler is almost noiseless.

PowerColor Radeon HD 5770 PCS+ 1024MB

A similar cooler, only the heatsink is rectangular. Reinforced with a copper plate. Nearly noiseless as well.

XFX Radeon HD 5750 512MB

Yet another similar cooler. Nearly noiseless.

Sapphire Radeon HD 5770 Vapor-X OverClock Edition 1024MB

Vaporizing chamber is the key feature of Vapor-X coolers. Liquid coolant vaporizes on the hot surface, the resulting vapor condenses on the cold surface, and is taken to the hot surface again. This recirculation goes on inside a degasified chamber, controlled by a complex capillary system. Vapor-X chambers are very thin, mounted directly on GPU crystals.

This solution only cools the core, so a large heatsink with a slow fan in the center is added to help cool the rest. This solution is noiseless.


Traditionally, we monitored temperatures using RivaTuner.

Sapphire Radeon HD 5770 Vapor-X OverClock Edition 1024MB



XFX Radeon HD 5750 512MB



As we can see, all cards are cool enough. But let me stress the efficiency of the HIS cooler one more time. Obviously, it can easily manage a Radeon 5770 card.
