Better than standard thermal pads?

Alphacool says the material of its Rise Ultra Soft heat thermal pads acts similar to thermal paste. A cooler presses hardest on the highest components, such as voltage converters or VRMs, and in extreme cases this pressure can cause PCBs to bend. According to Alphacool the consistency of the pads prevents those parts from being subjected to increased contact pressure from the cooler. It also states that the pads fill unevenness much better and nestle better against the components, and thus significantly increase the heat transfer between the cooler and the component.

Does not dry out

But that is not the only advantage Alphacool names! The special material also cannot dry out. Usually, the silicone of heat-conducting pads bleeds out over time, which makes them go hard, and the performance of the pads drops rapidly after a certain point. Alphacool says this is not the case with the Rise Ultra Soft Pads: they can be used for a much longer period of time without significantly losing performance.

Cutting to size

Cutting to size? "No problem!", says Alphacool, as long as the foil stays on: it is essential to leave it on the pad when cutting. This makes it easy to cut with scissors, just as easy as cutting paper. The cut edges remain clean (perfectly clean, in Alphacool's words) and do not fray.

What it replaces

Alphacool says the pads offer better performance than standard thermal pads in many respects, and calls them a perfect replacement for old or underperforming pads.
