Τhe Gelid HeatPhase Ultra is a new addition to the thermal paste/pads area, with fixed 40x40x0.2mm dimensions and a good retail package of 10 Euro (AMD Edition). The retail package is simple and includes a printed installation guide that should be read before installing the product. The installation process was OK, in the sense that you need to be careful to follow the steps that the printed manual suggests to get the best possible result. The pad dimensions are more than OK, and in our AMD 7950X superpass the CPU dimension, which is a good thing, other AMD processors will be covered as well.
Let's now pass to the most important aspect of this product, how does it perform? We tested four different TDPs with the AMD 7950X and in most of them the Gelid HeatPhase Ultra manages to come very close to the Noctua NH-H1 thermal paste, which is a good thing and in most cases, we can say are "equal". Things do get further improved as time passes, since the Gelid HeatPhase pad, does need a "break-in" period to perform best. For that purpose, we performed all tests another day and we got slightly better results.
Removing the CPU cooler from the CPU isn't very hard after tests are finished and as time passes the pad will become somewhat solid again so you won't have any difficulty cleaning it up. Overall we do find the Gelid Heatphase Ultra a good product, much better than the previous Gelid thermal paste we had in our labs and compared with other thermal pads we had also better. If you are in the market for a product that will last for a very long time and won't degrade its performance as time passes, then you should get one and relax. Don't be surprised to see CPU temperatures improving day-by-day as you stress this product. Good work from Gelid, and it earns our Best Buy Award.
