Hong Kong-based PC circumstances and cooling specialist Gelid has launched a brand new thermal pad product dubbed HeatPhase Extremely. As hinted at by the title, the corporate claims this thermal pad makes use of a phase-change materials and provides the last word in thermal switch effectivity between a processor and cooling block. Gelid has plenty of massive claims for its HeatPhase Extremely, which it says is simpler to use, provides improved sturdiness, and delivers higher efficiency than conventional thermal pastes.
It is obscure how the HeatPhase Extremely thermal pad we see within the product photos is a part change materials (PCM). In response to our regular understanding of a PCM, it enjoys a really excessive latent warmth capability, which is absorbed or launched when the fabric’s part adjustments. A part change may be from gasoline to liquid, from liquid to strong, or vice versa. How that works with this fairly normal-looking pad, which claims to be “ultra-durable and non-curing… [and] no-bleeding,” is troublesome to fathom from the product pages alone.
Shifting alongside to different claims by Gelid, there’s the HeatPhase Extremely’s efficiency. Gelid has offered a efficiency chart, embedded under, which it says exhibits how nicely the HeatPhase Extremely thermal pad performs in direct comparability to a conventional thermal pad, and Gelid’s personal GC Excessive thermal paste.
We now have some expertise with GC Excessive and it was the runner-up within the hotly contested finest price range thermal paste class in our Finest Thermal Paste for CPUs 2023 function, which assessed 90 pastes.
In Gelid’s testing with an AMD 7950X, the HeatPhase Extremely pad saved the CPU about 2 levels Celsius cooler below load in comparison with GC Excessive paste (79 levels Celsius). We expect these outcomes are literally very shut and possibly inside the margin of error, but when HeatPhase Extremely is as an alternative simply an equal performer to GC Excessive, it’s nonetheless a really legitimate various for the explanations outlined under.
Thermal pads can have inherent properties which can be preferable to pastes. Gelid says the HeatPhase Extremely is easy to use or take away. Some photos present a protecting movie being eliminated as soon as the pad is in place on the cooler heatsink. Different thermal pad niceties corresponding to a assured evenness of software stay true right here. Gelid additionally claims its new product is ultra-durable, with an extended life throughout which it gained’t treatment, harden, or in any other case degrade. Furthermore, the non-electrical conductive materials is claimed to remain in place with out spreading below stress.

Gelid is now promoting HeatPhase Extremely thermal pads pre-cut for contemporary Intel or AMD processors. Within the desk above you may see the pad dimensions for both CPU model. The AMD pad prices $10, and the marginally smaller Intel pad is $9.50. It looks as if you solely get one pad for the value, however we’d nonetheless like to offer this a check within the labs and see the way it stacks up.
