I’ve collected various pads in the meantime and evaluated lots of feedback. So today I am testing the desired thermal pads in the form of the GP-Extreme from Gelid and in addition the EC360 Silver from Jaden Technologies GmbH in the predefined upper class with 11 W/(m*K) , if one can really trust the manufacturer’s specifications. But can and may one do that? After today’s test I am not only smarter and you in the end of course too, because neither product really belongs there and one even belongs discontinued. But first things first…
Gelid GP-Extreme Thermal Pad with 12 W/(m*K)
With 120 x 120 mm and 1 mm thickness, the pad with 0.28 Euro/ cm² is significantly cheaper than our 11 W/(m*K) reference pad with 0.32 Euro / cm² but also significantly more expensive than the reference pad with 7 W/(m*K), which costs 0.22 Euro / cm². The pad came from a well-stocked retailer, but was hard to come by in this family pack. So the usual 80 x 40 cm packs are not enough for a GeForce RTX 3080, so you need two of them. Then you are at about 18 euros street price. Let’s keep that in mind.
Unfortunately, the pads stick extremely and can also be difficult to separate from the film. Even just pulling off the film can cause it to tear, so you have to be very careful. A very thin spatula or the good old razor blade will help. The rest is not witchcraft and the pads also stick very well to the radiator bottom. The strength is about right, after all.
You should assume that a pad with a suitable thickness will also have enough contact, but consistency and surface texture are also decisive here, because the pad is quite compact and dense. After testing and disassembly, however, you can see only rough imprints, which have almost completely evened out again after 2-3 minutes. The pad was firm to the touch, but it’s just a little too hard to really nestle into all the crevices. This is already a big minus point, because it can be much better.
I have had countless pads in my hands, but this is one that you want to get off your fingers as quickly as possible. The handling is not quite simple, but solvable. It’s just the consistency that really raises questions. We’ll see how that cools in a moment.
EC360 Silver from Jaden Technologies GmbH
The EC360, also bought anonymously, is much smaller and you also need two or an even larger pack. This costs 0,24 Euro/ cm² and is even cheaper than the Gelid pad. Price-wise, you’re slightly above the 7 reference pad. That reads sicherst once interesting, especially since I encountered the pad especially on YouTube constantly and was requested for a test because it was supposedly so good. Here too, of course, I want to know exactly, because one can claim a lot. So did the importer make a stroke of luck here and accidentally or deliberately get the right product from all the offers of the cheaper China suppliers?
Since the dates are on the back, I took a picture of the back as well. The pad with 50 x 50 mm is in principle sufficient for the memory modules and the PWM controller. However, the voltage transformers need significantly more, which is why I wrote about the larger pack. Purely haptically, the pad makes a much better impression than the one from Gelid. It also sticks easily, but is much softer and still more tear resistant. So the consistency comes more along the lines of what has proven to be useful over the years.
You can also see it after use, that a completely different picture emerges. You can even see the RAM labeling and the whole outline of the modules. The pad is slightly thicker than 1 mm and nestles very well even in the cracks and gaps. It also has a slightly lower density according to the data sheet. Still, the pad didn’t tear when I took it off. First of all, a big plus for that.
Before we get to the tests and the results, I would like to introduce you to the reference pads and the test system including the methodology. This is really important in order to be able to correctly classify the results and the assessment later on. We have already made a certain effort, which results in a good compromise between reproducibility and practicality.
