Beware, some Arctic MX-5 thermal pastes may dry out faster

Less than a year into the MX-5’s existence, the first publicly known flaw is associated with this thermal paste for which it may achieve lower thermal conductivity than expected. This is due to the compound that makes up the paste not holding together properly, and the thermally conductive interface will harden before application, in the tube. Arctic has supposedly already withdrawn these batches from circulation, but one needs to be cautious. Read more “Beware, some Arctic MX-5 thermal pastes may dry out faster” »

Enough TF thermal paste for now, Thermalright introduced the CFX

Until now, Thermalright’s current thermal pastes have been from the TF series. The latest paste (CFX) no longer carries this label. This might be because it no longer fits into the current pyramid due to its properties. The new CFX thermal paste is among the top of the company’s range in terms of parameters, but we believe that you may pay less for it per unit of “ability to dissipate heat” than is usual with Thermalright.

Low price, high thermal conductivity – SPC Pactum PT-4

A new thermal paste has been introduced – Pactum PT-4. Its specifications are admirable, considering the lower price range. The thermal conductivity is more than double that of the previous Pactum PT-2. At least on paper. It could finally be a real competition for the Arctic MX-5. Particularly the application of the PT-4 should be comfortable for its low viscosity. Read more “Low price, high thermal conductivity – SPC Pactum PT-4” »

Arctic kept his word, the MX-5 is on sale. We know the specs

As of March 15, various size tubes of the new MX-5 thermal paste are in stock on Amazon. Arctic thus managed to start the sale on the day they announced in January, when no specifications were yet known. These are already quite detailed and include commonly unspecified specs of electrical insulation. However, something feels fishy here as the basic information about thermal conductivity is missing for some reason. Read more “Arctic kept his word, the MX-5 is on sale. We know the specs” »

After 10 years, a new Arctic paste from the MX series is here – 5

There is no more popular series of thermal pastes than MX from Arctic, which was released in the early phase of the company under the old name Arctic Cooling. Two years ago, Arctic boasted a statistical report on 10,000,000 sold pieces of MX-2 and MX-4 (in total) and now, without prior news, there has been a notice of the upcoming release of MX-5. The exact date is already known and you won’t have to wait long. Read more “After 10 years, a new Arctic paste from the MX series is here – 5” »

Should you remove an SSD sticker before mounting a heatsink?

Here are some questions that everyone who wants to tune their computer to the last detail deals with: Does it make any sense to remove a sticker from a powerful M.2 SSD format? Is it worth the effort and, if something goes wrong, the breach of warranty? How much will the heating be reduced? As a part of detailed tests, we also replaced the original stickers for ones of commonly available materials (paper, plastic foil, aluminum…) just out of curiosity.

Ryzen iGPU and the return of thermal compounds

AMD has released the first Ryzen desktop processors with iGPU this week. APU Ryzen 5 2400G and Ryzen 3 2200G could be attractive for compact computers because it’s easier to cool a single heat source than to cool both CPU and GPU, and the integrated graphics cards of these processors should have performance equal to GeForce GT 1030. However, it also means that the old enemy has returned, thermal compounds. Read more “Ryzen iGPU and the return of thermal compounds” »

Test of “chewing gums”: 3× Arctic and Thermal Grizzly Minus Pads

Thermal conductive pads are useful wherever a thermal paste cannot be reasonably applied. A good example are power supply circuit of graphics cards and processors, so the choice of test subjects was unambiguous. It was less clear, however, what thickness of pads is most effective, if it is better to pay for more expensive ones, and what improvement to expect.

Coollaboratory Liquid Ultra vs. Thermal Grizzly Conductonaut

Coollaboratory is well known among the hardware enthusiasts, mainly thanks to its liquid metals. The model with higher thermal conductivity, Liquid Ultra, is commonly preferred with high power consumption chips since their default compounds are usually of lower quality. To find out whether CLU still pays off, we put it to the ring with an opponent from the Thermal Grizzly workshop, and with Core i5-7600K as the referee.

Test of 27 thermal compounds, part 2

The second round will be especially interesting for people who want to find the best solution for a standard use. The winner is a big surprise. Gelid, Noctua, Phobya, Reeven, SilentiumPC, Thermal Grizzly or Zalman? We can give away that it is not an expected favourite this time. We enjoyed a nice competition in the middle category, where it takes a lot to keep making a difference. We also tested OEM paste from Scythe as a bonus.

Test of 27 thermal compounds, part 1

Thermal pastes can significantly affect the cooling performance, so we have compared several models that represent the current offer. Is the legendary Arctic MX-2 still a good choice? Or is it more reasonable to try newer Cooler Master and Cryorig? There is also a copper Coollaboratory to consider. Well, we have prepared some recommendations, but few warnings too because there are several products that you should rather avoid. Read more “Test of 27 thermal compounds, part 1” »
