It's hot ! Cool your PC properly ! (part.3)

avatar

With the last two articles, we learned a little more about how heat dissipation works in our PCs and the reflexes to adopt when maintaining our equipment at the right temperature. Now it is time to make good resolutions and pay some attention to our installation. We will also see these actions not to be repeated and what to do in case of difficulty related to the cooling of the whole. Do you have something to refresh yourself with and ready to know more? If so, all you have to do is follow the guide !

Test and keep an eye on your equipment

It is one thing to mount your PC properly and give it a consistent air flow. Nevertheless, it should not be overlooked that your computer companion will be more or less solicited, depending on its intensive use or not, from the ambient temperature or even from a design defect on a very particular part. All this will inevitably cause the internal temperature of your enclosure to change. There are many other parameters to take into account that could lead to a degree deviation that could then appear : the application of the thermal paste, the assembly carried out, the location of your box, overclocking, an approximate bios adjustment, etc.... In order to check the temperatures of your components, it is necessary to monitor the internal temperature of each of them. Fortunately, our chipsets include probes that can give you essential information on this subject.

First, it is strongly recommended to practice what is called a "stress test" when you first start up your device. This type of software will increase the workload of your CPU/GPU, until it monopolizes its attention. Practical to check the stability of your assembly, this type of application will also give you an idea of the maximum temperature reached, when your equipment is fully charged. Many software programs are available to perform this task. However, I can recommend enough OCCT for your processor and Uningine benchmark for your graphics card. Both solutions are completely free of charge and give an overview of the performance of your components.

Once installed, you're off for hours of serial testing ! Allow 6 hours of OCCT to validate the stability as well as a precise idea of resting and charging temperatures. As for Uningine, allow a good hour of use. If you do not encounter any artifacts, image jumps or BSOD (Blue Screen Of Death), with temperatures not exceeding the maximum heading of your elements, you are guaranteed to have sufficient cooling for your configuration. To know them, refer to the official website of the manufacturer.

In general, it is considered that the maximum temperature of a core should not exceed 90°c and the total 70°c for the CPU. Graphics cards can also be mounted up to 90°c. However, keep in mind to keep a sufficient margin in case of high heat (as is currently the case) and try by all possible means to limit the release of heat. Who can do the most, can do the least too.

Are you comforted ? From now on, it is up to you to regularly monitor the condition of your elements. To do this, use and abuse monitoring software. This is clearly not what is missing under Windows : HWMonitor, Intel XTU, AMD Ryzen Master, GPU-Z... The choice is important to you in order to do the best you can ! Do not hesitate to change the speed of your fans, if you are equipped with them. A good part of this software allows it and can certainly save your life, in case of a hard blow ! In addition, you will be able to scale the rotation intensity by degree steps. Particularly useful, in order to automate this process.

It's too hot, I'm going to use my home fan to cool my computer !

What are you doing ?! Although the idea is attractive at first glance, it completely invalidates the very principle of air diffusion, which is designed for this purpose in the case. If you hope to gain a few degrees with this method, you simply risk producing the opposite effect, all with a profusion of dust diffused on a large scale over your entire configuration. In this case, it is better to add a few case fans if you have space available.

Adding thermal paste will not increase the dissipation effect. On the contrary, contact and pressure may well make the phenomenon less effective than before. Only one solution: remove the existing paste and put back a layer, having first cleaned everything thoroughly.

In the next episode, which will certainly be the last, we will see together the practical case of monitoring under Linux and the effective method of "underclocking" ! Until then, get in the cool and take care of your PCs !
