What kind of heat sink should i get

Therefore, it is essential to look beyond the heat sink when designing a thermal solution for a particular application. Some of the important factors that should be considered include heat sink level requirements, component level requirements, system-level requirements, and chassis-level requirements.

A heat sink transfers the thermal energy generated by an electronic assembly or component into a cooling medium. The heat is transferred from a higher temperature region electronic component to a lower temperature region fluid medium by conduction, convection, radiation or by a combination of these heat transfer methods.

The performance of this passive heat exchanger is determined by many factors including the velocity of the coolant fluid, the thermal conductivity of the material, the thermal interface material, and the attachment method. For a specific application, the parameters of a heat sink can be precisely determined through modeling and analysis. To illustrate the key factors affecting the heat sink design performance, we used one of the public projects from the SimScale library— electronics cooling using conjugate heat transfer.

In this project, the heat flow in a heat sink design was simulated. To use it as a template, just create a free Community account here and then copy the project. Thermal resistance refers to the sum of resistances to heat flow between the die and the coolant fluid. These heat flow resistances include the resistance between the die and the component casing, the resistance between the casing and the heat sink thermal interface resistance , and the resistance between the heat sink and the fluid in motion.

Thermal resistance does not factor non-uniform heat distribution and it is unsuitable for modeling systems that are not in thermal equilibrium. Although the thermal resistance value is an approximation, it enables the modeling and analysis of thermal characteristics of semiconductor devices and heat sinks.

Analyses of different heat sink designs are used to determine heat sink geometries and parameters that enable maximum heat dissipation. Complex modeling of thermal characteristics can be achieved by meshing heat sinks using 3D thermal resistances. The image below illustrates the mesh of an electronics enclosure design created in a web browser with the SimScale cloud-based simulation platform.

The hex-dominant parametric only CFD mesh was used to generate the mesh for the 4 volumes 3 solids and 1 fluid. This is used to create refinements and maintain the volumes as different regions to later define interfaces. Heat sinks are designed using materials that have high thermal conductivity such as aluminum alloys and copper. Copper offers excellent thermal conductivity, antimicrobial resistance, biofouling resistance, corrosion resistance, and heat absorption.

When using a liquid compound, apply a paper-thin layer over your CPU using just a dot of the substance on either side of the CPU.

Most manufacturers specify a shelf life of up to three years for packages that are unopened. However, that does not take into consideration the date the tube was produced.

This means that even when enthusiasts buy compounds new, they may have been sitting on some shelf for quite a while which makes it likely that the compound has already degraded. This buying guide is a great resource to use when searching for the best thermal compound to keep any system cool and enhance performance dramatically.

It makes no sense win paired with the rest of the article. Granted that particular pc never did anything other than simple internet browsing mostly email related and word processing.

Just to sum up this buying guide: there is literally no difference in thermal conductivity and price? Allow me to write a competing guide…. Does anyone have any idea what temperature range mosfets screwed to a heatsink likely reach in a e-bike 72 volt dc motor controller? And what type thermal compound paste is BEST for better cooling in this type application? There is an excessive amount of important information available on this topic here but… Is there a website that answers these kind of questions with more definitive answers?

Please e-mail me back at.. What the hell kind of article says the 4 out of 5 linked products are electrically conductive? I mean come on if your going to post a article at the very least you could get the details of the products you link correct..

I see people are generally unfriendly to those of us who are more ignorant when it comes to computers. It's not so much a matter of being unfriendly. I just don't want my answer removed if I recommend a product for you.

I just really believe you need to examine your existing setup first. You may not need to spend any money on a new heatsink. Your issue could simply be that your current heatsink isn't sitting on your processor correctly. First, get the model of your CPU or your motherboard. Canadian Luke Canadian Luke Whether the motherboard needs to be removed mainly depends on the case design. Some cases allow access to the underside of the motherboard for mounting and unmounting the heatsink, but if in doubt, it's perfectly fine to remove the motherboard anyway.
