![]() ![]() One important one being electrical conductivity.Īs the name suggests, a Thermal Pad is a soft pad that acts as a Thermal Interface Material. There are some less expensive thermal pastes or compounds that do not fulfil all the qualities of a decent thermal paste.You have to apply the Thermal Paste very carefully and make sure that you leave no air gap.Can get messy, especially if you are applying for the first time.You can get very good quality thermal compound from reputable manufacturer for very little price. Just apply it on the surface of the IC (in the form of a dot or x-shape). Usually, thermal paste or compound come in a syringe (or similar dispenser). As it is essentially a liquid, you can use it on all types of surfaces and the surface doesn’t have to be flat.Thermal Paste is very efficient at transferring the heat away from the surface of an IC even with minimum quantity.Additionally, you can use a cooling fan to further dissipate the heat from the heat sink. Most CPU and GPU manufacturers recommend thermal pastes as the main thermal interface material between the surface of the chip and the surface of the heat sink. But the important thing is the Thermal Paste acts as an excellent filler of the gap between the chip and the heat sink. There are several discussions on the amount of thermal paste you need to apply and also the different procedures on how to apply. You have to apply this thermal paste between the IC (CPU, GPU, etc.) and the heat sink. Some other names for Thermal Paste are Thermal Grease, Thermal Compound.Īs the name suggests, thermal paste or compound is in the form of, well, a paste (a semi-solid liquid). Thermal Paste is one of the most popular and widely used Thermal Interface Materials. Here are some of the common Thermal Interface Materials: This will not only eliminate the air gap but also acts as a thermal bridge between the surface of the component and the heat sink. What they do is fill the air gap with a thermally conductive material. This is where different Thermal Interface Materials come into picture. So, the air gap between the surface of the component and the heat sink will act as an insulator and restricts the transfer of heat. We know that air is a very bad conductor of heat. If we take a heat sink and place it on top of a power device (MOSFET), and IC, or any “hot” electronic component, there will be tiny air gap between these two surfaces.Įven though they appear to be in contact, there is still some game will air filled in that gap. But Thermal Interface Materials play an important part in the heat transfer process. We use heat sinks and cooling fans to keep the electronic devices cool. Thermal Paste vs Thermal Pad: Which Provides Better Heat Transfer?Ī Brief Note on Thermal Interface Materials (TIM).A Brief Note on Thermal Interface Materials (TIM).Question Make sure you do a hard CMOS reset when putting in a raptor lake in a motherboard that previously had Alder. Put back old cpu to update motherboard, black screen, help! Question Upgraded CPU without updating motherboard, black screen. Question my pc keep restarting when i try to put passwards after change the cpu Thermal paste has glued the cpu to the cooling plate. Question connected AIO cooler to cpu with the plastic still on.

Question HW Info detecting thermal throttling on i9 13900k at 90 degrees with mce off Question why does the intel 12700h have lower temperature than 6800h Question CPU Performance Being Limited Although Temperatures Are OK ![]() Question New Build 13700KF with NH-D15S Thermal Throttling 100☌ Then the chances of getting paste in the socket skyrocket, and that can be an issue. If using an electrically conductive paste or if you decide to try and pull the cpu out of the socket before cleaning up the mess. Too much paste doesn't hurt anything except in 2 occasions. Of course if you do do a pea-blob method and use a kidney-bean sized blob, you'll get the same coverage as spatula, but you'll also get plenty of seepage where the paste is squeezed out the sides like too much jam in a pb&j sandwich. An X pattern or better yet, a credit card/spatula spread to cover the entire IHS is preferable to pea-blob methods, this ensures all the edges/corners are covered. This puts the chips very close to edges/corners. That doesn't work for later Ryzen or GPU as Ryzens use 3-6 dies under the IHS, spread out to better spread heat and prevent buildup and transfer to the neighboring chips. So a decent sized blob in the middle, with firm but even pressure applied by the heatsink install was perfect, covered everything, even if it just left a circle and didn't quite reach the edges/corners. ![]() With Intels and older Ryzen and FX etc, the actual die is a small single chunk of silicon directly in the center of the IHS cover.
