thermal compound application

Even though every microprocessor has its own internal design, all microprocessors share a same basic concept – which we will explain in this tutorial. The computer you are using to read this page uses a microprocessor to do its work. Using a thermal paste for cooling down the increased temperature of the CPU is a must for enthusiasts who seek peak performance from their systems. The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output.

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The CPU is centrally located on the motherboard.

Thermal paste performance in CPU environment

All computers, large and small, must have a central processing unit. Traditionally, the term “CPU” refers to a processor, more specifically to its processing unit and control unit (CU), and with a thermal paste that is used for dissipating CPU temperature, distinguishing these core elements of a computer from external components such as main memory and I/O circuitry. The data come from the RAM and the units (keyboard, drives etc.). After processing, the data is send back to RAM and the units.

How it will process data will depend on the program. A microprocessor — also known as a CPU or central processing unit — is a complete computation engine that is fabricated on a single chip. As Figure 1 shows, the central processing unit consists of two parts: The control unit and the arithmetic/logic unit. The form, design and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged.

The CPU continually receives instructions to be executed. The program can be a spreadsheet, a word processor or a game: for the CPU it makes no difference, since it doesn’t understand what the program is actually doing. The first microprocessor was the Intel 4004, introduced in 1971. Now using a thermal compound to disperse this increased temperature is the only solution we can think of so far.

  1. We will take a look inside a generic CPU architecture, so you will be able to understand more about Intel and AMD products and the differences between them.
  2. The microprocessor is the heart of any normal computer, whether it is a desktop machine, a server or a laptop.
  3. This control center, called the central processing unit (CPU), with a special thermal paste , is a highly complex, extensive set of electronic circuitry that executes stored program instructions.
  4. The term has been used in the computer industry at least since the early 1960s.
  5. Since the CPU carries out a large share of the work in the computer, thermal compound can stop it, data pass continually through it.
  6. The CPU (Central Processing Unit) – which is also called microprocessor or processor – is in charge of processing data.
  7. The microprocessor you are using might be a Pentium, a K6, the thermal grease is used between the heatsink and CPU surface, a PowerPC, a Sparc or any of the many other brands and types of microprocessors, but they all do approximately the same thing in approximately the same way.

Each part has a specific function. Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and “executes” them by directing the coordinated operations of the ALU, registers and other components. The thermal paste on heatsink surface will do the work perfectly if it’s applied correctly on both surfaces. This is the basic principle of what takes place within most data processing units, even if the outcome is very different.

It just follows the orders (called commands or instructions) contained inside the program. The 4004 was not very powerful — all it could do was add and subtract, and it could only do that 4 bits at a time. Before we discuss the control unit and the arithmetic/logic unit in detail, we need to consider data storage and its relationship to the central processing unit. Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip. In a mobile phone, for example, data from the SIM card will be submitted via the CPU, whereas on a games console, it will be actions send via the controller.

Heatsink Usage on CPU surface

These orders could be to add two numbers or to send a piece of data to the video card, for example. But it was amazing that everything was on one chip. Computers use two types of storage: Primary storage and secondary storage. A CPU thermal paste can go far away with helping dispersing the generated temperature of CPU caused by heavy workloads. An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously called microcontrollers or systems on a chip (SoC). Some computers employ a multi-core processor, which is a single chip containing two or more CPUs called “cores”; in that context, single chips are sometimes referred to as “sockets”. Each instruction is a data processing order.

The program, which is stored inside the hard disk drive, is transferred to the RAM memory. Prior to the 4004, engineers built computers either from collections of chips or from discrete components (transistors wired one at a time). A heat sink cannot be used without a thermal paste to connect it with the CPU. The 4004 powered one of the first portable electronic calculators. The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data. Array processors or vector processors have multiple processors that operate in parallel, with no unit considered central. This information instructs the CPU on how this data should be processed, as well as the value of the data itself.

Types of heat sinks for CPU colling purposes

A program is a series of instructions to the CPU. If you have ever wondered what the microprocessor in your computer is doing, or if you have ever wondered about the differences between types of microprocessors, then read on. Now what kind of heat sink to use for your CPU? Is any heat sink will just do the job as it is? For this reason this part of the reading will discuss memory in the context of the central processing unit. Computers such as the ENIAC had to be physically rewired to perform different tasks, which caused these machines to be called “fixed-program computers”. What we call instructions is program code.

applying thermal paste on CPU surface the right way

The salad bowl is like a temporary register, it is for storing the salad waiting to take back to the fridge (putting data back on a disk) or for taking to the dinner table (outputting the data to an output device). For example, a 386 needed 6 clock ticks to add a number to a sub total. A job which the 486 manages in only two clock ticks, because of more effective instruction decoding.5th and 6th generation CPUs can execute more than one of those operations in one clock tick, since they contain more processing lines (pipelines), which work parallel. The first CPUs could only work with whole numbers. Therefore, it was necessary to add a mathematical co-processor (FPU), when better math power was needed.

Using a thermal paste between CPU and heat sink surface

Later, this FPU was built into the CPU. It is said that Intel’s CPUs have by far the best FPU units. Processors from AMD and Cyrix definitely have a reputation for providing sub standard performance in this area. But, you may not utilize the FPU. Going for a heat sink thermal paste is what we kept recommended for a good CPU cooling structure. That depends on the applications (user programs) you are using.

Common office programs do not use the floating point operations, which the FPU can handle. However, 3D graphics programs like AutoCad do. And all 3D-games like Quake rely heavily on FPU performance! Thermal paste components are not easy to recognize though in this matter. Therefore, if you use your PC in advanced design applications, the FPU performance becomes significant. For some users, it is only of limited importance.

Another company to use VLIW is TransMeta with their portable Crusoe processor. If you look at a motherboard, you will see several tracks or paths. Note that the counter top (RAM) is faster to access than the fridge (disk), but can not hold as much, and can not hold it for long periods of time. One is that the clock frequency increases, as we will see later – the faster, the better. These tracks are wires that connect the several circuits of the computer.

The composition of CPU thermal paste

The corners of the cutting board where we temporarily store partially chopped veggies are equivalent to the registers. But what can the CPU do in one clock tick. The problem is that with higher clock rates, these wires started to work as antennas, so the signal, instead of arriving at the other end of the wire, would simply vanish, being transmitted as radio waves. The corners of the cutting board are very fast to access for chopping, but can not hold much. As far as thermal paste is concerned, you don’t need to think more about cooling down your CPU increased temperature in high-end gaming systems. That is critical to its performance.

As the processor clock signal became very high, one problem showed up. The counter top is the equivalent of the computer’s motherboard – everything is done on the counter (inside the computer). The cutting board is the ALU – the work gets done there. Now a thermal compound is something that every computer user must use for a solid system performance. Hence, Intel has had many problems with their 64 bit Itanium processor, which comes in VLIW design. The motherboard where the processor is installed could not work using the same clock signal. The recipe is the control unit – it tells you what to do on the cutting board (ALU). Space on the counter top is the equivalent of RAM memory – all veggies must be brought from the fridge and placed on the counter top for fast access.
