Super explosion is also replaced: Intel push new service
This is really great news for crazy overclockers. Intel plans to launch a special fee extension service called "Performance Tuning Protection Plan" (PTPP) in the near future. The specific content of this plan is to charge a certain fee, even if it is really overclocking super "explosion", and burned CPU can also be replaced. The PTPP program was launched as a complement to the normal 3-year warranty service for Intel boxed products. Regrettably, users can only purchase once for each processor. This means that after the second hyperexplosion, there is no way to use the keychain anymore. . At present, PTPP service has been launched on the Intel website and some North American channel retailers: CyberPower, Scan Computers, Canada Computers and Elecrtonics, Altech Computers.
The overclocking processor and specific prices for the Intel PTPP charge extension service are as follows:
- Core i5-2500K: $20 - Core i7-2600K: $25 - Core i7-2700K: $25 - Core i7-3930K: $35 - Core i7-3960X: $35 However, due to processor design in recent years The reason, it is estimated that only players who participate in liquid nitrogen can really use this service...
Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.
Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
